Project description:We examined ubiquitin-linkages on Nrf1 purified from cell lysates of NGLY1-KO cells overexpressing Nrf1-FLAG with HA-FBS2. The ubiquitin linkage types were quantified using the LC-MS/MS-based absolute quantification method, ubiquitin parallel reaction monitoring (Ub-AQUA/PRM).

Project description:To explore the spectrum of Eya1-interacting partner proteins, we thus generated a stable HEK293 cell line that constitutively express the 2HA–3FLAG-Eya1 (HF-Eya1) protein, purified HF-Eya1 from the cell extracts by a tandem affinity purification protocol to reduce background (first with anti-FLAG and then with anti-HA to purify FLAG-elute) and analyzed 12bands (B1-B12) using mass spectrometry.

Project description:Expression of HIF-1a or Twist1 or Bmi1 in human hypopharyngeal cancer cell line FADU results in the drift of transcriptome profile from an epithelial cell-like signature to a mesenchymal stem cell-like signature. Stable transfection of pHA-HIF1a(dODD), pFLAG-Twist1 or pcDNA3-Bmi1 in FADU cell and analyzed the transcriptome by cDNA microarray. FADU transfected with pcDNA3.1 empty vector was used as a control of experiment.

Project description:Transcription is a major obstacle for replication fork progression and a cause of genome instability. Yra1 is an essential nuclear factor of the evolutionarily conserved family of hnRNP-like export factors that when overexpressed impairs mRNA export and cell growth. Through this ChIP-chip analysis it is shown that Yra1 binds to active chromatin and is enriched at telomeres when it is overexpressed, in agreement with a possible role of this mRNP factor in the maintenance of telomere integrity. Our data indicate that YRA1 overexpression correlates with replication impairment as inferred by the increase of Rrm3, a helicase involved in the replication fork progression, at transcribed genes and telomeres. ChIP-chip studies were perfomed with antibodies against HA-tagged Yra1 protein in wild-type cells and cells overexpressing YRA1 of the yeast S. Cerevisiae, as well as Flag-tagged Rrm3 protein in both wild-type and cells overexpressing YRA1.

Project description:Several of the thousands of human long non-coding RNAs (lncRNAs) have been functionally characterized; however, potential roles for lncRNAs in somatic tissue differentiation remain poorly understood. Here we show that a 3.7kb lncRNA, terminal differentiation-induced ncRNA (TINCR), controls human epidermal differentiation by a post-transcriptional mechanism. TINCR is required for high mRNA abundance of key differentiation genes, many of which are mutated in human skin diseases, including FLG, LOR, ALOXE3, ALOX12B, ABCA12, CASP14 and ELOVL3. TINCR-deficient epidermis lacked terminal differentiation ultrastructure, including keratohyalin granules and intact lamellar bodies. Genome-scale RNA interactome analysis revealed that TINCR interacts with a suite of differentiation mRNAs. TINCR-mRNA interaction occurs through a 25 nucleotide M-bM-^@M-^\TINCR boxM-bM-^@M-^] motif which is strongly enriched in interacting mRNAs and required for TINCR binding. A high-throughput screen to analyze TINCR binding capacity to ~9,400 human recombinant proteins revealed direct binding of TINCR RNA to the Staufen1 (STAU1) protein. STAU1-deficient tissue recapitulated the impaired differentiation seen with TINCR depletion. Loss of UPF1 and UPF2, both of which are required for STAU1-mediated RNA decay (SMD), however, lacked differentiation impacts. Instead, the TINCR/STAU1 complex seems to mediate stabilization of differentiation mRNAs, such as KRT80. These data identify TINCR as a key lncRNA required for somatic tissue differentiation, which occurs through inducible lncRNA binding to differentiation mRNAs to ensure their expression.

Genome-scale RNA interactome analysis revealed that TINCR interacts with a suite of differentiation mRNAs. TINCR-mRNA interaction occurs through a 25 nucleotide “TINCR box” motif which is strongly enriched in interacting mRNAs \and required for TINCR binding. A high-throughput screen to analyze TINCR binding capacity to ~9,400 human recombinant proteins revealed direct binding of TINCR RNA to the Staufen1 (STAU1) protein.

These data identify TINCR as a key lncRNA required for somatic tissue differentiation, which occurs through inducible lncRNA binding to differentiation mRNAs to ensure their expression. Gene expression analysis: To establish a gene expression signature for regenerated human epidermis depleted of TINCR, as well as STAU1, total RNA was isolated in biologic duplicate from organotypic cultures of cells with a non-targeting siRNA, or an siRNA to the gene of interest. This RNA was processed and then hybridized to Affymetrix HG-U133 2.0 Plus arrays.
