abstract = {Obesity and excess adiposity account for approximately
$20\%$ of all cancer cases; however, biomarkers of risk
remain to be elucidated. While fibroblast growth factor-2
(FGF2) is emerging as an attractive candidate biomarker for
visceral adipose tissue mass, the role of circulating FGF2
in malignant transformation remains unknown. Moreover,
functional assays for biomarker discovery are limited. We
sought to determine if human serum could stimulate the 3D
growth of a non-tumorigenic cell line. This type of
anchorage-independent 3D growth in soft agar is a surrogate
marker for acquired tumorigenicity of cell lines. We found
that human serum from cancer-free men and women has the
potential to stimulate growth in soft agar of
non-tumorigenic epithelial JB6 P+ cells. We examined
circulating levels of FGF2 in humans in malignant
transformation in vitro in a pilot study of n = 33 men and
women. Serum FGF2 levels were not associated with colony
formation in epithelial cells (r = 0.05, p = 0.80); however,
a fibroblast growth factor receptor-1 (FGFR1) selective
inhibitor significantly blocked serum-stimulated
transformation, suggesting that FGF2 activation of FGFR1 may
be necessary, but not sufficient for the transforming
effects of human serum. This pilot study indicates that the
FGF2/FGFR1 axis plays a role in JB6 P+ malignant
transformation and describes an assay to determine critical
serum factors that have the potential to promote
tumorigenesis.},
