Total RNA was isolated from tissues and cultured cells using Trizol reagent (Invitrogen, USA) according to the manufacturer's instructions. RNA quality and quantity were evaluated with the NanoDrop 1000 (ThermoFisher, Santa Clara, USA). The first strand cDNA was synthesized using a reverse transcriptase Kit (TaKaRa Biotechnology, Dalian, China) according to the manufacturer's guide. qRT-PCR (quantitive real-time PCR) was performed in triplicate with LightCycler2.0 (BIO-RAD) on a LightCycler 480 System (Roche Diagnostics, Thebarton, Australia). Results were normalized to glyceraldehyde 3-phosphate dehydrogenase (GAPDH) expression. The primers are below: SNHG1: Forward: 5'-GGGGTACCG TTCTCATTTTTCTACT GCTCGTG-3' and reverse: 5'-CGGGATCCATG TAATCAATCATTTTAT TATTTTCATC-3'. GAPDH: Forward: 5'-CGCTGAGTACGT CGTGGAGT-3'; reverse: 5'-CGTCAAAGGTGG AGGAGTGG -3'. The real-time PCRs were performed in triplicate and fold changes were calculated by the relative quantification (2 -ΔΔCt ) method.

Nuclear and cytoplasmic fractions were isolated using 0.5% NP-40 (Solarbio) and RNase inhibitor (Promega) and total RNA was extracted using TRIzol reagent (Sigma). Thereafter, the cDNA was synthesized using the Prime Script RT kit (Promega). The RT-qPCR was performed in triplicate using LightCycler 2.0 (BIO-RAD). The values were normalized to GAPDH for the total RNA and cytoplasmic RNA, and U6 was used as an endogenous control for nuclear RNA. PCR primers were designed on NCBI (http://www.ncbi.nlm.nih.gov/tools/prim er-blast/) and the primer sequences are listed in Supplementary 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.
