    Introduction

     Testicular cancer is one of the most common type of cancers to affect men. Medical herbs are increasingly considered useful complementary treatments for cancer. The aim of this study was to evaluate the cytotoxic, antioxidant, and anticancer capacity of Melia azedarach L. extract on testicular cancer TM4 cells.

    Materials & Methods

    The TM4 cells were treated with various concentrations of leaf Melia azedarach L. extracts (10, 25, 50, 75, 100, 150, 250, 750, and 1000 µg ml⁻¹) for 24, 48, and 72 hours. MTT assay and real-time PCR were used for the evaluation of plant extract cytotoxicity and gene expression (CAS8, CAS9) analysis, respectively. Anthocyanin content and DPPH radical scavenging activity were evaluated for the antioxidant potential of plant extract. Statistical tests included one-way ANOVA, which was imported to SPSS V.18, and the significance level was considered less than 0.01.

    Results

    MTT assay results revealed a decline in live cells with increasing concentration of plant extract in a dose- and time-dependent manner. Cell viability was significantly (P < 0.01) reduced, especially at a concentration of 1000 µg ml⁻¹. Also, the CAS8 gene expression was increased in TM4 cells treated with bitter olive extract at 174.2 µg ml⁻¹ concentration (IC50), whereas the CAS9 gene expression was decreased. Moreover, a higher DPPH activity and anthocyanin content were found with increasing plant extract concentration.

    Conclusion

    Ethanolic extracts of Melia azedarach L. have antioxidant activity, which could significantly inhibit the proliferation of testicular cancer TM4 cells (A549) by inducing apoptosis and CAS8 gene expression. Therefore, it could be regarded as an additional treatment for testicular cancer.

    Background

    Colorectal cancer (CRC) is one of the most common malignant tumors in humans. The influence of natural plant compounds is widely acknowledged today. Artemisia sieberi has anti-bacterial, anti-fungal, and anti-inflammatory properties.

    Objectives

    The aim of the forthcoming study is to investigate the impact of Artemisia sieberi plant extract on the expression of key genes within the apoptosis signaling pathway of the HT-29 cell line.

    Methods

    In this study, RNA extraction and cDNA synthesis were conducted subsequent to the culturing and treatment of HT-29 cancer cells with plains herb extract. A real-time PCR test utilizing specific primers for Bax and Bcl-2 was then performed using the Rotor-Gene Q machine. Additionally, an MTT assay was conducted to assess the toxicity of the Artemisia sieberi extract.

    Results

    The test revealed that as the concentration of the studied extract increased, cell viability decreased in a dose-dependent manner. The calculated IC50 value for the plains herb extract was found to be 0.44 µg/mL. Furthermore, the levels of Bax and Bcl-2 genes in cells treated with the plains herb extract were determined to be 1.48 and 0.45, respectively, indicating an increase in the expression of these two genes.

    Conclusions

    Given the low toxicity of the Artemisia sieberi extract observed in the MTT test and its potential to increase the expression of apoptosis-inducing genes in intestinal cells, it appears that Artemisia sieberi extract could be employed as a therapeutic supplement for the prevention and treatment of gastrointestinal cancers.

    Introduction

    Glioblastoma (GBM), which is a heterogeneous and aggressive type of brain tumor, is known for its poor survival outcomes. The treatment of GBM remains challenging primarily due to the drug resistance to the current standard therapeutic option, temozolomide (TMZ). Researchers are currently focusing on developing an appropriate alternative combinatorial therapeutic to enhance treatment outcomes. D-limonene (DL) is a monoterpene derived from citrus fruit. This study aims to assess the impact of combining DL with TMZ and explore its potential mechanism of action in U87MG and LN229 GBM cells.

    Methods

    The effects of the combined treatment of DL and TMZ were assessed on various cellular aspects, including cell viability, anchorage-independent cell growth, and DNA damage. Furthermore, the influence of this combination on cell cycle progression, cell migration, and cell death was also investigated.

    Results

    The combination of DL+TMZ demonstrated a synergistic effect, resulting in reduced cell proliferation and suppressing the colony formation ability of a single cell. Treatment with DL and TMZ arrested the cells in G0/G1 phase. Furthermore, the DL+TMZ combination induced apoptosis by upregulating the expression of Bax, and Caspase (CASP)-3, while reducing the expression of the Bcl-2 gene in GBM cells. In addition, the combined treatment of DL+TMZ significantly decreased the expression of matrix metalloproteinase (MMP)-2 and MMP-9, expression, indicating inhibition of cell migration in GBM cells.

    Conclusion

    In conclusion, the combination of DL and TMZ demonstrated a synergistic effect in reducing cell proliferation, suppressing colony formation, inducing apoptosis, and inhibiting cell migration in GBM cells. These findings suggest the potential of DL+TMZ combination therapy as an effective treatment for GBM.

    The Hantzsch reaction created a new series comprising 1,4-dihydropyridine pyrazoles and oxa diazoles (DHP) by initially synthesizing DHP esters, then its carbohydrates, and subsequent treatment with hydrazine. Pyrazole derivatives (Am1 and Am2) were obtained via the reaction of hydrazines with acetylacetone or ethyl acetoacetate, whereas the oxadiazole derivative (Am3) was prepared via reaction with carbon disulfide in an alkaline medium. The prepared compounds were identified using spectroscopic techniques (FTIR, 1H and 13C NMR, and mass spectrometry). The anti-breast cancer activity of new compounds was evaluated. This cytotoxicity activity afforded that compound (AS) was the strongest in this group together with an IC50 = 100.24µg mL-1, whereas compound (AT) demonstrated the lowest potency, with an IC50 value of 300 µg mL-1. The Hantzsch reaction was used in the synthesis of a new 1,4-dihydropyridine that has pyrazole and oxadiazole moieties. The activity of in vitro cytotoxicity (MTT cell viability assay) was determined. In vitro MCF7 cells were used in the evaluation of the cytotoxicity activity (MTT cell viability assay) of new compounds. This cytotoxicity activity meant that compound (AS) was the strongest in this group, with an IC50 of 100.24 µg mL-1, while compound (AT) had the least potency, with an IC50 value of 300 µg mL-1. Based on our findings, we can infer that 1,4-dihydropyridine derivatives (DHPs) are noteworthy heterocyclic compounds with pharmacological potential.  This cytotoxicity activity meant that compound (AS) was the strongest in this group, with an IC50 of 100.24 µg mL-1, while compound (AT) had the least potency, with an IC50 value of 300 µg mL-1.

    Background

     Due to the fact that colon inflammation is one of the most common diseases in the country, the interest in using herbal medicines to cure intestinal inflammation is increasing day by day.

    Objectives

     In the present research, we aimed to identify the target molecules in the immune system by analyzing the transcriptome of these diseases and using the virtual screening technique to search for plant compounds that have antagonistic capabilities for these receptors. Also, by using this in vitro culture, check and confirm the anti-inflammatory properties of these compounds.

    Methods

     The population study includes 200 human transcriptome runs, about 60 thousand compounds related to medicinal plants, and in vitro experiments with at least three experimental replicates and three technical replicates. In this study, the anticancer and immunomodulatory effects of aqueous extracts of rosemary and nettle medicinal plants were investigated as a promising source of cancer treatment against the AGS cell line derived from gastric cancer (AGS-Cell-DGC). IC50 of the extracts was determined by MTT assay. Flow cytometry and real-time PCR (RT-PCR) were measured.

    Results

     The MTT test on the survival percentage of AGS cell line (90%) derived from gastric cancer showed that the highest amount of live cells was observed in control, and the lowest amount was observed in the simultaneous combination of rosemary and nettle extract and then nettle (100%). The highest expression of interleukin 1-beta (IL-1β) gene occurred in the control, and the lowest expression occurred in the simultaneous combination of nettle and rosemary extracts. The highest expression of tumor necrosis factor-alpha (TNF-α) gene occurred in the control, and the lowest expression occurred in the simultaneous combination of nettle and rosemary extracts.

    Conclusions

     The results showed that the highest amount of live cells was observed in the control, and the lowest amount was observed in the simultaneous combination of rosemary and nettle extract and then nettle (100%) alone. However, further clinical trials are needed to confirm the results of this research.

    The focus of many investments was pulled towards magnetic nanoparticles and their extending range of implementations in medicine and biology that particularly include drug delivery, magnetic resonance imaging, and cancer treatment through hyperthermia, as well as other objectives such as pollutants degradation and compounds separation. This work attempted to arrange cobalt ferrite nanoparticles (CoFe2O4 NPs) by taking advantage of starch aqueous solution combined with a calcination process at 500, 600, and 700 °C. The acquired prepared NPs, which were muti-dimensional shape, were configured by the employment of X-rày Diffraction (XRD), Vibràting Sample Màgnetometer (VSM) and Energy Dispersive X-rày (EDX), Field-emission Scànning Electron Microscope (FESEM), and Ràman spectroscopy. The outcomes of VSM analysis were indicative of a ferrimagnetic attitude, while the performance of MTT assay helped in assessing the cytotoxicity of CoFe2O4 NPs on colon càncer cell (CaCo2), oral squamous cell carcinoma (OSCC) CAL27 and mouse embryò fibròblast cell (NIH-3T3) lines, which resulted to be non-toxic towards cancer and normal cell lines. Considering these observations, we can approve the ideal applicability of our synthesized CoFe2O4 NPs in medical implementations similar to drug delivery and non-medical utilizations.

    Background

    Considering the global prevalence of cancers and the complications of common cancer treatments, there is growing interest in using medicinal herbs to complement cancer treatments and reduce treatment’s side effects. Therefore, we investigate the effect of the extract of Nasturtium on the viability of oral cancer cells.

    Materials and Methods

    In this experimental study, we prepared aqueous extract from Nasturtium leaves and human oral cancer cells(OCC‑24) and normal fibroblast cells (HF2FF cell line) from a cell bank. Then the toxic effect of different concentrations of the extract on cell viability after 24–48 hours of exposure was investigated with the methylthiazol tetrazolium assay. Ultimately, the optical density was measured at 570 nm by an Elisa Reader. Analysis of inhibitory concentration 50 (IC50) was also performed. The data were analyzed by paired Student’s t‑test and one‑way analysis of variance.

    Results

    Data showed that the extract had statistically significant anticancer effects in concentrations above 0.125 mg/ml for 24‑hour exposure and in concentrations above 0.5 mg/ml for 48‑hour exposure (p‑value <0.05). Also, this extract had an adverse effect on the viability of normal cells; however, this effect occurred in high doses of the extract (p‑value <0.05). Analysis of IC50 criteria indicates that with increasing time, a higher concentration of the extract is required to inhibit the viability of cancer cells.

    Conclusion

    Because of the results, this aqueous extract can be suggested as a potential therapeutic agent in oral cancer. The best concentration of the extract was found to be 1 mg/ml.

    Background

    Clays and clay minerals have great potential for exerting positive impacts on human health and implementation in medical applications. They are industrial minerals used in various medical applications, like drug delivery. Considering the abundance of clay resources in Iran, we decided to investigate the role of natural clays in peripheral blood mononuclear cells (PBMCs), as effective immune system cells that provide the health of the body in disease and standard times. Investigating the cytotoxicity of these minerals on PBMCs helps to understand their performance in medicine and the treatment of patients.

    Materials and Methods

    The studied clays, including bentonite, zeolite, and sepiolite, were prepared from Iran mines, and their characterizations were scanned by x-ray fluorescence (XRF), x-ray diffraction, and cation-exchange capacity (CEC) determination. PBMCs were isolated by Ficoll-Hypaque density gradient centrifugation, and 200000 PBMC cells were exposed to different concentrations of clays (1-1000 µg/mL) for 48 h in 96-well cell culture plates. Cell cytotoxicity response was determined using 3-[4, 5-dimethylthiazole-2-yl]-2, 5-diphenyltetrazolium bromide (MTT) assay.

    Results

    Bentonite inhibited cell proliferation after 48 h of incubation at a concentration above 0.05 mg/mL, whereas zeolite inhibited cell proliferation at 10 and 5 mg/mL. Sepiolite does not have any cytotoxic effect at all of the concentrations. CEC for bentonite, zeolite, and sepiolite were 86 cmol(+)/kg, 15.5 cmol(+)/kg, and 3.54 cmol(+)/kg, respectively, and showed a direct relationship with cell growth. 

    Conclusion

    The cytotoxicity of the investigated clays is less than those reported in the literature review. This suggests that the studied clays with beneficial properties have great potential to be used in medicine, taking into account the size, type, and concentration of clays. In vivo and long-term studies on bio-culture and biodistribution are essential to understand better the role of the studied clays. Furthermore, our results could provide a new perspective on the safety of using cheap and naturally available clays in medical and industrial applications.

    Backgrounds

    The fungal pathogen Candida albicans is a cause of biofilm formation in patients with oropharyngeal candidiasis. Saccharomyces boulardii is a nonpathogenic fungal probiotic that plays an important role in preventing or treating intestinal diseases. This research aimed to determine the inhibitory effect of S. boulardii probiotic yeast on biofilm formation capacity of C. albicans, which is one of the main virulence factors.

    Materials & Methods

    In this study, 33 oropharyngeal samples were collected from patients with suspected oropharyngeal candidiasis (OPC). The inhibitory activity of S. boulardii against biofilm formation capacity of C. albicans was investigated by crystal violet-based staining (CVS) and MTT reduction reaction. The collected data were analyzed using student's t-test in SPSS statistical software.

    Findings

    In this study, the probiotic yeast S. boulardii reduced the pathogenicity and virulence of C. albicans in vitro. According to the results of CVS and MTT assays, a considerable reduction (p< .001) in the biomass and viability of C. albicans biofilms was observed after 48 hours of incubation in the presence of S. boulardii extract.

    Conclusion

    There was a significant association between S. boulardii extract concentration and biofilm formation in both CVS and MTT assays. Biofilm formation decreased with increasing S. boulardii extract concentration and incubation time in both methods compared to the control group.

    Introduction

    Skin melanoma is one of the most invasive types of skin cancer. It accounts for about 75% of all skin cancer deaths and has not yet been definitively treated. As a result, early diagnosis and prevention of the disease is important. Much research has been done to find ways to treat and cure cancer. One of the newest methods in this field is the use of nanotechnology to detect and inhibit cancer cells. In this study, the effect of using Nano microbubbles of Air, Oxygen and Ozone on A375 melanoma cancer cell line was evaluated.

    Materials and Methods

    A375 cell line treated with different concentrations of Nano microbubbles of Air, Oxygen and Ozone and were evaluated by MTT method. In order to measure cell viability, MTT plate was added to each well and then the plate was incubated.

    Results

    According to the results of this study, a decrease in the viability of A375 cancer cells with an increase in the concentration of Oxygen and Ozone Nano microbubbles after 24 hours indicates apoptosis and has a significant inhibition of the growth of these cells.

    Conclusion

    The results of this study indicate that Nano microbubbles of Oxygen and Ozone in high concentrations cause cell death of A375 cell line. The results of this study will help investigate the role of Nano microbubbles of Air, Oxygen and Ozone in the treatment of melanoma cancer.

    Background

    Auraptene is a coumarin derivative extracted from citrus species, such as lemon, grapefruit, and orange. To date, auraptene has shown antioxidant, antibacterial, anti-inflammatory, antiproliferative, antiapoptotic, and antitumor activities. Among these, antitumor activity has become more important over the recent years, while its underlying mechanism is not fully understood. The current study was conducted to evaluate the antiproliferative effect of auraptene and its mechanisms on MCF7 cell line.

    Method

    This experimental study investigated whether hesperidin affected the proliferation of MCF-7 human breast cancer cells. MCF7 cells were cultured in DMEM medium with 10% fetal bovine serum, 100 μg/ml streptomycin, and 100 units/ml penicillin. The cells were incubated in order to be treated with different concentrations of auraptene and time points. Subsequently, the amount of cytotoxicity and apoptosis was measured utilizing MTT and PI staining.

    Results

    The MTT assay revealed that auraptene had a significant effect on cell viability and induced apoptosis in MCF7 cells at concentrations of 75, 100, 130, 170, and 200 μM.

    Conclusion

    In this study, through the induction of apoptosis, auraptene prevented the growth and inhibited the proliferation of MCF7 cells at high concentrations in a dose-dependent manner. However, further investigation is needed to reveal the mechanisms of auraptene concerning apoptosis induction.

    In recent years, resistance to conventional antimicrobial drugs has become a serious concern in the clinic. Hence, the discovery of novel and effective antimicrobial agents with improved properties is of great value. In this study, the antibacterial and anticandidal activities of some imidazole, benzimidazole and benztriazole derivatives (C1-C8) against several species of Gram-positive and Gram-negative bacteria, including Staphylococcus aureus, Streptococcus pyogenes, Escherichia coli and Salmonella typhi as well as one species of fungi including Candida albicans, were evaluated using Clinical & Laboratory Standards Institute (CLSI) method. Antimicrobial evaluation revealed that among the tested compounds, imidazole derivative (C5) indicated the highest activity against bacterial strains and Candida albicans. It was found that compound C5 is more potent than ampicillin against S. aureus strain (MIC =2-16 µg/mL) and possessed excellent anticandidal activity (MIC =1 µg/mL) which was comparable to Amphotericin B as the positive control. In addition, cytotoxic activity of the tested compounds was investigated using MTT assay. The results of MTT assay demonstrated that the toxicity of the tested compounds was less than 35%.

    Cancers in terms of morbidity and mortality are one of the major universal issues. New compounds of anticancer agents based on β-aryl-β-mercapto ketones scaffold possessing piperidinyl ethoxy or morpholinyl ethoxy groups were synthesized and evaluated as cytotoxic agents. Cytotoxic effects of synthesized compounds were measured against MCF-7, human ER-positive breast cancer cell lines, using MTT assay. The results indicated that all compounds had high cytotoxic activity on MCF-7 cancerous cells, even more than the reference drug Tamoxifen. Among them, compounds 3-(4-(2-morpholinoethoxy)phenyl)-1-phenyl-3-(phenylthio)propan-1-one (4a) and 1-(4-methoxyphenyl)-3-(3-(2-morpholinoethoxy)phenyl)-3-(phenylthio)propan-1-one (4h) had no significant cytotoxic effects on normal cells compared to Tamoxifen. Our results also indicated that adding tertiary amine basic side chain, found in Tamoxifen drug, to 1,3-diphenyl-3-(phenylthio)propan-1-ones improves the cytotoxic effects of these compounds on breast cancer cells.

    Recently, fungal drug resistance has significantly increased especially in opportunistic fungus like Candida albicans. Accordingly, it is necessary to use more effective drugs with less toxicity and high influences. Among a large of investigations, ionic liquids showed biological influence and antimicrobial activities. The aim of this study was in vitro investigation of antifungal activity of pyridine –based ionic liquid on a standard strain of Candida albicans and evaluate its toxicity on host cells. A standard strain of Candida albicans was re- cultured on Sabouraud Dextrose Agar (SDA) containing chloramphenicol, incubated at 37℃ for 24 h. Antifungal effect of a novel ionic liquid ([Met-Hcl] [Pys] ), was evaluated using inhibitory zone diameter. The minimum inhibitory concentration (MIC) and minimum fungal concentration (MFC) were performed using micro dilution method. In continue MTT test were done to evaluate the toxicity of the liquid on host cells. The ionic liquid showed a good effect to prevent of Candida albicans growth. Inhibitory zone diameter was between 34±1 mm. The MIC evaluation was 708.4 ppm. Also the results of MTT test showed the viability of host cells at the 16 dilution. In conclusion, the results of this study manifested that the novel ionic liquid has a good antifungal activity against Candida albicans standard strain with low toxicity to human cells and probably can use as a good novel drug in treatment of candidiasis. Although the need for more studies is crystal clear.

    مقدمه

    پریمتامین و سولفادیازین بعنوان داروهای انتخابی برای عفونت توکسوپلاسما می باشند، اما وجود برخی عوارض جانبی باعث محدودیت در استفاده میشود. گسترش استفاده از نانوذرات در تحقیقات بیولوژیکی و اثبات اثرات موثر نانوذره منگنز روی قارچها و باکتریها، در کنار نبود اطلاعات کافی درباره اثر ضد توکسوپلاسمایی آن، انگیزه ای برای طراحی این مطالعه شده است. منگنز می تواند از طریق افزایش فعال سازی mRNA ژن FOXO3a-Bim/PUMA و فعالسازی کاسپاز-3، آپوپتوز سلول را القا میکند. این مطالعه با هدف بررسی اثر بخشی نانوذرات منگنز اکساید علیه توکسوپلاسما گوندی در شرایط برون تنی انجام شده است.

    روش کار

    برای ارزیابی فعالیت ضد توکسوپلاسمایی نانوذرات، از مشاهدات میکروسکوپ نوری برای تعیین تعداد انگلهای باقیمانده در هر چاهک استفاده شد. از آزمون MTT برای تعیین اثر سمی نانوذره منگنز اکساید روی تاکی زوییت توکسوپلاسما گوندی استفاده شد. آپوپتوز احتمالی توکسوپلاسما گوندی توسط نانوذرات منگنز اکساید با روش فلوسایتومتری مورد ارزیابی قرار گرفت.

    یافته ها

    مقدار IC50 نانوذرات منگنز اکساید در مقابل تاکی زوییت های توکسوپلاسما 105 میکروگرم بر میلی لیتر ارزیابی شد. همچنین با توجه به نمودار بقا و درصد بالای سلولهای ماکروفاژ زنده مانده در غلظت مورد نظر برای درمان، اثر سمی قابل توجهی از نانوذره روی ماکروفاژ مشاهده نشد. نتیجه بررسی فلوسایتومتری نیز بیانگر القای حدود 40% آپوپتوز در تاکی زوییتهای توکسوپلاسما گوندی است.

    نتیجه گیری

    نانوذرات منگنز اکساید دارای اثری موثر روی تاکی زوییت های توکسوپلاسما گوندی در شرایط برون تنی بوده و میتواند بعنوان یک کاندید درمانی برای این آلودگی در نظر گرفته شود.

    Introduction

    Pyrimethamine and sulfadiazine are selective medications for toxoplasmosis, but some side effects hinder their consumption. Increasing the use of nanoparticles in biological studies and showing the beneficial effects of manganese nanoparticles on fungi and bacteria, as well as the lack of sufficient knowledge on its anti-Toxoplasma impacts, was the motivation for the design of this study. Manganese can provoke cell apoptosis by increasing the activation of the FRXO3a-Bim/PUMA mRNA and caspase-3 pathway. The objective of this study was to investigate the efficacy of manganese oxide nanoparticles (Mn2O3 NPs) against Toxoplasma gondii (T. gondii) in vitro.

    Methods

    To assess the anti-Toxoplasma activity of Mn2O3 NPs, the light microscopic observation was applied to evaluate the number of residual parasites in each well. Then, the MTT method was used to specify the toxic effect of Mn2O3 NPs on T. gondii toxicity. Finally, the potential apoptosis of T. gondii by Mn2O3 NPs was investigated by flow cytometry assay

    Result

    The IC50 value of Mn2O3 NPs against T. gondii tachyzoite was 105 μg/ml. There was also no significant toxic effect of Mn2O3 NPs on macrophages due to the high percentage of surviving macrophages at the desired concentration for treatment. The findings of the flow cytometry revealed that about 40% of tachyzoites were caused to apoptosis with Mn2O3 NPs.

    Conclusion

    Mn2O3 NPs have a beneficial effect on T. gondii tachyzoite in vitro and could be regarded as a candidate for the treatment of this infection.
