Rhizobacteria‐Induced Systemic Priming Against Fungal Pathogens Involves Hydroxycinnamic Acid Amides

Plant, Cell &Environment, EarlyView.
ABSTRACT The rhizosphere, a narrow region of soil surrounding roots, contains diverse microorganisms with a composition that is distinct from the surrounding soil. Some rhizosphere bacteria can trigger a heightened state of immunity in the whole plant, termed Induced Systemic Resistance (ISR).

Circular RNAs in Lotus japonicus Responses to Nutrient Supply and Mesorhizobium Symbiosis

Plant, Cell &Environment, EarlyView.
ABSTRACT Symbiotic interactions between legumes and rhizobia enable nitrogen fixation under low nutrient conditions. The establishment and function of symbiotic interactions require coordinated changes in gene expression in both the host and the microbe. Circular RNAs (circRNAs) are endogenous gene‐specific molecules that can regulate transcription and

Regulating T-cell differentiation through the polyamine spermidine

, 2020
Background The cross-talk between the host and its microbiota plays a key role in the promotion of health. The production of metabolites such as polyamines by intestinal-resident bacteria is part of this symbiosis shaping host immunity.

Unveiling contrasting iron efficiency strategies in common bean (Phaseolus vulgaris L.) genotypes under iron deficiency

Plant Biology, EarlyView.
Common bean genotypes differ in their iron acquisition through distinct Strategy I responses and root exudation patterns. Abstract Iron (Fe) deficiency in food crops, particularly on calcareous soils, limits productivity and human nutrition. This study investigated two common bean (Phaseolus vulgaris) genotypes, Guaymí (high Fe‐accumulating, HI) and ...

Dietary interventions in acute kidney injury: From molecular mechanism to clinical trials

Experimental Physiology, EarlyView.
Abstract Ageing impairs renal resilience with an elevated risk of frequent and harmful acute kidney injury (AKI) that causes substantial morbidity and mortality among hospitalized patients. Since different damaging stimuli at the molecular, cellular and functional level contribute to this loss in kidney function, AKI's pathophysiology is heterogeneous ...

Characteristics of spermidine uptake by isolated rat enterocytes

, 1989
Eukaryotic cells require polyamines for growth. The supply of polyamines to growing cells may be increased either by new synthesis or increased uptake.

Spermidine-induced macrophage reprogramming for liver fibrosis treatment

, 2023
Liver fibrosis can be regarded as an aberrant wound-healing process in response to chronic hepatic injury, which is characterized by extracellular matrix deposition leading to the generation of the fibrous scar and subsequent hepatic dysfunction ...

Spermidine Enhances Mitochondrial Bioenergetics in Young and Aged Human-Induced Pluripotent Stem Cell-Derived Neurons

Antioxidants
The accumulation of damaged mitochondria has long been considered a hallmark of the aging process. Among various factors, age-related mitochondrial alterations comprise bioenergetic impairments and disturbances in reactive oxygen species (ROS) control ...

Skeletal muscle‐specific myostatin overexpression promotes muscle oxidative capacity and fatigue resistance in transgenic mice

Experimental Physiology, EarlyView.
Abstract In addition to controlling muscle mass, myostatin may support oxidative metabolism and endurance. Loss of function through gene knockout or post‐natal blockade generally lowers muscle oxidative capacity and increases fatigability. These observations imply that myostatin activation could promote a more oxidative and less fatigable muscle ...

Mechanisms of spermidine-induced autophagy and geroprotection

, 2022
Aging involves the systemic deterioration of all known cell types in most eukaryotes. Several recently discovered compounds that extend the healthspan and lifespan of model organisms decelerate pathways that govern the aging process.
