**RNA5SP155 Gene Overview:**

- **Gene Symbol:** RNA5SP155
- **Description:** RNA5SP155 is a gene that encodes a small nucleolar RNA (snoRNA). SnoRNAs are primarily involved in the modification and processing of other RNA molecules, particularly ribosomal RNA (rRNA), by guiding required modifications to these critical RNAs.

### 1. Associated Genes:
While specific associations beyond the provided summaries may not be well-documented, snoRNAs like RNA5SP155 often function in the context of larger RNA processing pathways and may be indirectly associated with several other ribosomal or RNA-related genes. Some relevant families of genes may include those involved in ribosome biogenesis, methyltransferase genes, and other snoRNA genes, which may work together to regulate the processing and modification of rRNAs.

### 2. Age-related Details:
While specific research directly linking RNA5SP155 to aging or age-related diseases may not be comprehensive in the literature, snoRNAs like RNA5SP155 can play important roles in cellular machinery that impacts aging processes. Alterations in snoRNA expression levels have been observed in age-related conditions, such as cancer and neurodegenerative diseases, suggesting their potential influence on cellular regulation, stress response, and overall genome stability. However, direct studies correlating RNA5SP155 with aging specifically appear limited.

### 3. Drug Interactions:
There are currently no specific drugs or drug classes definitively documented to directly interact with RNA5SP155 in the available literature. SnoRNAs are not typically direct targets for drugs; however, pathways and mechanisms where they are involved can be indirectly affected by agents acting on related metabolic or RNA processing pathways. Further research may identify interactions as more is learned about the roles of snoRNAs in gene regulation and disease mechanisms.

### 4. Pathways and Biological Processes:
RNA5SP155, as a small nucleolar RNA, is involved primarily in the following biological processes:
- **rRNA Methylation:** RNA5SP155 likely assists in the methylation of ribosomal RNA, a crucial step for the proper assembly and function of ribosomes.
- **Ribosome Biogenesis:** As part of the machinery responsible for processing pre-rRNA into mature rRNA, it plays a role in producing the components necessary for ribosomal assembly.
- **Gene Regulation:** SnoRNAs like RNA5SP155 may influence the stability and processing of other RNAs, linking them indirectly to various regulatory pathways.

### Summary
RNA5SP155 is a small nucleolar RNA gene involved in ribosome biogenesis and rRNA modification processes. While it has not been directly connected to aging or specific drugs, its functions suggest a significant role in cellular processes that could impact age-related degeneration and disease. Further research into the interactions and regulatory roles of snoRNAs could provide deeper insights into their implications in gene expression and disease mechanisms.
