Bestar qpcr mastermix

The total RNA of NSCLC and normal tissue samples, as well as treated and non-treated NSCLC cells was extracted with TRIzol reagent (Invitrogen, Carlsbad, CA, USA). After determining the quality of the extracted RNA with a NanoDrop2000c spectrophotometer (Thermo Scientific, Waltham, MA, USA), 2 μg of total RNA was used as a template for the reverse transcription of cDNA that was performed using a BestarTM qPCR RT Kit (#2220, DBI Bioscience, China). The RT-PCR was performed using BestarTM qPCR MasterMix (#2043, DBI Bioscience, China) on an ABI7500 system for purposes of quantifying the levels of miR-34c and HMGB1 in NSCLC tissues and cells. The sequences of the primers used were as follows: GAPDH, F: 5ʹ-TGT TCG TCA TGG GTG TGA AC-3ʹ, R: 5ʹ-ATG GCA TGG ACT GTG GTC AT-3ʹ; U6, F: 5ʹ- CTC GCT TCG GCA GCA CA −3ʹ, R: 5ʹ-AAC GCT TCA CGA ATT TGC GT-3ʹ; miR-34c, F: 5ʹ- ACACTCCAGCTGGGAGGCAGTGTAGTTAGCTG −3ʹ, R: 5ʹ- CTCAACTGGTGTCGTGGA −3ʹ, RT: 5ʹ-CTC AAC TGG TGT CGT GGA GTC GGC AAT TCA GTT GAG GCA ATC AG-3ʹ; HMGB1F: 5ʹ-CTC GCT TCG GCA GCA CA-3ʹ, R: 5ʹ-AAC GCT TCA CGA ATT TGC GT-3ʹ. The level of HMGB1 expression was normalized to that of GAPDH, and miR-34c expression was normalized to that of U6. Gene expression was quantified using the 2^−ΔΔCt method.

Total RNAs from treated BC cell lines and tissues were all prepared using TRIzol reagent (Takara, Japan), and the cDNA was produced by 50 ng total RNAs using a BestarTM qPCR RT kit (DBI Bioscience, China). The amplification was performed on the ABI PRISM 7500 Sequence Detection System (Life Technologies, USA) with the BestarTM qPCR MasterMix (DBI Bioscience) according to the instructions obtained from the manufacturers. All primers used in the present study were synthesized by Sangon (Shanghai, China), and the sequence of primers were: GAPDH: F, 5′-TGT TCG TCA TGG GTG TGA AC-3′, R, 5′-ATG GCA TGG ACT GTG GTC AT-3′; U1: F, 5′-GGG AGA TAC CAT GAT CAC GAA GGT’, R, 5′-CCA CAA ATT ATG CAG TCG AGT TTC CC-3′; miR-933: F, 5′-ATT ATA TGT GCG CAG GGA GAC C-3′, R, 5′-GCG AGC ACA GAA TTA ATA CGA CTC ACT ATA GG-3′; TFAP2A-AS1: F, 5′-CTT GAC AGC TCC AGG GGT TA-3′, R, 5′-TCT AGA CTT GCA GGC ACA CA-3′; CDK6 F, 5′-GGC CTC AGC AGC CGC CTT AAG CTG A-3′, R, 5′-CAG GAA AGA GTT TCT GAC AAA TT-3′; cyclin D1 F, 5′-GCT GCG AAG TGG AAA CCA TC-3′, R, 5′-CCT CCT TCT GCA CAC ATT TGA A-3′; cyclin E1 F, 5′-GCC GCA GTA TCC CCA GCA AA-3′, R, 5′-TCG CAC CAC TGA TAC CCT GA-3′.

After being lysed with TRIzol buffer (#9109, Takara, Japan), total RNAs of GC tissues and cell lines were extracted and reverse transcribed into cDNA by using a Bestar™ qPCR RT kit (#2220, DBI Bioscience, China). qRT-PCR assay was carried out with BestarTM qPCR MasterMix (#2043, DBI Bioscience, China) on the ABI7300 system. The sequence of primers used in this study is shown in Table 1. Expression of miRNA was normalized to U6, and expression of mRNA was normalized to GAPDH.

The second part of the right lung tissue was frozen in liquid nitrogen for a few minutes and then transferred to –80 °C for real-time quantitative PCR (RT-qPCR) and western blot (WB) analysis. The expression levels of STAT5, RORγt, and FOXP3 in the right lung tissues were evaluated by qPCR analysis. Moreover, the expression levels of CNR2, STAT5, RORγt, and FOXP3 in the cells were also assessed. A total of 5 µg RNA from each group were obtained by TRIzol (#9109, TAKARA, China) and used as the template to form cDNA using Bestar^TM qPCR RT kit (#2220, DBI Bioscience, China). Subsequently, cDNA was amplified by qPCR on a Stratagene Mx3000P real-time PCR instrument (MX3000P, Stratagene, USA) using Bestar^TM qPCR Master Mix (#2043, DBI Bioscience) according to the manufacturers’ protocols. The sequence of primers for CNR2, STAT5, RORγt, and FOXP3 is provided in Table S1. GAPDH was used as endogenous control. The reactions and PCR amplification were performed under standard techniques (26 (link)).

HCC and para-carcinoma tissues were ground at a low temperature. TRIzol reagent (Invitrogen, USA) was used to extract total RNAs from the ground tissues and the treated HEP 3B cells according to the instruction. The obtained RNAs were quantitatively determined using a NanoDro2000c (Thermo Scientific). 1.0 µg RNA was used to synthesize cDNA using the reverse transcription kit (Takara, Japan). The expression level of each indicator was examined and quantified using BestarTM qPCR MasterMix (DBI Bioscience) based on the specification provided by the supplier. GAPDH was used as an internal control. The sequences of primers are listed in Table 1.
