Cell-to-cell heterogeneity of EWSR1-FLI1 activity determines proliferation/migration choices in Ewing sarcoma cells.

Ewing sarcoma is characterized by the expression of the chimeric EWSR1-FLI1 transcription factor. Proteomic analyses indicate that the decrease of EWSR1-FLI1 expression leads to major changes in effectors of the dynamics of the actin cytoskeleton and the adhesion processes with a shift from cell-to-cell to cell-matrix adhesion. These changes are associated with a dramatic increase of in vivo cell migration and invasion potential.

The p53 Target Gene SIVA Enables Non-Small Cell Lung Cancer Development.

Unlabelled: Although p53 transcriptional activation potential is critical for its ability to suppress cancer, the specific target genes involved in tumor suppression remain unclear. SIVA is a p53 target gene essential for p53-dependent apoptosis, although it can also promote proliferation through inhibition of p53 in some settings. Thus, the role of SIVA in tumorigenesis remains unclear.

[Cardiovascular risk factors in France. Prevalence and association].

The object of this study was to assess the prevalence of modifiable cardiovascular risk factors and their association in 61,108 subjects over 15 years of age who volunteered for a systematic medical check-up, free of charge, and performed in a health centre in central France. The risk factors were defined as follows: hypertension, diabetes, hypercholesterolaemia, hypertriglyceridaemia: medical treatment or value above the upper limits of normal defined by national or international recommendations. obesity and android fat distribution as defined by the principal recommendations.

High blood pressure and associated cardiovascular risk factors in France.

Objective: To estimate, with respect to age and gender, the prevalence of high blood pressure (BP) in treated and non-treated subjects and its association with other cardiovascular risk factors.

Design: A cross-sectional study.

Setting: Healthcare centres in the centre of France.

Reference values for clinic pulse pressure in a nonselected population.

A wide pulse pressure (PP) may constitute an independent predictor of cardiovascular morbidity and mortality. We assessed the reference values of brachial clinic PP, according to age and gender in a nonselected population (61,724 subjects) who were undergoing a routine systematic health examination. According to mean values, 50 mm Hg is likely the reference value for clinic PP in both men and women.
