The ENO1P1 gene is a pseudogene related to the ENO1 gene, which encodes the enzyme enolase. ENO1P1 is situated in the human genome and shares high sequence similarity with the functional ENO1 gene, but its biological function remains poorly understood as it is classified as a pseudogene, typically lacking the ability to encode a functional protein.

### 1. Associated Genes:
Though specific associations are not widely detailed in the literature for ENO1P1, it can be inferred that it shares sequence similarity and potential regulatory interactions with its parent gene, ENO1. Pseudogenes like ENO1P1 might engage in regulatory roles affecting gene networks involving:

- **ENO2**: This gene encodes another enolase and could share functional pathways with ENO1.
- **ENO3**: Similar to ENO1 and ENO2, ENO3 is involved in glycolysis and may have interactions with ENO1P1 in some regulatory capacity.

### 2. Aging and Age-Related Diseases:
While specific information linking ENO1P1 directly to aging or age-related diseases is limited due to its status as a pseudogene, the functional ENO1 gene has implications in cellular metabolism, which is fundamental in aging processes. Dysregulation of metabolic pathways can influence age-related diseases such as cancer, neurodegeneration, and metabolic syndromes. The role of ENO1 in tumor metabolism may indirectly relate to aging, but further research is necessary to elucidate any direct effects of ENO1P1 related to aging mechanisms.

### 3. Drug Interactions:
Currently, there are no specific drugs or drug classes documented that interact directly with the ENO1P1 gene, primarily because it is a pseudogene and does not produce a functional protein. However, compounds that target the enolase family (like ENO1) might theoretically have indirect effects that could influence pathways associated with ENO1P1 due to their sequence relation.

### 4. Pathways and Biological Processes:
As a pseudogene, ENO1P1 does not have documented direct involvement in biological pathways. However, it is important to consider the following biological processes associated with its functional counterpart, ENO1:

- **Glycolysis**: ENO1 plays a crucial role in the glycolytic pathway, which is vital for cellular energy production.
- **Metabolic Processes**: Being involved in energy metabolism links ENO1P1 to various metabolic pathways, given the shared sequence with ENO1.
- **Cancer Metabolism**: The ENO1 gene is often upregulated in cancer cells, suggesting that its homologous pseudogene might have indirect implications in tumor-related metabolic adjustments.

### Conclusion
ENO1P1 is a pseudogene associated with the ENO1 gene, reflecting the complexity of gene functions and regulatory mechanisms in genomics. Further research is needed to unveil its potential roles, especially in the context of health, aging, and disease.
