Sample GSM4055266 Query DataSets for GSM4055266
Status Public on Jul 31, 2020
Title Time 24_Control_Rep 3 (reanalysis)
Sample type RNA
 
Source name Nf54 attB parasites,Time 24, Rep 3
Organism Plasmodium falciparum
Characteristics tissue: Blood-stage Nf54 attB P. falciparum parasites cultured in human erythrocytes at 2% hematocrit
time: Time 24
treatment: Control
slide id (array batch): 253723710162
replicate: Rep 3
Treatment protocol The CLD-PyrKII parasite line was synchronized via magnetic purification and used to seed a 50mL culture flask at 1% parasitemia and 2% hematocrit. Six hours post synchronization (mid-schizogeny) 500nM Shield1 was added, representing time 0. Media containing 500nM Shield1 was replaced at 16 hours and every 24 hours thereafter.
Growth protocol Blood-stage P. falciparum parasites were cultured in human erythrocytes at 2% hematocrit in CMA (Complete Medium with Albumax) containing RPMI 1640 medium with L-glutamine (USBiological Life Sciences), supplemented with 20mM HEPES, 0.2% sodium bicarbonate, 12.5μg/ml hypoxanthine, 0.5μM R-lipoic acid, 5g/L Albumax II (Life Technologies) and 25μg/mL gentamicin. Cultures were maintained in 25cm2 gassed flasks (94% N2, 3% O2, 3% CO2) and incubated at 37°C.
Extracted molecule total RNA
Extraction protocol For each data point, RNA was extracted from 100 µL of packed RBC culture with Trizol Reagent and the PureLink Mini Kit (Invitrogen/Thermo Fisher Scientific). 1ml Trizol was added to each sample, followed by high-speed disruption in tubes containing Lysing Matrix D (MP Biomedical) in a FastPrep 120 Instrument at speed 6 for 20 seconds. Homogenates were subsequently processed according to the PureLink Mini Kit manufacturer’s (Invitrogen/Thermo Fisher Scientific) protocol, including on-column DNase treatment.
Label Cy3
Label protocol From 100 ng of total RNA, Cyanine-3 labeled cRNA was prepared using the Low Input Quick Amp Labeling Kit One-Color (Agilent).
 
Hybridization protocol The eight time course samples were hybridized (along with the manufacturer’s RNA spike-in controls) according to standard protocol to the 8 sectors of an Agilent 8x15K platform microarray (AMADID 037237) with separate microarray slides used for each biological replicate (in triplicate for each treatment condition).
Scan protocol Arrays were scanned with the Agilent G2600D SureScan microarray scanner using scan protocol AgilentHD_GX_1color. Agilent’s Feature Extraction Software was used to assign grids, provide raw image files per array, and generate QC metric reports from the microarray scan data.
Description Gene Expression Data
Data processing Txt files from the Feature Extraction software were imported into the Partek Genomics Suite (v7.0; Partek) for detailed analyses of gene expression. Within Partek, the gProcessedSignal was imported, and the intensity values were normalized to the 75th percentile, lower expressed genes were filtered out using a max cutoff of <=0.5, and log transformation base 2.0 was performed.
