A novel YY1-miR-1 regulatory circuit in skeletal myogenesis revealed by genome-wide prediction of YY1-miRNA network

ABSTRACT: microRNAs (miRNAs) are non-coding RNAs that regulate gene expression post-transcriptionally, and mounting evidences support the prevalence and functional significance of their interplay with transcription factors (TFs). Here we describe the identification of a regulatory circuit between muscle miRNAs (miR-1, miR-133 and miR-206) and Yin Yang 1 (YY1), an epigenetic repressor of skeletal myogenesis. Genome-wide identification of potential YY1 down-stream targets by combining computational prediction with expression profiling data reveals a large number of putative miRNA targets of YY1 during skeletal myoblasts differentiation into myotubes with muscle miRs rank on top of the list.

Murine skeletal muscle cells (C2C12 cells) were differentiated for 0, 1 or 3 days. Total RNAs were isolated from the cells and used for array profiling of miRNA expression.

Transcriptome Analysis Identifies Linc-Yy1, A Novel Functional LincRNA During Myogenesis

Project description:Little is known how lincRNAs are involved in skeletal myogenesis. Here we describe the discovery of a novel lincRNA, Linc-YY1 from the promoter of transcription factor (TF) Yin Yang 1 (YY1) gene. We demonstrate that Linc-YY1 is dynamically regulated during myogenesis in vitro and in vivo. Gain or loss of function of Linc-YY1 in C2C12 myoblast cells or satellite cells alters myogenic differentiation and in injured muscles impacts the course of regeneration. Further studies suggest LincYY1 may interact with YY1 through its middle domain to evict YY1

Expression data from mouse skeletal muscle

Project description:We generated skeletal muscle-specific knockout mice lacking the transcription factor Yin Yang 1 (YY1) and analyzed expression patterns in the skeletal muscle these mice. We used microarrays to detail the global programme of gene expression regulated by YY1.

Brown Adipose YY1 Deficiency Activates Expression of Secreted Proteins Linked to Energy Expenditure and Prevents Diet-Induced Obesity [BAT]

Project description:Analysis of brown adipose tissue from Yin Yang 1 (YY1) brown fat specific knockout mice fed a high fat diet for 3 months. YY1 deficiency in brown adipose tissue leads to strong thermogenic deficiency. The goal was to identify the genes controlled by YY1 responsible of brown fat defective function. Control mice YY1flox/flox versus YY1flox/flox; Ucp1Cre were fed a high fat diet for 3 months

Differentially expressed genes between YY1 knockdown and control cells, transfected in colorectal cancer cell line SW48

Project description:Yin Yang 1 (YY1) is a multifunctional transcription factor with critical roles in carcinogenesis and metastasis. However, its biological role and clinical impact in colorectal cancer (CRC) remain unclear. This study aimed to elucidate the oncological role of YY1 in CRC. To indentify the target genes of YY1, microarray analysis was performed on siYY1 and siControl transfected cells.

Nuclear receptor Nur77 and Yin-Yang 1 synergistically increase mitochondrial abundance and activity in macrophages [RNA-seq]

Project description:Mitochondrial biogenesis requires precise regulation of both mitochondrial-encoded and nuclear-encoded genes. Nuclear receptor Nur77 is known to regulate mitochondrial metabolism in macrophages and skeletal muscle cells. Here, we compared genome-wide Nur77 binding site and target gene expression in these two cell types, which revealed conserved roles for this nuclear receptor in the regulation of nuclear-encoded mitochondrial ribosomal proteins (MRP) and enrichment of motifs for the transcription factor Yin-Yang 1 (YY1). We show that Nur77 and YY1 interact, that YY1 increases Nur77 activity, and that their binding sites are co-enriched at MRP gene loci. Nur77 and YY1 co-expression synergistically increases mitochondrial abundance and activity in macrophages but not skeletal muscle. As such, we identify a macrophage-specific Nur77-YY1 interaction that enhances mitochondrial metabolism.
