Tumors become highly malignant when they acquire the ability to colonize other tissues and form metastases. LMU researchers have identified a factor that promotes metastasis of colon tumors – and presents a possible target for therapy. The protein c-MYC is referred to as a master regulator because it controls the activity of hundreds of genes, including many that drive cell growth and cell proliferation. Genetic changes that perturb its own regulation therefore have serious consequences...

Australian scientists say altering the way cells express genes may give doctors a new way to combat malignant pleural mesothelioma. Raleigh, NC (PRWEB) October 28, 2013 In a study published in the Annals of Oncology and reported by Surviving Mesothelioma, researchers at the renowned Asbestos Diseases Research Institute in Sydney tested the role of microRNAs in mice with mesothelioma. MicroRNAs are tiny cell components responsible for the expression of a wide variety of genes, including...

3-way Genetic Switch Revealed For Cancer Metastasis

Rice University Cancer researchers from Rice University have deciphered the operating principles of a genetic switch that cancer cells use to decide when to metastasize and invade other parts of the body. The study found that the on-off switch's dynamics also allows a third choice that lies somewhere between "on" and "off." The extra setting both explains previously confusing experimental results and opens the door to new avenues of cancer treatment. The study appears online this week...

For the first time UFZ study describes the effects of prenatal environmental stressors on the regulation of microRNAs The Leipzig Helmholtz Center for Environmental Research has gained new insights on the influence of tobacco smoke in utero. For the first time, it could be demonstrated with smoking pregnant women and their children, how exposure to tobacco smoke affects the development of human immune system on molecular level. The focus thereby was on microRNA – a short, single-stranded...

  • The navel or umbilicus.
  • In Greek archaeology: A central boss, as on a shield, a bowl, etc.
  • A sacred stone in the temple of Apollo at Delphi, believed by the Greeks to mark the 'navel' or exact center-point of the earth.
'Omphalos' comes from the ancient Greek.
