### Overview of the RNU4-87P Gene

**Gene Symbol**: RNU4-87P

**Gene Type**: The RNU4-87P gene is classified as a non-coding RNA gene, specifically a small nuclear RNA (snRNA). 

### 1. Associated Genes

RNU4-87P is a member of the small nucleolar RNA (snoRNA) family, involved in the modification and processing of ribosomal RNA, and is classified as a member of the U4 small nuclear RNA family. While specific associations with other genes may not be detailed in standard databases, snoRNAs like RNU4-87P can influence gene expression by modulating the availability and functioning of associated proteins in ribonucleoprotein complexes. Furthermore, gene interactions may occur indirectly; for instance,

- **RNU4-1**: A gene closely related to the structure and function of RNU4-87P, belonging to the same family.
- **RNU4-10**: Another gene in the same snoRNA class that might have overlapping functions and regulatory pathways.

### 2. Aging or Age-Related Diseases

There is limited direct evidence connecting the RNU4-87P gene with aging or age-related diseases in the current literature. However, snRNA dysregulation, in general, has been implicated in various age-related cellular processes, including:

- RNA splicing and processing errors which could lead to decreased protein function and accumulation of damaged proteins.
- Potential implications in neurodegenerative diseases, as the role of small RNAs is critical in the maintenance of neuronal function.

If newer studies have emerged post-2023 connecting RNU4-87P specifically to age-related diseases, these would be found in more recent databases or publications.

### 3. Drug Interactions

Currently, there are no specific drugs or drug classes known to interact directly with the RNU4-87P gene. In general, snoRNAs and snRNAs, such as RNU4-87P, are not typical drug targets. However, they could have relevance in contexts:

- **Gene therapies**: Future prospects where modulation of non-coding RNAs may serve therapeutic purposes.
- **Antisense oligonucleotides**: Could potentially be developed to modulate the expression of non-coding RNAs like RNU4-87P in various contexts.

### 4. Pathways and Biological Processes

RNU4-87P is involved in several biological processes, primarily linked to RNA metabolism, including:

- **RNA processing**: Specifically, the assembly and maturation of the spliceosomal complex and the modification of other small nuclear RNAs.
- **Spliceosome formation**: The gene contributes to the function of the spliceosome, a complex responsible for the removal of introns from pre-mRNA.
- **Regulation of gene expression**: Although the gene itself does not encode proteins, its role in RNA processing indirectly influences gene expression levels.

### Conclusion

The RNU4-87P gene, as a small nuclear RNA, is integral to processes of RNA modification and splicing, although direct links to aging, disease, or drug interactions are less characterized. The exploration of non-coding RNAs is an expanding field, and ongoing research may uncover more significant associations, particularly regarding age-related conditions and potential therapeutic strategies.
