The **KRT18P61** gene is a pseudogene, which means it is a segment of DNA that resembles a gene but is non-functional in terms of coding for a protein. The designation **KRT18P** indicates that it is related to the keratin family. Keratins are a group of fibrous structural proteins that are critical for the integrity and resilience of epithelial cells.

### 1. Associated Genes
While KRT18P61 itself is a pseudogene and may not have many direct associations, it is part of the larger keratin gene family, which includes other keratin genes such as:
- **KRT18** (Keratin 18)
- **KRT8** (Keratin 8)
- **KRT14** (Keratin 14)
- **KRT19** (Keratin 19)

These keratins are involved in structural support and are usually associated with various epithelial tissues.

### 2. Aging and Age-Related Diseases
KRT18P61, being a pseudogene, does not have established direct roles in aging or age-related diseases associated with functional genes. However, the keratin family as a whole, especially keratin 18, has been studied in the context of:
- **Liver fibrosis and hepatocellular carcinoma**: Altered expression of keratins is seen in liver diseases, which may be influenced by aging.
- **Skin aging**: Changes in keratin expression can affect skin integrity and function, and altered keratin levels are noted in aging.
- **Cancer**: As keratin genes are involved in cell integrity, mutations or altered expression may have implications in cancer progression and metastasis.

### 3. Drug Interactions
No specific drugs or drug classes are known to directly interact with KRT18P61, as it is a pseudogene. However, potential research in anticancer drugs and therapies that may target the pathways involving functional keratins (e.g., KRT18) could have indirect implications. Given that keratin 18 can be a marker in various cancers, drugs affecting those pathways could be considered relevant.

### 4. Pathways and Biological Processes
KRT18P61 does not participate in any pathways or biological processes due to its pseudogene status. However, its functional counterparts (like KRT18) are involved in several key cellular processes, including:
- **Cytoskeletal organization**: Keratins provide structural integrity to cells.
- **Apoptosis**: Specific keratins are involved in apoptosis, helping to regulate programmed cell death.
- **Cellular adhesion**: They play a role in maintaining cell adhesion properties in epithelial tissues.

In summary, KRT18P61 is a pseudogene related to keratin genes that does not encode functional proteins or actively participate in biological pathways. However, its association with non-functional counterparts in the keratin family can provide contextual relevance in the study of diseases, aging, and potential therapeutic interventions.
