High DIAPH1, EB1, KATNA1 and KIF14 protein levels were associated with increased overall survival (OAS) of ovarian cancer patients, while high DIAPH1 and EB1 protein levels were also associated with low differentiation of respective tumors (G2/3).
Herein, we show that the expression of end-binding protein 1 (EB1), a regulator of microtubule dynamics involved in multiple cellular activities, in breast tumor tissues correlates with the pathological response of tumors to paclitaxel-based chemotherapy.
In addition, EB1 could induce tumor formation in nude mice, activate beta-catenin-dependent gene expression and upregulate the transcriptional activity of c-myc.
The human EB1 gene product was recently found, by a yeast two-hybrid screening, to be associated with the carboxy terminus of the APC (adenomatous polyposis coli) protein, the product of a tumour-suppressor gene thought to act as a gatekeeper in colorectal carcinogenesis.
