Abstract
This study aimed to understand the expression level of YAP1 in the skeletal muscle of Hu sheep and to reveal the regulatory mechanism of YAP1 on Hu sheep skeletal muscle satellite cells (SMSCs). Previous research by our group has found that YAP1 may affect the growth and development of Hu sheep skeletal muscle. In the present study, we found the expression of YAP1 in the skeletal muscle is higher than in other tissues of Hu sheep. Then, we detected the effect of YAP1 on proliferation and differentiation in Hu sheep SMSCs. According to the results of qPCR, CCK-8, EDU, and Western blot, compared to the group of negative control, overexpression of YAP1 promoted the proliferation and inhibited the differentiation of SMSCs according to the results of qPCR, CCK-8, EDU, Western blot, while the interference of YAP1 was on the contrary. Overall, our study suggests that YAP1 is an important functional molecule in the growth and development of skeletal muscle by regulating the proliferation and differentiation of SMSCs. These findings are of great use for understanding the roles of YAP1 in the skeletal muscle of Hu sheep.

Abstract
Objective The objective of this study was to investigate the effects of sheep slaughter age on myogenic characteristics in skeletal muscle satellite cells (SMSCs). Methods Primary SMSCs were isolated from hind leg biceps femoris muscles of Wurank lambs (slaughtered at three months, Mth-3) and adults (slaughtered at fifteen months, Mth-15). SMSCs were selected by morphological observation and fluorescence staining. Myogenic regulatory factors (MRF) and myosin heavy chain (MyHC) expressions of SMSCs were analyzed on days 1, 3, 4, and 5. Results The expressions of myogenic factor 5 (Myf5), myogenic differentiation (MyoD), Myf6, and myogenin (MyoG) in Mth-15 were significantly higher in Mth-15 than in Mth-3 on days 1, 3, and 4 (p<0.05). However, MyoG expression in Mth-15 was significantly lower than in Mth-3 on day 5 (p<0.05). The expressions of MyHC I, MyHC IIa, and MyHC IIx in Mth-15 were significantly higher than in Mth-3 on days 1 and 3 (p<0.05), and MyHC IIb were significantly lower than in Mth-3 on days 3 and 4 (p<0.05). In contrast, the expression of MyHC IIx in Mth-15 was significantly lower and MyHC IIb was significantly higher than in Mth-3 on days 5 (p<0.05). Conclusion The slaughter age altered the expression of MRFs and MyHCs in SMSCs while differentiation, which caused the variation of myogenic characteristics, and thus may affect the meat quality of Wurank sheep.

Long Noncoding RNA (lncRNA) CTTN-IT1 Elevates Skeletal Muscle Satellite Cell Proliferation and Differentiation by Acting as ceRNA for YAP1 Through Absorbing miR-29a in Hu Sheep. Front Genet 2020; 11:843. [PMID: 32849826 PMCID: PMC7427492 DOI: 10.3389/fgene.2020.00843] [Citation(s) in RCA: 12] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/13/2020] [Accepted: 07/13/2020] [Indexed: 12/26/2022] Open
Abstract
Characterizing the factors that regulate the growth and development of muscle is central to animal production. Skeletal muscle satellite cells (SMSCs) provide an important material for simulating the proliferation and differentiation of muscle cells. YAP1, which can promote muscle growth, is closely related to the proliferation of SMSCs in Hu sheep (Ovis aries). In addition, some miRNAs, such as miR-541-3p, miR-142-5p, and miR-29a, can play critical roles in muscle growth by specifically binding with their target mRNAs. Meanwhile, lncRNA can competitively bind these miRNAs and reduce the regulatory effect of miRNAs on their target genes and thus play critical roles themselves in muscle growth. However, the regulatory molecular mechanism of miRNA and lncRNA on SMSC proliferation through YAP1 remains unclear. Here, we characterized the regulatory network among YAP1 and its targeted miRNAs and lncRNAs in Hu sheep SMSCs. The potential ncRNAs that regulate YAP1 (miR-29a and CTTN-IT1) were predicted through multilevel bioinformatics analysis. Dual-luciferase assays, RT-qPCR, and western blots revealed that miR-29a can significantly reduce the mRNA and protein expression level by binding to a specific 3′-UTR of YAP1 (P < 0.05), while CTTN-IT1 can restore the expression of YAP1 through competitive binding to miR-29a. Furthermore, the mRNA and protein expression levels of MyoG, MyoD, and MyHC showed that miR-29a can inhibit the expression of genes related to the differentiation of SMSCs, and CTTN-IT1 can increase the expression of these same genes. Thus, miR-29a may inhibit the differentiation of SMSCs and CTTN-IT1 can restore this inhibition. The EdU staining assay indicated that excessive miR-29a can significantly reduce the proliferation ability of SMSCs (P < 0.05), while overexpression of CTTN-IT1 can significantly increase the proliferation of SMSCs (P < 0.01). CTTN-IT1 is a novel lncRNA that is a competing endogenous RNA (ceRNA) of miR-29a and can promote SMSC proliferation and differentiation by restoring the expression of YAP1 when it is inhibited by miR-29a in Hu sheep. Overall, our findings construct a CTTN-IT1-miR-29a-YAP1 regulatory network that will help contribute new insight into improving the muscle development of Hu sheep.
