Project description:Analysis of growth factor influence on immortalized human meibomian gland epithelial cells at gene expression level. Growth factors play a critical role in the proliferation and differentiation of sebaceous gland epithelial cells. Given that the meibomian gland is a large sebaceous gland, we hypothesize that growth factors exert analogous effects on human meibomian gland epithelial cells. Results provide important information of the response of human meibomian gland epithelial cells to epidermal growth factor (EGF), bovine pituitary extract (BPE), and both, such as up- or down- regulated genes involved in lipid metabolic process and cell cycle. Human meibomian gland epithelial cells were immortalized in our lab with a retrovirus containing telomerase reverse transcriptase (hTERT). hTERT immortalized cells (3 wells /condition / experiment) were seeded onto 6-well plates at the density of 3.76M-CM-^W104cells /well in SFM basal medium, SFM basal medium with epidermal growth factor (EGF; 5 ng/ml), SFM basal medium with bovine pituitary extract (BPE; 50 M-BM-5g/ml), and SFM basal medium with 5ng/ml EGF plus 50 M-BM-5g/ml BPE (KGM). Total RNA was extracted from cultures in SFM basal medium at day 2, and from cultures in SFM basal medium with BPE, basal medium with EGF, and SFM basal medium with EGF plus BPE at day 7.

Project description:ETS transcription factors have recently emerged as important elements in the pathogenesis of prostate cancer (PCa). ETS gene rearrangements leading to over-expression of ETS factors, like ERG, ETV1 and ETV4, are found in about 50% of prostate tumors. While the oncogenic potential of translocated ETS has been demonstrated in several contexts, the impact of endogenously expressed ETS factors on prostate tumorigenesis has been largely overlooked. Here we show that the epithelial-specific ETS factor ESE3, which is normally expressed in basal prostate epithelial (PrE) cells and frequently down-regulated in prostate tumors, serves as gatekeeper to maintain cell differentiation and its down-regulation leads to the acquisition of mesenchymal, stem cell (SC) and tumorigenic properties. ESE3 exerts this function by regulating critical genes involved in the epithelial to mesenchymal transition (EMT) and cell “stemness” and maintaining the equilibrium between cell differentiation and proliferation. Loss of ESE3 may be an important step in prostate tumorigenesis. Keywords: prostate epithelial cells, prostate cancer, gene expression profiling, ETS genes, EMT, cancer stem cells

Project description:Prostatic basal cells have been implicated in differentiation and proliferation during prostate development and regeneration; however, the contribution of zonal variation and the critical role of basal cells in prostatic disease etiology is not well understood. Using single-cell RNA sequencing of primary prostate epithelial cultures, we elucidated organ-specific, zone-specific, and cluster-specific gene expression differences in basal cells isolated from human prostate and seminal vesicle (SV).

Project description:To conduct comparative transcriptomic analyses on normal or malignant prostate epithelial cells in response to tissue contextual changes, we cultured immortalized prostate epithelial cells or prostate cancer cells as cell monolayers or three-dimensional organoids and profiled their transcriptomes in respective culture contexts. RWPE-1 (immortalized prostate epithelial cells) and LNCaP cells (prostate cancer cells) were seeded on reconstituted basement membrane (rBM)-coated culture plastics or cultured within three-dimensional (3D) rBM gels. Total RNA samples were collected from cell monolayers or 3D cell clusters (formed at day 2) or acini or spheroids (formed at day 6) in the rBM culture, followed by global gene expression profiling.

Project description:The newly identified claudin-low subtype of cancer is believed to represent the most primitive breast malignancies, having arisen from transformation of an early epithelial precursor with inherent stemness properties and metaplastic features. Challenging this hypothesis, we show both in vitro and in vivo that transcription factors inducing epithelial-mesenchymal transition can drive the development of claudin-low tumors from differentiated mammary epithelial cells, by playing a dual role in cell transformation and dedifferentiation. Human mammary epithelial cells (HMEC) were sequentially immortalized by hTert (HMEC-hTert), transduced with Twist1 or Zeb2 or Zeb1 and then with H-RasG12V. The gene expression profiles of the resulting HMEC-hTert-Twist1+Ras, HMEC-hTert-Zeb1+Ras and HMEC-hTert-Zeb2+Ras cell lines were defined. HMEC-hTert-Twist1+Ras and HMEC-hTert-Zeb2+Ras cell lines were additionally cultured in presence of TGFM-CM-^C? and their gene expression profiles were determined. The parental HMEC-hTert, the luminal MCF7 and the basal B MDMB157cell lines were used as controls.

Project description:Subset of adult prostate basal cells and fetal prostate epithelial cells have enhanced tubule-initiating capability in vivo. Features associated with this process may be co-opted in cancer cells We used microarrays to contrast gene expression profiles of fetal and adult tubule-initiating cells compared to basal and luminal epithelial cells that can be isolated from bening prostate tissue specimens.
