blister/プロリン

Benzo(a)pyrene (BP) metabolism has been studied in epidermal blisters maintained in a culture medium for 24 h and 48 h. The viability of the cells has been assayed by [3H]proline incorporation into proteins and by [14C]BP metabolism into unconjugated metabolites. A screen of BP metabolism in 19

We investigated the substrates for flight in the blister beetle Decapotoma lunata by (a) establishing the patterns of maximum activities of enzymes of various metabolic pathways in the flight muscles, (b) measuring the respiratory rates of flight muscle mitochondria with various substrates and (c)

We have investigated potential mechanisms for blister formation by assaying proteolytic enzymes in the blister fluids of patients with various bullous diseases. Blister fluids were obtained from patients with dermatitis herpetiformis (DH), bullous pemphigoid (BP), chronic bullous disease of

Previous work demonstrated that lysine homopeptides adopt a polyproline II (PPII) structure. Lysine homopeptides with odd number of residues, especially with 11 residues (K11), were capable of inhibiting the growth of a broader spectrum of bacteria than those with an even number. Confocal studies

Porphyrias are rare metabolic hereditary diseases originating from defects in specific enzymes involved in the heme biosynthesis pathway. Congenital erythropoietic porphyria (CEP) is the rarest autosomal recessive porphyria resulting from a deficiency of uroporphyrinogen III cosynthase (UROS), the

Sulfur and nitrogen mustards are internationally banned vesicants listed as Schedule 1 chemical agents in the Chemical Weapons Convention. These compounds are highly reactive electrophiles that form stable adducts to a variety of available amino acid residues on proteins upon exposure. We present a

Mutations in the genes encoding the subunit polypeptides of the alpha6beta4 integrin (ITGA6 and ITGB4, respectively) have been previously demonstrated in patients with a lethal form of epidermolysis bullosa with congenital pyloric atresia (OMIM #226730). In this study, we demonstrate for the first

The clinical features of the Dowling-Meara variant of epidermolysis bullosa simplex (EBS-DM) can, in an infant, be indistinguishable from other severe forms of epidermolysis bullosa (EB). Two unrelated infants with no family history of skin disease are described who, within hours of birth, developed

Hailey-Hailey disease (HHD) is an autosomal dominant skin disorder characterized by recurrent eruption of vesicles and bullae at the sites of friction and in the intertriginous areas. Mutations in the ATP2C1 gene encoding the human secretory pathway calcium ATPase 1 (hSPCA1) have been identified as

Sulfur mustard (SM) is a chemical warfare agent that causes painful blisters and chemically modifies endogenous biomacromolecules by alkylation to hydroxyethylthioethyl (HETE) adducts representing valuable long-term markers for post-exposure analysis. The albumin adduct formed in human plasma in

Epidermolysis bullosa simplex (EBS), an inherited genetic disorder, is most often caused by a dominant-negative mutation in either the keratin 5 (KRT5) or the keratin 14 (KRT14) gene. These keratin mutants result in a weakened cytoskeleton and cause extensive cytolysis. It is important to analyze

Autosomal recessive cutis laxa (ARCL) describes a group of syndromal disorders that are often associated with a progeroid appearance, lax and wrinkled skin, osteopenia and mental retardation. Homozygosity mapping in several kindreds with ARCL identified a candidate region on chromosome 17q25. By

A novel microtubule-associated protein (MAP) of M(r) 115,000 has been identified by screening of a HeLa cell cDNA expression library with an anti-serum raised against microtubule-binding proteins from HeLa cells. Monoclonal and affinity-purified polyclonal antibodies were generated for the further

Epidermolysis bullosa simplex (EBS) is characterized by skin blistering due to basal keratinocyte fragility. In one family studied, inheritance of EBS is linked to the gene encoding keratin 14, and a thymine to cytosine mutation in exon 6 of keratin 14 has introduced a proline in the middle of an
