Disruption of E-cadherin (CDH1 gene) expression, subcellular localization or function arises during initiation and progression of almost 90% of all epithelial carcinomas. Nevertheless, the mechanisms through which this occurs are largely unknown. Previous studies showed the importance of CDH1 intron 2 sequences for proper gene and protein expression,(More)
C-fos is an immediate-early gene whose expression in the spinal cord has been extensively used as a marker of peripheral noxious stimulation. The Fos protein accumulates in the nuclei of spinal neurons, reaching detectable levels 2 h after stimulation. The ERK pathway is an important signalling pathway in spinal cord neurons. ERK is activated upon(More)
The objective of this study was to assess the quality of the contents related to screening in a sample of websites providing information on breast and prostate cancer in the Portuguese language. The first 200 results of each cancer-specific Google search were considered. The accuracy of the screening contents was defined in accordance with the state of the(More)
C a firm that would like to commit to a focused business strategy because focus improves efficiency and thus increases profit. We identify two general conditions under which tougher competition strengthens the firm’s ability to commit to a focused strategy. Under these conditions, competition fosters commitment for two reasons: (i) competition reduces the(More)
Hereditary diffuse gastric cancer (HDGC) syndrome, although rare, is highly penetrant at an early age, and is severe and incurable because of ineffective screening tools and therapy. Approximately 45% of HDGC families carry germline CDH1/E-cadherin alterations, 20% of which are nonsense leading to premature protein truncation. Prophylactic gastrectomy is(More)
