Development of skeletal muscle is a complicated biological process regulated by various regulation factors and signal pathways. MicroRNAs (miRNAs) are novel gene regulators that control muscle cell development. microRNA-143 (miR-143) is highly expressed in skeletal muscle, and we found that miR-143 level is significantly increased during bovine skeletal muscle satellite cells (MSCs) differentiation process through microarray analysis and qRT-PCR detection. However, the function of miR-143 in bovine muscle development remained unclear. In our work, the functions of miR-143 in bovine MSCs myogenic differentiation were investigated. We discovered that IGFBP5 is directly regulated by miR-143 using a dual-luciferase reporter assay. Overexpression of miR-143 led to decreased level of IGFBP5 protein and restrained cell proliferation and differentiation, while downregulation of miR-143 resulted in increased levels of IGFBP5 protein and restrained cell proliferation but improved differentiation. IGFBP5, an important component of IGF signaling pathway, contributes greatly to bovine muscle cell development. A mechanism that miR-143 can regulate the proliferation and differentiation of bovine MSCs through changing expression of IGFBP5 was elucidated by our study.

D015398 Signal Transduction The intracellular transfer of information (biological activation/inhibition) through a signal pathway. In each signal transduction system, an activation/inhibition signal from a biologically active molecule (hormone, neurotransmitter) is mediated via the coupling of a receptor/enzyme to a second messenger system or to an ion channel. Signal transduction plays an important role in activating cellular functions, cell differentiation, and cell proliferation. Examples of signal transduction systems are the GAMMA-AMINOBUTYRIC ACID-postsynaptic receptor-calcium ion channel system, the receptor-mediated T-cell activation pathway, and the receptor-mediated activation of phospholipases. Those coupled to membrane depolarization or intracellular release of calcium include the receptor-mediated activation of cytotoxic functions in granulocytes and the synaptic potentiation of protein kinase activation. Some signal transduction pathways may be part of larger signal transduction pathways; for example, protein kinase activation is part of the platelet activation signal pathway.
