Legionella pneumophila is a Gram-negative, flagellated bacterium that survives in phagocytes and causes Legionnaires' disease. Upon infection of mammalian macrophages, cytosolic flagellin triggers the activation of Naip/NLRC4 inflammasome, which culminates in pyroptosis and restriction of bacterial replication. Although NLRC4 and caspase-1 participate in the same inflammasome, Nlrc4-/- mice and...
After ingestion by macrophages, Legionella pneumophila enter spacious vacuoles that are quickly enveloped by endoplasmic reticulum (ER), then slowly transferred to lysosomes. Here we demonstrate that the macrophage autophagy machinery recognizes the pathogen phagosome as cargo for lysosome delivery. The autophagy conjugation enzyme Atg7 immediately translocated to phagosomes harbouring virulent...
BACKGROUND Oxymatrine, an isolated extract from traditional Chinese herb Sophora Flavescens Ait, has been traditionally used for therapy of anti-hepatitis B virus, anti-inflammation and anti-anaphylaxis. The present study was to investigate the anti-cancer effect of oxymatrine on human pancreatic cancer PANC-1 cells, and its possible molecular mechanism. METHODS The effect of oxymatrine on th...
Estimates of riparian vegetation water use are important for hydromorphological assessment, partitioning within human and natural environments, informing environmental policy decisions. The objectives this study were to calculate the actual evapotranspiration (ETa) (mm/day mm/year) derive annual consumptive (CU) in acre-feet (AF) select areas Little Colorado River watershed Navajo Nation, north...
BACKGROUND We report a case of a neonate with proximal spinal muscular atrophy (SMA) type 1 (also known as Werdnig-Hoffmann disease or severe infantile acute SMA) associated with a Blake's pouch cyst; a malformation that is currently classified within the spectrum of Dandy-Walker complex. The association of the two conditions has not been previously reported in the English literature. A compreh...
A comparative genomic approach was used to reconstruct transcriptional regulation of NAD biosynthesis in bacteria containing orthologs of Bacillus subtilis gene yrxA, a previously identified niacin-responsive repressor of NAD de novo synthesis. Members of YrxA family (re-named here NiaR) are broadly conserved in the Bacillus/Clostridium group and in the deeply branching Fusobacteria and Thermot...
Amyotrophic lateral sclerosis (ALS) is an adult-onset motor neuron degenerative disease. Given that oxidative stress and resulting chronic neuronal inflammation are thought to be central pathogenic, anti-oxidative agents and modulators of neuronal inflammation could be potential therapies for ALS. We report here that the novel small molecular compound, 2-[mesityl(methyl)amino]-N-[4-(pyridin-2-y...
Apoptosis is a process, which involves a sequence of cellular changes, which ultimately lead to cell death. This programmed cell death is a normal phenomenon required for growth of an organism. Inhibition of apoptosis can result in a number of cancers, inflammatory and autoimmune diseases and viral infections. Inhibitors of apoptosis proteins (IAPs) are a family of structurally and functionally...
