The prospect of a minimally toxic, chemotherapy-free cure for hepatoblastoma is held out by findings from a mouse model using the small-molecule drug WNTinib that inhibits the Wnt signaling pathway involved with cancer growth.

Lead author Ugnė Balaševičiūtė, a pre-doctoral researcher in Translational Research of the Hepatic Oncology Group led by Josep M. Llovet, Professor at the Institut D'Investigacions Biomediques August Pi i Sunyer (IDIBAPS) in Barcelona, Spain, reported that the CTNNB1 (catenin beta-1 protein) gene targeted by WNTinib was expressed in 90 percent of all hepatoblastomas. Hopes were high that a safer alternative to chemotherapy in humans was on the way.
