I just booked a seat at the lecture called ‘DNA Ends – Just the Beginning’ by professor Jack W. Szostak. He has received several awards, with the latest being Nobel Prize for Physiology or Medicine (which he shared with Elizabeth Blackburn and Carol W. Greider). With only 30 seats left I managed to get one, and I can’t wait to meet him.
Together with his colleagues they discovered a mechanism that clarify how chromosomes are protected from degrading. This mechanism is very important for learning more about how cancer works, and how we can affect cancer growth in the future.
In the human body, most cells can only divide a limited number of times to give way to new ‘fresh’ cells. But most normal human cells can only divide a limited number of times. This process, where a cell divides, is called mitosis. Telomeres, that are protective bits of DNA, shorten with time and division – this is called cell degradation and is a normal ageing process. Cancer cells can bypass this by activating the enzyme telomerase, and therefore continue to grow unlimited. I am so excited, although I have a very important test the next day- but we have been reading about cancer the last week- making this lecture even more interesting.

While we all should know by now that smoking increases the risk of mouth cancer, by nine times, dental researchers say now that alcohol containing mouthwashes can also cause harm.
They claim that drinking alcohol and the use of mouthwash containing more than 20% alcohol increases the risk of oral cancer almost as much as smoking. A closer look at review literature (comparison of studies in that field), gave me no supporting evidence. Abuse of alcohol combined with smoking can enhance cancer risk, but ethanol itself is not carcinogenic (cancer-causing). There is no evidence that mouthwashes with alcohol increases cancer risk. Alcoholic beverages and smoking both increases cancer risk, both cancer of the mouth and other cancer types.
