TGF-β signalling has key functions in cell growth, differentiation, apoptosis, development and tumorigenesis. The mechanisms that lead to receptor activation and gene expression responses to TGF-β are generally understood 1. Binding of TGF-β to a complex of two type I and two type II kinase receptors, namely TβRI and TβRII, confers TβRI activation and(More)
Tamoxifen can stimulate the growth of some breast tumors and others can become resistant to tamoxifen. We previously showed that unliganded ERbeta inhibits ERalpha-mediated proliferation of MCF-7 cells. We investigated if tamoxifen might have a potential negative effect on some breast cancer cells by blocking the effects of unliganded ERbeta on gene(More)
TGF-b is produced excessively by many solid tumors and can drive malignant progression through multiple effects on the tumor cell and microenvironment. TGF-b signaling pathway inhibitors have shown efficacy in preclinical models of metastatic cancer. Here, we investigated the effect of systemic LY2109761, a TGF-b type I/II receptor (TbRI/TbRII) kinase(More)
TGF beta can promote and/or suppress prostate tumor growth through multiple and opposing actions. Alterations of its expression, secretion, regulation or of the sensitivity of target cells can lead to a favorable environment for tumor development. To gain a better insight in TGF beta function during cancer progression, we have used different cultured human(More)
PURPOSE Nonmelanoma skin cancer incidence is enhanced >50-fold in patients taking antirejection drugs (ARD) following organ transplantation. Preclinical studies suggest that ARD treatment increases transforming growth factor-beta1 (TGF-beta1) levels, which contribute to enhanced tumor susceptibility independent of the immunosuppressive effects of ARDs.

Long-term estrogen deficiency increases the risk of obesity, diabetes and metabolic syndrome in postmenopausal women. Menopausal hormone therapy containing estrogens might prevent these conditions, but its prolonged use increases the risk of breast cancer, as wells as endometrial cancer if used without progestins. Animal studies indicate that beneficial(More)
Cancer cells display alterations in many cellular processes. One core hallmark of cancer is the Warburg effect which is a glycolytic reprogramming that allows cells to survive and proliferate. Although the contributions of environmental contaminants to cancer development are widely accepted, the underlying mechanisms have to be clarified. Benzo[a]pyrene(More)
Mice with the hypomorphic AIF-Harlequin mutation exhibit a highly heterogeneous mitochondriopathy that mostly affects respiratory chain complex I, causing a cerebral pathology that resembles that found in patients with AIF loss-of-function mutations. Here we describe that the antidiabetic drug pioglitazone (PIO) can improve the phenotype of a mouse(More)

Preclinical studies suggest that ARD treatment increases transforming growth factor-β1 (TGF-β1) levels, which contribute to enhanced tumor susceptibility independent of the immunosuppressive effects of ARDs.
