The molecular pathogenesis of hepatocellular carcinoma (HCC) is heterogeneous and
extremely complex. Thus, for individual molecular targeted therapy, novel
molecular markers are needed. The abnormal expression of the human homolog of
Drosophila headcase (HECA homo) has been found in pancreatic, colorectal, and
oral squamous cell carcinoma. Studies of oral squamous cell carcinoma have also
demonstrated that the HECA homo protein can be negatively controlled by the
Wnt-pathway and transcription factor 4 (TCF4) and can slow cell division by
interacting with cyclins and CDKs. However, the role of HECA in HCC has not been
reported elsewhere. Here, immunohistochemical analysis revealed that the
downregulation of HECA homo protein occurred in 71.0% (66/93) of HCC cases and
was positively correlated with a poorly differentiated grade, high serum AFP
level, liver cirrhosis and large tumor size. The expression of HECA homo was
detected in five live cell lines. In vitro, the overexpression of HECA homo in
HepG2, Huh-7 and MHCC-97H cells could inhibit cell proliferation and colony
formation and induce G1 phase arrest. In contrast, the downregulation of HECA
homo could promote cell proliferation, colony formation and the cell cycle
process. However, neither the overexpression nor downregulation of HECA homo in
the three cell lines could affect cell migration or invasion. Collectively, HECA
homo is regularly expressed in normal live cells, and the HECA homo protein level
is heterogeneously altered in HCC, but the downregulation of HECA homo is more
common and positively correlated with several malignant phenotypes. The HECA homo
protein can slow cell proliferation to some extent primarily through its blocking
effect on the cell cycle. Hence, the HECA homo protein may act as a tumor
suppressor in HCC and might be a potential molecular marker for diagnostic
classification and targeted therapy in HCC.
