17. Inhibition of mammary tumorigenesis in the C3(1)/SV40 mouse model by green tea.
Match Strength: 8.262
Previous studies show inhibitory effects of green tea in chemically induced mammary tumors or human tumor explants, but not in spontaneous tumor models that are more representative of human breast cancer. The C3(1)/SV40 mouse model is particularly suited for breast cancer prevention studies because it produces spontaneous ductal adenocarcinomas and a predictable time course for mammary tumorigenesis through a multistage progression similar to that occurring in humans. We therefore used this model to test the chemoprotective effects of green tea. Administration of 0.5% Polyphenon E (Poly E) (a ... Read More »

19. A comparison of the emission efficiency of four common green fluorescence dyes after internalization into cancer cells.
Match Strength: 8.202
In vivo optical imaging to enhance the detection of cancer during endoscopy or surgery requires a targeted fluorescent probe with high emission efficiency and high signal-to-background ratio. One strategy to accurately detect cancers is to have the fluorophore internalize within the cancer cells permitting nonbound fluorophores to be washed away or absorbed. The choice of fluorophores for this task must be carefully considered. For depth of penetration, near-infrared probes are ordinarily preferred but suffer from relatively low quantum efficiency. Although green fluorescent protein has been ... Read More »

43. Role of epigallocatechin gallate (EGCG) in the treatment of breast and prostate cancer.
Match Strength: 6.977
Green tea and its major constituent epigallocatechin gallate (EGCG) have been extensively studied as a potential treatment for a variety of diseases, including cancer. Epidemiological data have suggested that EGCG may provide protective effects against hormone related cancers, namely breast or prostate cancer. Extensive in vitro investigations using both hormone responsive and non-responsive cell lines have shown that EGCG induces apoptosis and alters the expression of cell cycle regulatory proteins that are critical for cell survival and apoptosis. This review will highlight the important in ... Read More »

45. Polyphenols from green tea and pomegranate for prevention of prostate cancer.
Match Strength: 6.923
Prostate cancer (PCa) is the most common non-cutaneous cancer diagnosed in North America with similar trends in many Western countries. Geographic, epidemiological and laboratory studies suggest a role for dietary constituents in the etiology as well as prevention of PCa. The rising incidence of PCa in several countries appears to be coincidental with adoption of western lifestyle. Increase in the incidence of PCa has also been found in Asian populations migrating to the west. These facts give numerous leads to explore testable PCa prevention strategies. There is growing evidence in support of ... Read More »

47. Green tea extract and (-)-epigallocatechin-3-gallate inhibit hypoxia- and serum-induced HIF-1alpha protein accumulation and VEGF expression in human cervical carcinoma and hepatoma cells.
Match Strength: 6.894
Green tea extract and its major component (-)-epigallocatechin-3-gallate (EGCG) exhibit antiangiogenic activities in various experimental tumor models. A growing body of evidence has established that hypoxia-inducible factor-1alpha (HIF-1alpha) and its downstream target, vascular endothelial growth factor (VEGF), play a critical role in tumor angiogenesis. In this study, we investigated the effect of green tea extract and EGCG on HIF-1alpha and VEGF expression in human cervical carcinoma (HeLa) and hepatoma (HepG2) cells. Our results showed that green tea extract and EGCG significantly ... Read More »
