HOOK3-RET: a novel type of RET/PTC rearrangement in papillary thyroid carcinoma..     ///    "Expression of the HOOK3-RET cDNA in NIH3T3 cells resulted in the formation of transformed foci and in tumor formation after injection into nude mice, confirming the oncogenic nature of HOOK3-RET.. "    ///    "A fusion product between exon 11 of HOOK3 and exon 12 of RET gene was identified by 5'RACE, and the presence of chimeric HOOK3-RET protein of 88 kDa was detected by western blot analysis with an anti-RET antibody.
