Human serum albumin (HSA) displays esterase activity reflecting multiple irreversible chemical modifications rather than turnover. Here, kinetics of the pseudo-enzymatic hydrolysis of 4-nitrophenyl acetate (NphOAc) are reported. Under conditions where [HSA]≥ 5×[NphOAc] and [NphOAc]≥ 5×[HSA], the HSA-catalyzed hydrolysis of NphOAc is a first-order process for more than 95% of its course. From th...
Using microarray data, the present study identified differentially expressed microRNAs (miRNAs) and evaluated their regulatory characteristics in high-grade glioma patients, with the aim to further the understanding into the underlying etiology of the condition. Previously, studies have generally implemented regression or variance analysis, which ignores various background biological factors. H...
The use of targeted drug delivery systems is a growing trend in cancer treatment to decrease the adverse effect of anti-cancer drugs. In this study, we sought to conjugate methotrexate-human serum albumin nanoparticles (MTX-HSA NPs) with luteinizing-hormone releasing hormone (LHRH). The LHRH was intended to target LHRH receptors overexpressed on the several types of tumors. The expression of LH...
Multidrug resistance-associated protein 1 (MRP1/ABCC1) is an important membrane transporter that contributes to cellular disposition of many endobiotic and xenobiotic agents, and it can also confer multidrug resistance. This study aimed to investigate the role of human noncoding microRNA-1291 (hsa-miR-1291) in regulation of ABCC1 and drug disposition. Bioinformatics analyses indicated that hsa-...
MicroRNAs (miRNAs) have been shown to be important for the pathogenesis of Crohn's disease (CD). Exclusive enteral nutrition (EEN) is an effective therapy for inducing remission in CD. We aimed to investigate the alteration of miRNAs expression profile in the terminal ileal mucosa of CD patients before and after EEN. Twenty-five patients and ten healthy individuals were included. MiRNAs express...
AIM To synthesize and to study for photodynamic activity a composite photosensitizer consisting of chlorin e6 and human serum albumin nanoparticles (HSA NPs). MATERIALS AND METHODS Starting from sorption-purified HSA, the albumin nanoparticles with a different degree of lysine residues cross-linking (10; 20; 40, and 100%) were obtained by the coacervation method. The HSA NPs were used for syn...
Cordyceps pruinosa (CP) is often used as Traditional Chinese Medicine, but the substance basis of its medicinal properties is unclear. In this study, two compounds were isolated from CP cultures by column chromatography, and identified as cordycepin and N6-(2-hydroxyethyl)-adenosine (HEA) by Nuclear Magnetic Resonance. In order to understand the efficacy of these two substances as potential the...
The interaction of reducing carbohydrates with proteins leads to a cascade of reactions that are known as glycation or Maillard reaction that have important roles in diabetic complications. In this minireview, structural changes of glycated human serum albumin (GHSA) via various sugars in different incubation times, which reported in scientific literature as well as our research, were reported....
The combinatorial fluorescent dapoxyl dye library was prepared by both solution- and solid-phase synthesis, generating 80 unique dapoxyl derivatives. A fluorescence-based screening toward human serum albumin (HSA) found one highly sensitive HSA binder ( A41-S) with over 55-fold intensity change. Displacement assay showed the selective binding of A41-S to the site I of HSA, addressing its potent...
Abstract Study question Could microRNA profiling be a useful tool towards better understanding the pathophysiological mechanisms leading to non-obstructive azoospermia (NOA) due maturation arrest? Summary answer MicroRNA may an efficient method unveiling arrest pathophysiology as microRNAs constitute master posttranscriptional regulators of cell-cycle control during spermatogenesis. What is kno...
