The B6-hALK7 (hACVR1C) mouse is a humanized model constructed using gene editing technology, where the region from aa.27 in exon 2 to partial intron 2 of mouse Acvr1c was replaced with "ACVR1C chimeric CDS-WPRE-BGH pA" cassette. The murine signal peptide (aa.1~25) of Acvr1c was preserved. This model can be used for studying the pathological mechanisms and therapeutic approaches of metabolic disorders such as obesity and type 2 diabetes, and certain cancers like retinoblastoma, and for the development of ACVR1C-targeted drugs.
