We previously reported a readthrough of PTC of glycosyltransferase gene B4GALNT1 with hereditary spastic paraplegia (HSP). Here we featured the readthrough of B4GALNT1 of two mutants, M4 and M2 with PTC by immunoblotting and flow cytometry after transfection of B4GALNT1 cDNAs into cells. Immunoblotting showed a faint band of full-length mutant protein of M4 but not M2 at a similar position with that of wild-type B4GALNT1. AGC sequences at immediately before and after the PTC in M4 were critical for the readthrough. Treatment of cells transfected with mutant M4 cDNA with aminoglycosides resulted in increased readthrough of PTC. Furthermore, treatment of transfectants of mutant M2 cDNA with G418 also resulted in the induction of readthrough of PTC. Both M4 and M2 cDNA transfectants showed increased\/induced bands in immunoblotting and GM2 expression in a dose-dependent manner of aminoglycosides. Results of mass spectrometry supported this effect. Here, we showed for the first time the induction and\/or enhancement of the readthrough of PTCs of B4GALNT1 by aminoglycoside treatment, suggesting that aminoglycosides are efficient for patients with HSP caused by PTC of B4GALNT1, in which gradual neurological disorders emerged with aging.<\/jats:p>","DOI":"10.1093\/jb\/mvaa041","type":"journal-article","created":{"date-parts":[[2020,4,4]],"date-time":"2020-04-04T11:11:54Z","timestamp":1585998714000},"page":"103-112","source":"Crossref","is-referenced-by-count":6,"title":["Aminoglycosides are efficient reagents to induce readthrough of premature termination codon in mutant B4GALNT1 genes found in families of hereditary spastic paraplegia"],"prefix":"10.1093","volume":"168","author":[{"given":"Farhana","family":"Yesmin","sequence":"first","affiliation":[{"name":"Department of Biomedical Sciences, Chubu University College of Life and Health Sciences, 1200 Matsumoto, Kasugai 487-8501, Japan"},{"name":"Department of Biochemistry II, Nagoya University Graduate School of Medicine, Nagoya 466-0065, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Robiul H","family":"Bhuiyan","sequence":"additional","affiliation":[{"name":"Department of Biomedical Sciences, Chubu University College of Life and Health Sciences, 1200 Matsumoto, Kasugai 487-8501, Japan"},{"name":"Department of Biochemistry and Molecular Biology, University of Chittagong, Chittagong 4331, Bangladesh"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yuhsuke","family":"Ohmi","sequence":"additional","affiliation":[{"name":"Department of Biomedical Sciences, Chubu University College of Life and Health Sciences, 1200 Matsumoto, Kasugai 487-8501, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yuki","family":"Ohkawa","sequence":"additional","affiliation":[{"name":"Department of Biomedical Sciences, Chubu University College of Life and Health Sciences, 1200 Matsumoto, Kasugai 487-8501, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Orie","family":"Tajima","sequence":"additional","affiliation":[{"name":"Department of Biomedical Sciences, Chubu University College of Life and Health Sciences, 1200 Matsumoto, Kasugai 487-8501, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tetsuya","family":"Okajima","sequence":"additional","affiliation":[{"name":"Department of Biochemistry II, Nagoya University Graduate School of Medicine, Nagoya 466-0065, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Keiko","family":"Furukawa","sequence":"additional","affiliation":[{"name":"Department of Biomedical Sciences, Chubu University College of Life and Health Sciences, 1200 Matsumoto, Kasugai 487-8501, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Koichi","family":"Furukawa","sequence":"additional","affiliation":[{"name":"Department of Biomedical Sciences, Chubu University College of Life and Health Sciences, 1200 Matsumoto, Kasugai 487-8501, Japan"},{"name":"Department of Biochemistry II, Nagoya University Graduate School of Medicine, Nagoya 466-0065, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"286","published-online":{"date-parts":[[2020,5,27]]},"reference":[{"key":"2020072821270385500_mvaa041-B1","doi-asserted-by":"crossref","first-page":"199","DOI":"10.1016\/S0167-7306(08)60022-8","volume-title":"Glycolipids","author":"Wiegandt","year":"1985"},{"key":"2020072821270385500_mvaa041-B2","doi-asserted-by":"crossref","first-page":"307","DOI":"10.1007\/978-1-4939-1154-7_14","article-title":"Glycosphingolipids in the regulation of the nervous system","volume":"9","author":"Furukawa","year":"2014","journal-title":"Adv.
