Hepatocyte growth factor (HGF), and its receptor, c-Met activation has recently been shown to play important roles in cancer invasion and metastasis in a wide variety of tumor cells. We use HGF as an invasive inducer of human HepG2 cells to investigate the effect of four flavones including apigenin, tricetin, tangeretin, and nobiletin on HGF/c-Met-mediated tumor invasion and metastasis. Among them, nobiletin markedly inhibited HGF-induced the abilities of the adhesion, invasion, and migration by cell-matrix adhesion assay and transwell-chamber invasion/migration assay under non-cytotoxic concentrations. Data also showed nobiletin inhibited HGF-induced cell scattering and cytoskeleton changed such as filopodia and lamellipodia. Furthermore, nobiletin could inhibit HGF-induced the membrane localization of phosphorylated c-Met, ERK2, and Akt, but not phosphorylated JNK1/2 and p38. Next, nobiletin significantly decreased the levels of phospho-ERK2 and phospho-Akt in ERK2 or Akt siRNA-transfected cells concomitantly with a marked reduction on cell invasion and migration. In conclusion, nobiletin attenuates HGF-induced HepG2 cells metastasis involving both ERK and PI3K/Akt pathways and are potentially useful as anti-metastatic agents for the treatment of hepatoma.

Podophyllotoxin, along with its numerous derivatives and related compounds, is well known for its broad-spectrum pharmacological activity, especially for anticancer potential. In this study, several isatin-podophyllotoxin hybrid compounds were successfully synthesized with good yields through microwave-prompted three-component reactions of 2-amino-1,4-naphthoquinone, various substituted isatins, and tetronic acid. Their cytotoxicity was assessed against four types of human cancer cell lines, HepG2 (hepatoma carcinoma), MCF7 (breast cancer), A549 (non-small lung cancer), and KB (epidermoid carcinoma), alongside nontumorigenic HEK-293 human embryonic kidney cells.

Methods: This study sought to ascertain potential shared genes between AH and HCC through the utilization of multiple transcriptome databases.

Hepatocellular carcinoma (HCC) stands as a grave illness characterized by elevated death rates. Early identification plays a vital role in improving patient survival. Herein, a novel split-type dual-mode biosensor featuring with near-infrared photoelectronchemical (PEC) and colorimetric sensing characteristics was developed for the high-performance detection of HepG2 cells.

Background: Exogenous Cushing's syndrome, which results from prolonged glucocorticoid treatment, is associated with metabolic abnormalities. Previously, we reported the inhibitory effect of tonsil-derived mesenchymal stem cell conditioned medium (T-MSC CM) on glucocorticoid signal transduction. In this study, we investigated the therapeutic efficacy of T-MSCs in a mouse model of exogenous Cushing's syndrome.

Purpose: Major depressive disorder is one of the most common and burdensome psychiatric disorders worldwide. This study evaluated the anxiolytic- and antidepressant-like activity of three semi-synthetic derivatives of xylopic acid (XA) to identify the most promising derivative based on mechanism(s) of action, in vivo pharmacokinetics and in vitro cytotoxicity.
Methods: The anxiolytic potential and the involvement of GABAergic mechanisms were assessed in the elevated plus-maze and open field tests in mice.
