Assessing the diagnostic, prognostic, and therapeutic potential of the somatostatin/cortistatin system in glioblastoma.

ABSTRACT: Glioblastoma remains an incurable tumour (median survival: ~ 15 months) and little clinical progress has been made over the past decades. Therefore, identification of novel biomarkers and therapeutic targets is imperative. Targeting the somatostatin/cortistatin-system is considered a successful avenue for treating different tumour pathologies. Thus, we comprehensively characterized (clinically and molecularly) the expression of the somatostatin/cortistatin-system components [ligands and receptors (SSTRs)] using five cohorts of patients and tested the in-vitro therapeutic response of different SSTR-agonists and somatostatin analogs (SSAs) in primary patient-derived glioblastoma cells. A clear downregulation of the whole somatostatin/cortistatin-system (except for SSTR5) in glioblastoma vs.
