Myogenic regulatory factors are key players in determining muscle mass and meat quality in Jeju native and Berkshire pigs.

ABSTRACT:

Background

Meat from Jeju native pigs (JNPs) is highly popular among Korean consumers; however, the production efficiency is limited due to the low adult body weight. In contrast, the Berkshire breed, which has a genetic background closely related to Asian native pigs, gains weight more efficiently.

Objectives

This study focused on the differential expression of genes related to muscle growth in postnatal myogenesis between Berkshire and JNPs, specifically the myogenic regulatory factor (MRF) genes (MyoD, Pax7, Myf5, Myf6 and MyBPH). The MRF family is primarily involved in the proliferation and development of muscle.

Methods

Qualitative reverse transcription-polymerase chain reaction and western blot analyses revealed that expression of MyoD and Pax7 was significantly
