### Detailed Description of the MIR626 Gene

**Gene Symbol:** MIR626

**Type:** MicroRNA (miRNA)

**Length:** Approximately 20-24 nucleotides in the mature form

#### 1. Associated Genes
MIR626 is known to target various genes involved in multiple signaling pathways and biological processes. Some notable associated genes and targets include:
- **TP53** (tumor protein p53) - Involved in cell cycle regulation and apoptosis.
- **PTEN** (phosphatase and tensin homolog) - A critical regulator of the cell cycle and apoptosis.
- **BCL2** (B-cell lymphoma 2) - Involved in regulating cell death (apoptosis).
- **SRC** (SRC proto-oncogene, non-receptor tyrosine kinase) - Involved in cellular signaling pathways.
  
Although there are numerous potential targets, research is ongoing to identify all the direct interactions of MIR626.

#### 2. Aging and Age-Related Diseases
MIR626 has been studied for its potential role in aging and age-related conditions. While specific pathways or mechanisms related to aging are still under investigation, it has been associated with processes such as:
