Poly-MVA attenuates 7,12- dimethylbenz[a]anthracene initiated and croton oil promoted skin papilloma formation on mice skin.

Chemopreventive agents which exhibit activities such as anti-inflammation, inhibition of carcinogen induced mutagenesis and scavenging of free radical might play a decisive role in the inhibition of chemical carcinogenesis either at the initiation or promotion stage. Many synthesized palladium (Pd) complexes tested experimentally for antitumor activity are found effective. Poly-MVA is a liquid blend preparation containing B complex vitamins, ruthenium with Pd complexed with alpha lipoic acid as the major ingredients.

Late Administration of a Palladium Lipoic Acid Complex (POLY-MVA) Modifies Cardiac Mitochondria but Not Functional or Structural Manifestations of Radiation-Induced Heart Disease in a Rat Model.

Exposure of the heart to ionizing radiation can cause adverse myocardial remodeling. In small animal models, local heart irradiation causes persistent alterations in cardiac mitochondrial function and swelling. POLY-MVA is a dietary supplement that contains a palladium lipoic acid complex that targets mitochondrial complex I and has been demonstrated to have greater redox potential than lipoic acid alone.

Antitumor Effects of Palladium-α-Lipoic Acid Complex Formulation as an Adjunct in Radiotherapy.

Several investigations have been initiated to enhance the antitumor effect of radiation and ameliorate its adverse effects such as reducing blood cell counts and causing DNA damage in normal cells. Compounds that enhance the antitumor activity of radiation without reducing blood cell counts or damaging DNA in normal cells can be of immense use as an adjunct in radiotherapy. We evaluated the antitumor effect of a specific set of minerals, vitamins, and amino acids (Poly-MVA) (2 mL/kg, per os), with and without radiation, against Dalton's lymphoma ascites (DLA) and Ehrlich's ascites carcinoma (EAC) cell lines that were transplanted in a solid-tumor model.

Effect of palladium α-lipoic acid complex on energy in the brain mitochondria of aged rats.

Context: According to the mitochondrial mutation theory of aging, the impairment of mitochondrial functions and decline of cellular bioenergetics are induced by highly reactive oxygen species (ROS). Supplementation with antioxidants may protect mitochondria against respiration-linked oxidative stress and reduce decay by preserving genomic and structural integrity. Several clinical studies have reported beneficial effects of α-lipoic acid (LA) administration in individuals with Alzheimer's disease, particularly improving their spatial orientation; however, no studies have been reported on the effects of palladium α-lipoic acid (Pd-LA).

Regulation of ischemic cell death by the lipoic acid-palladium complex, Poly MVA, in gerbils.

Modulation of ischemic cell death can be accomplished via a multitude of mechanisms, such as quenching radical species, providing alternative energy sources, or altering glutamate excitation. Transient cerebral ischemia will induce apoptotic cell death selectively to hippocampal cornus ammon's field 1 of the hippocampus (CA1) pyramidal cells, while neighboring CA3 and dentate neurons are spared. Poly MVA is a dietary supplement based on the nontoxic chemotherapeutic lipoic acid-palladium complex (LAPd).

Vasoactive intestinal peptide attenuates cytochrome c translocation, and apoptosis, in rat hippocampal stem cells.

While widely distributed in the brain, one area with concentrated levels of vasoactive intestinal peptide (VIP) is the hippocampus. In this study, rat hippocampal stem cells were used to examine VIP's effects on apoptotic cell death induced by withdrawal of trophic support. In the apoptotic cascade, the translocation of cytochrome c from the mitochondria to the cytoplasm activates caspases, resulting in cell death.

Modulation of apoptotic regulatory proteins and early activation of cytochrome C following systemic 3-nitropropionic acid administration.

The present study utilized the administration of the mitochondrial toxin, 3-nitropropionic acid (3-NP), to mimic the pathology associated with Huntington's disease (HD). 3-NP causes striatal cell degeneration via the inhibition of succinate dehydrogenase. There is growing evidence suggesting the role of apoptosis in 3-NP cell death.
