TL;DR: Factors commonly associated with and partly dependent on obesity, insulin resistance, such as overactivity of the sympathetic, stimulation of the renin–angiotensin–aldosterone systems, abnormal renal sodium handling, endothelial dysfunction, and large vessels' alterations, may play a key role in the blood pressure elevation of the syndrome.
Abstract: Arterial hypertension is often part of a constellation of anthropometric and metabolic abnormalities that occur simultaneously to a higher degree than would be expected by chance alone, supporting the existence of a discrete disorder, the so-called metabolic syndrome. It is the result of interactions among a large number of interconnected mechanisms, which eventually lead to both an increase in cardiovascular and renal risk, and the development of diabetes. Mechanisms involved in the metabolic syndrome are obesity, insulin resistance, and a constellation of independent factors, which include molecules of hepatic, vascular, and immunologic origin with pro-inflammatory properties. At each of these key points are interactions of demographics, lifestyle, genetic factors, and environmental fetal programming. Superimposing upon these are infections or chronic exposure or both to certain drugs that can also make their contribution. Skeletal muscle and the liver, not adipose tissue, are the two key insulin-response tissues involved in maintaining glucose balance, although abnormal insulin action in the adipocytes also plays a role in development of the syndrome. Factors commonly associated with and partly dependent on obesity, insulin resistance, such as overactivity of the sympathetic, stimulation of the renin-angiotensin-aldosterone systems, abnormal renal sodium handling, endothelial dysfunction, and large vessels' alterations, may play a key role in the blood pressure elevation of the syndrome.

TL;DR: In this article, a comprehensive screening of the FLNA gene in a group of 23 unrelated probands (11 familial instances, 12 simplex cases; total affected individuals 32) with frontometaphyseal dysplasia is reported.
Abstract: Frontometaphyseal dysplasia is an X-linked trait primarily characterized by a skeletal dysplasia comprising hyperostosis of the skull and modeling anomalies of the tubular bones. Extraskeletal features include tracheobronchial, cardiac, and urological malformations. A proportion of individuals have missense mutations or small deletions in the X-linked gene, FLNA. We report here our experience with comprehensive screening of the FLNA gene in a group of 23 unrelated probands (11 familial instances, 12 simplex cases; total affected individuals 32) with FMD. We found missense mutations leading to substitutions in the actin-binding domain and within filamin repeats 9, 10, 14, 16, 22, and 23 of filamin A in 13/23 (57%) of individuals in this cohort. Some mutations present with a male phenotype that is characterized by a severe skeletal dysplasia, cardiac, and genitourinary malformations that leads to perinatal death. Although no phenotypic feature consistently discriminates between females with FMD who are heterozygous for FLNA mutations and those in whom no FLNA mutation can be identified, there is a difference in the degree of skewing of X-inactivation between these two groups. This observation suggests that locus heterogeneity may exist for this disorder.

TL;DR: Background Cutaneous mastocytosis (CM) is a typical presentation of mastocybosis in children, however, systemic mastocyTosis may also occur in children.
Abstract: Background Cutaneous mastocytosis (CM) is a typical presentation of mastocytosis in children. However, systemic mastocytosis may also occur in children.
Objective We tried to characterize the clinical features of childhood-onset mastocytosis and estimate the value of the SCORMA (SCORing Mastocytosis) Index and serum tryptase levels as disease severity parameters.
Methods In a survey of 101 children mastocytosis was diagnosed and classified according to World Health Organization criteria. In all the cases serum tryptase levels and the SCORMA Index were done to assess the extent and intensity of the disease.
Results Cutaneous mastocytosis was diagnosed in 100 children; 84% of them presented maculopapular CM, 10% mastocytoma and 6% diffuse cutaneous mastocytosis. Moreover, systemic mastocytosis with bone marrow infiltration and associated with maculopapular CM was found in one case. There was a positive correlation of serum tryptase level to the SCORMA Index. Both the mean tryptase level and the mean SCORMA Index were elevated in diffuse cutaneous mastocytosis children when compared with other forms CM. A significantly higher mean tryptase level was found in children with flushing, hypotension, diarrhoea, extensive bullous lesions and osteoporosis or osteopenia.
Conclusion Mastocytosis in children usually has a benign course. Nevertheless, severe mediator-related symptoms and systemic involvement may appear. Therefore, a multidisciplinary approach involving careful monitoring of the serum tryptase level, SCORMA Index and the organ function is recommended. Both tryptase levels and the SCORMA Index are of a great value as disease severity parameters and they should be assessed simultaneously in all mastocytosis patients.

TL;DR: Compound oligomeric matrix protein is a novel biomarker in breast cancer, which contributes to the severity of the disease by metabolic switching and increasing invasiveness and tumor cell viability, leading to reduced survival in animal models and human patients.
Abstract: Cartilage oligomeric matrix protein (COMP) is a soluble pentameric protein expressed in cartilage and involved in collagen organization. Tissue microarrays derived from two cohorts of patients with breast cancer (n=122 and n=498) were immunostained, revealing varying expression of COMP, both in the tumor cells and surrounding stroma. High levels of COMP in tumor cells correlated, independently of other variables, with poor survival and decreased recurrence-free survival. Breast cancer cells, MDA-MB-231, stably expressing COMP were injected into the mammary fat pad of SCID (CB-17/Icr-Prkdcscid/Rj) mice. Tumors expressing COMP were significantly larger and were more prone to metastasize as compared with control, mock-transfected, tumors. In vitro experiments confirmed that COMP-expressing cells had a more invasive phenotype, which could in part be attributed to an upregulation of matrix metalloprotease-9. Furthermore, microarray analyses of gene expression in tumors formed in vivo showed that COMP expression induced higher expression of genes protecting against endoplasmic reticulum stress. This observation was confirmed in vitro as COMP-expressing cells showed better survival as well as a higher rate of protein synthesis when treated with brefeldin A, compared with control cells. Further, COMP-expressing cells appeared to undergo a metabolic switch, that is, a Warburg effect. Thus, in vitro measurement of cell respiration indicated decreased mitochondrial metabolism. In conclusion, COMP is a novel biomarker in breast cancer, which contributes to the severity of the disease by metabolic switching and increasing invasiveness and tumor cell viability, leading to reduced survival in animal models and human patients.
