UPF1 knockdown in differentiating human myoblasts

ABSTRACT: Human myoblast cell line 54-1 is transfected with either a srambled control siRNA or siRNA against UPF1. Two days after transfection, cell were induced to differentiate by changing grow meida to differentiation media. 2 days after induction of differentiation, cells are collected for extraction of RNA.

Role of UPF1-LIN28A interaction during early differentiation of pluripotent stem cells

Project description:Two RNA binding proteins, UPF1 and LIN28A, have well-known functions in posttranscriptional regulations and stem cell differentiation. Most studies on UPF1 and LIN28A have focused on the molecular mechanism in differentiated cells and stem cell differentiation, respectively. We revealed that LIN28A directly interacts with UPF1, which happens before UPF1 forms a complex with UPF2, thereby resulting in the reduction of UPF1 phosphorylation and inhibition of nonsense-mediated mRNA decay (NMD). Our studies reveal that cell fate is determined by transcriptome regulation through UPF1-LIN28A interaction in hPSCs.

Transcriptomic analysis of day 1 (D1) differentiating WT and HDAC11-deficient mouse myoblasts

Project description:To get insight into the transcriptomic changes caused by HDAC11 loss at early myogenic differentiation, we performed RNA sequencing (RNA-Seq) in 24 h differentiated primary myoblasts from WT and HDAC11-deficient mice. Satellite cell-derived primary myoblasts were obtained after FACS isolation of skeletal muscle cells by growing them at low confluence in proliferation medium. To induce myoblast differentiation, cells were plated at high confluence and changed to differentiation media. Gene Ontology (GO) analysis of the genes upregulated in HDAC11 KO differentiating myoblasts revealed a statistically significant enrichment of cell cycle-related processes while the downregulated genes in HDAC11 KO differentiating myoblasts were enriched in “muscle system process” and “muscle contraction” GO categories.

UPF1 governs early B cell development through regulation of V(D)J recombination

Project description:The ATP-dependent RNA helicase UPF1 plays a crucial role in various mRNA degradation pathways, particularly nonsense-mediated mRNA decay (NMD). Here, we unveil a novel role of UPF1, showcasing its upregulation during the early stages of B cell development, a phenomenon that is integral to the promotion of early B cell differentiation in the bone marrow. B cell-specific Upf1 deletion in mice severely impeded early to late LPre-B cell transition when VH-DHJH recombination occurs at the Igh gene. Furthermore, UPF1 proved indispensable for VH-DHJH recombination without affecting DH-JH recombination. Intriguingly, the genetic pre-arrangement of the Igh gene managed to rescue the differentiation defect in early LPre-B cells under Upf1 deficiency. However, the differentiation ceased after the light chain recombination, leading to the failure to develop into immature B cells. Significantly, UPF1 was shown to interact with and govern the expression of genes linked to immune responses, cell cycle regulation, NMD, and unfolded protein response in B cells. Collectively, our data underscores the critical roles of UPF1 in VH-DHJH recombination at early LPre-B cell stage and enabling the gene expression transition from early Lpre- to sPre-B cell stage, thereby establishing proper B cell development.

Expression profiling FSHD vs. control myoblasts and myotubes

Project description:The gene expression pathways leading to muscle pathology in facioscapulohumeral dystrophy (FSHD) remain to be elucidated. This muscular dystrophy is caused by a contraction of an array of tandem 3.3-kb repeats (D4Z4) at 4q35.2. We compared expression of control and FSHD myoblasts and myotubes (three preparations each) on exon microarrays (Affymetrix Human Exon 1.0 ST) and validated FSHD-specific differences for representative genes by qRT-PCR on additional myoblast cell strains. The FSHD and control myoblasts used for these experiments were shown to grow and differentiate into myotubes equally efficiently as control myoblasts. There were no significant FSHD-control differences in RNA levels for MYOD1 and MYOG at the myoblast and myotube stages and for MYF5 and MYF6 at the myoblast stage. In contrast, 295 other genes were dysregulated at least 2-fold in FSHD vs. control myoblasts (p <0.01, adjusted for multiple comparisons). Remarkably, only 10% of the FSHD-associated gene dysregulation at the myoblast stage was downregulation. At the myotube stage, about ten times as many genes exhibited FSHD-associated downregulated as at the myoblast stage and twice as many genes displayed FSHD-associated upregulation. The FSHD-related changes in RNA levels appear to be due to posttranscriptional as well as transcriptional alterations. Among the prominently dysregulated pathways were signaling and oxidative stress pathways. By comparing expression profiles of control myoblasts and myotubes to each other and to 19 non-muscle cell types profiled identically, our study also revealed many new myogenesis associations for genes not previously annotated as muscle-specific. Keywords: Disease state analysis and time course for differentiation

ZIKV prevents host mRNA export from the nucleus by disrupting UPF1 function

Project description:Zika virus (ZIKV) is a mosquito-borne virus that can have dramatic neurodevelopmental consequences when infection occurs in utero. Previous studies demonstrated that ZIKV downregulates the master regulator of nonsense mediated decay, UPF1. To examine whether this process contributes to disruption of neural development, we investigated the effect of ZIKV infection on UPF1 interaction with host RNA in neural progenitor cells. Here, we show that ZIKV-mediated disruption of UPF1 function in neural progenitor cells causes retention of mRNA in the nucleus, resulting in decreased protein levels of specific transcripts involved in neural differentiation.
