Vascular endothelial cells adapt to changes in blood flow by altering the cell architecture and by producing various substances. We have previously reported that low shear stress induces endothelin 1 (ET-1) expression in endothelial cells and that this induction is mediated by depolymerization of actin fiber. In the present study, we examined the role of Ca2+ and protein kinase C (PKC) in shear...

actins are small globular filaments functioning in cell processes like muscle contraction, and stabilized to the sarcomeric z- discs by actin binding proteins (actinins). one of the important gene coding for actin binding proteins in fast twitch fibers is alpha- actinin- 3 (actn3). in this research, we have conducted a gene profile study investigating the genotype and allele distributions of ac...

The evolution of actin gene families is characterized by independent expansions and contractions across the eukaryotic tree of life. Here, we assess diversity of actin gene sequences within three lineages of the genus Arcella, a free-living testate (shelled) amoeba in the Arcellinida. We established four clonal lines of two morphospecies, Arcella hemisphaerica and A. vulgaris, and assessed thei...

Chlamydomonas flagellar inner-arm dynein consists of seven subspecies (a-g), of which all but f contain actin as subunits. The mutant ida5 and a new strain, ida5-t, lack four subspecies (a, c, d, and e). These mutants were found to have mutations in the conventional actin gene, such that its product is totally lost; ida5 has a single-base deletion that results in a stop codon at a position abou...

systemic lupus erythemathosus is an autoimmune disease that affected many various types of tissues in 10% of world population and over 30 genes has associated with it. nouroimmunoendocrynology concepts have shown that immune system could be affected by neuron system and vice versa, 5-hydroxytryptamine receptor a (5ht3ra) was studied as a main receptor in these relations. in this study, peripher...

Multigenic influences are major contributors to human genetic disorders. Since humans are highly polymorphic, there are a high number of possible detrimental, multiallelic gene pairs. The actin cytoskeleton of yeast was used to determine the potential for deleterious bigenic interactions; approximately 4800 complex hemizygote strains were constructed between an actin-null allele and the nonesse...

In order to find the cellular interaction factors of the Heliothis armigera nuclear polyhedrosis virus capsid protein VP39, a Heliothis armigera cell cDNA library was constructed. Then VP39 was used as bait. The host actin gene was isolated from the cDNA library with the yeast two-hybrid system. This demonstrated that VP39 could interact with its host actin in yeast. In order to corroborate thi...

Penyakit antraknosa merupakan salah satu kendala utama dalam budidaya mangga. ini sangat merugikan produksi mangga terutama pada saat lepas panen. Gejala teramati kultivar Golek di gudang simpan petani Kabupaten Indramayu. Penelitian ditujukan untuk mengidentifikasi jenis cendawan fitopatogen penyebab penyakit sebagai langkah awal menyusun pengendalian yang efektif. Morfologi dikarakterisasi se...

Abstract Actin-binding protein Profilin1 is an important regulator of actin cytoskeletal dynamics in cells, and critical for embryonic development higher eukaryotes. The objective the present study was to examine consequence loss-of-function Pfn1 vascular endothelial cells (ECs) vivo. We utilized a mouse model engineered tamoxifen-inducible bi-allelic inactivation gene selectively EC (Pfn1EC-KO...
