Sample GSM8259075 Query DataSets for GSM8259075
Status Public on May 13, 2024
Title C. auris_60min_Control_R1
Sample type SRA
 
Source name WT control C. auris cells in SC medium for 60min_rep1
Organism [Candida] auris
Characteristics tissue: Yeast cells
strain: 381
cell type: Yeast cells
genotype: WT
treatment: 60 min in SC medium
Treatment protocol For RNA-seq, cultures were then either left untreated or exposed to 6 µg/ml SPB00525 and incubated at 30°C for 15- and 60-min. Cells were harvested by centrifugation and were flash-frozen and stored at -80°C. For each condition, a total of two biological replicates were considered for RNA-seq analysis. For the drug-induced haploinsufficiency profiling, the double-barcoded heterozygote C. albicans (DBC) mutant pools were diluted to OD600 = 0.062 and exposed or not to 6 µg/ml SPB00525 in either SC or YPD and grown at 30°C under agitation for 15 hours. 1 mL of the sub-cultured pool was distributed into triplicate culture tubes, each containing 1 mL of YPD or SC medium supplemented with either 6 µg/ml SPB00525 or DMSO solvent. These cultures were incubated at 30°C under shaking conditions for 24 hours.
Growth protocol For RNA-seq profiling, overnight cultures of C. albicans SC5314 and C. auris 381 strains were diluted to an OD600 of 0.1 in 50 ml of fresh SC medium and grown at 30°C under agitation (200 rpm) to early logarithmic phase (OD600=0.6).
Extracted molecule total RNA
Extraction protocol For RNA-seq, total RNA was extracted using an RNAeasy purification kit (Qiagen) and glass bead lysis in a Biospec Mini 24 bead-beater. For the drug-induced haploinsufficiency profiling, cells were harvested by centrifugation and genomic DNA was extracted using YeaStar kit (Zymo Research).
For RNA-seq, the NEBNext UltraTM II RNA Library Prep Kit for Illumina was used to construct the RNA-seq library. For the drug-induced haploinsufficiency profiling, the Up-tag DNA-barcodes were amplified using 25 ng genomic DNA with DBC-F1 and DBC-R1 primers that recognize the common region of up-tag barcode and contain the multiplexing tag (DBC-F1) and sequences required for hybridization to the Illumina flow cell. PCR amplification products were purified form an agarose gel using the QIAquick Gel Extraction kit (Qiagen) and quantified by QuantiFluor dsDNA System (Promega). Equal quantity of DNA from the SPB00525-treated and non-treated pools were combined prior to NGS sequencing using Illumina MiSeq platform and DBC1 and DBC2 sequencing.
 
Library strategy RNA-Seq
Library source transcriptomic
Library selection cDNA
Instrument model Illumina NovaSeq 6000
 
Data processing For RNA-seq, sequencing reads were filtered with fastp version 0.23.2.
For RNA-seq, filtered reads were mapped to the reference genome sequence of strain SC5314 and C. auris 381 with STAR version 2.7.9a
For RNA-seq, the number of reads mapping on each of the genes was calculated by featurecount version 2.0.1. For the drug-induced haploinsufficiency profiling , unique uptag DNA barcodes were extracted and counted using SeqKit
Differential gene expression and barcode abundance were calculated with DESeq2 version 1.26.0.
