Overexpression of the multifunctional growth factor transforming growth factor-beta 1 (TGF beta 1) has been connected to numerous diseases in human. TGF beta 1 expression is largely governed by three AP-1 binding sites located in two different promoters of this gene. We have examined the ability of retinoid receptors to inhibit the activity of the two(More)
The benefits of treatment with antiviral therapy for severe adenovirus (AdV) pneumonia are not well established. We described the clinical characteristics and treatment outcomes of early cidofovir treatment of severe AdV pneumonia in non-immunocompromised patients. We retrospectively reviewed the medical records of all patients diagnosed with severe AdV(More)
Thoracic ultrasound (TUS) is an easy-to-use imaging modality that aids physicians in the differential diagnosis of respiratory diseases. However, no data exist on the TUS findings of acute eosinophilic pneumonia (AEP) or their clinical utility in patients with AEP. Thus, we performed an observational study on TUS findings and their clinical utility for(More)
The nucleocapsid (NC) protein of the human immunodeficiency virus-1 (HIV-1) plays an important role in the encapsidation of viral RNA and assembly of viral particle. Since the NC protein is resistant for mutation, it might be an excellent target for the anti-viral therapy. RNA aptamers that bind to the mature form of the NC protein were isolated from a RNA(More)
Samul extract, containing Radix Rehmanniae, Radix Angelicae Gigantis, Radix Paeoniae, and Rhizoma Cnidii, has been traditionally used for treatment of ischemic heart and brain damages in Oriental medicine. However, little is known about the mechanism by which Samul rescues cells from cytotoxic damage. This study was designed to investigate the protective(More)
Modulation of Sp1 activity by nuclear receptors is a novel mechanism by which fat-soluble hormones regulate gene expression. We previously established that upon autoinduction of RARs by RA, RARs/RXRs physically interact with Sp1, potentiate Sp1 binding to the GC box motifs, and thus enhance transactivation of the urokinase promoter, which lacks a canonical(More)
Acquired resistance to endocrine therapy represents a major clinical obstacle to the successful management of estrogen-dependent breast cancers expressing estrogen receptor alpha (ERalpha). Because a switch from ligand-dependent to ligand-independent activation of ERalpha-regulated breast cancer cell growth and survival may define a path to endocrine(More)
Rapid and simple analysis for the multiple target pathogens is critical for patient management. CE-SSCP analysis on a microchip provides high speed, high sensitivity, and a portable genetic analysis platform in molecular diagnostic fields. The capability of separating ssDNA molecules in a capillary electrophoretic microchannel with high resolution is a(More)
PURPOSE Endoscopic submucosal dissection has recently been practiced on a differentiated type of early gastric cancer. However, there is no clear evidence for endoscopic treatments of signet ring cell carcinoma. The aim of this study is to identify the predictive clinicopathological factors for lymph node metastasis in signet ring cell carcinoma for(More)
Polycyclic aromatic hydrocarbons, such as benzo(a)pyrene (BaP), are widespread in the environment and cause untoward effects, including carcinogenesis, in mammalian cells. However, the molecular mechanism of apoptosis by BaP is remained to be elusive. Pharmacological inhibition of p38 kinase markedly inhibited the BaP-induced cytotoxicity, which was proven(More)
