Research Summary
Our research focuses on understanding how cellular stress-response pathways drive cancer development and therapeutic response, with the goal of identifying new strategies for cancer treatment. We study heat shock transcription factors (HSF1, HSF2, and HSF4) and molecular chaperones as key regulators of tumor metabolism, survival, and resistance to therapy. Using genetically engineered mouse models and analyses of human cancer datasets, we have shown that HSF1 promotes tumor growth by supporting mitochondrial function and metabolic adaptation, highlighting it as a potential therapeutic target. Our work also uncovers how stress-response pathways influence systemic metabolism and the tumor microenvironment, providing insight into how host factors contribute to cancer progression. In addition, we have identified the HSF2–HSP110 axis as a critical mechanism for maintaining genome stability, suggesting new opportunities to sensitize tumors to radiation and other genotoxic therapies. Ongoing studies in our laboratory aim to translate these findings into therapeutic strategies that disrupt tumor-supportive stress and metabolic programs to improve cancer treatment outcomes.
Impact on Patients in Georgia
Dr. Jin investigates how cancer cells hijack stress-response machinery—specifically heat shock transcription factors—to survive and grow, with a focus on liver cancer and pancreatic cancer, two lethal malignancies with rising incidence in Georgia tied to the state's high rates of obesity and metabolic disease.
His identification of HSF2 and HSP110 as regulators of DNA repair and radiation sensitivity opens a potential new strategy for sensitizing tumors to existing radiation therapy, while his work on tumor-host metabolic interactions addresses the critical question of how systemic, but modifiable, health conditions in the patient influence cancer progression and treatment response.

Research Interests
HSF1 & Metabolic Regulation in Liver Cancer
This project studies how systemic metabolism and inter-organ communication influence hepatocellular carcinoma (HCC), particularly in the context of obesity and metabolic disease. We focus on heat shock factor 1 (HSF1) as a key regulator linking stress responses to mitochondrial function and lipid metabolism. Our findings show that HSF1 controls metabolic programs across liver and adipose tissues, shaping systemic lipid flux and tumor growth. Ongoing work aims to identify metabolic vulnerabilities that can be targeted to improve liver cancer treatment.
Targeting the HSF2–HSP110 Axis in Pancreatic Cancer
This project investigates therapeutic vulnerabilities in pancreatic ductal adenocarcinoma (PDAC) by targeting transcriptional stress responses. We focus on the HSF2–HSP110 axis as a key regulator of RNA polymerase II function, DNA repair, and transcriptional fidelity under genotoxic stress. Our studies show that disruption of this pathway increases DNA damage, impairs splicing, and enhances sensitivity to radiation, while also promoting anti-tumor immune responses. Ongoing work aims to develop strategies to target this axis and improve the effectiveness of existing therapies.
