In conclusion, miR-143-3p suppresses tumour angiogenesis and growth of GBC through the ITGA6/PI3K/AKT/PLGF pathways and may be a novel molecular therapeutic target for GBC.
We also evaluated the expression of HSP90 by immunohistochemistry in human GBC tumors.In vitro assays showed that 17-AAG and GA significantly reduced the expression of HSP90 target proteins, including EGFR, AKT, phospho-AKT, Cyclin B1, phospho-ERK and Cyclin D1.
PTEN is a tumor suppressor gene that regulates the PTEN/PI3k/AKT/mTOR pathway, which is frequently altered in human cancers including gallbladder cancer (GBC).
