The RNA-Binding Protein DDX39B Promotes Colorectal Adenocarcinoma Progression by Stabilizing DCLK1
As an RNA-binding protein (RBP), DDX39B increased the stability of DCLK1-B mRNA, a variant highly expressed in colorectal cancer known to promote cancer stemness, thereby augmenting its protein expression. Notably, silencing of DCLK1-B effectively abrogated the pro-metastatic effects induced by DDX39B overexpression. Overall design: RNA-seq was performed after overexpression of DDX39B in colorectal adenocarcinoma cells SW480, and differentially expressed genes were screened compared with control cells.
