Identification of Interorganelle Crosstalk Effect on Various Diseases, Including Kidney Disease: A Systematic Review and Meta-analysis

Context:

 Subcellular organelles communicate with each other via their metabolites and maintain different cellular functions. They contain nucleus, mitochondria, endoplasmic reticulum, peroxisomes, and lysosomes.

 This study aimed to identify interorganelle communication (crosstalk) in physiopathological states of cells in health and disease.

Data Sources:

 The databases including PubMed Central, Embase, Scopus, and Google Scholar were searched to extract data. For statistical analyses, percentage, relative risk, and odds ratio were used. Moreover, the risk of bias was assessed by Cochrane collaboration’s tool.

 Out of 20 studies included in this research, 12 (60%) studies included mitochondria-endoplasmic reticulum communication, 4 (20%) studies mitochondria-lysosome communication, 2 (10%) studies mitochondria-peroxisome, and 2 (10%) studies mitochondria-nucleus. Interorganelle crosstalk between mitochondria and peroxisome or lysosome had risk and odds of 1.5 (effect) on aging and age-related disorders. There were no effects of mitochondrial communication with other organelles on certain pathologies. The relative risk of mitochondria to nucleus crosstalk on apoptosis was assessed 1.13, and relative risk of mitochondria to lysosome crosstalk was assessed 2. In addition, the odds ratio of mitochondria to lysosome crosstalk on apoptosis was assessed 5, indicating a large effect on this crosstalk.

 Recent expansion of pharmacological, molecular, and genetic tools indicated these organelles have active intracellular and extracellular communications, which is important for cells and organ homeostasis. Disruption of such communication has been associated with aging and age-related disorders in this research.
