Taxol, a kind of terpenoid secondary metabolite produced by Taxus brevifolia, is an effective anticancer drug that manufacture relies mainly on the extraction form plants. In order to solve the resource shortage, a lot of work has been done to develop the alternative method. Recently, using synthetic biology to realize heterologous biosynthesis of the precursors of taxol has become a hotspot. Now, the basic framework of taxol biosynthetic pathways has been confirmed, and most enzyme genes involved in taxol biosynthesis have been cloned and identified. The two taxol precursors, taxa-4(5),11(12)-diene and taxa-4(20),11(12)-dien-5α-ol, have been synthesized in Escherichia coli and Saccharomyces cerevisiae. Here this paper reviewed the recent advances in the biosynthetic pathway of taxol and the latest developments of synthetic biology, which aims to provide a guidance for the heterologous biosynthesis of taxol.

Since designer cells are attracting much attention as a new modality in gene and cell therapy, it would be advantageous to develop synthetic receptors that recognize artificial ligands and activate solely signaling molecules of interest. In this study, we refined the construction of our previously developed minimal engineered receptors (MERs) to avoid off-target activation of STAT5 while maintaining on-target activation of signaling molecules corresponding to tyrosine motifs. Among the myristoylated, cytoplasmic, and transmembrane types of MERs, the cytoplasmic type had the highest signaling efficiency, although there was off-target activation of STAT5 upon ligand stimulation.

Marine cyclopianes are a family of diterpenoid with novel carbon skeleton and diverse biological activities. Herein, we report our synthetic and chemical proteomics studies of cyclopiane diterpenes which culminate in the asymmetric total synthesis of conidiogenones C, K and 12β-hydroxy conidiogenone C, and identification of Immunity-related GTPase family M protein 1 (IRGM1) as a cellular target. Our asymmetric synthesis commences from Wieland-Miescher ketone and features a sequential intramolecular Pauson-Khand reaction and gold-catalyzed Nazarov cyclization to rapidly construct the 6-5-5-5 tetracyclic skeleton.

Iron is a potent biochemical, and accurate homeostatic control is orchestrated by a network of interacting players at multiple levels. Although our understanding of organismal iron homeostasis has advanced, intracellular iron homeostasis is poorly understood, including coordination between organelles and iron export into the ER/Golgi. Here, we show that SLC39A13 (ZIP13), previously identified as a zinc transporter, promotes intracellular iron transport and reduces intracellular iron levels.

Inflammasomes are defense complexes that utilize cytokines and immunogenic cell death (ICD) to stimulate the immune system against pathogens. Inspired by their dual action, we present cytokine-armed pyroptosis as a strategy for boosting immune response against diverse types of tumors. To induce pyroptosis, we utilize designed tightly regulated gasdermin D variants comprising different pore-forming capabilities and diverse modes of activation, representing a toolbox of ICD inducers.
