Hepatocellular carcinoma (HCC) is a primary malignancy in the liver, which is a global health problem. The present study aimed to observe the apoptotic effects of berbamine on SMMC-7721 cell lines and to investigate the effects of berbamine on induction of the intrinsic apoptotic pathway. The human HCC SMMC-7721 cells were cultured and cell morphology observed using a phase contrast microscope....
Aminoglycoside antibiotics are widely used for the treatment of life-threatening bacterial infections, but cause permanent hearing loss in a substantial proportion of treated patients. The sensory hair cells of the inner ear are damaged following entry of these antibiotics via the mechano-electrical transducer (MET) channels located at the tips of the hair cell's stereocilia. d-Tubocurarine (dT...
Bcr-Abl tyrosine kinase inhibitors (TKIs) have been a remarkable success for the treatment of Ph(+) chronic myeloid leukemia (CML). However, a significant proportion of patients treated with TKIs develop resistance because of leukemia stem cells (LSCs) and T315I mutant Bcr-Abl. Here we describe the unknown activity of the natural product berbamine that efficiently eradicates LSCs and T315I muta...
Berbamine loaded chitosan-agarose microspheres were prepared using a water-in-oil emulsion technique. Optimum preparing parameters were determined by orthogonal experiments as follows: ratio of berbamine to chitosan (w/w) is 1:10; percentage of emulsifier (span 80, v/v) is 6%; volume of glutaraldehyde is 2 mL; and reaction temperature is 70 °C. Under these optimal conditions, the encapsulation ...
Liver cancer is the third leading cause of cancer deaths worldwide but no effective treatment toward liver cancer is available so far. Therefore, there is an unmet medical need to identify novel therapies to efficiently treat liver cancer and improve the prognosis of this disease. Here, we report that berbamine and one of its derivatives, bbd24, potently suppressed liver cancer cell proliferati...
Moderate to severe hearing loss affects 360 million people worldwide and most often results from damage to sensory hair cells. Hair cell damage can result from aging, genetic mutations, excess noise exposure, and certain medications including aminoglycoside antibiotics. Aminoglycosides are effective at treating infections associated with cystic fibrosis and other life-threatening conditions suc...
Pretreatment of berbamine protects the heart from ischemia/reperfusion (I/R) injury. However it is unknown whether it has cardioprotection when given at the onset of reperfusion (postconditioning (PoC)), a protocol with more clinical impact. Autophagy is upregulated in I/R myocardium and exacerbates cardiomyocyte death during reperfusion. However, it is unknown whether the autophagy during repe...
BACKGROUND Clinically, the patients with significant WBC decrease are mostly administered G-CSF, this kind of drugs is expensive and adverse reactions are often seen. In contrast, oral leucocyte increasing drug has small adverse reactions, can be used for longer time and can improve the continuity and stability of treatment. The experimental study based on study of mouse was to evaluate the eff...
The bisbenzylisoquinoline alkaloids aromoline and obamegine and the protoberberine alkaloid oxyberberine were isolated for the first time from the roots of Mahonia aquifolium (PURSH) NUTT. in addition to further two bisbenzylisoquinoline alkaloids berbamine and oxyacanthine, which have al ready been found in this species. Seeds of this plant contained the bisbenzyliso quinoline alkaloid isote...
Ca2+-stimulated Mg2+-dependent ATPase (Ca2+ + Mg2+-ATPase) stimulated by calmodulin, by partial proteolysis or by oleic acid in erythrocyte membranes was inhibited by various derivatives of the naturally occurring alkaloid berbamine. The ability of these derivatives to inhibit trypsin-activated Ca2+ + Mg2+-ATPase correlated well with their ability to inhibit the calmodulin-stimulated enzyme. In...
