Résumé :

The complex PI3K/mTOR pathway regulates tumor progression via effects on cellular proliferation, apoptosis, autophagy, and motility. New drugs that inhibit the catalytic site of both PI3K and mTOR have shown promise in clinical trials. Here, we report the first use of a novel, dual PI3K/mTOR catalytic site inhibitor (PF-04691502, PF1502) in a xenograft model of breast cancer metastasis to bone. Metastatic MDA-MB-1833 cells showed PI3K/mTOR activation relative to parental MDA-MB-231. Low-dose PF1502 significantly impaired tumor cell motility and invasion in vitro without causing cell cycle arre

Tumor biologist have long appreciated that both cell to cell and cell to extracellular matrix (ECM) interactions are involved in the invasive and metastatic events that are characteristic of malignancy. Cancer cell attachment to and invasion of an ECM has been associated with metastatic potential of cell lines of the Dunning rat prostate model. It was postulated that differences observed in the metastatic potential of four Dunning cell lines may correlate with cell-matrix interactions.

Résumé :

Cancer patient mortality is caused by the ability of tumor cells to invade the extracellular matrix and metastasize. Our lab was the first to identify the role of Abl family of non-receptor tyrosine kinases (c-Abl and Arg) in the progression of solid tumor cancers. In our previous studies, we showed that high c-Abl/Arg activity promotes proliferation, invasion, and metastasis in melanoma and breast cancer cells lines. Here, we demonstrate that our previous findings are clinically relevant by showing increased c-Abl/Arg kinase activity in primary melanoma tumor tissue in comparison to low activ

Most women die of ovarian metastasis rather than the effects of the primary tumor.

In addition to genetic and molecular factors, the unique environment of the peritoneal cavity exposes ovarian cells to biophysical forces, particularly fluid shear stress (FSS). These biomechanical forces, only recently identified as a hallmark of cancer, induce rapid signaling events in attached and aggregated cells, a process termed mechanotransduction.

Breast cancer is a multistep disease controlled by a wide spectrum of genetic and epigenetic changes occurring within a cell as well as environmental influences; and it is the most common malignancy in women worldwide, often fatal because of metastasis dissemination.

To unravel the role of miRNAs during breast cancer progression we investigated miRNA expression in 77 ductal breast carcinoma biopsies and 17 mammoplasties by microarray analysis.

Résumé :

Breast cancer (BC) represents a major clinical hurdle, with metastatic outcome accounting for poor patient prognosis. Phenotypic intra-tumor heterogeneity inversely correlates with prognosis in BC and is considered at the basis of metastatization. Traditionally, BC poly-clonal structure was investigated through the genetic barcoding of cells followed by the tracing of the offspring. However, this analysis did not allow a solid investigation of the transcriptional profile associated to clones throughout tumor progression. In this work, we exploited a recently published library of expressed ba

The RbµE2F transcriptional regulatory pathway plays a critical role in the cell cycle. Rb is inactivated through multiple waves of phosphorylation, mediated mainly by cyclin D and cyclin E associated kinases. Once Rb is inactivated, cells can enter Sµphase. Collectively, three Rb family members and ten E2F proteins coordinate every additional stage of the cell cycle, from quiescence to mitosis. However the RbµE2F pathway is frequently altered in cancer. Aside from cell proliferation, the RbµE2F pathway regulates other essential cellular processes including apoptosis, cell differentiation, angi

Increasingly the role of epigenetic machinery as a bridge between underlying DNA sequence and cellular phenotype is being discovered.

Importantly, the epigenetic mechanisms involved in establishing cell identity unsurprisingly contribute to diseased states, including cancer.

This population is composed by distinct WAT progenitors: adipose-derived stem cells (ASCs) and endothelial progenitor cells (EPCs), displaying complementary role in BC progression in preclinical models.

The survival and proliferation of metastases is a consequence of the pre-metastatic niche (PMN) evolution, an abnormal, tumor growth-favoring microenvironment devoid of cancer cells.

Compared to normal melanocytes, melanoma cells produce a large quantity of EVs, that can be detected in the plasma of melanoma patients. For this reason, a full characterization of secreted vesicles subpopulations and of their cargo is necessary to understand how EVs affec

This study focused on the role of RANKL in prostate cancer EMT progression and metastasis. Activation of RANK, a receptor activator of NF-kB, by its ligand RANKL, in a paracrine manner is responsible for osteoclast differentiation and bone remodeling. RANK activation in cancer cells, however, is thought to be promoted by both autocrine and paracrine mechanisms because RANKL has been shown to be derived from either tumor or its microenvironment, such as osteoblasts, infiltrating inflammatory cells and stromal fibroblasts. In the present study, we demonstrated that autocrine and paracrine RANKL-

Résumé :

The initiation of cancer metastasis usually requires Epithelial-Mesenchymal Transition (EMT), by which tumor cells lose cell-cell interactions and gain the ability of migration and invasion. Previous study demonstrated that p68 RNA helicase, a prototypical member of the DEAD-box RNA helicases, functions as a mediator to promote platelet-derived growth factor (PDGF)-induced EMT through facilitating nuclear translocation of β-catenin in colon cancer cells. In this context, p68 RNA helicase was found to be phosphorylated at the tyrosine 593 residue (referred as phosphor-p68) by c-Abl kinase, and

Résumé :

MicroRNAs (miRNAs) are non-coding small RNAs that regulate gene expression at the post-transcriptional level by interacting with the 3'-untranslated region (3'-UTR) of a target gene. Our previous studies indicate that miR-145 is downregulated in breast and colon cancer; moreover, it functions as a tumor suppressor capable of inhibiting tumor cell growth both in vitro and in vivo. In this study, we show that a putative tumor suppressor, miR-145, is regulated through the phosphoinositide-3 kinase (PI-3K)/Akt and p53 pathways. Importantly, p53 transcriptionally induces the expression of miR-145 b

GnRH analogues are used for the treatment of prostate cancer (PCa) because their ability to suppress the activity of the pituitary-testicular axis, with consequent blockade of testosterone production. However, after an initial responsiveness to hormonal deprivation, PCa progresses and then metastatises. It is known that the system of the plasminogen activator (uPA, uPA inhibitors PAI-1/2 and uPA receptor, uPAR) has been involved in the local degradation of the extracellular matrix and PCa progression and metastases. Studies performed in our laboratory have demonstrated the presence of GnRH rec

Résumé :

Platelets play a crucial role for blood hemostasis, the process that prevents bleeding. In addition, platelets have been demonstrated to promote cancer progression and cancer related complications like metastasis and thrombosis. Platelets can affect cancer related diseases either directly or by interacting with other blood cells or molecules in the circulation of individuals with cancer. The current thesis addresses the role of platelets in tumor progression and tumor-induced systemic effects of cancer, with a special focus on the effects on the vasculature. In the first paper, the role of pla

Résumé :

Hepatocellular carcinoma (HCC) is a common malignancy of the liver that is one of the most frequent causes of cancer-related death in the world. Surgical resection and liver transplantation are the only curative options for HCC, and tumor invasion and metastasis render many patients ineligible for these treatments. Identification of the mechanisms that contribute to invasive and metastatic disease may enlighten therapeutic strategies for those not eligible for surgical treatments. In this dissertation, I describe two sets of experiments to elucidate mechanisms underlying HCC dissemination, inv
