Is the BRK tyrosine kinase expressed in high-grade serous carcinoma of the ovary?
The amplification of the BRK gene and overexpression of BRK protein in the majority of high-grade serous carcinomas and ovarian cancer cell lines suggest that BRK may play a role in the development and growth of ovarian tumors.
We suggest that repression of GA activity by KNOX transcription factors is a key component of meristem function. Transfer of the KNOX/GA regulatory module from the meristem to the leaf may have contributed to the generation of the diverse leaf morphologies observed in higher plants.
