Upfront Androgen Receptor-Axis-Targeted Therapies in Men with De Novo High-Volume Metastatic Hormone-Sensitive Prostate Cancer.

Purpose: The extent of effectiveness of upfront androgen receptor-axis-targeted therapies (ARAT) versus total androgen blockade (TAB) in improving prostate cancer-specific survival (CSS) and progression-free survival (PFS) in a real-world sample of Japanese patients with high-volume mHSPC remains unclear. We, therefore, investigated the efficacy and safety of upfront ARAT versus bicalutamide for de novo high-volume mHSPC in Japanese patients.

Material And Methods: This was a multicenter retrospective study that analyzed CSS, clinical PFS, and adverse events (AEs) in 170 patients with newly diagnosed high-volume mHSPC.

Histological Transformation to Large Cell Neuroendocrine Carcinoma from Lung Adenocarcinoma Harboring an EGFR Mutation: An Autopsy Case Report.

We herein report a 58-year-old Japanese woman who survived 14 years after surgery for lung adenocarcinoma harboring an epidermal growth factor receptor (EGFR) exon 19 deletion. She developed recurrence, for which she underwent multimodal therapy, including EGFR-tyrosine kinase inhibitor (TKI) administration. She ultimately died from a rapidly progressive right lung tumor that was resistant to EGFR-TKI.

Synthetic Assembly of Mannose Moieties Using Polymer Chemistry and the Biological Evaluation of Its Interaction towards Concanavalin A.

Protein-carbohydrate interactions exhibit myriad intracellular recognition events, so understanding and investigating their specific interaction with high selectivity and strength are of crucial importance. In order to examine the effect of multivalent binding on the specificity of protein-carbohydrate interactions, we synthesized mannose glycosides as a novel type of glycosylated monomer and glycopolymers of polyacrylamide derivatives with α-mannose (α-Man) by radical polymerization and monitored their strength of interaction with concanavalin A (Con A) by surface plasmon resonance (SPR) detection. In a quantitative test using the Con A-immobilized sensor surface, the kinetic affinity for the synthesized polymers, ( = 3.

Cyanide-bridged decanuclear cobalt-iron cage.

A cyanide-bridged decanuclear [Co6Fe4] cluster was synthesized by a one-pot reaction, and the magnetic properties and electronic configuration were investigated. The complex displayed thermally controlled electron-transfer-coupled spin transition (ETCST) behavior between Co(III) low-spin-NC-Fe(II) low-spin and Co(II) high-spin-NC-Fe(III) low-spin states, as confirmed by single-crystal X-ray, magnetic, and Mössbauer analyses.

Retrospective investigation of the clinical effects of tazobactam/piperacillin and sulbactam/ampicillin on aspiration pneumonia caused by Klebsiella pneumoniae.

Klebsiella pneumoniae is an important causative bacterium of aspiration pneumonia in many elderly patients. We retrospectively investigated the clinical effects of the early treatment of aspiration pneumonia and background factors in 24 patients from whom Klebsiella pneumoniae was isolated. Sulbactam/ampicillin (SBT/ABPC) was selected for early treatment in 12 of the 24 patients diagnosed with aspiration pneumonia, and tazobactam/piperacillin (TAZ/PIPC) was selected for the other patients.

Henoch Schönlein purpura associated with pulmonary adenocarcinoma.

Introduction: Henoch-Schönlein purpura is a common immunoglobulin A-mediated vasculitis syndrome in children. Henoch-Schönlein purpura can also affect adults and is probably related to malignancy.

Case Presentation: We report the case of a 61-year-old Japanese man who presented for examination after an abnormal shadow was detected by chest radiography.

Genes outside the S supergene suppress S functions in buckwheat (Fagopyrum esculentum).

Background And Aims: Common buckwheat (Fagopyrum esculentum) is a dimorphic self-incompatible plant with either pin or thrum flowers. The S supergene is thought to govern self-incompatibility, flower morphology and pollen size in buckwheat. Two major types of self-fertile lines have been reported.

RNA helicase A interacts with nuclear factor kappaB p65 and functions as a transcriptional coactivator.

RNA helicase A (RHA), a member of DNA and RNA helicase family containing ATPase activity, is involved in many steps of gene expression such as transcription and mRNA export. RHA has been reported to bind directly to the transcriptional coactivator, CREB-binding protein, and the tumor suppressor protein, BRCA1, and links them to RNA Polymerase II holoenzyme complex. Using yeast two-hybrid screening, we have identified RHA as an interacting molecule of the p65 subunit of nuclear factor kappaB (NF-kappaB).

Visualization of a functional KSHV episome-maintenance protein LANA in living cells.

The latency-associated nuclear antigen (LANA) of Kaposi's saroma-associated herpesvirus (KSHV) can maintain a plasmid containing the KSHV origin of DNA replication (oriP) as episomes in dividing human cells. Hence, LANA is considered to play crucial roles in persistent KSHV infection in human cells. In this study, we characterized a LANA fusion protein of green fluorescent protein (GFP-LANA).

Identification of AFLP makers linked to non-seed shattering locus (sht1) in buckwheat and conversion to STS markers for marker-assisted selection.

Shattering habit in buckwheat has two forms: brittle pedicel and weak pedicel. Brittle pedicel is observed in wild buckwheat, but not in cultivated buckwheat. Brittle pedicel in buckwheat is produced by two complementary, dominant genes, Sht1 and Sht2.

Latency-associated nuclear antigen of Kaposi's sarcoma-associated herpesvirus interacts with human myeloid cell nuclear differentiation antigen induced by interferon alpha.

Kaposi's sarcoma-associated herpesvirus (KSHV)/human herpes virus type 8 (HHV-8) is tightly linked to the development of Kaposi's sarcoma, primary effusion lymphoma (PEL) and some cases of multicentric Castleman's disease. Latency-associated nuclear antigen (LANA) is one of a limited number of KSHV genes consistently expressed in these diseases as well as in KSHV-infected cell lines derived from PEL, and has been shown to play crucial role in persistence of KSHV genomes in the infected cells. In this study, we explored the cellular factors that interact with LANA using yeast two-hybrid screening, and isolated a part of gene encoding human myeloid cell nuclear differentiation antigen (MNDA).

Induction of Notch signaling by tumor necrosis factor in rheumatoid synovial fibroblasts.

Rheumatoid arthritis (RA) is characterized by progressive inflammation associated with abberrant proliferation of synoviocytes. In order to explore the characteristics of rheumatoid synovial fibroblasts (RSF), we performed the comparative gene expression profile analysis between RSF and normal synovial fibroblasts (NSF) upon tumor necrosis factor (TNF) stimulation. As an initial screening for the genes preferentially induced by TNF in RSF compared with NSF, we have adopted a cDNA array containing well-defined sets of genes responsible for cell growth, cell fate determination, and cellular invasiveness.

Heteromorphic incompatibility retained in self-compatible plants produced by a cross between common and wild buckwheat.

•   Common buckwheat (Fagopyrum esculentum) is a dimorphic self-incompatible plant with either a pin or a thrum flower. It is considered that self-incompatibility, flower morphology, and pollen size are governed by the S supergene. •   Here, we produced self-compatible buckwheat lines by an interspecific cross between F.

3-methylcholanthrene activates human immunodeficiency virus type 1 replication via aryl hydrocarbon receptor.

We found that 3-methylcholanthrene (3-MC) could induce the reactivation of human immunodeficiency virus type 1 (HIV-1) replication in OM 10.1 cell, promyelocytic cell line latently infected with HIV-1. Transient luciferase expression experiments have revealed no particular transcription factors that are responsible for the effect of 3-MC in inducing HIV-1 gene expression as HIV-1 LTR mutants lacking various upstream transcriptional activators similarly responded to 3-MC.

RING finger protein AO7 supports NF-kappaB-mediated transcription by interacting with the transactivation domain of the p65 subunit.

In this study, a novel interactor of the p65 subunit (RelA) of NF-kappaB has been explored by performing yeast two-hybrid screen using the transactivation domain (TAD) of p65 located in the C terminus as bait. We have isolated a RING finger motif-containing protein, AO7, previously identified as an interacting protein with a ubiquitin-conjugating enzyme, Ubc5B. We confirmed the protein-protein interaction between p65 and AO7 in vitro and in vivo and found that the C-terminal region of AO7 is responsible for the interaction with p65 TAD.

NF-kappa B p65 transactivation domain is involved in the NF-kappa B-inducing kinase pathway.

NF-kappa B-inducing kinase (NIK) is involved in the signal transduction pathway leading to the NF-kappa B activation. In this report, we demonstrate that the NIK-mediated NF-kappa B activation involves the transactivation (TA) domain of p65 subunit of NF-kappa B and the nuclear translocation of IKK alpha. By using luciferase assay, we found that both IKK alpha and IKK beta could activate NF-kappa B in synergy with NIK.

The NF-kappa B activation in lymphotoxin beta receptor signaling depends on the phosphorylation of p65 at serine 536.

NF-kappaB-inducing kinase (NIK) has been shown to play an essential role in the NF-kappaB activation cascade elicited by lymphotoxin beta receptor (LTbetaR) signaling. However, the molecular mechanism of this pathway remains unclear. In this report we demonstrate that both NIK and IkappaB kinase alpha (IKKalpha) are involved in LTbetaR signaling and that the phosphorylation of the p65 subunit at serine 536 in its transactivation domain 1 (TA1) plays an essential role.

Inhibition of the NF-kappaB transcriptional activity by protein kinase A.

The cAMP-dependent protein kinase (PKA) signaling pathway plays a major role in a number of pathophysiological conditions. However, there have been conflicting evidences regarding the action of cAMP/PKA on nuclear factor- kappaB (NF-kappaB). In this study, we have explored the effect of cAMP/PKA on NF-kappaBeta activity and determined its molecular mechanism.

RelA-associated inhibitor blocks transcription of human immunodeficiency virus type 1 by inhibiting NF-kappaB and Sp1 actions.

RelA-associated inhibitor (RAI) is an inhibitor of nuclear factor kappaB (NF-kappaB) newly identified by yeast two-hybrid screen as an interacting protein of the p65 (RelA) subunit. In this study, we attempted to examine the effect of RAI on transcription and replication of human immunodeficiency virus type 1 (HIV-1). We found that RAI inhibited gene expression from the HIV-1 long terminal repeat (LTR) even at the basal level.

Inhibitory effects of IFN-gamma on HIV-1 replication in latently infected cells.

The progress in the use of HAART for the treatment of HIV-infected individuals has been limited by the development of viral resistance and the maintenance of viral latency. New therapeutic strategies geared toward improvement in the host's immune response are now being considered. We found that IFN-gamma induces CIITA through the JAK-STAT pathway and inhibits HIV-1 replication in latently infected cells.
