Radiation therapy (RT) plays an important role in the management of breast cancer. Radiation-induced fibrosis is a side effect of radiation therapy and may occur in up to 13% of the cases in patients (Radiother Oncol, 2009;90:80), fortunately usually is modest/localized and not associated with marked symptoms. However, occasionally, fibrosis can be moderate-to-severe, and cause clinically-meaningful symptoms. Read More

A multifunctional nanoparticulate system composed of methoxy poly(ethylene glycol)-poly(l-histidine)-d-α-vitamin E succinate (MPEG-PLH-VES) copolymers for encapsulation of doxorubicin (DOX) was elaborated with the aim of circumventing the multidrug resistance (MDR) in breast cancer treatment. The MPEG-PLH-VES nanoparticles (NPs) were subsequently functionalized with biotin motif for targeted drug delivery. The MPEG-PLH-VES copolymer exerts no obvious effect on the P-gp expression level of MCF-7/ADR but exhibited a significant influence on the loss of mitochondrial membrane potential, the reduction of intracellular ATP level, and the inhibition of P-gp ATPase activity of MCF-7/ADR cells.

The present study pertains to the possible adverse effects of penconazole exposure on the lung of adult rats, and to the potential ability of vitamin E (Vit E) in mitigating the toxicity induced by this fungicide. Male Wistar rats were divided into four groups of six animals each: Group I (Controls): rats drank distilled water; Group II (PEN): rats received, by gavage, 50 mg/kg body weight (1/40 LD) of penconazole every 2 days during 10 days; Group III (Vit E): rats received daily 100 mg α-tocopherol acetate/kg body weight during 10 days by gavage; and Group IV (Vit E + PEN): rats received both vitamin E (100 mg α-tocopherol acetate/kg body weight) and penconazole (50 mg/kg body weight), being vitamin E given as a daily dosage and penconazole every 2 days, by gavage during 10 days. Results showed that penconazole induced oxidative stress in the lung demonstrated by an increase in malondialdehyde (+77%), hydrogen peroxide (+58%) and advanced oxidation protein product (+22%) levels, as compared to the controls.

Oxidative stress is a known contributing factor in mitochondrial respiratory chain (RC) disease pathogenesis. Yet, no efficient means exists to objectively evaluate the comparative therapeutic efficacy or toxicity of different antioxidant compounds empirically used in human RC disease. We postulated that pre-clinical comparative analysis of diverse antioxidant drugs having suggested utility in primary RC disease using animal and cellular models of RC dysfunction may improve understanding of their integrated effects and physiologic mechanisms, and enable prioritization of lead antioxidant molecules to pursue in human clinical trials.

Periplocymarin (PPM), a cardiac glycoside, has a narrow therapeutic index, poor tumor selectivity and severe cardiovascular toxicity which hinder its wide clinical applications in cancer treatment. Herein, we report novel redox-responsive prodrug-nanoparticles (MPSSV-NPs) self-assembled by co-nanoprecipitation of PPM-vitamin E conjugate and a PEG derivative of linoleate (mPEG2000-LA) in water. It was found that the characteristics of PPM-vitamin E nanoparticles (PSSV-NPs) were improved through co-nanoprecipitation with increased percentages of mPEG2000-LA. Read More
