Single cell RNA-seq revealed critical genetic programs of invasive fibroblasts for pulmonary fibrosis

ABSTRACT: We performed a single cell RNA-seq survey of 14,704 invasive fibroblasts and 16,104 non-invasive fibroblasts using an in vitro assay system which had been previously used to evaluate the ability of lung fibroblasts to spontaneously invade Matrigel and commonly used to analyze the metastatic potential of cancer cells. Different subtypes in invasive or non-invasive lung fibroblasts were classified, and their gene signatures, specific cell surface markers, long non-coding RNA (lncRNA), key transcription factors and signaling pathways were further confirmed mechanistically and functionally. After combination of all the specific genes for Ingenuity Pathway Analysis (IPA), we found that the ERBB2 (HER2) signaling pathway was significantly activated in invasive fibroblasts and was markedly inhibited in non-invasive fibroblasts.

The differential gene screening for invasive pituitary adenoma and non-invasive pituitary adenoma

Project description:Pituitary adenomas are benign tumors originating from the endocrine cells of the pituitary gland, but some pathological subtypes are highly invasive, known as invasive pituitary adenomas. Invasive pituitary adenomas are relatively rare, progress rapidly, easily invade surrounding tissues, have a high risk of recurrence, and have poor response to standard treatments. This study collected tumor specimens from 17 patients with non-invasive pituitary adenomas (FSH type) and 15 patients with invasive pituitary adenomas (ACTH-silent type), and performed transcriptome sequencing, aiming to explore the genetic differences between invasive and non-invasive pituitary adenomas.

CpG Methylation profile of Invasive Pancreatic Cancer Cells compared to Non-invasive

Project description:Two established cell lines, PANC1 and HPAC, were invaded toward a stem cell media through Matrigel. DNA was isolated from Non-invasive cells and invasive cells. Methylated DNA was isolated from each sample using the Methyl Collector kit from Active Motif. Methylated and Non-Methylated DNA was dye labeled and applied to 244K Human promoter tiling arrays.

Identification of p130Cas/ErbB2-dependent invasive signatures in transformed mammary epithelial cells

Project description:Understanding transcriptional changes during cancer progression is of crucial importance to develop new and more efficacious diagnostic and therapeutic approaches. It is well known that ErbB2 is overexpressed in about 25% of human invasive breast cancers. We have previously demonstrated that p130Cas overexpression synergizes with ErbB2 in mammary cell transformation and promotes ErbB2-dependent invasion in three-dimensional (3D) cultures of human mammary epithelial cells. Here, by comparing coding and non-coding gene expression profiles, we define the invasive signatures associated with concomitant p130Cas overexpression and ErbB2 activation in 3D cultures of mammary epithelial cells. Specifically, we have found that genes involved in amino acids synthesis (CBS, PHGDH), cell motility, migration (ITPKA, PRDM1), and angiogenesis (HEY1) are upregulated, while genes involved in inflammatory response (SAA1, S100A7) are downregulated. In parallel, we have shown that the expression of specific miRNAs is altered. Among these, miR-200b, miR-222, miR-221, miR-R210, and miR-424 are upregulated, while miR-27a, miR-27b, and miR-23b are downregulated. Overall, this study presents, for the first time, the gene expression changes underlying the invasive behavior following p130Cas overexpression in an ErbB2 transformed mammary cell model. To identify transcriptional changes occurring during invasion we have performed a comparative microarray analysis of non coding RNA (miRNA) between MCF10A.B2 acini over-expressing p130Cas with activation of ErbB2 and control cells.

Transcriptional profiling and comparative genomic analysis of an invasive and non-invasive strain of Candida albicans

Project description:Invasion of host tissue by the human fungal pathogen, Candida albicans is an important step during many forms of candidosis. However, not all C. albicans strains possess the same invasive and virulence properties. It is known for example that the two clinical isolates SC5314 and ATCC10231 differ in their ability to invade into host tissue and to cause infections. Strain SC5314 is invasive whereas strain ATCC10231 is non-invasive and strongly attenuated in virulence as compared to SC5314. In this study we compare the in vitro transcriptional profiles and the genotypic profiles of these two widely used laboratory strains in order to determine the principal biological and genetic properties which may govern the different potential for invasiveness and virulence. Keywords: transcriptional profiling, comparative genomic hybridisation, invasive vs. non-invasive C. albicans strain
