New tumor-suppressor gene discovered

...The team's genetic and biochemical studies will be published in the 11 March 2005 issue of the journal Cell. "This discovery extends our understanding of how tissue growth is controlled both during normal development and during the formation of tumors, and it raises the possibility that the function of this ge...

Biomarkers isolated from saliva successfully predict oral and breast cancer

...ne out of 10 cases. A recent study by this group, published in Clinical Cancer Research, disclosed similar predictive powers for head and neck cancers. "These results indicate that such biomarkers found in saliva, called salivary transcriptomes, can be exploited for robust, high-throughput and reproducible t...

Cooperation is key—a new way of looking at MicroRNA and how it controls gene expression

... identified. When the human genome was solved and published in 2001, many scientists thought that the task of finding the mRNA to which the microRNA bound would be relatively straightforward. After all, a short stretch of nucleotides like a microRNA should be expected to bind to a piece of RNA of equal length...

Insight into DNA's 'weakest links' may yield clues to cancer biology

...ks that might help to explain them. The findings, published in the March 11, 2005, issue of Cell, suggest that yeast may offer a useful model system for studying the fundamental properties of so-called DNA fragile sites, providing new insight into the chromosomal instability found in cancer cells, said the re...

The groundbreaking research published in Nature Genetics last week, provides a roadmap for the development of human therapies for CMV, which could prolong the life of HIV patients and improve the success of transplant surgery by reducing the risk of rejection. There is currently no treat...

New World founders small in number

...ends and the details are hotly debated. In a paper published in the premier open-access journal PLoS Biology, Jody Hey now reveals how the sizes of the first New World populations have changed since they were founded. His new approach shows that the New World was colonized by a surprisingly small population wi...

The research, published in the April issue of Cancer Cell, is likely to facilitate development of new strategies to combat drug resistance and treatment failure for children with ALL. Nearly 80% of children with ALL are cured following chemotherapeutic treatment. However, ...

Protein Discovery Could Unlock The Secret To Better TB Treatment

...cts around 10 to 15 people every year. In a study published on 1st March 2005 in Nature Structural & Molecular Biology, a combined team discovered the structure of a protein known as resuscitation promoting factor (Rpf). Five versions of the Rpf protein exist in TB bacteria. The paper's unveiling of the m...
