Differential regulation of baicalin and scutellarin on AMPK and Akt in promoting adipose cell glucose disposal
In conclusion, baicalin and scutellarin, though structurally similar, promoted glucose disposal in adipocytes by differential regulation on AMPK and Akt activity. Our data provide insight that multicomponent herbal medicines may act synergistically and cooperatively on multiple targets. Graphical abstract

Shikonin-induced necroptosis is enhanced by the inhibition of autophagy in non-small cell lung cancer cells
In conclusion, our data indicated that shikonin treatment induced necroptosis and autophagy in NSCLC cells. In addition, inhibition of shikonin-induced autophagy enhanced necroptosis, suggesting that shikonin could be a novel therapeutic strategy against NSCLC.

Berberine Hydrochloride Protects C2C12 Myoblast Cells Against Oxidative Stress ‐Induced Damage via Induction of Nrf‐2‐Mediated HO‐1 Expression
ABSTRACT
The aim of the present study was to evaluate the effects of berberine hydrochloride (BBH), an isoquinoline alkaloid that can be isolated from a variety of herbs, on hydrogen peroxide (H2O2)‐induced oxidative stress in C2C12 myoblasts and to investigate the molecular mechanisms involved in this process, especially the expression of the Nrf2/HO‐1 pathway. BBH preconditioning attenuated H2O2‐induced growth inhibition and DNA damage as well as apoptosis in C2C12 cells via suppression of the accumulation of intracellular reactive oxygen species (ROS). Treatment with BBHride alone effectively upregulated th...

Modified Panax ginseng Extract Inhibits uPAR-Mediated αFormula: see textβ1-Integrin Signaling by Modulating Caveolin-1 to Induce Early Apoptosis in Lung Cancer Cells.
Abstract
Urokinase receptor (uPAR) is enhanced in many human cancer cells and is frequently an indicator of poor prognosis. Activation of [Formula: see text]1-integrin requires caveolin-1 and is regulated by uPAR. However, the underlying molecular mechanism responsible for the interaction between uPAR and [Formula: see text]1-integrin remains obscure. We found that modified regular Panax ginseng extract (MRGX) had a negative modulating effect on the uPAR/[Formula: see text]1-integrin interaction, disrupted the uPAR/integrin interaction by modulating caveoline-1, and caused early apoptosis in cancer cells. Addition...

Astragalus polysaccharide induces the apoptosis of human hepatocellular carcinoma cells by decreasing the expression of Notch1.
Abstract
Hepatocellular carcinoma (HCC) is the third most frequent cause of cancer death worldwide. Astragalus polysaccharide (APS), the primary active component extracted from a traditional Chinese medicinal herb Astragalus membranaceus, has been proved to exert a marked inhibitory effect on a number of types of human solid tumors. In the present study, we aimed to examine the effects of APS on the survival of the HCC cell line H22 and to elucidate the underlying regulatory mechanisms responsible for these effects. Our results revealed that the mRNA and protein expression of Notch1 was significantly upregulate...

Gypenoside Attenuates β Amyloid-Induced Inflammation in N9 Microglial Cells via SOCS1 Signaling.
In this study, we hypothesized that GP attenuates Aβ-induced microglial activation by ameliorating microglial M1/M2 states, and the process may be mediated by suppressor of cell signaling protein 1 (SOCS1). In this study, we found that Aβ exposure increased the levels of microglial M1 markers, including iNOS expression, tumor necrosis factor α (TNF-α), interleukin 1β (IL-1β), and IL-6 releases, and coadministration of GP reversed the increase of M1 markers and enhanced the levels of M2 markers, including arginase-1 (Arg-1) expression, IL-10, brain-derived neurotrophic factor (BDNF), and glial cell-derived neurotrophi...

Ophiopogonin B induces apoptosis, mitotic catastrophe and autophagy in A549 cells.
Abstract
Ophiopogonin B (OP-B), a saponin compound isolated from Radix Ophiopogon japonicus, was verified to inhibit cell proliferation in numerous non-small cell lung cancer (NSCLC) cells in our previous study. However, the precise mechanisms of action have remained unclear. In the present study, we mainly investigated the effects of OP-B on adenocarcinoma A549 cells to further elaborate the underlying mechanisms of OP-B in different NSCLC cell lines. Detection by high content screening (HCS) and TUNEL assay verified that OP-B induced apoptosis in this cell line, while detection of Caspase-3, Bcl-2 and Bax showed...

Geniposide Suppresses Hepatic Glucose Production via AMPK in HepG2 Cells.
This study was designed to determine, for the first time, how geniposide from G. jasminoides regulates hepatic glucose production, and the underlying mechanisms. During in vitro study, we found the inhibitory effect of geniposide on the hepatic glucose production is partly through AMP-activated protein kinase (AMPK) activation in HepG2 cells. Geniposide significantly inhibited hepatic glucose production in a dose-dependent manner. AMPK, acetyl coenzyme A synthetase (ACC) and forkhead box class O1 (FoxO1) phosphorylation were stimulated by different concentrations of geniposide. In addition, the enzyme activities of phosp...

Nerve Regeneration Potential of Protocatechuic Acid in RSC96 Schwann Cells by Induction of Cellular Proliferation and Migration through IGFR-PI3K-Akt Signaling.
This study investigated the molecular mechanisms by which PCA induces Schwann cell proliferation by activating IGFR-PI3K-Akt pathway. Treatment with PCA induces phosphorylation of the insulin-like growth factor-I (IGF-I)-mediated phosphatidylinositol 3 kinase/serine - threonine kinase (PI3K/Akt) pathway, and activates expression of cell nuclear antigen (PCNA) in a dose-dependent manner. Cell cycle analysis after 18 h of treatment showed that proliferation of the RSC96 cells was enhanced by PCA treatment. The PCA induced proliferation was accompanied by modulation in the expressions of cell cycle proteins cyclin D1, cyclin ...

Tanshinone IIA Prevents Leu27IGF-II-induced Cardiomyocyte Hypertrophy Mediated by Estrogen Receptor and Subsequent Akt Activation.
This study investigates the role of ER signaling in mediating the protective effects of tanshinone IIA on IGF-IIR-induced myocardial hypertrophy. Leu27IGF-II (IGF-II analog) was shown in this study to specifically activate IGF-IIR expression and ICI 182,780 (ICI), an ER antagonist used to investigate tanshinone IIA estrogenic activity. We demonstrated that tanshinone IIA significantly enhanced Akt phosphorylation through ER activation to inhibit Leu27IGF-II-induced calcineurin expression and subsequent NFATc3 nuclear translocation to suppress myocardial hypertrophy. Tanshinone IIA reduced the cell size and suppressed ANP a...
