[Advances in paclitaxel biosynthesis and transcriptional regulation mechanisms]

Abstract

Paclitaxel, a rare diterpene extracted from the bark of Chinese yew (Taxus chinensis), is renowned for its anti-cancer activity and serves as a primary drug for treating cancers. Due to the exceptionally low content of paclitaxel in the bark, a semi-synthetic method that depletes Chinese yew resources is used in the production of paclitaxel, which, however, fails to meet the escalating clinical demand. In recent years, researchers have achieved significant progress in heterologous biosynthesis and metabolic engineering for the production of paclitaxel. This article comprehensively reviews the advancements in paclitaxel production, encompassing chemical synthesis, heterologous biosynthesis, and cell engineering. It provides an in-depth introduction to the biosynthetic pathway and transcriptional regulation mechanisms of paclitaxel, aiming to provide a valuable reference for further research on paclitaxel biosynthesis.
