Total RNA was extracted from T and SEZ tissues using TRIzol (Invitrogen) according to the manufacturer’s instructions. RNA was treated with DNase (Qiagen) and cDNA was synthesized from 5μg of total RNA using Random Primers (Invitrogen) and a Superscript III First-Strand Synthesis System for real-time PCR (RT–PCR) (Invitrogen). The RT–PCR for Nestin, Gfap, Sox2 and MIB1 transcripts was performed using CFX96 RT–PCR (Biorad), RT2 qPCR Primer Assay and SYBR Green Master Mix (Qiagen) according to the manufacturer’s instructions. 18S was used as the housekeeping reference. Relative expression quantification was performed by the ΔΔCT method. Experiments were performed in triplicate and each experiment was repeated 3 times.

Gene Expression Analysis by qPCR

Check if the same lab product or an alternative is used in the 5 most similar protocols
Total RNA of tissues was isolated using TRIzol Reagent (Invitrogen, Carlsbad, CA, USA) following the manufacturer’s instructions. RNA was treated with DNase and run on the gels to validate the purity and quality. The cDNA was synthesized from 1 μg RNA using the SuperScript III First-Strand Synthesis System for real-time PCR (RT-PCR) (Invitrogen). Real-time PCR was performed on a Bio-Rad qPCR machine using the SYBR Green PCR Master Mix, according to the manufacturer’s recommended procedures. The primers were as follows: GHS-R forward primer 5′-GGACCAGAACCACAAACAGACA-3′, GHS-R reverse primer 5′-CAGCAGAGGATGAAAGCAAACA-3′; This primer set flanks the intron, which allows us to distinguish its expression from GHS-R 1b. UCP1 forward primer 5′-GTGAAGGTCAGAATGCAAGC-3′, UCP1 reverse primer 5′-AGGGCCCCCTTCATGAGGTC-3′. 18S and β-actin were used as housekeeping genes.

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.
