| Abstract
Purpose Overexpression of HMGA2, known as small nonhistone
chromosomal protein, is associated with progression
of various tumors, including colorectal cancers. The aim of
this study was to investigate the effect of a specific HMGA2
siRNA on apoptosis and cell cycle of HCT-116 (colorectal
carcinoma) cells.
Methods The cells were transfected with siRNAs using a
transfection reagent. The cytotoxic effects of HMGA2
siRNA on colorectal carcinoma cells were determined using
MTTassay. Relative HMGA2 mRNA and protein levels were
measured by QRT-PCR and western blotting, respectively.
Apoptosis was measured by a TUNEL test based on labeling
of DNA strand breaks. We also evaluated caspase-3, caspase-
8, and caspase-9 expression by QRTPCR to determine which
pathway is involved in apoptosis. Cell cycle was assessed by
FACS and cell cycle analysis using PI DNA staining.
Results HMGA2 siRNA significantly reduced both mRNA
and protein expression levels 48 h after transfection and
dose-dependent manner in colorectal carcinoma cells.We also
showed that the silencing of HMGA2 led to the induction of
apoptosis through intrinsic pathway and cell cycle arrest in
G2/M phases of interphase in HCT-116 cells in vitro.
Conclusions These results propose that HMGA2 might play
an important role in the progression of colorectal carcinoma
and might be a potential therapeutic target for trigger apoptosis
and cell cycle arrest in colorectal carcinoma. |
