The co-treatment of metformin with flavone synergistically induces apoptosis through inhibition of PI3K/AKT pathway in breast cancer cells.

Oncology Letters, 2018
Metformin, a widely used antidiabetic drug, exhibits anticancer effects which are mediated by the phosphatidylinositol 3-kinase (PI3K)/serine/threonine kinase (AKT) signaling pathway.

Metabolo‐Transcriptomics Analyses Reveal Alfalfa Adaptation to Combined Saline‐Alkali and Low‐Temperature Stress in the Field

Plant Biotechnology Journal, EarlyView.
ABSTRACT Alfalfa (Medicago sativa L.) is known as the ‘King of Forage’ because of its high protein content and excellent palatability. Alfalfa productivity is adversely affected in cold regions with saline‐alkali soils. However, the mechanisms underlying the response of alfalfa to combined saline‐alkali and low‐temperature stress under field conditions

OsSTK‐Mediated Sakuranetin Biosynthesis and Carbon Flux Orchestrate Growth and Defence in Rice

Plant Biotechnology Journal, EarlyView.
ABSTRACT Plants balance resource energy allocation between growth and immunity to ensure survival and reproduction under limited availability. This study reveals that rice cultivars with elevated sucrose levels boost resistance to the fungal pathogen Magnaporthe oryzae by accumulating the phytoalexin sakuranetin, regulated by the transcription factor ...

Novel 2-amino-isoflavones exhibit aryl hydrocarbon receptor agonist or antagonist activity in a species/cell-specific context [PDF]

, 2012
The aryl hydrocarbon receptor (AhR) mediates the induction of a variety of xenobiotic metabolism genes. Activation of the AhR occurs through binding to a group of structurally diverse compounds, most notably dioxins, which are exogenous ligands ...
