In contrast to standard therapies for heart failure, JQ1 works directly within the cell’s command center, or nucleus, to prevent damaging stress responses. This groundbreaking research lays the foundation for an entirely new way of treating a diseased heart…
In the journal Cell Reports, published today online, the scientists describe how the powerful master regulatory transcription factor Bcl6 regulates the genome, ensuring that aggressive lymphomas survive and thrive. They also show how the Bcl6 inhibitor, developed at Weill Cornell, effectively gums up the protein, stopping it from working…
The researchers’ study, published in today’s issue of the journal Nature, found that an enzyme, activation-induced cytidine deaminase (AID), helps in the process that changes an adult human cell into an induced pluripotent stem cell (iPS cell). …
"I think that most organic chemists had considered ingenol beyond the reach of scalable chemical synthesis," said TSRI Professor Phil S. Baran. Baran and his laboratory report their achievement in this week’s issue of Science Express, the early online edition of the journal Science…
Some people develop invasive bladder cancer, which is where the cancer has grown through the muscle layer of the bladder. When this occurs, there is a higher risk that the cancer will spread to other areas of the body and it is much more difficult to treat…
The identification of CPTP was the result of an international collaboration that built on prior research by co-lead author Charles Chalfant, Ph.D., Endowed Chair of Cancer Cell Signaling and member of the Cancer Cell Signaling program at Virginia Commonwealth University Massey Cancer Center as well as professor in the Department of Biochemistry and Molecular Biology at VCU School of Medicine. The team discovered that CPTP regulates levels of biologically active lipids, which are molecules such as fatty acids that often play a role in cell signaling…
However, if the patient’s gastrointestinal tract remains healthy and functioning, the patient’s chances of survival increase exponentially, said Jian-Guo Geng, associate professor at the University of Michigan School of Dentistry. Recently, Geng’s lab discovered a biological mechanism that preserves the gastrointestinal tracts in mice who were delivered lethal doses of chemotherapy. …
The finding offers the potential that these stem cells could somehow be turned back on, offering a new form of treatment for the condition, called Acute Myeloid Leukemia (AML). The work was led by scientists at Queen Mary, University of London with the support of Cancer Research UK’s London Research Institute…
In addition to causing cervical, anal and genital cancers, HPV has more recently been found to cause some head and neck cancers. "One of the main issues is this form of esophageal cancer is usually diagnosed quite late and so has a very high mortality," says the first author of the paper, Dr Surabhi Liyanage, a PhD candidate with the School of Public Health and Community Medicine, UNSW Medicine…
"We split the samples into two groups: poor responders who had gone less than 100 days after treatment before the progression of their disease, and strong responders who had made it more than 300 days after their treatment without disease progression. Then we could explore the genetic differences between these two groups," says Dawn Duval, PhD, CU Cancer Center investigator and associate professor of molecular oncology at Colorado State University. Specifically, Duval and colleagues including first author Deanna Dailey, DVM, looked at the expression of a protein called HES1, which is used as a proxy to test for NOTCH activation. High HES1 means that upstream, NOTCH is firing…
