Antitumor promoting activity of (−)‐epigallocatechin gallate, the main constituent of “Tannin” in green tea
Abstract
(−)‐Epigallocatechin gallate (EGCG) is the main polyphenolic constituent of extracts of green tea. EGCG slightly inhibited specific binding of [3 H] 12‐0‐tetradecanoylphorbol‐13‐acetate ([3 H]TPA) to a particulate fraction of mouse skin, and caused a prompt decrease in the phorbol ester receptor number in mouse skin. It also inhibited the activation of protein kinase C by teleocidin. In week 25 of a two‐stage carcinogenesis experiment in mouse skin, tumors were found in 53% of the mice treated with 7,12‐dimethylbenz(a)anthracene (DMBA) plus teleocidin, but in only 13% of those treated with DMBA plus teleocidin and EGCG. The average number of tumors per mouse in these groups was 2.1 and 0.1, respectively. No tumors were found in other groups treated with DMBA alone or teleocidin and EGCG alone. Thus EGCG inhibited tumor promotion by teleocidin.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
