NIH-funded research R01 grant

Investigating how vitamin A can help improve memory and learning in aging and Alzheimer's disease.

Official title: The hippocampal dentate gyrus in aging and Alzheimer's disease: boosting transcription of retinoic acid-sensitive genes through vitamin A supplementation and HDAC inhibition

Funded at Texas Tech University Health Scis Center · NIH-11076699 · Data updated 2026-11-12

This study is looking at how vitamin A and certain natural compounds might help improve memory and learning in older adults and people with Alzheimer's by boosting important brain functions that can be weakened by aging and stress.

Who could benefit from this research

Could help

Ideal candidates for this research include older adults experiencing cognitive decline or individuals diagnosed with Alzheimer's disease.

Less likely to help

Patients with cognitive impairments not related to aging or Alzheimer's disease may not benefit from this research.

What this research studies

This research focuses on the hippocampal dentate gyrus, a brain region crucial for learning and memory, which is affected by aging and Alzheimer's disease. The study aims to understand how vitamin A supplementation and the inhibition of certain enzymes can boost the expression of genes that are sensitive to retinoic acid, potentially reversing cognitive decline. By examining the effects of oxidative stress and the role of dietary antioxidants, the research seeks to uncover new therapeutic strategies for improving cognitive function in older adults and those with Alzheimer's.

Why it matters

Potential benefit: If successful, this research could lead to new treatments that enhance memory and cognitive function in aging individuals and those suffering from Alzheimer's disease.

How similar studies have gone: While there have been clinical trials involving antioxidants, this specific approach focusing on vitamin A and its effects on gene expression in the context of aging and Alzheimer's is relatively novel.
