The INHCAP gene (Inhibitor of NF-kappa-B Kinase Complex Associated Protein) is known for its involvement in the regulation of various biological processes, particularly in relation to the NF-kappa-B signaling pathway, which plays a crucial role in inflammatory responses and cellular stress.

### 1. Associated Genes
While the INHCAP gene may not have an extensive list of directly associated genes that are universally acknowledged, it generally interacts with genes involved in the NF-kappa-B signaling pathway. Some notable genes that may be indirectly related or functionally interact with INHCAP include:

- **NFKB1**: A key component of the NF-kappa-B signaling pathway, which is associated with inflammation and immune response.
- **IKBKB** (IKKβ): Another important kinase that plays a role in the phosphorylation and degradation of IκB proteins, thereby permitting NF-kappa-B activation.
- Other downstream regulators or targets of NF-kappa-B, such as **TNF**, **IL6**, and **IL1B**, may also have relevant interactions.

### 2. Aging and Age-related Diseases
Currently, there is limited specific information linking the INHCAP gene directly with aging or age-related diseases. However, because it is involved in the NF-kappa-B signaling pathway, and given that this pathway has been implicated in various age-related inflammatory processes, there may be indirect associations with conditions such as:

- **Chronic Inflammatory Diseases**: Aging is generally associated with an increase in chronic low-grade inflammation, often referred to as "inflammaging."
- **Cancer**: The NF-kappa-B pathway plays a role in cell survival and proliferation, which may relate to cancer progression in the elderly.

Further research is needed to specifically delineate the role of INHCAP in these contexts.

### 3. Drug or Drug Classes
Currently, there is no extensive specific information listing any drugs or drug classes that directly target the INHCAP gene. However, as INHCAP is involved in the NF-kappa-B signaling pathway, drugs that modulate this pathway could be relevant. Some categories of drugs include:

- **Anti-inflammatory agents**: Such as corticosteroids, which might influence the NF-kappa-B signaling indirectly by affecting the inflammatory response regulated by this pathway.
- **Chemotherapeutics**: Some anticancer drugs may indirectly affect the activity of NF-kappa-B and thus could interact with the cellular processes where INHCAP is involved.

### 4. Pathways and Biological Processes
INHCAP is primarily involved in the following biological processes and pathways:

- **NF-kappa-B Signaling Pathway**: Inhibition or regulation of NF-kappa-B activity affects various immune response mechanisms and inflammatory pathways.
- **Regulation of Apoptosis**: INHCAP may contribute to the modulation of cell survival and apoptosis through the NF-kappa-B pathway.
- **Cellular Response to Stress**: The handling of cellular stress responses may involve INHCAP by affecting the stress-activated pathways.

In summary, the INHCAP gene plays a significant role in cellular signaling through its involvement in the NF-kappa-B pathway. Although there are aspects of its association with aging and disease that warrant further investigation, its functional interactions primarily position it within the broader context of inflammation and immune response regulation. For updated and more specific associations, recent literature should be consulted to include any new findings since my last training data cutoff in October 2023.
