Targeting Snai1-Mediated Colorectal Cancer Chemoresistance And Stemness By Sphingosine Kinase 2 Inhibition, Harinarayanan Janakiraman, Zachary Gao, Yun Zhu, Jiangling Dong, Scott A Becker, Alhaji Janneh, Besim Ogretmen, E Ramsay Camp

Faculty, Staff and Students Publications

BACKGROUND: Epithelial-to-mesenchymal transition (EMT), cancer stem cells (CSCs), and colorectal cancer (CRC) therapy resistance are closely associated. Prior reports have demonstrated that sphingosine-1-phosphate (S1P) supports stem cells and maintains the CSC phenotype. We hypothesized that the EMT inducer SNAI1 drives S1P signaling to amplify CSC self-renewal capacity and chemoresistance.

METHODS: CRC cell lines with or without ectopic expression of SNAI1 were used to study the role of S1P signaling as mediators of cancer stemness and 5-fluorouracil (5FU) chemoresistance. The therapeutic ability of sphingosine kinase 2 (SPHK2) was assessed using siRNA and ABC294640, a SPHK2 inhibitor. CSCs were isolated from patient-derived …

Inorganic Pyrophosphate Plasma Levels In Patients With Ggcx-Associated Pxe-Like Phenotypes, Qiaoli Li, Catherine Troutman, Mary Peckiconis, Tamara Wurst, Sharon Terry

Department of Biochemistry and Molecular Biology Faculty Papers

ntroduction: Pseudoxanthoma elasticum (PXE) is an autosomal recessive ectopic calcification disorder clinically affecting the skin, eyes, and vascular system. Most cases of PXE are caused by inactivating pathogenic variants in the ABCC6 gene encoding a hepatic transmembrane efflux transporter, which facilitates the extracellular release of ATP, the precursor of inorganic pyrophosphate (PPi), a potent endogenous inhibitor of calcification. Pathogenic variants in GGCX, encoding γ-glutamyl carboxylase required for activation of vitamin K-dependent coagulation factors as well as matrix Gla protein (MGP) and Gla-rich protein (GRP), two inhibitors of ectopic calcification, have also been reported to cause cutaneous changes like those seen …
