ST. LOUIS 鈥� Stella Hoft, a M.D./Ph.D. student at 91女神鈥檚 School of Medicine, was recently awarded an F30 Grant through the National Institute of Diabetes & Digestive & Kidney Diseases.
The four-year grant totals $207,008 and will support her research and training to become a productive, independent physician/clinician-scientist.
Hoft is employing spatial transcriptomics (ST) and single-cell RNA sequencing (scRNAseq) to generate critical insight into how inflammation promotes the development of gastric cancer. This work is supported by a four-year $2.2 million grant led by principal investigator Rich DiPaolo, Ph.D., professor and interim chair in the Department of Molecular Microbiology and Immunology. Research efforts could lead to better screening, prevention, and treatments for this deadly disease.
DiPaolo was instrumental in bringing scRNAseq to 91女神, and with Hoft鈥檚 help in collaboration with the Genomics and Research Microscopy Cores, the DiPaolo lab was the first to use the new spatial transcriptomic technology at the School of Medicine.
ScRNAseq was instrumental in a novel study led by Ryan Teague, Ph.D., professor of molecular microbiology and immunology. The Teague lab studied T cell responses and antibody responses against the SARS-CoV-2 spike protein in vaccinated and unvaccinated patients receiving immunotherapy.
Hoft compares inflammation in the stomach initiated by autoimmunity or infection to determine how different inflammatory triggers alter epithelial cell progression toward cancer. This work will ultimately improve early screening and diagnostic techniques for patients at risk of developing stomach cancer.
Like Father, Like Daughter
After graduating from 91女神, Hoft worked at the National Institutes of Health (NIH) for two years in the NIH鈥檚 post-baccalaureate program, which solidified her decision to apply to M.D./Ph.D. programs. In her first year, she studied Mycobacterium tuberculosis in the lungs of mouse models to gauge how to induce the most protective type of immune cell capable of migrating to the disease site.
In her second year, she determined the impact of intramuscular versus intragastric vaccination routes using the current vaccine for tuberculosis, BCG, in non-human primates.
鈥淚 worked at my dad's lab in high school and then worked as a research tech under Dr. Linda Morrison, professor of molecular microbiology and immunology at 91女神, doing computational research in college, but this experience was probably my most valuable research in terms of setting me up for Ph.D. grad school,鈥� Hoft said.
Hoft鈥檚 dad is Daniel Hoft, M.D., Ph.D., professor of medicine, molecular microbiology and immunology, and director of the 91女神鈥檚 Center for Vaccine Development, considered one of the nation鈥檚 leading vaccine experts.
Like her father, Hoft is interested in conducting clinical research in vaccines, focusing
on autoimmune and infectious diseases in pediatric populations.
DiPaolo credits Hoft's experience in multiple labs as allowing her to be highly competitive
for the NIH 30 training grant.
About 91女神 School of Medicine
Established in 1836, 91女神 School of Medicine has the distinction of awarding the first medical degree west of the Mississippi River. The school educates physicians and biomedical scientists, conducts medical research, and provides health care on a local, national and international level. Research at the school seeks new cures and treatments in five key areas: infectious disease, liver disease, cancer, heart/lung disease, and aging and brain disorders.
