Visceral Adipose Tissue Remodeling In Pancreatic Ductal Adenocarcinoma Cachexia: The Role Of Activin A Signaling, Pauline Xu
Theses & Dissertations
Pancreatic ductal adenocarcinoma (PDAC) is currently the third leading cause of cancer death in the United States and is projected to become the second leading cause by the year 2030. Prognosis for patients with metastatic disease remains dismal, with cachexia as a main contributor to the low survival rate. Emerging reports indicate that PDAC patients display distinct phenotypes of cachexia development, with either adipose tissue loss preceding skeletal muscle wasting or loss of only adipose tissue. While muscle wasting has been the most frequently studied mechanism in cachexia research, changes in adipose tissue are increasingly understood as important components of …

Hepatocellular carcinomas exhibit metabolic alterations to support their proliferative and biosynthetic needs. We identified that elevated expression of the mitochondrial oxidative carboxylase, malic enzyme 2 (ME2), correlates with poorer hepatocellular carcinoma patient survival. Hepatocellular carcinoma patient tumors with high ME2 expression exhibit transcriptomic alterations indicative of PI3K/AKT/mTOR and c-Myc signaling as well as elevated central carbon, fatty acid, and redox metabolism pathways. Depletion of ME2 in the hepatocellular carcinoma cell line PLC or in the livers of mice treated with diethylnitrosamine to chemically induce hepatocellular carcinomas, results in impaired proliferation and reduced tumor formation. Additionally, the loss of …
