Pituitary adenomas (PA) are benign tumors that develop in pituitary gland. Hormone secreting PA can cause overproduction of pituitary hormones leading to different systemic endocrine disorders (acromegaly, Cushing’s disease and others). Non-secreting PA can promote headaches (stretching of the dural sheath) and visual field defects (chiasma compression). We managed to obtain resected tumor samples from the patient having non-secreting PA, first tumor was resected in 2010,...

Pituitary neuroendocrine tumors (PitNETs) are non-metastatic neoplasms of the pituitary that may overproduce hormones leading to systemic disorders or tumor mass effects causing headache, vertigo, or visual impairment. The overall estimated clinical prevalence of PitNETs is 1 in 400 to 1 in 1000 people. Although the pathogenesis of PitNETs has been extensively studied the molecular factors underlying tumorigenesis, remission, and therapy response of PitNETs are still unclear. ...

Neuroendocrine neoplasms (NENs) are a highly heterogeneous group of tumors that arise from the diffuse neuroendocrine system and whose incidence has increased over the last years. Among them, pancreatic NENs (PanNENs) are relatively common and one of the most studied NENs. PanNENs are characterized by a low number of mutations, with some genes frequently mutated, such as MEN1, ATRX/DAXX, and mTOR signaling pathway genes. Despite genomics, transcripto...

Introduction: Pituitary adenomas (PA) are tumours of the anterior pituitary. Despite the benign nature these neoplasms cause increased mortality and morbidity. Clinically relevant PAs affect around 0.1% of population during their lifetime. Currently, there is no human PA cell culture models. Tissue cultures derived from PA surgery materials depending on harvesting conditions can form free floating aggregates called pituispheres (PS) or adherent mesenchymal stromal cells (MSC)....
