Tau acetylation at K331 has limited impact on tau pathology in vivo

FEBS Letters, EarlyView.
We mapped tau post‐translational modifications in humanized MAPT knock‐in mice and in amyloid‐bearing double knock‐in mice. Acetylation within the repeat domain, particularly around K331, showed modest increases under amyloid pathology. To test functional relevance, we generated MAPTK331Q knock‐in mice.

Intercropping Between Panax ginseng and Arisaema amurense Improves Ginseng Quality by Improving Soil Properties and Microbial Communities

Horticulturae
The imbalance in soil microcosm systems caused by the long-term monoculture of ginseng is the main cause of continuous cropping disorder in ginseng, an important factor limiting the development of the ginseng industry.

Epigenetic blind spots – the role of DNA methylation dynamics in stem cell‐based models of embryogenesis

FEBS Letters, EarlyView.
Embryo‐like structures (stembryos) are an innovative tool, but they are hindered by experimental variability and limited developmental potential. DNA methylation is crucial for mammalian development, but its status in stembryo models is poorly characterized.

Metabolomics combined with physiology and transcriptomics reveals key metabolic pathway responses in ginseng roots to nitrogen and potassium deficiency

Plant Stress
Nitrogen (N) and potassium (K) are essential macronutrients for plant growth and development; however, the molecular mechanisms underlying their synergistic regulation of secondary metabolism in medicinal plants remain elusive.

An unexpected alternative viologen electron mediator site in tungsten‐containing formate dehydrogenase

FEBS Letters, EarlyView.
An unexpected alternative interaction site for ethyl viologen was identified in formate dehydrogenase 1 from Methylorubrum extorquens. Combined mutagenesis, kinetic analysis, and docking revealed that aromatic residues near an iron–sulfur cluster enable flavin mononucleotide‐independent electron transfer, offering a framework for engineering improved ...

Preliminary Phytochemical Analysis and Antioxidant, Antibacterial Activities of Crocus alatavicus from Kazakhstan

Notulae Botanicae Horti Agrobotanici Cluj-Napoca, 2015
Phytochemical analysis of C. alatavicus revealed the presence of phenols, flavonoids, anthocyanins, carotenoids, amino acids and carbohydrates. The flavonoid, amino acids and carotenoid contents were higher in aerial part (1.50%, 7.49% and 9.78mg ...
