The conversion of natural wetlands to paddy fields affects net ecosystem carbon fluxes by restructuring the coupling between soil microbial communities and physicochemical properties

Ecological Processes
Background Natural wetlands serve as important global carbon sinks and play a critical role in regulating greenhouse gas emissions. However, the widespread conversion of wetlands into paddy fields has raised concerns, and its impacts on ecosystem net ...

A function-based typology for Earth’s ecosystems

Nature, 2022
AbstractAs the United Nations develops a post-2020 global biodiversity framework for the Convention on Biological Diversity, attention is focusing on how new goals and targets for ecosystem conservation might serve its vision of ‘living in harmony with nature’1,2.

Microbiome−host proteostasis crosstalk—An emerging perspective on mechanisms and interventions toward healthy longevity

FEBS Letters, EarlyView.
Proteostasis and the gut microbiota play a key role in shaping host physiology. Microbiota‐derived metabolites, vitamins, and RNA modulate host proteostasis. Findings from model systems, including C. elegans, indicate microbes can either stabilize or disrupt host proteostasis.

Shorebirds Affect Ecosystem Functioning on an Intertidal Mudflat

Frontiers in Marine Science, 2020
Ecosystem functioning and services have provided a rationale for conservation over the past decades. Intertidal muddy sediments, and the microphytobenthic biofilms that inhabit them, perform crucial ecosystem functions including erosion protection ...

From atoms to ecosystems: elementome diversity meets ecosystem functioning [PDF]

New Phytologist, 2021
SummaryThe elemental composition of plants (the elementome) is a reliable indicator of their functional traits and the ecological strategies that they follow, and thus represents a good predictor of how ecosystems work. Biodiversity and, especially, functional diversity are also widely recognized as important drivers of ecosystem functioning, mainly ...

Epigenetic reprogramming of lineage switching in cancer

FEBS Letters, EarlyView.
Cancer cells rarely commit to a single identity. Epigenetic mechanisms and tumor microenvironment cues push epithelial cells toward flexible, hybrid states that can shift into mesenchymal, neuroendocrine, or stem‐like fates, driving metastasis, drug resistance, and tumor heterogeneity. Targeting the epigenetic regulators behind these transitions, using

Lipid droplets sequester palmitic acid to disrupt endothelial ciliation and exacerbate atherosclerosis in male mice

Nature Communications
Disruption of ciliary homeostasis in vascular endothelial cells has been implicated in the development of atherosclerosis. However, the molecular basis for the regulation of endothelial cilia during atherosclerosis remains poorly understood.

Structural and biochemical analysis of a B12 superbinder

FEBS Letters, EarlyView.
BtuG proteins are vitamin B12 scavengers in Bacteroides thetaiotaomicron, a dominant human gut bacterium. We present crystal structures of three BtuG homologs bound to cobalamin and its precursor cobinamide, revealing picomolar binding affinities, among the highest known for any natural protein.
