(Submitter supplied) Self-sufficiency (autonomy) in growth signaling, the earliest recognized hallmark of cancer, is fuelled by the tumor cell’s ability to ‘secrete-and-sense’ growth factors; this translates into cell survival and proliferation that is self-sustained by auto-/paracrine secretion. Using breast cancer cells that are either endowed or impaired in growth signaling autonomy, here we reveal how autonomy impacts cancer progression. more...

(Submitter supplied) Altered signaling pathways typify breast cancer and serve as direct inputs to steroid hormone receptor sensors. We previously reported that phospho-Ser134-GR (pS134-GR) species are elevated in triple negative breast cancer (TNBC) and cooperate with hypoxia-inducible factors, providing a novel avenue for activation of GR in response to local or cellular stress. We probed GR regulation by factors (cytokines, growth factors) that are rich within the tumor microenvironment (TME). more...

(Submitter supplied) Progression to stage IV disease remains the main cause of breast cancer-related deaths. Increasing knowledge of the hematogenous phase of metastasis is key for exploiting the entire window of opportunity to interfere with early dissemination and to achieve a more effective disease control. On the hypothesis that the distinguishing molecular features of circulating tumor cells (CTCs) reveal useful information on metastasis biology and disease outcome, we compared the transcriptomes of CTCs and solid primary/secondary lesions of the MDA-MB-231 xenograft model and provided evidence that blood-borne dissemination is regulated by numerous genes. more...

(Submitter supplied) Purpose: We aim to identify transcriptomic changes associated with EGFR-mediated epithelial to mesenchymal transition in carcinoma cells of the upper aerodigestive tract Method: Kyse30 and FaDu (ATCC, Manassas, VA, USA) were passaged in DMEM or RPMI, 10% FCS, 1% penicillin/streptomycin, 5% CO2 atmosphere at 37°C. Treatment with EGF (PromoCell PromoKine, Heidelberg, Germany), EpEX-Fc (Pan et al. PMID: 30261040) were conducted under serum-free conditions for 6h and 72h. more...

(Submitter supplied) MicroRNAs are widely expressed in the normal pubertal mammary gland and orchestrate mammary gland development by regulating cell proliferation, differentiation, apoptosis, and metabolism. Although human Growth hormone(hGH) plays fundamental roles in normal mammary gland development and elevated autocrine hGH levels have been documented to contribute to breast cancer, whether hGH should influence the expression pattern and the functional roles of miRNAs in this context remain unknown.This study explores the effects of autocrine hGH on microRNA expression in MCF7 cell.

(Submitter supplied) The enumeration of EpCAM-positive circulating tumor cells (CTCs) has allowed clinicians to estimate the overall metastatic burden in breast cancer patients. However, a thorough understanding of CTCs associated with breast cancer brain metastasis (BCBM) is necessary for early identification and evaluation of treatment response to BCBM. In this study, we report that BCBM CTCs are enriched in a distinct sub-population of cells identifiable by their biomarker expression and mutational content. more...
