Sequencing of freshly produced RNA following exposure of cells to DNA damage-inducing UV mimetic 4-hydroxyaminoquinolone (4-NQO)
We used Illumina-HiSeq4000 to sequence 4sU-labelled RNA samples isolated from unchallenged and DNA damaged HeLa Flp-In cells, which revealed the nature of transcriptional response folowing genotoxic stress and the contribution of P-TEFb kinase in DNA damage-induced gene transcription. Overall design: We mock treated or treated HeLa Flp-In cells for 1 or 2 hr with DMSO, 4-NQO, or 4-NQO + flavopiridol (FP) as indicated below. During the last 30 minutes of the treatments, we labeled the RNA or not with the nucleoside analogue 4-thiouridine (500µM 4sU) for 30 minutes.
