Detailed Description
Statement
Reference

Dscam11 homozygous and Dscam11/Dscam105518 transheterozygous embryonic heart cardioblasts show significant decreases in migration velocity and in filopodial and lamellopodial activities, as compared to controls. Dscam11 heterozygous embryonic heart cardioblasts also show a significant decrease in filopodial activity, but not in lamellopodial activity or migration velocity, as compared to controls.

Dscam1 hemizygous mutants exhibit mild to severe disorganisation of embryonic axon tracts. Breaks in the connectives, predominantly of the outer two fascicles are observed. In addition axon bundles aberrantly cross the midline. Some 53%-58% of Bolwig's nerve (BN) projections are defective in Dscam1 hemizygotes. In half of the "abnormal projections" the entire nerve mistargets, whereas in the remainder only a subset of axons does. Many otherwise normal projections show abnormal expansion of BN terminus at P2.

Reference

Dscam11, robo11 double heterozygotes show a more severe decrease in filopodial activity compared to either single heterozygote conditions, a more severe decrease in lamellopodial activity compared to robo11 heterozygotes, and no migration velocity defects compared to wild-type controls. Dscam11, fra3 double heterozygotes show a severe decrease in lamellopodial activity compared to wild-type controls and a more severe decrease in filopodial activity compared to either single heterozygote conditions, but do not show significant changes in migration velocity compared to wild-type controls.

The decreased filopodial and lamellopodial activities, but not the decreased migration velocity, observed in Dscam11/Dscam105518 transheterozygous embryonic heart cardioblasts are enhanced by either robo11 or fra3 heterozygosity.
