Cold Spring Harbor Protocols features methods to screen genomes and analyze evolution
April 02, 2008Identifying genes that are important in specific tissues or processes in the mouse used to be a monumental task. New technologies and strategies have simplified this search, making it effective for even the smallest laboratories. This month's issue of Cold Spring Harbor Protocols (www.cshprotocols.org/TOCs/toc4_08.dtl) highlights a method for screening the mouse genome using ENU mutagenesis. The method, "Mouse Mutagenesis Using N-ethyl-N-nitrosourea (ENU)," was submitted by Monica Justice and colleagues from the Baylor College of Medicine http://www.bcm.edu/db/db_fac-justice.html). In her laboratory, Justice uses this "forward genetics" method to identify genes that may play a role in human disease. In particular, Justice's lab focuses on the process of hematopoiesis, the development of blood cells. Mutations in these genes can lead to leukemias or lymphomas. The method is freely accessible on the website for Cold Spring Harbor Protocols (http://www.cshprotocols.org/cgi/content/full/2008/5/pdb.prot4985).
The second featured protocol for April is a guide for selecting the proper method for analyzing evolutionary relationships between genes. In "Choosing a Method for Phylogenetic Prediction," David Mount from the University of Arizona (http://bmcb.biology.arizona.edu/mount.html) provides a step by step process to determine which of the major methods one should use for predicting "phylogeny", the relatedness among gene sequences. The method is freely accessible on the website for Cold Spring Harbor Protocols (http://www.cshprotocols.org/cgi/content/full/2008/5/pdb.ip49).

Misreading of damaged DNA may spur tumor formation
The DNA in our cells is constantly under assault from oxygen, the sun's radiation and environmental stresses. Most of the time, our cells can repair the damage before it gets copied into a permanent mutation that could lead to cancer.

A five-year study that could help increase disease resistance, stress tolerance and plant yields is under way at Purdue University.
Forced evolution: Can we mutate viruses to death?
It sounds like a science fiction movie: A killer contagion threatens the Earth, but scientists save the day with a designer drug that forces the virus to mutate itself out of existence. The killer disease? Still a fiction. The drug? It could become a reality thanks to a new study by Rice University bioengineers.
