Effect of green tea extract (Camellia sinensis) on the spermatic parameters of Wistar rats submitted or not to testicular heat shock
HS is shown to be widely deleterious to the gametes, and the daily administration of 100 mg/kg green tea extract does not improve the spermatic parameters of Wistar rats, submitted or not to testicular HS, although it leads to better recovery of sPermatic motility and morphology at 60 days. Expand

Green Tea Polyphenol Causes Differential Oxidative Environments in Tumor versus Normal Epithelial Cells
It is concluded that pathways activated by GTPPs or EGCG in normal epithelial versus tumor cells create different oxidative environments, favoring either normal cell survival or tumor cell destruction, which may lead to applications of naturally occurring polyphenols to enhance the effectiveness of chemo/radiation therapy to promote cancer cell death while protecting normal cells.
