Binding of inositol phosphates to arrestin [PDF]

open access: yesFEBS Letters, 1991
Arrestin binds to phosphorylated rhodopsin in its light‐activated form (metarhodopsin II), blocking thereby its interaction with the G‐protein, transducin. In this study, we show that highly phosphorylated forms of inositol compete against the arrestin‐rhodopsin interaction.

Decoding Undesirable Inflammatory Responses of Nucleic Acid‐Delivering Lipid Nanoparticles

open access: yesAdvanced Science, EarlyView.
Lipid nanoparticles (LNPs) enable efficient nucleic acid delivery, but their immunogenicity is a double‐edged sword. This review explores LNP‐driven innate and adaptive immunity, covering lipid components, endosomal escape, and nucleic acid sensing.

Thrombin-induced events in non-platelet cells are mediated by the unique proteolytic mechanism established for the cloned platelet thrombin receptor. [PDF]

open access: yes, 1992
We recently isolated a cDNA clone encoding a functional platelet thrombin receptor that defined a unique mechanism of receptor activation. Thrombin cleaves its receptor's extracellular amino terminal extension, unmasking a new amino terminus that ...

Transcriptomic validation of a 7,12 Dimethylbenz(a)anthracene (DMBA)‐induced leukemia rat model: Parallels with human leukemogenesis

open access: yesAnimal Models and Experimental Medicine, EarlyView.
7,12‐Dimethylbenz[a]anthracene (DMBA) could induce leukemia and other types of cancers in rat models. Transcriptomics revealed gene expression profile that parallels with human leukemia. DMBA‐induced differential gene expression could validate the developed rat model.

Activation of phospholipase C beta4 by heterotrimeric GTP-binding proteins [PDF]

open access: yes, 1994
Transient transfection assays were used to determine how the activity of phospholipase C beta 4, which is preferentially expressed in retina, was regulated.

Label-free shotgun proteomics and metabolite analysis reveal a significant metabolic shift during citrus fruit development. [PDF]

open access: yes, 2011
Label-free LC-MS/MS-based shot-gun proteomics was used to quantify the differential protein synthesis and metabolite profiling in order to assess metabolic changes during the development of citrus fruits.

Di‐myo‐inositol‐1, 1′‐phosphate: A new inositol phosphate isolated from Pyrococcus woesei

open access: yesFEBS Letters, 1992
A new inositol derivative could be isolated from the Archaeum Pyrococcus woesei and identified as di‐myo‐inositol‐1,1′‐phosphate by 1H, 31P NMR spectroscopy, mass spectrometry and thin layer chromatograpy. In P. woesel, this inositol phosphate represents the dominant counterion of K+ which ranges from 500 to 600 mM. The role of the potassium salt of di‐

Photocaged Oxytocin and Vasopressin Probes to Decipher Neuropeptide Signalling With High Spatiotemporal Resolution

open access: yesAngewandte Chemie International Edition, EarlyView.
Novel and biocompatible photoactivatable oxytocin and vasopressin probes, utilising state‐of‐the‐art photocages, remain inactive in the dark. Light exposure facilitates rapid spatiotemporal receptor activation and phospholipase C (PLC)‐mediated downstream signalling. Figure created in https://BioRender.com.

The Inositol- 1,4,5=Trisphosphate System Is Involved in Rapid Effects of Aldosterone in Human Mononuclear Leukocytes [PDF]

open access: yes, 1993
There is increasing evidence for rapid steroid action on electrolyte transport in human mononuclear leukocytes (HML). In HML, aldosterone stimulates the Na+/H+ antiporter within a few minutes. Because a variety of hormones and growth factors activate the

Myo‐Inositol Mitigates Oxidative Stress in Bovine Mammary Epithelial Cells via Activation of the SIRT5/Nrf2 Signaling Axis

open access: yesAnimal Research and One Health, EarlyView.
Myo‐inositol alleviates oxidative stress in dairy cow mammary epithelial cells via the Sirt5/Nrf2 pathway to promote mitochondrial fusion. This graphical abstract was created with BioRender.com. ABSTRACT High‐yielding dairy cows are susceptible to mammary gland oxidative stress due to prolonged intensive lactation, leading to redox imbalance.
