Hyperactivation and Tyrosine Phosphorylation of Cryopreserved Stallion Spermatozoa in Relation to Conventional In Vitro Fertilization Blastocyst Production

Andrology, EarlyView.
ABSTRACT Background Challenges in establishing clinical conventional in vitro fertilization (IVF) in horses include variation in sperm and oocyte quality, which can be affected by mare age. Extended preincubation of stallion spermatozoa has resulted in successful IVF.

PDE4D and PDE3B orchestrate distinct cAMP microdomains in 3T3‐L1 adipocytes

British Journal of Pharmacology, EarlyView.
Basal conditions: •Ins/PDE3B lowers cytoplasmic cAMP (cyt‐cAMP) without affecting plasma membrane cAMP (pm‐cAMP). •Insulin decreases lipid droplet cAMP (LD‐cAMP) independent of PDE3B. •FGF1/PDE4D modestly reduces both cyt‐ and pm‐cAMP, while PDE4D alone can modulate LD‐cAMP. ISO stimulation: •Ins/PDE3B has minimal impact on cyt‐cAMP.

Serum Lipidomics Profiling Identify Novel Biomarkers of Distal Symmetrical Polyneuropathy in Type 1 Diabetes

Diabetes, Obesity and Metabolism, EarlyView.
ABSTRACT Background Distal symmetrical polyneuropathy (DSPN) is a common complication of type 1 diabetes (T1D), yet validated biomarkers for early detection or prognosis are lacking. Metabolic disturbances driven by chronic hyperglycemia and dyslipidemia contribute to DSPN development and progression.

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

The 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).

The sorting nexin Snx21 promotes flotillin‐mediated endocytosis

The FEBS Journal, EarlyView.
In this study, we describe a novel function of the previously uncharacterized Snx21 protein as a specific positive regulator of flotillin‐mediated endocytic trafficking. Snx21 is recruited to endosomal membranes via binding to PI(3)P, and it colocalizes with flotillins on the surface of late endosomes.

CD36‐mediated lipid rewiring in the metabolic adaptation of tumour ecosystems

The FEBS Journal, EarlyView.
Nutrient deprivation drives a lipid‐centric shift in tumour metabolic symbiosis and signalling network. CD36 functions as a bidirectional bridge, transferring fatty acids from stromal donors (adipocytes, CAFs) to the ecosystem tumour‐ and microenvironment‐dependently.

Metabolic Profiling of Circulating and Tumour‐Infiltrating T Cells Uncovers Bioenergetic Checkpoints Linked With Immune and Clinical Skewing in Melanoma Patients

Immunology, EarlyView.
In this study, we revealed the disturbed metabolic status of circulating and tumour‐infiltrating CD4+ and CD8+ T cells in melanoma patients through targeted metabolomic and lipidomic (on sorted subsets) and at single cell level using the SCENITH method.

Myo1g Mediates NKR‐P1C Expression in Primary Mouse NK Cells and Participates in Cytotoxicity

Immunology, EarlyView.
In this study we analysed the participation of Myosin 1g in the development and functions of murine natural killer (NK) cells; we found that Myosin 1g is expressed in murine‐activated primary NK cells from the spleen. Additionally, in the absence of Myosin 1g, correlates with a reduced expression of NKR‐P1C but not of CD49b or NKp46.

Systemic Lipidomics Identifies Altered Ceramide–Phospholipid Balance Associated With Periodontitis Severity: A Cross‐Sectional Study With 12‐Year Follow‐Up

Journal of Clinical Periodontology, EarlyView.
ABSTRACT Aim To investigate whether periodontitis stage and grade are associated with circulating active lipid mediators and whether baseline lipid species predict periodontitis progression. Materials and Methods The study included 473 Finnish participants from the Parogene cohort undergoing coronary angiography, with 12‐year follow‐up data available ...
