Stanford researchers make lung cancer finging that could vastly improve treatment and outcome
...iod. All patients with subtype 2 tumors were still alive at the end of the study. Garber said that tumors in subtypes 1 and 3 were initially diagnosed with different stages of the disease. Those in subtype 3 all had more advanced tumors while those in subtype 1 had less advanced tumors, consistent with th...More chance of a cure for patients with common and aggressive form of blood cancer

Thus, it is possible that we are detecting the residue of old untreated infections that are no longer transmissible or clinically significant.

...iple in the field of 'bioenergetics' *2. To stay alive organisms must be able to release energy in a controlled and useable form. Cells do this by converting metabolic energy derived from respiration into a compound called adenosine triphosphate (ATP).

Similar results were obtained after cultured Schwann cells were exposed to bacteria that had been killed with radiation and to fractions of the bacteriums cell wall.

...s overcome by cell death. Bcl-xL alone keeps cells alive but shuts down their growth. Only when you get the two together do you get this remarkable cooperation. The chances of two such mutations occurring together are very low, and this may be the fortunate reason that cancer cells arise so rarely in our b...Astrocytes play starring role in neural stem cell development

In other words, they might be merely supporting the cells in becoming functional neurons, Stevens said. "Another possibility was that the astrocytes were somehow actually instructing the stem cells to divide and a...Freezing cancer cells makes them prime targets for anti-cancer drug, new study finds

"There are 100-year-old whales alive today who can probably remember when the ocean was a much quieter place, and they could communicate with colleagues across grand expanses of ocean."

To keep the mice alive longer, the researchers also knocked out the gene for p53, which is an important component of the DNA damage detection system. "When we eliminated the p53 protein, the mice survived fine until after birth," said Alt. "However, after only a few weeks ...
