Paired locomotion appendages are hypothesized to have redeployed the developmental program of median appendages, such as the dorsal and anal fins. Compared with paired fins, and limbs, median appendages remain surprisingly understudied. Here, we report that a dominant zebrafish mutant, smoothback (smb), fails to develop a dorsal fin.

While CRISPR/Cas9-mediated genome editing allows for the successful generation of KI animals, several factors should be considered, such as low expression of the target gene, prevention of bacterial DNA integration, and in-frame editing. To circumvent these challenges, we developed a new strategy that utilizes minicircle technology and introduces a minimal promoter.

In this study, we compare a topical versus systemic (oral) administration of LY3023414, a dual PI3K/mTOR inhibitor, to prevent anal carcinogenesis in a Human Papillomavirus (HPV) mouse model of anal cancer.
Materials And Methods: transgenic mice were used to model HPV-induced anal carcinogenesis.
