Ginsenosides, the primary pharmacologically active constituents of the genus, have demonstrated a variety of medicinal properties, including anticardiovascular disease, cytotoxic, antiaging, and antidiabetes effects. However, the low concentration of ginsenosides in plants and the challenges associated with their extraction impede the advancement and application of ginsenosides. Heterologous biosynthesis represents a promising strategy for the targeted production of these natural active compounds.

In this study, we used Slc45a2-deficient melanocyte and mouse models to elucidate the roles of SLC45A2 in melanogenesis and melanoma metastasis. We found that the acidified cellular environment impairs the activity of key melanogenic enzyme tyrosinase in Slc45a2-deficient melanocytes.

Using STAT3 inhibitors as a potential strategy in cancer therapy have attracted much attention. Recently, celastrol has been reported that it could directly bind to and suppress the activity of STAT3 in the cardiac dysfunction model. To explore more effective STAT3 inhibiting anti-tumour drug candidates, we synthesised a series of celastrol derivatives and biologically evaluated them with several human cancer cell lines.

According to numerous epidemiological studies, aspirin is a non-steroidal anti-inflammatory drug (NSAID) that reduces the occurrence and mortality of colorectal cancer (CRC). However, the underlying mechanisms are not well identified. In an effort to fill these gaps, we administered aspirin on mice one day before induction in an azoxymethane (AOM)/dextran sulfate sodium (DSS) induced CRC model.

A novel platform of oral insulin delivery is herein proposed based on amphiphilic cholesterol-phosphate conjugate (CHP). The CHP was synthesized with a cholesterol moiety as a hydrophobic block and a phosphate group as a hydrophilic block.
