Figure 7. p19(ARF) increases L-lactate production. Stable fibroblast cell lines were subjected to chronic hypoxia for 48 h. Then, the levels of L-lactate that accumulated in the tissue-culture media were assessed and normalized to the amount of total cellular protein. Note that p(19)ARF expression increases L-lactate accumulation by > 2-fold.
