ABSTRACT OBJECTIVE To explore the mechanism of Compound lizard powder reducing cisplatin resistance in gastric cancer
by regulating glycolytic activity based on phosphoinositide 3-kinase(PI3K)/protein kinase B(Akt) signaling pathway. METHODS
Human gastric cancer MKN45 and MKN45/DDP (cisplatin-resistant) cells were cultured in vitro and intervened with different mass
concentrations of cisplatin (0.1, 0.2, 0.4, 0.8, 1.6, 3.2 μg/mL) to detect the survival rate, half inhibitory concentration (IC50 ) and
drug resistance index. MKN45/DDP cells were inoculated subcutaneously in the right anterior axilla of nude mice to prepare a
transplanted tumor model of gastric cancer. After successful modeling, they were randomly divided into model group, cisplatin
group (0.002 g/kg), Compound lizard powder group (2.8 g/kg) and combination group (the same dose as each single drug
group), with 8 nude mice in each group. Each administration group was given relevant solution, twice a week (cisplatin, i.p.) or
twice a day (Compound lizard powder, i. g.) , for 4
