Herein, we report the role and mechanism of activating transcription factor 3 (ATF3), a member of the ATF/cAMP-responsive element-binding protein family of transcription factors in HCC.
In this study, we identified lectin from Bandeiraea simplicifolia seeds (BS-I) binds to metastasis-associated HCC cell surface glycans by a lectin microarray and inhibits HCC cell migration and invasion through downregulating the matrix metalloproteinase 2 (MMP2), matrix metalloproteinase 9 (MMP9) and urokinase-type plasminogen activator (uPA) production.
In human hepatocellular carcinoma (HCC), the high expression of urokinase-type plasminogen activator (uPA) is an unfavorable prognostic factor and a therapeutic target.
The purpose of this study was to examine the effects of vector-based RNA interference (RNAi) of u-PA on the growth of human HCC xenografts in nude mice in order to investigate the role of u-PA in human HCC.
To determine the role of u-PA in the invasiveness properties of HCC, we successfully down-regulated u-PA by RNA interference (RNAi) technology, in an HCC-derived cell line at high level of u-PA expression.
Both the PEA3--AP-1 element, the AP-1 site and the COM are required for efficient phorbol ester induction of transcription from the uPA promoter in the HepG2 hepatoma cell line.
