Deletion of HST1 blocks the residual replicative lifespan extension by hxk2 mutant in a sir2;fob1;hst2 triple mutant background [16051752]. However, DR can increases the replicative lifespan to a similar extent in sir2;fob1;hst1;hst2 quadruple mutant cells as in sir2;fob1 double mutant cells under 0.5, 0.05 and 0.005% glucose conditions and even by hxk2 deletion mutant [16741098; 17129213].
