Black tea and extracts play estrogenic activity via estrogen receptor α-dependent signaling pathway.

In recent years, phytoestrogens have been shown as useful selective estrogen receptor modulators. The estrogen-like effects of black tea (BT) and D. candidum (DC), as well as the combination of the two herbs, have remained largely elusive.

Erianin inhibits the proliferation of T47D cells by inhibiting cell cycles, inducing apoptosis and suppressing migration.

Erianin is a natural product extracted from Dendrobiumchrysotoxum. To investigate the antitumor activity of Erianin in estrogen receptor (ER) positive breast cancer, we treated T47D cells with Erianin and evaluated the effects of Erianin treatment on multiple cancer-associated pathways. Erianin inhibited the proliferation of T47D cells effectively.

GATA2 regulates GATA1 expression through LSD1-mediated histone modification.

The dynamic and reversed expression of GATA1 and GATA2 are essential for proper erythroid differentiation. Our previous work demonstrates that LSD1, a histone H3K4 demethylase, represses GATA2 expression at late stage of erythroid differentiation. K562 and MEL cells were used and cultured in Roswell Park Memorial Institute-1640 medium (RPMI) and Dulbecco's modified Eagle's medium (DMEM), respectively.
