Rhabdomyosarcoma (RMS) is the most common soft tissue sarcoma in children and adolescents and its occurrence in adults is extremely rare. There are three major subtypes of RMS of which alveolar RMS (ARMS) has the worst prognosis and tends to metastasize to unusual locations such as the pancreas. We present a case of a 19-year-old male with a rapidly enlarging right orbital mass, the imaging of which revealed it to be an infiltrative lesion with extension into the nasal cavity, ethmoid sinuses, and intracranial involvement. Histopathology confirmed the diagnosis of ARMS. A staging CT scan showed an enlarged and hypoenhancing pancreas; the histopathology test confirmed ARMS metastasis. It is important to consider pancreatic involvement in patients with ARMS, as it may be misinterpreted with other pathologies such as pancreatitis and pancreatic lymphoma. Metastasis to the pancreas can significantly alter the clinical approach and staging, underscoring the need for accurate diagnosis and staging in these patients.

The neuropeptide oxytocin (OXT) and its receptor (OXTR) have been shown to play an important role in glucose metabolism, and pancreatic islets express this ligand and receptor. In the current study, OXTR expression was identified in α-, β-, and δ-cells of the pancreatic islet by RNA hybridization, and OXT protein expression was observed only in β-cells. In order to examine the contribution of islet OXT/OXTR in glycemic control and islet β-cell heath, we developed a β-cell specific OXTR knock-out (β-KO) mouse.

Islet transplantation became a promising approach to replenish functional β-cell mass. However, not much known about changes in islets used for transplantation after isolation.

To better understand early human islet cell development and maturation, we collected 115 pediatric pancreata and mapped morphological and spatiotemporal changes from birth through the first ten years of life. Using quantitative analyses and a combination of complementary tissue imaging approaches, including confocal microscopy and whole-slide imaging, we developed an integrated model for endocrine cell formation and islet architecture, including endocrine cell type heterogeneity and abundance, endocrine cell proliferation, and islet vascularization and innervation.

Aims: Type 2 diabetes (T2D) is a prevalent metabolic disease linked to obesity and metabolic syndrome (MS). The glucolipotoxic environment (GLT) impacts tissues causing low-grade inflammation, insulin resistance and the gradual loss of pancreatic β-cell function, leading to hyperglycemia. We have previously shown that Compound A (CpdA), a plant-derived dissociative glucocorticoid receptor-modulator with inflammation-suppressive activity, displays protective effects on β-cells in type 1 diabetes murine models.
