•The presence of MAMs and matrix granules in AML cell lines is evidence that there are active communication processes between endoplasmic reticulum mitochondria AML. •HL60 carrying high levels favor conserved has a higher sensitivity to drugs targeting (rotenone/antimycin). •Conversely, K562, the ASXL1 mutation, exhibits decrease numbers granules, MAM, MDV precursors associated with chemoresist...

39 An increase in oxygen tension at birth is one of the key signals that initiate pulmonary 40 vasodilation in the fetal lung. We investigated the hypothesis that targeting endothelial 41 nitric oxide synthase (eNOS) to the mitochondrial outer membrane regulates reactive 42 oxygen species (ROS) formation in the fetal pulmonary artery endothelial cells (PAEC) 43 during this transition. We isolat...

results the results reveal that pq can decrease mitochondrial viability, deplete gsh content, increase mitochondrial ros formation, and enhance lpo and mitochondrial membrane damage. the pretreatment of mitochondria with ng has the ability to reduce the toxic effects of pq in isolated mitochondria. background paraquat (pq) is a dipyridyl herbicide that sustains damage due to redox cycling. an i...

The fetotoxic effects of maternal ethanol (E) consumption have been documented for over two decades, yet the mechanisms underlying this devastating phenomenon remain uncertain. The wide variety of cellular/biochemical effects of E on fetal tissues is itself a puzzle and strongly suggests that fetotoxic responses to E reflect a multifactorial setting. Many of these responses can be conceptually ...

For the purpose of studying the aging changes of macromolecular synthesis in the colonic cells of experimental animals, we studied 10 groups of aging mice during aging from fetal day 19 to postnatal month 24. They were injected with 3 H-uridine, a precursor for RNA synthesis, sacrificed and the colonic tissues were taken out, fixed and processed for light and electron microscopic radioautograph...

Lung cancer is the most commonly diagnosed with a high mortality rate. Cisplatin one of important chemotherapeutic agents for treatment lung patients, especially in advanced stages. Recent studies show that cisplatin may interact mitochondria to induce apoptosis, which partly account its cytotoxicity. In study, we explored effect resistin on cisplatin-induced cytotoxicity A549 cells and assesse...

Fifteen therapeutically aborted fetuses at the 5th-8th gestation month from the endemic fluorosis area were compared with those from the non-endemic area. Stereological study of the brains showed that the numerical density of volume of the neurons and the undifferentiated neuroblasts as well as the nucleus-cytoplasm ratio of the neurons were increased. The mean volume of the neurons was reduced...

doxorubicin (dox) is an anthracycline antibiotic that has been used for a long time in therapy of an array of human malignancies either alone or in combination with other cytotoxic agents. the dose-dependent cardiotoxicity of dox significantly limits its anticancer efficacies. oxidative stress caused by enhanced production of reactive oxygen species is an important contributor to dox mitochondr...

sepsis is a systemic inflammatory response to infection. sepsis, which can lead to severe sepsis, septic shock, and multiple organ dysfunction syndrome, is an important cause of mortality. pathogenesis is extremely complex. in recent years, cell hypoxia caused by mitochondrial dysfunction has become a hot research field. sepsis damages the structure and function of mitochondria,conversely, mito...

Using PCR, we found that normal heart muscle and brain from adult human individuals contain low levels of a specific mitochondrial DNA deletion, previously found only in patients affected with certain types of neuromuscular disease. This deletion was not observed in fetal heart or brain. Experimental tests support the idea that the deletion exists in vivo in adult mitochondria and is not an in ...
