Antibody Appears to Attack Cancer Cells, Leaving Other Cells Unscathed

The antibody works by targeting a natural defense mechanism that cancer tumors exploit. Cells in the body essentially use a home security system that relies on certain proteins to protect the cell surface and keep it safe. These proteins help the cell avoid injury and even death from unwanted activation of the immune system. In a paper published online May 5 in Cell Reports, the Duke team describes the workings of a cancer-fighting antibody they discovered, developed and tested in cell lines and animal models. The antibody dismantles a specific part of a cancer cell’s defense system and then employs several mechanisms of attack. "This is the first completely human-derived antibody developed as an anti-cancer therapy, which is very different from other immunotherapy approaches,” said senior author Edward F. Patz, Jr., M.D., the James and Alice Chen Professor of Radiology and professor in the Department of Pharmacology and Cancer Biology at Duke. Patz and colleagues -- including principals from the Duke Human Vaccine Institute who have been advancing the development of antibodies for an HIV vaccine -- started with the observation that some lun...

This study, published Wednesday in the International Journal of Cancer, was the first to pinpoint a specific temperature, according to the authors. Esophageal cancer is the eighth most common cancer in the world and is often fatal, killing approximately 400,000 people every year, according to the International Agency for Research on Cancer. It is usually caused by repeated injury to the esophagus due to smoke, alcohol, acid reflux and — maybe — hot liquids. The esophagus is a long tube through which swallowed food and liquids travel to reach the stomach. The American Cancer Society estimates that 13,750 new cas...

This study investigated the function and mechanism of PVT1 knockdown in the proliferation and malignant transformation of human gliomas. We firstly examined the expression levels of PVT1 and miR-424 in human glioma tissues and cell lines. We also used gene manipulation techniques to explore the effects of PVT1 knockdown on cell viability, migration, invasion, and miR-424. We found that PVT1 knockdown effectively inhibited cell viability, migration and invasion of human glioma cells and increased miR-424 expression. Based on the negative correlation between PVT1 and miR-424, we then confirmed the direct interaction between ...

Abstract In this paper, feruloylated bagasse xylan (FBX) was synthesized with a method based on homogeneous catalytic esterification of bagasse xylan (BX) with ferulic acid (FA) in the presence of triethylamine as a catalyst, and it was further grafted with methacrylic acid (MAA) and butyl acrylate (BA) to synthesize FBX-g-MAA/BA grafted copolymer by using ammonium persulfate as initiator and N,N-methylene acrylamide as cross-linker. The effects of reaction variables including reaction time, temperature and reactant concentration on the esterification and graft reactions were investigated carefully by conducting o...

The objective of this study was to investigate the prognostic significance of glycolysis-related proteins.Materials and methodsWe searched MEDLINE, EMBASE, Cochrane Database of Systematic Reviews, Cochrane Central Register of Controlled Trials, using Pubmed and Ovid as search engines and Google Scholar from inception to April 2017. Eighty-six studies with 12,002 patients were included in the study.ResultsOur pooled results identified that glycolysis-related proteins in cancers were associated with shorter overall survival of colorectal cancer (HR 2.33, 95% CI 1.38 –3.93,P = 0.002), gastric cancer (HR 1....

Younger women are having more heart attacks, and accounted for nearly a third of all female heart attack patients in recent years, according to a recent study. The news compounds a string of recent findings that have pointed to poorer overall health for young American women. “Women now, compared to younger women generations before them, are less healthy,” says study co-author Melissa Caughey, a cardiovascular epidemiologist and instructor at the University of North Carolina Chapel Hill School of Medicine. “It’s probably reflective of poorer health in general.” The study, which appeared in a sp...
