Comprehensive Identification of miRNAs and circRNAs in the Regulation of Intramuscular and Subcutaneous Fat Deposition in Meat Ducks.

ABSTRACT: Fat deposition is an important factor that affects meat production and its quality in livestock animals, including poultry. Non-coding RNAs (ncRNAs) play an important role in duck fat deposition. This study aims to systematically identify key regulatory molecules involved in fat deposition in 8-day-old Cherry Valley ducks through transcriptomic sequencing across four sample groups: intramuscular pre-adipocytes (IMP-0), intramuscular adipocytes after 4 days of induction (IMP-4), subcutaneous pre-adipocytes (SCP-0), and subcutaneous adipocytes after 4 days of induction (SCP-4). Differential expression analysis preliminarily identified several circRNAs and miRNAs differentially expressed during adipocyte differentiation, including novel_circ_000012, novel_circ_000037, novel_circ_000089, as we
