On the miRNAs-regulated mechanisms by which natural plant polysaccharides control apoptosis

Pharmacological Research - Modern Chinese Medicine
Instruction: Plant polysaccharides are important components of Chinese herbal medicine. Many polysaccharides, such as Astragalus polysaccharide and Lycium barbarum polysaccharide, have important functions such as tumor growth inhibition, antioxidant ...

Salmonella lipopolysaccharide‐containing supported lipid bilayers as platforms to study bacteriophage interactions

FEBS Letters, EarlyView.
We present robust protocols for the preparation of supported lipid bilayers (SLBs) incorporating either Salmonella smooth LPS or outer membrane vesicles (OMVs). We use a combination of quartz crystal microbalance with dissipation (QCM‐D) and fluorescence microscopy to both characterize the SLBs of various compositions and to probe their interactions ...

Structural insights and therapeutic targets in Acinetobacter baumannii capsule biosynthesis

FEBS Letters, EarlyView.
Hypervirulent KL49 A. baumannii's capsular polysaccharide contains the nonulosonic acid 8‐epi‐Leg5,7Ac2, synthesized by epimerization via ElaA, ElaB, and ElaC. Crystal structures of ElaA, ElaB, and ElaC reveal their role in CMP‐Leg5,7Ac2 synthesis and regioselective C8 epimerization.

Anti-Cancerous Potential of Polysaccharides Derived from Wheat Cell Culture

Pharmaceutics, 2022
There is a global need to discover effective anti-cancerous compounds from natural sources. Cultivated wheat cells can be a valuable source of non-toxic or low toxic plant-derived polysaccharides.

Tumour–host interactions in Drosophila: mechanisms in the tumour micro‐ and macroenvironment

Molecular Oncology, EarlyView.
This review examines how tumour–host crosstalk takes place at multiple levels of biological organisation, from local cell competition and immune crosstalk to organism‐wide metabolic and physiological collapse. Here, we integrate findings from Drosophila melanogaster studies that reveal conserved mechanisms through which tumours hijack host systems to ...

A yeast model of 5‐oxoproline accumulation reveals a general toleration to 5‐oxoproline

FEBS Open Bio, EarlyView.
Using a yeast model, we show that even high accumulation of 5‐oxoproline causes only mild cellular stress and does not trigger oxidative stress. Instead, cells adapt by activating efflux pumps and diverse protective pathways, suggesting that previously proposed harmful effects of 5‐oxoproline may arise from indirect metabolic imbalances rather than the

Research progress on preparation and characteristics of polysaccharide plant protein complex

Shipin yu jixie
Polysaccharides and proteins are two important components in food. Combining plant protein with polysaccharides can give full play to their advantages, show new functional characteristics, and improve their shortcomings.

O-Acetylation of Plant Cell Wall Polysaccharides [PDF]

Frontiers in Plant Science, 2012
Les parois des cellules végétales sont composées de polymères structurellement divers, dont beaucoup sont O-acétylés. Comment les plantes O-acétylent les polymères pariétaux et quelle est leur fonction sont restées insaisissables jusqu'à récemment, lorsque deux familles de protéines ont été identifiées dans la plante modèle Arabidopsis qui sont ...

Evaluating the effect of γ‐oryzanol on MASLD pathology using a medaka fish model

FEBS Open Bio, EarlyView.
This study explores a liver disease called MASLD, which is increasing worldwide and can lead to serious damage. Researchers used medaka fish instead of rodents to test a food compound, γ‐oryzanol. Fish fed this compound had less liver fat and healthier gut bacteria.
