The expression of TLRs in testicular cancer: A case control study
Author(s):
Abstract:
Background
It has been suggested that malfunction of immune system may cause testicular cancer. Recently, our understanding of innate immune system has been expanded, by discovery of “Toll- like receptors” (TLRs). Some studies have shown that polymorphisms of TLR2 and 4 can effect on the risk of cancer. Also, the role of TLRs 3and 9 have been shown in apoptosis of cancer cells and metastasis in animal models.Objective
Little information is available about the influence of innate immunity on testicular malignancy. Therefore, expression of TLRs 2, 3, 4 and 9 as main components of innate immunity has been investigated in this study.Materials And Methods
In this case control study, TLRs gene expression was examined by RT-PCR in normal testis and testicular cancer tissues. Real time quantitative PCR (Q-PCR) analysis was used to compare the relative expression of TLRs between the samples.Results
mRNAs of TLR 2, 3, 4 and 9 were expressed in all normal and cancer samples. Q-PCR reveals that cancer samples had stronger expression of these genes in compared with normal ones.Conclusion
It seems that the different TLRs expression in testicular cancer cells may contribute to extensive signaling pathways involved in carcinogenesis.Keywords:
