Publication protocol

RNA from cells was extracted using Tri-Reagent (Sigma), as per manufacturer’s instructions.

The RNA isolated was then treated with DNase (Promega) before undergoing reverse transcription by heating to 25°C for 10 min, 55°C for 50 min and 70°C for 15 min. After this, cDNA samples were stored at −20°C.
