Nhsl3-flox Mouse

Nhsl3, a member of the Nance-Horan Syndrome family, is involved in controlling cell migration. Although the molecular mechanisms of cell migration are not fully understood, Nhsl3 seems to play a crucial role in this biological process [1].

Gene knockout experiments of Nhsl3 have revealed interesting findings. Nhsl3-knockout cells show increased persistence in single-cell migration compared to parental cells. However, in wound healing, follower cells lacking Nhsl3 are impaired in their ability to follow leader cells. The NHSL3 locus encodes several isoforms. Specific isoforms' interactions are critical for different types of cell migration. A long isoform's interaction with MENA/VASP proteins at cell-cell junctions is essential for collective migration, while a short isoform's interaction with 14-3-3θ in lamellipodia is crucial for single-cell migration [1].

In conclusion, Nhsl3 regulates single and collective cell migration through distinct mechanisms. The gene knockout models of Nhsl3 have provided valuable insights into the role of this gene in cell migration processes, which may potentially contribute to understanding diseases related to abnormal cell migration [1].
