The growth delay and chondrocyte malformation induced by kmt2d deficiency can be partially alleviated by the inhibition of Akt. a and b) The levels of the p-Akt (ser473) and p-β-catenin (ser552) proteins. The band density was quantified and expressed as the relative gray value (compared with the control) by arbitrarily setting the control value as 1. Data were pooled from 3 independent experiments, and the results were represented as mean ± SD. c) The reduced body length in kmt2d knockdowns was partially alleviated by ZSTK474. n = 10 for each group. d and e) The asymmetrical morphology ceratohyal and Meckel’s cartilage in kmt2d knockdowns was partially corrected. n = 10 for each group. Scale bar: d) 100 μm. *P < 0.05, **P < 0.001, ***P < 0.0001. Cb, ceratobranchial; Ch, ceratohyal; M, Meckel’s cartilage; Pq, palatoquadrate.
