By doing so,they remove the molecular(分子的)“tags” on cells that the immune system relies on to recognize cancer.(最近,科学家们发现,染色质蛋白,即组蛋白,有自己的编码,可以影响基因的控制。Wilfred Jefferies教授和他的同事们发现,一些癌细胞有能力改变这种“组蛋白密码”。通过这样做,他们去除了免疫...

For over a hundred years we’ve known that cancer cells prefer to break down sugar into lactic acid, but how they reprogram themselves has not been thoroughly studied. After their experimental studies, Børset and the research team figured out how cancer cells suddenly gain the ability ...
The research team found that cancer cells enhance a common mechanism in mammals and even yeast, which allows them to overcome glucose starvation. "We discovered that a protein called EBP4 regulates the rate at which the cell produces fat according to its energy status. When we observed the ...
“Cancer cells inside the body live in a complex environment or neighborhood. Where the tumor cell resides and who its neighbors are influenced its response and resistance to therapy,” said senior author Dr. Peter S. Nelson, a member of theHutchinson Cancer Center‘s Human Biology Division. ...
Scientists have discovered why cancer cells spread around a human body: They actually chase down healthy cells trying to escape. “Researchers are confident that some cancers work according to this chase-and-run principle,”io9.com reports. “Healthy cells try to escape from tumor cells, only ...
There may bevirushiding inside that cell. That cell could be mutating. It could be mutating and be benign, could be mutating and turning cancerous. It doesn’t matter – no smiley face. But see, the natural killer cells are, again, a very, very minute population. Now they may ramp up...
How are viruses detected? Virus: Many different types of infectious agents exist in the world, and the virus is one among them. They possess simple composition and exhibit small size. They possess the ability of multiplication only in living cells of plants, bacteria as well as animals. ...
Human cells have 23 pairs of each chromosome — half from the mother and half from the father, including the sex chromosomes X and Y — or 46 total. However, cancer cells are known to go through an intermediate state that has double that number – 92 chromosomes. How this happens was ...
