Prostate cancer is the leading cause of cancer morbidity and the third greatest cause of cancer death among men in developed countries. A major question in cancer research has been whether virus infection plays a role in cancers of the genitourinary tract. Now a team of Swiss investigators has n... Read More
Merry Youle of the Small Things Considered blog has a new post up that looks at the phage-encoded holin timer and its function in a lytic infection.
"Holins are the smallest known biological timers. Timers, not clocks. Timers tick along, then go off after the specified interval. These small, ... Read More
