### CCDC28A-AS1 Gene Overview

The CCDC28A-AS1 gene is classified as a long non-coding RNA (lncRNA) and is positioned in the antisense orientation to the CCDC28A gene. As indicated in the provided summaries, it has been described as a dubious gene prediction, suggesting that its biological significance may not be fully understood or characterized. Given that it is an antisense RNA, it may play a role in regulating the expression of its sense counterpart, CCDC28A, although specific functional roles have not been well defined.

#### 1. Associated Genes
While specific associations aren't usually listed in basic gene summaries, genes that commonly have related functions or are located in proximity to CCDC28A-AS1 may include those involved in similar regulatory networks or biological pathways. Unfortunately, detailed lists in databases may not be comprehensive. However, potential candidates might include:
- **CCDC28A** (the sense counterpart).
- **Other lncRNAs** that interact with CCDC28A or are co-expressed with it in particular tissues.

Further investigation through interaction databases such as STRING or BioGRID may yield additional association data.

#### 2. Aging and Age-Related Diseases
As CCDC28A-AS1 is classified as a dubious gene prediction, explicit associations with aging or age-related diseases are not well established in the literature. However, some long non-coding RNAs have been implicated in processes such as cellular senescence, transcriptional regulation during aging and modulation of inflammation. For a precise understanding, a literature search focusing on lncRNAs and their roles in aging and disease processes could yield more information, but any direct link of CCDC28A-AS1 would require substantial evidence currently not available.

#### 3. Drug Interactions
As of now, there is no known information on specific drugs or drug classes that directly interact with CCDC28A-AS1. Long non-coding RNAs may indirectly affect pharmacological responses, but this area of research is still emerging. More targeted investigations using bioinformatics tools like DrugBank or STITCH can help identify potential indirect interactions based on co-expression or common pathways.

#### 4. Pathways and Biological Processes
Due to its classification as a long non-coding RNA, CCDC28A-AS1 may be involved in various biological processes, although specific pathways have not been clearly defined. Non-coding RNAs are known to participate in:
- **Gene regulation**: They can interact with transcription factors and chromatin remodeling complexes.
- **Epigenetic regulation**: Some lncRNAs influence the methylation and acetylation status of histones, thereby affecting gene expression.
- **Cell cycle regulation**: They may play roles in the control of the cell cycle and cellular proliferation.

For precise information regarding any known pathways, databases like KEGG, Reactome, or pathway commons can be consulted for insights into associated biological processes.

### Conclusion
CCDC28A-AS1 is a lesser-studied lncRNA with unclear biological significance and potential associations with aging and drug interactions that remain to be more thoroughly explored. Further research is required to elucidate its functions and any clinical implications it may have.
