Ninety-five original research projects from aspiring physician-scientists were on display at the 2024 Medical Student Research Forum at the Jacobs School of Medicine and Biomedical Sciences.
The medical students showcased projects they conducted at the University at Buffalo, its partner health care agencies and institutions throughout the nation.
They shared their work with faculty members and peers in detailed poster presentations.
A faculty panel selected four outstanding projects for special recognition during the event, which took place Jan. 24 in the second-floor atrium of the Jacobs School building.
Allison Brashear, MD, MBA, UB’s vice president for health sciences and dean of the Jacobs School, announced the winners and gave closing remarks. She noted that student poster submissions increased 26 percent from the previous year.
“This is really being about on the journey to becoming a researcher. It is so important in medicine,” she said. “Whether you are at the bench, the bedside or you are out in the community, that is the way we are going to make an impact. That is how we end up bringing change into our patients and into our community.”
“You do not have to be in a lab to be a researcher. You can do research in any way and any shape you can contribute,” Brashear added. “There are multiple ways to be a researcher. And there is a wonderful pathway through each and every one of you to have that as part of your future career.”
David A. Milling, MD, executive director of the Office of Medical Education and senior associate dean for medical education, also commended and encouraged the students.
“You should be proud of the amazing work that all of you have done. And you make us very, very proud,” he said. “Congratulations and keep up the good work. Just because the Research Forum is done, don’t stop working on your projects. There are a lot more things to get accomplished in the time that you have left here.”

“Characterization of the Molecular Genetic Mechanism of the CHRFAM7A Inverted Allele”
CHRFAM7A is a human-specific fusion gene comprised of a fusion between CHRNA7 (alpha 7 nicotinic acetylcholine receptor) and ULK4 (an ULK kinase). This gene is found in 99% of the human population and has robust associations with many neuropsychiatric disorders.
The gene can be found in either direct or inverted orientations (both of which are equally prevalent in the population), but only the direct orientation is translated and incorporated into the α7 nicotinic acetylcholine receptor (α7NAChR). The mechanism of the inverted allele, meanwhile, remains uncertain, though it has been shown to be strongly associated with diseases such as schizophrenia.
The researchers hypothesized that the inverted allele functions through an RNAi mechanism targeting either CHRNA7 or ULK4 (the two genes involved in the fusion gene). They used isogenic iPSC cell lines and neuronal progenitors to compare CHRNA7 expression in null (UB068) versus inverted CHRFAM7A (UB068_Δ2bp) cell lines.
They found that CHRFAM7A expression did not affect CHRNA7 gene expression. They then conducted immunoprecipitation studies with anti-CHRFAM7A and anti-α7NAChR antibodies to detect translation of CHRFAM7A and CHRNA7 in null versus inverted lines. The researchers found that CHRFAM7A was not translated in the inverted line, and that translation of CHRNA7 did not differ between the null and inverted genotypes, suggesting that the inverted allele does not regulate CHRNA7.
These results are consistent with the hypothesized RNAi regulatory mechanism of the CHRFAM7A inverted allele and suggests that the inverted allele regulates ULK4 expression. Improved understanding of this inverted RNAi mechanism will hopefully provide context for why the inverted allele holds such strong associations with neuropsychiatric disease.

“Predictive Accuracy of Rightward Extrapolation of the Left Ventricular End-Diastolic Pressure-Volume Relationship in Healthy Swine”
Objective: Myocardial stiffness is a primary determinant of left ventricular (LV) diastolic function and can be quantitatively described by the end-diastolic pressure-volume relationship (EDPVR). The EDPVR is traditionally derived by measuring LV end-diastolic pressure (EDP) and volume (EDV) during transient reductions in venous return (preload). However, the accuracy of this approach in predicting changes in LVEDP in response to a rise in LVEDV via rightward extrapolation has not been directly studied. Accordingly, the researchers sought to assess the predictive accuracy of preload reduction-derived EDPVRs in estimating LV diastolic stiffness (ΔLVEDP/ΔLVEDV) in healthy swine.
Conclusions: Rightward extrapolation of the EDPVR derived via IVC occlusion underestimates the rise in LVEDP when LVEDV is increased in the normal heart. This was observed with increased afterload (aortic occlusion) as well as when afterload and preload were simultaneously increased via PE. These findings highlight challenges in quantifying myocardial stiffness and reinforce the importance of assessing the hemodynamic response to increased LV loading directly, rather than extrapolating from EDPVRs created via transient preload reduction.

“Race, Gender, Healthcare, and Research Perceptions Among Orthopaedic Patients: A Qualitative Study”
Race and gender impact health outcomes in multiple and complex ways. Direct patient experiences as well as patient attitudes and beliefs about race and gender may affect various aspects of health care, including patient willingness to participate in health care research.
This study aimed to describe 1) patient perceptions of racial and/or gender influences on their health care and 2) attitudes and barriers related to orthopaedic research participation among primarily Black/African American orthopaedic patients.
Twenty patients between the ages of 45 to 85 who presented with knee pain to an orthopedic clinic within a Level 1 county hospital were interviewed.
Half of the interviewed patients in this study perceived race or gender to be factors in their health care. The most salient factors included the quality of care received as well as their provider choice. Patients who expressed a preference for a provider desired a shared experience (e.g., concordant gender) with their provider, which is consistent with existing literature. Among the interviewed orthopaedic patients, there was a moderate to high level of trust in their provider.

“Complement Signaling as a T-Cell Checkpoint in Ovarian Cancer Microenvironment”
Durable antitumor immunity requires expansion and activation of tumor antigen-specific T cells. However, multiple immunosuppressive pathways are obstacles to T cell-driven antitumor immunity, and novel approaches are required to abrogate suppressive pathways.
The researchers used an ex vivo model consisting of neutrophils and T cells from healthy donors or patients with ovarian cancer (OC) and ascites fluid from OC patients or malignant effusions from other cancers as authentic components of the human tumor microenvironment (TME).
The researchers observed that neutrophil suppressor phenotype is dependent on neutrophil-T cell contact and several neutrophil functions that include complement signaling and NADPH oxidase. Neutrophil suppressors have broad effects on pathways driving T cell proliferation and activation including inhibition of stimulated T cell proliferation, cytokine responses, metabolic changes and mTOR activation.
Though exposure to OC ascites fluid supernatants does not inhibit CD3/CD28-stimulated T cell proliferation, it dramatically reduces cytokine production (e.g., IL-2 and IFN-γ) important for T cell activation. Importantly, stimulated T cell cytokine production was rescued by complement inhibition in TME. While complement C3-inhibitors restored Il-2 production, restoration is not dependent on C3aR and C5aR inhibitors.
These results will guide subsequent T cell signaling studies that will delineate mechanisms by which complement signaling is a checkpoint on T cell cytokines responses in the TME.
