The cytoplasmic pattern of ephrin A4 could identify a subgroup of primary osteosarcoma patients with a high liability for progression, poor prognosis, and inferior response to chemotherapy.
Acne is a longstanding inflammatory disease of the pilosebaceous unit resulting from androgen-induced increased sebum production, altered keratinization, inflammation, and bacterial colonization of hair follicles by Propionibacterium acne [1]. Apelin is a newely discovered adipocytokine secreted by white adipose tissue and couples with the APJ receptor with the highest affinity. Apelin and the APJ receptor are found in pancreatic islet cells and found to have a role in energy metabolism. Many researches show that apelin has a role in glucose homeostasis regulation, insulin secretion, and increasing insulin sensitivity [2].The aim of the work was to evaluate the serum level of Apelin-13 in patients with acne vulgaris .Serum apelin was measured in 40 patients with moderate to severe acne vulgaris and 30 healthy controls using enzyme-linked immunosorbent assay (ELISA). Serum levels of apelin13 in patients with acne vulgaris was found to be higher than in healthy controls (p value <0.005).In Conclusion Serum apelin13 has a role in the pathophysiology of acne vulgaris patients.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
