Sample GSM4483911 Query DataSets for GSM4483911
Status Public on May 31, 2020
Title MDA-MB-231-205-5p Rep2
Sample type RNA
Source name MDA-MB-231-205-5p
Organism Homo sapiens
Characteristics cell line: MDA-MB-231
cell type: Breast cancer cell line
miRNA: has-miR-205-5p precursor
Treatment protocol MDA-MB-231 cells (0.168 x 10e6 cells/ml) were transfected with the selected miRNA precursors (pre-miR–negative control, hsa-miR-205-5p and hsa-miR-214-3p) purchased from Ambion. Cell transfection was conducted employing a reverse transfection protocol.
Growth protocol MDA-MB-231 cells were grown in DMEM supplemented with 10% fetal bovine serum, 1% NEAA, 1% L-glutamine, 100 mg/l penicillin, and 100 mg/l streptomycin.
Extracted molecule total RNA
Extraction protocol Total RNA were isolated from control and treated cells using Total RNA Purification Kit (Norgen-Biotek Corp., Canada) according to the manufacturer’s instructions. The concentrations of total RNA were measured using NanoDrop 2000 (Thermo-Scientific).
Label Cy3
Label protocol Cyanine-3 (Cy3) labeled cRNA was prepared from 100 ng RNA using the Low Input Quick Amp Labeling Kit, one-color (Agilent) according to the manufacturer's instructions, followed by RNeasy column purification (QIAGEN, Valencia, CA). Dye incorporation and cRNA yield were checked with the NanoDrop ND-2000 Spectrophotometer.
Hybridization protocol 1.65 ug of Cy3-labelled cRNA was fragmented at 60°C for 30 minutes in a reaction volume of 55 ul following the manufacturer’s instructions. On completion of the fragmentation reaction, 55 ul of 2× Hi-RPM Hybridization Buffer (Agilent) was added to the fragmentation mixture and hybridized to Agilent Whole Human Genome GE 4x44K v2 Microarray chip for 17 hours at 65 °C in a rotating Agilent hybridization oven. After hybridization, microarrays were washed 1 minute at room temperature with GE Wash Buffer 1 (Agilent) and 1 minute with 37 °C GE Wash buffer 2 (Agilent), then dried immediately.
Scan protocol Slides were scanned immediately after washing on the Agilent DNA Microarray Scanner (G2505C) using one color scan setting for 8x60k array slides.
Description Gene expression in MDA-MB-231 breast cancer cell line transfected with has-miR-205-5p precursor replica 2.
Data processing The scanned images were analyzed with Feature Extraction Software 11.0 (Agilent) using default parameters. Data were analyzed using Agilent GeneSpring X software.
