### MIR4281 Gene Overview

**Gene Symbol**: MIR4281  
**Gene Type**: MicroRNA (miRNA)  
**Length**: Approximately 20-24 nucleotides (nt) in mature form  

MIR4281 is part of a class of non-coding RNA molecules known as microRNAs, which play critical roles in the post-transcriptional regulation of gene expression. Through various mechanisms, such as base pairing with target mRNAs, miRNAs like MIR4281 modulate protein synthesis and mRNA stability.

### 1. Associated Genes
Other genes that are associated with MIR4281 include:
- **PTEN**: A tumor suppressor gene that is known to be targeted by various miRNAs, including MIR4281, in the context of cancer.
- **Ras Pathway**: Various genes involved in the Ras signaling pathway may be indirectly regulated by MIR4281 through its effects on target mRNAs crucial for oncogenesis.
  
Researchers have found links between MIR4281 and a range of other target genes, often specific to tissue types or pathological conditions.

### 2. Aging and Age-Related Diseases
MicroRNAs, including MIR4281, are increasingly studied in the context of aging and age-related diseases. Notable points include:
