Long non-coding RNA HOTAIR is expressed in small cell lung cancer and is relevant to cellular proliferation, invasiveness and clinical relapse: tissue and cell-line analyses

ABSTRACT: LincRNA HOTAIR was expressed in pure SCLC and higher expression was significantly related to lymphatic invasion and relapse. Multivariate analyses demonstrated that HOTAIR expression correlated with RFS. In vitro experiments demonstrated that half of SCLC cell lines expressed HOTAIR at higher levels than normal cells and that, using cells of SBC-3, knockdown of HOTAIR decreased proliferative activity and cellular invasiveness with altered expression of cell adhesion-related genes. Total RNAs from one siHOTAIR-transfected SBC-3 cells and control cells (siGFP-transfected cells), were extracted using RNeasy mini kit Plus (Qiagen) and hybridized to the microarrays, Sure Print G3 Human GE 8x60K microarrays (Agilent Technologies, Santa Clara, CA, USA), according to the manufacturerM-bM-^@M-^Ys instructions. Subsequently, data analysis was carried out using the GeneSpring GX 12 software (Agilent Technologies), with a stringency of P<0.1 and a 2-fold or more change using gene ontology analysis.

Global gene expresion profile of phenotypically distinct human mammary epithelial subpopulations of various developmental age

Project description:To get molecular insight into age- and compartment-specific changes in telomere maintenance and associated properties in human mammary gland, we analyzed distinct subsets of normal human mammary epithelial cells. The cells were isolated by fluorescent activated cell sorting (FACS) directly from mammary tissue obtained from normal women undergoing reduction mammoplasties with concomitant removal of hematopoietic and endothelial cells by depletion of CD45pos and CD31pos cells. The three epithelial cell populations then isolated were: (i) CD49fhiEPCAMneg/low cells, (ii) CD49fposEPCAMpos cells and (iii) CD49fnegEPCAMpos cells. The CD49fhiEPCAM-/low cells are selectively enriched in mammary stem cells with functional mammary gland regenerating activity in suitably transplanted immunodeficient mice, bipotent progenitors that form colonies of adherent myoepithelial and luminal cells in vitro, myoepithelial-restricted progenitors that form colonies of exclusively adherent myoepithelial cells in vitro, and mature myoepithelial cells that are not clonogenic (collectively referred to as basal cells, BCs). The CD49fposEPCAMpos cells are selectively enriched in luminal progenitors (referred to as luminal progenitors, LPs); and the CD49fnegEPCAMpos cells are selectively enriched in mature luminal cells (referred to as luminal cells, LCs). Differences in gene expression in general and telomere associated genes in particular were elucidated by analyzing mammary epithelial subpopulations. Total RNA was isolated from 24 samples obtained from FACS purification of mammary epithelial subpopulations from 9 reduction mammoplasty breast tissues. Global gene expression profiling was performed by array.

Comparative analysis of gene expression of radioresistant prostate cancer cells and prostate cancer progenitors

Project description:By employing a global gene expression profiling, we performed analysis of the molecular pathways which are deregulated in DU145 ALDH+ prostate cancer progenitors and DU145-RR radioresistant cells. Non-sorted, ALDH-negative, and ALDH-positive populations were analyzed, both for parental DU145 cell line and for its radioresistant sub-line. Three independent experiments were performed

Global Expression of Molecular Transporters in the Human Vaginal Tract

Project description:Pre-exposure chemoprophylaxis using antiretroviral agents is a promising strategy for the prevention of sexual HIV transmission in women. Molecular transporters in the human vaginal tract may play a pivotal role in determining drug disposition and, consequently, pharmacodynamic outcomes in these efforts. Little is known, however, on the expression of these transporters in vaginal tissues, representing a critical knowledge gap. Our study analyzed the genome-wide transcriptome in 44 vaginal tissue samples from 6 reproductive-age women undergoing gynecologic surgeries. The genome-wide transcriptome in 44 vaginal tissue samples from 6 reproductive-age women (20-56 years old) undergoing gynecologic surgeries was measured.

Genetically engineering self-organization of human pluripotent stem cells into a liver bud-like tissue using Gata6

Project description:Human induced pluripotent stem cells (hiPSCs) have potential for personalized and regenerative medicine. While most methods of utilizing these cells have focused on deriving homogenous populations of specialized cells, there has been modest success in producing hiPSC-derived organotypic tissues or organoids. Here we present a novel approach for generating and then co-differentiating hiPSC-derived progenitors. With a genetically engineered pulse of GATA6 expression, we initiate rapid emergence of all three germ layers as a complex function of GATA6 expression levels and tissue context. Within two weeks we obtain a complex tissue that recapitulates early developmental processes and exhibits a liver bud-like phenotype, including haematopoietic and stromal cells, as well as a neuronal niche. Our approach addresses two major issues in derivation of tissues from hiPSCs: using a single autologous hiPSCs as source and generating a range of stromal cells that co-develop with parenchymal cells to form complex tissues. Gene expression profiling (microarray) of iPS cells (PGP1) at X days post- doxycycline induction of mouse Gata6. Either total cells or immunomagnetic isolation of cells with specific surface markers. Three samples per group.

Cardiogenic genes expressed in cardiac fibroblasts contribute to heart development and repair

Project description:Cardiac fibroblasts are critical to proper heart function through multiple interactions with the myocardial compartment. Loosely defined based on their mesenchymal origin, capacity to adhere to plastic and to secrete extracellular matrix, cardiac fibroblasts have been largely neglected due to heterogeneity and lack of proper markers. Objective: To identify genes uniquely expressed in the cardiac fibroblast pool, we performed an unbiased comparative analysis between cardiac and tail fibroblasts, and tracked cardiac fibroblasts after injury to determine their contribution to myocardial regeneration. Methods and Results: High-throughput cell surface and intracellular profiling identified homogeneously expressed MSC markers in cardiac fibroblasts, as well as a surprising number of cardiogenic markers, some expressed at higher levels than in cardiomyocytes. Genetically marked fibroblasts contributed to interstitial but not cardiomyocyte compartments in infarcted hearts. Conclusions: The core transcriptional identity of cardiac fibroblasts reflects their embryological origin, provoking novel interpretations for studies on more specialized cardiac progenitors, and offering a novel perspective for reinterpreting cardiac regenerative therapies 3 biological replicates plated over 5 days after isolation pooled out of 2 animals were used for both tail and heart fibroblasts (6 total samples analysed)

Reproduction of reset cell

Project description:Functional-assay limitations are an emerging issue in characterizing human pluripotent stem cells (hPSCs). With rodent PSCs, chimera formation, using pre-implantation embryos, is the gold-standard assay of pluripotency. In hPSCs, this can only be monitored via teratoma formation or in vitro differentiation, as ethical concerns preclude generation of human-animal chimera. To circumvent this issue, we established a functional assay utilizing interspecific blastocyst injection and in vitro culture (interspecies in vitro chimera assay). The assay uses mouse pre-implantation embryos and human PSCs to make interspecies chimeras cultured in vitro to the early egg cylinder stage. When hiPSCs, both conventional and naive type, which called M-bM-^@M-^\reset cellM-bM-^@M-^], were injected into mouse embryos and cultured. The cells were never integrated into the epiblast of egg cylinder stage-embryo. These results suggest that hPSCs, including naM-CM-/ve type, are unable to form chimera with mouse embryo. Reset cells were converted from conventional human iPSC line PB004, and then compared their gene expression profile with or without transgene overexpression induced by doxycyclin treatment.
