Journal of Food and Drug Analysis
Steroidogenic acute regulatory protein (StAR) plays a critical role in the regulation of progesterone (P4) production. Resveratrol (RSV), a natural polyphenol, has beneficial effects on reproductive function. However, its effects on StAR expression and P4 production in human granulosa cells remain undetermined. In this study, we showed the treatment of RSV upregulated StAR expression in human granulosa cells. G protein-coupled estrogen receptor (GPER) and ERK1/2 signaling were involved in RSV-stimulated StAR expression and P4 production. In addition, the expression of a transcriptional repressor, Snail, was downregulated by RSV, which contributed to the RSV-induced induction of StAR expression and P4 production.

Journal of Food and Drug Analysis
This study proposes the use of thiomalic acid–modified Au and Ag nanoparticle mixtures (TMA-Au/AgNP mixes) for the selective detection of tricyclazole. Upon the addition of tricyclazole, the color of TMA-Au/AgNP mixes solution changes from orange-red to lavender (red-shift). According to the density-functional theory calculations, tricyclazole-induced aggregation of TMA-Au/AgNP mixes through electron donor–acceptor interactions was proved. The sensitivity and selectivity of the proposed method are affected by the amount of TMA, volume ratio of TMA-AuNPs to TMA-AgNPs, pH value, and buffer concentration. The ratio of absorbance (A654/A520) of TMA-Au/AgNP mixes solution is proportional to the concentration of …

Journal of Food and Drug Analysis
Pulmonary injury is defined as a progressive inflammation. Extensive pro-inflammatory cytokines are secreted from alveolus, associated with the production of reactive oxygen species (ROS) and apoptosis. The model of endotoxin lipopolysaccharide (LPS)-stimulated lung cells has been applied to mimic the pulmonary injury. Some antioxidants and anti-inflammatory compounds can be used as chemopreventive agents of pulmonary injury. Quercetin-3-glucuronide (Q3G) has been showed to exert antioxidant, anti-inflammatory, anti-cancer, anti-aging and anti-hypertension effects. The aim of the study is to examine the inhibitory potential of Q3G on pulmonary injury and inflammation in vitro and in vivo. Firstly, human lung fibroblasts MRC-5 cells pre-treated …

Recent rapid development of cancer therapy has come about with the paradigm shift from the traditional goal of targeting cancer cells themselves, to reprograming the immune tumor microenvironment. Accumulating evidence shows that compounds that target epigenetic regulation, called epidrugs, play a crucial role in mediating the immunogenicity of cancer cells and in reshaping antitumor immunity. A large body of literature has recognized natural compounds as epigenetic modulators for their immunomodulatory effects and anticancer potential. Unifying our understanding of the role of these biologically active compounds in immuno-oncology may open new avenues for more effective cancer therapies. In this review, we …
