altered expression of cardiac ankyrin repeat protein and its homologue, ankyrin repeat protein with pest and proline-rich region, in atrophic muscles in amyotrophic lateral sclerosis.cardiac ankyrin repeat protein, carp, is a protein that is restrictedly expressed in the heart but barely expressed in skeletal muscles. since carp is induced by pressure overload to the heart, it is proposed to be a genetic marker for cardiac hypertrophy. we recently identified a novel protein, ankyrin repeat protein with pest and proline-rich region (arpp), which is homologous to carp and is preferentially expressed in type 1 skeletal muscle fibers (cf. slow fibers). we also found that both ar ...200212679596
aquatic hypoxia is an disrupter and impairs fish reproduction.there is increasing concern that certain chemicals in the aquatic environment can disrupt endocrine systems, leading to reproductive impairment and threatening survival of wild populations of invertebrates, fish, bird, reptiles, and wildlife. for the first time, we report that hypoxia is also an endocrine disruptor and poses a significant threat to the reproduction and hence sustainability of fish populations. serum levels of testosterone, estradiol, and triiodothyronine significantly decreased ...200312680666
the haemoflagellate trypanoplasma borreli induces the production of nitric oxide, which is associated with modulation of carp (cyprinus carpio l.) leucocyte functions.in an attempt to characterise the role of nitric oxide (no) in immune responses of carp, carp leucocytes obtained during an acute t. borreli infection were examined, for their capacity to generate no. in a second set of experiments the impact no on viability of the parasite and on the modulation of functional carp leucocyte responses were tested in vitro. both in carp head-kidneys and in the peripheral blood, the fractions of lymphoblasts among separated leucocytes were increased. however, the r ...200312681277
local expression of apolipoprotein a-i gene and a possible role for hdl in primary defence in the carp skin.antimicrobial proteins and peptides play an important role in the primary defence of epithelial barriers in vertebrates and invertebrates. here we report the detection of the apolipoproteins a-i and a-ii in the epidermis and epidermal mucus of the carp (cyprinus carpio l.) by immunohistochemistry and western blot analysis. both apolipoproteins are major constituents of high density lipoprotein and have been shown to display antiviral and antimicrobial activity in mammals. therefore the aim of th ...200312681280
