Researchers reveal the new function of TERC on PD-L1 inhibition
SCIENCE CHINA PRESS IMAGE: TERC INHIBITS PD-L1 EXPRESSION AND AVOIDS CANCER IMMUNE ESCAPE CREDIT: ©SCIENCE CHINA PRESS TERC is a lncRNA with 451nt that functions as the template for telomerase during telomere lengthening. Several studies showed that TERC also functions as a lncRNA independent of telomerase, such as anti-apoptosis and regulates DNA damage response (Gazzaniga...

Study reveals how gastric cancer forms, suggests preventive treatment
by Vanderbilt University Graphical abstract. Credit: Gastroenterology (2022). DOI: 10.1053/j.gastro.2022.06.021 A recently published study reveals new insights into how gastric cancer develops and suggests a preventive treatment. Eunyoung Choi, Ph.D., assistant professor of Surgery, and colleagues identified for the first time that Trop2+/CD133+/CD166+ dysplastic stem cellsare a key source of clonal evolution of dysplasia to multiple types of gastric cancer. Their investigation further...

Most patients with appendicitis can be treated with antibiotics
UNIVERSITY OF CALIFORNIA – LOS ANGELES HEALTH SCIENCES FINDINGS Outpatient antibiotic management of selected patients with appendicitis is safe, allowing many patients to avoid surgery and hospitalization, and should be considered as part of shared decision-making between doctor and patient. Of 726 participants who were randomized to receive antibiotics, 46% were discharged from the emergency...
