Sample GSM7744560 Query DataSets for GSM7744560
Status Public on Oct 16, 2023
Title Cereblon_Overexpression, scRNA-seq
Sample type SRA
 
Source name Ciona intestinalis type A
Organism Ciona intestinalis
Characteristics tissue: Mid tailbud embryo
genotype: Tbx6b>Crbn-T2A-GFPCAAX
Treatment protocol Fertilized eggs were electroporated with either plasmids coding for a membrane GFP expressed in the tail muscle (Tbx6b>T2A-GFPCAAX, control condition) or plasmids coding for Cereblon and a membrane GFP expressed in the same tissue (Tbx6b>Crbn-T2AGFPCAAX, Crbn overexpression condition). Once the fluorescence could be detected, morphologically heathly GFP+ embryos were selected.
Growth protocol Gametes from Ciona intestinalis type A were collected as described by Christians and Collegeagues in 2009. Fertilized eggs were electroporated (see treatment protocol) and grow until the mid tailbud stage.
Extracted molecule polyA RNA
Extraction protocol Mid tailbud embryos were dissociated into single cells using trypsin in sea water following the protocol published by Cao and colleagues in 2019.
Between 1000 and 2000 cells per condition were loaded onto the Chromium Controller (10x Genomics). The cells were lysed, the polyA RNA was retro-transcribed, barcoded with the Chromium Single Cell 3′ Library and Gel Bead Kit v3 (10x Genomics) using the protocols provided by the manufacturer. Nextera DNA library prep kit (Illumina) was used to construct Illumina sequencing libraries from amplified cDNA. The libraries were then sequenced on a Illumina NovaSeq 6000 instruments with the SP reagent kit (100 cycles, paired-end).

Instrument model Illumina NovaSeq 6000
 
Description Single cell RNA sequencing from Ciona mid tailbud embryos expressing in the tail muscle GFP targeted to the membrane and Cereblon (Crbn)
Data processing Filtering, quality control of the raw sequencing and generation of the FASTQ files were performed as described by Cao and colleagues in 2019. Briefly, the raw sequencing reads were filtered by Illumina NovaSeq Control Software. Reads aligning to phix using Bowtie version 1.1.1 and those falling the default chastity filter of Illumina were removed. To separate control and Crbn overexpression conditions, the reads were demultiplexed using barcode_splitter version 0.18.2, allowing one mismatch in the barcode.
To generate the gene barcode matrices, the FASTQ files were processed with 10x Cell Ranger version 3.0.0.
