The polycomb repressive complex (PRC) 2 contains 3 core proteins, EZH2, SUZ12, and EED, in which the SET (suppressor of variegation-enhancer of zeste-trithorax) domain of EZH2 mediates the histone methyltransferase activity. This induces trimethylation of lysine 27 on histone H3, regulates the expression of HOX genes, and promotes proliferation and(More)
PURPOSE We determined the effects of vorinostat (suberoylanalide hydroxamic acid) and/or MK-0457 (VX-680), an Aurora kinase inhibitor on the cultured human (HL-60, OCI-AML3, and K562) and primary acute myelogenous leukemia (AML) and chronic myelogenous leukemia (CML), as well as on the murine pro-B BaF3 cells with ectopic expression of the unmutated and(More)
Four new aspartic protease genes pepAa, pepAb, pepAc and pepAd from Aspergillus niger were identified using a comparative genomic approach. All four gene products have highly conserved attributes that are characteristic of aspartic proteases; however, each one has novel sequence features. The PEPAa protease appears to represent an ortholog of a pepsin-type(More)
Ovarian cancer (OC) is the second most common and the most fatal gynecologic cancer in the United States. Over the last decade, various targeted therapeutics have been introduced but there has been no corresponding improvement in patient survival mainly because of the lack of effective early detection methods. microRNAs (miRs) are small, non-coding RNAs(More)
Retrotransposons including endogenous retroviruses and their solitary long terminal repeats (LTRs) compose >40% of the human genome. Many of them are located in intergenic regions far from genes. Whether these intergenic retrotransposons serve beneficial host functions is not known. Here we show that an LTR retrotransposon of ERV-9 human endogenous(More)
Hydroxamic acid analog pan-histone deacetylase (HDAC) inhibitors (HA-HDIs) have shown preclinical and clinical activity against human acute leukemia. Here we describe HA-HDI-resistant human acute myeloid leukemia (AML) HL-60 (HL-60/LR) cells that are resistant to LAQ824, vorinostat, LBH589, and sodium butyrate. HL-60/LR cells show increased expression of(More)
A novel protein that associates with interphase nucleus and mitotic apparatus (INMAP) was identified by screening HeLa cDNA expression library with an autoimmune serum followed by tandem mass spectrometry. Its complete cDNA sequence of 1.818 kb encodes 343 amino acids with predicted molecular mass of 38.2 kDa and numerous phosphorylation sites. The sequence(More)
The mutant JAK2V617F tyrosine kinase (TK) is present in the majority of patients with BCR-ABL-negative myeloproliferative neoplasms (MPNs). JAK2V617F activates downstream signaling through the signal transducers and activators of transcription (STAT), RAS/mitogen-activated protein kinase (MAPK), and phosphatidylinositol 3 (PI3)/AKT pathways, conferring(More)
Traumatic brain injury (TBI) is a leading cause of mortality and disability in children and young adults worldwide. Neurologic impairment is caused by both immediate brain tissue disruption and post-injury cellular and molecular events that worsen the primary neurologic insult. The β-lactam antibiotic ceftriaxone (CTX) has been reported to induce(More)
AIMS Cardiac injury is accompanied by dynamic changes in the expression of microRNAs (miRs). For example, miR-150 is down-regulated in patients with acute myocardial infarction, atrial fibrillation, dilated and ischaemic cardiomyopathy as well as in various mouse heart failure (HF) models. Circulating miR-150 has been recently proposed as a better biomarker(More)
