Proteomics and transcriptomics analyses of secretagogin down-regulation in human non-functional pituitary adenomas.

abstract：PURPOSE:Hypofractionated stereotactic radiotherapy (HSRT) for refractory Cushing's disease may offer a condensed treatment schedule for patients with large tumors abutting the optic chiasm unsuitable for stereotactic radiosurgery (SRS). To-date only four patients have been treated by HSRT in the published literature. W...
