Transcription profiling of mouse Deaf-1-transduced mammary epithelial cells

ABSTRACT: Microarray analysis was used to compare the gene expression profiles of Deaf-1-transduced mouse mammary epithelial cells (MECs) relative to Deaf-1-deficient MECs. Experiment Overall Design: To investigate potential target genes of Deaf-1, primary mammary epithelial cells (MECs) were isolated from a Deaf-1-null mouse and immortalised by transduction with a retrovirus encoding the human papilloma virus (HPV16) E6/E7 proteins. Two clones were selected and transduced with either an empty retrovirus or one encoding Deaf-1. RNA was subsequently isolated from cells at 24 and 48 hours after transduction for Affymetrix analysis. High levels of Deaf-1 expression were demonstrated in cells transduced with the Deaf-1 retrovirus relative to controls following a 48 hour selection in puromycin. This time-point was therefore selected for further analysis. Experiment Overall Design: To compare the gene expression profiles of Deaf-1-transduced MECs relative to Deaf-1-deficient MECs, Affymetrix analysis was performed using the GeneChipÂ® Mouse Expression Set 430 2.0 array which comprises 39,000 transcripts on a single array. Total RNA was harvested from two independent clones (C1 and E1) infected with either control or Deaf-1-expressing retrovirus making 4 samples in total. Clones C1 and E1 were treated as biological replicates in the subsequent analysis.

EZH2 controls mammary differentiation independently of its methyltransferase activity through controlling genomic STAT5 access

Project description:Mammary development is characterized by the proliferation and progressive differentiation of alveolar epithelium during pregnancy, culminating in lactation. These processes are largely controlled by hormones through transcription factors. We now explore the contributions of histone methyltransferases, which establish H3K27me3 marks, in the temporally-regulated differentiation of mammary epithelium. Loss of EZH2, but not EZH1, resulted in precocious mammary differentiation, which was facilitated by STAT5 binding to specific target genes and their activation. Mammary stem cells were not compromised in the absence of EZH2. Genome-wide H3K27me3 patterns remained intact in the absence of EZH2. Mammary-specific loci were devoid of H3K27me3 marks in mammary progenitor and mature cells, suggesting no regulatory role for this repressive mark. Lastly, the combined absence of EZH1 and EZH2 inhibited the formation of alveoli. Taken together, EZH2 controls temporally-restricted differentiation of mammary epithelium through H3K27me3-independent mechanisms. mRNA-seq and ChIP-seq in MMTV-Cre (Control), E1-/- (E1KO), E1+/-;E2f/f;control (E1+/-E2KO) and Ezh2f/f;control (E2KO) mammary gland tissues or MECs (purified mammary epithelial cells). H3K27me3 and STAT5 ChIP-seqs in mammary tissues at p13; H3K4me3 ChIP-seq in MECs (mammary epithelial cells) at p13; RNA-seqs at mature virgin (with/without prolactin injection), p13 and p18 mammary tissues.

Protein profiles following miRNA-23c and -4328 overexpression in prostate cancer cell lines, PC-3 and 22Rv1

Project description:The 22Rv1 and PC-3 cells were transduced with shMIMIC human lentiviral vectors (Horizon Discovery, Cambridge, UK) to stably overexpress miRNA-23c or -4328. The SMARTvector Non-Targeting Control (NTC) was expressed to serve as a negative control. The vectors contained a turbo green fluorescent protein (turboGFP) and a puromycin resistance gene cassette. After transduction, cells were cultured in a medium supplemented with 5 µg/mL puromycin (Takara Bio, Tokyo, Japan) for antibiotic selection. Overexpression was confirmed by monitoring the turboGFP by fluorescence microscopy and by RT-qPCR analysis of miRNA-23c and -4328 levels. Relative protein quantification was performed to compare protein expression in 22Rv1 and PC-3 single cell clones overexpressing miRNA-23c and -4328, compared to corresponding NTC cells. Single cell clones overexpressing either miRNA-23c (n = 3), -4328 (n = 3) or NTC (n = 3) were analyzed in triplicate.

Direct Reprogramming of Fibroblasts into Functional Mammary Epithelial cells by small molecules (bulk miRNA-seq)

Project description:Mammary epithelial cells (MECs), the only cell type which could be capable of secreting milk in mammary gland, can be applied for the generation of transgenic mammary cell/gland bioreactor. However, continuously achieving large amount of high-quality goat MECs by non-invasion method, especially prepuberal MECs, in vitro has been a challenge. Here, we show that a small molecules cocktail enables the in vitro generation of chemically-induced mammary epithelial cells (CiMECs) with milk-secreting properties from goat ear fibroblasts. The properties of CiMECs were highly similar to those of naturally isolated MECs. Notably, the CiMECs lineage reprogramming process may partially imitate the MECs developmental process from embryonic to milk-secreting stages. Interestingly, fibroblasts were firstly reversed back to embryonic ectoderm/surface ectoderm-like state. Our findings constitute a substantial step toward further promoting the application of transgenic mammary bioreactors, moreover, also offer a new strategy for obtaining other cell types by reprogrammed fibroblasts.

hTERT effects in CD8 T Lymphocytes from two healthy donors

Project description:Expression in GFP vs. GFP/hTERT transduced CD8 T Lymphocytes from Healty Donors (HD) 1 and 2 at early and late passages. Using CD8+ T lymphocyte clones over-expressing telomerase we investigated the molecular mechanisms that regulate T cell proliferation. Transduction and subcloning procedures were performed on CD8 + naive T-cell clones isolated from two different healthy individuals aged between 30 to 35 years (HD1 and HD2). T-cell cloneswere transduced to express hTERT/GFP or GFP alone. Keywords: Cell Line Comparison.
