The photoswitchable cannabinoid azo‐HU308 enables optical control of Ca2+ dynamics in INS‐1 β‐cells via off‐target effects on TRPC channels

open access: yesFEBS Open Bio, EarlyView.
Light activation of the photoswitchable cannabinoid ligand azo‐HU308 triggers Ca2+ influx in pancreatic β‐cells through TRPC channels, independent of CB2 cannabinoid receptors. This reveals a non‐GPCR pathway for cannabinoid modulation of β‐cell Ca2+ dynamics and establishes azo‐HU308 as an optical tool to study cannabinoid signaling through TRP ...

Incorporation of Adenosine and Adenosine Triphosphate into Rat Myocardium

open access: yesJapanese Heart Journal, 1969
The isolated rat heart is perfused with adenosine-8-C14, or a mixture of ATP-8-C14 and ATP-γ-P32 of known isotope (C14/P32) ratio. The results indicate that any difference between the rate of incorporation of adenosine-C14 or ATP-C14 into myocardial nucleosides and nucleotides fraction did not show significance, and also that any difference of the C14 ...

Metformin promotes mitochondrial integrity through AMPK‐signaling in Leber's hereditary optic neuropathy

open access: yesFEBS Open Bio, EarlyView.
Metformin mediates mitochondrial quality control in Leber's hereditary optic neuropathy (LHON) fibroblasts carrying mtDNA mutations. At therapeutic levels, metformin activates AMPK signaling to restore mitochondrial dynamics by promoting fusion and restraining fission, while preserving mitochondrial mass, enhancing autophagy/mitophagy and biogenesis ...

Role of P2X7 on steroid synthesis in murine luteal cells

open access: yesBiotechnology & Biotechnological Equipment, 2016
The extracellular adenosine triphosphate (ATP) regulates different cellular functions through activating purinergic receptors as a signalling molecule or neurotransmitter. P2X7 is highly expressed in murine small luteal cells.

The role of lipid metabolism in neuronal senescence

open access: yesFEBS Open Bio, EarlyView.
Disrupted lipid metabolism, through alterations in lipid species or lipid droplet accumulation, can drive neuronal senescence. However, lipid dyshomeostasis can also occur alongside neuronal senescence, further amplifying tissue damage. Delineating how lipid‐induced senescence emerges in neurons and glial cells, and how it contributes to ageing and ...

Bone marrow-derived mesenchymal stem cells ameliorate sodium nitrite-induced hypoxic brain injury in a rat model

open access: yesNeural Regeneration Research, 2017
Sodium nitrite (NaNO2) is an inorganic salt used broadly in chemical industry. NaNO2 is highly reactive with hemoglobin causing hypoxia. Mesenchymal stem cells (MSCs) are capable of differentiating into a variety of tissue specific cells and MSC therapy ...

Detecting adenosine triphosphate in the pericellular space

open access: yesInterface Focus, 2013
Release of adenosine triphosphate (ATP) into the extracellular space occurs in response to a multiplicity of physiological and pathological stimuli in virtually all cells and tissues.

Cryo‐EM of Rationally Designed Photosystem I Nanoassembly on Graphene Validates Orientation‐Driven Enhancement of Photocatalytic Performance

open access: yesAdvanced Functional Materials, EarlyView.
The first cryo‐EM visualization and quantification of oriented Photosystem I (PSI) on single‐layer graphene is reported. Domain‐specific covalent anchoring of PSI, with the reducing side of the biophotocatalyst toward graphene, promotes three‐fold higher anodic photocurrent generation compared to a randomly physisorbed counterpart. This approach allows

<em>Bacillus anthracis</em> Edema Factor Substrate Specificity: Evidence for New Modes of Action

open access: yesToxins, 2012
Since the isolation of <em>Bacillus anthracis</em> exotoxins in the 1960s, the detrimental activity of edema factor (EF) was considered as adenylyl cyclase activity only.
