Translational control of furina by an RNA regulon is important for left-right patterning, heart morphogenesis and cardiac valve function

Work by recent WMS PhD graduate Agnieszka Nagorska and PDRA Andreas Zaucker shows that translational control of an enzyme, FurinA, is important for normal positioning of the heart, and for cardiac valve function. FurinA cleaves the growth factor signal and morphogen, Nodal. Mutant zebrafish embryos with mis-regulated furina show premature and increased levels of FurinA, ectopic Nodal signalling, and defects in heart positioning and valve development. This is similar to human patients with mitral valve regurgitation. The findings pave the way for potential diagnostic tests for patients with heart valve dysfunctions. The work was supported by grants from the Leverhulme Trust, UKRI-BBSRC, MLSRF, and doctoral studentships from Warwick Medical School, MRC DTP, and Warwick-ARAP.
