We have investigated the potentiation of transferrin |Tfn]-toxin |Tfnricin toxin A chain (RTA) and Tfn-So6 saporin toxin) and monoclonal antibody-RTA conjugates by monensin (Mo) and by a human serum albumin (HSA)-monensin conjugate in vitro. The in vivo survival and in vitro and in vivo toxicity of HSA-Mo were also studied; monensin was chemically linked to HSA carrier protein via a disulfide b...

MicroRNAs (miRNAs) are small noncoding RNAs that involved in various cancer-related cellular processes. Diverse studies on expression profiling of miRNAs have been performed and the data showed that some miRNAs are up-regulated or down-regulated in cancer. Until now, there are no data published on the miRNA expression in head and neck cancers from Malaysia. Hence, this study aimed to investigat...

INTRODUCTION MicroRNAs (miRNAs) are small regulatory RNAs that do not code for proteins. Detection of circulating tumor cells (CTC) would provide diagnostic and prognostic information in prostate tumors (PT). Thus, miRNAs could constitute a promising new class of biomarkers for CTC detection. OBJECTIVES To analyze circulating microRNAs in whole blood as non-invasive markers in patients with l...

Rhabdomyolysis-associated acute kidney injury (AKI) is a serious life-threatening condition. As such, more effective strategies are needed for its prevention. Thioredoxin-1 (Trx), a redox-active and macrophage migration inhibitory factor (MIF) modulating protein, has a short retention time in the blood. We examined the renoprotective effect of long acting Trx that was genetically fused with hum...

The binding of some cephalosporins to human serum albumin (HSA) was studied by an ultrafiltration technique. Changes in C-3 side chain resulted in marked changes in the binding to HSA, but changes in C-7 side chain did not. Cephalosporins were classified into three groups by C-3 side chain: (i) Cationic side chain with low affinity for HSA; (ii) anionic side chain with high affinity for HSA; (i...

Currently, there is no characteristic microRNA (miRNA) expression pattern in Epstein-Barr virus+ diffuse large B-cell lymphoma of the elderly (EBV+DLBCLe). This study aims to characterize a signature profile and identify miRNAs that can be used as biomarkers and alternative therapeutic targets for EBV+DLBCLe. Seventy-one DLBCL patients aged 50 years and older were included and four EBV+ and fou...

BACKGROUND AND PURPOSE Studies using animal models of stroke have shown that human serum albumin (HSA) significantly ameliorates cerebral ischemic injury after both transient and permanent ischemia, even when administered after the onset of ischemia or reperfusion. The mechanism of this effect remains uncertain, and prior studies suggest both indirect hemodynamic and direct cytoprotective effec...

A major challenge in organophosphate (OP) research has been the identification and utilization of reliable biomarkers for the rapid, sensitive, and efficient detection of OP exposure. Although Tyr 411 OP adducts to human serum albumin (HSA) have been suggested to be one of the most robust biomarkers in the detection of OP exposure, the analysis of HSA-OP adduct detection has been limited to tec...

Physicochemical studies of the human serum albuminCu(II)-L-histidine (HSA-Cu(II)-L-His) ternary complex at pH 7.5 indicate several interesting features. 1. The dissociation constants of the HSA-Cu(II)-L-His ternary complex and the HSA-Cu(I1) binary complex are 1.38 X 1O-22 and 6.61 x lOen, respectively. 2. The absorption spectrum of the ternary complex system has characteristics similar to thos...

An efficient and highly sensitive chemiluminescence (CL) technique is proposed in the current study for detection of low levels of human serum albumin (HSA). Chemiluminescence (CL) produced during interaction between fluoresceinyl cypridina luciferin analog (FCLA)-1O2 can be modified with the presence of HSA. The conventional CL technique uses a quenching effect of HSA for its quantitative meas...
