Abstract

This research explores the impact of arsenic exposure on serum protein profiles in type 2 diabetes patients, with an emphasis on the AS3MT protein as a biomarker. Utilizing Bradford protein assay, SDS-PAGE, HPLC, and mass spectrometry, we quantified and analyzed variations in serum protein levels, focusing on differences between control groups (82.94 ± 8.03 µg/mL) and diabetic patients (96.95 ± 5.02 µg/mL) of high arsenic exposed in areas Kasur and Lahore, Punjab, Pakistan. The study revealed a significant increase in total serum proteins and specifically identified elevated levels of AS3MT in the diabetic group compared to controls. By using 15% gel, proteins were separated, and bands were visible at 42KD. Further investigations using HPLC provided a detailed chromatographic profile of AS3MT, isolating this protein effectively and displaying its heightened abundance through a marked peak within the sample chromatograms. Additionally, intact mass and tryptic digestion profiles analyzed by mass spectrometry (molecular weight of 41,747.79 D) further corroborated the identity and modification of AS3MT in the context of arsenic exposure. ELISA was used for the quantification of AS3MT protein concentration, and a 260% increase was confirmed in the diabetic group exposed to arsenic. These findings suggested that arsenic exposure significantly alters AS3MT protein and serum protein levels in diabetic patients, supporting the hypothesis that AS3MT can serve as a biomarker for arsenic-induced diabetic conditions.

期刊介绍: Biological Trace Element Research provides a much-needed central forum for the emergent, interdisciplinary field of research on the biological, environmental, and biomedical roles of trace elements. Rather than confine itself to biochemistry, the journal emphasizes the integrative aspects of trace metal research in all appropriate fields, publishing human and animal nutritional studies devoted to the fundamental chemistry and biochemistry at issue as well as to the elucidation of the relevant aspects of preventive medicine, epidemiology, clinical chemistry, agriculture, endocrinology, animal science, pharmacology, microbiology, toxicology, virology, marine biology, sensory physiology, developmental biology, and related fields.
