Phospholipases in the Response of Fortune Mandarins to Heat and Cold Stress and in the Heat-Induced Cross-Adaption to Chilling

open access: yesHorticulturae
Phospholipases (PLs) are key enzymes involved in membrane remodeling, structure, and signaling during plant stress responses. This study analyzed early and long-term transcriptional regulation of PL isoforms—PLD (CsPLDα,β,δ,γ,ζ), PLA (CsPLA2α,2β, CsPAT1),

Lysophosphatidylcholine stimulates phospholipase D activity in mouse peritoneal macrophages

open access: yesJournal of Lipid Research, 1999
Lysophosphatidylcholine (lysoPC) is a bioactive phospholipid that is involved in atherogenesis and inflammatory processes. However, the present understanding of mechanisms whereby lysophosphatidylcholine exerts its pathophysiological actions is ...

Signaling pathways for transduction of the initial message of the glycocode into cellular responses [PDF]

open access: yes, 1998
The sugar units of glycan structures store information and establish an alphabet of life. The language of the oligosaccharide coding units is deciphered by receptors such as lectins and the decoded message can be transduced by multiple signaling pathways.

Delivery of Pleckstrin‐Homology Domains Suppresses PI3K/Akt Signaling and Breast Cancer Metastasis

open access: yesAdvanced Science, EarlyView.
Current therapies curb tumor growth but not metastasis. Obscurin, a giant metastasis suppressor lost in breast cancer, restrains PI3K/Akt signaling but is impractical to restore. We deploy a mini‐obscurin, comprising the obscurin‐PH‐domain, which sequesters PI3K‐p85, potently suppressing invasion and metastasis.

Effect of post-translational modifications of GM2 activator on phospholipase D activation [PDF]

open access: yes, 2002
G_ activator は, G_ガンダリオシドの代謝酵素である, β-Hexosaminidase A の活性化因子であり, その欠損はG_ gangliosidosis を引き起こす。近年, 当研究室では, G_ activator が, リン脂質の分解酵素であるホスホリパーゼDを活性化することを明らかにした。本研究では, G_ activator の翻訳後修飾が, ホスホリパーゼDの活性化能に及ぼす影響を調べた。翻訳後修飾として, リン酸化および糖鎖の付加を取り上げた。まず ...

Apoptotic signaling through CD95 (Fas/Apo-1) activates an acidic sphingomyelinase. [PDF]

open access: yes, 1994
Intracellular pathways leading from membrane receptor engagement to apoptotic cell death are still poorly characterized. We investigated the intracellular signaling generated after cross-linking of CD95 (Fas/Apo-1 antigen), a broadly expressed cell ...

PVNCRF Neurons Regulate Migraine‐Like Allodynia by Activating CRFR2 on Spinal Trigeminal Caudalis Glutamatergic Neurons

open access: yesAdvanced Science, EarlyView.
Paraventricular CRF neurons in the hypothalamus project to glutamatergic neurons of the spinal trigeminal caudal nucleus, enhancing neuronal activation and CRFR2 signaling. This pathway increases CRF release and excitatory drive, promoting central sensitization and migraine‐related behaviors. Targeting the PVN–SP5C circuit provides a potential strategy

Quantification and Localisation of New Brain Lipid Synthesis Using Deuterium Oxide and High Resolution Mass Spectrometry

open access: yesAngewandte Chemie, EarlyView.
Liquid chromatography tandem mass spectrometry and mass spectrometry imaging were used in combination with deuterium oxide administration to quantify and localise newly synthesised myelin lipids in the mouse brain. This methodology, used here to show sites of myelin repair, enables the measurement of dynamic lipid synthesis in living systems and ...

Thyroxine signal transduction in liver cells involves phospholipase C and phospholipase D activation. Genomic independent action of thyroid hormone

open access: yesBMC Cell Biology, 2001
Background Numerous investigations demonstrate a novel role of thyroid hormone as a modulator of signal transduction. Protein kinase C (PKC) is critical to the mechanism by which thyroid hormones potentiate both the antiviral and immunomodulatory actions

Endoplasmic Reticulum Geometry Dictates Neuronal Bursting via Calcium Store Refill Rates and Exposes Selective Neuronal Vulnerability

open access: yesAdvanced Science, EarlyView.
The ER's continuous tubular network is maintained by ER‐shaping proteins whose mutation or dysregulation contributes to neurodegenerative diseases. Here, we show that ER morphology sets the speed of Ca2+ store replenishment between firing events. Disrupting ER continuity slows intra‐ER Ca2+ redistribution from extracellular refill (SOCE) sites, driving
