However, it is not clear whether the death of mice with VASN deficiency (<jats:italic>VASN<\/jats:italic><jats:sup>\u2212\/\u2212<\/jats:sup>) is related to cardiac dysfunction. The aim of this research was to ascertain whether VASN induces pathological cardiac hypertrophy by targeting myosin light chain 7 (MYL7). <jats:italic>VASN<\/jats:italic><jats:sup>\u2212\/\u2212<\/jats:sup> mice were produced by CRISPR\/Cas9 technology and inbreeding. PCR amplification, electrophoresis, real\u2010time PCR and Western blotting were used to confirm VASN deficiency. Cardiac hypertrophy was examined by blood tests, histological analysis and real\u2010time PCR, and key downstream factors were identified by RNA sequencing and real\u2010time PCR. Western blotting, immunohistochemistry and electron microscopy analysis were used to confirm the downregulation of MYL7 production and cardiac structural changes. Our results showed that sudden death of <jats:italic>VASN<\/jats:italic><jats:sup>\u2212\/\u2212<\/jats:sup> mice occurred 21\u201328\u00a0days after birth. The obvious increases in cardiovascular risk, heart weight and myocardial volume and the upregulation of hypertrophy marker gene expression indicated that cardiac hypertrophy may be the cause of death in young <jats:italic>VASN<\/jats:italic><jats:sup>\u2212\/\u2212<\/jats:sup> mice. Transcriptome analysis revealed that VASN deficiency led to MYL7 downregulation, which induced myocardial structure abnormalities and disorders. Our results revealed a pathological phenomenon in which VASN deficiency may lead to cardiac hypertrophy by downregulating MYL7 production. However, more research is necessary to elucidate the underlying mechanism.<\/jats:p>","DOI":"10.1111\/jcmm.17034","type":"journal-article","created":{"date-parts":[[2021,12,2]],"date-time":"2021-12-02T08:53:34Z","timestamp":1638435214000},"page":"88-98","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":24,"title":["Vasorin
