Among the set of 104 protein-coding mRNAs differentially expressed in pancreatic tumors we found an enrichment of gene categories encoding proteins involved in "focal adhesion" (p < 0.03; TRIP6, TRIM25, VCL, SDC1, ARPC2, DLC1, CDH1, ITGB5), "RNA transport and localization " (p < 0.01; THOC7, THOC2, RAN, NUP85, THOC3) and localizing to "basolateral plasma membrane" (p < 0.05; NOTCH4, ARPC1B, CDH1, TRIP6, VCL, TRIM25, SDC1, DLC1). This evidence concerns the gene ARPC2 and pancreatic neoplasm.
