The majority of mutations that cause isolated GH deficiency type II (IGHD II) affect splicing of GH-1 transcripts and produce a dominant-negative GH isoform lacking exon 3 resulting in a 17.5-kDa isoform, which further leads to disruption of the GH secretory pathway. A clinical variability in the severity of the IGHD II phenotype depending on the GH-1 gene(More)
OBJECTIVE To determine if abnormal collagen metabolism is correlated with neurogenic inflammation, a potential activator of collagen metabolism, in patients with fibromyalgia (FM). METHODS The presence of inflammatory cytokines, interleukin (IL)-1beta, IL-6, and tumor necrosis factor (TNF)-a was investigated in skin tissues by using reverse(More)
Increased longevity of hypopituitary dwarf mice and GH- resistant knockout mice appears to be in contrast with observations made in clinical practice. In humans, on one hand hypopituitarism and GH deficiency (GHD) are believed to constitute risk factors for cardiovascular disease and, therefore, early death. But on the other hand, patients with a PROP-1(More)
Human GH has two disulfide bridges linking Cys-53 to Cys-165 and Cys-182 to Cys-189. Although absence of the first disulfide bridge has been shown to affect the bioactivity of GH in transgenic mice, little is known of the importance of this bridge in mediating the GH/GH-receptor (GHR) interaction in humans. However, we have identified a missense mutation(More)
Four distinct familial types of isolated GH deficiency have been described so far, of which type II is the autosomal dominant inherited form. It is mainly caused by mutations within the first 6 bp of intervening sequence 3. However, other splice site and missense mutations have been reported. Based on in vitro experiments and transgenic animal data, there(More)
OBJECTIVE Growth is an inherent property of life. About 10% of the congenital forms of growth retardation and short stature are genetically caused. Beside the gene involved in direct GH-production, there are different candidate genes important for appropriate pituitary development causing combined pituitary hormone deficiency (CPHD). However, severe growth(More)
BACKGROUND Mast cells activation through FcepsilonRI cross-linking has a pivotal role in the initiation of allergic reactions. The influence of this activation on programmed cell death of human mast cells has not yet been clarified. This study evaluates the influence of IgE-dependent activation alone and in synergy with TRAIL on the expression of molecules(More)
OBJECTIVE Four distinct familial types of isolated GH deficiency (IGHD) are classified, of which type II, IGHD II, is the autosomal dominant inherited form. Based on clinical data, it became evident that there is a wide variability in phenotype among the various GH-1 gene alterations leading to the disorder. As subjects suffering from IGHD II caused by the(More)
