We screened a total of 672 plant-tissue extracts to search for phytochemicals that inhibit the function of the type III secretion system (T3SS) of enteropathogenic Escherichia coli (EPEC) and enterohemorrhagic E. coli (EHEC). Among candidates examined, we found that an extract from the leaves of Psidium guajava (guava) inhibited the secretion of the EspB protein from EPEC and EHEC without affecting bacterial growth. The guava extract (GE) also inhibited EPEC and EHEC from adhering to and injecting EspB protein into HEp-2 cells...

In organ fibrosis, mechanical stress and transforming growth factor beta-1 (TGF-β1) promote differentiation into myofibroblast from mesenchymal cells, leading to extracellular matrix (ECM) remodeling or active synthesis, deposition or degradation of ECM components. A major component of ECM, type I collagen (col I) triple helical molecules assemble into fibrils or are denatured to gelatin without triple-helicity in remodeling. However, whether changes of ECM components in remodeling have influence on mesenchymal cell differentiation remains elusive...

Reactive oxygen species (ROS) participate in various cell responses in association with cell proliferation, migration, differentiation and death. Extracellular matrix (ECM) serves as cellular microenvironments for many kinds of cells, affecting cell activities. However, whether or not ECM influences cellular ROS levels has not been well studied. In this study, cells are cultured on collagen I molecule-coated (mol. coated) dishes and collagen I fibrous gel-covered (gel) dishes to explore their influence on cell behaviors...

Dysregulation of cell metabolism is a hallmark of cancer. The mevalonate pathway in lipid metabolism has been implicated as a potential target of cancer therapy for hepatocellular carcinoma (HCC). The role of the Forkhead Box M1 (FoxM1) transcription factor in HCC development has been well documented, however, its involvement in cancer metabolism of HCC has not been fully determined. Here, we hypothesized that FoxM1 is involved in the mevalonate pathway of cholesterol biosynthesis in HCC. Inhibition of the mevalonate pathway by statins, inhibitors of 3-hydroxy-3-methylglutaryl CoA reductase (HMGCR), resulted in reduced expression of FoxM1 and increased cell death in human hepatoma cells...

To prevent early neurological worsening or recurrence in stroke patients with intracranial arterial stenosis or branch atheromatous disease, aggressive antithrombotic therapy, such as dual antiplatelet therapy (DAPT) with or without anticoagulant therapy, is warranted. Such an aggressive antithrombotic therapy, however, may increase the bleeding risk. We studied the risks of DAPT with the anticoagulant argatroban in patients with acute ischemic stroke or transient ischemic attack (TIA). Between October 2011 and September 2015, 341 patients with stroke or TIA, who received DAPT with argatroban within 48 hours after onset, were retrospectively studied...

A woman in her 70s with an 8.6-cm tumor in the anterior mediastinum underwent tumor excision by median sternotomy, which combined resection of the fifth and sixth ribs. The pathological diagnosis was myxofibrosarcoma, and pathologically curative resection was accomplished. Local recurrence was detected at 10, 19, 23 and 28 months after the initial surgery. After repeated surgical resection, radiation therapy for the fourth unresectable recurrence resulted in failure. She died 34 months after the initial surgery...

OBJECTIVE: Reverse cholesterol transport (RCT) is a major mechanism by which HDL (high-density lipoprotein) protects against atherosclerosis. Endothelial lipase (EL) reportedly reduces HDL levels, which, in theory, would increase atherosclerosis. However, it remains unclear whether EL affects RCT in vivo. APPROACH AND RESULTS: Adenoviral vectors expressing EL or luciferase were intravenously injected into mice, and a macrophage RCT assay was performed. As expected, hepatic EL overexpression markedly reduced HDL levels...

In mammals, spermatozoa activate oocytes by triggering a series of intracellular Ca2+ oscillations with phospholipase C zeta (PLCζ), a sperm-borne oocyte-activating factor. Because the introduction of PLCζ alone can induce oocyte activation, it might be a promising reagent for assisted reproductive technologies. To test this possibility, we injected human PLCζ (hPLCζ) mRNA into mouse oocytes at different concentrations. We observed the oocyte activation and subsequent embryonic development. Efficient oocyte activation and embryonic development to the blastocyst stage was achieved only with a limited range of mRNA concentrations (0...
