Pancreatic ductal adenocarcinoma (PDAC) is a devastating disease with dismal prognosis. The only curative option for patients is surgery, but over 80% of patients are not surgical candidates. Unfortunately, PDAC is resistant to the three remaining options. PDAC is characterized by a profoundly hypoxic and immunosuppressive stroma, which contributes to its therapeutic recalcitrance. Alpha-smooth muscle actin+ (αSMA+) cancer-associated fibroblasts (CAFs) are the most abundant stromal component, as well as mediators of stromal deposition. The hypoxia-inducible factors (HIF1 and HIF2) coordinate responses to hypoxia, yet, despite their known association to poor patient outcomes, their functions within the PDAC tumor microenvironment (TME) …

Regulation Of Pancreatic Cancer Progression By Micronutrients, Chunbo He
Theses & Dissertations
Cancer cells rely on altered metabolism to support their uncontrolled proliferation under harsh conditions. Understanding the mechanisms of how metabolic alterations support tumor growth may provide a way to enhance current therapies. Vitamins are micronutrients that our body needs in small quantities but are essential for health maintenance. A number of metabolic processes relevant to cancer initiation and progression are also regulated by vitamins. Here, our studies showed that pancreatic ductal adenocarcinoma (PDAC) cells display an aberrant metabolism of vitamin B6 (VB6) to support their fast proliferation. VB6 was highly demanded and rapidly metabolized by PDAC cells. Depletion of VB6 …
