Genomic sequencing of iPSCs were performed. We identified a 4-bp deletion in LAMP2 at the intron 6 splice site (IVS6+1_4delGTGA) in all lines of hiPSCs same as their whole blood as previously reported. However, we could not compare the differences between LAMP2 positive and negative iPSCs, because all of the iPSC lines were stained by LAMP2 antibody IF. cDNA sequence of LAMP2 was performed. Exon6 skipping was proved in some of the hiPSC lines (miPSCs) and the other lines(ciPSCs) had normal cDNA sequence of LAMP2. We compared the difference between miPSCs and ciPSCs. The miPSCs derived cardiomyocytes had intracytoplasmic vacuoles which was thought to be autophagosome: the characteristics of danon disease. On the contrary, we could not find any abnormal vacuole in the cytoplasm of ciPSCs. We could not administer and make evaluation of the candidate therapeutic agent because of expiration of the term., 研究課題/領域番号:26860786, 研究期間(年度):2014-04-01 - 2018-03-31, 出典:研究課題「Danon病iPS細胞由来心筋・骨格筋細胞の解析と治療薬効果の評価」課題番号26860786 (KAKEN:科学研究費助成事業データベース(国立情報学研究所)) (https://kaken.nii.ac.jp/report/KAKENHI-PROJECT-26860786/26860786seika/)を加工して作成, 金沢大学附属病院循環器内科}, title = {Danon病iPS細胞由来心筋・骨格筋細胞の解析と治療薬効果の評価}, year = {2016} }
