Specific and efficient gene knockout and overexpression in mouse interscapular brown adipocytes in vivo
Summary: The classical Cre-LoxP system is time consuming. Here we detail a protocol that leverages Rosa26-LSL-Cas9;Adiponectin-Cre mice to restrict Cas9 expression in adipocytes. This enables specific deletion of target genes in brown adipocytes within 6 weeks by local injection of AAV-sgRNA into in...

| Summary: | Summary: The classical Cre-LoxP system is time consuming. Here we detail a protocol that leverages Rosa26-LSL-Cas9;Adiponectin-Cre mice to restrict Cas9 expression in adipocytes. This enables specific deletion of target genes in brown adipocytes within 6 weeks by local injection of AAV-sgRNA into interscapular brown adipose tissue. We also describe an adiponectin-promoter-driven AAV vector to express sgRNA-resistant cDNA-encoded protein for subsequent rescue. This protocol thus provides an efficient means to specifically knockout and overexpress genes in brown adipocytes in vivo.For complete details on the use and execution of this protocol, please refer to Xue et al. (2022).1 : Publisher’s note: Undertaking any experimental protocol requires adherence to local institutional guidelines for laboratory safety and ethics. |
