Outline of Final Research Achievements |
The malfunction of human single amino acid variant (SAV) of CSRP1 in LIM domain was investigated in vitro including transcriptome analysis by RNA-seq. Expression of the examined variant, which was detected on human genome database but not suggested pathogenicity, led to abnormal gene expression profile compared to the wild type control, implicating a potential for a genetic factor to related diseases or trait. The expression of several SRF and GATA target genes was affected in the transcriptome of the variant. Further biological investigation about the impact on pathophysiology including other SAVs of CSRPs would be needed to examine the significance of the variants to the disease.

Academic Significance and Societal Importance of the Research Achievements |
CSRPおよびCSRP1ヒト一アミノ酸変異による遺伝子発現制御についてin vitroでの網羅的遺伝子発現解析(RNA-seq)を行い、関連因子との協調的転写調節におけるCSRPおよび同LIMドメインの構造の重要性を示したとともに、意義が不明なヒト一アミノ酸変異においても分子機能異常を示すものがあることの実例を示した。遺伝子の一アミノ酸変異は分子機能上の多様性につながっており、疾患に影響するのはどのようなものであるのか、またどのような形で影響するのかについて分子生物学的側面を含め詳細に検討することが、疾患における遺伝的素因を理解していく上で重要であることを示唆した。
