Although no bleeding or thrombotic tendency was detected, routine coagulation screening tests revealed slightly lower plasma fibrinogen levels, as determined by functional and antigenic measurements (functional/antigenic ratio=0.857), suggesting hypodysfibrinogenemia.  Materials and methods: DNA sequence and functional analyses were performed on purified plasma fibrinogen, and recombinant variant fibrinogen was synthesized in Chinese hamster ovary cells based on the results obtained.  Results: DNA sequencing revealed a heterozygous A alpha C472S substitution (mature protein residue number) in the alpha C-domain. A alpha C472S fibrinogen indicated the presence of additional disulfide-bonded molecules, and markedly impaired lateral aggregation of protofibrils in spite of slightly lower functional plasma fibrinogen levels. Scanning electron microscopic observations showed a thin fiber fibrin clot, and t-PA and plasminogen-mediated clot lysis was similar to that of a normal control. Recombinant variant fibrinogen-producing cells demonstrated that destruction of the A alpha 442C-472C disulfide bond did not prevent the synthesis or secretion of fibrinogen, whereas the variant A alpha chain of the secreted protein was degraded faster than that of the normal control.  Conclusion: Our results suggest that A alpha C472S fibrinogen may cause dysfibrinogenemia, but not hypofibrinogenemia. The destruction and steric hindrance of the alpha C-domain of variant fibrinogen led to the impaired lateral aggregation of protofibrils and t-PA and plasminogen-mediated fibrinolysis, as well as several previously reported variants located in the alpha C-domain, and demonstrated the presence of disulfide-bonded molecules.","subitem_description_type":"Abstract"}]},"item_6_description_30":{"attribute_name":"資源タイプ（コンテンツの種類）","attribute_value_mlt":[{"subitem_description":"Article","subitem_description_type":"Other"}]},"item_6_description_5":{"attribute_name":"引用","attribute_value_mlt":[{"subitem_description":"THROMBOSIS RESEARCH. 135(4):710-717 (2015)","subitem_description_type":"Other"}]},"item_6_link_3":{"attribute_name":"信州大学研究者総覧へのリンク","attribute_value_mlt":[{"subitem_link_text":"Okumura, Nobuo","subitem_link_url":"http://soar-rd.shinshu-u.ac.jp/profile/ja.OVnmgCkh.html"}]},"item_6_link_67":{"attribute_name":"WoS","attribute_value_mlt":[{"subitem_link_url":"http://gateway.isiknowledge.com/gateway/Gateway.cgi?&GWVersion=2&SrcAuth=ShinshuUniv&SrcApp=ShinshuUniv&DestLinkType=FullRecord&DestApp=WOS&KeyUT=000351086000024"}]},"item_6_publisher_4":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"PERGAMON-ELSEVIER SCIENCE LTD"}]},"item_6_relation_47":{"attribute_name":"PubMed","attribute_value_mlt":[{"subitem_relation_name":[{"subitem_relation_name_text":"25613923"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://pubmed.ncbi.nlm.nih.gov/25613923","subitem_relation_type_select":"PMID"}}]},"item_6_relation_48":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_name":[{"subitem_relation_name_text":"10.1016/j.thromres.2015.01.013"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://doi.org/10.1016/j.thromres.2015.01.013","subitem_relation_type_select":"DOI"}}]},"item_6_rights_62":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"© 2015, Elsevier.
