Study on the reversal effect of Qingfei huayu jiedu formula on drug resistance in non-small cell lung cancer cells
To investigate the reversal effect of Qingfei huayu jiedu formula (QFHYJDF) on drug resistance in non-small cell lung cancer (NSCLC) cells based on the microRNA-641 (miR-641)/extracellular signal-regulated kinase (ERK) signaling pathway.
METHODS
2
The human parental NSCLC cell line A549 was used to establish gefitinib-resistant cells A549/GR by combining concentration gradient increment with high-concentration pulse strategy. After screening for optimal intervention concentration and duration, the resistant cells were divided into a control serum group (treated with 20% blank serum for 48 h), QFHYJDF-containing serum group (treated with 20% QFHYJDF-containing serum for 48 h), and the normally cultured group (normally cultured for 48 h). The cell relative viability, total apoptosis rate, as well as the expression levels of miR-641, neurofibromin 1 (NF1), ERK1/2, and phosphorylated ERK1/2 (p-ERK1/2), were assessed in each group.
RESULTS
2
Compared with the normally cultured group and the control serum group, the QFHYJDF-containing serum group exhibited significantly decreased cell relative viability and significantly
increased total apoptosis rate (
P
<0.05). Moreover, the expression of NF1 protein was significantly up-regulated, while the expression levels of miR-641 and p-ERK1, p-ERK2 proteins were significantly down-regulated in the QFHYJDF-containing serum group (
P
<0.05).
CONCLUSIONS
2
QFHYJDF can inhibit proliferation and promote apoptosis of gefitinib-resistant lung cancer cells, which may be associated with up-regulating NF1 protein expression, down-regulating miR-641 expression, and inhibiting the activity of the ERK signaling pathway.
