Live and let-7: MicroRNA plays surprising role in cell survival
Researchers at the University of California, San Diego School of Medicine have identified a microRNA molecule as a surprisingly crucial player in managing cell survival and growth. The findings, published in the Oct. 7 issue of Cell Metabolism, underscore the emerging recognition that non-coding RNAs -- small molecules that are not translated into working proteins -- help regulate basic cellular processes and may be key to developing new drugs and therapies.

Researchers find link between tobacco use and viral infection that causes oral cancers
Johns Hopkins scientists have shown a strong association between tobacco use or exposure and infection with oral human papillomavirus type 16, the sexually transmitted virus responsible for mouth and throat cancers worldwide. The numbers of such cancers have increased 225 percent in the United States over the past two decades.

Link between breast implants and cancer under investigation
An international research group including Viennese pathologist Lukas Kenner has reviewed cases of possible association between breast implants and a form of lymphoma that may develop tumors at a later stage. The researchers conclude that breast implants can cause a new subtype of the rare yet malignant lymphoma known as ALCL. The research results have been published in the journal Mutation Research.

'JAKing' up blood cancers, one cell at a time
A solitary cell containing a unique abnormality can result in certain types of blood cancers known as myeloproliferative neoplasms, according to researchers in Switzerland. The results open new opportunities to examine single mutant cells and follow tumor initiation and progression of human MPN cancers.

The skin cancer selfie
Melanoma is the fifth most common cancer type in the US, and it's also the deadliest form of skin cancer. If caught early enough though, it is almost always curable. The gigapixel camera, developed by a team at Duke University, is essential 34 microcameras in one and has a high enough resolution to zoom in to a tiny freckle making routine screenings available to a larger number of people at a fraction of the cost.

Stochastic variations of migration speed between cells in clonal populations
Microfluidic tools for precision measurements of cell migration speed reveal that migratory speed of individual cells changes stochastically from parent cells to their descendants, while the average speed of the cell population remains constant through successive generations. This finding is important in the context of cancer treatment, where treatments are sought to slow down the invasion of cancer cells.

A discovery could prevent the development of brain tumors in children
Scientists at the IRCM in Montréal discovered a mechanism that promotes the progression of medulloblastoma, the most common brain tumor found in children. The team, led by Frédéric Charron, Ph.D., found that a protein known as Sonic Hedgehog induces DNA damage, which causes the cancer to develop. This important breakthrough will be published in the Oct. 13 issue of the prestigious scientific journal Developmental Cell. The editors also selected the article to be featured on the journal's cover.
