Recent Advances (2023–2025) of Capillary Electrophoresis‐Mass Spectrometry (CE‐MS) for Top‐Down Proteomics

Mass Spectrometry Reviews, EarlyView.
ABSTRACT Top‐down proteomics (TDP) characterizes proteoforms in cells, tissues, and biofluids, in discovery mode and on a global scale, requiring analytical tools with high peak capacity for proteoform separation and high sensitivity for proteoform detection, given the extremely high proteoform complexity and wide proteoform concentration dynamic range.

Evaluation of Benzenesulfonamide Derivatives; Quinazoline and Sulfonamide Selectively Targeting Carbonic Anhydrase XII for Tumor Microenvironment Modulation in Human Breast Cancer Cells

Al-Mustansiriyah Journal of Pharmaceutical Sciences
Tumor cells evolve adaptive mechanisms to function optimally within an acidic microenvironment. This adaptation is driven by the enhanced metabolic activity of tumors, which frequently results in acidosis and hypoxia.

Recent Advances in Top‐Down Proteomics for Single‐Cell Research

Mass Spectrometry Reviews, EarlyView.
ABSTRACT Individual cells have distinctive molecular characteristics, including biologically relevant proteoforms. Although single‐cell (SC) molecular omics offer unprecedented insights into cellular heterogeneity and function, the characterization of proteoforms in SCs remains an uncharted territory.

Movement Disorders in Developmental and Epileptic Encephalopathies

Movement Disorders Clinical Practice, EarlyView.
Abstract Background Monogenic developmental and epileptic encephalopathies (DEE) frequently feature co‐occurring movement disorders. Gene discovery has expanded epilepsy‐dyskinesia syndromes (EDS) from classic associations such as stereotypies in Rett syndrome to PRRT2‐related infantile seizures with paroxysmal dyskinesia and crouched gait in SCN1A ...

CARBONIC ANHYDRASE AS A MARKER OF OSTEOCLAST ACTIVITY IN THE REPAIR ZONE OF LONG BONE FRACTURE

Acta Biomedica Scientifica, 2012
In an experimental model of long bone fractures studied osteoclastic activity in the fracture zone. We used histological staining methods and histochemical staining with antibodies to carbonic anhydrase type II.

Osteoarthritis: An Immuno‐Inflammatory Disease‐Mechanisms of Immune Cell Dysregulation and Potential Therapeutic Strategies

Med Research, EarlyView.
This review summarizes the immuno‐inflammatory mechanisms driving the pathogenesis of osteoarthritis (OA), extending beyond the traditional view of OA as a purely degenerative disease to incorporate immune cell infiltration, inflammatory factor release, and the formation of a chronic low‐grade inflammatory microenvironment.

Increased oxidation-related glutathionylation and carbonic anhydrase activity in endometriosis.

, 2014
This study examined the possible involvement of carbonic anhydrase activation in response to an endometriosis-related increase in oxidative stress. Peripheral blood samples obtained from 27 healthy controls and 30 endometriosis patients, classified as ...

Parallel Analysis of Acidic and Basic Proteoforms in Cell Lysates via Native Cation and Anion Exchange Chromatography—Native Mass Spectrometry

PROTEOMICS, EarlyView.
ABSTRACT Comprehensive characterization of proteoforms in complex biological systems remains a significant challenge. While native ion‐exchange chromatography (IEC) hyphenated with native mass spectrometry (nMS) is a powerful tool for resolving proteoforms, three critical limitations persist: restricted volatile buffers causing nonlinear pH gradients ...

Electron spin resonance studies on cobalt carbonic anhydrase-substrate complexes

, 1997
The native zinc atom of bovine erythrocyte carbonic anhydrase purified by affinity choromatography was removed by dialysis against pyridine 2,6-dicarboxylic acid. Cobalt carbonic anhydrase was prepared from the zinc-free apoenzyme. The binding conditions

Unspecific Molecular Adsorption (UMA) Sample Preparation Method for Bottom‐up and Whole Protein Analysis: The Foundation

PROTEOMICS, EarlyView.
ABSTRACT The protein sample preparation methods for shotgun proteomics are nowadays well‐established unlike the ones for whole protein analysis. The goal of my work has been to create a simple methodology which provides a single uncomplicated sample preparation tool for these two fields. Nowadays the bulk of proteomics work is done using detergents for
