TRPC6-Mediated Ca Entry Essential for the Regulation of Nano-ZnO Induced Autophagy in SH-SY5Y Cells.

Recently, possible applications of zinc oxide nanoparticles (nano-ZnO) have been extensively studied owing to their ease of synthesis. However, the effect of nano-ZnO on the nervous system remains unclear. This study investigates the action of nano-ZnO on SH-SY5Y neuroblastoma cells.

AVNP2 protects against cognitive impairments induced by C6 glioma by suppressing tumour associated inflammation in rats.

Glioblastoma is a kind of malignant tumour and originates from the central nervous system. In the last century, some researchers and clinician have noticed that the psychosocial and neurocognitive functioning of patients with malignant gliomas can be impaired. Many clinical studies have demonstrated that part of patients, adults or children, diagnosed with glioblastoma will suffer from cognitive deficiency during their clinical course, especially in long-term survivors.

Pretreatment-Etidronate Alleviates CoCl Induced-SH-SY5Y Cell Apoptosis via Decreased HIF-1α and TRPC5 Channel Proteins.

Chronic hypoxic damage is one of the most common pathogenic factors that can cause neurodegenerative disorder in most cases. Etidronate (Eti) is one of the best-known earlier-generations of bisphosphonate derivatives for the treatment of bone-loss related diseases. Building on the preceding study of our laboratory, we found that Eti showed neuroprotective effects against 2-vessel occlusion induced vascular dementia (VD) in rats.

Etidronate-zinc Complex Ameliorated Cognitive and Synaptic Plasticity Impairments in 2-Vessel Occlusion Model Rats by Reducing Neuroinflammation.

As one of the bisphosphonate derivatives, etidronate has proved to be beneficial to spatial learning and memory deficits caused by two-vessel occlusion (2-VO). In this study, the novel drug etidronate-zinc complex (Eti-Zn) was used to detect its role in synaptic plasticity and learning and memory functions in a rat model of 2-VO. Chronic cerebral hypoperfusion was induced by permanent occlusion of the common carotid artery bilaterally in adult Sprague-Dawley rats.

Neuroprotective Effects of Etidronate and 2,3,3-Trisphosphonate Against Glutamate-Induced Toxicity in PC12 Cells.

Etidronate is one of the best known bisphosphonates (BP) derivatives. It is often used as a reference drug in research related to hypercalcaemia and other common bone diseases. 2,3,3-trisphosphonate (TrisPP) is brand new analogue of BP, that also contains a 'germinal bisphosphonate' unit with an additional phosphoryl group attached in proximity to the BP unit.

Cognitive deficits induced by multi-walled carbon nanotubes via the autophagic pathway.

Multi-walled carbon nanotubes (MWCNTs) have shown potential applications in many fields, especially in the field of biomedicine. Several studies have reported that MWCNTs induce apoptosis and oxidative damage in nerve cells during in vitro experiments. However, there are few studies focused on the neurotoxicity of MWCNTs used in vivo.
