The efficacy of conjugated linoleic acid (CLA) in diet supplements for milk fat reduction is well documented in several species. However, the mechanisms by which fatty acids regulate mammary lipogenesis remain largely unknown, especially with regard to gene expression of enzyme and regulators. In this study, 8 Holstein dairy cows in their mid-lactation period were randomly divided into 2 ... more
To elucidate how physiological and biochemical mechanisms of chilling stress are regulated by abscisic acid (ABA) pretreatment, pepper variety (cv. ‘P70’) seedlings were pretreated with 0.57 mM ABA for 72 h and then subjected to chilling stress at 10°/6°C (day/night). Chilling stress caused severe necrotic lesions on the leaves and increased malondialdehyde and H2O2 ... more
Phosphatidylinositol phosphate kinases (PIPKs) are enzymes that participate in diverse intracellular signaling pathways. They are classified into 3 functionally distinct subfamilies - PIPKI (a, b, g), PIPKII (a, b, g), and PIPKIII - located in various subcellular compartments. Recently, the PIPKIIa and b-globin genes were found to be overexpressed in reticulocytes from 2 siblings with ... more
The precise causes of psoriasis, a chronic skin disorder characterized by hyperproliferation of keratinocytes and incomplete keratinization, are unclear. It is known that expression of helix-loop-helix transcription factor Id1, which functions as an inhibitor of differentiation, is upregulated in psoriatic skin. We investigated the effect of the antipsoriatic drug dithranol on mRNA and ... more
Coffee quality is directly related to the harvest and post harvest conditions. Non-uniform maturation of coffee fruits, combined with inadequate harvest, negatively affects the final quality of the product. Pectin methylesterase (PME) plays an important role in fruit softening due to the hydrolysis of methylester groups in cell wall pectins. In order to characterize the changes occurring ... more
The full-length complementary DNA (cDNA) of heat shock protein 90 was cloned from Phascolosoma esculenta (PeHSP90) using expressed sequence tag and rapid amplification of cDNA end approaches. The cDNA of PeHSP90 was 2521 bp including a 5'-untranslated region of 110 bp, a 3'-untranslated region of 230 bp, and an open reading frame of 2181 bp. All of the characteristic motifs of ... more
Heat shock protein (HSP) 104 is a highly conserved molecular chaperone that catalyzes protein unfolding, disaggregation and degradation under stress conditions. We characterized HSP104 gene structure and expression in Trypanosoma cruzi, a protozoan parasite that causes Chagas’ disease. The T. cruzi HSP104 is an 869 amino-acid protein encoded by a single-copy ... more
The CD44 family belongs to a larger group of hyaluronic acid-binding proteins and plays important roles in oocyte maturation, fertilization and preimplantational embryo development. We analyzed the CD44 receptor in sheep oocytes and embryos. Immature oocytes (N = 66) were obtained from a local abattoir; mature oocytes (N = 35) and embryos (N = 41) were obtained by laparotomy from adult ... more
Boron is an important micronutrient in plants and animals. The role of boron in living systems includes coordinated regulation of gene expression, growth and proliferation of higher plants and animals. There are several well-defined genes associated with boron transportation and tolerance in plants and these genes show close homology with human anion exchanger genes. Mutation of these ... more
Cerebral ischemia or ischemic stroke is mainly attributed to vascular and circulation disorders. Among protein biomarkers, RNA profiles have also been identified as markers of ischemic stroke. MicroRNA-145 expression is ostensibly recognized as marker and modulator of vascular smooth muscle cell phenotype; however, expression levels in ischemic stroke had not been investigated. Employing ... more
