Antibiotic-resistance by bacteria is a growing global concern within the healthcare field, and it has provided an impetus for continued antimicrobial development. Pyrinezolid (PZ), a novel oxazolidinone compound, can effectively inhibit most gram-positive bacteria, including methicillin-resistant Staphylococcus aureus (MRSA) and vancomycin-resistant Enterococci (VRE). Though PZ is a promising antimicrobial candidate, the druggability of PZ is limited by its poor water solubility. Therefore, the amphipathic mPEG-PLLA copolymer was used to prepare the pyrinezolid micelles (PZ-M)...

TRAF family member-associated NF-κB activator (TANK)-binding kinase1 (TBK1) is a serine-threonine kinase at the crossroads of multiple interferon (IFN)-inducing signaling pathways in innate immunity. The importance of TBK1 in antiviral immunity is well established in mammal models, but in chicken, the molecular characterization and potential function of TBK1 remain unclear. In the present study, the open-reading frame (ORF) of chicken TBK1 (chTBK1) was cloned and characterized. The sequencing results revealed that the chTBK1 ORF consists of 2190 base pairs (bp) encoding a deduced protein of 729 amino acid residues...

Haemophilia A (HA) is a common X-linked recessive bleeding disorder and almost one half of patients with severe HA are caused by intron 22 inversion (Inv22) in the F8. Inv22 is considered to be almost exclusively of meiotic origin in germ cells during spermatogenesis and only one mosaic Inv22 female carrier with the mutation possibly occurring during mitosis of the embryo has been reported so far. Previously we have identified a novel complex recombination mediated by int22h copies in a sporadic severe HA pedigree and herein we have localised the sequences flanking the breakpoint region using genome walking technique, AccuCopy technique, gene chip and real-time PCR...

RATIONALE: Hereditary neuropathy with liability to pressure palsy (HNPP) is an episodic, multifocal neuropathy, with a typical clinical presentation of recurrent transient pressure palsies, which is induced by a PMP22 deletion. Another neuropathy caused by a PMP22 duplication is Charcot-Marie-Tooth disease type 1A (CMT1A). PMP22 is a gene coding a protein called peripheral myelin protein 22 (PMP22), which plays an essential role in the formation and maintenance of compact myelin. Coexistence of type 2 diabetes mellitus (T2DM) and CMT1A has been reported in many work, however HNPP patients with T2DM are rare, and comorbidity of HNPP and psoriasis has not been reported previously...

Histone deacetylase inhibitors have been identified for the treatment of cancer. Lately, we designed and synthesized a series of substituted N-benzylpyrimidin-2-amine derivatives as potent HDAC inhibitors. In vitro HDAC inhibitory activities and anti-proliferative activities of target compounds were investigated. Some target compounds showed potent HDAC inhibitory activities and possessed obvious anti-proliferative activity against tumor cells. Target compounds 6a, 6d, 8a, 8c and 8f not only exhibited almost equally enzymatic inhibitory activity with SAHA, but showed better anti-proliferative activities...

Pancreatic neuroendocrine carcinoma (PNEC) is often misdiagnosed as pancreatic ductal adenocarcinoma (PDAC). This retrospective study differentiated PNEC from PDAC using magnetic resonance imaging (MRI), including contrast-enhanced (CE) and diffusion-weighted imaging (DWI). Clinical data and MRI findings, including the T1/T2 signal, tumor boundary, size, enhancement degree, and apparent diffusion coefficient (ADC), were compared between 37 PDACs and 13 PNECs. Boundaries were more poorly defined in PDAC than PNEC (97...

Glioblastoma multiforme (GBM) is a highly invasive brain tumor with limited therapeutic means and poor prognosis. Recent studies indicate that glioma-initiating cells/glioma stem cells (GICs/GSCs) may be responsible for tumor initiation, infiltration, and recurrence. GICs could aberrantly employ molecular machinery balancing self-renewal and differentiation of embryonic neural precursors. Here, we find that paired related homeobox 1 (PRRX1), a homeodomain transcription factor that was previously reported to control skeletal development, is expressed in cortical neural progenitors and is required for their self-renewal and proper differentiation...

DNA N(6)-methyl-2'-deoxyadenosine (6mdA) is an epigenetic modification in both eukaryotes and bacteria. Here we exploited stable isotope-labeled deoxynucleoside [(15)N5]-2'-deoxyadenosine ([(15)N5]-dA) as an initiation tracer and for the first time developed a metabolically differential tracing code for monitoring DNA 6mdA in human cells. We demonstrate that the initiation tracer [(15)N5]-dA undergoes a specific and efficient adenine deamination reaction leading to the loss the exocyclic amine (15)N, and further utilizes the purine salvage pathway to generate mainly both [(15)N4]-dA and [(15)N4]-2'-deoxyguanosine ([(15)N4]-dG) in mammalian genomes...

Crizotinib has been used to counter MET gene amplification in a number of different human malignancies. Transient response to crizotinib in MET-amplified gastric cancer has been reported, but the mechanisms of resistance are not well studied. Here, we reported a stage IV gastric cancer patient with high levels of MET amplification. The implementation of crizotinib treatment led to significant symptomatic improvement in the first 2 months, but was followed by rapid disease progression. Periodic mutation profiling of patient's circulating tumor DNA (ctDNA) by next generation sequencing (NGS) revealed a number of genetic alterations including re-occurrence of MET amplification, multiple secondary MET mutations, a dramatic increase of FGFR2 gene relative copy number as well as mutations in other downstream and bypassing elements, which may collectively related to the patient's cancer progression...
