However, the novel mechanism of AHSA1 in the tumor biology of hepatocellular carcinoma (HCC) remains unclear.Methods: We analyzed AHSA1 expression in 85 pairs of clinical samples of HCC and the Cancer Genome Atlas database. The role of AHSA1 in HCC was proved by cell proliferation, colony formation, migration, cell cycle analysis in vitro, xenograft models and tumor metastasis assay in vivo, and bioinformatics.Results: High AHSA1 expression was demonstrated in HCC and associated with invasive depth, clinical stage, and poor overall survival of patients. Univariate Cox analysis confirmed that AHSA1 was an independent prognostic factor for patients with HCC. Meanwhile, AHSA1 upregulation promoted cell proliferation, colony formation, and cell migration in vitro and tumor cell proliferation and metastasis of HCC cells in vivo. AHSA1 upregulation increased the cell cycle transition from G1 to S phase by increasing the expression of cyclinD1, cyclinD3, and cyclin-dependent kinase 6(CD). Transforming growth factor beta 1 (TGF-β 1)-induced protein kinase B (Akt) signaling regulated the expression of downstream targets, including cyclinD1. AHSA1 expression was closely correlated with the expression of TGF-β, Akt, cyclinD1, cyclinD3, and CDK6 using the Gene Expression Profiling Interactive Analysis database. AHSA1 upregulation participated in HCC progression by regulating TGF-β/Akt-cyclinD1/CDK6 signaling.Conclusion: AHSA1 might serve as a biomarker for predicting the clinical outcome of patients with HCC. It is vital in tumor metastasis and disease progression of HCC and may facilitate the development of clinical intervention strategies against HCC.Keywords: AHSA1, AKT/cyclinD1/CDK6 signaling, cell cycle, hepatocellular carcinoma, TGF-β
