Abstract
Human Serum Albumin (HSA) undergoes Post-Translational-Modifications (PTMs) leading to isoforms affecting its oncotic and non-oncotic properties. HSA is comprised of several isoforms whose abundance may vary with pathologies such as diabetes, kidney and liver diseases. Studying their impact separately may help to understand their sources and potential pathogenicity and further their evaluation as biomarkers. The present study examined semi-synthetic HSA isoforms to investigate independently their structure by means of advanced mass spectrometry techniques (LC-TOF-MS and ICP-MS), influence on the HSA binding/antioxidant activities using a binding capacity test, and potential impact on albumin quantification by a routine immunoturbidimetric assay. Applying different chemical reactions to a commercial HSA solution, we obtained different solutions enriched up to 53 % of native HSA, 78 % of acetylated HSA, 71 % of cysteinylated HSA, 94 % of oxidized HSA, 58 % of nitrosylated HSA and 96 % of glycated HSA, respectively. Moreover, the semi-synthetic isoforms showed differently altered binding capacities for a panel of ligands (Cu, Cd, Au, Ds and L-T4). Furthermore, immunoturbidimetry was found to be insensitive to the presence and abundance of the different isoforms. The fully characterized semi synthetic HSA isoforms obtained should be useful to further investigate their pathogenicity and potential roles as biomarkers.

Effects of amino acids and albumin administration on albumin metabolism in surgically stressed rats: A basic nutritional study. JPEN J Parenter Enteral Nutr 2023; 47:399-407. [PMID: 36597725 DOI: 10.1002/jpen.2472] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/31/2022] [Revised: 11/25/2022] [Accepted: 12/29/2022] [Indexed: 01/05/2023]
Abstract
BACKGROUND Nutrition therapy and administration of albumin preparations are common in postsurgical patients. However, the effects of these interventions on albumin metabolism are unclear. We elucidated the effect of postoperative albumin and/or parenteral nutrition administration on it. METHODS Sprague-Dawley rats underwent surgery involving intestinal rubbing followed by intestinal exposure. Subsequently, they were administered experimental solutions for 48 h, their blood samples were collected at 24 and 48 h, and livers were excised at 48 h. Based on experimental solutions, rats were divided into five groups: non-surgical (Non-surg); glucose and electrolyte solution (GE); amino acid, glucose, and electrolyte solution (AGE); GE + rat serum albumin (Alb) (GE + Alb); and AGE + Alb. Their plasma albumin concentrations; albumin fractional synthesis rate (ALB FSR); mercaptoalbumin/total albumin ratio (MA ratio); and messenger RNA (mRNA) expressions of albumin and hepatocyte nuclear factor-1 (HNF-1) in the liver were measured. RESULTS The GE and AGE groups showed significant decline in albumin concentrations. ALB FSR was significantly enhanced in the AGE group compared with the GE group. The mRNA expression of albumin was similar to ALB FSR in all groups and that of HNF-1 was significantly decreased in the GE + Alb and AGE + Alb groups compared with the Non-surg group. The MA ratio in the AGE group was similar to the Non-surg group. CONCLUSION The administration of amino acids comprising parenteral nutrition after surgery augmented ALB FSR and maintained the MA ratio only without simultaneous albumin administration.

Abstract
Glioblastoma, the most common tumor in the brain, has witnessed very little clinical progress over the last decades. Exploring and discovering new therapeutic strategies for glioblastoma has become a critical problem. Harmine (HM), belonging to the beta-carboline alkaloid, is a natural product and isolated from the seeds of Peganum harmala L., which own notable antitumor activity in vitro. However, the poor water solubility and less selectivity of HM severely limit its clinical use. For enhancing its selective ability to tumor cells, we fabricated a kind of protein nanoparticles (BSA-HM NPs), composed of the modified bovine serum albumin (BSA) and HM. It was substantiated through in vitro and in vivo experiment that BSA-HM NPs could predominantly accumulate in tumor tissues and exhibited remarkably enhanced antitumor efficacy. This study provides a promising strategy to improve the bioavailability and avoid side effects of HM as antitumor agents by choosing BSA as carriers.

Abstract
Serum albumin possesses esterase and pseudo-esterase activities towards a number of endogenous and exogenous substrates, but the mechanism of interaction of various esters and other compounds with albumin is still unclear. In the present study, proton nuclear magnetic resonance (1H NMR) has been applied to the study of true esterase activity of albumin, using the example of bovine serum albumin (BSA) and p-nitrophenyl acetate (NPA). The site of BSA esterase activity was then determined using molecular modelling methods. According to the data obtained, the accumulation of acetate in the presence of BSA in the reaction mixture is much more intense as compared with the spontaneous hydrolysis of NPA, which indicates true esterase activity of albumin towards NPA. Similar results were obtained for p-nitophenyl propionate (NPP) as substrate. The rate of acetate and propionate release confirms the assumption that there is a site of true esterase activity in the albumin molecule, which is different from the site of the pseudo-esterase activity Sudlow II. The results of molecular modelling of BSA and NPA interaction make it possible to postulate that Sudlow site I is the site of true esterase activity of albumin.

Abstract
Cell-free and concentrated ascites reinfusion therapy (CART) is used to treat malignant ascites. However, the qualities of albumin in malignant ascites, such as antioxidative activity, may decrease owing to oxidative stress caused by cancer cells and inflammatory reactions. We investigated the fraction percentages of mercaptalbumin (HMA%, reduced form) and non-mercaptalbumin (HNA%, oxidized form) in malignant ascites from 21 patients who received CART and compared the HMA% in the malignant ascites and human serum albumin (HSA) preparations. HMA% of albumin in malignant ascites (22.5%) was significantly lower than that in HSA preparation (42.2%). To ensure a high HMA%, we added L-cysteine to the paracentesis-treated ascites followed by dialysis 1 h later. As a result, the HMA% of albumin in malignant ascites was increased to 59.1%. Our results suggest that using this method in CART will improve patient's albumin quality.

Abstract
Albumin, a major transporting protein in the blood, is the main target of modification that affects the binding of drugs to Sudlow's site I and II. These modification of serum protein moderates its physiological function, and works as a biomarker of some diseases. The main goal of the paper was to explain the possible alteration of human serum albumin binding properties induced by modifications such as glycation, oxidation and ageing, their origin, methods of evaluation and positive and negative meaning described by significant researchers.

Abstract
AIMS The present study to address one of the mechanisms in preeclampsia, examined whether levels of oxidative stress, human serum albumin, and endothelial function correlate in pregnant women and whether human serum albumin reduces levels of superoxide produced by NADPH oxidase activation in the human vascular smooth muscle cells. MATERIALS AND METHODS Pregnant women with (Preeclampsia group, n = 33) and without preeclampsia (Normal group, n = 37) were recruited to determine levels of reactive oxygen species (serum diacron-reactive oxygen metabolite [d-ROM]), and the flow-mediated dilation (FMD). Human coronary arterial smooth muscle cells or omental arteries were subjected to evaluate isometric force recordings, levels of superoxide, western immunoblotting, and immunohistochemistry. The superoxide scavenging assay was also performed in a cell-free system. KEY FINDINGS Women in the preeclampsia group demonstrated lower FMD and higher serum d-ROM values than those in the normal group. There were the inverse correlations between serum levels of d-ROM and the degree of FMD and between serum levels of albumin and those of d-ROM. D-glucose reduced the levcromakalim-induced dilation of human omental arteries, and it increased levels of superoxide and the recruitment of the NADPH oxidase subunit p47phox in human coronary arterial smooth muscle cells. Human serum albumin (0.05 to 0.5 g/dL) prevented these alterations whereas it exerted no superoxide scavenging effect. SIGNIFICANCE Serum albumin relates to oxidative stress inversely, but to the endothelial function positively, in pregnant women. Human serum albumin appears to reduce oxidative stress via NADPH oxidase inhibition in the human vascular smooth muscle, indicating that the serum level may be a critical determinant of vascular oxidative stress in some human diseases.
