Total RNAs were extracted by trizol (Invitrogen) and cDNAs were synthetised using Rever Ace qPCR RT Kit (TOYOBO). Real-time PCR was performed using SYBR Green Realtime PCR Master Mix (Roche) and the ABI ViiA7 QPCR System (Applied Biosystems). Chromatin immunoprecipitation (ChIP) was performed to investigate whether EZH2 or/and EZH2 binding to HOXA9 promoter. ChIP assays were performed as described previously (38 (link)).

Total RNAs was extracted by TRIzol (Invitrogen) and cDNAs was synthesized using a Rever Ace qPCR RT Kit (TOYOBO). Real-time PCR was performed using SYBR Green, Real-time PCR Master Mix (Roche) and the ABI ViiA7 QPCR System (Applied Biosystems). ChIP-seq datasets were downloaded from the NCBI SRA website (https://www.ncbi.nlm.nih.gov/Traces/study/?acc=SRP385097&o=acc_s%3Aa). SRR15838293, SRR15838297, and SRR15838302 were designed to be the input groups, and the experimental group was SRR15838294, SRR15838298, and SRR15838303. All the raw reads were first quality-checked with FastQC 0.11.9 and filtered with trim_galore 0.6.9 (-q 20 –phred 33 –length 20 -e 0.1 -j 4 –stringency 5). Then, the sequences were aligned to the human genome (hg38 assembly) using Bowtie2 and sorted with samtools 1.6. After that, PCR replacements were removed using samtools 1.6. Peaks were then called with MACS2 2.1.0 [23 ] (--nomodel --extsize 300). Data visualization was performed with IGV 2.11.9 software and the ChIPseeker R package 1.32.1 [24 (link)]. ChIP assays were performed with a SimpleChIP® Kit (Agarose Beads) (CST, 22,188 S, Boston, USA) according to the manufacturer’s instructions.

Total RNAs were extracted by trizol (Invitrogen) and cDNAs were synthetised using Rever Ace qPCR RT Kit (TOYOBO). Real‐time PCR was performed using SYBR Green Realtime PCR Master Mix (Roche) and the ABI ViiA7 QPCR System (Applied Biosystems). Amplification conditions were as follows: 95°C for 15 s, 60°C for 15 s, 72°C for 45 s for 40 cycles in a 25‐μl reaction mix containing 1 × SYBR green. The expression levels of miR‐490‐3p and miR‐490‐5p were quantified using stemloop RT according to the manufacturer's protocol (Roche). All reagents for stemloop RT were obtained from Roche and RiboBio. The U6 snRNA was used as an internal control. For miRNA and mRNA PCR, the reactions were incubated in a 96‐well plate at 95°C for 10 min, followed by 40 cycles of 95°C for 20 s, 60°C for 20 s and 72°C for 1 min. The following primers were used for qPCR: PIK3CA‐5′, TGCTAAAGAGGAACACTGTCCA; PIK3CA‐3′, GGTACTGGCCAAAGATTCAAAG; TBP‐5′, TGCACAGGAGCCAAGAGTGAA; TBP‐3′, CACATCACAGCTCCCCACCA.

Total RNA was extracted from bladder cancer tissues or cell lines using TRIzol reagent (Invitrogen, USA) and then reverse transcribed using Rever Ace qPCR RT Kit (TOYOBO, Shanghai), according to the manufacturer’s instructions. Real-time PCR of TUG1 or mRNAs was performed using FastStart Universal SYBR Green Master (Roche, IN, USA) with the ViiA 7 Dx PCR System (Applied Biosystems, USA), while the expression of mature miRNA was determined by PCR with All-in-One miRNA qRT-PCR reagent kit (GeneCopoeia, USA).
Genomic DNA was isolated using QIAamp DNA Mini Kit (QIAGEN), and bisulfite modification of the genomic DNA was carried out using an Epitect Bisulfite Kit (QIAGEN), according to the manufacturer’s instructions. Methylation-specific PCR (MSP) primers for miR-194-5p gene promoter were designed with Methprimer (http://www.urogene.org/cgi-bin/methprimer/methprimer.cgi), using the same methods as Zhou et al.38 (link) Methylation or unmethylation primers for MSP were as follows: methylation, 5′-GGTTATGAGTAGAAGGGGTTGAC-3′ (forward), 5′-TCAATCTTAAACACTATCCGAACG-3′ (reverse); and unmethylation, 5′-GTTATGAGTAGAAGGGGTTGATG-3′ (forward), 5′-CAATCTTAAACACTATCCAAACACC-3′ (reverse).

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.
