MiR-140-5p targets Prox1 to regulate the proliferation and differentiation of neural stem cells through the ERK/MAPK signaling pathway.

Ann Transl Med 2021 Apr;9(8):671

Department of Neurology and Institute of Neurology, Ruijin Hospital, School of Medicine, Shanghai Jiao Tong University, Shanghai, China.

Background: The expression of miR-140-5p increased in the brain tissue of a bilateral common carotid artery ligation model, while the overexpression of miR-140-5p significantly decreased the number of neurons. The luciferase report experiment in the previous study proved that miR-140-5p negatively regulated one of the potential targets of Prospero-related homeobox 1 (Prox1). Therefore, we want to investigate the effect of miR-140-5p on the proliferation and differentiation of neural stem cells (NSCs) and the underlying mechanism. Read More

Unilateral vagotomy alters astrocyte and microglial morphology in the nucleus tractus solitarii of the rat.

Am J Physiol Regul Integr Comp Physiol 2021 May 12. Epub 2021 May 12.

Area Pathobiology, University of Missouri, Columbia, MO, United Statesgrid.134936.a.

The nucleus tractus solitarii (nTS) is the initial site of integration of sensory information from the cardiorespiratory system and contributes to reflex responses to hypoxia. Afferent fibers of the bilateral vagus nerves carry input from the heart, lungs, and other organs to the nTS where it is processed and modulated. Vagal afferents and nTS neurons are integrally associated with astrocytes and microglia which contribute to neuronal activity and influence cardiorespiratory control. Read More

The diagnostic competence of Glial Fibrillary Acidic Protein in mild traumatic brain injury and its prognostic value in patient recovery.

Turk Neurosurg 2020 Jul 6. Epub 2020 Jul 6.

Ahvaz Jundishapur University of Medical Sciences, Ahvaz, Iran.

Aim: Aim: In clinical assessments and literature conducted on TBI, the mild TBI is less studied, because the initial symptoms are non-specific and subjective, and have overlap with psychological disorders. Glial Fibrillary Acidic Protein (GFAP) is a protein expressed by most of the abundant cells of the CNS. Therefore, this paper attempted to show whether the GFAP levels are significantly higher in the serum of patients with mild traumatic brain injury Material and Methods: The level of serum GFP was measured in 176 patients suffering from brain trauma.

Fenofibrate (a PPAR-α Agonist) Administered During Ethanol Withdrawal Reverts Ethanol-Induced Astrogliosis and Restores the Levels of Glutamate Transporter in Ethanol-Administered Adolescent Rats.

Front Pharmacol 2021 20;12:653175. Epub 2021 Apr 20.

Institute of Biomedical Sciences, Faculty of Health Sciences, Universidad Autónoma de Chile, Santiago, Chile.

High-ethanol intake induces a neuroinflammatory response, which has been proposed as responsible for the maintenance of chronic ethanol consumption. Neuroinflammation decreases glutamate transporter (GLT-1) expression, increasing levels of glutamate that trigger dopamine release at the corticolimbic reward areas, driving long-term drinking behavior. The activation of peroxisome proliferator-activated receptor alpha (PPARα) by fibrates inhibits neuroinflammation, in models other than ethanol consumption. Read More
