Hypoxia-Immune-Related Gene SLC19A1 Serves as a Potential Biomarker for Prognosis in Multiple Myeloma.

Background: Multiple myeloma (MM) remains an incurable malignant tumor of plasma cells. Increasing evidence has reported that hypoxia and immune status contribute to the progression of MM. In this research, the prognostic value of the hypoxia-immune-related gene SLC19A1 in MM was evaluated by bioinformatics analysis.

iTRAQ-based quantitative proteomic analysis of the hepatopancreas in Scylla paramamosain during the molting cycle.

The hepatopancreas is the key organ involved in energy storage, immune response, and metabolism during crustacean molting, yet the underlying molecular mechanisms in the hepatopancreas that regulate molting remain unknown. In the present study, we conducted a comprehensive proteomic analysis in the hepatopancreas and quantified 1527 proteins, of which 193 changed significantly in abundance among three molting stages (pre-molt: PrM, post-molt: PoM, and inter-molt: InM) of Scylla paramamosain using iTRAQ-coupled LC-MS/MS. Ten exoskeleton and cuticle reconstruction proteins, such as chitinase, cuticle protein and myosin heavy chain, were found change significantly in abundance between PoM and PrM.

Hyperfibrinolysis Is an Important Cause of Early Hemorrhage in Patients with Acute Promyelocytic Leukemia.

BACKGROUND The objective of the current study was to guide the early clinical treatment strategies by assessing the recovery of abnormal coagulation in acute promyelocytic leukemia (APL) patients during induction therapy. MATERIAL AND METHODS Retrospective analysis was performed in 112 newly-diagnosed patients with APL during induction treatment. RESULTS The early death (ED) rate in our study was 5.

Sequencing and comparative analyses of Aegilops tauschii chromosome arm 3DS reveal rapid evolution of Triticeae genomes.

Bread wheat (Triticum aestivum, AABBDD) is an allohexaploid species derived from two rounds of interspecific hybridizations. A high-quality genome sequence assembly of diploid Aegilops tauschii, the donor of the wheat D genome, will provide a useful platform to study polyploid wheat evolution. A combined approach of BAC pooling and next-generation sequencing technology was employed to sequence the minimum tiling path (MTP) of 3176 BAC clones from the short arm of Ae.

Novel dynamin 2 mutations in adult T-cell acute lymphoblastic leukemia.

Genetic mutations on signaling pathways are found in patients with T-cell acute lymphoblastic leukemia (T-ALL) and act as markers of high-risk leukemia. Mutations in dynamin 2 (DNM2) have been reported in T-ALL, particularly in early T-cell precursor-ALL. In the present study, DNM2 mutations were screened by sequencing DNM2 exons obtained by polymerase chain reaction amplification and gel purification in adult T-ALL patients.

[Mutation of IL-7R in Adult Patients with T-cell Acute Lymphoblastic Leukemia and Its Clinical Significance].

Objective: Interleukin 7 (IL-7) and its receptor（IL-7R）are essential for normal T-cell development and homeostasis. This study was aimed to investigate the IL-7R mutation and its clinical significance in adult patients with adult acute lymphoblastic leukemia (ALL), particularly in T-ALL.

Methods: The exons of IL-7R were amplified, cloned and sequenced in 144 adult patients with ALL; the frequency, position and lypes of IL-7R mutation were detected and their correlation with clinical features was analyzed.

Co-existence of and mutations in adult T-cell acute lymphoblastic leukemia.

T-cell acute lymphoblastic leukemia (T-ALL) results from the collaboration of multiple genetic abnormalities in the transformation of T-cell progenitors. Plant homeodomain finger protein 6 () has recently been established as a key tumor suppressor, which is mutated in T-ALL; however, the clinical significance of mutations has not been fully determined in adult T-ALL. In the present study, amplification of the exons was performed, followed by DNA sequencing to identify the genomic mutations and examine the expression of in adult patients with T-ALL.

Co-existence of IL7R high and SH2B3 low expression distinguishes a novel high-risk acute lymphoblastic leukemia with Ikaros dysfunction.

Acute lymphoblastic leukemia (ALL) remains the leading cause of cancer-related death in children and young adults. Compared to ALL in children, adult ALL has a much lower cure rate. Therefore, it is important to understand the molecular mechanisms underlying high-risk ALL and to develop therapeutic strategies that specifically target genes or pathways in ALL.

[Analysis of CALR, JAK2 and MPL gene mutations in BCR-ABL negative myeloproliferative neoplasms].

Objective: To explore the mutational status of CALR, JAK2 and MPL genes in BCR-ABL negative myeloproliferative neoplasms (MPN) patients and the clinical features of MPN patients with these mutations.

Methods: A total of 246 patients with a definite diagnosis of BCR-ABL negative MPN were enrolled from January 2009 to January 2014 into this study. Among them, there were 48 cases of polycythemia vera (PV) patients, 171 cases of essential thrombocythemia (ET) patients and 27 cases of primary myelofibrosis (PMF) patients.

Characterization of HKI-272 covalent binding to human serum albumin.

The study was initiated as an observation of incomplete extraction recovery of N-(4-(3-chloro-4-(2-pyridinylmethoxy)anilino)-3-cyano-7-ethoxy-6-quinolyl)-4-(dimethylamino)-2-butenamide (HKI-272) from human plasma. The objective of this study was to 1) identify the binding site(s) of HKI-272 to human plasma protein(s); 2) characterize the nature of the binding; and 3) evaluate the potential reversibility of the covalent binding. After incubation of [(14)C]HKI-272 with human plasma, the mixture was directly injected on liquid chromatography/mass spectrometry (LC/MS), and an intact molecular mass of HKI-272 human serum albumin (HSA) adduct was determined to be 66,999 Da, which is 556 Da (molecular mass of HKI-272) larger than the measured molecular mass of HSA (66,443 Da).
