Methylglyoxal-bis(cyclopentylamidinohydrazone) (MGBCP) has been synthesized as a multienzyme inhibitor for the polyamine-synthesizing pathway. This drug inhibited S-adenosylmethionine decarboxylase (EC 4.1.1.50), spermine synthase and spermidine synthase activities, competitively with S-adenosylmethionine, spermidine, and putrescine, respectively. MGBCP inhibited the growth of human leukemia Mo...
Antibodies, found in human sera from patients with poststreptococcal glomerulonephritis, against proteoglycans (PG) derived from bovine and human glomeruli were investigated. PG were isolated by 4 M guanidine-HCl extraction of whole glomeruli, followed by DEAE-Sepharose CL-6B ion exchange chromatography. The anionic fractions were further purified by chromatography on Sepharose CL-4B. Biochemic...
Retinal S-antigen (S-ag) was purified by monoclonal antibody (MoAb) immunoaffinity chromatography from soluble protein extracts of bovine and human retina. Purification of S-ag was readily achieved by affinity chromatography using four different MoAb-Sepharose 4B columns. The four antibody columns gave different recoveries with material of comparable enrichment with greater than 95% purity as j...
Pyroglutamylated RFamide peptide (QRFP), an important regulator of metabolism and energy homeostasis, has orexigenic effects. QRFP acts via a specific receptor, Gpr103. Gpr103 mRNA is expressed in the rat hypothalamic paraventricular nucleus (PVN). In the PVN, corticotropin-releasing factor (CRF), which plays a central role in regulating the stress response and is produced in response to stress...
Background: We examine the GA-repeat core promoters of MECOM and GABRA3 in human embryonic kidney-293 cell line and show that those GA-repeats have promoter activity,and those different alleles of the repeats can significantly alter gene expression.We propose a novel role for GA-repeat core promoters to regulate gene expression in the genes involved in development and evolution. Materials and M...
For various reasons, it seems sensible to redesign or design proteins from the inside out. Past approaches in this field have involved iterations of mutagenesis and characterisation to 'evolve' designs. Increasingly, combinatorial approaches are being taken to select 'fit' sequences from libraries of variant proteins. In particular, in silico methods have been used to good effect. More recently...
It has been proposed that in humans 4b-hydroxycholesterol is formed mainly by CYP3A-catalyzed metabolism of cholesterol and thus may serve as an endogenous marker for CYP3A activity. The cynomolgus monkey is widely used as one of the nonrodent preclinical safety species in pharmaceutical research. In the current study, the potential application of 4b-hydroxycholesterol as an endogenous biomarke...
conclusions these results exhibited the immuno potentiator effects of mip-3beta plasmid when coadministrated with the hcv core dna vaccine. complimentary studies integrating mip-3beta as a genetic adjuvant in hcv-core-dna vaccination models are warranted. results mice covaccinated with mip-3beta elicited an enhanced th1 biased systemic immune response as evidenced by higher ifn-γ/il-4 and anti-...
