Effect of knock down of LASP-1 on luminal breast cancer cells (MCF7)

ABSTRACT: Nuclear LASP-1 has a direct correlation with the overall survival of breast cancer patients. Gene expression analysis of MCF7 human breast cancer cells cultured in 3D-Matrigel was performed. Up regulation of cell junction proteins, extracellular matrix proteins and down regulation of MMP 9 and 2 were observed. This corroborates well with the involvement of LASP-1 in cell migration and chemotaxis. Non-silencing (control) and LASP-1 knock down MCF7 cells were cultured on 3D-Matrigel, total RNA was extracted and anlyzed - 4 biological replicates each. The first biological replicate was done as a pilot. Biological replicates 2-4 were run as a second set after pilot.

Nuclear LASP-1 (LIM and SH3 protein-1) has a direct correlation with overall survival of breast cancer patients. In this study, immunohistochemical analysis of a human breast TMA showed that LASP-1 is absent in normal human breast epithelium but the expression increases with malignancy and is highly nuclear in aggressive breast cancer. We investigated whether the chemokines and growth factors present in the tumor microenvironment could trigger nuclear translocation of LASP-1.Treatment of human b ...[more]

Transcriptional characterization of Human Lung Organoids (HLOs) using RNAseq

Project description:Human lung organoids (HLOs) were derived from human embryonic stem cell line H9 NIH registry #0062. Sequencing of HLOs was performed by the UM DNA Sequencing Core, using Illumina Hi-Seq platform and single-end 50 bp reads. The UM Bioinformatics Core downloaded the reads files from the Sequencing Core storage, and concatenated those into a single .fastq file for each sample. 3 HLOs were cultured for 65 days and 3 HLOs were cultured in vitro for 110 days. HLO Culture Protocol 4-day Activin A (R&D systems) differentiation protocol was used to derive definitive endoderm from human pluripotent stem cells (hPSCs). Cells were treated with Activin A (100ngml-1) for three consecutive days in RPMI 1640 media (Life Technologies) with increasing concentrations of 0%, 0.2% and 2% HyClone defined fetal bovine serum (dFBS, Thermo Scientific). The fourth day was a repeat of day 3 media (2% HyClone FBS). After differentiation into definitive endoderm, cells were incubated in foregut media (advanced DMEM/F12 plus N-2 and B27 supplement, 10mM Hepes, 1x L-Glutamine (200mM), 1x Penicillin-streptomycin (5,000 U/mL, all from Life Technologies)) with 200ng/mL Noggin (NOG, R&D Systems) and 10uM SB431542 (SB, Stemgent) for 4 days, SB, 500ng/mL FGF4 (R&D Systems), and 2 uM CHIR99021 (Chiron, Stemgent), and 1uM SAG (Enzo Life Sciences) for 4-6 days. After 4 days with treatment of growth factors, three-dimensional floating spheroids were present in the culture. Three-dimensional spheroids were transferred into Matrigel to support 3D growth. Spheroids were embedded in a droplet of Matrigel (BD Bioscience #356237) in one well of a 24 well plate, and incubated at room temperature for 10 minutes. After the Matrigel solidified, foregut media with 1% Fetal bovine serum (FBS, CAT#: 16000-044, Life Technologies) and 500ng/mL FGF10 (R&D Systems) were overlaid and replaced every 4 days. Organoids were transferred into new Matrigel droplets every 10 to 15 days.

Gene expression analysis of MCF7 breast cancer cells cultured as xenografts, in two dimensional cultures, in polyHEMA anchorage independent three dimansional cell culture models and in Matrigel three dimensional cultures.

Project description:The traditional method for studying cancer in vitro is to grow immortalized cancer cells in two-dimensional (2D) monolayers on plastic. However, many cellular features are impaired in these unnatural conditions and big alterations in gene expression in comparison to tumors have been reported. Three-dimensional (3D) cell culture models have become increasingly popular and are suggested to be better models than 2D monolayers due to improved cell-to-cell contacts and structures that resemble in vivo architecture. The aim of this study was to compare gene expression patterns of MCF7 breast cancer cells when grown as xenografts, in 2D, in polyHEMA coated anchorage independent 3D models and in Matrigel on-top 3D cell culture models. Surprisingly small variations in gene expression patterns were observed between the models indicating that 3D and xenograft are not always that different from 2D cell cultures. Gene expression analysis of MCF7 breast cancer cells cultured as xenografts for 43 days, in two dimensional cultures for seven days (2D7d), in polyHEMA three dimensional cell culture models for four and seven days (PH7d and PH7d), and in Matrigel three dimensional cultures for four and seven days (MG4d and MG7d). Two biological replicates was included for each sample.

RNA-seq analysis of several in vitro models of hepatocyte function: Project 4 of Open Targets - Epigenomes of Cell Lines

Project description:The aim of this experiment was to characterize the gene expression of several in vitro cellular models of hepatocyte function: primary hepatocytes and common immortalized liver cell lines (HepG2, Hep3B and Huh7), cultured in parallel in both 2D and 3D configurations. Two independent cultures were carried out for each of the cell lines. For primary cultures, cells were obtained from three independent donors and cultured in parallel in both conditions. For the 2D culture, cell lines were grown using standard culture methods and harvested sub-confluence in exponential growth phase. For the 2D culture of primary hepatocytes, cells were grown in sandwich configuration between two layers of extracellular matrix (collagen coated plates and medium containing 0.25mg/ml Matrigel) and harvested at day 9 post seeding. For 3D cultures, cells were seeded at 1500 cells per well in ultra-low adherence multi-well plates to facilitate cellular aggregation and spheroid formation. Cell line spheroids aggregated rapidly and were harvested 4-5 days post seeding. Primary cell spheroids formed more slowly and were harvested 14-17 days post seeding. This RNA-seq experiment is being carried out as part of the Open Targets project to identify a gene expression signature of common immortalized cell lines/models. This signature will be used in combination with data from ChIP-seq experiments from the same cell lines against primary cells and tissues. The overall aim of the Open Targets Cell Line Epigenome project is to establish a systematic approach for the determination of human biological and disease relevance through the generation of transcriptomic and epigenomic data in cell lines of interest. Comparison of cell line mRNA expression and epigenome data with existing and newly generated reference data from human tissue and cell types will identify assay systems that will provide greater confidence in translating target biology and compound pharmacology to patients.
