As we gain a better understanding of the factors affecting cancer etiology, we can design improved treatment strategies. Over the past three to four decades, there have been numerous successful efforts in recognizing important cellular proteins essential in cancer growth and therefore these proteins have been targeted for cancer treatment. However, studies(More)
Metal ions accumulate in the brain with aging and in several neurodegenerative diseases. Aside from the copper storage disease, Wilson's disease, recent attention has focused on the accumulation of zinc, copper and iron in the Alzheimer's disease (AD) brain and the accumulation of iron in Parkinson's disease. In particular, the parenchymal deposition of(More)
Serum and tumor copper levels are significantly elevated in a variety of malignancies including breast, ovarian, gastric, lung, and leukemia. D-Penicillamine (D-pen), a copper-chelating agent, at low concentrations in the presence of copper generates concentration-dependent cytotoxic hydrogen peroxide (H(2)O(2)). The purpose of these studies was to(More)
The objectives of these studies were to investigate and compare solid lipid nanoparticles (SLNs) of two anthracyclines, idarubicin (IDA) and doxorubicin (DOX), against Pgp-mediated multiple drug resistance (MDR) in-vitro and in-vivo using different human and murine cancer cell models. IDA and DOX SLNs were developed from warm microemulsion precursors(More)
The purpose of this study was to compare the combination (Paclitaxel + 5-FU microspheres) with a single drug chemotherapy (Paclitaxel and 5-FU microspheres) against metastatic breast cancer cell line (MDA-MB 435 S). The physicochemical characteristics of the microspheres (i.e. encapsulation efficiency, particle size distribution, in vitro release, thermal(More)
D-Penicillamine is a potent copper (Cu) chelating agent. D-Pen reduces Cu(II) to Cu(I) in the process of chelation while at the same time being oxidized to D-penicillamine disulfide. It has been proposed that hydrogen peroxide is generated during this process. However, definitive experimental proof that hydrogen peroxide is generated remains lacking. Thus,(More)
The purpose of these studies was to investigate and compare the composition, stability, antioxidant and anticancer properties and mechanisms of anthocyanin-containing blackberry extracts (ACEs) from selected cultivars and using different extraction methods. ACEs were analyzed for total anthocyanin and phenolics content, polymeric color, and total(More)
D-Penicillamine (D-pen) is an established copper chelator. We have recently shown that the copper-catalyzed D-pen oxidation generates concentration-dependent hydrogen peroxide (H 2O 2). Additionally, D-pen coincubated with cupric sulfate resulted in cytotoxicity in human leukemia and breast cancer cells due to the extracellular generation of reactive oxygen(More)
Roller compaction parameters' impact on granules and tableting properties of coprocessed Avicel® DG [ADG], a physical mixture of the two components at the same composition present in ADG [PADCP], and microcrystalline cellulose and Kollidon® VA-64 Fine physical mixture [KVA64] was quantified by analysis of variance (ANOVA) and multivariate methods. Roller(More)
