Wing disc transcriptomic variation from 32 Drosophila genetic reference panel (DGRP) lines selected for a broad range of wing sizes
Ontology highlight
ABSTRACT: We performed RNA sequencing of wing discs at the wandering L3 larval stage from 32 inbred lines of Drosophila genetic reference panel (DGRP) that consists of 16 big and 16 small wing lines. We aimed to understand system-wide gene regulatory mechanisms that attain the observed natural variation in wing size including the sexual size dimorphism.
Project description:Here, we validate a novel protocol, Bulk RNA Barcoding and sequencing (BRB-seq), that combines the multiplexing-driven cost-effectiveness of a single-cell RNA-seq protocol with the efficiency of a bulk RNA-seq procedure. For this we use BRB-seq protocol on human pre-adipocytes and differentiated adipocytes, and compare its effectiveness as compared to TruSeq. Indeed, one of the principal limitations of bulk RNA-seq is the time and costs of library preparation, which makes it difficult to profile many samples simultaneously. Here, BRB-seq produces 3’ libraries that exhibit similar gene expression quantification to TruSeq and maintain this quality even with low quality RNA samples.
Project description:Here, we validate a novel protocol, Bulk RNA Barcoding and sequencing (BRB-seq), that combines the multiplexing-driven cost-effectiveness of a single-cell RNA-seq protocol with the efficiency of a bulk RNA-seq procedure. For this we use BRB-seq protocol on 60 human LCL data from the 1000G project samples, in order to show its multiplexing capacity and compare its effectiveness to already published TruSeq results on same samples.
Project description:Among the diverse forms of symbioses, facultative nutritional mutualism forged by the host and its resident gut microbiota permits the symbiont to adapt to the changing nutritional environment during the host’s life time. The horizontally acquired gut bacteria in Drosophila are a perfect example of nutritional mutualists. Here, we study the Lactobacillus plantarum (Lp WJL) infection effect in the Drosophila Genetic Reference Panel (DGRP) collection in context of larvae raised in chronic undernutrtion.
Project description:RNA extracted from Drosophila wandering L3 wing imaginal discs was 2S rRNA depleted and prepared for miRNA sequencing using the QIAseq miRNA Library kit. The experiment was performed on Pacman and Dis3L2 null mutants and their respective isogenic control lines with four replicates of each condition.
Project description:RNA-seq on 120hr L3 larval wing imaginal discs. 3 replicates of dis3L2 null mutant, and 3 replicates of control wing discs. rRNA depleted, Illumina TruSeq libraries. Paired-end sequencing on a HiSeq 3000.
Project description:To characterize murine ASPCs we performed bulk RNA-seq (BRB-seq, Alpern et al., 2019) of total, CD142− and CD142+ (Aregs) mouse adipose stem and progenitor cells (ASPCs). ASPCs were collected as Lin− (CD31− CD45− TER119−) CD29+ CD34+ SCA1+ cells of the mouse subcutaneous stromal vascular fraction using FACS. The cells were sequenced directly after sort or after expansion.
Project description:This experiment investigates transcriptomic differences between two SKOV3 ovarian cancer cell strains, S1 (CW1) and S2 (SM), to assess how clonal evolution and culture conditions influence gene expression. Bulk RNA sequencing (RNA-seq) was performed on cells cultured in both 2D monolayers and 3D spheroids. The study aims to identify differentially expressed genes and pathways associated with epithelial-mesenchymal transition (EMT), proliferation, and metabolic regulation. The sequencing data were processed using standard bioinformatics pipelines, including quality control, alignment, normalization, and differential expression analysis.
Project description:To validate that the robustness of Aregs' (CD142+ ASPCs') molecular identity regardless of the antibody used, we performed transcriptomic profiling of freshly isolated CD142− and CD142+ mouse adipose stem and progenitor cells (ASPCs) sorted using four different anti-CD142 antibodies. ASPCs were collected as Lin− (CD31− CD45− TER119−) CD29+ CD34+ SCA1+ CD142+/− cells of the mouse subcutaneous stromal vascular fraction using FACS.
Project description:To explore the molecular identity of mouse adipose stem and progenitor cells (ASPCs) and more specifically of CD142+ ASPCs (Aregs), we performed bulk RNA-seq on freshly isolated total, CD142− and CD142+ ASPCs of new-born pups (P0), post-natal day 16 mice (P16), 4 week-old (4wo), 7wo and 11wo mice. ASPCs were collected as Lin− (CD31− CD45− TER119−) CD29+CD34+ SCA1+ cells of the mouse subcutaneous stromal vascular fraction using FACS.
Project description:To characterize CD142+ ASPCs (Aregs) after exposure to an adipogenic cocktail we performed bulk RNA-seq (using BRB-seq) of total, CD142− and CD142+ mouse adipose stem and progenitor cells (ASPCs), sorted using four different anti-CD142 antibodies. ASPCs were collected as Lin− (CD31− CD45− TER119−) CD29+ CD34+ SCA1+ cells of the mouse subcutaneous stromal vascular fraction using FACS.
