SMILE: Extraction‐free submicron‐resolution mapping of lipid chain length and unsaturation by stimulated Raman imaging

open access: yesVIEW, EarlyView.
In this work, we develop submicron‐resolution mapping of intracellular lipid elements (SMILE) as an extraction‐free vibrational spectroscopic imaging platform based on hyperspectral stimulated Raman scattering microscopy with a spectral analysis pipeline for pixel‐resolved lipid profiling.

Comparison of Three Sympatric Desert Lizards: Digestive Tract Structure, Digestive Enzyme Activities, Gut Microbiota, and Metabolites

open access: yesIntegrative Zoology, EarlyView.
We performed 16S rDNA sequencing and metabolite profiling for three sympatric lizard species—Teratoscincus roborowskii, Phrynocephalus axillaris, and Eremias roborowskii—and compared their goblet cell and enzyme activities in the digestive tract. Our study suggests that the dietary niche may promote divergence or convergence of microbiota across host ...

Kaempferol Protects Intestinal Health in Chinese Forest Musk Deer Possibly by Regulating Intestinal Microbiota and Inhibiting the NF‐κB/NLRP3 Signaling Pathway

open access: yesIntegrative Zoology, EarlyView.
Kaempferol modulates the tryptophan metabolism pathway by increasing the abundances of Christensenellaceae R7 group, Bacteroides, and Blautia and reducing that of Rikenellaceae RC9 gut group, thereby significantly increasing the levels of ILA and IAA. This process inhibits the activation of NF‐κB/NLRP3 signaling pathway, reduces pro‐inflammatory factor

Amyloid‐β aggregates induce vasculopathy via ferroptosis in brain endothelial cells

open access: yesBrain Pathology, EarlyView.
Blood–brain barrier (BBB) disruption is evident in brains with amyloidopathy. In this study, we demonstrate that amyloid β (Aβ) drives abnormal lipid metabolism and lipid droplet formation in brain endothelial cells, leading to lipid peroxidation and ferroptosis.

LPC18:0 Secreted by Exogenous Neural Stem Cells Potentiates Neurogenesis and Functional Recovery via GPR55‐Mediated Signalling in Spinal Cord Injury

open access: yesCell Proliferation, EarlyView.
LPC18:0 secreted by exogenous neural stem cells potentiates neurogenesis via the GPR55/AKT/GSK3β signalling axis, which ultimately promotes spinal cord injury recovery. ABSTRACT Spinal cord injury (SCI) is a devastating condition with limited therapeutic options. Although neural stem cell (NSC) transplantation shows regenerative potential, its efficacy

Targeting Egfr‐Mediated Cell Proliferation and Lipid Metabolism Separation Effectively Accelerate Liver Regeneration

open access: yesCell Proliferation, EarlyView.
AREG coordinates cell proliferation and lipid metabolism reprogramming during liver regeneration and targeting lipid metabolism can promote liver regeneration. ABSTRACT Hepatocyte proliferation restores liver mass after partial hepatectomy (PHx), but the metabolic cost of this process remains unclear.

Multiparasitism Resolves the Apparent Paradox of High Male Pheromone Investment Despite Frequent Within‐Host Mating in a Parasitoid

open access: yesEntomologia Experimentalis et Applicata, EarlyView.
It is unknown why males of the parasitoid wasp Nasonia giraulti produce large amounts of a costly sex pheromone although they were long thought to mate with their females already before emergence within the host. Mated females do no longer respond to the pheromone.

Steroidogenic compensation and lipid deficiency with enhanced NAD+ salvage in small‐for‐gestational‐age placenta

open access: yesThe FEBS Journal, EarlyView.
Fetal growth restriction is associated with placental metabolic adaptations. In small‐for‐gestational‐age placenta (SGA), cholesterol receptors and steroidogenic enzymes are upregulated, enhancing steroidogenesis. NAD salvage pathway is also increased to support NADP+/NADPH requirements.

1H NMR metabolomics and lipidomics analysis of neutrophils reveals biomarkers of ageing, inflammageing and frailty

open access: yesThe FEBS Journal, EarlyView.
Using 1H NMR metabolomics, we measured polar and lipid metabolites from human blood neutrophils from people with frailty (n = 31, mean age 84Y), people with rheumatoid arthritis (n = 16, mean age 55Y), robust older (n = 24, mean age 66Y) and healthy younger people (n = 21, mean age 22Y).

Investigation into the delivery and evaluation of a unique Avena sativa (Oat) Lipid Extract on skin barrier using LC‒MS/MS, Raman spectroscopy, immunostaining analysis and skin efficacy

open access: yesInternational Journal of Cosmetic Science, EarlyView.
Abstract Objectives Oat lipids are rich in ceramides. In this investigation, we analysed the delivery of a specific Oat Lipid Extract derived from Avena sativa, comprising ‘skin identical’ ratios of fatty acids, ceramides and cholesterol/sterol. This investigation is the first reported investigation of oat lipids utilizing Raman spectroscopy for the ...
