Topography-dependent gene expression in migratory glioma cells

ABSTRACT: The goal of this experiment was to compare the gene expression of glioma cells migrating on substrates of different topographies and to determine a migration-associated gene profile. Human malignant glioma U251MG cells were cultured on highly-aligned versus randomly-oriented electrospun nanofibers of poly-caprolactone. Cells migrated actively on aligned nanofibers but motility was very restricted on randomly-oriented fibers. Results of gene expression profiling indicated upregulation of a JAK/STAT signature in actively migrating glioma cells. Total RNA was extracted from 3 independent cultures of U251 glioma cells cultured on aligned versus random nanofibers and applied to Affymetrix HG-U133 plus 2 chips. Analysis of gene expression was used to determine a gene-signature correlated with different substrate topography

Spatially patterned scaffolds enhances vascular organization and functional integration in volumetrc muscle loss

Project description:We report the application of bioengineered skeletal muscle composed of murine skeletal myoblasts interspersed with human vascular endothelial cells (ECs) using spatially patterned scaffolds for the treatment of volumetric muscle loss. To gain insights into the molecular mechanisms by which spatial patterning promoted myo-angiogenesis, we performed mRNA sequencing of engineered muscle and endothelialized engineered muscle on either randomly-oriented or aligned scaffolds. The goals of this study are to compare NGS-derived transcriptome profiling (RNA-seq) from four groups: 1) randomly-oriented scaffold seeded with myoblasts; 2) randomly-oriented scaffolds seeded with myoblasts + ECs; 3) aligned scaffold seeded with myoblasts only; 4) aligned scaffold seeded with myoblasts + ECs. Samples were generated in triplicate and the NovaSeq 6000 (Illumina) sequencing platform was utilized. 150-bp paired-end reads were generated (20-30 million reads per sample). The raw data were checked for quality with FastQC (Version 0.11.7) and results were aggregated with MultiQC and were aligned to the mouse genome (GRCm38) using STAR (Version 2.5.3a) with ENCODE options for long RNA-seq pipeline. The alignment results were assessed using Samtools and aggregated with MultiQC (Version 1.5) and the differential gene expression analysis of the uniquely mapped reads/raw counts wwas performed using the DESeq2 package (Version 1.20.0). Each DE analysis was composed of a pairwise comparison between an experimental group and the control group. Differentially expressed genes were identified after false discovery rate (FDR = 0.05) correction.

Pasha: a versatile R package for piling chromatin HTS data

Project description:We describe an R package designed for processing aligned reads from chromatin-oriented high-throughput sequencing experiments. Pasha (preprocessing of aligned sequences from HTS analyses) allows easy manipulation of aligned reads from short-read sequencing technologies (ChIP-Seq, FAIRE-seq, Mnase-Seq...) and offers innovative approaches to process and extract relevant information.

Bcl11a (Ctip1) controls migration of cortical projection neurons through regulation of Sema3c

Project description:During neocortical development, neurons undergo polarization, oriented migration, and layer type-specific differentiation. The transcriptional programs underlying these processes are not completely understood. Here we show that the transcription factor Bcl11a regulates polarity and migration of upper layer neurons. Bcl11a-deficient late-born neurons fail to correctly switch from multipolar to bipolar morphology resulting in impaired radial migration. We show that the expression of Sema3c is increased in migrating Bcl11a-deficient neurons and that Bcl11a is a direct negative regulator of Sema3c transcription. In vivo gain-of-function and rescue experiments demonstrate that Sema3c is a major downstream effector of Bcl11a required for the cell polarity switch and for the migration of upper layer neurons. Our data uncover a novel Bcl11a/Sema3c-dependent regulatory pathway used by migrating cortical neurons.

Modulation of glioma cell proteome by Delta-24-RGD adenovirus (24hpi)

Project description:Glioblastoma multiforme (GBM) is the most common and aggressive type of malignant glioma. Oncolytic adenoviruses are being modified to exploit the aberrant expression of proteins in tumor cells to enhance tumor tropism and glioma-selective replication. E1A mutant adenovirus Delta-24-RGD has shown favorable toxicity profile and remarkable efficacy in a first-in-human phase I clinical trial. However, the comprehensive modulation of glioma metabolism in response to Delta-24-RGD infection is poorly understood. Integrating mass spectrometry based-quantitative proteomics, physical and functional interaction data, and biochemical approaches, we conducted a cell-wide study of intracellular and secreted glioma proteomes at late stage of Delta-24-RGD infection, when prominent autophagy has been described.

Expression data from hiPSCs-NSCs towards U87

Project description:Neural stem cells can migrate towards tumors of both neural and non-neural origins, which is crucial for the success in treating disseminated tumors. Although the understanding of the molecular mechanisms underlying NSC tumor tropism is limited, it has been noted that several cytokines, growth factors and receptors direct the migration in vitro. A proper understanding of the basic molecular mechanisms of NSC migration towards tumors, especially identification of key cellular regulators of the migration, will have important implications in improving the effectiveness of engineering and employing NSCs as tumor therapy agents. We compared gene expression profiles between migratory and non-migratory hiPSC-NSCs towards cancer cells using cDNA microarray profiling. We collected human iPSCs derived NSCs migrating and not migrating towards human U87 glioma cells in an in vitro migration system for total RNA extraction and hybridization to Affymetrix microarrays

CELL CONTRACTILITY AND AN ACTIN GRADIENT DRIVE POLAR ALIGNMENT OF FIBROBLASTS IN CONSTRAINED GEOMETRIES

Project description:When REF 2c cells were placed on circular micro-contact printed patterns, the boundary cells radially aligned over a period of 48 h. Video tracking of specific boundary and inner cells showed that this phenomenon was not caused by cells migrating towards or away from the periphery. Cell contractility, intercellular junctions, and cell-cell adhesion are required for radial alignment.

Map of the Kir2.1 interactome using BioID

Project description:Kir2.1, an inward rectifier potassium channel, plays an important role in controlling membrane potential specially in cardiomyocytes. Here we explore its interactome via proximity biotin labeling and affinity purification approach (BioID). First, BioID membrane controls were generated with randomly selected transmembrane domains from yeast proteins, demonstrating the identification of membrane-associated proteins more than GFP or NLS controls. Using this control and a mutation from Andersen-Tawil syndrome which causes Kir2.1 Golgi accumulation, we have identified the most comprehensive Kir2.1 interactome and also found clues to its spatial information in subcellular levels. The interactome is showing that Kir2.1 in plasma membrane is surrounded by desmosome, integrin, cadherin and dystrophin-glycoprotein complex complexes, and supported by MAGUK family scaffold proteins. On the other hand, Kir2.1 mutant BioID revealed the COPII-mediated delivery of Kir2.1 from ER to Golgi and lysosome-mediated degradation of Golgi-accumulated and/or retrograde Kir2.1. Validating the interactome with co-immunoprecipitation, confocal microscope, and patch clamp analysis, we concluded that Kir2.1 is located in the defined membrane environment and is actively regulated by endosomal sorting for lysosome degradation.
