Megjegyzések:	Brown and beige adipocytes can be activated by β-adrenergic agonist via cAMP-dependent signaling. Performing RNA-sequencing analysis in human cervical area-derived adipocytes, we found that dibutyryl-cAMP, which can mimic in vivo stimulation of browning and thermogenesis, enhanced the expression of browning and batokine genes and upregulated several signaling pathway genes linked to thermogenesis. We observed that the expression of Inhibitor of DNA binding and cell differentiation (ID) 1 and particularly ID3 was strongly induced by the adrenergic stimulation. The degradation of ID1 and ID3 elicited by the ID antagonist AGX51 during thermogenic activation prevented the induction of proton leak respiration that reflects thermogenesis and abrogated cAMP analogue-stimulated upregulation of thermogenic genes and mitochondrial complex I, II, and IV subunits, independently of the proximal cAMP-PKA signaling pathway. The presented data suggests that ID proteins contribute to efficient thermogenic response of adipocytes during adrenergic stimulation.

Cím:	miR-146a modulates TLR1/2 and 4 induced inflammation and links it with proliferation and lipid production via the indirect regulation of GNG7 in human SZ95 sebocytes / Dull Katalin, Fazekas Fruzsina, Deák Dávid, Kovács Dóra, Póliska Szilárd, Szegedi Andrea, Zouboulis Christos C., Törőcsik Dániel

Megjegyzések:	Activation of Toll-like receptors (TLR) 1/2 and 4 are central in inducing inflammation in sebocytes by regulating the expression of protein coding mRNAs, however the microRNA (miRNA) profile in response to TLR activation and thus the possible role of miRNAs in modulating sebocyte functions has not been elucidated. In this work we identified miR-146a to have the highest induction in the TLR1/2 and 4 activated SZ95 sebocytes and found that its increased levels led to the down-regulation of IL-8 secretion, decreased the chemoattractant potential and stimulated the proliferation of sebocytes. Assessing the gene expression profile of SZ95 sebocytes treated with a miR-146a inhibitor, the induction of GNG7 was one of the highest, while when cells were treated with a miR-146a mimic, the expression of GNG7 was down-regulated. These findings correlated with our in situ hybridization results, that compared with control, miR-146a showed an increased, while GNG7 a decreased expression in sebaceous glands of acne samples. Further studies revealed, that when inhibiting the levels of GNG7 in SZ95 sebocytes, cells increased their lipid content and decreased their proliferation. Our findings suggest, that miR-146a could be a potential player in acne pathogenesis by regulating inflammation, inducing proliferation and, through the indirect down-regulation of GNG7, promoting the lipid production of sebocytes.

Cím:	Extensive epigenetic and transcriptomic variability between genetically identical human B-lymphoblastoid cells with implications in pharmacogenomics research / Lilla Ozgyin, Attila Horvath, Zsuzsanna Hevessy, Balint L. Balint
Dátum:	2019
ISSN:	2045-2322
Megjegyzések:	Genotyped human B-lymphoblastoid cell lines (LCLs) are widely used models in mapping quantitative trait loci for chromatin features, gene expression, and drug response. The extent of genotype-independent functional genomic variability of the LCL model, although largely overlooked, may inform association study design. In this study, we use flow cytometry, chromatin immunoprecipitation sequencing and mRNA sequencing to study surface marker patterns, quantify genome-wide chromatin changes (H3K27ac) and transcriptome variability, respectively, among five isogenic LCLs derived from the same individual. Most of the studied LCLs were non-monoclonal and had mature B cell phenotypes. Strikingly, nearly one-fourth of active gene regulatory regions showed significantly variable H3K27ac levels, especially enhancers, among which several were classified as clustered enhancers. Large, contiguous genomic regions showed signs of coordinated activity change. Regulatory differences were mirrored by mRNA expression changes, preferentially affecting hundreds of genes involved in specialized cellular processes including immune and drug response pathways. Differential expression of DPYD, an enzyme involved in 5-fluorouracil (5-FU) catabolism, was associated with variable LCL growth inhibition mediated by 5-FU. The extent of genotype-independent functional genomic variability might highlight the need to revisit study design strategies for LCLs in pharmacogenomics.
