Project description:Malignant melanoma is a complex genetic disease and the most aggressive form of skin cancer. Melanoma progression and metastatic dissemination fundamentally relies on the process of angiogenesis. Melanomas produce an array of angiogenic modulators that mediate pathological angiogenesis. Such tumor-associated modulators arbitrate the enhanced proliferative, survival and migratory responses exhibited by endothelial cells, in the hypoxic tumor environment. The current study focuses on melanoma-induced survival of endothelial cells under hypoxic conditions. Melanoma conditioned media were capable of enabling prolonged endothelial cell survival under hypoxia, in contrast with the conditioned media derived from melanocytes, breast and pancreatic tumors. To identify the global changes in gene expression and further characterize the pro-survival pathway induced in endothelial cells, we performed microarray analysis on endothelial cells treated with melanoma conditioned medium under normoxic and hypoxic conditions.

Huvec cells were grown in melanoma conditioned medium or DMEM 10% FCS for 12 h under hypoxic or normoxic conditions. In order to identify the transcripts modulated by melanoma CM, samples treated with MCM were compared to those grown in DMEM alone.

Project description:The signaling events triggered by soluble mediators released from both transformed and stromal cells shape the phenotype of tumoral cells and have significant implications in cancer development and progression. In this study we performed an in vitro heterotypic signaling assay by evaluating the proteome diversity of human dermal fibroblasts after stimulation with the conditioned media obtained from malignant melanoma cells. In addition, we also evaluated the changes in the proteome of melanoma cells after stimulation with their own conditioned media as well as with the conditioned medium from melanoma-stimulated fibroblasts. Our results pointed out to a significant rearrangement in the proteome of stromal and malignant cells upon crosstalk of soluble mediators. The main proteome signature of stimulated cells was related to protein synthesis, which may indicate that this process might be an early response of stimulated stromal cells. In addition, the conditioned medium derived from ‘primed’ stromal cells (melanoma-stimulated fibroblasts) was more effective in altering the functional phenotype (cell migration) of malignant cells than the fibroblast conditioned medium alone. Collectively, self- and cross-stimulation may play a key role in shaping the tumor microenvironment and, more importantly, enable tumoral cells to succeed in the process of melanoma progression and metastasis. Although the proteome landscape of cells participating in such a heterotypic signaling represents a snapshot of a highly dynamic state, understanding the diversity of proteins and enriched biological pathways resulting from stimulated cell states may allow for targeting specific cell regulatory motifs involved in melanoma progression and metastasis.

Project description:Identification of factors in conditioned media of first-trimester placental villous explants. Explants were cultured under hypoxia (2% O2), 5% CO2 in serum-free DMEM/F12 and treated with recombinant galectin-7 (1ug/ml) or vehicle control (BSA) for 72h. Identification of factors in conditioned media of first-trimester placental villous explants. Explants were cultured under superoxia (20% O2), 5% CO2 in serum-free DMEM/F12 and treated with recombinant galectin-7 (1ug/ml) or vehicle control (BSA) for 72h.

Project description:Kaposi sarcoma is the most common cancer in AIDS patients and is typified by red skin lesions. The disease is caused by the KSHV virus (HHV8) and is recognizable by its distinctive red skin lesions. The lesions are KSHV infected spindle cells, most commonly the lymphatic endothelial and blood vessel endothelial cells (LEC and BEC), plus surrounding stroma. Here we examine KSHVs modulation of Notch signaling using wild-type LEC cells co-cultured with DLL4 and JAG1 expressing LEC cells. Experiment Overall Design: There are 1) n=2 of LEC control cells co-cultured with pSIN expressing LEC, 2) n=3 of LEC co-cultured with pSIN-Dll4 expressing LEC, and 3) n=3 of LEC co-cultured with pSIN-JAG1 expressing LEC.
