Sample GSM2831502 Query DataSets for GSM2831502
Status Public on Dec 20, 2017
Title tumor from scrambled siRNA-treated mouse #4819 [miRNA]
Sample type RNA
Source name patient-derived xenograft tumor from scrambled siRNA-treated mouse #4819
Organism Homo sapiens
Characteristics tissue: breast cancer tumor tissue
genotype: Triple-negative breast cancer
xenograft type: BCM2665
Treatment protocol Groups (0) and (1) (n=10) were treated with 5 µg/mouse DOPC nanoliposomal siRNA IP injection twice a week for 3 weeks. Mice were sacrificed on day 21. Tumors were harvested and snap frozen.
Growth protocol In docetaxel-resistant BCM2665 PDX xenografts, tumors were transplanted into the mammary fat pad of SCID-Beige mice. Mice were randomized into 5 groups when tumor volume reached 150-200mm3: (0)scrambled siRNA, (1)HN1L siRNA.
Extracted molecule total RNA
Extraction protocol Extraction of miRNA from each frozen tumor sample was performed using miRNeasy Mini kit from Qiagen following manufacturer instruction.
Label biotin
Label protocol Biotinylated miRNA were prepared according to the standard Affymetrix protocol.
Hybridization protocol hybridization,washing and staining were done following Affymetrix protocol for Genechip miRNA 4.0 arrays.
Scan protocol Scanning was done on Affymetrix Genechip Scanner model 7G, Affymetrix Genechip command console(AGCC) software was used for instrument control, data acquisition and quality control.
Description miRNA expression data from TNBC tumor sample of scramble-siRNA treated mouse model BCM2665
Data processing Expression values were processed and normalized using the affy library in R statistical software. Only human probes were isolated, from the multispecies miRNA profiling by the miRNA array 4.0, for the purpose of the analysis. Differential expression analysis was then performed using limma package in R. The most significantly differentially expressed miRNAs were selected based on a cut off log fold change > 1 and FDR < 0.2.
