human pituitary and prolactinoma

Analysis the different gene expression of prolactinomas and normal pituitary tissues. Prolactinoma is a benign pituitary tumor that produces excessive prolactin resulting in hyperprolactinemia and another disease.Tissues were microdissected and removed using the surgical microscope, rinsed in sterile saline, snap-frozen in liquid nitrogen, and stored (-80 ℃) until analysis. Results provide insight into understanding the difference of gene expression in prolacinomas. 5 prolactinoma and 4 normal pituitaries
