ADAR1 overexpression in MDA-MB-231 cells

ABSTRACT: Abstract: RNA editing has emerged as novel mechanisms involved in cancer progression. Despite the phenotypic implications of ADAR in several cancer models, the role of ADAR on DNA damage response (DDR) and proliferation in breast cancer (BC) has not been fully addressed. To evaluate the effect of ADAR expression, MDA-MB-231 cells were transduced (MOI:200) with commercial pre-package adenoviral particles coding for ADARp110 or transduced (MOI:200) with eGFP control adenovirus. 16 h after transduction media was changed and RNA were extracted 48 h after transduction. ADARp110 overexpression produces a significant increase in transcripts related with cell cycle and proliferative pathways, in addition to other pathways related to IL10 signaling, among others. In other hand 657 sites significantly increase their editing in MDA-MB-231 OV cells at site level comparison. Conversely, transcripts involved in Generic Transcription, cell cycle, HIV life Cycle related pathways and Apoptosis suffer an increased editing ratio, suggesting that ADAR activity could be is in the regulation of the targets that bears significant changes in their editing pattern after ADAR manipulation

Knockdown of Znf148 by shRNA in MDA-MB-231 breast cancer cells.

Project description:RNA-Sequencing of basal subtype triple negative breast cancer cells, MDA-MB-231. MDA-MB-231 cells were lentivirally transduced with pLKO short-hairpin (sh) luciferase control or shZnf148 in triplicates. Differentially expressed genes by the shRNA compared to the control were determined.

Neuropilin-1 Knockout and Rescue Confirm its Role to Promote Metastasis in MDA-MB-231 Breast Cancer Cells

Project description:To investigate the function of Neuropilin-1 (NRP-1) in breast cancer MDA-MB-231 cells. CRISPR-Cas9 gene editing was used to knockout (KO) the NRP-1 gene in MDA-MB-231 human triple-negative breast cancer cells. Differentially expressed genes (DEGs) were determined in NRP-1 KO and parental MDA-MB-231 cells using whole transcriptome next-generation sequencing.

RNAPolII CUT&Tag profiles of MDA-MB-231 cell line with repression of CDK genes and PRMT5

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.

Tang2019 - Pharmacology modelling of AURKB and ZAK interaction in TNBC

Project description:Aurora Kinase B and ZAK interaction model Equivalent of the stochastic model used in "Network pharmacology model predicts combined Aurora B and ZAK inhibition in MDA-MB-231 breast cancer cells" by Tang et. al. 2018. The only difference is cell division and partitioning of the components, which are available in the original model for SGNS2.

Gene expression profile in breast cancer cells

Project description:We report the gene expression patterns in MDA-MB-231 (a line selected for low metastatic ability), MDA-MB-231-1833 (its bone-tropic metastatic derivative line), MDA-MB-231p27CK-DD (a phosphomimetic cell line), MDA-MB-231-1833shp27 (p27 knockdown cell line), MDA-MB-231-1833PF1502 (PI3K inhibitor treatment). It shows that the gene expression pattern are regulated in a p27 phosphorylation-dependent manner.

LncRNA Uc003xsl.1 Activates of NF-κB/IL8 Axis to Promotes Triple-negative Breast Cancer Progression via A Decoy Role to NKRF [lnc231]

Project description:To discover the potential drivers of TNBC metastasis, we established an in vivo model by injecting MDA-MB-231cells into the tail veins of mice. Then, the breast tumor cells that successfully grew into metastatic lung tumors were collected and expanded in vitro, followed by re-injected into the tail veins of mice for lung metastasis. After three rounds of selection, a highly metastatic subline, MDA-MB-231-P3, was established, and more frequent micro-metastasis was detected in MDA-MB-231-P3 groups than that of MDA-MB-231 groups when the lungs of mice were stained with hematoxylin and eosin (HE). The lncRNA profiles of MDA-MB-231 or MDA-MB-231-P3 cells were analyzed by lncRNA sequencing. A total of 267 lncRNAs in MDA-MB-231-P3 cells were upregulated more than 2-fold in comparison to the MDA-MB-231 cells.

Project description:RNAi screens via pooled short hairpin RNAs (shRNAs) have recently become a powerful tool for the identification of essential genes in mammalian cells. We synthesized DNA microarrays with six overlapping 25 nt long tiling probes complementary to each unique 60 nt molecular barcode sequence associated with every shRNA expression construct.. In this part of the study pooled shRNAs were transduced into MDA-MB-231 breast carcinoma cell lines and their inhibitory effects four weeks post transduction were analyzed via microarray hybridization.
