Nanoliposome can be designed as a drug delivery carrier to improve the pharmacological and therapeutic properties of drug administration. (188)Re-labeled nanoliposomes are useful for diagnostic imaging as well as for targeted radionuclide therapy. In this study, the in vivo nuclear imaging, pharmacokinetics and biodistribution of administered nanoliposomes were investigated as drug and radionuc...

Doxorubicin, a chemotherapeutic agent, inhibits the religation step of topoisomerase II (Top2). However, the downstream ramifications of this action are unknown. Here we performed epistasis analyses of top2 with 63 genes representing doxorubicin resistance (DXR) genes in fission yeast and revealed a subset that synergistically collaborate with Top2 to confer DXR. Our findings show that the chro...

PURPOSE The incorporation of doxorubicin in long-circulating sterically stabilized liposomes (SSL-DXR) alters the pharmacokinetics and biodistribution of doxorubicin and therefore has the potential to alter the pharmacologic properties of doxorubicin. Previously, we showed that repetitive administration of SSL-DXR alters tumor vascular permeability. EXPERIMENTAL DESIGN Here, we investigated t...

Alopecia, accompanied by skin dryness, is one of the distressing side effects often occurring in chemotherapy-treated cancer patients. Little is known of the effects of chemotherapy on sebaceous glands, despite their importance in hair follicle homeostasis. This study investigates sebaceous gland morphology and the response of SZ95 sebaceous gland cell line to doxorubicin (DXR) treatment. The m...

Purpose: To investigate the potential genoprotective effects of thymoquinone (TQ) on the cytotoxicity and genotoxicity-induced by doxorubicin (DXR), a key chemotherapeutic drug. Methods: Isolated human peripheral leukocytes were treated with varying concentrations of TQ (5.0, 10.0, or 20.0 μM) alone or in combination with DXR (0.15 μg/mL). Comet assays and apoptotic cell studies were performed ...

The dibenzylbutyrolactolic lignan (-)-cubebin was isolated from dry seeds of Piper cubeba L. (Piperaceae). (-)-Cubebin possesses anti-inflammatory, analgesic and antimicrobial activities. Doxorubicin (DXR) is a topoisomerase-interactive agent that may induce single- and double-strand breaks, intercalate into the DNA and generate oxygen free radicals. Here, we examine the mutagenicity and recomb...

The poor selective toxicity of chemotherapeutic anticancer drugs leads to dose-limiting side effects that compromise clinical outcome. Solid tumors recruit new blood vessels to support tumor growth, and unique epitopes expressed on tumor endothelial cells can function as targets for the anti-angiogenic therapy of cancer. An NGR peptide that targets aminopeptidase N, a marker of angiogenic endot...

The present study aims to investigate whether rutin and hesperidin could protect against acute doxorubicin (DXR)-induced testicular toxicity. Doxorubicin (DXR)– administered rats (25 mg/ kg; three times interaperitoneally/week for two weeks) were pretreated with rutin and/or hesperidin, (50 mg/ kg body weight) three times per week for three weeks and DXR 25mg/kg b.wt three times per week (at th...

The consumption of organic tomatoes (ORTs) reduces the risk of harmful effects to humans and the environment caused by exposure to toxic agrochemicals. In this study, we used the somatic mutation and recombination test (SMART) of wing spots in Drosophila melanogaster to evaluate the genotoxicity of ORT and the effect of cotreatment with ORT on the genotoxicity of Doxorubicin(®) (DXR, a cancer c...

A series of doxorubicin-loaded polymer-caged nanobins (PCN(DXR)) were evaluated in vivo in a murine MDA-MB-231 xenograft model of triple-negative breast cancer. The cross-linked polymer cage in PCN(DXR) offers protection for the drug payload while serving as a pH-responsive trigger that enhances drug release in the acidic environments commonly seen in solid tumors and endosomes. Varying the deg...
