Neuroendocrine tumors (NETs) are uncommon neoplasms with increasing incidence and limited therapeutic options, wherein identification of new diagnostic/prognostic/therapeutic biomarkers is urgently required. Alterations in somatostatin (SST)/cortistatin (CORT) and ghrelin systems have been associated to development/progression of several cancers. Thus, we evaluated expression levels of SST/CORT/ghrelin system components in gastroenteropancreatic-neuroendocrine tumors (GEP-NETs...

Introduction: The analysis of the signaling pathways involved in vascular calcification is difficult due largely to the limitation in obtaining vascular tissue samples. Therefore, the use of bioinformatics tools for the identification of potential biomarkers associated with vascular calcification is an advantage for the advancement in the knowledge of the molecular pathways involved in this pathology.Objective: Increase understanding of the molecular mec...

Introduction: Trabecular Bone Score (TBS) is a new non-invasive method to evaluate trabecular bone quality at the lumbar spine. The literature has contradictory results concerning the influence of insulin resistance and adipose tissue on bone, for this reason it is of interest to evaluate factors that determine bone health and risk of fracture in patients with T2DM.Objective: To analyze the relationship between insulin resistance and adipose tissue with ...

Introduction: Sclerostin is a glycoprotein expressed mainly by osteocytes, which acts as inhibitor of bone formation. However, several studies have shown an increase in serum levels of sclerostin in subjects with type 2 diabetes (T2D) and cardiovascular disease (CVD) suggesting an additional role of this protein at the vascular level. The hypothesis that sclerostin could be expressed by vascular smooth muscle cells (VSMCs) under calcifying conditions could justify this elevati...

Introduction: Emerging evidence indicates that dysregulation of alternative splicing represents a new hallmark of cancer. This dysregulation may arise from mutations or altered expression of specific components of the splicing machinery. To date, splicing machinery status has not been studied in lung neuroendocrine neoplasms: typical and atypical pulmonary carcinoids.Objectives: Here, we aimed to analyzing the splicing machinery in pulmonary carcinoids a...
