When multiplicity of infection (MOI) was 10, HCT116 cells were co-cultured with Ad-A1+A2+C1+C2 or Ad-HK. The cells were collected after being transfected for 48 h. Untreated
cell selleck kinase inhibitor was used as control. Reverse transcription-fluoresencent quantitative polymerase chain reaction (FQ-PCR) Total RNA was extracted from each XMU-MP-1 purchase sample using Trizol (Invitrogen, Gaithersburg, MD) and reversely transcripted into cDNA using the PrimeScript RT-PCR kit (TaKaRa Bio Inc., Shiga, Japan) according to the manufacturer’s instructions. The primers for the human RhoA gene were: sense 5′-CGGGAGCTAGCCAAGATGAAG-3′, antisense 5′-CCTTGCAGAGCAGCTCTCGTA-3′, fluorescent probe 5′-FAM-AGAGATATGGCAAACAGGATTGGCG-TAMRA-3′, and the amplicon size is 158 base pairs (bps). The primers for the human RhoC gene were: sense 5′-CCTCATGTGCTTCTCCATCGA-3′, antisense 5′-CTCGTCTTGCCTCAGGTCCTT-3′, fluorescent probe 5′-FAM-TCTGCCCCAACGTGCCCATCAT-TAMRA-3′, and the amplicon size is 136 bps. The GAPDH was used as the internal control with the specific primers: sense 5′-CTTAGCACCCCTGGCCAAG-3′, antisense
5′-GATGTTCTGGAGAGCCCCG-3′, fluorescent probe 5′-FAM-CATGCCATCACTGCCACCCAGAAGA-TAMRA-3′, and the amplicon size is 150 bps. Primers and fluorescent probes were synthesized by Shanghai Sangon Biological Engineering Technology & Services Co., Ltd. (Shanghai, China). The levels of RhoA, RhoC and control GAPDH mRNA transcripts https://www.selleckchem.com/products/wnt-c59-c59.html were determined by the QRT-PCR in ABI7500 real time thermal cycler (Applied Biosystems, Foster City, CA). The PCR reactions in duplicate were subjected to an initial denaturation at 95°C for 10 seconds, followed by 40 cycles of denaturation at 95°C GBA3 for 5 seconds, annealing and extension at 60°C for 45 seconds. The value of threshold
cycle (CT) for each reaction was recorded. Western blot analysis Cell samples were lysed in ice-cold lysis buffer (Beyotime, China) with 1% PMSF (Phenylmethylsulfonyl fluoride) for half an hour, then centrifuged at 10,000 g for 20 min at 4°C and the protein concentration of the resulting supernatant was determined by the bicinchoninic acid (BCA) protein assay kit (Beyotime, China). Proteins (50 μg) were separated by 12% SDS-PAGE electrophoresis and subsequently transferred to PVDF membranes. Membranes were blocked with 5% nonfat dry milk in TBS/Tween 20 (0.05%, v/v) for 2 h at room temperature and incubated overnight at 4°C with primary antibodies directing against RhoA (Santa Cruz), RhoC (Santa Cruz) and GAPDH. The blots were washed and incubated with the horseradish peroxidase-conjugated secondary antibody (DakoCytomation), and developed with a chemiluminescent substrate, ECL Plus. An autoradiograph was obtained, and protein levels were measured using a Fluors scanner and Quantity One software for analysis (Bio-Rad). Assays were done in triplicate for each experiment, and each experiment was repeated three times.
