The SLC2A14 gene, part of the solute carrier (SLC) family, encodes a glucose transporter involved in the transport of glucose and dehydroascorbate across the cell membrane. Below, I will provide the additional information you requested about the SLC2A14 gene.

### 1. Associated Genes
SLC2A14 has been studied in relation to various other genes and pathways. Some associated genes and processes include:

- **SLC2A1 (GLUT1)**: Another glucose transporter implicated in glucose transport across the blood-brain barrier.
- **SLC2A4 (GLUT4)**: Insulin-regulated glucose transporter found in adipose tissues and muscle.
- **SLC2A3 (GLUT3)**: An important glucose transporter in neurons.
- **SLC2A5 (GLUT5)**: A fructose transporter.
  
SLC2A14 might also be linked to various regulatory genes involved in cellular metabolism, glucose homeostasis, and insulin sensitivity, such as **INS (Insulin)**, **IGF1 (Insulin-like Growth Factor 1)**, and others involved in signaling pathways related to glucose metabolism.

### 2. Aging or Age-Related Diseases
The role of the SLC2A14 gene in aging and age-related diseases is an area of ongoing research, but there are some interesting points:

- **Metabolic Dysregulation**: Altered glucose transport is closely associated with age-related diseases like type 2 diabetes and metabolic syndrome. Since SLC2A14 mediates glucose transport, variations or dysregulation in this gene could contribute to these conditions.
- **Oxidative Stress**: Dehydroascorbate transport, which this gene also facilitates, plays a role in cellular antioxidant mechanisms. Impaired antioxidant systems are linked with aging and age-related diseases. Therefore, SLC2A14 could be indirectly associated with senescence and related pathologies.
- **Neurodegenerative Diseases**: Given the involvement of glucose transporters in neuronal health, SLC2A14 may contribute to neurodegenerative conditions, although direct associations remain to be fully characterized.

### 3. Drug Interactions
While specific drugs or drug classes that directly interact with SLC2A14 may not be comprehensively cataloged, it is known that glucose transporters are influenced by substances that affect insulin signaling and glucose metabolism, such as:

- **SGLT Inhibitors**: These drugs are aimed at glucose reabsorption in the kidneys, potentially influencing glucose transporter functions in other tissues.
- **Metformin**: Commonly prescribed for type 2 diabetes, it indirectly affects glucose transport mechanisms and may have an impact on SLC2A family transporters.
  
Research continues to identify any specific pharmacological agents targeting SLC2A14 directly. 

### 4. Pathways and Biological Processes
SLC2A14 is involved in various pathways and biological processes, including:

- **Glucose Transport**: As a member of the GLUT transporter family, it plays a crucial role in glucose uptake by cells.
- **Dehydroascorbate Transport**: Involved in the transport of this oxidized form of vitamin C, contributing to antioxidant capacity.
- **Dietary Sugars Metabolism**: SLC2A14 is implicated in the cellular uptake of sugars, influencing metabolic pathways associated with energy production.
- **Insulin Signaling**: Though less prominent than other GLUT proteins like GLUT4, SLC2A14 may interact with insulin signaling pathways due to its role in glucose transport.

Overall, SLC2A14 is an important gene in energy metabolism and may play significant roles in age-related metabolic dysregulation. Further studies are necessary to elucidate its functions fully.
