Membrane-proximal and truncated mutations of colony-stimulating factor 3 receptor (CSF3R) are frequently found in chronic neutrophilic leukemia (CNL) and atypical chronic myeloid leukemia (aCML). However, rearrangement involving CSF3R in hematological neoplasms has not been reported. Here, we report a case of a 21-year-old female diagnosed as aCML with t(1;9)(p34;q34) who presented a CSF3R rearrangement. First, RNA sequencing identified a novel fusion transcript involving exon 17 of CSF3R and exon 50 of non-erythrocytic-1-spectrin-alpha (SPTAN1)...

PURPOSE OF REVIEW: We reviewed recent diagnostic and therapeutic progress in chronic neutrophilic leukemia (CNL) and atypical chronic myeloid leukemia (aCML). We summarized recent genetic data that may guide future efforts towards implementing risk-adapted therapy based on mutational profile and improving disease control and survival of affected patients. RECENT FINDINGS: Recent genetic data in CNL and aCML prompted modifications to the World Health Organization (WHO) diagnostic criteria, which have improved our understanding of how CNL and aCML are different diseases despite sharing common findings of peripheral granulocytosis and marrow myeloid hyperplasia...

Disease resistance genes (R genes), as part of the plant defense system, have coevolved with corresponding pathogen molecules. The main objectives of this project were to identify non-Toll interleukin receptor, nucleotide-binding site, leucine-rich repeat (nTNL) genes and elucidate their evolutionary divergence across six plant genomes. Using reference sequences from Arabidopsis, we investigated nTNL orthologs in the genomes of common bean, Medicago, soybean, poplar, and rice. We used Hidden Markov Models for sequence identification, performed model-based phylogenetic analyses, visualized chromosomal positioning, inferred gene clustering, and assessed gene expression profiles...

Ginseng, Panax ginseng C.A. Meyer, is one of the most important medicinal plants for human health and medicine. It has been documented that over 80% of genes conferring resistance to bacteria, viruses, fungi and nematodes are contributed by the nucleotide binding site (NBS)-encoding gene family. Therefore, identification and characterization of NBS genes expressed in ginseng are paramount to its genetic improvement and breeding. However, little is known about the NBS-encoding genes in ginseng. Here we report genome-wide identification and systems analysis of the NBS genes actively expressed in ginseng (PgNBS genes)...

In this study, we have established an effective and novel nanocarrier system for the effective treatment of glioma. We have established the glioma tissue penetrating nanocarrier system by conjugating Pep-1 as a targeting ligand on the liposome surface to enhance the anticancer efficacy of cilengitide (CGL). The particles were nanosized and exhibited a controlled release of drug in both the pH conditions. The cellular uptake assay showed that conjugation of Pep-1 on the liposome surface remarkably increased the cellular uptake...

The light subunit of mushroom Agaricus bisporus tyrosinase (LSMT) is a protein of unknown function that was discovered serendipitously during the elucidation of the crystal structure of the enzyme. The protein is non-immunogenic and can penetrate the intestinal epithelial cell barrier, and thus, similar to its structural homologue HA-33 from Clostridium botulinum, may be potentially absorbable by the intestine. LSMT also shares high structural homology with the ricin-B-like lectin from the mushroom Clitocybe nebularis (CNL), which has been shown to display biological activity against leukemic cancer cells and dendritic cells...

Plant resistance conferred by nucleotide binding site (NBS)-encoding resistance genes plays a key role in the defense against various pathogens throughout the entire plant life cycle. However, comparative analyses for the systematic evaluation and determination of the evolutionary modes of NBS-encoding genes among Solanaceae species are rare. In this study, 447, 255, and 306 NBS-encoding genes were identified from the genomes of potato, tomato, and pepper, respectively. These genes usually clustered as tandem arrays on chromosomes; few existed as singletons...

The clinical nurse leader (CNL) role has been cited as an effective strategy for improving care at the microsystem level. The purpose of this article is to describe the use of the CNL role in an academic medical center for evaluating pressure ulcer reporting. The Plan-Do-Study-Act cycle was used as the methodological framework for the study. The CNL assessment of pressure ulcers resulted in a 21% to 50% decrease in the number of hospital-acquired pressure ulcers reported in a 3-month time period. The CNL role has potential for improving the validity and reliability of pressure ulcer reporting...

Pathogenic meningococci have acquired a 24 kb capsule synthesis island (cps) by horizontal gene transfer which consists of a synthetic locus and associated capsule transport genes flanked by repetitive Regions D and D'. Regions D and D' contain an intact gene encoding a UDP-galactose epimerase (galE1) and a truncated remnant (galE2), respectively. In this study, GalE protein alleles were shown to be either mono-functional, synthesising UDP-galactose (UDP-Gal), or bi-functional, synthesising UDP-Gal and UDP-galactosamine (UDP-GalNAc)...

Chronic neutrophilic leukemia (CNL) and chronic myelomonocytic leukemia (CMML) are rare hematologic neoplasms. We performed CSF3R, SRSF2 and SETBP1 mutational analyses in 10 CNL and 56 CMML patients. In this sample cohort, 80% of CNL patients harbored CSF3R mutations, of which the CSF3R T618I mutation was dominant. Mutations in CSF3R and SETBP1 were found in 7.1% and 5.3% CMML patients respectively, while 25% of CMML patients carried SRSF2 mutations. Strikingly, we identified that all of the CSF3R mutations detected in CMML patients were represented by a P733T mutation...

The movement to advance the clinical nurse leader (CNL) as an innovative new role for meeting higher health care quality standards continues with CNL programs offered on-line at colleges and universities nationwide. Collaborative learning activities offer the opportunity for CNL students to gain experience in working together in small groups to negotiate and solve care process problems. The challenge for nurse educators is to provide collaborative learning activities in an asynchronous learning environment that can be considered isolating by default...

The formation of charge neutrality level (CNL) in highly conducting Cadmium oxide (CdO) thin films is demonstarted by the observed variation in the band gap upon annealing and doping. It may be explained by the observation that Tin (Sn) doping breaks the perfect periodicity of CdO cubic crystal structure and creates virtual gap states (ViGS). The level of local CNL resides at the branch point of ViGS, making the energy at which native defect's character changes from predominantly donor-like below CNL to predominantly acceptor-like above the CNL and a schematic band diagram is developed to substantiate the same...

Both membrane-proximal and truncation mutations in CSF3R have recently been reported to drive the onset of chronic neutrophilic leukemia (CNL). Here we show that although truncation mutation alone cannot induce leukemia, both proximal and compound mutations (proximal and truncation mutations on same allele) are leukemogenic with a disease latency of 90 and 23 days, respectively. Comparative whole-genome expression profiling and biochemical experiments revealed that induced expression of Mapk adaptor protein Ksr1 and enhanced Mapk signaling are crucial to leukemogenesis by CSF3R proximal and compound mutants...
