Differential expression patterns of myogenic regulatory factors in the postnatal longissimus dorsi muscle of Jeju Native Pig and Berkshire breeds along with their co-expression with Pax7

BACKGROUND: Myogenic regulatory factors (MRFs) such as MyoD, Myf6 and Myf5 play a vital role in the growth and development of muscles. Jeju Native Pig (JNP) is the top ranker in Korea amongst the indigenous livestock reared for meat purpose. Few studies covering transcript abundance of the MRFs and relat...

Molecular characterization and functional analysis of scavenger receptor class B from black tiger shrimp (Penaeus monodon)

BACKGROUND: Scavenger receptor class B (SRB) is a multifunctional protein in animals that participates in physiological processes, including recognition of a wide range of ligands. Astaxanthin is a major carotenoid found in shrimp. However, the molecular mechanism of astaxanthin and SRB protein binding h...
