abstract = {According to the cancer stem cell (CSC) hypothesis, the
aggressive growth and early metastasis of pancreatic ductal
adenocarcinoma (PDA) is due to the activity of CSCs, which
are not targeted by current therapies. Otto Warburg
suggested that the growth of cancer cells is driven by a
high glucose metabolism. Here, we investigated whether
glycolysis inhibition targets CSCs and thus may enhance
therapeutic efficacy. Four established and 3 primary PDA
cell lines, non-malignant cells, and 3 patient-tumor-derived
CSC-enriched spheroidal cultures were analyzed by glucose
turnover measurements, MTT and ATP assays, flow cytometry of
ALDH1 activity and annexin positivity, colony and spheroid
formation, western blotting, electrophoretic mobility shift
assay, xenotransplantation, and immunohistochemistry. The
effect of siRNA-mediated inhibition of LDH-A and LDH-B was
also investigated. The PDA cells exhibited a high glucose
metabolism, and glucose withdrawal or LDH inhibition by
siRNA prevented growth and colony formation. Treatment with
the anti-glycolytic agent 3-bromopyruvate almost completely
blocked cell viability, self-renewal potential, NF-κB
binding activity, and stem cell-related signaling and
reverted gemcitabine resistance. 3-bromopyruvate was less
effective in weakly malignant PDA cells and did not affect
non-malignant cells, predicting minimal side effects.
3-bromopyruvate inhibited in vivo tumor engraftment and
growth on chicken eggs and mice and enhanced the efficacy of
gemcitabine by influencing the expression of markers of
proliferation, apoptosis, self-renewal, and metastasis. Most
importantly, primary CSC-enriched spheroidal cultures were
eliminated by 3-bromopyruvate. These findings propose that
CSCs may be specifically dependent on a high glucose
turnover and suggest 3-bromopyruvate for therapeutic
intervention.},
