BACKGROUND: The developmental origin of health and disease concept identifies the brain, cardiovascular, liver, and kidney systems as targets of fetal adverse programming with adult consequences. As the limits of viability in premature infants have been pushed to lower gestational ages, the long-term impact of prematurity on kidneys still remains a significant burden during hospital stay and beyond. OBJECTIVES: The purpose of this study is to summarize available evidence, mechanisms, and short- and long-term renal consequences of prematurity and identify nephroprotective strategies and areas of uncertainty...

Objective: Memory impairment is an important contributor to the reduction in quality of life experienced by older adults, and genetic risk factors seem to contribute to variance in age-related cognitive decline. Brain-derived neurotrophic factor (BDNF) is an important nerve growth factor linked with development and neural plasticity. The Val66Met polymorphism in the BDNF gene has been associated with impaired episodic memory in adults, but whether this functional variant plays a role in cognitive aging remains unclear...

A variety of mouse models have been developed that express mutant huntingtin (mHTT) leading to aggregates and inclusions that model the molecular pathology observed in Huntington's disease. Here we show that although homozygous HdhQ150 knock-in mice developed motor impairments (rotarod, locomotor activity, grip strength) by 36 weeks of age, cognitive dysfunction (swimming T maze, fear conditioning, odor discrimination, social interaction) was not evident by 94 weeks. Concomitant to behavioral assessments, T2-weighted MRI volume measurements indicated a slower striatal growth with a significant difference between wild type (WT) and HdhQ150 mice being present even at 15 weeks...

Glial cell line-derived neurotrophic factor (GDNF) is widely recognized as a survival factor for dopaminergic neurons, but GDNF has also been shown to promote development, differentiation, and protection of other central nervous system neurons and was thought to play an important role in various neuropsychiatric disorders. Severe mood disorders, such as primarily major depressive disorder and bipolar affective disorder, attract particular attention. These psychopathologies are characterized by structural alterations accompanied by the dysregulation of neuroprotective and neurotrophic signaling mechanisms required for the maturation, growth, and survival of neurons and glia...

Brain‑derived neurotrophic factor (BDNF), a member of the neurotropic family, is expressed in osteoblast‑like cells of a fracture callus, however, its role in fracture healing remains to be fully elucidated. Osteoblasts isolated from Sprague Dawley rats were stimulated by BDNF in a dose‑ and time‑dependent manner. Immunoblotting and immunofluorescence was used to detect the expression and distribution of targeted proteins. The concentration of vascular endothelial growth factor (VEGF) released in medium was determined using an ELISA...

Optimal nutrition early in life is critical to ensure proper structural and functional development of infant organ systems. Although pediatric nutrition historically has emphasized research on the relation between nutrition, growth rates, and gastrointestinal maturation, efforts increasingly have focused on how nutrition influences neurodevelopment. The provision of human milk is considered the gold standard in pediatric nutrition; thus, there is interest in understanding how functional nutrients and bioactive components in milk may modulate developmental processes...

BACKGROUND: Previous studies demonstrated the cytoprotective effect of geranylgeranylacetone (GGA), a heat shock protein inducer, against ischemic insult or kainic acid (KA)-induced neuronal cell death. Phosphatidylinositol-3 kinase (PI3K)/Akt is thought to be an important factor that mediates neuroprotection. However, the signaling pathways in the brain in vivo after oral GGA administration remain unclear. METHODS: We measured and compared hippocampal neuron density to investigate the effect of GGA on KA-induced cell death in rats...

BACKGROUND: Breastfed infants follow a peculiar growth fashion characterized by a rapid weight gain in the first weeks of life, then followed by a fast decrease in growth rates, a capacity to self-regulate the sense of hungry and satiety, and a minor propensity towards overweight and obesity later on, in parallel with a better neurodevelopmental performance. METHODS: We searched studies investigating the relationship between the feeding mode in infancy and the energy balance, so the possible associations with total energy expenditure and intake regulation...

The rapid modulation of chromatin organization is thought to play a critical role in cognitive processes such as memory consolidation. This is supported in part by the dysregulation of many chromatin remodeling proteins in neurodevelopmental and psychiatric disorders. A key example is ATRX, an X-linked gene commonly mutated in individuals with syndromic and non-syndromic intellectual disability (ID). The consequences of Atrx inactivation on learning and memory have been difficult to evaluate due to the early lethality of hemizygous-null animals...

OBJECTIVES: Insulin-like Growth Factor Binding Protein 2 (IGFBP2) is a member of the family of high-affinity binding proteins (IGFBP1-6) and appears to play a governing role in Insulin-like Growth Factor (IGF) regulation in the central nervous system. This study aimed to investigate the putative involvement of IGFBP2 in mood disorder pathogenesis by measuring its expression levels in patient peripheral tissues. METHODS: IGFBP2 protein and mRNA levels were measured in the serum of 93 controls, 41 Bipolar Disorder (BD) and 43 Major Depressive Disorder (MDD) patients and in the skin fibroblasts from 15 controls, 12 BD and 23 MDD patients...

Transition from pediatric to adult health care for adolescents with epilepsy is challenging for the patient, family, and health care workers. This paper is the first of three that summarize the main findings from the 2nd Symposium on Transition in Epilepsies, held in Paris from June 14-25, 2016. In this paper we describe five basic themes that have an important effect on transition. First, there are important brain changes in adolescence that leave an imbalance between risk taking and pleasure seeking behaviors and frontal executive function compared with adults...

Insulin-like growth factor binding protein (IGFBP)-3 regulates IGF bioactivity, induces apoptosis, and inhibits cell growth independent of IGFs, but the functional role of IGFBP3 in the brain is not clear. In the present study, we revealed the effect of IGFBP3 on the brain by characterizing the phenotype of Igfbp3-null mice. Compared with wild-type mice, Igfbp3-null mice had significantly decreased IGF-1 content in the brain but no change in weights of brain and body. In Igfbp3-null mice, the number of dendritic spines was significantly reduced, and the dendritic diameter was thickening...

Diphenylarsinic acid (DPAA) was a major compound found in the arsenic poisoning incident that occurred in Kamisu, Ibaraki, Japan in 2003. People exposed to DPAA via contaminated well water suffered from several neurological disorders, including cerebellar symptoms. We previously reported that DPAA induces cellular activation in cultured rat cerebellar astrocytes, dose-dependent promotion of cell growth (low DPAA), cell death (high DPAA), and increased phosphorylation of mitogen-activated protein (MAP) kinases (p38MAPK, SAPK/JNK, and ERK1/2)...

: The circadian system may regulate adult neurogenesis via intracellular molecular clock mechanisms or by modifying the environment of neurogenic niches, with daily variation in growth factors or nutrients depending on the animal's diurnal or nocturnal life-style. In a diurnal vertebrate, zebrafish, we studied circadian distribution of immunohistochemical markers of the cell division cycle (CDC) in five of the sixteen neurogenic niches of adult brain, the dorsal telencephalon, habenula, preoptic area, hypothalamus and cerebellum...

Retinoblastoma (RB) is a tumor suppressor gene which regulates cell cycle entry to S phase via E2F transcription factors. Using knockout (KO) mice, it has been described that Rb plays a role in cell migration and differentiation in developing and adult brain as well as apoptosis. In addition, the RB family is required for the self-renewal and survival of human embryonic stem cells (ESCs). However, little is known about the role of this gene in human brain development. Here, we investigated the role of RB in cerebral organoids from human ESCs deficient for RB...

The importance of macroautophagy (hereafter referred to as autophagy) in vascular endothelial cell (VEC) biology and dysfunction is increasingly recognized, but the molecular mechanisms of autophagy in VECs in the presence of serum are still poorly understood. Previously, we identified pterostilbene as a potent autophagy inducer of VECs in the presence of serum. In this study, we used pterostilbene as a tool to induce VEC autophagy and identified the differentially expressed genes using high-throughput DAN microarray...

BACKGROUND: Epilepsy is a common and debilitating consequence of traumatic brain injury (TBI). Seizures contribute to progressive neurodegeneration and poor functional and psychosocial outcomes for TBI survivors, and epilepsy after TBI is often resistant to existing anti-epileptic drugs. The development of post-traumatic epilepsy (PTE) occurs in a complex neurobiological environment characterized by ongoing TBI-induced secondary injury processes. Neuroinflammation is an important secondary injury process, though how it contributes to epileptogenesis, and the development of chronic, spontaneous seizure activity, remains poorly understood...

OBJECTS: Meningioma is the most common intracranial neoplasm, comprising approximately 30% of all primary intracranial tumors (Claus et al., 2005) [1]. Treatment options include observation, microsurgical resection, stereotactic radiosurgery (SRS), and whole brain radiation therapy (WBRT). Gamma knife radiosurgery (GKRS) is a very effective treatment for intracranial meningiomas; previous studies showed the tumor control rate at 5-10 years of follow-up as 84.3%-100% in all cases (Feigl et al...

Neuron-targeted gene delivery is a promising strategy to treat peripheral neuropathies. Here we propose the use of polymeric nanoparticles based on thiolated trimethyl chitosan (TMCSH) to mediate targeted gene delivery to peripheral neurons upon a peripheral and minimally invasive intramuscular administration. Nanoparticles were grafted with the non-toxic carboxylic fragment of the tetanus neurotoxin (HC) to allow neuron targeting and were explored to deliver a plasmid DNA encoding for the brain-derived neurotrophic factor (BDNF) in a peripheral nerve injury model...

Silica nanoparticles (SiO2-NPs) has been extensively exploited in biomedical fields and mostly designed to enter the circulatory system, however, few studies focused on the potential adverse effects of SiO2-NPs exposure on the blood-brain barrier (BBB) that serves as a critical barrier between the central nervous system (CNS) and the peripheral circulation. This study attempts to provide an understanding of whether and how SiO2-NPs disrupts the BBB in vitro and in vivo. Through a human BBB model, we found that SiO2-NPs could induce tight junction loss and cytoskeleton arrangement, and increase inflammatory response and the release of vascular endothelial growth factor (VEGF) of brain microvessel endothelial cells (BMECs), which further activates astrocytes to amplify the generation of VEGF and increase the aquaporin-4 expression, and thus causing BBB disruption through a complex immunoregulatory loop between BMECs and astrocytes under SiO2-NPs exposure...
