Sample GSM3068138 Query DataSets for GSM3068138
Status Public on Apr 06, 2018
Title INS-KD rep2
Sample type SRA
Source name EndoC βH1
Organism Homo sapiens
Characteristics cell type: Pancreatic Beta cells
treatment: shRNA induced
cell line: EndoC BetaH1
Treatment protocol A lenti-viral system were used to deliver shRNA construct into EndoC-βH1 cells. To performing knockdown experiments, the viral transduced cells were treated with 1 mg/mL doxycycline for 7 days. ). The media was changed every 48 h. No doxycycline was added in the negative control samples.
Growth protocol EndoC βH1 cells were grown in were cultured in low-glucose Dulbecco's modified Eagle's medium (Life Technology, cat. # 11885) with 2% BSA (fatty acid free and heat shocked, Equitech, cat. #BAH66), 50 μM 2-mercaptoethanol, 10 mM nicotinamide, 5.5 mg/ml human transferrin (Sigma–Aldrich, cat. #T8158), 6.7 ng/ml sodium selenite, 100 U/ml penicillin, and 0.1 mg/ml streptomycin. Cells were seeded at a density of 6 × 10^5/cm2 on ECM-gel (1%) (Sigma-Aldrich, cat. # E1270) /fibronectin (2 µg/ml; Sigma–Aldrich, cat #. F1141) coated plates and cultured at 37 °C and 5% CO2.
Extracted molecule total RNA
Extraction protocol The total RNA from 5 × 10^5 EndoC-βH1 cells that were induced with shRNA was isolated with a NucleoSpin RNA XS kit (Clontech).
The c-DNA library was prepared with a SMART-Seq® v4 Ultra® Low Input RNA Kit (Clontech, Cat. #634888) with 10 ng input RNA. The full-length cDNA output of the SMART-Seq v4 Ultra Low Input RNA Kit for Sequencing was processed with the Nextera XT DNA Library Preparation Kit (Illumina, Cat. # FC-131-1024).
