Article Synopsis
  • Cellular senescence is a permanent stop in cell growth that occurs when cells can no longer divide, contributing to age-related diseases like prostate cancer.
  • Non-coding RNAs (ncRNAs), such as miRNAs and lncRNAs, are important for regulating gene expression, but their role in cellular senescence is not fully understood.
  • Research on human prostate epithelial cells showed that specific ncRNAs, particularly miR-335-3p and H19, are key players in cell cycle regulation and DNA repair, indicating their potential as biomarkers or therapeutic targets for age-related issues in prostate cancer.

In systems biology, inference of functional associations among genes is compelling because the construction of functional association networks facilitates biomarker discovery. Specifically, such gene associations in human can help identify putative biomarkers that can be used as diagnostic tools in treating patients. Although biomedical literature is considered a valuable data source for this task, currently only a limited number of webservers are available for mining gene-gene associations from the vast amount of biomedical literature using text mining techniques.

Background: Cellular homeostasis is regulated by the intricate interplay between a plethora of signaling pathways and "energetic sensors" in organs. In order to maintain energy balance, induction or repression of metabolic pathways must be regulated and act in concert with the energetic demands of the cell at a given point in time. A new class of small noncoding RNAs, the microRNAs (miRNAs), has added yet further complexity to the control of metabolic homeostasis.

It is estimated that 30% of all genes in the mammalian cells are regulated by microRNA (miRNAs). The most relevant miRNAs in a cellular context are not necessarily those with the greatest change in expression levels between healthy and diseased tissue. Differentially expressed (DE) miRNAs that modulate a large number of messenger RNA (mRNA) transcripts ultimately have a greater influence in determining phenotypic outcomes and are more important in a global biological context than miRNAs that modulate just a few mRNA transcripts.
