Sample GSM5594357 Query DataSets for GSM5594357
Status Public on Mar 06, 2022
Title 3D7_AP2-HC-KO_S_RNA-seq, Rep3
Sample type SRA
 
Source name schizont (40-45 hpi)
Organism Plasmodium falciparum
Characteristics tissue: whole body
developmental stage: schizont (40-45 hpi)
strain: Pf 3D7
genotype: AP2-HC-KO
host: Homo sapiens
Treatment protocol Parasites were tightly synchronized to a 6-hour window by isolating schizonts over a 40% and 70% Percoll-sorbitol gradient followed by sorbitol treatment 6 hours post re-invasion.
Growth protocol Parasites were cultured in fresh O-type human erythrocytes in complete RPMI 1640 medium (Gibco) with 0.5% Albumax I (Invitrogen) and a gas phase maintained under 5% CO2, 5% O2 and 90% N2 at 37°C.
Extracted molecule total RNA
Extraction protocol Highly synchronous parasites were collected in TRIzol at the ring (10-15 hpi), trophozoite (25-30 hpi), and schizont (40-45 hpi) stages from the next cycle, respectively. Total RNA purification was conducted with the Direct-zol RNA Kit (Zymo Research).
Libraries were prepared for strand-specific RNA sequencing by poly(A) selection with the KAPA mRNA Capture Beads (KAPA Biosystems) first and then RNA fragmentation to a size of 300-400 nucleotides. Subsequent library preparation steps followed the protocol of the KAPA Stranded mRNA-seq Kit Illumina platform (KAPA Biosystems, KK8421).
 
Library strategy RNA-Seq
Library source transcriptomic
Library selection cDNA
Instrument model HiSeq X Ten
 
Data processing To remove residual adapters and low-quality bases, sliding window trimming was performed on reads with Trimmomatic v0.39 using a window size of 4 and average quality of the window above 15. A minimum read length of 50 bp and average read quality above 20 were required after read clipping.
HISAT2 v2.2.1 was employed to align trimmed RNA-seq reads to the P. falciparum 3D7 reference genome (release 47) with the guide by the gene annotation, using default parameters except --max-intronlen 5000 --dta --rna-strandness RF.
StringTie v2.1.2 was used to count reads mapped to each gene.
