We have investigated the potential in vivo anti-tumour activity of corilagin using the Hep3B hepatocellular carcinoma cell line and an athymic nude mice xenograft model. The purity of corilagin was confirmed by high performance liquid chromatographic analysis. Corilagin was administrated intraperitoneally for a continuous period of 7 days at a concentration(More)
Esophageal squamous cell carcinoma (ESCC) has a high mortality rate and geographic differences in incidence. Previous studies of comparative genomic hybridization (CGH) showed that chromosomal 5p is frequently amplified in cell lines and primary ESCC of Hong Kong Chinese origin. In this report, attempt was made to study two novel genes, named as JS-1 and(More)
Recently we have shown the antiproliferative activity of Gleditsia sinensis fruit extract (GSE) on various solid tumour and leukaemia cell lines as well as primary cultured bone marrow cells isolated from patients with acute and chronic myelogenous leukaemia. We further studied whether the growth inhibitory effect of GSE involves basic fibroblast growth(More)
Hyperhomocysteinemia is an independent risk factor for atherosclerotic diseases. Inducible nitric oxide synthase (iNOS) is mainly expressed in macrophages upon stimulation. Overproduction of nitric oxide (NO) by iNOS can exacerbate the development of atherosclerosis. Our previous studies demonstrated that the extract of ginkgo biloba leaves (EGb) inhibited(More)
Blood supply plays a crucial role in solid tumour development and leukaemogenesis. It has been suggested that blocking of angiogenesis could be possible in cancer therapy. We have demonstrated the antiproliferative activity of Gleditsia sinensis fruit extract (GSE) on various human solid tumour cancer cell lines as well as leukaemia cell lines and primary(More)
Changes in the intracellular level of reactive oxygen species (ROS) including superoxide anion, hydroxyl radical, hydrogen peroxide and finally cellular acid-base equilibrium are reported to play an important role in the early step of apoptosis. All of which would precede the loss of mitochondrial membrane potential and releasing of those apoptotic inducing(More)
Nitric oxide (NO) is a potent vasodilator which plays an important role in regulating vascular tones. Danshen, a Chinese herbal medicine has been widely used for the treatment of cardiovascular diseases. The objective of this study was to investigate the effect of magnesium tanshinoate B (MTB), a compound purified from Danshen, on the production of NO in(More)
Recently, we have shown that the anomalous fruit extract of Gleditsia sinensis (GSE) processes apoptotic activity on numerous solid tumour and leukaemia cell lines as well as primary cultured leukaemia cells obtained from bone marrow aspirate of patients. GSE treated cancer cells exhibited apoptotic features as readily illustrated by morphological(More)
The anomalous fruit extract of Gleditsia sinensis (GSE) was shown to possess anticancer potential on various solid tumour and leukaemia cell lines in vitro. We have recently demonstrated that the mitochondrial-dependent apoptotic pathway including mitochondrial membrane potential depolarization, changes in the level of reactive oxygen species and activation(More)
Hyperlipidemia is a well-known risk factor for atherosclerosis and statins are widely used to treat patients with elevated levels of lipids in their plasma. Notwithstanding the proven benefits of statin drugs on both primary and secondary prevention of heart disease, the high cost of statin treatment, in addition to possible side effects such as liver(More)
