Grifolin, a farnesyl phenolic compound isolated from the fresh fruiting bodies of
the mushroom Albatrellus confluens, exhibits effective antitumor bioactivity in
previous study of our group and other lab. In this study, we observed that
grifolin inhibited tumor cells adhesion and migration. Moreover, grifolin reduced
reactive oxygen species (ROS) production and caused cellular ATP depletion in
high-metastatic tumor cells. PGC1? (Peroxisome proliferator-activated receptor ?,
coactivator 1?) encodes a transcriptional co-activator involved in mitochondrial
biogenesis and respiration and play a critical role in the maintenance of energy
homeostasis. Interestingly, grifolin suppressed the mRNA as well as protein level
of PGC1?. We further identified that MMP2 and CD44 expressions were PGC1?
inducible. PGC1? can bind with metastatic-associated transcription factors: Fra-1
and LSF and the protein-protein interaction was attenuated by grifolin treatment.
Overall, these findings suggest that grifolin decreased ROS generation and
intracellular ATP to suppress tumor cell adhesion/migration via impeding the
interplay between PGC1? and Fra-1 /LSF-MMP2/CD44 axes. Grifolin may develop as a
promising lead compound for antitumor therapies by targeting energy metabolism
regulator PGC1? signaling.
