KLHL30, a Kelch-like gene, is emerging as a significant regulator in multiple biological processes. It has been associated with pathways related to muscle development, lipid metabolism, and potentially circadian rhythm. In the context of muscle-related processes, its function is of particular importance, and genetic models could potentially further elucidate its role in these complex biological systems [1-2].

In myoblasts, KLHL30 has a crucial role. Transcriptomic and qPCR analyses show its up-regulation during myoblast differentiation. Overexpression of KLHL30 promotes myoblast differentiation and myotube formation by up-regulating myogenic transcription factors like MYOD, MYOG, and MEF2C, while its knockdown has the opposite effect. Additionally, KLHL30 decreases the number of cells in the S stage, depressing myoblast proliferation [1]. In Nelore cattle, KLHL30 is identified as a hub gene associated with intramuscular fat content, suggesting it may have effects on muscle metabolism, though the exact role in lipid metabolism is yet to be clarified [2].

In summary, KLHL30 is an essential regulator in myoblast proliferation and differentiation. Its potential role in lipid metabolism in Nelore cattle also indicates its importance in muscle-related metabolic processes. The study of KLHL30 through model-based research, such as potential KO/CKO mouse models, could further clarify its role in these biological processes and potentially in related disease conditions.
