Mitocondriopatías: las manifestaciones de una organela enferma. ¿Quién hace el diagnóstico? [PDF]

, 2006
Las enfermedades mitocondriales son relativamente comunes y resultan de defectos en la cadena respiratoria de esa organela. Sus manifestaciones pueden ser multisistémicas o localizadas en un solo tejido. Además, pueden ser adquiridas en forma esporádica

Proteostasis of organelles in aging and disease

The FEBS Journal, EarlyView.
Cells rely on regulated proteostasis mechanisms to keep their internal compartments functioning properly. When these mechanisms fail, damaged proteins accumulate, disrupting organelles, such as the nucleus, mitochondria, endoplasmic reticulum, Golgi, and lysosomes, as well as membraneless organelles, such as stress granules, processing bodies, the ...

DESCRIÇÃO DE DANOS ULTRAESTRUTURAIS EM ESPERMATOZOIDES CANINOS CONGELADOS-DESCONGELADOS

Ciência Animal Brasileira, 2009
Apesar dos avanços na microscopia eletrônica de transmissão (MET), existem poucos estudos apresentando uma descrição sistemática do espermatozoide canino, os quais estão focados apenas na cabeça espermática. Objetivou-se, com o presente estudo, descrever

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

FEBS 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 ...

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

FEBS 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 ...

TbTim20 facilitates protein import at a low membrane potential in trypanosomes lacking the mitochondrial genome

The FEBS Journal, Volume 293, Issue 6, Page 1771-1784, March 2026.
Protein import into mitochondria relies on TIM complexes and the membrane potential. Trypanosoma brucei has a unique TIM complex, and the role of one subunit, TbTim20, has remained unclear. Here, we show that TbTim20 is essential in cells lacking mitochondrial DNA. The importance of TbTim20 increases as the membrane potential decreases.
