(Sigma–Aldrich). The quality and quantity of RNA recovered were assessed
by running on 1.5% agarose gel and Nanodrop spectrophotometer. RT-PCR used
1 μg RNA per sample and was carried out using the reverse
transcription kit (CODE) Applied Biosciences (kit code is 4368814). Specific
mRNA levels were determined using an ABI 7900 sequence detection system (Applied
Biosystems). Reactions were carried out in 12.5 μl volumes on 384 well
plates (Applied Biosystems) in a reaction buffer containing 2× Taqman
Universal PCR Master Mix (Applied Biosystems). Primers and probes for specific
genes were purchased in ‘Assay on Demand’ format from Applied
Biosystems (IGF1:Mm00439560_m1, MYOD:Mm00521984_m1,TP53:Mm00480750_m1,
H6PD:Mm00557617). These were normalised against 18S rRNA (Applied Biosystems) as
an internal control. Raw data were recovered as CT values and
analysed as per the 2−ΔΔCTmethod.
RT-PCR of alternative transcripts from the Hsd11b1 gene was
carried out as described in
al. (2011)
