UNLABELLED Transforming growth factor-beta (TGF-β) is an important regulatory suppressor factor in hepatocytes. However, liver tumor cells develop mechanisms to overcome its suppressor effects and respond to this cytokine by inducing other processes, such as the epithelial-mesenchymal transition (EMT), which contributes to tumor progression and(More)
The NADPH oxidase NOX4 has emerged as an important source of reactive oxygen species in signal transduction, playing roles in physiological and pathological processes. NOX4 mediates transforming growth factor-β-induced intracellular signals that provoke liver fibrosis, and preclinical assays have suggested NOX4 inhibitors as useful tools to ameliorate this(More)
A retrospective study was performed analyzing 521 consecutive patients who had either lower eyelid, malar region, or cheek reconstruction performed from January 1960 through December 1985. Of the group, 285 patients had basal cell carcinoma (BCC) of the cheek and malar regions, and 236 had BCC of the lower eyelid. In this paper we reevaluate and illustrate(More)
Hepatocellular carcinoma (HCC) is a heterogeneous tumour associated with poor prognostic outcome. Caveolin-1 (CAV1), a membrane protein involved in the formation of caveolae, is frequently overexpressed in HCC. Transforming growth factor-beta (TGF-β) is a pleiotropic cytokine having a dual role in hepatocarcinogenesis: inducer of apoptosis at early phases,(More)
UNLABELLED Different data support a role for the epidermal growth factor receptor (EGFR) pathway during liver regeneration and hepatocarcinogenesis. However, important issues, such as the precise mechanisms mediating its actions and the unique versus redundant functions, have not been fully defined. Here, we present a novel transgenic mouse model expressing(More)
OBJECTIVE Marfan's syndrome is characterized by the formation of ascending aortic aneurysms resulting from altered assembly of extracellular matrix microfibrils and chronic tissue growth factor (TGF)-β signaling. TGF-β is a potent regulator of the vascular smooth muscle cell (VSMC) phenotype. We hypothesized that as a result of the chronic TGF-β signaling,(More)
