To obtain a better overview, the signal paths can be displayed by individual layers. The first tab in the bottom left of the signal path list shows all signal paths. If a label is shown under Extern, it overlays the primary label. In this case, it depends on the label ID that is transferred in the network. The column Mixer may contain a label that is specifically displayed on a mixer. The column Secondary shows the secondary label. The column Primary shows the primary label of each signal used on operating devices and UMDs (see UMDs). In the column Fam., each signal path's family is shown (see Signal Path Families). The column Info shows for each signal path whether it contains secondary functions or is linked to another signal. The abbreviations S and T stand for source and target, respectively. The column Moor indicates the position of each signal path on the physical layer. The column Layer shows on which phyiscal layer each signal lies (router, mixer, etc., see New Physical Layer). The column VM shows the location of each signal on a virtual layer (see New Virtual Layer). This name is created during the set-up of the signal path (see New Signal Path) and must be unique (across all routers) in the entire controlled system. It is also displayed as identifier (see Signal Path Name) in the master matrix (see Master Matrix). The list shows all existing signals and allows the set-up of new ones: The signal path name can be found in the column titled Signal Path Name. 'Our immediate goal is to explore and develop EphB2 chemical inhibitors and/or EphB2-targeting immune-cell based strategies, and to test their efficacy in preclinical esophageal as well as gastric cancer models, followed by transitioning to human trials,' said Guda.Open the signal path list by clicking on the appropriate button in the main menu bar: The scientists believe the EphB2 pathway is an attractive therapeutic target and suppressing its activity in cancer could be a beneficial treatment strategy for these cancers. This condition is linked to an increased risk of developing esophageal cancer, according to the National Institutes of Health (NIH). 'This is the first discovery to our knowledge that demonstrates EphB2 regulation of MYC and its physical interaction with MYCBP2.'īy analyzing normal, pre-cancer, and cancerous biopsy samples with RNA sequencing, the researchers found that EphB2 signaling is hyperactivated in nearly all instances of esophageal adenocarcinomas as well as a condition called Barrett's esophagus.īarrett's esophagus occurs when the lining of the esophagus becomes damaged by acid reflux, resulting in the replacement of esophageal cells with intestinal-type cells.

One mechanism by which EphB2 seems to affect MYC levels is through its direct interaction with a protein known as MYCBP2, which is a suppressor of MYC activity,' Guda said. 'From a molecular standpoint, EphB2 induces the levels of a well-recognized pro-cancer gene, called c-MYC. The findings also show that the EphB2 pathway appears to control the growth of cancer cells while also regulating the behavior of normal esophageal cells. New research published this month in Gastroenterology explains how an important molecular signal, known to scientists as the 'Ephrin B2 (EphB2) Tyrosine kinase pathway,' is activated during the development of esophageal adenocarcinomas and contributes to cancer growth. 'Like gastric and pancreatic cancers, these are highly aggressive malignancies that can be resistant to treatment, with dismal survival rates and with lack of effective targeted therapies.' 'The incidence of esophageal cancers has increased several fold over the last few decades, making it the most common esophageal malignancy in the U.S.,' said Kishore Guda, associate professor at the School of Medicine and member of the Case Comprehensive Cancer Center. Such dire data has long driven researchers to try to understand the roots of the disease, but they have discovered little-until now.Ī team of researchers at the Case Western Reserve University School of Medicine and Case Comprehensive Cancer Center believe they have identified a cell signaling pathway responsible for the development of esophageal adenocarcinomas, an aggressive form of esophageal cancer that has gradually become more common, even in younger people.
