The MIR4756 gene encodes a microRNA (miRNA) that plays a critical role in the post-transcriptional regulation of gene expression. Here’s a comprehensive summary that integrates the additional areas you requested:

### 1. Associated Genes
While specific associated genes for MIR4756 may not be directly stated in the summaries, miRNAs often target multiple mRNAs for regulation. Some computational predictions and experimental studies have linked miRNAs (including pre-miRNA and mature miRNA forms) to various mRNA targets. Commonly associated genes may include those involved in:

- Cellular proliferation
- Differentiation
- Developmental processes

To find specific genes associated with MIR4756, resources such as miRTarBase or TargetScan can be utilized to predict and validate miRNA-target interactions.

### 2. Aging and Age-Related Diseases
The role of miRNAs, including MIR4756, is increasingly recognized in the context of aging and age-related diseases. Some areas of investigation include:

- **Cellular Senescence**: Certain miRNAs can influence the senescence process, where cells lose the ability to divide and function. Altered expression of miRNAs is associated with aging.
- **Neurodegenerative Diseases**: MiRNAs have been implicated in the regulation of genes involved in neuroprotection and neurodegenerative conditions, such as Alzheimer’s disease.
- **Cardiovascular Diseases**: Dysregulation of miRNAs can contribute to heart diseases, which are prevalent in aging populations.
  
Research on specific effects of MIR4756 on these pathways remains active, so it is important to consult current literature for the latest findings.

### 3. Drug Interactions
Currently, direct interactions of specific drugs with the MIR4756 gene are not well-documented. However, several classes of drugs that target the pathways regulated by miRNAs—including those involved in inflammation, cancer, and metabolic disorders—might influence its expression indirectly. Some general categories of drugs that could be considered include:

- **Antisense Oligonucleotides**: Drugs designed to target specific miRNAs for modulation.
- **Cancer Therapeutics**: Certain chemotherapeutics may affect miRNA expression profiles.

More thorough exploration in drug databases like DrugBank, or specific literature reviews may provide insights on drugs that impact the expression or functionality of MIR4756.

### 4. Pathways and Biological Processes
MIR4756 is involved in multiple biological processes owing to its miRNA nature. Some key pathways and processes may include:

- **Regulation of Gene Expression**: By modulating target mRNAs, MIR4756 can impact various signaling pathways.
