Xiaoyen Zheng, Ph.D., will begin her latest research to understand the mechanisms behind the Hedgehog receptor in May 2017 WASHINGTON (May 4, 2017)-- Among scientists specializing in the area, the mechanisms behind the signaling function of the Hedgehog (Hh) receptor pathway remain a mystery. Xiaoyen Zheng, Ph.D., assistant professor of anatomy and regenerative biology at the George Washington University (GW) School of Medicine and Health Sciences (SMHS), who recently received a $1.7 million grant from the National Institutes of Health and National Institute of General Medical Sciences, is determined to learn more about the Hh pathway. With this funding, Zheng will develop a comprehensive understanding of the pathway's underlying mechanisms. Previous research has shown that the Hh receptor, Patched, regulates pathway activity. Studies have also shown that Hh pathway components are trafficked through the cilium of cells. This led Zheng to look at the possibility of ciliary trafficking as a crucial regulation point for the Patched component. The focus of her research is to look at the primary cilium's role as the cellular platform for the process. Over the course of the study, Zheng and her team will employ the use of both cell lines and mouse models. "A comprehensive understanding of the signal transduction will provide a better basis for the design and implementation of effective therapeutic approaches to diseases caused by malfunction of the Hh signaling pathway," Zheng said. The Hedgehog receptor plays an important role in embryonic development and adult stem cell function. A loss of signaling during development can result in birth defects, such as holoprosencephaly and congenital heart disease. Post-development loss is associated with a variety of cancer types. Zheng received seed funding from the GW School of Medicine and Health Sciences and from GW Cancer Center to begin her research. Her mentors and colleagues at SMHS also provided feedback during the proposal process. Zheng also gives credit to Peter Nemes, Ph.D., assistant professor of chemistry at the GW Columbian College of Arts and Sciences, who has collaborated on the proposed research. The project, titled "The Role of Ciliary Trafficking in Hedgehog Receptor Function" will be funded for a five-year period.

LEXINGTON, Mass., Nov. 28, 2016 (GLOBE NEWSWIRE) -- Curis, Inc. (Nasdaq:CRIS), a biotechnology company focused on the development and commercialization of innovative and effective drug candidates for the treatment of cancer, today announced that the European Medicines Agency’s (EMA) Committee for Medicinal Products for Human Use (CHMP) has granted full approval to Erivedge® (vismodegib) for the treatment of adult patients with symptomatic metastatic basal cell carcinoma (BCC) or locally advanced BCC inappropriate for surgery or radiotherapy. Erivedge is also approved in the U.S. for the treatment of adults with metastatic basal cell carcinoma, or with locally advanced basal cell carcinoma that has recurred following surgery or who are not candidates for surgery, and who are not candidates for radiation. Erivedge was developed and is marketed by Roche and Genentech, a member of the Roche Group, under a collaboration agreement between Curis and Genentech. Erivedge was originally granted ‘conditional approval’ in July, 2013 in the European Union (EU) and the authorization has now been converted from ‘conditional’ to ‘full approval’ based on the results from the STEVIE study that included 1215 patients with advanced BCC. STEVIE (MO25616) is a single-arm, open-label, Phase II, multicenter study that was conducted by Roche to assess the safety of vismodegib in patients with locally advanced and metastatic BCC. The safety and efficacy results of the STEVIE trial were consistent with the results of the pivotal study ERIVANCE BCC (SHH4476g) that supported the initial conditional approval of the drug in the EU. About Basal Cell Carcinoma and the Hedgehog Pathway According to the American Cancer Society, BCC accounts for approximately 80 percent of all diagnosed skin cancers. The disease is generally considered curable if the cancer is restricted to a small area of the skin. However, in a small group of people, if the disease is left untreated or recurs in the same location after surgery or radiotherapy, it may become locally advanced and invade further into surrounding areas such as sensory organs (ears, nose and eyes), bone, or other tissues. Depending on the location of the lesion, some cases of advanced BCC can be disfiguring, and treatment with surgery or radiation can lead to the loss of sensory organs and their functions such as eyesight or hearing. In a small proportion of patients, BCC can metastasize, spreading to other parts of the body. Abnormal signaling in the Hedgehog pathway is implicated in more than 90 percent of BCC cases. Erivedge is designed to selectively inhibit signaling in the Hedgehog pathway by binding to a protein called Smoothened. The Hedgehog signaling pathway plays an important role in regulating proper growth and development in the early stages of life and normally becomes less active in adults. The Hedgehog signaling pathway is implicated in the development of certain types of cancer, including BCC. In January 2012, Erivedge became the first licensed medicine for patients with advanced basal cell carcinoma when the U.S. Food and Drug Administration (FDA) approved it under the priority review program that provides for an expedited six-month review of drugs that offer major advances in treatment. Erivedge is approved in the U.S. for the treatment of adults with metastatic basal cell carcinoma, or with locally advanced basal cell carcinoma that has recurred following surgery or who are not candidates for surgery, and who are not candidates for radiation. Erivedge is currently approved and marketed in multiple countries worldwide. Erivedge is currently in development by Roche and Genentech in other diseases including idiopathic pulmonary fibrosis and myelofibrosis. Under the ongoing collaboration agreement between Genentech, a wholly owned member of the Roche Group, and Curis, Erivedge (vismodegib, GDC-0449, RG3616) was discovered by Genentech and was jointly validated by the parties through a series of preclinical studies. Pursuant to this collaboration, Genentech and Roche are responsible for clinical development, and Genentech (U.S.), Roche (Ex-U.S. excluding Japan) and Chugai Pharmaceuticals (Japan) are responsible for commercialization of Erivedge. Curis receives royalties on sales of Erivedge by Genentech/Roche. About Curis, Inc.

This paper presents and demonstrates a method to quickly identify when regular periodic activities, such as a daily night setback on a thermostat, are inappropriately configured or accidentally reset. Anomalies in periodic building operations are identified by analyzing smart meter electrical demand data in the frequency domain with a weekly travelling time window instead of using time domain functions such as load factor. Initial experiments on a real site found that spectral energy signals for periodic (frequency) hours of 4, 6, 8, 12 and days 1, 3.5 and 7 to be greatly reduced when a device is not functioning appropriately. In addition, the ratio of the DC offset (0 Hz) energy with the other higher periodic energies can normalize the periodic energies to a relative index that can then be used for comparing other seasons and other buildings for periodical performance. © 2012 IEEE.

When evaluating the risk of a data or system security breach, it's essential that one addresses the consequences in a comprehensive way. One of the most significant threats is the devaluation of the business itself and the impact on the company's reputation. The data breach or technical compromise is actually only the mechanism through which the threat is realised. © 2013 Elsevier Ltd.
