Apoptosis-inducing factor and calpain upregulation in glutamate-induced injury of rat spiral ganglion neurons
Spiral ganglion neuron (SGN) damage and apoptosis can lead to noise-induced hearing loss, age-associated hearing loss and, in certain cases, auditory neuropathy. The apoptosis-inducing factor (AIF)-associated pathway may be important in this process. The present study aimed to investigate the expression levels of AIF and calpain in damaged SGNs. Glutamate (Glu) perfusion and cell culture in dif...
متن کاملCritical role of calpain I in mitochondrial release of apoptosis-inducing factor in ischemic neuronal injury.
Loss of mitochondrial membrane integrity and release of apoptogenic factors are a key step in the signaling cascade leading to neuronal cell death in various neurological disorders, including ischemic injury. Emerging evidence has suggested that the intramitochondrial protein apoptosis-inducing factor (AIF) translocates to the nucleus and promotes caspase-independent cell death induced by gluta...
متن کاملSimilar to Spironolactone, Oxymatrine Is Protective in Aldosterone-Induced Cardiomyocyte Injury via Inhibition of Calpain and Apoptosis-Inducing Factor Signaling
Accumulating evidence indicates that oxymatrine (OMT) possesses variously pharmacological properties, especially on the cardiovascular system. We previously demonstrated that activated calpain/apoptosis-inducing factor (AIF)-mediated pathway was the key molecular mechanism in aldosterone (ALD) induces cardiomyocytes apoptosis. In the present study, we extended the experimentation by investigati...
متن کاملApoptosis-inducing factor
Although the seminal paper by Kerr, Wyllie and Currie (Kerr et al., 1972), who coined the word ‘apoptosis’, stated that only nuclei but not cytoplasmic organelles would undergo major modifications in the dying cell, recent evidence suggests that no cellular compartment is spared (Ferri and Kroemer, 2001). Mitochondria are particularly affected early during the apoptotic process, and they are no...
متن کاملCalpain activation contributes to hyperglycaemia-induced apoptosis in cardiomyocytes.
AIMS Cardiomyocyte apoptosis contributes to cardiac complications of diabetes. The aim of this study was to investigate the role of calpain in cardiomyocyte apoptosis induced by hyperglycaemia. METHODS AND RESULTS In cultured adult rat ventricular cardiomyocytes, high glucose (33 mM) increased calpain activity and induced apoptosis, concomitant with the impairment of Na+/K+ ATPase activity. T...
