Protein Biomarkers for Early Detection of Pancreatic Ductal Adenocarcinoma: Progress and Challenges.

Alex Root, Peter Allen, Paul Tempst, Kenneth Yu,

Approximately 75% of patients with pancreatic ductal adenocarcinoma are diagnosed with advanced cancer, which cannot be safely resected. The most commonly used biomarker CA19-9 has inadequate sensitivity and specificity for early detection, which we define as Stage I/II cancers. Therefore, progress in next-generation biomarkers is greatly needed. Recent reports have ... Read more >>

Two metrics, a rise in serum creatinine concentration and a decrease in urine output, are considered tantamount to the injury of the kidney tubule and the epithelial cells thereof (AKI). Yet neither criterion emphasizes the etiology or the pathogenetic heterogeneity of acute decreases in kidney excretory function. In fact, whether ... Read more >>

The histone variant MacroH2A1 regulates target gene expression in part by recruiting the transcriptional coregulator PELP1.

Kristine M Hussey, Hongshan Chen, Christine Yang, Eugene Park, Nasun Hah, Hediye Erdjument-Bromage, Paul Tempst, Matthew J Gamble, W Lee Kraus,

MacroH2A1 is a histone variant harboring an ∼25-kDa carboxyl-terminal macrodomain. Due to its enrichment on the inactive X chromosome, macroH2A1 was thought to play a role in transcriptional repression. However, recent studies have shown that macroH2A1 occupies autosomal chromatin and regulates genes in a context-specific manner. The macrodomain may play ... Read more >>

Defining the role of epigenetic regulators in hematopoiesis has become critically important, because recurrent mutations or aberrant expression of these genes has been identified in both myeloid and lymphoid hematological malignancies. We found that PRMT4, a type I arginine methyltransferase whose function in normal and malignant hematopoiesis is unknown, is ... Read more >>

Proteasome-mediated processing of Def1, a critical step in the cellular response to transcription stress.

Marcus D Wilson, Michelle Harreman, Michael Taschner, Michael Taschner, James Reid, Jane Walker, Hediye Erdjument-Bromage, Paul Tempst, Jesper Q Svejstrup,

DNA damage triggers polyubiquitylation and degradation of the largest subunit of RNA polymerase II (RNAPII), a "mechanism of last resort" employed during transcription stress. In yeast, this process is dependent on Def1 through a previously unresolved mechanism. Here, we report that Def1 becomes activated through ubiquitylation- and proteasome-dependent processing. Def1 ... Read more >>

Yu-Ting Su, Chengzhuo Gao, Yu Liu, Shuang Guo, Anthony Wang, Benlian Wang, Hediye Erdjument-Bromage, Masaru Miyagi, Paul Tempst, Hung-Ying Kao,

Nucleocytoplasmic shuttling of class IIa of histone deacetylases (HDACs) is a key mechanism that controls cell fate and animal development. We have identified the filamin B (FLNB) as a novel HDAC7-interacting protein that is required for temporal and spatial regulation of vascular endothelial growth factor (VEGF)-mediated HDAC7 cytoplasmic sequestration. This ... Read more >>

Y Liu, R Raheja, N Yeh, D Ciznadija, A M Pedraza, T Ozawa, E Hukkelhoven, H Erdjument-Bromage, P Tempst, N P Gauthier, C Brennan, E C Holland, A Koff,

The TRIM family of genes is largely studied because of their roles in development, differentiation and host cell antiviral defenses; however, roles in cancer biology are emerging. Loss of heterozygosity of the TRIM3 locus in ∼20% of human glioblastomas raised the possibility that this NHL-domain containing member of the TRIM ... Read more >>

The type and the extent of tissue damage inform the prognosis of chronic kidney disease (CKD), but kidney biopsy is not a routine test. Urinary tests that correlate with specific histological findings might serve as surrogates for the kidney biopsy. We used immunoblots and ARCHITECT-NGAL assays to define the immunoreactivity ...

Regulation of mtDNA expression is critical for maintaining cellular energy homeostasis and may, in principle, occur at many different levels. The leucine-rich pentatricopeptide repeat containing (LRPPRC) protein regulates mitochondrial mRNA stability and an amino-acid substitution of this protein causes the French-Canadian type of Leigh syndrome (LSFC), a neurodegenerative disorder characterized ...

Merlin/NF2 functions upstream of the nuclear E3 ubiquitin ligase CRL4DCAF1 to suppress oncogenic gene expression.

Jonathan Cooper, Wei Li, Liru You, Gaia Schiavon, Angela Pepe-Caprio, Lu Zhou, Ryohei Ishii, Marco Giovannini, C Oliver Hanemann, Stephen B Long, Hediye Erdjument-Bromage, Pengbo Zhou, Paul Tempst, Filippo G Giancotti,

Integrin-mediated activation of PAK (p21-activated kinase) causes phosphorylation and inactivation of the FERM (4.1, ezrin, radixin, moesin) domain-containing protein Merlin, which is encoded by the NF2 (neurofibromatosis type 2) tumor suppressor gene. Conversely, cadherin engagement inactivates PAK, thus leading to accumulation of unphosphorylated Merlin. Current models imply that Merlin inhibits ... Read more >>

Superoxide dismutase 1 (SOD1) is a target for a small molecule identified in a screen for inhibitors of the growth of lung adenocarcinoma cell lines.

Romel Somwar, Hediye Erdjument-Bromage, Erik Larsson, David Shum, William W Lockwood, Guangli Yang, Chris Sander, Ouathek Ouerfelli, Paul J Tempst, Hakim Djaballah, Harold E Varmus,

We previously described four small molecules that reduced the growth of lung adenocarcinoma cell lines with either epidermal growth factor receptor (EGFR) or KRAS mutations in a high-throughout chemical screen. By combining affinity proteomics and gene expression analysis, we now propose superoxide dismutase 1 (SOD1) as the most likely target ... Read more >>

Bromodomain protein 7 interacts with PRMT5 and PRC2, and is involved in transcriptional repression of their target genes.

Sookil Tae, Vrajesh Karkhanis, Kevin Velasco, Mariana Yaneva, Hediye Erdjument-Bromage, Paul Tempst, Saïd Sif,

Histone modification regulates gene expression, and one major regulatory step in this process is the ability of proteins that recognize epigenetic marks to recruit enzymes required to specify transcriptional outcome. Here we show that BRD7 is a component of hSWI-SNF complexes that interacts with PRMT5 and PRC2. Recruitment studies revealed ... Read more >>

L3MBTL2 protein acts in concert with PcG protein-mediated monoubiquitination of H2A to establish a repressive chromatin structure.

Patrick Trojer, Alina R Cao, Zhonghua Gao, Yan Li, Jin Zhang, Xiaoqin Xu, Guohong Li, Regine Losson, Hediye Erdjument-Bromage, Paul Tempst, Peggy J Farnham, Danny Reinberg,

We have identified human MBT domain-containing protein L3MBTL2 as an integral component of a protein complex that we termed Polycomb repressive complex 1 (PRC1)-like 4 (PRC1L4), given the copresence of PcG proteins RING1, RING2, and PCGF6/MBLR. PRC1L4 also contained E2F6 and CBX3/HP1γ, known to function in transcriptional repression. PRC1L4-mediated repression ... Read more >>

SETDB1 is involved in postembryonic DNA methylation and gene silencing in Drosophila.

Dawei Gou, Monica Rubalcava, Silvia Sauer, Felipe Mora-Bermúdez, Hediye Erdjument-Bromage, Paul Tempst, Elisabeth Kremmer, Frank Sauer,

DNA methylation is fundamental for the stability and activity of genomes. Drosophila melanogaster and vertebrates establish a global DNA methylation pattern of their genome during early embryogenesis. Large-scale analyses of DNA methylation patterns have uncovered revealed that DNA methylation patterns are dynamic rather than static and change in a gene-specific ... Read more >>
