Purpose:
This research aimed to analyze alterations in microRNA expression in the diseases POF (Premature Ovarian Failure), PCOS (Polycystic Ovarian Syndrome), and ovarian cancer in order to understand the molecular changes associated with these conditions. The findings could potentially be utilized for diagnostic, therapeutic, predictive, and preventive purposes. Furthermore, the impact and role of microRNAs in each ailment, along with their functional pathways, were elucidated and examined.
Methods:
In this study, the genes involved in the disease were studied, and then the miRNAs that targeted these genes were evaluated, and finally the signaling and functional pathways of each of the miRNAs were assessed. In this process, genetic databases and previous studies were carefully assessed.
Results:
miRNAs are short nucleotide sequences that belong to the category of non-coding RNAs. They play a crucial role in various physiological activities, including cell division, growth, differentiation, and cell death (necrosis and apoptosis), miRNAs are involved in various physiological processes Such alterations are common in various diseases, including cancer. miRNAs are involved in various physiological processes, such as folliculogenesis and steroidogenesis, as well as in pathological conditions such as POF, PCOS, and ovarian cancer. They have powerful regulatory effects and controlling the most activities of normal and pathological cells. While microRNAs (miRNAs) play a significant role in normal ovarian functions, there are reports of their expression changes in PCOS, ovarian cancer, and POF.
Conclusions:
miRNAs have been found to exert significant influence on both physiological and pathological cellular processes. Understanding the dynamic patterns of miRNA alterations can provide valuable insights for researchers and therapists, enabling them to utilize these biomarkers effectively in diagnostic, therapeutic, and preventive applications.
