Abstract

White tea derived from the Camellia sinensis (L.) plant has anticancer effects. Its main catechin decreases the gene expression of Vegf in tumours. However, VEGF is also the angiogenic factor of the reproductive organs. In this study, Wistar rats were divided into the following groups (n=30): the control group (CT), which received water, and the white tea intake group (WT), for 3months. At the end of every month, the corpora lutea (CL) of ten rats were removed to evaluate the gene expression of Vegf and its receptors (Flt-1 and Kdr). White tea increased the relative mRNA abundance of Vegf (CT=0.95 +/- 0.06 and WT=2.13 +/- 0.19), Kdr (CT=0.88 +/- 0.06 and WT=1.94 +/- 0.32) and Flt-1 (CT=0.94 +/- 0.06 and WT=2.11 +/- 0.22) in CL (P<0.05). White tea increased angiogenic-related genes in rat CL but did not alter the number of rat CL. (AU)
