Relative pyruvate, GPC and GPE levels were significantly higher in ABCB5-WT vs. ABCB5-KD melanoma cells by a factor of three, two and two (respectively), whereas relative alanine and aspartate increases by about 15% were close to significance (0.05 < p ≤ 0.12; % of totH and totP, Tables 1 and 2). The gene discussed is ABCB5; the disease is melanoma.
