Sample GSM4477466 Query DataSets for GSM4477466
Status Public on Apr 06, 2021
Title Total RNA Rep2
Sample type SRA
 
Source name HEK293 cells expressing P301S-tau RD -YFP and P301S-tau RD-CFP
Organism Homo sapiens
Characteristics transfection_status: Transfected with clarified brain homogenate from P301S mice
genotype: HEK293 Tau-RD-P301S-CFP/YFP
cell line: HEK293
sample: total RNA
Treatment protocol 200 ug of WT or P301S tau clarified mouse brain homogenate was transfected per dish using lipofectamine 2000 and incubated at 37C for 24 hours. Tau aggregation was monitored using the Evos M500 Imaging System with a GFP filter. Cells were harvested by scraping, centrifuged at 1500g, snap frozen in liquid nitrogen, and stored at -80C.
Growth protocol HEK293 biosensor cells were grown to 70-80% confluency in 245 mm square tissue culture treated dishes (Corning 07-200-599) in 50mL of DMEM (one plate per biologic replicate).
Extracted molecule total RNA
Extraction protocol large tau aggregates were enriched for by differential centrifugation and then further purified using fluroescence automated particle sorting. Tau aggregates were denatured and RNA was isolated from all samples using proteinase K, Guanadinium HCL, and Trizol LS reagent.

Description Random hexamer primed RNA
Data processing Timmomatic 0.36 to trim Illumina TruSeq3 adapters and low quality reads (options: 2:30:10 LEADING:3 TRAILING:3 SLIDINGWINDOW:4:15 MINLEN:36)
Ribosomal reads were filtered out by mapping to a ribosome reference genome (UCSC hg38 humRibosomal.fa) and keeping the unmapped reads.
Reads were then mapped to GRCh38 using STAR v2.6.0c in two pass alignment mode with --outFilterMultimapNmax 20)
FPKM was calculated using the longest transcript lengths taken from from ensembl biomart GRCh38.p13
