In a new evolutionary proof of the old adage, ‘we are what we eat’, Cornell University scientists have found tantalizing evidence that a vegetarian diet has led to a mutation that — if they stray from a balanced omega-6 to omega-3 diet — may make people more susceptible to inflammation, and by association, increased risk of heart disease and colon…
Research from Rutgers Cancer Institute of New Jersey examining difficult to treat cancer tumors through genomic profiling shows that tumors with alterations in a signaling pathway responsible for cell regulation may respond to targeted therapy regardless of where the tumor originated in the body. The findings will be presented as part of a poster presentation by members of the Rutgers…
Now that everyone who wants to sound sophisticated about health care is talking about “personalized medicine”—even the president!—the open question is, what part of medicine is going to get personalized first? Which is to say, what can the intricacies of people’s genomes say about the best way to treat what ails them? The answers may well be in blood. Why…
UK scientists have been given the go-ahead by the fertility regulator to genetically modify human embryos. It is the first time a country has considered the DNA-altering technique in embryos and approved it. The research will take place at the Francis Crick Institute in London and aims to provide a deeper understanding of the earliest moments of human life. The…
The Y chromosome is a symbol of maleness, present only in males and encoding genes important for male reproduction. But a new study has shown that live mouse progeny can be generated with assisted reproduction using germ cells from males which do not have any Y chromosome genes. This discovery adds a new light to discussions on Y chromosome gene…
Humans have been successful at treating a host of diseases. Yet some continue to elude medicine’s best attempts. Now, researchers at the University of Iowa have revealed how these diseases replicate by tracing the precise steps through which they use a gene absent in humans, called thyX, to code an enzyme to produce thymine. In a paper published online Jan. 28…
