چکیده

By using a potential-dependent J-aggregate-forming delocalized lipophilic cation, 5,5',6,6'-tetrachloro-1,1',3,3'-tetraethylbenzimidazolocarbocyanine++ + iodide (JC-1), we find that membrane potentials across mitochondria in a living cell can be heterogeneous. Remarkably, even within a long contiguous mitochondrion, regional heterogeneity in membrane potentials appears to be possible.

Alterations in mitochondrial structure and function are early events of dexamethasone-induced thymocyte apoptosis

In this paper we used a multiparametric approach to analyze extensively the events occurring during apoptotic cell death of thymocytes, and furthermore, we asked whether alterations in mitochondrial structure and function are occurring in early stages of apoptosis. A multiparametric quantitative analysis was performed on normal or apoptotic thymocytes emerging from a few-hour culture performed ...

Evidences for a new cation channel in the brain mitochondrial inner membrane

Introduction: Previous studies and our works have indicated several cation channels in the rat brain mitochondrial inner membrane. In this work, we report the single-channel characterization of a cation channel from the rat brain mitochondrial inner membrane incorporated into a planar lipid bilayer. Methods: After removing and homogenizing the adult rat brain, its supernatant was centrifuged...

Baicalin Induced Dendritic Cell Apoptosis in Vitro

This study was aimed to investigate the effects of baicalin (BA), a major flavonoid constituent found in the herb Baikal skullcap, on dendritic cells (DCs). DCs were generated by culturing murine bone marrow (BM) cells for 6 days with granulocyte-macrophage colony-stimulating factor and interleukin (IL)-4, and lipopolysaccharide (LPS) was added on day 5 to stimulate DCs maturation. The expressi...

Phenotypic Changes in Mitochondrial Membrane Potential (Δψm) during Valinomycin-Induced Depolarisation and Apoptosis

A large body of evidence has implicated mitochondria in control of cell death, where key apoptotic mechanisms involve change in mitochondrial membrane permeability and depolarisation of mitochondrial membrane potential (∆ψm). Assessment of ∆ψm is traditionally conducted using the lipophilic cation JC-1 on the flow cytometer or by fluorescent microscopy. Here we assess JC-1 aggregation using the...

Cryopreservation of metaphase II human oocytes effects mitochondrial membrane potential: implications for developmental competence.

BACKGROUND Current outcome results with embryos derived from thawed MII human oocyes are significantly lower than with embryos cryopreserved at the pronuclear stage. Here, we investigated whether freezing-thawing was associated with changes in oocyte mitochondrial polarity (DeltaPsim) that could influence competence by altering ATP levels or the ability of the cytoplasm to regulate intracellula...
