CellsCalcium (Ca2+) signalling is a fundamental cellular process, essential for a wide range of physiological functions. It is regulated by various mechanisms, including a diverse family of Ca2+-binding proteins (CaBPs), which are structurally and ...

FEBS Open Bio, EarlyView.Chemotherapy side effects significantly impact cancer survivors' quality of life. Using protein levels in blood samples from breast cancer patients before and after 12 weeks of taxane treatment, we detected treatment‐dependent changes in calcium signaling and aging pathways associated with cancer recurrence.

Cooperative calcium and zinc signaling underlies oxidant-induced neuronal injury [PDF]
, 2013 Intracellular zinc release triggered by oxidative injury leads to cellular K+ efflux and neuronal apoptosis. Low intracellular K+ enables protease and nuclease activation during cell death processes. Our laboratory has demonstrated that the reduction in

Acute caffeine treatment protects the developing retina from ischemia‐induced cell death
FEBS Open Bio, EarlyView.Caffeine reduces cell death in the developing retina under ischemia (OGD). This effect does not involve BDNF upregulation or antioxidant pathways (NRF2/VEGF). Neuroprotection occurs mainly through adenosine A2A receptor antagonism, decreasing glutamate release and excitotoxicity, highlighting caffeine's potential as an acute neuroprotective agent in ...

The relationship between apamin binding and channel block in KCa2 potassium channels. [PDF]
, 2013 Small conductance calcium-activated potassium channels (KCa2.1,2.2,2.3) are widely distributed throughout the body and are involved in diverse physiological processes including the regulation of neuronal firing and smooth muscle contraction.

Disparate effects of calcium channel blockers on pressure dependence of renin secretion and flow in the isolated perfused rat kidney [PDF]
, 1992 Using the model of isolated perfused rat kidneys this study was performed to investigate whether or not voltage-operated calcium channels are essentially involved in the pressure control of renin secretion from the kidneys. At a perfusion pressure of 100

Molecular Neurodegeneration, 2011 Background Familial amyloidotic polyneuropathy (FAP) is a peripheral neuropathy caused by the extracellular accumulation and deposition of insoluble transthyretin (TTR) aggregates. However the molecular mechanism that underlies TTR toxicity in peripheral

Mitochondrial calcium channels
FEBS Letters, 2010 Mitochondrial Ca2+handling plays an important role in energy production and various cellular signaling processes. Mitochondrial Ca2+uptake is regulated by the mitochondrial Ca2+uniporter (MCU), at least one non‐MCU Ca2+channel and possibly a mitochondrial ryanodine receptor. Two distinct mechanisms mediate Ca2+outward transport, the Na+‐dependent (mNCX)

FEBS Open Bio, EarlyView.Pharmacological inhibition of PERK in a DEN‐induced mouse model of liver cancer does not reduce tumor burden but alters cellular stress signaling. Despite blocking PERK activity, downstream stress responses, including CHOP expression, remain active, suggesting compensatory mechanisms within the unfolded protein response that may influence tumor ...

FEBS Open Bio, EarlyView.Early‐life exposure to a high‐fat diet altered intact Achilles tendons in rat offspring, making them thinner, stiffer, and molecularly distinct even without injury. These findings suggest that developmental high‐fat diet exposure may impair tendon quality and increase susceptibility to mechanical overload or tendon injury later in life.
