miR‑29b suppresses proliferation and induces apoptosis of hepatocellular carcinoma ascites H22 cells via regulating TGF‑β1 and p53 signaling pathway.

MicroRNA (miR)‑29b is a key tumor regulator. It can inhibit tumor cell proliferation, induce apoptosis, suppress tumor invasion and migration, thus delaying tumor progression. Our previous studies revealed an increased level of miR‑29b in hepatoma 22 (H22) cells in ascites tumor‑bearing mice.
