Mitochondrial ultrastructural and atpase changes during the life cycle of Ascaris Suum

open access: yesMemorias do Instituto Oswaldo Cruz, 1982
Ultrastructural morphology and ATPase specific activities of mitochondria isolated from 1-celled fertilized egg, 10-day embryo, 21-day infective larvae and adult body wall muscle of Ascaris suum and rat liver were determined and compared.

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 ...

Novel heterozygous mutation in the steroidogenic acute regulatory protein gene in a 46,XY patient with congenital lipoid adrenal hyperplasia [PDF]

open access: yes, 2013
StAR forma parte del complejo multiproteico transduceosoma, encargado del transporte de colesterol y que facilita su entrada a la mitocondria. Mutaciones recesivas en el gen STAR causan formas clásicas y no clásicas de hiperplasia adrenal congénita ...

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 ...

LAS MITOCONDRIAS EN LA TRANSFORMACIÓN CELULAR DEL EPITELIO MAMARIO [PDF]

open access: yesRevista chilena de obstetricia y ginecología, 2008
Antecedentes: La adquisición del fenotipo metastático es el resultado de la potente acción generada por on-cogenes transformantes sobre una célula normal los cuales con la consiguiente expresión de oncoproteínas determinan drásticos cambios tanto en la morfología como en los volúmenes de los componentes celulares, generando una célula con diferente ...

Bases moleculares de las enfermedades mitocondriales Molecular basis of mitochondrial diseases

open access: yesMedisan, 2012
Las mitocondrias son orgánulos subcelulares que tienen como misión principal la producción de energía, los cuales contienen su propio sistema genético que codifica un número pequeño de proteínas que forman parte del sistema de fosforilación oxidativa. En

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 ...
