Twist is transcriptionally induced by activation of STAT3 and mediates STAT3 oncogenic function.

To explore the basis of metastasis, we compared the human breast cancer lines MCF-7 and MDA-MB453, which have low invasive ability, with their sublines MCF7-I4 and MDA-MB453-I4 with high invasive ability for gene expression and signaling pathways. We previously showed that the I4 lines had dramatically elevated levels of Twist compared with their parental lines. In this study, we observed significantly increased STAT3 Tyr(705) phosphorylation, but not the STAT3 protein levels, in the I4 lines.

[Amphibacillus haojiensis sp. nov.--a novel alkaliphilic and slight halophilic bacterium from Haoji Soda Lake in Inner Mongolia Autonomous Region, China].

An alkaliphilic and slightly halophilic Gram-positive rod, designated strain F10, was isolated from Haoji soda lake in Inner Mongolia Autonomous Region, China. Strain F10 grew optimally in the presence of 3% (W/V) NaCl, pH 9.5 and 37 degrees C.
