Mice lacking p63 exhibit severe developmental defects such as limb truncations, abnormal skin, and absence of hair follicles, teeth, and mammary glands. Germline missense mutations of p63 have been shown to be responsible for several human developmental syndromes including SHFM, EEC and ADULT syndromes and are associated with anomalies in the development of organs of epithelial origin.

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.

We profiled the transcriptome from synaptoneurosomes (SNs) and paired total homogenates (THs) from mouse amygdala following chronic voluntary alcohol consumption. In SN, both the number of alcohol-responsive mRNAs and the magnitude of fold-change were greater than in THs, including many GABA-related mRNAs upregulated in SNs. Furthermore, SN gene co-expression analysis revealed a highly connected network, demonstrating coordinated patterns of gene expression and highlighting alcohol-responsive biological pathways, such as long-term potentiation, long-term depression, glutamate signaling, RNA processing and upregulation of alcohol-responsive genes within neuroimmune modules. Alterations in these pathways have also been observed in the amygdala of human alcoholics. SNs offer an ideal model for detecting intricate networks of coordinated synaptic gene expression and may provide a unique system for investigating therapeutic targets for the treatment of alcoholism.

    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.
