BACKGROUND Serotype 19A invasive pneumococcal disease (IPD) increased annually in the United States after the introduction of the 7-valent conjugate vaccine (PCV7). To understand this increase, we characterized serotype 19A isolates recovered during 2005. METHODS IPD cases during 1998-2005 were identified through population-based surveillance. We performed susceptibility testing and multilocu...
miRNAs have been implicated in processing of cardiac hypoxia/reoxygenation (H/R)-induced injury. Recent studies demonstrated that miR-19a might provide a potential cardioprotective effect on myocardial disease. However, the effect of miR-19a in regulating myocardial ischemic injury has not been previously addressed. The present study was to investigate the effect of miR-19a on myocardial ischem...
A novel lymphocyte-specific immunoglobulin superfamily protein (19A) has been cloned. The predicted 335-amino-acid sequence of 19A represents a Type 1 membrane protein with homology with the CD2 family of receptors. A molecular model of the two predicted extracellular immunoglobulin-like domains of 19A has been generated using the crystal structure of CD2 as a template. In isolated lymphocytes,...
Activation of mTOR complex 1 (mTORC1) could protect human osteoblasts from dexamethasone. Tuberous sclerosis complex 1 (TSC1) is mTORC1 upstream inhibitory protein. We demonstrate here that microRNA-19a ("miR-19a", -3p) targets the 3' untranslated regions of TSC1 mRNA. Expression of miR-19a downregulated TSC1 in OB-6 osteoblastic cells and primary human osteoblasts. miR-19a activated mTORC1 and...
Increasing evidence has shown that microRNA (miRNA) is extensively involved in the pathophysiology of lung cancer. Microarray data demonstrated the increasing levels of miR-19a in the peripheral blood from patients suffering from lung cancer, which is closely associated with poor prognosis of lung cancer. However, the underlying molecular mechanism of miR-19a remains to be determined. The resul...
In gastric carcinoma, the nuclear factor‑κB (NF‑κB) signaling pathway is highly active, and the constitutive activation of NF‑κB prompts malignant cell proliferation. MicroRNAs are considered to be important mediators in the regulation of the NF‑κB signaling pathway. The present study predominantly focussed on the effects of microRNA (miR)‑19a on NF‑κB activation. Reverse transcription‑quantita...
BACKGROUND The Streptococcus pneumoniae serotype 19A sequence type (ST) 320 clone, derived from an international Taiwan(19F)-14 (ST236) clone, has become prevalent in many countries. METHODS The dynamics of invasive pneumococcal disease (IPD) were determined using the database of the National Notifiable Disease Surveillance System in Taiwan. The virulence of 19A ST320 and Taiwan(19F)-14 (ST23...
BACKGROUND The application of microRNAs (miRNAs) as potential biomarkers and therapy targets has been widely investigated in many kinds of cancers. The discovery of tumor associated miRNAs in serum of patients supported the use of plasma/serum miRNAs as noninvasive means of cancer detection. However, the aberrant expression of miRNAs in bladder cancer patients and their intensive roles and mech...
PURPOSE We aimed to investigate whether miR-19a is associated with neuropathic pain and elucidate the underlying regulatory mechanism. METHODS We established a neuropathic pain model of bilateral chronic constriction injury (bCCI). Then bCCI rats were injected with mo-miR-19a, siR-SOCS1 or blank expression vector through a microinjection syringe via an intrathecal catheter on 3 day before sur...
Pterostilbene (Pter) is reported to exhibit an anticancer effect in hepatocellular carcinoma (HCC). In order to explore the anticancer mechanism in HCC cells, the present study aimed to investigate whether pterostilbene (Pter) may increase phosphatase and tensin homolog (PTEN) expression through targeted downregulation of microRNA (miRNA/miR)-19a in hepatocellular carcinoma (HCC). The prolifera...
