“…The specific phenotypic outcomes depend on the particular Lox/Loxl gene that has been modified [ 17 , 122 , 129 , 130 , 132 , 133 , 135 , 136 , 137 , 138 , 139 , 140 , 141 ]. A few constitutive KI GEMMs have also been generated for Lox and Lolx2 genes, as well as for the Loxl2-Δe13 (L2ΔE13) splice variant, presenting milder phenotypes [ 16 , 122 , 131 , 134 ] ( Table 2 ).…”
