A team of researchers affiliated with a host of institutions across Japan has found that inhibiting kidney-type glutaminase-dependent glutaminolysis in mice can lead to elimination of senescent cells. In their paper published in the journal Science, the group describes using RNA interference to look for enzymes that are required for senescent cell survival and subsequently inducing them to die. Christopher Pan and Jason Locasale, with the Duke University School of Medicine, have published a Perspectives piece in the same journal issue outlining research into glutamine and the role it played in the work done by the team in this new effort.
