To explore the effects of ginsenoside Rh2 on the development of colon cancer through microRNA-128-3p(miR-128-3p)/growth differentiation factor 15(GDF15) mediated wingless-type MMTV integration site family member (Wnt)/β-catenin signaling pathway.
SW620 colorectal cancer cells were randomly divided into the following groups: Control group (standard culture), experimental group (treated with ginsenoside Rh2 at 20 μmol·L-1), NC inhibitor group (transfected with NC inhibitor), miR-128-3p inhibitor group (transfected with miR-128-3p inhibitor), ginsenoside Rh2 + miR-128-3p inhibitor group (treated with ginsenoside Rh2 at 20 μmol·L-1 and transfected with miR-128-3p inhibitor), and ginsenoside Rh2+miR-128-3p inhibitor+si-GDF15 group (treated with ginsenoside Rh2 at 20 μmol·L-1, transfected with miR-128-3p inhibitor and si-GDF15). Quantitative real-time polymerase chain reaction (qRT-PCR) was used to detect the relative expression levels of miR-128-3p and GDF15 mRNA. Cell proliferation was assessed using 5-ethynyl-2′-deoxyuridine (EdU) incorporation assay. Western blotting was employed to detect the protein relative levels of myelocytomatosis oncogene (Myc) and β-catenin.
The relative expression levels of miR-128-3p in the control group and experimental group were 1.00±0.16 and 1.56±0.25, respectively; the relative expression relative levels of GDF15 mRNA were 1.00±0.12 and 0.43±0.05, respectively; the proliferation rates were (88.76±8.56)% and (35.89±4.05)%, respectively; the v-myc avian myelocytomatosis viral oncogene homolog (Myc) protein levels were 1.00±0.21 and 0.45±0.06, respectively; and the β-catenin protein relative levels were 1.00±0.23 and 0.52±0.07, respectively. Compared with the control group, the above indicators in the experimental group showed statistically significant differences (all P<0.05). In the ginsenoside Rh2+miR-128-3p inhibitor group and ginsenoside Rh2+miR-128-3p inhibitor+si-GDF15 group, the cell proliferation rates were (68.56±7.12)% and (50.56±5.18)%, respectively; the Myc protein relative levels were 0.86±0.12 and 0.61±0.08, respectively; and the β-catenin protein relative levels were 0.71±0.09 and 0.58±0.08, respectively. The above indicators in the ginsenoside Rh2+miR-128-3p inhibitor group compared with the experimental group, and those in the ginsenoside Rh2+miR-128-3p inhibitor+si-GDF15 group compared with the ginsenoside Rh2+miR-128-3p inhibitor group, all showed statistically significant differences (all P<0.05).
Ginsenoside Rh2 can inhibit the proliferation and migration of colon cancer SW620 cells, and promote the apoptosis, which may be related to the regulation of ginsenoside Rh2 on the miR-128-3p/GDF15 to inhibit Wnt/β-catenin signaling pathway.
