There is accumulating evidence that some biochemical pathways observab
le by magnetic resonance spectroscopy, e.g., citrate acid and phosphol
ipid metabolism, are altered in human prostate cancer. Four well-estab
lished human prostate cancer cell lines were therefore studied with ma
gnetic resonance spectroscopy to compare differences in metabolic cont
ent with tumor biological behavior. Herein we demonstrate that, althou
gh each cell line has its own metabolic profile, relative creatine and
citrate levels can be used to discriminate the androgen-dependent LNC
aP cell line from the androgen-independent DU-145, TSU, and PC-3 cell
lines. (C) 1995 Wiley-Liss, Inc.
