### MIR138-2 Gene Overview

**Gene Symbol:** MIR138-2

**Function:** MIR138-2 encodes a microRNA (miRNA) involved in the post-transcriptional regulation of gene expression. miRNAs, including those derived from MIR138-2, can modulate both mRNA stability and protein translation, playing a critical role in various biological processes.

### 1. Associated Genes
MIR138-2 is known to have potential interactions with several target genes, primarily through its regulatory functions. While specific genes may vary across studies, some associated genes could include:

- **SOX2** - a transcription factor involved in pluripotency.
- **Rho-associated kinase 1 (ROCK1)** - involved in cytoskeletal dynamics and cellular processes.
- **PTEN** - a tumor suppressor gene that regulates cell growth.
- **RELA** - a subunit of the NF-kB transcription factor, which plays a role in inflammation and immune responses.

The biological targets of MIR138-2 can contribute to cancer progression, neurogenesis, and other developmental processes.

### 2. Aging and Age-Related Diseases
Research has indicated that MIR138-2 may be involved in aging-related phenomena and conditions:

- **Neurodegenerative Diseases:** Altered expression of MIR138-2 has been implicated in neurodegenerative disorders such as Alzheimer's disease, suggesting a role in synaptic plasticity and neuron integrity.
- **Cellular Senescence:** miRNAs, including MIR138-2, may have regulatory roles in cellular aging and senescence, potentially impacting processes related to tissue repair and regeneration.
- **Cognitive Decline:** The dysregulation of MIR138-2 has been associated with cognitive decline, possibly through its interaction with genes controlling neurogenesis and synaptic function.
