We have synthesized graphene oxide (GO) nanosheets using modified Hummer's method and conjugated it with doxorubicin (DOx), an anticancer drug. Drug release kinetics from GO-DOx conjugate indicated the drug release at acidic pH. MTT assay performed on FaDu hypopharyngeal cancer cell lines revealed that the GO-DOx nanoconjugate inhibited cell proliferation more efficiently compared with pure DOx...

Intravesical instillation of antitumor agents following transurethral resection of bladder tumors is the standard strategy for the treatment of superficial bladder cancers. However, the efficacy of current intravesical instillation is limited partly due to the poor permeability of the urothelium. We therefore aimed to develop a high-penetrating, target-releasing drug delivery system to improve ...

Oxidative stress caused by doxorubicin (DOX) is believed to be a major underlying molecular mechanism of DOX-induced cardiotoxicity. Sesamin (Ses), an active component extracted from sesame seeds, exhibits antioxidative and anti-inflammatory effects. In the present study, possible protective mechanisms of Ses on DOX-induced cardiotoxicity were investigated in rats and cultured H9C2 cells. We de...

Doxycycline (Dox), a semisynthetic antibiotic, has been reported to exert multiple immunomodulatory effects. Treatment with Dox has a satisfactory curative effect against leptospirosis. In addition to its antibacterial action, we supposed that Dox also modulated immune response in controlling leptospira infection. Using J774A.1 mouse macrophages, the effects of Dox on protein and mRNA levels of...

To design a rapid release liposomal system for cancer therapy, a NIR responsive bubble-generating thermosensitive liposome (BTSL) system combined with photothermal agent (Cypate), doxorubicin (DOX), and NH4HCO3 was developed. Cypate/DOX-BTSL exhibited a good aqueous stability, photostability, and photothermal effect. In vitro release suggested that the amounts of DOX released from BTSL were obv...

The search for new macrofilaricidal drugs against onchocerciasis that can be administered in shorter regimens than required for doxycycline (DOX, 200mg/d given for 4-6 weeks), identified minocycline (MIN) with superior efficacy to DOX. Further reduction in the treatment regimen may be achieved with co-administration with standard anti-filarial drugs. Therefore a randomized, open-label, pilot tr...

Oxidative stress is one of the major factors in doxorubicin (DOX)-induced cardiomyopathy. Lectin-like oxidized low-density lipoprotein (oxLDL) receptor-1 (LOX-1) plays an important role to regulate cardiac remodeling and oxidative stress after ischemia-reperfusion. Therefore, we examined whether or not LOX-1 contributes to the pathogenesis of DOX-induced cardiomyopathy. Cardiomyopathy was induc...

We report in this study the complexation of the chemotherapeutic drug doxorubicin (DOX) with the novel sixth-generation cationic poly-l-lysine dendrimer (DM) (MW 8149 kDa), which we previously reported to exhibit systemic antiangiogenic activity in tumor-bearing mice. DOX-DM complexation was confirmed by florescence polarization measurement, proton nuclear magnetic resonance spectroscopy, and m...

Cardiotoxicity of doxorubicin (DOX) remains an important health concern. DOX cardiotoxicity is cumulative-dose-dependent and begins with the first dose of chemotherapy. No biomarker for presymptomatic detection of DOX cardiotoxicity has been validated. Our hypothesis is that peripheral blood cells (PBC) gene expression induced by the early doses of DOX-based chemotherapy could identify potentia...

objective(s):the colorectal cancer stem cells (cscs) with the cd133+ phenotype are a rare fraction of cancer cells with the ability of self-renewal, unlimited proliferation and resistance to treatment. quercetin has anticancer effects with the advantage of exhibiting low side effects. therefore, we evaluated the anticancer effects of quercetin and doxorubicin (dox) in ht29 cancer cells and its ...
