Total RNA from cells and tissues was extracted with TRIzol reagent (Thermo Fisher Scientific, Waltham, MA, USA). Then, 1 μg RNA was reverse transcribed into cDNA using the HiScript III 1st Strand cDNA Synthesis Kit (Vazyme Biotech, Nanjing, China). Real-time quantitative PCR was conducted using Taq Pro Universal SYBR qPCR Master Mix (Vazyme Biotech, Nanjing, China) on a CFX96 Real-Time quantitative PCR Detection System (Bio-Rad Laboratories, Hercules, CA, USA). The primer sequences were as follows: LINC01615: 5′-GAAGACAGGGGATCCCGAAG-3′ and 5′-AATGAAAGTCCAGCAGGAGGG-3′; MIR100HG: 5′-CCCAGTGCAAGGACAAAGA-3′ and 5′-GCAGAGGAGGTGTCTTCAGG-3′; LINC00702: 5′-GCAGTGGCATGATCTCGGCT-3′ and 5′-GGCCGAGGCAGGTGGATAAC-3′; LINC02544: 5′-TCTCATTCGTGGCTGGATCA-3′ and 5′-ACGCTCTCGAAATCGTGTCC-3′; SERTAD4-AS1: 5′-CCTATTCCCTGCTTCTGCGA-3′ and 5′-AGCCAGAGGTCTGGTTTTTCA-3′; FENDRR: 5′-CCACATGGATGGTTGCCACTCTC-3′ and 5′-GCTGGTACTCGGCCTTCTAATTGG-3′; GAPDH: 5′-TGAACGGGAAGCTCACTGG -3′ and 5′-TCCACCACCCTGTTGCTGTA-3′.

Real-time qPCR Analysis of CRC Cells

Check if the same lab product or an alternative is used in the 5 most similar protocols
Total RNA was extracted from HCT116 CRC cells using TRIzol® (Invitrogen; Thermo Fisher Scientific, Inc.) according to the manufacturer's instructions. cDNA was synthesized using the MLV transcriptase kit (Invitrogen; Thermo Fisher Scientific, Inc.). Fast SYBR Green master mix was used to determine the threshold cycle (Cq) value of each sample using a CFX96 real-time quantitative PCR detection system (Bio-Rad Laboratories, Inc.). GAPDH served as the gene used for normalization. The fold-changes were calculated using the relative quantification with 2−ΔΔCq (29 (link)). All reactions were performed in a 20 µl reaction volume in triplicate. The following PCR conditions were used: Initial denaturation at 95°C for 30 sec; followed by 40 cycles of 95°C for 5 sec and 60°C for 30–60 sec; and stage 3 was dissociation according to the manufacturer's protocol (cat. no. RR420; Takara Biotechnology Co., Ltd.).
The PCR primer sequences used were as follows: GAPDH forward, 5′-AAGGTCATCCCTGAGCTGAA-3′ and reverse, 5′-TGACAAAGTGGTCGTTGAGG-3′; G6PD forward, 5′-TGCATGAGCCAGATAGGCTG-3′ and reverse, 5′-GGTAGTGGTCGATGCGGTAG-3′; and PKM2 forward, 5′-ATGCAGCACCTGATAGCTCG-3′ and reverse, 5′-AGGCTCGCACAAGTTCTTCA-3′.

Mouse Tissue RNA Extraction and RT-qPCR Analysis

Check if the same lab product or an alternative is used in the 5 most similar protocols
Total RNA was extracted from mouse tissues and cells with TRIzol reagent (TaKaRa, Dalian, China). Then, RT-qPCR was performed in a CFX96 real-time quantitative PCR detection system (Bio-Rad, Hercules, CA, USA) according to the instructions of SYBR Premix Ex Taq II (2×) kit (TaKaRa, Dalian, China). The relative expression levels of mRNAs and miRNAs were calculated using the 2−∆∆Ct method. ACTB was selected as the internal reference for mRNA, and U6 was selected as the internal reference for miRNA. The primer sequences used in this study are shown in Table S1.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
