Fibro-osseous lesions of the maxillofacial complex are often difficult to diagnose from both a clinical and a histopathologic point of view. The parameters for the diagnosis of juvenile active ossifying fibroma are as follows: a patient under 15 years of age, localization of the tumor, the radiologic aspect, and the tendency to recur. Although many authors(More)
Met tyrosine kinase receptor, also known as c-Met, is the HGF (hepatocyte growth factor) receptor. The HGF/Met pathway has a prominent role in cardiovascular remodelling after tissue injury. The present review provides a synopsis of the cellular and molecular mechanisms underlying the effects of HGF/Met in the heart and blood vessels. In vivo, HGF/Met(More)
Omphalocele is the most common congenital defect of the abdominal wall. Mortality rate is between 20 and 70% and early closure of the abdominal wall, within 10 days of life, is vital to the successful outcome of the surgical treatment. The authors describe the use of two bipedicled flaps of abdominal skin to correct the defect of the midline as soon as the(More)
In order to study the effects of Hepatocyte Growth Factor (HGF) in the heart, two transgenic mice were developed, one carrying a bidirectional HGF-TetO-GFP responder construct and the other carrying a α-MHC-tTA transactivator construct. Crosses were carried out between heterozygotes, so that litters contained bitransgenic α-MHC-tTA/HGF-TetO-GFP+, thus(More)
Cardiac hypertrophy is the heart's response to a variety of extrinsic and intrinsic stimuli, some of which might finally lead up to a maladaptive state. An integral part of the pathogenesis of the hypertrophic cardiomyopathy disease (HCM) is the activation of the rat sarcoma (RAS)/RAF/MEK (mitogen-activated protein kinase kinase)/MAPK (mitogen-activated(More)
Hepatocyte Growth Factor (HGF) controls growth and differentiation in different cell types, including cardiac cells. However, its downstream effectors are poorly understood. To investigate the transcriptional targets of HGF, we analyzed the hearts of neonatal mice with cardiomyocyte-specific HGF overexpression with whole genome DNA microarrays. When(More)
Hepatocyte growth factor (HGF) and its tyrosine kinase receptor (Met) play important roles in myocardial function both in physiological and pathological situations. In the developing heart, HGF influences cardiomyocyte proliferation and differentiation. In the adult, HGF/Met signaling controls heart homeostasis and prevents oxidative stress in normal(More)
Among other diseases characterized by the onset of cachexia, congestive heart failure takes a place of relevance, considering the high prevalence of this pathology in most European countries and in the United States, and is undergoing a rapid increase in developing countries. Actually, only few models of cardiac cachexia exist. Difficulties in the(More)
Activation of the hepatocyte growth factor/Met receptor is involved in muscle regeneration, through promotion of proliferation and inhibition of differentiation in myogenic stem cells (MSCs). We previously described that the specific expression of an oncogenic version of the Met receptor (Tpr-Met) in terminally-differentiated skeletal muscle causes muscle(More)
Ischaemic heart disease is the main cause of death in western countries. Cardiac tissue is primarily damaged by cardiomyocyte cell death triggered by low oxygen supply to the heart (hypoxia). The current therapeutic approach is coronary angioplastic intervention or thrombolytic treatments to resume blood flow in the ischaemic heart. Unfortunately,(More)
