Blood DNA Predicts Liver Cancer Early

...ists examined changes in certain tumour suppressor genes that have been associated with the development of liver carcinomas. The researchers studied the blood of patients enrolled in a cancer-screening programme in Taiwan who provided repeated blood samples prior to diagnosis. A total of 12,000 males and...

Liver Regeneration may Be Simpler Than Previously Thought

...es such as DNA microarrays – which determine which genes are active in a cells – and software programs that analyze the collected information, the scientists listed all the proteins that help the cells grow and proliferate in both samples. The results were unexpected. The researchers noticed that only ...

Environmental Factors Linked to Increased Risk of Breast Cancer

...pecific hypermethylation in a variety of different genes that might be important for breast cancer, according to Terry. Terry notes that although this pilot study used a very diverse sample, it was still a relatively small group, and the next step is a much larger study using samples from hundreds of ...

Gene Screening Points Way to More Effective Chemotherapy

...logy that can quickly screen all 20,000-plus human genes for biological activity, scientists have isolated 87 genes that seem to affect how sensitive human cancer cells are to certain chemotherapy drugs.// In a stu...

The Gen(i)e Behind Fatsos

...ucted by European researchers has shown that, //if genes called FTO portray mutation in both their copies, then such people stand a 70% chance of being over weight, as compared to people who possess normal copies of the gene. Researchers do not have the complete story yet. With a faint idea of what is ha...

Genes That Spread Breast Cancer Fast Identified

...r Center in New York say they have identified four genes that make breast cancer spread fast// and into the lungs. The four genes work together. Turning off all four genes at once dramatically reduces the ability of breast tumor...

Experimental Flu Vaccine Appears Promising in Early Tests

Drug Used to Prevent HIV Transmission from Mother to Child Damages DNA

... study found mutations in the K-ras and p53 cancer genes that are often mutated in human lung tumors. The development of lung cancer in these mice suggests that the incorporation of AZT or its metabolites into DNA, oxidative stress, and genomic instability may be the contributing factors to the pattern of ...
