Abdominal surgery under ketamine anesthesia during second trimester impairs hippocampal learning and memory of offspring by regulating dendrite spine remodeling in rats. Neurotoxicology 2024; 101:82-92. [PMID: 38346645 DOI: 10.1016/j.neuro.2024.02.003] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/01/2023] [Revised: 02/01/2024] [Accepted: 02/07/2024] [Indexed: 02/23/2024]
Abstract
Recent evidence showed that general anesthesia produces long-term neurotoxicity and cognitive dysfunction. However, it remains unclear whether maternal non-obstetric surgery under ketamine anesthesia during second trimester causes cognitive impairment in offspring. The present study assigned pregnant rats into three groups: 1) normal control group receiving no anesthesia and no surgery, 2) ketamine group receiving ketamine anesthesia for 2 h on the 14th day of gestation but no surgery, and 3) surgery group receiving abdominal surgery under ketamine anesthesia on the 14th day of gestation. On postnatal day 1, the offspring rats in Ketamine group and surgery group were assigned to receive intra-peritoneal injection of Senegenin (15 mg/kg), once per day for consecutive 14 days. The offspring's spatial perception, anxiety-like behavior, and learning and memory were evaluated. Then the offspring's hippocampal tissues were collected. The offspring of the surgery group were impaired in the spatial perception in the cliff avoidance test and the spatial learning and memory in the Morris water maze test. Accordingly, the activity of histone deacetylases increased, the protein levels of NEDD9, BDNF, p-TrkB, Syn and PSD-95 decreased, and the density of dendritic spines reduced in the hippocampus of the offspring of the surgery group, and such effects were not seen in the offspring of the ketamine group, neither in the offspring of control group. Senegenin alleviated the learning and memory impairment, and increased the protein levels of NEDD9, BDNF, p-TrkB, Syn and PSD-95 and the density of dendritic spines in the offspring of the surgery group. ketamine anesthesia plus surgery during second trimester impairs hippocampus-dependent learning and memory, and the deficits could be rescued by treatment with Senegenin.

Abstract
People with schizophrenia show hyperactivity in the ventral hippocampus (vHipp) and we have previously demonstrated distinct behavioral roles for vHipp cell populations. Here, we test the hypothesis that parvalbumin (PV) and somatostatin (SST) interneurons differentially innervate and regulate hippocampal pyramidal neurons based on their projection target. First, we use eGRASP to show that PV-positive interneurons form a similar number of synaptic connections with pyramidal cells regardless of their projection target while SST-positive interneurons preferentially target nucleus accumbens (NAc) projections. To determine if these anatomical differences result in functional changes, we used in vivo opto-electrophysiology to show that SST cells also preferentially regulate the activity of NAc-projecting cells. These results suggest vHipp interneurons differentially regulate that vHipp neurons that project to the medial prefrontal cortex (mPFC) and NAc. Characterization of these cell populations may provide potential molecular targets for the treatment schizophrenia and other psychiatric disorders associated with vHipp dysfunction.

Abstract
NEDD9 (neural precursor cell expressed, developmentally down-regulated 9) is a member of the CAS (Crk-associated substrate) family of scaffolding proteins that regulate cell adhesion and migration. A Nedd9 knock-out/lacZ knock-in mouse (Nedd9(-/)(-)) was developed in order to study Nedd9 expression and function in the nervous system. Herein we show that NEDD9 is expressed in the adult brain and is prominently expressed in the hippocampus. Behavioral testing uncovered functional deficits in Nedd9(-)(/)(-) mice. In the Morris water maze test, Nedd9(-)(/)(-) mice showed deficits in both the ability to learn the task as well as in their ability to recall the platform location. There was no change in the gross morphology of the hippocampus, and stereological analysis of BrdU-labeled newly formed hippocampal cells suggested that this defect is not secondary to altered neurogenesis. However, analysis of the hippocampus revealed extensive loss of dendritic spine density in both the dentate gyrus (DG) and CA1 regions. Spine loss occurred equally across all branch orders and regions of the dendrite. Analysis of spine density in Nedd9(-)(/)(-) mice at 1.5, 6 and 10 months revealed an age-dependent spine loss. This work shows that NEDD9 is required for the maintenance of dendritic spines in the hippocampus, and suggests it could play a role in learning and memory.

Abstract
Cancer progression requires a significant reprogramming of cellular signaling to support the essential tumor-specific processes that include hyperproliferation, invasion (for solid tumors) and survival of metastatic colonies. NEDD9 (also known as CasL and HEF1) encodes a multi-domain scaffolding protein that assembles signaling complexes regulating multiple cellular processes relevant to cancer. These include responsiveness to signals emanating from the T and B cell receptors, integrins, chemokine receptors, and receptor tyrosine kinases, as well as cytoplasmic oncogenes such as BCR-ABL and FAK- and SRC-family kinases. Downstream, NEDD9 regulation of partners including CRKL, WAVE, PI3K/AKT, ERK, E-cadherin, Aurora-A (AURKA), HDAC6, and others allow NEDD9 to influence functions as pleiotropic as migration, invasion, survival, ciliary resorption, and mitosis. In this review, we summarize a growing body of preclinical and clinical data that indicate that while NEDD9 is itself non-oncogenic, changes in expression of NEDD9 (most commonly elevation of expression) are common features of tumors, and directly impact tumor aggressiveness, metastasis, and response to at least some targeted agents inhibiting NEDD9-interacting proteins. These data strongly support the relevance of further development of NEDD9 as a biomarker for therapeutic resistance. Finally, we briefly discuss emerging evidence supporting involvement of NEDD9 in additional pathological conditions, including stroke and polycystic kidney disease.

Adaptors for disorders of the brain? The cancer signaling proteins NEDD9, CASS4, and PTK2B in Alzheimer's disease. Oncoscience 2014; 1:486-503.

Abstract
No treatment strategies effectively limit the progression of Alzheimer's disease (AD), a common and debilitating neurodegenerative disorder. The absence of viable treatment options reflects the fact that the pathophysiology and genotypic causes of the disease are not well understood. The advent of genome-wide association studies (GWAS) has made it possible to broadly investigate genotypic alterations driving phenotypic occurrences. Recent studies have associated single nucleotide polymorphisms (SNPs) in two paralogous scaffolding proteins, NEDD9 and CASS4, and the kinase PTK2B, with susceptibility to late-onset AD (LOAD). Intriguingly, NEDD9, CASS4, and PTK2B have been much studied as interacting partners regulating oncogenesis and metastasis, and all three are known to be active in the brain during development and in cancer. However, to date, the majority of studies of these proteins have emphasized their roles in the directly cancer relevant processes of migration and survival signaling. We here discuss evidence for roles of NEDD9, CASS4 and PTK2B in additional processes, including hypoxia, vascular changes, inflammation, microtubule stabilization and calcium signaling, as potentially relevant to the pathogenesis of LOAD. Reciprocally, these functions can better inform our understanding of the action of NEDD9, CASS4 and PTK2B in cancer.

Abstract
The NEDD9 rs760678 polymorphism has been extensively investigated for association to Alzheimer's disease (AD), however, results of different studies have been inconsistent. The objective of this study is to assess the relationship of NEDD9 rs760678 polymorphism and AD risk by using meta-analysis. Systematic searches of electronic databases Pubmed and Embase, as well as hand searching of the references of identified articles were performed. Statistical analyses were performed using software Revman 4.2 and STATA 11.0. A total of 4436 cases and 4420 controls in 11 case-control studies were included. The results indicated that the homozygote GG had a 13% decreased risk of AD, when compared with the C allele carriers (CC+CG) (OR=0.87, 95%CI=0.77-0.99, P=0.04 for GG vs. CG+CC). In the subgroup analysis by ethnicity, significant decreased risk was associated with homozygote GG or G allele carriers in Caucasians (OR=0.84, 95%CI=0.74-0.96, P=0.008 for GG vs. CG+CC; OR=0.79, 95%CI=0.69-0.91, P=0.001 for GG vs. CC; OR=0.90, 95%CI=0.84-0.96, P=0.002 for G vs. C), but not in Asians. This meta-analysis suggests that the GG genotype of NEDD9 rs760678 polymorphism would be a protective factor for AD in Caucasians but not in Asians. To further evaluate the effect of gene-gene and gene-environmental interactions between NEDD9 rs760678 polymorphism and the risk of AD, more studies with larger number of subjects are required.

Abstract
Neural precursor cell-expressed, developmentally downregulated 9 (NEDD9) has been suspected to be associated with Alzheimer's disease (AD) through participating in the formation of neurite-like membrane extensions and neurite outgrowth to affect the number of neuronal cells/synapses in the brain under stressful conditions. A recent large-scale, multi-tiered association study has identified significant association of a common single nucleotide polymorphism (SNP) rs760678 in the NEDD9 gene with predisposition to late-onset Alzheimer's disease (LOAD) in Caucasians. In order to evaluate the involvement of the NEDD9 polymorphism in the risk of sporadic LOAD, we performed an independent case-control association study to analyze the genotype and allele distributions of the NEDD9 rs760678 polymorphism in a Han Chinese population (383 LOAD cases and 369 healthy controls). There were significant differences in genotype and allele frequencies between LOAD cases and controls (genotype P=0.003, allele P=0.002). After stratification by APOE ε4-carrying status, the C allele of rs760678 was only significantly associated with LOAD in non-APOE ε4 allele carriers (OR=1.43, 95%, CI=1.06-1.94, P=0.024). In addition, a logistic regression analysis also conferred positive association between the SNP rs760678 and LOAD (dominant model: OR=2.10, 95% CI=1.23-3.58, P=0.007; additive model: OR=1.37, 95% CI=1.09-1.74, P=0.008) after adjustment for age, gender, and the APOE ε4 carrier status. The study demonstrated a significant association between the tested SNP and LOAD, indicating that NEDD9 polymorphism has a possible role in changing the genetic susceptibility to LOAD in a Han Chinese population.
