A Spatially Resolved View on the Aging Substantia nigra: An Exploratory Proteomic Study
Advanced Biology, EarlyView.Although aging is the most important risk factor for several neurodegenerative diseases, the molecular effects of physiological aging are still understudied. By applying spatially‐resolved proteomic analyses of the human substantia nigra pars compacta, alterations in vesicular trafficking and mitochondrial proteins are observed, as well as reduced ...

Exposure to Toxic Heavy Metals Can Influence Homocysteine Metabolism?
Antioxidants, 2019 Background: Homocysteine is a sulfur amino acid whose metabolism is activated in two pathways: remethylation to methionine, which requires folate and vitamin B12, and transsulfuration to cystathionine, which needs pyridoxal-5’-phosphate.

Quantitative analysis of in vivo methionine oxidation of the human proteome
bioRxiv, 2019 The oxidation of methionine is an important posttranslational modification of proteins with numerous roles in physiology and pathology. However, the quantitative analysis of methionine oxidation on a proteome-wide scale has been hampered by technical ...

A Sustainable Biotechnology Approach for Mineral Separation
Advanced Functional Materials, EarlyView.Silver‑binding peptides are first identified through phage‐display screening, and then engineered into multifunctional and responsive peptides or proteins. These tailored biomolecules can selectively capture and aggregate silver particles or ions from complex mixtures, enabling rapid and efficient silver separation and recovery.
