Inhibition of Telomerase:Is it Promising for Cancer Therapy?
The enzyme telomerase has been found to be active in almost 90% of all cancers. This article describes how telomerase permits cancer cells to continue to divide and multiply, and efforts to develop telomerase inhibitors that promise to halt its progress.

Cancer Stem Cells
Cancer stem cells constitute only a very small portion of tumors yet play a key role in the proliferation of cancer. Cancer stem cells may be inherently resistant to chemotherapeutic drugs. Cancers that result from chronic tissue injury may be due to excessive activation of stem cells.
