An unexpected alternative viologen electron mediator site in tungsten‐containing formate dehydrogenase

open access: yesFEBS Letters, EarlyView.
An unexpected alternative interaction site for ethyl viologen was identified in formate dehydrogenase 1 from Methylorubrum extorquens. Combined mutagenesis, kinetic analysis, and docking revealed that aromatic residues near an iron–sulfur cluster enable flavin mononucleotide‐independent electron transfer, offering a framework for engineering improved ...

Incremental Modification in the Existing Approaches for Affinity Chromatographic Enrichment of Phosphoproteins Improves Their Profile in Liquid Chromatography‐Tandem Mass Spectrometry Analysis

open access: yesAnalytical Science Advances
Cell signalling is a vital process in cell physiology, which is driven by protein phosphorylation. Global phosphoproteome analysis by liquid chromatography‐tandem mass spectrometry (LC‐MS/MS) has thus gained importance in cell signalling research ...

Consecutive Affinity and Ion-Exchange Chromatography for AAV9 Vectors Purification

open access: yesBiomedicines
Background: Irrespective of the rapid development of AAV-based gene therapy, the production of clinical-grade vectors has a bottleneck resulting from product-related impurities such as empty and partially filled capsids, which lack a functional ...

Extending the Affinity Range of Weak Affinity Chromatography for the Identification of Weak Ligands Targeting Membrane Proteins

open access: yesMolecules, 2023
The identification of weak-affinity ligands targeting membrane proteins is of great interest in Fragment-Based Drug Design (FBDD). Recently, miniaturized weak affinity chromatography (WAC) has been proposed as a valuable tool to study interactions ...

TRAIL‐PEG‐Apt‐PLGA nanosystem as an aptamer‐targeted drug delivery system potential for triple‐negative breast cancer therapy using in vivo mouse model

open access: yesMolecular Oncology, EarlyView.
Aptamers are used both therapeutically and as targeting agents in cancer treatment. We developed an aptamer‐targeted PLGA–TRAIL nanosystem that exhibited superior therapeutic efficacy in NOD/SCID breast cancer models. This nanosystem represents a novel biotechnological drug candidate for suppressing resistance development in breast cancer.

Subfractionation of human high density lipoproteins by heparin-Sepharose affinity chromatography.

open access: yesJournal of Lipid Research, 1980
A reproducible and quantitative subfractionation of human high density lipoproteins (HDL) by heparin-Sepharose affinity chromatography has been developed. Two elution methods (A and B) were used to subfractionate HDL(2) (d 1.063-1.125 g/ml) or total HDL (

APPLICATION OF IMMUNOGLOBULIN-BINDING PROTEINS A, G, L IN THE AFFINITY CHROMATOGRAPHY [PDF]

open access: yesBiotechnologia Acta, 2014
Proteins A, G and L are native or recombinant proteins of microbial origin that bind to mammalian immunoglobulins. Preferably recombinant variants of proteins A, G, L are used in biotechnology for affinity sorbents production. Сomparative characteristics

COMP–PMEPA1 axis promotes epithelial‐to‐mesenchymal transition in breast cancer cells

open access: yesMolecular Oncology, EarlyView.
This study reveals that cartilage oligomeric matrix protein (COMP) promotes epithelial‐to‐mesenchymal transition (EMT) in breast cancer. We identify PMEPA1 (protein TMEPAI) as a novel COMP‐binding partner that mediates EMT via binding to the TSP domains of COMP, establishing the COMP–PMEPA1 axis as a key EMT driver in breast cancer.

EDNRB‐dependent endothelin signaling reduces proliferation and promotes proneural‐to‐mesenchymal transition in gliomas

open access: yesMolecular Oncology, EarlyView.
Glioma cells mainly express the endothelin receptor EDNRB, while EDNRA is restricted to a perivascular tumor subpopulation. Endothelin signaling reduces glioma cell proliferation while promoting migration and a proneural‐to‐mesenchymal transition associated with poor prognosis. This pathway activates Ca2+, K+, ERK, and STAT3 signalings and is regulated

Investigation of different molecular forms of IGFBP-1 using immobilised metal-, immuno- and lectin-affinity chromatography [PDF]

open access: yesJournal of the Serbian Chemical Society, 2010
Insulin-like growth factor-binding protein 1 (IGFBP-1) is a member of a family of six homologous proteins that regulate the action of the insulin-like growth factors.
