Comparative analysis of metabolic and functional cardiac alterations in diet‐ and genetically induced mouse models of cardiac dysfunction

open access: yesThe FEBS Journal, Volume 293, Issue 8, Page 2454-2477, April 2026.
Dietary and genetic stress trigger different routes to heart failure. In mice, a carbohydrate‐free high‐fat diet caused mitochondrial dysfunction and impaired energy production with preserved pumping function, while genetic obesity led to heart enlargement, fibrosis, and reduced function.

Molecular bases of circadian magnesium rhythms across eukaryotes

open access: yesFEBS Letters, Volume 600, Issue 6, Page 894-909, March 2026.
Circadian rhythms in intracellular [Mg2+] exist across eukaryotic kingdoms. Central roles for Mg2+ in metabolism suggest that Mg2+ rhythms could regulate daily cellular energy and metabolism. In this Perspective paper, we propose that ancestral prokaryotic transport proteins could be responsible for mediating Mg2+ rhythms and posit a feedback model ...

Homologous expression and purification of human HAX‐1 for structural studies

open access: yesFEBS Open Bio, Volume 16, Issue 3, Page 450-460, March 2026.
This research protocol provides detailed instructions for cloning, expressing, and purifying large quantities of the intrinsically disordered human HAX‐1 protein, N‐terminally fused to a cleavable superfolder GFP, from mammalian cells. HAX‐1 is predicted to undergo posttranslational modifications and to interact with membranes, various cellular ...

La mitocondria como un sistema de multicapas ópticas para la propagación de los campos electromagnéticos

open access: yesEntramado, 2016
El artículo propone estudiar la propagación de los campos electromagnéticos a través de la mitocondria. Se presenta un modelo simplifica - do de la mitocondria como un sistema periódico de multicapas de índices de refracción alternantes.

Dietary nitrate and nitrite protect against doxorubicin‐induced cardiac fibrosis and oxidative protein damage in tumor‐bearing mice

open access: yesFEBS Open Bio, Volume 16, Issue 3, Page 584-594, March 2026.
Chemotherapies such as doxorubicin can have toxic effects on healthy cardiovascular/heart tissue. Following up on a doxorubicin toxicity study in mice without tumors where nitrate water was cardioprotective (lessened toxicity), this study with tumor‐bearing mice undergoing doxorubicin treatment showed no negative effect of nitrate and nitrite on drug ...
