SDPR Inhibits TGF-β Induced Cancer Metastasis Through Fatty Acid Oxidation Regulation in Gastric Cancer.

ABSTRACT: Our previous studies have confirmed that transforming growth factor-β (TGF-β) plays an important role in tumor metastasis, and the serum deprivation protein response (SDPR) is a potential downstream target of TGF-β. However, the role and mechanism of SDPR in gastric cancer are still unclear. We performed gene microarray, bioinformation analysis, combined with in vivo and in vitro experimental verification, we identified that SDPR is significantly downregulated in gastric cancer, and participates in TGF-β-mediated tumour metastasis. Mechanically, SDPR interacts with extracellular signal-regulated kinase (ERK) and inhibits fatty acid metabolism key gene Carnitine palmitoyl transferase 1A (CPT1A) at transcriptional level by supressing ERK/PPAR pathway. Our findings suggest that
