Introduction: Insulin-like growth factor-I (IGF-I) has a role in cell proliferation, differentiation, migration, and survival. By alternative splicing different IGF-I mRNA transcripts as IGF-IEc (mechano growth factor, MGF) or IGF-IEa variants are produced. MGF induces muscle hypertrophy and implicated in the pathophysiology of various types of cancer. Aim of the study was to investigate the role of MGF in the pathophysiology of neuroendocrine neoplasms (NENs).<p class="ab...

Introduction: Ephrin receptors (EPHs) have a role in tumor growth, invasion, angiogenesis and metastasis of several neoplasms. Aim of the study was to investigate the expression and possible clinical significance of EPH-A4 and EPH-A2 protein expression in the pathophysiology of neuroendocrine neoplasms (NENs).Methods: EPH-A4 and -A2 protein expression was assessed by immunohistochemical analysis along with Ki-67 proliferation index (%) on 28 paraffin emb...
