AB  - Human transferrin (Tf) is a bilobal 76 kDa iron-binding glycoprotein present in human
serum. Each lobe has the ability to bind one ferric ion (Fe3+) and a single synergistic
bicarbonate anion. The main role of Tf is to transport Fe3+ ions through the circulation to
cells, via interaction with transferrin receptor (TFR) on the cell surface. Previously
described methods for Tf isolation and purification are either very time-consuming or
provide Tf of lower final purity. Here we describe a fast and simple FPLC method for the
isolation and purification of Tf from human serum. Serum samples were prepared by
precipitation, while protein purification was performed on FPLC system, using an anionexchange
column. Several different buffers at the same pH were tested. Tf purified by this
method was analyzed by Western blot, followed by immunodetection, as well as with
silver staining after SDS PAGE. Its functionality was tested with respect to iron-binding
capacity (ferozzine method) and its ability to interact with TFR by immunofluorescent
staining. The conformation of purified Tf was analyzed by recording intrinsic fluorescent
emmision spectra originating from Trp residues. The method itself is highly reproducible
(intra- and interday), easy to perform (only two steps) and fast (under an hour), yielding
98% to 99% pure Tf with all buffers. Purified Tf was shown to have retained its ironbinding
capacity, as well as the ability to interact with TFR. Purified Tf also retained its
native three-dimensional structure. Described method for the isolation and purification of
Tf is fast, simple and highly reproducible, yielding a functional Tf of high purity in its
native state while offering the flexibility of using different buffer systems. All of these
features make this protocol a method of choice for the isolation and purification of Tf on a
semi-preparative scale.

AB  - Human serum tansferrin (hsTf) is a major circulatory protein crucial for the
transport/metabolism of Fe3+ ions. By sequestering and delivering ferric ions to target
tissues/cells hsTf maintains redox homeostasis. Oxidative stress (OS), one of the hallmarks
of (patho)physiological conditions, alters protein structure and function. The main role of
hsTf hinges on specific interaction with cellular Tf receptor (TfR) while other interactions
contribute to diverse functions. The aim of this study was to profile interacting partners of
hsTf in the samples of serum coming from patients diagnosed with a wide range of
pathological conditions with underlying OS status. Anti-hsTf pull-down samples were
analysed using mass spectrometry. Data went through analysis by appropriate
bioinformatic tools. Results reveal differences in expression of hsTf interacting proteins in
sample groups of patients suffering from kidney insufficiency subjected to dialysis
treatment (peritoneal-PD or hemo-HD) also with patients with gestational diabetes
compared to respective healthy sample groups. Colorectal cancer stage T3 versus T2 stage
shows an inverse distribution of expression profiles in comparison to healthy samples.
Most prominent differences are seen in hsTf interacting partners involved in the
complement and coagulation cascades and cholesterol metabolic pathways, suggesting a
multifaceted role of hsTf in these processes throughout the course of the disease.

AB  - In previous publications, we pointed out the importance of mannosylation of fibrinogen for the development of cardiovascular complications and fucosylation as a predictor of peritoneal membrane dysfunction in patients on peritoneal dialysis (PD). After a follow-up period of 30 months from the onset of the COVID-19 pandemic, we evaluated the significance of 1,25-dihydroxyvitamin D3 (calcitriol) therapy, primary disease, biochemical and hematologic analyzes, and previously performed glycan analysis by lectin-based microarray as predictors of mortality in this patient group. After univariate Cox regression analysis, diabetes mellitus (DM) and calcitriol therapy were found to be potential predictors of mortality. Additional multivariate Cox regression analysis confirmed that only DM was a predictor of mortality. Nevertheless, the use of calcitriol in therapy significantly reduced mortality in this patient group, as shown by the Kaplan–Meier survival curve. The presence of DM as a concomitant disease proved to be a strong predictor of fatal outcome in PD patients infected with SARS-CoV-2. This is the first study to indicate the importance and beneficial effect of calcitriol therapy on survival in PD patients with COVID-19 infection. In addition, this study points to the possibility that adverse thrombogenic events observed in PD patients during the pandemic may be caused by aberrant fibrinogen glycosylation.

AB  - The binding of a popular food supplement and well-known antioxidant, dihydro-alpha-lipoic acid (DHLA) to human serum albumin (HSA) was characterised. The binding was monitored by several spectroscopic methods together with the molecular docking approach. HSA was able to bind DHLA with moderate affinity, 1.00±0.05×104 M-1. Spectroscopic data demonstrated that the preferential binding site for DHLA on HSA is IIA (Sudlow I). Both experimental and molecular docking analysis identified electrostatic (salt bridges) and hydrogen bonds as the key interactions involved in DHLA binding to HSA. Molecular docking confirmed that the Sudlow I site could accommodate DHLA and that the ligand is bound to the protein in a specific conformation. The molecular dynamic simulation showed that the formed complex is stable. Binding of DHLA does not affect the structure of the protein, but it thermally stabilises HSA. Bound DHLA had no effect on the susceptibility of HSA to trypsin digestion. Since DHLA is a commonly used food supplement, knowledge of its pharmacokinetics and pharmacodynamic properties in an organism is very important. This study further expands it by providing a detailed analysis of its interaction with HSA, the primary drug transporter in the circulation.
AB  - У раду су описане карктеристике везивања дихидро-липоинске киселине (DHLA), познатог суплемента у исхрани и антиоксиданса, за албумин из серума људи (HSA). Процес везивања је праћен применом већег броја спектроскопских метода и молекул-
ским моделовањем. HSA везује DHLA умереним афинитетом, 1,00±0,05×104 M-1. Спектроскопски резултати су показали да је везујуће место IIA (Sudlow I) главно место везивања DHLA за HSA. Експериментални, као и резултати молекулског моделовања, су идентификовали електростатичке (сони мостови) и водоничне везе као главне типове
интеракција. Резултати молекулског моделовања су потврдили да и место Sudlow I може везати DHLA, која је у том случају у специфичној конформацији. Симулација молекулске динамике је показала да је формирани комплекс стабилан. Везивање DHLA не
утиче на структуру протеина, али повећава његову термалну стабилност. Везани DHLA не утиче на подложност HSA трипсинској дигестији. Како је DHLA уобичајен суплемент у исхрани, знање о његовим фармакоконетичким и фармакодинамичким особинама је веома важно.
