**FTCD-AS1 Gene Overview:**

The FTCD-AS1 gene (Folate Tunnel Decarboxylase Antisense RNA 1) is a long non-coding RNA (lncRNA) located on chromosome 1. As an antisense RNA, it is thought to function in regulating the expression of its associated protein-coding genes through mechanisms such as transcriptional interference or silencing.

### 1. Associated Genes
While the specific NCBI and UniProt summaries may not provide an exhaustive list of associated genes, FTCD-AS1 is known to be located near or associated with the **FTCD** gene (Folate Decarboxylase, a coding gene involved in folate metabolism). Other genes that may be indirectly associated through regulatory networks or expression patterns include:
- **MTHFR** (Methylenetetrahydrofolate reductase)
- **DHFR** (Dihydrofolate reductase)
- **SLC19A1** (Solute carrier family 19 member 1)

### 2. Aging and Age-Related Diseases
There is limited specific information available regarding FTCD-AS1's direct role in aging or age-related diseases. However, given its involvement in folate metabolism, it might have indirect relationships with:
- **Cardiovascular diseases**: Folate levels are often linked with homocysteine levels, which are associated with cardiovascular health.
- **Cognitive decline**: There is some evidence suggesting that folate may play a role in neuroprotection and cognitive function, where alterations in folate metabolism could contribute to cognitive aging.
- **Cancer**: Aberrant folate metabolism is known to be associated with certain cancers, and as lncRNAs like FTCD-AS1 can influence gene expression, it may have implications for tumorigenesis or cancer progression.

### 3. Drug Interactions
Currently, there are no specific drugs or drug classes directly known to target or interact with the FTCD-AS1 gene. However, given its role in folate metabolism, one could theorize that drugs affecting folate levels (such as methotrexate, a folate antagonist used in cancer therapy and autoimmune diseases) could indirectly affect the expression or function of FTCD-AS1.

### 4. Pathways and Biological Processes
FTCD-AS1 is implicated in several biological processes, largely due to its relationship with folate metabolism. Key pathways and processes include:
- **Folate metabolism**: As an involved factor near the FTCD gene, it may play roles in pathways related to the cycling of tetrahydrofolate compounds.
- **Cell proliferation and differentiation**: Given that folate is crucial for DNA synthesis and repair, FTCD-AS1 may influence cellular growth processes.
- **Epigenetic regulation**: lncRNAs are often involved in modulating chromatin structure and gene expression patterns, hinting at a potential role in gene regulatory networks, particularly in developmental and physiological processes.

In summary, while there may be limited detailed information on FTCD-AS1 in the context of age-related diseases, its connection to essential metabolic pathways suggests it could have significant biological implications. Further research into the specific interactions, mechanisms, and potential clinical relevance of FTCD-AS1 is warranted.
