Previously, we and others showed that mitotic Aurora-A kinase (Aur-A) was required for accurate mitotic entry and proper spindle assembly. In this study, we found that expression of Aur-A was markedly elevated in bone marrow mononuclear cells (BMMCs) obtained from a significant portion of de novo acute myeloid leukemia (AML) patients. Targeting human(More)
Oxytocin (OT), a neurohypophyseal neuropeptide, affects adaptive processes of the central nervous system. In the present study, we investigated the effects of OT on extracellular levels of glutamate (Glu) and γ-aminobutyric acid (GABA) induced by methamphetamine (MAP) in the medial prefrontal cortex (mPFC) and dorsal hippocampus (DHC) of freely moving mice,(More)
AIM To investigate the resistance of Helicobacter pylori (H. pylori) to ciprofloxacin (CIP), levofloxacin (LVX) and moxifloxacin (MOX) in the Beijing area and to elucidate the resistance mechanisms. METHODS Seventy-nine H. pylori clinical strains, isolated from patients who had undergone upper gastrointestinal endoscopy in Peking University First Hospital(More)
Sonic Hedgehog (Shh) plays an essential role in vertebrate organogenesis as well as the development of some cancers, including breast cancer. The aim of the present study was to characterize more precisely its role in breast carcinogenesis and elucidate its regulation mechanisms. The expression of Shh was investigated in 97 breast carcinomas and 22 paired(More)
The mitotic Aurora-A kinase exerts crucial functions in maintaining mitotic fidelity. As a bona fide oncoprotein, Aurora-A aberrant overexpression leads to oncogenic transformation. Yet, the mechanisms by which Aurora-A enhances cancer cell survival remain to be elucidated. Here, we found that Aurora-A overexpression was closely correlated with clinic stage(More)
The mitotic kinase Aurora-A (Aur-A) is required to form the bipolar spindle and ensure accurate chromosome segregation before cell division. Aur-A dysregulation represents an oncogenic event that promotes tumor formation. Here, we report that Aur-A promotes breast cancer metastasis. Aur-A overexpression enhanced mammary cell migration by dephosphorylation(More)
PURPOSE CD99 is a cell adhesion molecule associated with human tumors. The aim of the present study was to characterize its role in the development and progression of human gastric adenocarcinoma. EXPERIMENTAL DESIGN The expression of CD99 was investigated in 283 gastric adenocarcinomas and related lesions and 9 gastric carcinoma cell lines. We also(More)
The inhibitory effects of 21 resveratrol derivatives on lipopolysaccharide (LPS)-induced nitric oxide (NO) production in microglia and their structure-activity relationships were studied. It was found, for the first time, that certain resveratrol derivatives that have 3,5-dimethoxyl groups in the A-ring, such as (E)-4-(3,5-dimethoxystyryl)phenol(More)
AIMS The expression patterns of TGFB signaling proteins, such as TGFB1/2, TGFBR1(ALK5), TGFBR2, SMAD1/2/3, SMAD2/3, SMAD4, SMAD7, and of downstream targets of TGFB signaling, CDKN1A (p21CIP1), CDKN1B (p27KIP1), MYC, CDC25A, TP53, and RELA (p65NF-kB) were investigated in gastric carcinomas and other gastric lesions. METHODS AND RESULTS A total of 112(More)
PURPOSE We investigate the value of pretreatment serologic antienzyme rate (AER) of Epstein-Barr virus (EBV) DNase-specific neutralizing antibody complementing TNM staging in prognostication of nasopharyngeal carcinoma (NPC). PATIENTS AND METHODS Pretreatment serum samples from 1,303 patients with untreated NPC were collected and examined for AER. After a(More)
