摘要

目的

初步探讨天然小分子HEP-14对黑色素瘤SK-Mel-103细胞的抑制作用及相关机制。

方法

用不同浓度的HEP-14(2.5~40 μmol/L)处理黑色素瘤SK-Mel-103细胞后，CCK-8和平板克隆形成实验检测细胞的存活率和克隆的形成，流式细胞术检测细胞周期变化和细胞凋亡，Transwell实验检测细胞迁移能力，RT-qPCR检测CD271和STAT3基因水平的表达，Western blot检测CD271、STAT3、p-STAT3蛋白水平的表达，细胞免疫荧光检测进一步证实CD271在细胞内的表达。

结果

与对照组比较，天然小分子HEP-14能有效抑制SK-Mel-103细胞的生长和克隆的形成(

0.05)，诱导细胞G

/M期阻滞(

0.05)，促进细胞凋亡(

0.05)和抑制细胞的迁移。HEP-14显著抑制SK-Mel-103、SK-Mel-147和SK-Mel-28细胞STAT3的磷酸化(

0.05)，下调CD271的表达(

0.05)。

Abstract

Objective

To investigate the inhibitory effect of a natural small molecule

HEP-14

on melanoma SK-Mel-103 cells and its underlying mechanism.

Methods

SK-Mel-103 cells were treated with HEP-14 at different concentrations (2.5~40 μmol/L). The untreated cells were used as a control. Cell viability and colony formation were respectively assessed using CCK-8 assay and colony formation assay. Flow cytometry was applied to examine cell cycle and apoptosis. Transwell assay was used to evaluate cellular mobility. Real-time RT-qPCR was used to measure the mRNA expression of CD271 and STAT3

and Western blotting was employed to detect the protein levels of CD271

STAT3 and p-STAT3. Immunofluorescence assay was perform to confirm the expression of CD271.

Results

HEP-14 significantly inhibited the growth and colony formation of SK-Mel-103 cells (

0.05)

induced cell arrest at G2/M phase (

0.05)

promoted cell apoptosis (

0.05) and suppressed cell mobility in comparison with the untreated cells. In addition

HEP-14 treatment suppressed the phosphorylation of STAT3 (

0.05) and down-regulated the expression of CD271 (

0.05) in the melanoma cell lines SK-Mel-103

SK-Mel-147 and SK-Mel-28.

Conclusion

Natural small molecule HEP-14 effectively inhibits the proliferation and induces the apoptosis of melanoma SK-Mel-103 cells

and it suppresses the cell migration by inhibiting activation of STAT to down-regulate CD271 expression.
