Physapubescin B From Physalis: A Food‐Derived Withanolide for Cancer Chemoprevention and Nutraceutical Development

open access: yeseFood, Volume 7, Issue 4, August 2026.
Physapubescin B may interfere with multiple cancer‐associated signaling pathways by inhibiting Ras/Raf/mitogen‐activated protein kinase kinase/extracellular signal‐regulated kinase (Ras/Raf/MEK/ERK) signaling and vascular endothelial growth factor (VEGF)‐dependent angiogenesis.

The Epigenetic Regulation in Plant Specialized Metabolism: DNA Methylation Limits Paclitaxel in vitro Biotechnological Production

open access: yesFrontiers in Plant Science, 2022
Environmental conditions are key factors in the modulation of the epigenetic mechanisms regulating gene expression in plants. Specifically, the maintenance of cell cultures in optimal in vitro conditions alters methylation patterns and, consequently ...

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

open access: yesMolecular 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.

Biotransormations with plant coenzyme A-dependent acyltransferases [PDF]

open access: yes, 2008
The acylation of plant natural products is widely observed in nature and this modification often confers novel bioactivities. In nature, each of these acylations is selectively catalysed by a coenzyme A-dependent acyltransferase and biotransformations ...

Selection and validation of reference genes for quantitative gene expression normalization in Taxus spp.

open access: yesScientific Reports, 2020
Quantitative real-time PCR (qRT-PCR) is commonly used to measure gene expression to further explore gene function, while suitable reference genes must be stably expressed under different experimental conditions to obtain accurate and reproducible data ...

Taxol biosynthesis: Taxane 13α-hydroxylase is a cytochrome P450-dependent monooxygenase [PDF]

open access: yesProceedings of the National Academy of Sciences, 2001
A central feature in the biosynthesis of Taxol is oxygenation at multiple positions of the taxane core structure, reactions that are considered to be mediated by cytochrome P450-dependent monooxygenases. A PCR-based differential display-cloning approach, usingTaxus(yew) cells induced for Taxol production, yielded a family of related cytochrome P450 ...

Vacuolization as a Novel Approach to Cancer Therapy

open access: yesJournal 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

open access: yesFood 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 ...
