PMID: 22782554
The tumorigenesis of pituitary adenomas is poorly understood. Mutations of the PIK3CA proto-oncogene, which encodes the p110-α catalytic subunit of PI3K, have been reported in various types of human cancers...

PMID: 21270509
Background: Pituitary tumors account for approximately 10-15% of intracranial neoplasms. Aim: Using the cDNA microarray method, we have previously compared expression under two distinct conditions: a pool of 4 clinically...

42(9):791-5.
PMID: 19738985
Amplification of the MYCN gene in neuroblastomas is a potent biological marker of highly aggressive tumors, which are invariably fatal unless sound clinical management is applied. To determine the usefulness...

20(9):1052-7.
PMID: 18624930
The neurotensin (NT) produced in the hypothalamus and in pituitary gonadotrophs and thyrotrophs participates in neuroendocrine regulation. Recently, the involvement of this peptide in normal and neoplastic cell proliferation has...
