Project description:Purpose: We carried out small RNA sequencing to determine miRNA expression patterns of hippocampus and frontal cortex in six inbred mouse strains. We analyzed miRNA expression levels, isomiR distribution and miRNA editing events. Methods: We constructed small RNA libraries starting from the total RNA extracted from the hippocampus and frontal cortex of three animals per strain. The sequencing was carried out using Illumina HiSeq2000 (single-end). The sequence reads that passed quality filters were mapped to the mouse genome (mm10) and to known miRNAs (miRBase v21) using miRDeep2, SeqBuster, and sRNAbench, to obtain miRNA and isomiR expression levels and to predict novel miRNAs. Genome alignments were analysed for miRNA editing using FreeBayes. Results: We detected significant miRNA and isomiR expression level differences between the strains and brain regions. Most of the miRNA loci produced a number of isomiRs. Some miRNAs were consistently edited with a pattern that matches the activity of known RNA editing enzymes.

A multicenter translational biomarker phase II trial of regorafenib in patients with non-resectable pretreated colorectal cancer.

Project description:Primary objectives: The primary objective is to investigate circulating tumor DNA (ctDNA) via deep sequencing for mutation detection and by whole genome sequencing for copy number analyses before start (baseline) with regorafenib and at defined time points during administration of regorafenib for treatment efficacy in colorectal cancer patients in terms of overall survival (OS). Primary endpoints: circulating tumor DNA (ctDNA) via deep sequencing for mutation detection and by whole genome sequencing for copy number analyses before start (baseline) with regorafenib and at defined time points during administration of regorafenib for treatment efficacy in colorectal cancer patients in terms of overall survival (OS).

P. falciparum (lab strain 3d7) schizonts untreated control vs P. falciparum (lab strain 3d7) reference RNA pool

Project description:Calcium is a universal second messenger molecule which plays a significant role in several biological processes. Presence of calcium sensors (calmodulins) and calcium-dependent protein kinases in Plasmodium species suggests an important role of calcium-dependent signaling pathways in the regulation of cellular processes in the malaria parasites. Evidence for the transcriptional response of control Plasmodium falciparum asexual blood stages not treated with the calcium ionophores, A23187 and ionomycin has been presented here.

Presence of calcium sensors (calmodulins) and calcium-dependent protein kinases in Plasmodium species suggests an important role of calcium-dependent signaling pathways in the regulation of cellular processes in the malaria parasites. Evidence for the transcriptional response of Plasmodium falciparum asexual blood stages to the well-known calcium ionophore A23187 has been presented here.
