MTP-131 is currently being investigated in several phase II clinical trials. Preclinical studies in mouse models of HF have demonstrated efficacy using MTP-131. In a mouse model of HF induced by aortic constriction, MTP-131 improved left ventricular function, reduced hypertrophic remodelling, and re...
situated in the mitochondrial matrix, and Fo, located in the inner mitochondrial membrane. Complex V uses the energy created by the proton electrochemical gradient to phosphorylate ADP to ATP. This review covers the architecture, function and assembly of complex V. The role of complex V di...
Shrinkage of the mitochondrial matrix has been associated with triggering of cytocefflux from mitochondria and an inhibition of mitochondrial respiration47. Therefore, we proceeded to determine whether this is also the case when isolated mitochondria are incubated with HypF-N type A oligomers, and com...
The importance of Ca2+in the mitochondrial matrix ([Ca2+]m) for regulation of mitochondrial function was suggested as far back as 30 years ago [83]. Although the kinetics of mitochondrial Ca2+cycling and contribution to cytosolic [Ca2+] remain highly controversial, it is well accepted that Ca2...
The activity of the mitochondrial matrix marker enzyme citrate synthase (CS) was assayed spectrophotometrically by measuring coenzyme A formation at 412 nm, in cells at 30 ° C in the assay medium supplemented with 0.1% Triton X-100 as described previously [29]. 2.6. SDS-PAGE and Western ...
We analyzed the organization and function of mitochondrial DNA in a stable human cell line (ECV304, which is also known as T-24) containing mitochondria tagged with the yellow fluorescent protein. Mitochondrial DNA is organized in ~475 discrete foci cont
A Mn SOD (SOD2) isoform is expressed in most eukaryotes and it is exclusively located into the mitochondrial matrix [7]. Notably, mutations in SOD1 gene have been associated to the familial form of Amyotrophic Lateral Sclerosis (ALS) [8], [9], even though also wild type SOD1 is ...
Treatment of SK-N-AS cells with Abeta(1-42) resulted in an accumulation of the peptide in the mitochondrial matrix; SP-233 completely scavenged Abeta(1-42) from the matrix. In addition, SP-233 protected the cells against mitochondrial toxins targeting complexes IV and V of the respiratory ...

(trifluoromethoxy)phenylhydrazone). FCCP allows protons to flow back into the mitochondrial matrix, short-circuiting the MMP and stimulating the ETC complexes, which respond by increasing their activity to restore the cross-membrane proton gradient24. We stained control andZbtb11KO cells with TMRE ...
