A new, long-wavelength borondipyrromethene sphingosine for studying sphingolipid dynamics in live cells[S]

open access: yesJournal of Lipid Research, 2013
Sphingolipids function as cell membrane components and as signaling molecules that regulate critical cellular processes. To study unacylated and acylated sphingolipids in cells with fluorescence microscopy, the fluorophore in the analog must be located ...

Sphingolipids in Major Depression

open access: yesNeurosignals, 2015
Major depression is one of the most common and severe diseases affecting the world's population. However, the pathogenesis of the disease remains inadequately defined. Previously, a lack of monoaminergic neurotransmitters was the focus of pathophysiological concepts; however, recent concepts focus on a alteration of neurogenesis in the hippocampus ...

Drought Stress Mediated Changes in Food Crops: Mechanisms and Remediation Strategies

open access: yesAdvanced Science, EarlyView.
This work presents a multi‐scale framework for flavonoid‐mediated drought tolerance in staple food crops, integrating ROS redox regulation, antioxidant defense, rhizosphere microbial interactions, and sustainable agronomic practices. This interdisciplinary model provides core insights to develop climate‐resilient cropping systems and enhance global ...

ACSL4‐Dependent Lysosomal Lipid Peroxidation Links WTAP‐Mediated m6A Modification to Intervertebral Disc Degeneration

open access: yesAdvanced Science, EarlyView.
IL‐1β upregulates the protein level of WTAP, which promotes the m6A modification of ACSL4 mRNA in an IGF2BP2‐dependent manner, thereby enhancing its stability. The increased ACSL4 drives lipid peroxidation, leading to lysosomal membrane permeabilization (LMP) and impaired mitophagy, which collectively accelerate intervertebral disc degeneration (IVDD).

Functional roles of sphingolipids in immunity and their implication in disease

open access: yesExperimental and Molecular Medicine, 2023
Sphingolipids, which are components of cellular membranes and organ tissues, can be synthesized or degraded to modulate cellular responses according to environmental cues, and the balance among the different sphingolipids is important for directing ...

The Cancer Cell Metabolic Reprogramming Remodels the Tumor Microenvironment: Molecular Mechanisms and Therapeutic Strategies

open access: yesAdvanced Science, EarlyView.
This review elucidates how cancer cell metabolic reprogramming—across glucose, lipid, amino acid, and nucleotide pathways—remodels the tumor microenvironment to suppress anti‐tumor immunity and promote immune escape. Targeting these metabolic axes offers promising strategies to overcome immunotherapy resistance and enhance cancer treatment.

Multifunctional Nanovaccine‐Radiotherapy Synergy Drives Anti‐Tumor Immunity via Multi‐Cascade Cell Death for Pancreatic Cancer Therapy

open access: yesAdvanced Science, EarlyView.
Machine‐learning‐driven transcriptomic analysis identifies FSTL3 as a key tumor‐microenvironment regulator in desmoplastic pancreatic adenocarcinoma. A cRGD‐modified liposome co‐loading gemcitabine and siFSTL3 serves as an irradiation‐triggered in situ nanovaccine. It synergizes with radiotherapy to induce ferroptosis and immunogenic cell death through

Sphingolipids and plant defense/disease: the "death" connection and beyond

open access: yesFrontiers in Plant Science, 2012
Sphingolipids comprise a major class of structural materials and lipid signaling molecules in all eukaryotic cells. Over the past two decades, there has been a phenomenal growth in the study of sphingolipids (i.e.

Sphingolipids in apoptosis.

open access: yesExperimental oncology, 2013
Forty years ago, the term "apoptosis" was introduced to describe a form of programmed cell death. Key players that mediate apoptosis at the molecular level such as caspases, death receptors, Bcl-2 family members have since been identified and their regulation remains a research focus of many laboratories.
