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...

Cancer cells love sugar too. This characteristic is used in one of the common methods for diagnosing cancer metastases through PET CT scans, during which radioactive sugar is injected into the patient. Because cancerous tumors feed on sugar, the radioactive sugar accumulates in the tumor, making...
How regular cells are similar to cancer cells?Cells:Cells are the smallest unit of life. Cells can be eukaryotic, meaning they possess true nuclei and membrane-enclosed organelles. They can also be prokaryotic, meaning they lack both of these features and only have a nucleus-like region called...
cancer stem cell tumorigenesis is CSCs,which,by dividing cells,produce the same daughter cells and differentiate into different types and can create tumor tissue from a single cell.They are responsible for the development of cancer,progression,metastasis,recurrence,and treatment resistance,and are ...
However, stem cells and some cancer cells make enough telomerase to keep their telomeres from shortening, effectively stopping the aging clock and allowing a seemingly unlimited number of cell divisions. Mutations that block telomerase activity cause cirrhosis in mice and humans and conversely, mutations...
The bioengineered immune players called CAR T cells last longer and work better if pumped up with a large dose of a protein that makes them resemble stem cells. By Sara Reardon A CAR T cell (orange; artificially coloured) attacks a cancer cell (green). Credit: Eye Of Science/SPL ...
For example, if the guide RNA matches a gene that suppresses tumor growth, there is a risk that disabling it could turn the cell cancerous. Another issue is that CRISPR editing is not 100% efficient, so only a proportion of the targeted cells undergo the desired genetic change. This means...
your immune system may become compromised. This means that your body may have a harder time fighting off infections and illnesses, and you may be more likely to get sick. This is because steroids can decrease the number of white blood cells in your body, which are responsible for fighting ...
When asleep, cancer cells can evade chemo. When they wake up, they can cause cancer recurrence. By deciphering dormancy cues, labs explore how to break this cycle. This is a preview of subscription content, access via your institution Access options Access Nature and 54 other Nature Portfolio...
