Sorafenib (Nexavar, BAY43‑9006 or Sora) is the first molecular targeted agent that has exhibited significant therapeutic benefits in advanced hepatocellular carcinoma (HCC). However, not all HCC patients respond well to Sora and novel therapeutic strategies to optimize the efficacy of Sora are urgently required. Plant‑based drugs have received increasing attention owing to their excellent chemotherapeutic and chemopreventive activities; they are also well tolerated, non‑toxic, easily available and inexpensive...

BACKGROUND: Shufeng Jiedu Capsule (SFJDC), a traditional Chinese medicine, has been used widely as antiviral, antibacterial, antitumor, and anti-inflammatory drugs. Previous studies indicated that some active ingredients of Shufeng Jiedu Capsule, such as resveratrol and quercetin, could suppress hepatocellular carcinoma (HCC) cells through various signaling pathways. However, anti-HCC activity of SFJDC as a complementary medicine remains unexplored. Here, we use a combination of Shufeng Jiedu Capsule and doxorubicin to treat HCC cells and investigated the effects and mechanisms of SFJDC and its ingredientsin vitro...

Curcumin (1) and resveratrol (2) are bioactive natural compounds that display wide pharmacological properties, including antitumor activity. However, their clinical application has been limited due to their low solubility and bioavailability. Nevertheless, independent studies have considered these compounds as interesting prototypes for developing new chemical structures useful for anticancer therapy. Here in, we report the synthesis of novel curcumin-like hydrazide analogues (3a and 3b), and a series of curcumin-resveratrol hybrid compounds (4a-f), and the evaluation of their cytotoxic potential on three tumor cell lines MCF-7 (breast), A549 (lung), and HepG2 (liver)...

This study was aimed at understanding why dietary polyphenols with a catechol skeleton tend to exhibit cancer chemopreventive activity by using a catechol-type stilbene (3,4-DHS) as a model molecule. Only a short-term cooperation of 3,4-DHS and exogenous Cu(II) exhibited a strong preferential ability to kill HepG2 cells over normal L02 cells. Mechanism studies reveal that this 3,4-DHS/Cu(II) system could produce extracellularly reactive oxygen species (ROS) and o-quinone through two sequential proton loss electron transfer followed by diffusion of ROS into cells, leading to higher intracellular accumulation of ROS, preferential disruption of redox homeostasis and more effective mitochondria-dependent apoptosis as well as necrosis of HepG2 cells than L-02 cells...

Glycine supplementation has been reported to enhance white-fat loss and improve sensitivity to insulin in animals with obesity or type 2 diabetes. However, the underlying mechanisms responsible for the beneficial effects of glycine remain largely unknown. The purpose of this study was to test the hypothesis that glycine regulates adipocyte differentiation, adipogenesis, and lipolysis, therefore, contributing to white-fat reduction. 3T3-L1 pre-adipocytes were induced to differentiate into adipocytes in the presence of glycine (0, 0...

SCOPE: Resveratrol (RSV) has been described as a potent antioxidant, antisteatotic, and antitumor compound, and it has also been identified as a potent autophagy inducer. On the other hand, quercetin (QCT) is a dietary flavonoid with known antitumor, anti-inflammatory, and antidiabetic effects. Additionally, QCT increases autophagy. To study the hypothetical synergistic effect of both compounds, we test the combined effect of QCT and RSV on the autophagy process in HepG2 cells. METHODS AND RESULTS: Autophagy is studied by western blotting, real-time RT-PCR, and cellular staining...

Resveratrol is a promising chemical agent that treats multiple aging-related diseases and improves life span. While reactive oxygen species undoubtedly play ubiquitous roles in the aging process and resveratrol has been shown to be an effective antioxidant, the mechanism through which resveratrol acts against oxidative stress remains unknown. Here we show that resveratrol activates SIRT2 to deacetylate Prx1, leading to an increased H2 O2 reduction activity and a decreased cellular H2 O2 concentration. Knockdown of SIRT2 or Prx1 by RNA interference abrogates resveratrol's ability to reduce the H2 O2 level in HepG2 cells...

Resveratrol (RSV) is a natural polyphenolic compound with high affinity to hepatocytes. It has numerous benefits as anticancer, antioxidant, immunomodulatory and cardioprotective actions. Nevertheless, RSV therapeutic applications are hindered by its low solubility, light sensitivity and extensive first-pass metabolism. Cubosomes are colloidally stable dispersed liquid crystalline nanoparticles. The incorporation of RSV into cubosomes could overcome some of its physicochemical limitations. A Design-Expert® software was applied to optimize cubosomes in terms of particle size and encapsulation efficiency (EE%)...

Both primary hepatocytes and stem cells-derived hepatocyte-like cells (HLCs) are major sources for bioartificial liver (BAL). Maintenance of hepatocellular functions and induction of functional maturity of HLCs are critical for BAL's support effect. It remains difficult to assess and improve detoxification functions inherent to hepatocytes, including ammonia clearance. Here, we aim to assess ammonia metabolism and identify ammonia detoxification enhancer by developing an imaging strategy. In hepatoma cell line HepG2, and immortalized hepatic cell line LO2, carbamoyl phosphate synthetase 1 (CPS1) gene, the first enzyme of ammonia-eliminating urea cycle, was labelled with fluorescence protein via CRISPR/Cas9 system...

Hepatocellular carcinoma (HCC) is characterized by hypervascularity. Hepatic stellate cells (HSCs) play very important roles in HCC malignant progression, as these cells facilitate HCC tumorigenesis and metastasis. We demonstrated that HSCs induce angiogenesis in HCC by upregulating the expression of Gli-1, which stimulates reactive oxygen species (ROS) production and potentiates increases in HCC cell invasiveness. Resveratrol abolished HSC-induced angiogenesis and suppressed ROS production and IL-6 and CXCR4 receptor expression in HepG2 cells by down-regulating Gli-1 expression...

Cell apoptosis often induces inflammation and injury in the liver, with endoplasmic reticulum (ER) stress as the most possible reason. Resveratrol (RSV) has been shown to prevent hepatic steatosis and alleviate apoptosis, however, the exact mechanisms underlying the effects still need to be explored. Here we co-cultured HepG2 cells with free fatty acid (FFA) solution (oleic acid: palmitic acid = 2:1) and then exposed to a carbon tetrachloride (CCl4) solution to induce apoptosis. To evaluate the therapeutic effects, RSV (2...
