Description
Regulatory T cells (Treg) are common in the tumor microenvironment in both human pancreatic cancer and in genetically engineered mouse models of the disease. Previous studies in orthotopic syngeneic models of pancreatic cancer -recapitulated in our own data- indicated that Treg depletion results CD8+ T cell-mediated tumor regression. In human patients and in mouse models, regulatory T cells accumulate during the onset of Pancreatic Intraepithelial Neoplasia (PanIN), the earliest steps of carcinogenesis. We thus generated a genetic model to investigate the role of regulatory T cells during the onset of pancreatic carcinogenesis. Unexpectedly, depletion of Tregs during early stages of carcinogenesis led to accelerated tumor progression. Overall design: We are using KC;Foxp3DTR mice generated by crossing KC (Ptf1a-Cre;LSL-KrasG12D) with Foxp3DTR (B6.129(Cg)-Foxp3tm3(DTR/GFP)Ayr/J, Jackson Laboratory). We depleted Foxp3-expressing Tregs by Diphtheria Toxin (DT) injection to determine the requirement of Tregs during oncogenic Kras induced Pancreatic Intraepithelial Neoplasia (PanIN) formation and maintenance. To investigate the mechanisms underlying the tumor-promoting effect of Treg depletion in KC; Foxp3DTR mice we performed RNA sequencing (RNAseq) for myeloid cells (DAPI-EpCAM-CD45+CD11b+) flow-sorted from KC and KC; Foxp3DTR pancreata.

Description
Natural grape-juice fermentations involve the sequential development of different yeast species which strongly influence the chemical and sensorial traits of the final product. In the present study,we aimed to examine the transcriptomic response of Saccharomyces cerevisiae to the presence of Hanseniaspora guilliermondii wine fermentation.

Description
The NuRD complex is generally thought to repress transcription at both hyper- and hypomethylated regions in the genome. In addition, the complex is involved in the DNA damage response. Here, we show that ZMYND8 bridges NuRD to a number of putative DNA-binding zinc finger proteins. The ZMYND8 MYND domain directly interacts with PPPL? motifs in the NuRD subunit GATAD2A. Furthermore, GATAD2A and GATAD2B exclusively form homodimers and they thus define mutually exclusive NuRD subcomplexes. ZMYND8 and MBD3 share a large number of genome-wide binding sites, mostly active promoters and enhancers. Depletion of ZMYND8 does not affect NuRD occupancy genome-wide and expression of NuRD/ZMYND8 target genes in steady-state asynchronous cells. However, ZMYND8 facilitates immediate recruitment of GATAD2A/NuRD to induced sites of DNA damage. These results thus show that a specific substoichiometric interaction with a NuRD subunit paralogue provides unique functionality to a distinct NuRD subcomplex. Overall design: RNA-seq samples for HeLa FRT-TO mock, ZMYND8KO, and ZMYND8KO-rescue cells

Description
Low concentrations of the dissolved leonardite humic acid HuminFeed (HF) prolonged the lifespan and enhanced the thermal stress resistance of the model organism Caenorhabditis elegans. Furthermore growth was impaired and reproduction delayed, effects which have also been identified in other polyphenolic monomers, including tannic acid, rosmarinic acid, and caffeic acid. Moreover, a chemical modification of HF (HF-HQ), which increases its phenolic/quinonoid moieties, magnified the biological impact on C. elegans. To gain a deep insight into the molecular basis of these effects, we performed global transcriptomics on young adult (3 d) and old adult (11 d) nematodes exposed to two concentrations of HF and young adults (3 d) exposed to two concentrations of HF-HQ.
