Study: RNA transcription profile of different yeast mutants under glucose starvation (0.05% glucose)

Histone tail modificationscan greatly influencechromatin-associated processes. Asymmetrically modified nucleosomes exist inmultiple cell types; however,whether modifications on both sister histones contribute equally to chromatin dynamicsremainselusive. Here, we devised a bivalent nucleosome system thatallowedfor the constitutive assembly of asymmetrically modified sister histone H3s in nucleosomes inSaccharomyces cerevisiae. The sister H3K36 methylationsaffectedcryptic transcription in gene coding regions, whereassister H3K79 methylation had cooperative effectsongene silencing near telomeres.H3K4 methylation on sister histonesplayed an independent role in suppressing the recruitmentof the Gal4 activator and inhibitingGAL1transcription. Under starvation stress, the expression of glycometabolism pathway geneswasfinetuned by sisterH3K4 methylation.Thus,different modifications on sister histones act either cooperatively or independentlyto regulate transcription in response to external stimuli.

Construction protocol: Total RNA from yeast cells was isolated by RNeasy midi kit (Qiagen).The mRNA was purified from total RNA by Dynal oligo(dT) beads (Invitrogen). The first and second strand cDNA was synthesized by SuperScript III CellsDirect™ cDNA Synthesis Kit (Invitrogen) and SuperScript® Double-Stranded cDNA Synthesis Kit (Invitrogen), respectively; the resulting double strand cDNAs were followed by DNA repair and end-polishing (blunt-end) with End-It DNA End-Repair Kit (Epicentre), purified with QIAquick PCR Purification Kit(Qiagen), and dA-tailed utilizing the 3´-5´ exo-Klenow Fragment (NEB),the resulting purified fragments were ligated to adaptor oligo mix (Illumine) using Quick T4 DNA ligase (NEB). The 200-500 bp ligation products were recovered from a 2% (w/v) agarose gel using Qiagen gel extraction kit. Then followed by a PCR amplification with Solexa primers using KAPA HiFiTMHotStart kit. The 250-400 bp amplified products were purified again from a 2% agarose gel and used directly for high throughput sequencing.
