Cancer metastasis is a complex process, and the incidence of metastasis is
influenced by many biological factors. Orosomucoid 2 (ORM2) is an important
glycoprotein that is mainly biosynthesized and secreted by hepatocytes. As an
acute-phase protein, ORM2 likely plays important roles in anti-inflammation,
immunomodulation and drug delivery. However, little is known regarding the
function of ORM2 in hepatocellular carcinoma (HCC). In this study, we determined
that ORM2 expression in HCC tissues was negatively associated with intrahepatic
metastasis and histological grade. Moreover, the ectopic overexpression of ORM2
decreased HCC cell migration and invasion in vitro and intrahepatic metastasis in
vivo, whereas silencing ORM2 expression resulted in increased tumor cell
migration and invasion in vitro. The CCAAT/enhancer binding protein ? (C/EBP?)
upregulated ORM2 expression, while only the LAP1/2 (C/EBP? isoforms) possessed
transcription-promoting activity on the ORM2 promoter. Subsequently, we found
that LAP1 repressed HCC cell migration and invasion via the induction of ORM2
expression. Consistently, the protein expression of C/EBP? was negatively
associated with histological grade and positively correlated with ORM2 protein
expression in HCC tissues. Collectively, our findings indicate that ORM2 is a
functional downstream target of C/EBP? and functions as a tumor suppressor in
HCC.
