A herbal complex consisting of Hoelen, Angelicae radix, Scutellariae radix and Glycyrrhizae radix suppressed cell viability and telomerase activity in hormone-refractory and chemo-resistant cancer cell lines, namely poorly differentiated uterine endometrial cancer cell line AN3 CA, adriamycin-resistant breast cancer cell line MCF7/ADR and cisplatin-resistant ovarian cancer cell line A2780. Furthermore, the herbal complex suppressed the expression of the full length of human telomerase reverse transcriptase (hTERT), which is related to telomerase activity. This indicates that the herbal complex can suppress the tumor growth of chemoendocrine resistant cancers, at least in part via suppression of telomerase activity associated with down-regulated hTERT.
Herbal complex (Hoelen, Angelicae Radix, Scuteltariae Radix and Glycycrrhizae Radix); Telomerase activity; AN3 CA; MCF7/ADR; A2780
