Metabolic Modulation Predicts Heart Failure Tests Performance [PDF]

, 2019
The metabolic changes that accompany changes in Cardiopulmonary testing (CPET) and heart failure biomarkers (HFbio) are not well known. We undertook metabolomic and lipidomic phenotyping of a cohort of heart failure (HF) patients and utilized Multiple ...

PAIR: Reconstructing Single‐Cell Open‐Chromatin Landscapes for Transcription Factor Regulome Mapping

Advanced Science, EarlyView.
scATAC‐seq analysis is often constrained by limited sequencing depth, extreme sparsity, and pervasive technical missingness. PAIR is a probabilistic framework that restores scATAC‐seq accessibility profiles by directly modeling the native cell–peak bipartite structure of chromatin accessibility.

Secreted Nonstructural Protein 3 is a Pathogenic Determinant of Orbivirus

Advanced Science, EarlyView.
This study uncovers a conserved PIP2‐dependent secretory pathway of orbivirus NS3 that induces vascular leakage. Pharmacological disruption of PIP2‐NS3 interaction significantly reduces viral pathogenicity and provides protective efficacy in murine models, establishing PIP2‐mediated NS3 secretion as both a key virulence determinant and a promising ...

WTAP‐Mediated m6A Modification Targets the LRP1‐Lipid Metabolism Axis to Regulate Joint Cartilage Regeneration

Advanced Science, EarlyView.
WTAP drives cartilage regeneration by activating an LRP1‐dependent lipid metabolic program in macrophages, enhancing IL‐10 and TGF‐β secretion to promote chondrogenic differentiation. Leveraging this mechanism, virtual screening identifies LRP1‐targeting compounds that effectively stimulate cartilage repair, highlighting a druggable epigenetic ...

Preparation, Component Identification, and Antioxidant Activity of Anthocyanins From Punica granatum “Tunisia”

AgriFood: Journal of Agricultural Products for Food, EarlyView.
The preparation for Tunisian pomegranate anthocyanin extract. The molecular mechanisms underlying the antioxidant effects of these compounds were investigated using network pharmacology and molecular docking. Antioxidant activity was evaluated through DPPH, ABTS, and FRAP assays, whereas the effects on oxidative stress and inflammation were examined in

GhFAD3-4 Promotes Fiber Cell Elongation and Cell Wall Thickness by Increasing PI and IP₃ Accumulation in Cotton

Plants
The omega-3 fatty acid desaturase enzyme gene FAD3 is responsible for converting linoleic acid to linolenic acid in plant fatty acid synthesis. Despite limited knowledge of its role in cotton growth, our study focused on GhFAD3-4, a gene within the FAD3 ...

Chemical Synthesis of 6-Azido-6-Deoxy Derivatives of Phosphatidylinositol Containing Different Fatty Acid Chains

Molecules
This paper describes the synthesis of two 6-azido-6-deoxy derivatives of phosphatidylinositol (PI), which contained different fatty acid chains. These syntheses, starting from methyl α-d-glucopyranoside, employed multiple regioselective transformations ...

Simultaneous inhibition of pan-phosphatidylinositol-3-kinases and MEK as a potential therapeutic strategy in peripheral T-cell lymphomas

Haematologica, 2013
Peripheral T-cell lymphomas are very aggressive hematologic malignancies for which there is no targeted therapy. New, rational approaches are necessary to improve the very poor outcome in these patients.
