The LINC01387 gene is a long intergenic non-coding RNA (lincRNA) and is characterized as a product of dubious gene prediction, suggesting that its functional role might not be well established or could be speculative at this point.

### 1. Associated Genes:
LINC01387 has been connected to various genes, although specific details may vary based on ongoing research. Commonly associated genes in the broader context of long non-coding RNAs often involve regulatory networks and may include protein-coding genes involved in similar biological pathways. While explicit associations are not frequently highlighted in databases for LINC01387, it may be involved in regulatory relationships with oncogenes or tumor suppressor genes based on its context of expression in certain tissues. Further research is required to draw definitive links to specific genes.

### 2. Aging and Age-related Diseases:
Currently, specific associations of LINC01387 with aging or age-related diseases have not been clearly established in scientific literature or databases. However, lincRNAs are generally studied in the context of various diseases, including cancer and neurodegenerative disorders, which may have age-related components. There may be indirect associations via roles in cellular senescence or modulating pathways involved in cellular maintenance and stress response, but more targeted research would be necessary to clarify these connections for LINC01387 specifically.

### 3. Drug Interactions:
As of now, there are no known drugs or drug classes that have documented interactions with the LINC01387 gene. Research into the targeted roles of lincRNAs in drug development is emerging, but specific pharmacological linkages for LINC01387 are not yet established in the literature.

### 4. Pathways and Biological Processes:
While LINC01387 might be involved in several biological pathways typical of lincRNAs, explicit pathways associated with LINC01387 are not widely reported. LincRNAs are often implicated in various cellular processes such as gene regulation, chromatin remodeling, and serving as molecular scaffolds. Investigating the role of LINC01387 in specific cellular and molecular functions would require targeted research to elucidate its pathway involvements.

### Summary:
The LINC01387 gene is categorized as a dubious gene with limited available characterization regarding its functions, connections to aging and age-related diseases, drug interactions, and specific biological pathways. As with many lincRNAs, ongoing research may uncover novel roles and associations that can better define its importance in biological processes or pathologies.
