Transcriptomic effects of medical treatment on gene expression of growth hormone secreting pituitary neruoendocrine tumour biology


ABSTRACT: Pituitary neuroendocrine tumours (PitNET) are rare neoplasms of the pituitary gland that can overproduce pituitary hormones or cause headaches and visual impairment due to mass effect. Growth hormone overproducing somatotroph PitNETs cause acromegaly leading to wide range of connective tissue, metabolic and oncologic disorders. The medical treamment of acromegaly is somatostin analogues (SSA) in specific cases combined with dopamine agnoists (DA), but almost half of patients excert SSA resistence and potential causes of this is unknown. The aim of this study was to characterize transcriptomic patterns of somatotroph PitNETs specifically assessing impact of SSA treatment effects. We investigated gene expession on several levels and functional models of GH PitNETs - tumour tissue of patients with and without SSA preoperative treamtment, tumour derived pituisphere model and classically used GH3 cell line treated with SSA.
