Flotillin-2 (Flot2) is a highly conserved and ubiquitously expressed protein that
resides on the cytoplasmic side of the cell membrane within specific cholesterol
rich microdomains. Some studies have reported that overexpression of Flot2 is
related to cancer progression. However, the role of Flot2 in hepatocellular
carcinoma (HCC) remains unclarified. In this study, we aim to explore the
correlation between Flot2 expression and HCC progression and the underlying
mechanism. In the present study, overexpression of Flot2 in HCC tissues and cell
lines was detected, and forced overexpression of Flot2 significantly promoted the
proliferation, migration, invasion and metastasis of HCC in vitro and in vivo by
modulating cell cycle and inducing EMT, which was mediated via up-regulation of
Twist as a result of Raf/MEK/ERK1/2 pathway activation. In contrast, silencing
Flot2 expression inhibited these biological processes. Furthermore, high
expression of Flot2 was significantly correlated with poor prognosis of HCC
patients after curative resection and is an independent risk factor. In
conclusion, Flot2 promoted tumor growth and metastasis of HCC through modulating
cell cycle and inducing EMT. The expression of Flot2 may play a key role in HCC
progression and may be regarded as a potential poor prognostic marker for HCC.
