### EHD4-AS1 Gene Overview

The EHD4-AS1 gene is classified as a non-coding RNA and is an antisense transcript associated with the EHD4 gene. The precise role of EHD4-AS1 is still being elucidated, but as an antisense RNA, it may have regulatory functions influencing the expression of the EHD4 gene and potentially affecting other genes in the surrounding genomic region.

### 1. Associated Genes

While the summaries provided by NCBI and UniProt may not list specific associated genes, EHD4-AS1 is likely to have interactions or associations with:
- **EHD4 (EHD Protein 4)**: The main gene for which EHD4-AS1 is the antisense RNA.
- Other genes possibly involved in the same pathways or biological processes.

Further studies may reveal interactions with downstream targets regulated directly or indirectly by EHD4 or by pathways in which EHD4 is involved.

### 2. Aging and Age-Related Diseases

As of October 2023, specific literature detailing the role of EHD4-AS1 in aging or age-related diseases is limited. However, its counterpart, EHD4, is involved in cellular processes like endocytosis and membrane trafficking, which can have implications in cellular aging and age-related diseases. Dysregulation of endocytic processes has been associated with neurodegenerative diseases, metabolic disorders, and other conditions related to aging. Future research may help clarify any direct implications of EHD4-AS1 in these contexts.

### 3. Drug or Drug Classes Interaction

Currently, there is no specific information available regarding drugs or drug classes that directly target or interact with EHD4-AS1. However, being involved in regulatory processes, changes in the expression levels of EHD4-AS1 due to certain pharmacological agents might indirectly influence the processes associated with EHD4.

Continued exploration of regulatory RNAs and their role in gene expression may uncover more on this front.

### 4. Pathways and Biological Processes

- **Endocytosis and Membrane Trafficking**: Given its association with the EHD4 gene, which plays a role in endocytic recycling pathways, EHD4-AS1 may also be involved in these biological processes.
- **Cellular Response to Nutrients**: As part of pathways outlining the cellular response to stressors, nutrient sensing could also involve EHD4.
  
Overall, EHD4-AS1 may participate in various cellular regulatory mechanisms through its interaction with EHD4 and potentially through modifying the expression levels of other genes, adding an additional layer of complexity to gene regulation within those pathways.

As with any gene, ongoing research will continue to refine our understanding of EHD4-AS1’s roles and its broader implications in health and disease contexts.
