The RASSF4 gene (Ras association domain family member 4) is a member of the RASSF family, which is characterized by the presence of Ras association domains. Here's a detailed overview of RASSF4, including ancillary information based on your queries:

### 1. Associated Genes:
While RASSF4's primary interactions may not have been explicitly detailed in the summaries provided, it is likely to associate with other members of the RASSF family, including:
- **RASSF1:** Known for its role in tumor suppression.
- **RASSF2:** Also implicated in cellular processes like apoptosis and cell cycle regulation.
- **RASSF3:** Involved in the regulation of cell proliferation and death.
- **RASSF5 (also known as NORE1A):** Functions in a similar tumor suppressor capacity.
- **KRAS:** RASSF4 may act as an effector protein for KRAS, thus implicating RASSF4 in pathways linked to KRAS signaling.

### 2. Aging and Age-Related Diseases:
Currently, specific research directly linking RASSF4 to aging or age-related diseases is limited. However, considering its proposed role as a potential tumor suppressor and its involvement in apoptosis, there could be indirect associations. Tumorigenesis is often linked to age, and alterations in genes associated with apoptosis and cell cycle control can contribute to age-related cancer development. Therefore, while no definitive information specifically tying RASSF4 to aging has been established, its functional roles suggest it may play a part in age-related tumorigenesis.

### 3. Drug Interactions:
As of the latest data up to October 2023, there are no specific drugs or drug classes directly associated with RASSF4 that have been definitively documented in the scientific literature. However, given that it is proposed to function as a tumor suppressor and may be involved in mechanisms of apoptosis, drugs that target apoptotic pathways, cancer therapies, or those affecting KRAS pathways could indirectly relate to RASSF4.

### 4. Pathways and Biological Processes:
RASSF4 is involved in several significant biological pathways, including but not limited to:
- **Apoptosis Pathway:** RASSF4 may promote programmed cell death, which is crucial for preventing tumor development.
- **Cell Cycle Regulation:** It may contribute to mechanisms regulating the cell cycle, leading to cell cycle arrest under certain conditions.
- **Ras Signaling Pathways:** RASSF4 may act as an effector protein for KRAS, implicating it in downstream Ras signaling events crucial for cell differentiation and growth.
- **Tumor Suppression:** Its potential as a tumor suppressor links it to pathways involved in inhibiting tumor development.

In summary, while many aspects of RASSF4's function remain to be elucidated, its possible roles in apoptosis, cell cycle regulation, and interactions with other oncogenic pathways position it as a significant player in cancer biology and potentially in the biology of aging through its involvement in tumor suppression and related processes. Further research is needed to clarify its specific functions and associations.
