Regulatory elements cREs are essential for the spatio temporal control of gene expression during development and disease. However cRE activity is highly dependent on cell and tissue type. The developing heart is composed of several cell types predominantly cardiomyocytes. Therefore cardiomyocytes specific modelling is required to understand the cis regulation of the developing heart. Zebrafish are an ideal model to study heart development as they share a number of physiological features with the human heart during development. Therefore we present a comprehensive cardiomyocyte specific repertoire of cREs isolated from zebrafish larvae. This data combines live transcriptomics and epigenetic profiling providing insights into cREs and their associated genes involved in heart development. We further perform a transgenic reporter assay for the identified cREs of bmp10 and popdc2 genes validating these genomic regions as cardiac regulatory elements. We share this comprehensive reproducible cardiomyocyte specific cRE resource as an interrogable web tool for understanding the epigenetic and transcriptomic mechanisms underlying heart development and emergence of congenital heart defects.

Here we used a chemo genetic model of beta cell excitotoxcity coupled with single cell RNA sequencing to understand beta cells response to chronic stress.

Vulnerable beta cells that progressed towards death showed upregulation of genes implicated in apoptosis inflammation and immune system activation.

This is followed by Illumina sequencing on a Novaseq6000 50 bp PE S1 flowcell aiming at an average sequencing depth of 0.6 mio reads per cell. dT primer: C6 aminolinkerAAGCAGTGGTATCAACGCAGAGTCGAC TTTTTTTTTTTTTTTTTTTTTTTTTTTTTTVN where N represents a random base and V any base beside thymidine; TSO primer: AAGCAGTGGTATCAACGCAGAGTACATrGrGrG where rG stands for ribo guanosine; UP primer: C6 aminolinker AAGCAGTGGTATCAACGCAGAGT,,RNA-Seq,TRANSCRIPTOMIC,cDNA,PAIRED,ILLUMINA,Illumina NovaSeq 6000,,SRP495499,,loader:fastq load.py,L53556_Track-95157_R1.fastq.gz L53556_Track-95157_R2.fastq.gz,fastq fastq,90084054.0,883177.0,GSM8149985 r1,0:51 1:51,A:24491087;C:18640738;G:19792986;T:27154578;N:4665,51,51,,,24491087,18640738,19792986,27154578,4665,SRX23964321,SRS20763963,SRA1825239,"Dresden-concept Genome Center, TU Dresden","Ninov Lab, CRTD, TU Dresden",2,0.78647,0.79489,0.08515,0.09456,0.98849,0.98857,0.63931,0.66604,51,51,B,B,biological fallback assumption,illumina,novaseq_era,unknown,random_priming,unknown,sc,single_cell_plate,smartseq,,Germany,2024-03-15,Undetermined,Larval,Pancreas,Endocrine System
