The USP6NL-AS1 gene is a long non-coding RNA (lncRNA) that is associated with various regulatory functions in gene expression and cellular processes. As of my last training cut-off in October 2023, here are details regarding the USP6NL-AS1 gene as you requested:

### 1. Associated Genes
The USP6NL-AS1 gene has been linked with several other genes, although specific associations can vary based on different studies. Associations may include:
- **USP6**: The USP6NL-AS1 gene is located adjacent to the ubiquitin-specific protease 6 (USP6), indicating a regulatory relationship.
- **HLA Genes**: Some studies have indicated associations with human leukocyte antigen (HLA) genes due to shared regulatory networks.
- **Other lncRNAs and protein-coding genes**: The gene may be co-expressed with other lncRNAs and mRNAs involved in similar pathways, although specific genes would require more detailed databases or literature review for precise identification.

### 2. Aging and Age-Related Diseases
While specific information on USP6NL-AS1’s role in aging or age-related diseases may be limited, long non-coding RNAs like USP6NL-AS1 have been shown to play significant roles in cellular aging and senescence:
- **Cell senescence**: Some long non-coding RNAs have been implicated in the regulation of senescence-associated pathways, which could suggest a functional role for USP6NL-AS1 in aging.
- **Cancer**: Overexpression of certain lncRNAs, including USP6NL-AS1, has been correlated with age-related diseases, particularly various cancers, indicating potential involvement in tumor progression or suppression as organisms age.

### 3. Drug Interactions
As of now, specific drugs or drug classes with well-documented interactions with USP6NL-AS1 are not thoroughly characterized. However, some lncRNAs, including USP6NL-AS1, are of interest in drug development for cancer therapeutics, as inhibiting or modulating the expression of certain lncRNAs could provide a target for therapeutic intervention. Research is ongoing to elucidate specific interactions.

### 4. Pathways and Biological Processes
USP6NL-AS1 is implicated in several biological processes and pathways:
- **Gene Regulation**: As a long non-coding RNA, it likely plays a role in the regulation of various genes, either by interaction with transcription factors or by influencing chromatin remodeling.
- **Cell Cycle Regulation**: It may be involved in cell cycle processes, similar to other lncRNAs, contributing to proliferation or apoptosis.
- **Cancer Pathways**: Data suggest potential involvement in oncogenic pathways, particularly in the context of different cancers.
- **Immune Response**: There may be influences over immune-related processes, linked to its associations with specific pathways involving HLA genes.

To gain better insights into the USP6NL-AS1 gene, I would recommend consulting specialized databases such as Ensembl, GeneCards, or focused literature reviews on the role of lncRNAs in specific biological contexts, especially concerning aging and disease associations.
