Research in the Chapkin lab focuses on dietary/microbial modulators related to the prevention of cancer and chronic inflammatory diseases. The lab has been continuously funded by the National Institutes of Health (NIH) for the past 36 years.
Most Recent ASN Achievement : Dr. Chapkin named American Society for Nutrition 2024 Fellow
Most Recent NIH Award: Nutritional and clinical predictors of intestinal maturation and feeding tolerance in the preterm infant
Dr. Robert S. Chapkin Recent Happenings
Dr. Robert Chapkin appointed as Distinguished Professor in 2014 has been elected to serve on the Executive Committee of the Distinguished Professors (ECDP) for a 3 year term. The University Distinguished Professor designation is bestowed upon Texas A&M University faculty members who are preeminent in their fields and have made transformational contributions – or provided an intellectually substantial “leap forward” – in their discipline. This is the highest achievement a faculty member can earn at TAMU, and demonstrates his high quality of scholarship. Dr. Chapkin is a preeminent authority in Nutrition and Chronic Disease Prevention.
Chapkin Lab Post-Doctorial Staff Happenings
We are excited to share our recent publication aimed to characterize circulating immune cell subpopulation gene expression in human milk-fed compared to cow’s milk formula-fed infants using single-cell transcriptomics. We demonstrate for the first time that human milk downregulates peripheral immune cell cytokine transcriptional signatures linked to allergic inflammation and infection relative to formula feeding.

Background: Several studies have indicated the benefits of human milk feeding to infants however, mechanisms behind positive health outcomes have not been investigated.
Objectives: The study aimed to characterize circulating immune cell subpopulation gene expression in human milk-fed (HMF) compared with cow milk formula-fed (FF) infants using single-cell transcriptomics.
8th Annual Postdoctoral Research Symposium Distinguished Postdoctoral Poster Presentation: First Place Award presented to Dr. Vanessa Montoya-Uribe

Assessing ‘field cancerization’ in a colonic stem cell mismatch repair in vivo model of Lynch syndrome
Dr. Montoya-Uribe’s research focuses on elucidating the mechanisms underlying the pathogenesis of Lynch syndrome in response to pro-inflammatory diets. Lynch Syndrome is one of the most common causes of hereditary colorectal cancer (CRC) that affects approximately 30 million people around the world. Lynch Syndrome patients have germline mutations in genes that regulate cellular DNA mismatch repair (MMR) in the body. However, the mechanisms underlying the pathogenesis of CRC in Lynch Syndrome have not been elucidated. Thus, Dr. Montoya-Uribe tracked the fate of DNA mismatch repair deficient-colonic stem cells lineages in mice fed a high-fat diet during the initial stages of CRC. Her novel findings demonstrate for the first time that MMR-deficient colonic stem cells have a selective advantage (compared to normal wildtype) and clonally expand over time. We propose that MMR-deficient crypts drive cancer initiation.

Chapkin Lab Undergraduate Student Awards
Chapkin Lab is proud to recognize Bailee McEwan’s Award for Student Research Week: 2nd Overall for Oral Presentation. She presented “Effects of p53 loss of function on plasma membrane structure, organization, dynamics, and Wnt signaling”. Bailee comes to our lab with an interest in oncology and pursuing a career in medicine.
Chapkin Lab is proud to recognize Jennie P. Kim (undergraduate trainee in nutrition). Jennie was awarded the College of Agriculture and Life Sciences Senior Merit Award for her work assessing the chemoprotective effects of short chain fatty acids on mouse colonic growth and histone deacetylase activity.
