Abstract:
Cellular senescence is a program activated in normal cells in response to various types of stresses and is manifested by permanent arrest of cell cycle. Cellular senescence is closely related to tumor suppression, and may contribute to the ageing of organisms. The complex senescence cell phenotype has many different mechanisms. Recent studies have provided important insights regarding the role played by miRNAs during cellular senescence as a novel molecular mechanism. In this article, we will review the latest advances in the identification and validation of senescence-regulatory miRNAs and the possible mechanisms.
Insights
Cellular senescence, a permanent cell cycle arrest, is linked to aging and tumor suppression. MicroRNAs (miRNAs) are emerging as key regulators of this complex process, offering new insights into senescence mechanisms.

- It plays roles in tumor suppression and organismal aging.
- The molecular mechanisms underlying senescence are complex and multifaceted.
Purpose of the Study:
- To review recent advances in understanding the role of microRNAs (miRNAs) in cellular senescence.
- To discuss the identification and validation of miRNAs that regulate senescence.
- To explore the potential mechanisms by which miRNAs influence senescence.
Main Methods:

siRNA - Small Interfering RNAs
In the cytoplasm, siRNA is processed from a double-stranded RNA, which comes from either endogenous DNA transcription or exogenous sources like a virus. This double-stranded RNA is then cleaved by the ATP-dependent...
