The WWC1 gene, also known as the "WW and C2 domain-containing protein 1," encodes a cytoplasmic phosphoprotein with essential roles in various signaling pathways and biological processes. Here’s an in-depth overview based on your request:

### 1. Associated Genes
While the provided summaries mention interactions with specific genes such as **PRKCZ** (protein kinase C zeta) and **NF2** (neurofibromatosis type 2), WWC1 may also be associated with the following genes:

- **LATS1 and LATS2**: As mentioned, these are serine/threonine kinases involved in the Hippo signaling pathway, which is crucial for regulating cell proliferation and apoptosis.
  
- **ESR1** (Estrogen Receptor 1): This gene is significant in the context of estradiol-mediated transcriptional regulation, which WWC1 coactivates.

- **DYNLL1**: A light chain protein of dynein that participates in various cellular functions, with implications in intercellular transport.

### 2. Aging and Age-Related Diseases
Although specific studies directly linking WWC1 to aging or age-related diseases are limited, its role in the Hippo signaling pathway and cognitive functions suggests potential implications:

- **Cognitive Decline**: Since WWC1 is involved in memory performance, its dysregulation could potentially impact neurodegenerative conditions like Alzheimer's disease.
  
- **Cancer**: Considering that the Hippo pathway is pivotal in tumor suppression, mutations or aberrations in WWC1 may contribute to age-related cancers, where cell proliferation regulation becomes increasingly important.

### 3. Drug Interactions
There is currently no direct listing of specific drugs or drug classes that interact selectively with WWC1 in typical databases. However, because WWC1 is part of the Hippo signaling pathways, it may be indirectly influenced by drugs targeting related pathways, such as:

- **Therapeutics for Cancer**: Drugs influencing apoptosis or cell proliferation may indirectly affect WWC1 activity, given its role in tumor suppression.

- **Neuroactive Drugs**: Since WWC1 affects cognitive functions, neuroactive agents may modulate its expression or activity, enhancing memory and cognitive performance.

### 4. Pathways and Biological Processes
WWC1 is primarily involved in the following pathways:

- **Hippo Signaling Pathway**: A critical pathway for regulating organ size by controlling cellular growth, apoptosis, and stem cell behavior.

- **Regulation of Transcription**: Acts as a transcriptional coactivator for ESR1, linking it to hormonal signaling pathways.

- **Mitogen-Activated Protein Kinase (MAPK) Signaling Pathway**: Modulates the ERK/MAPK cascade, a pathway essential for cellular responses to growth factors and stress.

- **Cell Migration and Adhesion**: Plays a role in the directional migration of podocytes, which are crucial for kidney function and implications in kidney diseases.

- **Memory and Cognitive Functions**: The role in memory enhancement links WWC1 to neurological processes, making it significant in the understanding of cognitive diseases.

### Conclusion
The WWC1 gene is involved in critical signaling pathways such as the Hippo pathway and has implications in cognition, potentially linking it to aging and neurodegenerative diseases. Its interaction with key proteins enhances its significance in both cellular processes and therapeutic developments. Further research may elucidate its direct connections to aging and specific drug interactions.
