Abstract

Hepatocellular carcinoma(HCC) is a malignant tumor with high mortality due to lack of early diagnostic methods and effective treatments, and the molecular mechanisms are intricate and remain unclear. In the present study, the role of macrophage receptor with collagenous structure (MARCO) in tumor advancement of HCC was investigated. We examined expression level of MARCO in HCC samples, corresponding adjacent nontumor tissues and six hepatoma cell lines by polymerase chain reaction and immunohistochemistry (IHC). Clinical information of HCC patients was also analyzed. The role of MARCO involved in HCC progression via multiple functional experiments in vitro and in vivo was investigated. Bioinformatics analysis was conducted to further explore biological functions of MARCO. We found MARCO was suggestively down-regulated in HCC and associated with favorable prognosis, and MARCO upregulation oppressed tumor cell migration and invasion. Besides, overexpression of MARCO not only promoted apoptosis of hepatoma cells but also suppressed proliferation in vivo and in vitro. Furthermore, gene set enrichment analysis (GSEA) analysis suggested that MARCO may be related to the P53 signaling pathway, and this prediction was confirmed in this ...Continue Reading

Apoptosis in Cancer

Apoptosis is an important mechanism in cancer. By evading apoptosis, tumors can continue to grow without regulation and metastasize systemically. Many therapies are evaluating the use of pro-apoptotic activation to eliminate cancer growth. Here is the latest research on apoptosis in cancer.

Apoptosis

Apoptosis is a specific process that leads to programmed cell death through the activation of an evolutionary conserved intracellular pathway leading to pathognomic cellular changes distinct from cellular necrosis
