Many cases of acute myeloid leukemia (AML) are associated with mutational activation of RTKs such as FLT3. However, RTK inhibitors have limited clinical efficacy as single agents, indicating that AML is driven by concomitant activation of different signaling molecules. We used a functional genomic approach to identify RET, encoding an RTK not previously implicated in AML, as essential gene in different AML subtypes, and observed that RET-dependent AML cells show activation of RET signaling via ARTN/GFRA3 and NRTN/GFRA2 ligand/co-receptor complexes.

View SamplesRNAseq analysis of cell lines with ADAR1-p150 and ADAR1-p110 knock-outs and primary human tissue samples (from GSE57353 and GSE99392 data sets) to identify sites of ADAR1 editing Overall design: 12 samples: 3 cell lines (HeLa, HeLa-p150KO, HeLa-ADAR1KO) with four conditions each (no treatment, MeV-vac2(GFP)-infected, MeV-CKO(GFP)-infected, IFNA/D-treated). One biological replicate per sample. In addition, raw data files of 9 samples from series GSE57353 and GSE99392 were re-analyzed using the same data processing pipeline.

View SamplesAtopic dermatitis, a chronic inflammatory skin disease with increasing prevalance, is closely associated with skin barrier defects. A cytokine related to disease severity and inhibition of keratinocyte differentiation is IL-31. To identify its molecular targets, IL-31-dependent gene expression was determined in 3-dimensional organotypic skin models.

View SamplesUDP-sugars were identified as extracellular signaling molecules, assigning a new function to these compounds in addition to their well defined role in intracellular substrate metabolism and storage. Previously regarded as an orphan receptor, the G protein-coupled receptor (GPCR) P2Y14 (GPR105) was found to bind extracellular UDP and UDP-sugars. Little is known about the physiological functions of this GPCR. To study its physiological role we used a gene-deficient (KO) mouse strain expressing the bacterial LacZ reporter gene to monitor the physiological expression pattern of P2Y14. We found that P2Y14 is mainly expressed in pancreas and salivary glands and in subpopulations of smooth muscle cells of the gastrointestinal tract, blood vessels, lung and uterus. Among other phenotypical differences KO mice showed a significantly impaired glucose tolerance following oral and intraperitoneal glucose application. An unchanged insulin tolerance suggested altered pancreatic islet function. Transcriptome analysis of pancreatic islets showed that P2Y14 deficiency significantly changed expression of components involved in insulin secretion. Insulin secretion tests revealed a reduced insulin release from P2Y14-deficient islets highlighting P2Y14 as a new modulator of proper insulin secretion. Overall design: 10 samples from pancreatic islets isolated from wildtype mice; 10 samples from pancreatic islets isolated from P2Y14-knockout mice
