Bone morphogenetic proteins (BMPs) are growth factors that have important
functions in cell proliferation, migration and differentiation. To date, BMP
pathway activation has been found in multiple human tumors and is associated with
enhanced malignant tumor growth and metastasis. BMP activity is tightly regulated
by a family of soluble extracellular secreted BMP modulators. Twisted
gastrulation BMP signaling modulator 1 (TWSG1) is a direct BMP regulator that is
required for the full signaling activity of BMPs. However, the functions and
mechanisms of TWSG1 in papillary thyroid cancer (PTC) metastasis have not been
reported. TWSG1 expression was detected in 44 PTC tissues with lymph node
metastasis (LNM) and 56 PTC tissues without LNM using quantitative real-time
polymerase chain reaction (qRT-PCR). Gain- and loss-of-function approaches were
used to assess the biological function of TWSG1 in PTC cells. Matrigel assays
demonstrated the effect of tumor cell-derived TWSG1 on endothelial cell function.
Our results showed that TWSG1 expression was significantly enhanced in PTC with
LNM compared to that in PTC without LNM. TWSG1 knockdown inhibited migration,
invasion and proliferation of PTC cells. Additionally, TWSG1 suppression impaired
the tumor cell-induced endothelial cell sprout formation. We found that TWSG1
signaling may be transduced by the BMP target transcription factor inhibitor of
DNA binding 1 (Id1) and matrix metalloproteinases (MMPs) 2 and 9. In conclusion,
TWSG1 was highly expressed in metastasized PTC; tumor growth, migration and
invasion were dependent on TWSG1, and it may be a new diagnostic and therapeutic
target for PTC.
