RAB1A and hepatocellular carcinoma: To analyze whether miR-19a-3p needs to function with the help of RAB1A in HCC, we designed and used an overexpression vector for RAB1A (denoted as: RAB1A), and subsequently, mimic nc + vector, miR-19a-3p mimic + vector and miR-19a-3p mimic + RAB1A were constructed to transfect HA22T and Huh7 cells.
