The aim of this study is to investigate the effects of long-chain noncoding RNA plasmacytoma variant translocation 1 (PVT1) on the activation of astrocytes and the expression of brain-derived neurotrophic factor (BDNF) in hippocampus tissues of epileptic rats. The epilepsy rat model was induced by intraperitoneal injection of lithium chloride-pilocarpine. Successfully modeled rats were grouped, and their spatial learning and memory, neuronal loss, number of TdT-mediated dUTP nick labeling (TUNEL)-positive cells, and the expression of cleaved-caspase-3, pro-caspase-3, Bax, Bcl-2, GFAP, BDNF, tumor necrosis factor-α (TNF-α), interleukin-1β (IL-1β), IL-6, axin, and cyclin D1 in hippocampus tissues were evaluated. Increased expression of PVT1 was found in hippocampus tissues of epileptic rats. Silencing of PVT1 improved spatial learning and memory, decreased neuronal loss, decreased the number of TUNEL-positive cell, decreased the expression of cleaved-caspase-3 and Bax while increased pro-caspase-3 and Bcl-2 expression, decreased the expression of GFAP, increased the expression of BDNF, decreased the expression of TNF-α, IL-1β, and IL-6, and decreased the expression of axin and cyclin D1 in hippocampus tissues in epileptic rats.

Astrocytes are glial cells that support the blood-brain barrier, facilitate neurotransmission, provide nutrients to neurons, and help repair damaged nervous tissues. Here is the latest research.

brain injury after impact to the head is due to both immediate mechanical effects and delayed responses of neural tissues.
