About Biology: Human Anatomy, Genetics, and Quizzes
Researchers have used fluorescence microscopy to visually demonstrate gene activity in cancer cells during the cell cycle. Cancer cells divide uncontrollably and may develop as a result of several factors, including recombination errors that occur during the cell cycle and infections from certain cancer viruses. According to head researcher Angus Lamond, "What we have been able to produce is a detailed analysis of protein activity in human cancer cells that exceeds what was previously possible. Previously it has been possible to capture a time-averaged snapshot of this activity, but what we can now do is give a much fuller picture." The researchers state that this new high-resolution mapping of gene expression will provide valuable insight into protein production in cancer cells. Information gained from the detailed study of cancer cell protein activity could lead to the development of better cancer drugs.
