To improve the antitumor efficacy of doxorubicin (DOX) and provide novel clinical treatment of gastric cancer, halloysite nanotubes (HNTs) loaded with DOX were encapsulated by soybean phospholipid (LIP) and the formed HNTs/DOX/LIP was systematically characterized via different techniques. The in vitro anticancer activity of HNTs/DOX/LIP was examined using an MTT assay. The antitumor efficacy an...

Resistance to treatment with anticancer drugs is a significant obstacle and a fundamental cause of therapeutic failure in cancer therapy. Functional doxorubicin (DOX) nanoparticles for targeted delivery of the classical cytotoxic anticancer drug DOX to tumor cells, using folate-terminated polyrotaxanes along with dequalinium, have been developed and proven to overcome this resistance due to sp...

Doxorubicin (DOX) is an anticancer drug used for the treatment of solid tumors. The ability of DOX to treat cancer is not specific to cancer cells; some of the cells that are normal may also become targets of DOX, thereby altering the normal cellular functions and eventual cell loss. DOX effects have been studied in detail in heart because of its ability to cause cardiomyopathy. The exact mecha...

The anticarcinoma antibody BR64 was conjugated to a doxorubicin derivative, doxorubicin 13-[3-(2-pyridyldithio)propionyl]hydrazone, and the resulting conjugates (BR64-DOX) were evaluated for activity and immunological specificity in vitro and in human tumor xenograft models. The BR64-DOX immunoconjugates retained immunoreactivity and cytotoxicity and demonstrated antigen-specific cytotoxicity i...

We investigated the potential for additive therapy for malignancy using an anti-human T-cell monoclonal antibody, T101, and the chemotherapy agent doxorubicin (DOX). We compared the efficacy of T101 alone, DOX alone, T101 and DOX covalently linked to dextran to form an immunoconjugate, T101 plus DOX mixed together and injected, T101 and DOX injected separately, and nonspecific murine IgG2A plus...

PURPOSE Anti-HER2 immunoliposomes combine the tumor-targeting of certain anti-HER2 monoclonal antibodies (MAbs) with the pharmacokinetic and drug delivery capabilities of sterically stabilized liposomes. We previously showed that anti-HER2 immunoliposomes bind efficiently to and internalize in HER2-overexpressing cells in vitro, resulting in intracellular drug delivery. EXPERIMENTAL DESIGN He...

A combination of magnetic hyperthermia and magnetothermally-facilitated drug release system was developed as a promising strategy for liver cancer therapy. The thermosensitive copolymer, 6sPCL-b-P(MEO2MA-co-OEGMA) shows a good temperature-controlled drug release response. Mn-Zn ferrite magnetic nanoparticles (MZF-MNPs) exhibit a strong magnetic thermal effect with an alternating magnetic field ...

Although the serious cardiotoxicity of doxorubicin (DOX), a useful chemotherapeutic agent, limits the use of this agent, the mechanism of DOX-induced cardiomyopathy remains unclear. Since accumulating evidence suggests that activation of the renin-angiotensin system is involved in the development of various types of cardiovascular remodeling, we examined the role of angiotensin II (Ang II) in D...

Doxorubicin (DOX) is one of the most frequently used anti-cancer drugs and the front line option for hepatocellular carcinoma (HCC) treatment. However, the clinical applications of DOX are restricted largely due to its toxicity and chemoresistance. Here, we report that miR-375 and DOX were co-delivered by liposomes (named L-miR-375/DOX-NPs) for combination therapy of HCC and drug resistance rev...

Doxorubicin (DOX) is an effective antitumor agent used in cancer treatment. However, its clinical use is limited due to cardiotoxicity. Indeed, the side effects of DOX are irreversible and include the development of cardiomyopathy and ultimately congestive heart failure. Although many studies have investigated the events leading to DOX-induced cardiotoxicity, the mechanisms responsible for DOX-...
