The mitochondrial dysfunction owing to CoQ10 deficiency induces a stable survival adaptation of somatic cells in patients at early or postnatal development by epigenetic modifications of chromatin.
These results indicate that the mitochondrial dysfunction owing to CoQ10 deficiency induces a stable survival adaptation of somatic cells in patients at early or postnatal development, and we speculate that cells unable to institute, or to maintain, this survival mechanism during differentiation will die, contributing to the pathological phenotype.
Sickle cell anemia (SCA) is characterized by a marked endothelial dysfunction, owing to many factors.
To investigate the stable genetic cause responsible for the survival adaptation to mitochondrial dysfunction owing to CoQ10 deficiency.
In the chronic phase of Chagas disease, TNF- α seems to be closely related to cardiac dysfunction owing to its negative inotropic effect, in both experimental models [ 38] and humans [ 39].
To address the in vivo role of CHK2 in signaling telomere dysfunction owing to Trf1 deficiency, we crossed Trf1 Δ/Δ K5Cre mice (Martinez et al., 2009) with mice with whole-body Chk2 deletion, Chk2 −/− (Hirao et al., 2002).
Here, we studied the role of the checkpoint kinase Chk2 in mediating the in vivo phenotypes induced by telomere dysfunction owing to either critical telomere shortening (Terc deficiency) or severe telomere uncapping (Trf1 deficiency).
Several cell models document the accumulation of the full-length amyloid precursor protein (APP) in the outer mitochondrial membrane as another molecular event that is responsible for mitochondrial dysfunction, owing to its translocational arrest (Ref. 68).
The ADAM questionnaire failed to detect an increase in hypogonadal symptoms in groups with lower total testosterone levels, but the questionnaire does not correlate closely with testosterone levels, and men with diabetes have a high level of false-positive hypogonadal symptoms (2) such as erectile dysfunction owing to vascular and neuropathic factors, medications, and depression.
This information provided us with a plausible explanation that WTH3's low expression observed in MCF7/AdrR could be the result of p53 dysfunction owing to the mini deletion in its DNA-binding domain, whereas MCF7/WT, which contains the wild-type p53 gene, expressed a relatively high level of WTH3 (Norbury and Zhivotovsky, 2004).
