Tsang3, Alexander G. Bassuk4 and Vinit B. Mahajan1,2* Abstract Objective: Our objective was to characterize CAPN5 gene expression in the mouse central nervous system. Mouse brain and eye sections were probed with two high-afnity RNA oligonucleotide analogs designed to bind CAPN5 RNA and one scramble, control oligonucleotide. Images were captured in brightfeld. Results: CAPN5 RNA probes were validated on mouse breast cancer tumor tissue. In the eye, CAPN5 was expressed in the ganglion cell, inner nuclear and outer nuclear layers of the retina. Signal could not be detected in the ciliary body or the iris because of the high density of melanin. In the brain, CAPN5 was expressed in the granule cell layers of the hippocampus and cerebellum. There was scattered expression in pons. The visual cortex showed faint signal. Most signal in the brain was in a punctate pattern.

  • Characterization of the Goose CAPN3 Gene and Its Expression Pattern in Muscle Tissues of Sichuan White Geese at Different Growth Stages
    http://www.jstage.jst.go.jp/browse/jpsa doi:10.2141/ jpsa.0170150 Copyright Ⓒ 2018, Japan Poultry Science Association. Characterization of the Goose CAPN3 Gene and its Expression Pattern in Muscle Tissues of Sichuan White Geese at Different Growth Stages Hengyong Xu*, Yahui Zhang*, Quan Zou, Liang Li, Chunchun Han, Hehe Liu, Jiwei Hu, Tao Zhong and Yan Wang Farm Animal Genetic Resources Exploration and Innovation Key Laboratory of Sichuan Province, Sichuan Agricultural University, Chengdu 611130, China Calpain 3 (CAPN3), also known as p94, is associated with multiple production traits in domestic animals. However, the molecular characteristics of the CAPN3 gene and its expression profile in goose tissues have not been reported. In this study, CAPN3 cDNA of the Sichuan white goose was cloned, sequenced, and characterized. The CAPN3 full-length cDNA sequence consists of a 2,316-bp coding sequence (CDS) that encodes 771 amino acids with a molecular mass of 89,019 kDa. The protein was predicted to have no signal peptide, but several N-glycosylation, O- glycosylation, and phosphorylation sites. The secondary structure of CAPN3 was predicted to be 38.65% α-helical. Sequence alignment showed that CAPN3 of Sichuan white goose shared more than 90% amino acid sequence similarity with those of Japanese quail, turkey, helmeted guineafowl, duck, pigeon, and chicken. Phylogenetic tree analysis showed that goose CAPN3 has a close genetic relationship and small evolutionary distance with those of the birds. qRT-PCR analysis showed that in 15-day-old animals, the expression level of CAPN3 was significantly higher in breast muscle than in thigh tissues.

Abstract The high mortality rate of gastric cancer (GC) is in part due to the absence of initial disclosure of its biomarkers. The recognition of important genes associated in GC is therefore recommended to advance clinical prognosis, diagnosis and and treatment outcomes. The current investigation used the microarray dataset GSE113255 RNA seq data from the Gene Expression Omnibus database to diagnose differentially expressed genes (DEGs). Pathway and gene ontology enrichment analyses were performed, and a proteinprotein interaction network, modules, target genes - miRNA regulatory network and target genes - TF regulatory network were constructed and analyzed. Finally, validation of hub genes was performed. The 1008 DEGs identified consisted of 505 up regulated genes and 503 down regulated genes.

  • Calpain-10 Regulates Actin Dynamics by Proteolysis of Microtubule-Associated Protein 1B
    www.nature.com/scientificreports OPEN Calpain-10 regulates actin dynamics by proteolysis of microtubule-associated protein 1B Received: 15 September 2015 Tomohisa Hatta1, Shun-ichiro Iemura1,6, Tomokazu Ohishi2, Hiroshi Nakayama3, Accepted: 1 November 2018 Hiroyuki Seimiya 2, Takao Yasuda4, Katsumi Iizuka5, Mitsunori Fukuda4, Jun Takeda5, Published: xx xx xxxx Tohru Natsume1 & Yukio Horikawa5 Calpain-10 (CAPN10) is the calpain family protease identifed as the frst candidate susceptibility gene for type 2 diabetes mellitus (T2DM). However, the detailed molecular mechanism has not yet been elucidated. Here we report that CAPN10 processes microtubule associated protein 1 (MAP1) family proteins into heavy and light chains and regulates their binding activities to microtubules and actin flaments. Immunofuorescent analysis of Capn10−/− mouse embryonic fbroblasts shows that MAP1B, a member of the MAP1 family of proteins, is localized at actin flaments rather than at microtubules. Furthermore, fuorescence recovery after photo-bleaching analysis shows that calpain-10 regulates actin dynamics via MAP1B cleavage. Moreover, in pancreatic islets from CAPN10 knockout mice, insulin secretion was signifcantly increased both at the high and low glucose levels. These fndings indicate that defciency of calpain-10 expression may afect insulin secretion by abnormal actin reorganization, coordination and dynamics through MAP1 family processing. Calpains are a family of intracellular non-lysosomal calcium-activated neutral cysteine proteases known to cleave various substrate proteins and modulate their activities. Tere are 16 calpains, some of which are ubiquitously expressed and others displaying tissue-specifc distribution. Some calpains contain a penta-EF-hand domain (typical or classical calpains), and others do not (atypical calpains). Several calpain family members are impli- cated in the development of various diseases including Alzheimer’s disease, cataracts, ischemic stroke, traumatic brain injury, limb-girdle muscular dystrophy 2A and type 2 diabetes mellitus (T2DM)1.

  • Calpain-10 and Adiponectin Gene Polymorphisms in Korean Type 2 Diabetes Patients

Recently, several single nucleotide polymorphisms (SNPs) in calpain-10 and adiponectin gene have been report- ed to be associated with type 2 diabetes and various metabolic derangements. We investigated the associations between specific cal- pain-10 and adiponectin gene polymorphisms and Korean type 2 diabetes patients. Methods: Overall, 249 type 2 diabetes patients and 131 non-diabetic control subjects were enrolled in this study. All the subjects were genotyped for SNP-43 and -63 of calpain-10 gene and G276T and T45G frequencies of the adiponectin gene. The clinical char- acteristics and measure of glucose metabolism were compared within these genotypes. Results: Among calpain-10 polymorphisms, SNP-63 T/T were more frequent in diabetes patients, and single SNP-63 increases the susceptibility to type 2 diabetes. However, SNP-43 in calpain-10 and T45G and intron G276T in adiponectin gene were not signifi- cantly associated with diabetes, insulin resistance, nor insulin secretion. Conclusion: Variations in calpain-10, SNP-63 seems to increase the susceptibility to type 2 diabetes in Koreans while SNP-43 and adiponectin SNP-45, -276 are not associated with impaired glucose metabolism.

Noti Allergy and Clinical Immunology Branch, Health Effects Laboratory Division, National Institute for Occupational Safety and Health, Centers for Disease Control and Prevention, Morgantown, West Virginia Abstract Host-viral interaction occurring throughout the infection process between the influenza A virus (IAV) and bronchial cells determines the success of infection. Our previous studies showed that the apoptotic pathway triggered by the host cells was repressed by IAV facilitating prolonged survival of infected cells. A detailed understanding on the role of IAV in altering the cell death pathway during early-stage infection of human bronchial epithelial cells (HBEpCs) is still unclear. We investigated the gene expression profiles of IAV-infected vs. mock-infected cells at the early stage of infection with a PCR array for death receptor (DR) pathway. At early stages infection (2 h) with IAV significantly upregulated DR pathway genes in HBEpCs, whereas 6 h exposure to IAV resulted in down-regulation of the same genes. IAV replication in HBEpCs decreased the levels of DR pathway genes including TNF-receptor superfamily 1, Fas-associated death domain, caspase-8, and caspase-3 by 6 h, resulting in increased survival of cells.

Post mortem meat tenderization is primarily the result of calpain mediated degradation of key proteins within muscles fibers. e calpain system originally comprised three molecules: two Ca2+-dependent proteases and a specific inhibitor. Numerous studies have shown that the calpain system plays a central role in postmortem proteolysis and meat tenderization.
