R Scientific, Shanghai, China) inside 30 minutes of excision, and then stored in -80 refrigerator. The tissue sections of these patients had been obtained in the division of pathology with the first affiliated hospital of Guangxi Medical University. This study had acquired the approval of the Ethics Committee on the very first affiliated hospital of Guangxi Healthcare University just before specimen collection. Written informed consent was obtained from all of the individuals before surgery.Cell CultureThe HCCM line and also the HepG2 cell lines have been purchased from Shanghai Institutes for Biological Sciences Cell Resource Center and cultured in DMEM culture mediumdoi/10.2147/JHC.SJournal of Hepatocellular Carcinoma 2021:DovePressPowered by TCPDF (www.tcpdf)DovepressZhou et al(Gibco, CA, USA) with 10 fetal bovine serum (FBS, Gibco, CA, USA) in incubator at 37 with 5 CO2.RNA Extraction and PCRRNA extraction was α4β1 list achieved with E.Z.N.A.Total RNA Kit II (Omega, GA, USA) following the manufacturer’s protocol. PrimeScriptTM RT reagent Kit (Takara, Dalian, China) was applied for reverse transcription in accordance with the manufacturer’s protocol. The primers had been made and synthesized by Sangon Biotech. The sequences of PCR primers had been displayed in Table S1. qRT-PCR was performed with FastStart Universal SYBRGreen Master Mix (Roche, Germany) in QuantStudio 6 Flex Real-Time PCR technique (Thermo Fisher Scientific, USA).Building of Lentivirus and Stable Cell LinesOver-expression lentiviral vector of CYP2C8 gene have been created and synthesized by GeneCopoeia (Guangzhou, China). CYP2C8-Lv201 vector and Empty-Lv201 vector had been respectively transfected into 293T cells with Lipofectamine 3000 Reagent (Thermo Fisher Scientific, USA) for lentivirus package in line with the manufacturer’s protocol. The CYP2C8-Flag-eGFP lentiviral plus the Empty-Flag-eGFP lentiviral had been utilised to transfect HepG2 and HCCM cells at an MOI of 300. Puromycin (Solarbio, Beijing, China) was employed for screening stably transduced cells at the concentration selection of 1 g/mL. Transfection efficiency was evaluated by qRT-PCR assay and Western Blot assay.Kit (Thermo Fisher Scientific, USA). The proteins were separated with SDS-PAGE gels and after that electrically transferred on PVDF membrane. Then the PVDF membrane was blocked with BlockerTM BSA (Thermo Fisher Scientific, USA). The PVDF membrane was incubated within the main antibody at four overnight. Following washing twice in PBST, the PVDF membrane was then incubated within the secondary antibody at area temperature for 90 min. The concentrations of principal antibodies had been as follows: GAPDH 1:10000 (Proteintech, USA); CYP2C8 1:1000 (Abcam, USA); PI3K 1:1000 (Proteintech, USA); p-PI3K 1:2000 (Affbiotech, China); AKT, 1:3000 (Proteintech, USA); p-AKT, 1:3000 (Proteintech, USA); p27, 1:2000 (Proteintech, USA); CDK2 1:2000 (Proteintech, USA). Right after washing twice in PBST, the protein bands have been visualized with Bio-Rad ChemiDoc MP Imaging Technique and TXA2/TP Formulation quantified with Image Lab.Cell Counting Kit-8 (CCK8) AssaysOne hundred microliters of culture medium containing 2000 cells were planted in each and every well of 96-well plates, and four identical plates were furthermore prepared for testing at unique times. The plates containing cells were respectively added with 10 CCK8 remedy (Dojindo, Japan) every properly at 0h, 24h, 48h, 72h and 96h. Following two hours of incubation, the absorbance at 450 nm was detected with Varioskan LUX (Thermo Fisher Scientific, USA). In cytotoxicity assay for sora.
