The ceRNA PVT1 inhibits proliferation of ccRCC cells by sponging miR-328-3p to elevate FAM193B expression

FAM193B promoted ccRCC proliferation by activating the MAPK/ERK and PI3K/AKT pathways.

The Caki-1 cells were treated with SH-FAM193B lentivirus (D) or OE-FAM193B lentivirus (E), and cell lysates were then subjected to western blot analysis to determine the levels of phosphor-ERK (p-ERK), total ERK (t-ERK), phosphor-AKT (p-AKT), and total AKT (t-AKT) compared with those in cells treated with empty lentivirus vector. (F) The levels of phosphor-ERK (p-ERK), total ERK (t-ERK), phosphor-AKT (p-AKT), and total AKT (t-AKT) in Caki-1 cells treated with OE-FAM193B lentivirus and/or PA compared with those in empty lentivirus vector-treated cells.
