IGF1 represents an important growth factor in pituitary physiology and pathology, also mediating the negative feed-back mechanisms on somatotroph axis. It has been previously demonstrated that IGF1 promotes cell viability in primary cultures of human non functioning pituitary adenomas, by a mechanisms involving, at least in part, mTOR signaling, which is involved in many pathways controlling proliferation. We aimed at investigating whether mTOR may mediate IGF1 effects also in...
