LRP1 and hepatocellular carcinoma: Cell Counting Kit‐8 (CCK‐8), colony formation, and scratch wound healing assays indicated that overexpression of LRP1 or its β‐chain, rather than the α‐chain, markedly suppressed the proliferation and migration of PLC5 and Huh‐7 cells, accompanied by enhanced apoptosis, implicating a fundamental role for the LRP1 β‐chain in the HCC process (Figure 2c–f; Figure S1b–e, Supporting Information).
