Project description:To identify if the alteration of Myosin activity identified in DPRs expressing cells induced alterations in the transcriptome profile of cells. For that purpose, we compared the changes in HEK293 cells transcriptome induced by a known myosin activity disruptor, Blebbistatin, with DPRs expressing cells .
Project description:The aim of this experiment was to assess the on- and off-target effects of MAPT-AS1 expression, and whether mutations/deletions to MAPT-AS1 alter these effects. SHSY5Y cells stably expressing variants of MAPT-AS1 were analyzed by Riboseq and Quantseq.
Project description:RNA-seq of differentiated organoids (day 7) from a patient with an AGR2 mutation, patients with ulcerative colitis, or non-IBD controls. After 6 days differentiation, organoids were treated for 24 hours with Tunicamycin (T7765, Sigma Aldrich,1 µg/ml) or vehicle control (0.1 % DMSO).
Project description:Effect of LPA-Mixture (16:0, 18:0 18:1 18:2, 20:4) and LPAR2 specific (H2L5186303) or LPAR1 specific (Ro6842262) Inh. in OC91s cells.
Project description:Patient-derived intestinal organoids provide an excellent tool to unravel mechanisms underlying ulcerative colitis (UC). Fresh biopsies, to isolate crypts and culture organoids, were obtained from both inflamed and non-inflamed regions from eight patients with active UC (Mayo endoscopic subscore ≥2), and from eight non-IBD controls.To address the inflammatory character of ex vivo organoids, we compared the transcriptome of biopsies, crypts and organoids derived from inflamed, and non-inflamed regions and aimed to (re-)induce inflammation ex vivo.
Project description:The mRNA m6A reader YTHDF2 is overexpressed in a broad spectrum of human acute myeloid leukemias (AML). To study the role of YTHDF2 on mRNA decay rates in leukemia, c-Kit+ cells from foetal livers of Ythdf2fl/fl; Vav-iCre (Ythdf2CKO) and Ythdf2fl/fl (Ythdf2CTL) 14.5 dpc embryos were transduced with Meis1 and Hoxa9 oncogenes and serially re-plated to generate pre-leukemic cells. Medium with 4SU was used for pre-leukemic cells labelling for 12 hours and was later replaced with 4SU-free medium (time 0). Cells were collected immediately after medium change and at 1, 3 and 9 hours for library generation. RNA from Ythdf2CKO (n=3 biological replicates) and Ythdf2CTL (n=3 biological replicates) pre-leukemic cells were used for SLAM-seq library generation.
Project description:In this project, we aimed to examine the transcriptional changes that occur after irradiation of intestinal organoid-derived subcutaneous heterotopic tumors over a 7 day period post-radiation treatment. AKPT (villinCreER;Apcfl/fl;KrasG12D/+;Trp53fl/fl;TgfbrIfl/fl) intestinal organoids were cultured, then suspended in a 50:50 phosphate buffered-saline and Matrigel mixture and subcutaneously implanted into male C57BL/6 mice. Two weeks after implantation, mice were given either a single dose of 15 Gy radiation or 3 doses of 7 Gy radiation. Tumours were harvested 4 hours, 24 hours, 3 days, and 7 days after receiving the single dose of 15 Gy or the final dose of 7 Gy radiation, as well as from corresponding non-irradiated controls. RNA was extracted from the collected tumours and processed for RNA sequencing.
