Sample GSM7766062 Query DataSets for GSM7766062
Status Public on May 24, 2024
Title G_Phe
Sample type SRA
Source name Islets of Langerhans
Organism Mus musculus
Characteristics tissue: Islets of Langerhans
age: 12-weeks
cell type: Beta-cells and alpha-cells mainly
genotype: C57BL/6NRj mice
treatment: Phe-GAA-5'
Treatment protocol Dissociated mouse islet cells were transfected using Lipofectamine 2000 (Thermo Fisher) with scramble control oligonucleotides or specific tRF mimics for LysCTT-5’, PheGAA-5’ and SerGCT-3’ (Integrated DNA Technologies). RNA was collected in Qiazol (Qiagen), 48h after transfection
Growth protocol Mouse pancreases from C57BL/6NRj mice were digested with collagenase (Sigma), and islets isolated by Histopaque (Sigma) density gradient and handpicking. Purified islet cells were cultured in RPMI 1640 GlutaMAX medium (ThermoFisher) supplemented with 10% FCS, 100 U/mL penicillin and 100 µg/mL streptomycin, 1 mM sodium pyruvate (Sigma), and 10 mM Hepes (Sigma). Rodent islets were dissociated into single cells by incubation in Ca2+/Mg2+free phosphate-buffered saline, 3 mM EGTA, and 0.002% trypsin (ThermoFisher) for 2-3 min at 37 °C and cultured 24h before treatment.
Extracted molecule total RNA
Extraction protocol RNA was extracted with miRNeasy kit (Qiagen).
