Cancer associated fibroblasts (CAFs) are a crucial cellular component in tumor
microenvironment and could promote tumor progression. CAFs are usually derived
from resident fibroblasts, which undergoing an activated process stimulated by
tumor cells. However, the agents and mechanism driving this switch have not yet
been elucidated. Progranulin (PGRN), a well acknowledged secreted glycoprotein,
could promote proliferation and angiogenesis of colorectal cancer (CRC) cells,
and high expression of PGRN correlated with patient poor prognosis. Whether PGRN
has effects on the function of stromal fibroblasts is unknown. Herein we found
that there was a positive correlation between PGRN expression of CRC cells and
expressions of smooth muscle actin ? (?-SMA) on CAFs in CRC patient tissues.
PGRN/?-SMA co-expression was positively correlated with CRC patient poor
prognosis. Co-cultured with CRC cells or human recombinant PGRN (rPGRN), the
expression of Ki67, fibroblast activation protein (FAP) and ?-SMA in fibroblasts
were all up-regulated significantly, accompanying with elevated cellular
proliferation, migration and contraction. Whilst co-cultured with PGRN-silenced
CRC cells, these functions were down-regulated. Studies of the underlying
molecular mechanism demonstrated that either tumor necrosis factor receptor 2
(TNFR2)/Akt or the extracellular regulated kinase (ERK) signaling pathway
contributed to modulate of Ki67, FAP, and ?-SMA expression, and correlated to
abilities of proliferation, migration and contraction in fibroblasts. In
conclusion, PGRN plays an important role in activation of CRC fibroblasts, which
may be taken as a prospective target of CRC therapy.
