"Growth arrest- specific gene 6 ( Gas6), identified in 1995, acts as the ligand to the Axl/ Tyro3 family of tyrosine kinase receptors and exerts mitogenic activity when bound to these receptors. Overexpression of the Axl/ Tyro3 receptor family has been found in breast, ovarian and lung tumours," researchers in Dublin, Ireland report. "Gas6 is upregulated 23- fold by progesterone acting through the progesterone receptor B ( PRB). Recently, Gas6 has been shown to be a target for overexpression and amplification in breast cancer. Quantitative real- time PCR analysis was used to determine the levels of Gas6 mRNA expression in 49 primary breast carcinomas. Expression of PRB...
