Abstract
Background: Adipocyte enhancer-binding protein 1 (AEBP1) regulates collagen fibrosis, extracellular matrix, and important oncogene pathways, but its regulation on hepatocellular carcinoma (HCC) is not known. This study aimed to investigate the effect of AEBP1 knockdown on HCC cell proliferation, apoptosis, migration, invasion and PI3K/AKT pathway.
Methods: MHCC-97 H and Huh7 cell lines were applied. Negative control or AEBP1 siRNA (siAEBP1) were transfected into cells, and cells without transfection were set as blank control. Quantitative polymerase chain reaction (qPCR), western blot, Cell Counting Kit-8 (CCK-8), 5-Ethynyl-2'-deoxyuridine (EdU) staining, Terminal-deoxynucleotidyl Transferase Mediated Nick End Labeling (TUNEL) staining, Transwell invasion, and cell scratch assays were performed.
Results: AEBP1 mRNA and protein expressions were lower after siAEBP1 transfection in MHCC-97 H and Huh7 cells. OD value of CCK-8 and EdU positive cell percentage were decreased, while TUNEL reflected cell apoptosis rate was increased, after siAEBP1 transfection in MHCC-97 H and Huh7 cells. However, invasive cell number and cell migration rate were only reduced after siAEBP1 transfection in Huh7 cells but not in MHCC-97 H cells. Expressions of p-PI3K/PI3K and p-AKT/AKT were downregulated after siAEBP1 transfection in MHCC-97 H and Huh7 cells. Subsequent rescue experiment revealed that th activation of PI3K/AKT pathway by 740Y-P attenuated the effect of siAEBP1 transfection in MHCC-97 H and Huh7 cells.
Conclusion: AEBP1 exhibits the potency to be a target for HCC treatment, reflected by its regulation on HCC proliferation, apoptosis and PI3K/AKT pathway, but its effect on HCC invasion and migration seems limited.
期刊介绍：
World Journal of Surgical Oncology publishes articles related to surgical oncology and its allied subjects, such as epidemiology, cancer research, biomarkers, prevention, pathology, radiology, cancer treatment, clinical trials, multimodality treatment and molecular biology. Emphasis is placed on original research articles. The journal also publishes significant clinical case reports, as well as balanced and timely reviews on selected topics.
Oncology is a multidisciplinary super-speciality of which surgical oncology forms an integral component, especially with solid tumors. Surgical oncologists around the world are involved in research extending from detecting the mechanisms underlying the causation of cancer, to its treatment and prevention. The role of a surgical oncologist extends across the whole continuum of care. With continued developments in diagnosis and treatment, the role of a surgical oncologist is ever-changing. Hence, World Journal of Surgical Oncology aims to keep readers abreast with latest developments that will ultimately influence the work of surgical oncologists.
