Studies on the biosynthesis of taxol: the taxane carbon skeleton is not of mevalonoid origin. [PDF]

Proceedings of the National Academy of Sciences, 1996
A cell culture of Taxus chinensis was established to produce the diterpene 2alpha,5alpha,10beta,14beta-tetra-acetoxy4 ++ +(20),11-taxadiene (taxuyunnanine C) in 2.6% (dry weight) yield. The incorporation of [U-13C6]glucose, [1-13C]glucose, and [1,2-13C2]acetate into this diterpene was analyzed by NMR spectroscopy.

Hippo pathway at the crossroads of stemness and therapeutic resistance in breast cancer

Molecular Oncology, Volume 20, Issue 7, Page 1667-1693, July 2026.
Dysregulation of the Hippo pathway drives nuclear accumulation of YAP/TAZ, activating stemness‐related transcriptional programs that sustain breast cancer stemness and fuel therapeutic resistance across subtypes, underscoring Hippo signaling as a targetable vulnerability. Figure created and edited with BioRender.com.

Transcriptome-wide identification and screening of WRKY factors involved in the regulation of taxol biosynthesis in Taxus chinensis

, 2018
WRKY, a plant-specific transcription factor family, plays important roles in pathogen defense, abiotic cues, phytohormone signaling, and regulation of plant secondary metabolism. However, little is known about the roles, functions, and mechanisms of WRKY

Vacuolization as a Novel Approach to Cancer Therapy

Journal of Biochemical and Molecular Toxicology, Volume 40, Issue 6, June 2026.
This review discusses the novel strategy of inducing vacuole formation in cancer cells using small molecules, that induce nonapoptotic cell death mechanisms, such as paraptosis, oncosis, autophagy, and methuosis, and its potential in overcoming resistance to apoptosis‐based cancer therapies.

Homoisoflavonoids—From Natural Specificity and Biosynthesis to Precision Health‐Promoting Mechanisms

Food Frontiers, Volume 7, Issue 3, May 2026.
Homoisoflavonoids are rare flavonoids with a unique bi‐aromatic oxygen‐heterocyclic structure. This review synthesizes their structure–activity relationships in anti‐inflammatory, hypoglycemic, and anticancer contexts. By highlighting their specific natural distribution and outlining biosynthetic pathways, it provides a conceptual framework and ...

Mass Spectrometry Imaging Combined With Single‐Cell Transcriptional Profiling Reveals the Multidimensional Spatial Distributions and Biosynthetic Pathways of Medicinal Components in Andrographis paniculata

Plant Biotechnology Journal, Volume 24, Issue 5, Page 2876-2890, May 2026.
ABSTRACT The synthesis and accumulation of active ingredients in medicinal plants are distributed in specific organs, tissues, and cell types, which are important for the exploitation of medicinal plants. However, the fine distribution of active ingredients is difficult to know. Here, the system of mass spectrometry imaging (MSI) integrated with single‐

Enantioselective Total Synthesis of (−)-Taxol

, 2016
Enantioselective total synthesis of taxol has been accomplished. Coupling reaction of the optically pure A-ring hydroxy aldehyde with the aromatic C-ring fragment followed by Lewis acid mediated eight-membered B-ring cyclization gave the desired ABC endo-

Engineering of 10‐Deacetylbaccatin III‐10‐β‐O‐Acetyltransferase From Taxus Species for Efficient Acetylating Non‐Natural Substrates Into Taxol in Nicotiana benthamiana

Plant Biotechnology Journal, Volume 24, Issue 5, Page 3308-3323, May 2026.
ABSTRACT 7‐β‐xylosyl‐10‐deacetyltaxol (XDT) is much more abundant than the anticancer drug Taxol in Taxus species and is usually regarded as the by‐product of Taxol. It could be enzymatically transformed into 10‐deacetyltaxol (DT), and the latter could be further converted into Taxol.
