放射自显影研究显示，肿瘤细胞中大量掺入3H-前列腺素F2α 。

Experientia. 1980 Feb 15;36(2):246-7. doi: 10.1007/BF01953760.

A marked uptake (9-fold) of the 3H-PGF2 alpha was found specifically over heterochromatin in the nuclei of neoplastic cells. Lower but significant uptakes of 3H-PGF2 alpha were also found in the nuclei of control epidermal cells, which indicate the presence of nuclear receptors in the epidermal neoplastic cells.

在肿瘤细胞核内的异染色质上发现了3H-PGF2α的显著摄取（9倍）。在对照表皮细胞核中也发现了较低但显著的3H-PGF2α摄取，这表明表皮肿瘤细胞中存在核受体。
