Much previous research looking at the precise ways in which alcohol causes cancer has been done in cell cultures. But in this study, researchers have used mice to show how alcohol exposure leads to permanent genetic damage. Scientists at the MRC Laboratory of Molecular Biology, Cambridge, gave diluted alcohol, chemically known
Cells produce several alternative isoforms of Numb by differentially processing, or splicing, the mRNA encoding Numb to include or exclude specific regions of the protein. How this alternative splicing affects Numb's various functions remains unclear. In mammary gland stem cells, for example, Numb binds and inhibits an enzyme called Mdm2, preventing
The screening technology, developed by Howard Hughes Medical Institute Investigator (HHMI) Christopher Garcia and colleagues after almost 20 years of basic molecular studies of the immune system, may ultimately lead to more effective immunotherapies, which harness the body's immune system to fight cancer. "This is going to widen the scope
Using a process known as single-cell RNA-sequencing, the researchers analyzed more than 6,000 individual cells from head and neck squamous cell carcinomas -- the most common head and neck tumor. Through their analysis, the research team created an atlas of all the different cells present in head and neck cancer.
The study focused on a gene called AMIGO2 and its partner, called PTK7. Scientists' understanding of AMIGO2's role in cancer has been limited until now, but the researchers discovered that AMIGO2 and PTK7 is required for melanoma cells to grow and survive. This research also identified a path forward to develop
In a study led by Dipanjan Pan, an Illinois professor of bioengineering, researchers designed nanoparticles that specifically bind to a protein that marks the surface of breast cancer stem cells. Encapsulated in the particles is the drug niclosamide -- a drug commonly prescribed around the world to treat tapeworm infections,
But researchers have recently used T-cells engineered in the laboratory to combat tumours. Modified to include additional functions, these immune cells can hunt down and kill cancer cells. Unfortunately, however, such immune cell therapies can have significant side-effects. On top of that, the production of modified T-cells is technically challenging.
"Breast tumors are moving targets because they are really versatile," says Jun-Lin Guan, Francis Brunning Professor and Chair of the Department of Cancer at the University of Cincinnati College of Medicine and member of the Cincinnati Cancer Center and UC Cancer Institute, who co-authored the paper with postdoctoral fellow Syn
