Project description:The mammalian target of rapamycin (mTOR) is a central regulator of cell proliferation. Inhibitors of mTOR are being evaluated as anti-tumor agents. Given the emerging role of microRNAs (miRNAs) in tumorgenesis we hypothesized that miRNAs could play important roles in the response of tumors to mTOR inhibitors. Rapamycin resistant myogenic cells developed by long-term rapamycin treatment showed extensive reprogramming of miRNAs expression, characterized by up-regulation of the mir-17~92 and related clusters and down-regulation of tumor-suppressor miRNAs. Antagonists of oncogenic miRNA families and mimics of tumor suppressor miRNAs (let-7) restored rapamycin sensitivity in resistant tumor cells. This study identified miRNAs as new downstream components of the mTOR-signaling pathway, which may determine the response of tumors to mTOR inhibitors. Total RNA extraction and hybridization on Affymetrix microarrays of rapamycin sensitive (RS) cells (BC3H1, mouse brain tumor cell line with myogenic properties, ATCC) cultured in Dulbecco’s modified essential medium (DMEM) media supplemented with 20% fetal bovine serum (FBS), penicillin (100 U/ml) and streptomycin (100 mg/ml). Rapamycin resistant cells (RR1) were developed by culturing BC3H1 cells in the presence of 1 uM rapamycin for 6 months. Three samples in triplicates: 1) Rapamycin sensitive cells treated with DMSO for 24 h(BC3H1, reference), 2) Rapamycin sensitive cells treated for 24 h with 100 nM rapamycin (BC3H1+R), 3) Rapamycin resistant cells constantly treated with 1uM Rapamycion (RR1+R).

Project description:NCI-H2030 lines were seeded in 6-well plates in complete culture medium and cultured at densities allowing exponential growth: 50000 cells/well. After 24 h, compounds were added (DMOS, adagrasib (30 nM), K-975 (100 nM) and adagrasib (30 nM)+K-975 (100 nM)) at a final percentage of 0.2% DMSO. Twenty-four hours after compounds addition, cells were used for transcriptomic profiling.
Project description:The RAW264.7 cells (2x105 cells/ml) were seeded in 100 mm cell culture dishes in DMEM containing 10% FBS. When the cell density reached 70%, cells were infected with B. abortus A19 (MOI=200) for 4 h, and the cell medium then was changed to DMEM containing 10% FBS with gentamicin (50 ng/μl) for 1 h. The medium subsequently was changed to DMEM containing 10% FBS with gentamicin (25 ng/μl) for 24 h at which time cells were harvested and placed at -80°C. Subsequently, the cells lysates were analyzed by protein liquid chromatography-mass spectrometry (LC-MS/MS)

Rapamycin resistant cells (RR1) were developed by culturing BC3H1 cells in the presence of 1 uM rapamycin for 6 months. Three samples in quadruplicate 1)RS cells treated with DMSO for 24 h(BC3H1, reference), 2) RS cells treated for 24 h with 100 nM rapamycin (BC3H1+R), 3) RR1 cells consantly treated with 1uM Rapamycion (RR1+R). For each experiment, 1 μM of total RNA was labeled with Hy3TM dye and a reference RNA pool (consisting of a mixture of equal amounts of total RNA from BC3H1, BC3H1+R and RR1+R cells) was labeled with Hy5TM dye using the miRCURYTM Labeling Kit. The samples were hybridized to Exiqon miRCURYTM LNA Arrays (V10.0).
Project description:A clonal doxycycline inducible dCas9-KRAB MDA-MB-231 cell line to control repression of CDK genes and PRMT5. On day 1 of the experiment cells were infected with lentiviruses containing the appropriate targeting/NTC sgRNAs driven by the human U6 promoter at an MOI of ~3 for each virus to ensure all cells were transduced. Cells were transduced in DMEM + 10% FBS with the addition of 8 μg/mL polybrene. 16 hours after the time of transduction, media was changed to DMEM +10% FBS. 24 hours after this, the cell culture media was switched to DMEM + 10%FBS containing 2μg/mL puromycin to ensure no uninfected cells remain. 48 hours after this, cell culture media was changed to DMEM + 10%FBS containing 2 μg/mL puromycin and 1 μg/mL doxycycline to induce dCas9-KRAB expression. 48 hours after this, cells were processed for CUT&Tag library prep following the manufacturer's recommendations.
