...organism (baker’s yeast) as well as in human small lung carcinoma cells. Their algorithm predicted, and subsequent experiments verified, that PTSB acted on thioredoxin and thioredoxin reductase, findings that not only validate the tool’s capability but could also pave the way to investigations of a poten...

Survey reveals women and doctors aren't talking about HPV

..., 59 percent believe either breast (30 percent) or lung (29 percent) cancer is most preventable. While there are risk factors associated with other cancers, only cervical cancer has a single known cause - HPV. # Only 23 percent of women surveyed correctly identified HPV as the primary cause of cervical ca...

New mitochondrial DNA gene chip may be early cancer diagnosis tool

...le early detection of some solid tumors, including lung cancer. Mitochondrial DNA (mtDNA) plays a role in respiration and the cell's energy conversion mechanism. Since the late 1990s, researchers at the Johns Hopkins University School of Medicine have observed changes in mtDNA sequences in solid cancers,...

Most common lung cancers may begin in newly discovered cells

The most common form of lung cancer may begin in a group of newly isolated lung stem cells, according to researchers from the Howard Hughes Medical Institute. Working in a mouse m...

Engineered molecule amplifies body's immune response

...een used, such as treatments for liver disease and lung fibrosis, as well as certain cancers. Improving Stat1 efficiency would allow for much lower doses of interferon to be used, decreasing cost and side effect profile. In terms of diagnosis, it may be possible to screen patients for the level of Stat1 r...
