Building a better mouse model of lung cancer: FHIT counts

... neck, esophageal, colorectal, breast and cervical cancers as well. Because the loss of FHIT occurs so early in lung cancer, mice that are missing that gene may be a good model in which to test new ways to treat or prevent the disease, says Huebner. "There are some other useful mouse models out there, but t...

Customized gene chip provides rapid detection of genetic changes in children's cancer

...rect risk level allows doctors to treat aggressive cancers appropriately, while not subjecting children with low-risk cancer to overtreatment. Cancer researchers have pinpointed specific genetic abnormalities that influence the aggressiveness of neuroblastoma. An important abnormality is loss of heterozygos...

Researcher uncovers details of how cancer spreads

... v-Src in human cancer patients, a number of other cancers have been linked to viruses, including the herpes virus and its association with cervical cancer. "Critics of this work will ask why v-Src has not been found in human cancer," said Guan. "But there are many examples of studies and ideas that come ou...

Study hints at role of stem cell genes in testicular, breast cancers

Scientists closer to new cancer detection method

... to a technique to easily detect a wide variety of cancers before symptoms become apparent. The findings, currently online in the Proceedings of the National Academy of Sciences, involve introducing molecularly engineered strands of DNA into cell cultures and observing whether they unleash a fluorescent bur...

Biologists Crack Genetic Code for Specialized Spider Silk

Furthermore, IgA deficiency and CVID can predispose to autoimmune diseases, where the immune system turns against the body’s own tissues and organs. “Most cases of CVID and IgA deficiency are of un...

Defective Gene Linked to Two Inherited Immune Deficiencies

A 'dimmer switch' for genes

...tion between factors such as Ets-1 and a number of cancers prompted the study of how it works. One way proteins are controlled occurs after a cell creates a protein. Graves illustrates this process by comparing protein structure with beads on a string. "After the protein is made, it can acquire what we call...

As predicted, when the virus was injected directly into the primary tumor, the virus destroyed not only the primary tumor, but also distant tumors. While the infection caused by the virus was ...
