New program interrogates gene pathways
...utrients. Says Gifford, "We could see how the cell reprograms
various aspects of metabolism that deal with starvation. We could also see how the expression of key genes changes." In the near future, pharmaceutical companies may start developing therapeutics that target an entire network pathway, rather than jus...
Cloning can turn back the developmental clock
... the placenta," says Jaenisch. "Although the egg reprograms
some aspects of X-inactivation, for instance, turning on genes in the silent X chromosome, there clearly are other aspects that the egg ignores, namely the marks that lead to imprinted X-inactivation in the placenta,"says Eggan. "It is expected that ...
Researchers find key to tuberculosis persistence in the body
...inney. The research suggested that M. tuberculosis reprograms
its carbon metabolism in response to the activation of certain immune cells-called macrophages-in the host. This idea was confirmed in subsequent experiments. Russell and colleagues showed that the mutant bacteria were unable to survive in immune-act...
Cloning reverses aging in cow cells, Scienceauthors say
...r work to discover exactly how the cloning process reprograms
the youth back into cells. In the meantime, future possibilities for these cells could include their use in engineering replacement tissues for humans. "The extra population doublings of these cells means that we could get a billionfold increase in t...
