Elevated cAMP levels in B-cell precursor acute lymphoblastic leukemia (BCP-ALL) cells attenuate the doxorubicin-induced p53 accumulation and protect cells against apoptosis. cAMP responsive element binding protein (CREB) is a cAMP-stimulated transcription factor that regulates genes whose deregulated expression cooperatein oncogenesis. In the present study, we investigated the role of CREB on i...

Objective: Physical activity and herbal medicine can inhabit apoptosis with two different mechanisms. The aim of this study was to assess the combined effect of regular aerobic exercise with garlic extract on heart apoptosis regulatory factors in aged rats with chronic kidney disease. Materials and Methods: In this experimental research, 42 aged male Wistar rats (48-52 weeks) were selected and...

       The protective effect of tomato extract and lycopene on acute doxorubicin-induced myocardial toxicity was evaluated in mice. Doxorubicin toxicity, induced by a single intraperitoneal injection (15 mg/kg), was revealed by elevated serum CPKMB and histopathological observations. Tomato extract (1.2 and 2.4 g/kg, i.p.) and lycopene (1.7 and 3.5 mg/kg, i.p.), prevented the rise in serum CPKM...

we investigated the vasodilatory effect of isoprenaline at large vessels (aorta, renal ans saphenous arteries, vena cava, renal and saphenous veins) in doxorbicin-induced model of heart failure. thirty saline-treated (normal group) and thirty doxorubicin treated rabbits (1 mg/kg administered intravenously twice weekly for 8 weeks) were studied after 16 weeks of treatment. chronic heart failure ...

objective(s) doxorubicin (dox), a widely used chemotherapeutic agent can give rise to serve cardiotoxicity by inducing apoptosis. curcumin, the active compound of the rhizome of curcuma longa l. has anti-inflammatory, antioxidant and anti-proliferative activities. curcumin has been identified to increase cytotoxicity in several cancer cell lines in combination with dox, but there is no study ab...

Attempts have been made to prepare nanoparticles based on poly(lactic-co-glycolic acid) (PLGA) and doxorubicin. Biological evaluation and physio-chemical characterizations were performed to elucidate the effects of initial drug loading and polymer composition on nanoparticle properties and its antitumor activity. PLGA nanoparticles were formulated by sonication method. Lactide/glycolide ratio ...

.a simple spectrofluorimetric method is described for the determination of doxorubicin (dxr) based on its quenching effect on the fluorescence intensity of tb 3+ - deferasirox (dfx) complex as a fluorescent probe. the excitation and emission wavelengths were 328 and 545 nm, respectively. the effects of ph, time, order of addition of reagents, concentrations of tb 3+ and dfx and the buffer volum...

Doxorubicin is cytotoxic anthracycline antibiotic drug used in cancer treatment. The drug’s efficacy various kinds of made its usage dominant for treating cancers. In this study, we determined the solubility doxorubicin three different polymers, i.e., poly (N-isopropyl acrylamide), polyethylene glycol, and polyvinyl pyrrolidone, to increase doxorubicin’s on targeted tumor site. We investigated ...
