Methylated DNA binding protein 2 (MBD2) binds methylated promoters and suppresses transcription in cis through recruitment of a chromatin modification repressor complex. We show here a new mechanism of action for MBD2: suppression of gene expression indirectly through activation of microRNA hsa-mir-496. Overexpression of MBD2 in breast epithelial cell line MCF-10A results in induced expression ...
Idiopathic pulmonary fibrosis (IPF) is thought to involve inflammatory cells and reactive oxygen species (ROS), such as superoxide anion radical (O2(·-)). There is currently no effective treatment of IPF. We previously developed a human serum albumin (HSA)-thioredoxin 1 (Trx) fusion protein (HSA-Trx) designed to overcome the unfavorable pharmacokinetic and short pharmacological properties of Tr...
Hsa is a large, serine-rich protein of Streptococcus gordonii DL1 that mediates binding to α2-3-linked sialic acid termini of glycoproteins, including platelet glycoprotein Ibα, and erythrocyte membrane protein glycophorin A, and band 3. The binding of Hsa to platelet glycoprotein Ibα contributes to the pathogenesis of infective endocarditis. This interaction appears to be mediated by a second ...
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...
We have investigated the potentiation of transferrin [Tfn]-toxin [Tfn-ricin 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 ...

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...
