Tmem100-BAC-EGFP mice to selectively mark and purify embryonic endothelial cells of large caliber arteries in mid-gestational vascular formation.

Genesis 2021 Apr 2;59(4):e23416. Epub 2021 Mar 2.

Department of Molecular Physiology, National Cerebral and Cardiovascular Center Research Institute, Osaka, Japan.

Embryonic vascular development is achieved through the complex arrays of differentiation, proliferation, migration and mutual interaction of different cell types, and visualization as well as purification of unique cell populations are fundamental in studying its detailed mechanisms using in vivo experimental models. We previously demonstrated that Tmem100 was a novel endothelial gene encoding a small transmembrane protein, and that Tmem100 null mice showed embryonic lethality due to severe impairment of vascular formation. In the present study, we generated an EGFP reporter mouse line using a 216 kb genomic region containing mouse Tmem100 gene. Read More

Recent studies have shown that Transmembrane protein 100 (TMEM100) is a gene at locus 17q32 encoding a 134-amino acid protein with two hypothetical transmembrane domainsa, and first identified as a transcript from the mouse genome. As a downstream target gene of bone morphogenetic protein (BMP)-activin receptor-like kinase 1 (ALK1) signaling, it was activated to participate in inducing arterial endothelium differentiation, maintaining vascular integrity, promoting cell apoptosis, inhibiting metastasis and proliferation of cancer cells. However, evidence for the function of TMEM100 in inflammation is still limited. Read More

Bone Morphogenetic Protein 9 Protects against Neonatal Hyperoxia-Induced Impairment of Alveolarization and Pulmonary Inflammation.

Front Physiol 2017 13;8:486. Epub 2017 Jul 13.

Division of Neonatology, Department of Pediatrics, Leiden University Medical CenterLeiden, Netherlands.

Effective treatment of premature infants with bronchopulmonary dysplasia (BPD) is lacking. We hypothesize that bone morphogenetic protein 9 (BMP9), a ligand of the TGF-β family that binds to the activin receptor-like kinase 1 (ALK1)-BMP receptor type 2 (BMPR2) receptor complex, may be a novel therapeutic option for BPD. Therefore, we investigated the cardiopulmonary effects of BMP9 in neonatal Wistar rats with hyperoxia-induced BPD. Read More

Severe damage to the placental fetal capillary network causes mid- to late fetal lethality and reduction in placental size in Peg11/Rtl1 KO mice.

Genes Cells 2017 Feb 23;22(2):174-188. Epub 2017 Jan 23.

Department of Epigenetics, Medical Research Institute, Tokyo Medical and Dental University (TMDU), 1-5-45 Yushima, Bunkyo-ku, Tokyo, 113-8510, Japan.

Paternally expressed 11/Retrotransposon-like 1 (Peg11/Rtl1) knockout (KO) mice show mid- to late fetal lethality or late fetal growth retardation associated with frequent neonatal lethality. The lethal phenotype is largely dependent on genetic background and becomes more severe with each succeeding generation in the course of backcross experiments to C57BL/6 (B6). We previously suggested that these lethal and growth phenotypes in the fetal stages were due to severe defects in placental fetal capillaries in the labyrinth layer. Read More

Transcriptome analysis of trigeminal ganglia following masseter muscle inflammation in rats.

Mol Pain 2016 4;12. Epub 2016 Oct 4.

Department of Neural and Pain Sciences, Center to Advance Chronic Pain Research, University of Maryland Dental School, Baltimore, MD, USA.

Background: Chronic pain in masticatory muscles is a major medical problem. Although mechanisms underlying persistent pain in masticatory muscles are not fully understood, sensitization of nociceptive primary afferents following muscle inflammation or injury contributes to muscle hyperalgesia. It is well known that craniofacial muscle injury or inflammation induces regulation of multiple genes in trigeminal ganglia, which is associated with muscle hyperalgesia. Read More

Cardiovasc Res 2015 Mar 23;105(3):353-60. Epub 2014 Dec 23.

Lee Gil Ya Cancer and Diabetes Institute, Gachon University, Incheon, Republic of Korea Department of Physiology and Functional Genomics, College of Medicine, University of Florida, 1600 SW Archer Road, Room CG-20B, Gainesville, FL 32610, USA

Aims: TMEM100 was previously identified as a downstream target of activin receptor-like kinase 1 (ALK1; ACVRL1) signalling. Mutations on ALK1 cause hereditary haemorrhagic telangiectasia (HHT), a vascular disorder characterized by mucocutaneous telangiectases and visceral arteriovenous malformations (AVMs). The aims of this study are to investigate the in vivo role of TMEM100 at various developmental and adult stages and to determine the extent to which TMEM100 contributed to the development of AVMs as a key downstream effector of ALK1.

Enteric Neuroscience Program, Mayo Clinic, 200 1st Street SW, Rochester, MN 55905, USA.

Identification of markers of enteric neurons has contributed substantially to our understanding of the development, normal physiology, and pathology of the gut. Previously identified markers of the enteric nervous system can be used to label all or most neuronal structures or for examining individual cells by labeling just the nucleus or cell body. Most of these markers are excellent but have some limitations. Read More

Tmem100, an ALK1 receptor signaling-dependent gene essential for arterial endothelium differentiation and vascular morphogenesis.

Proc Natl Acad Sci U S A 2012 Jul 10;109(30):12064-9. Epub 2012 Jul 10.

First Department of Internal Medicine, Nara Medical University, Kashihara, Nara, Japan.

Members of the transforming growth factor-β superfamily play essential roles in various aspects of embryonic development and physiological organ function. Among them, bone morphogenetic protein (BMP) 9 and BMP10 regulate embryonic vascular development by activating their endothelial receptor ALK1 (activin receptor-like kinase 1, also called Acvrl1). ALK1-mediated intracellular signaling is implicated in the etiologies of human diseases, but their downstream functional proteins are largely unknown. Read More

Association of lung adenocarcinoma clinical stage with gene expression pattern in noninvolved lung tissue.

Int J Cancer 2012 Sep 28;131(5):E643-8. Epub 2012 Feb 28.

Department of Predictive and Preventive Medicine, Fondazione IRCCS, Istituto Nazionale Tumori, Milan, Italy.

Associations between clinical outcome of cancer patients and the gene expression signature in primary tumors at time of diagnosis have been reported. To test whether gene expression patterns in noninvolved lung tissue might correlate with clinical stage in lung adenocarcinoma (ADCA) patients, we compared the transcriptome of noninvolved lung samples from 60 ADCA smoker patients of clinical stage I versus 60 patients with stage>I. Quantitative PCR of 10 genes with the most significant differential expression confirmed the statistical association with clinical stage in eight genes, six of which were downregulated in high-stage patients.

Discovery of a novel neuroprotective compound, AS1219164, by high-throughput chemical screening of a newly identified apoptotic gene marker.

Eur J Pharmacol 2011 Nov 1;669(1-3):7-14. Epub 2011 Aug 1.

Pharmacology Research Laboratories, Astellas Pharma Inc., 5-2-3, Tokodai Tsukuba, Ibaraki 300-2698, Japan.

We have reported that tacrolimus (FK506), an immunosuppressive drug, and diclofenac, a non-steroidal anti-inflammatory drug, possess different modes of neuroprotective action. FK506 suppresses only thapsigargin-induced apoptosis in neuroblastoma SH-SY5Y cells while diclofenac reverses tunicamycin-induced as well as thapsigargin-induced apoptosis. The aim of this study is to discover novel compounds that exert neuroprotective properties by using the transcriptional response of a newly identified gene, which was regulated by both FK506 and diclofenac, as a surrogate screening marker in high-throughput chemical screening and characterize the compounds in comparison with FK506 and diclofenac.

Generation of mice with a conditional and reporter allele for Tmem100.

Genesis 2010 Nov 30;48(11):673-8. Epub 2010 Oct 30.

Lee Gil Ya Cancer and Diabetes Institute, Gachon University of Medicine and Science, Yunsu-Gu, Incheon, Republic of Korea.

Activin receptor-like kinase 1 (ACVRL1; ALK1) is predominantly expressed in arterial endothelial cells and plays an important role in angiogenesis. ACVRL1 mutations cause hereditary hemorrhagic telangiectasia (HHT), a genetic vascular disorder for which the underlying mechanism is poorly understood. We have found that expression of transmembrane protein 100 (Tmem100) is downregulated in the lung of Acvrl1-deficient mice; however, its function is unknown. Read More
