Dear Editor,
Ling et al. (1) show convincingly that highly oxygen-depedent organs are more prone
to the toxic effects of D-lactate than liver.
However, dosing of D-lactate in a liver cell culture has other very interesting effects.
Namely, the PI3K/AktPKB/PKC acitivity is decreased which leads to low BAD activity
allowing increased apoptosis (2).
This indicates that D-lactate can also have other significant metabolic effects e.g.
in diabetics who have increased D-lactate burden because of excessive methylglyoxal
from glucose (3).
