Ptbx-2::gfp expression was observed in both of seam cells and gut in
ubc-9(RNAi). Surprisingly, frequent ectopic Ptbx-2::gfp expression was observed in the non-seam, syncytial hypodermis in
ubc-9(RNAi). In addition, occasional Ptbx-2::gfp expression was also observed in the ventral nerve cord. Hypodermal expression was typically found in the lateral and ventral regions of the
hyp7 syncytium flanking the seam cells.
