LAMC1 encodes an extracellular matrix protein, laminin ?1 chain, which is
involved in several biological and pathological processes including tissue
development, tumor cell invasion and metastasis. In present study, we
demonstrated that both LAMC1 protein and mRNA levels were elevated in HCC tissue
samples compared with non-cancerous tissue samples according to western blot
analyses, immunohistochemistry (IHC) and microarray. Moreover, high LAMC1
expression was positively correlated with incomplete encapsulation (p=0.014),
poor overall (OS, p=0.02) and disease-free survival (DFS, p=0.014). Using cell
lines, we demonstrated that the levels of LAMC1 mRNA and protein were
significantly higher in HCC cell lines than that in LO2 cell line. After the
expression of LAMC1 was depressed by siRNA technique, the cell proliferation,
migration and invasion were depressed significantly. Taken together, these data
suggest that LAMC1 is enriched in HCC; overexpression of LAMC1 predicts poor
prognosis, and enhances tumor cell invasion and migration. LAMC1 might be a new
biomarker predictive of HCC prognosis and might also be a useful treatment
target.
