Vitamin D deficiency induces erectile dysfunction: Role of superoxide and Slpi

open access: yesBritish Journal of Pharmacology, Volume 182, Issue 15, Page 3669-3687, August 2025.
Background and Purpose Epidemiological studies suggest a relationship between vitamin D deficiency and erectile dysfunction (ED). We hypothesized that vitamin D deficiency or vitamin D receptor (VDR) knockout causes ED and analysed the underlying molecular mechanisms.

Buffer 4‐Ethylmorpholinium/Acetate: Exploring a New Alternative Buffer for Native Mass Spectrometry

open access: yesRapid Communications in Mass Spectrometry, Volume 39, Issue 14, 30 July 2025.
ABSTRACT Rationale To perform native mass spectrometry (MS) studies, there are a limited number of volatile and electrospray ionization (ESI)‐MS compatible solutions, such as ammonium bicarbonate and ammonium acetate (AA). These solutions could induce the unfolding of proteins due to the formation of CO2 bubbles or induced acidification during ESI ...

Spectroscopic Interrogation of Thiolate Hydrogen Bonding in the CO Sensor Protein CooA: Implications for Thiolate Ligation Stability and Cytochrome P450 Function

open access: yesChemistry – A European Journal, Volume 31, Issue 37, July 2, 2025.
Heme proteins are important biomolecules. Proximal cysteine thiolate ligation is found both in heme enzymes such as cytochromes P450 (CYP) and regulatory proteins such as CooA, a CO sensor. The role of H‐bonding to this cysteine is explored in CooA, including variants, and CYP119 using optical and paramagnetic resonance spectroscopies, which highlight ...
