This disclosure relates to oligonucleotides, compositions and methods useful for reducing CTNNB1 expression, particularly in hepatocytes, for the treatment of bile duct paucity-associated conditions. Disclosed oligonucleotides for the reduction of CTNNB1 expression may be double- stranded or single- stranded, and may be modified for improved characteristics such as stronger resistance to nucleases and lower immunogenicity. Disclosed oligonucleotides for the reduction of CTNNB1 expression may also include targeting ligands to target a particular cell or organ, such as the hepatocytes of the liver.
