Human papillomaviruses (HPVs) are small DNA tumor viruses that are the causative agent of warts and are associated with many anogenital cancers. The viral gene encoding the E6 protein has been found to be involved in HPV oncogenesis. E6 is known to inactivate the cellular tumor suppressor, p53. In addition, E6 has been shown to bind to a variety of other(More)
Respiratory syncytial virus (RSV) is the leading cause of lower respiratory tract infections in infants and young children. However, the majority of RSV-infected patients only show mild symptoms. Different severities of infection and responses among the RSV-infected population indicate that epigenetic regulation as well as personal genetic background may(More)
Isoflurane, a commonly used volatile anesthetic, causes widespread neuronal apoptosis in the developing brain of rodents. Signal transducer and activator of transcription-3 (STAT3) signaling is crucial for cell survival during the neural network establishment period. The aim of this study was to determine whether isoflurane would target STAT3 to deliver its(More)
Puerarin, a major active isoflavone extracted from the root of Pueraria lobate, significantly increases plasma β-endorphin and insulin levels and improves impaired insulin signaling in diabetic animals. However, the target tissues and underlying mechanisms in and through which puerarin functions to ameliorating insulin resistance remains largely unclear. In(More)
BACKGROUND Human head and neck squamous cell carcinoma (HNSCC) is the sixth most malignant cancer worldwide. Despite significant advances in the delivery of treatment and surgical reconstruction, there is no significant improvement of mortality rates for this disease in the past decades. Radiotherapy is the core component of the clinical combinational(More)
BACKGROUND Acute exacerbation of idiopathic pulmonary fibrosis (AE-IPF) has high short-term mortality with unknown causes. To predict this malignant condition in clinics is challenging. In this study, we aim to demonstrate whether there are miRNAs that differ between AE-IPF and stable IPF, which may be served as reliable biomarker for AE-IPF prediction. (More)
Isoflurane exposure induces apoptosis in cultured cells and in the developing brain, while the underlying mechanism remains largely unclarified. This study was designed to determine whether the disruption of mitoKATP-mediated ATP balance was involved in the cytotoxicity of isoflurane. Human neuroglioma cells U251 and 7-day-old mice were treated with(More)
The antitumor effect of luteolin, a plant flavonoid, in gastric cancer (GC) cells has not been fully understood. Here we show that luteolin selectively kills STAT3 overactivated GC cells that are often drug resistant. The treatment of luteolin in these GC cells significantly inhibited STAT3 phosphorylation and reduced the expression of STAT3 targeting gene(More)
TO THE EDITOR Sirtuin 1 (SIRT1), an NAD-dependent deacetylase (Imai et al., 2000), acts as a metabolic sensor that functions on both histone and non-histone proteins (Leibiger and Berggren, 2006; Li, 2013). In this study, we find that SIRT1 activation in animals could inhibit Aldarainduced psoriasiform lesions. Moreover, SIRT1–STAT3 interaction may serve as(More)
Heme oxygenase-1 (HO-1), a stress-inducible protein with a potential anti-inflammatory effect, plays an important role in skin injury and wound healing. However, the function of HO-1 in cutaneous inflammatory diseases, such as psoriasis, remains unknown. The abnormal activation of Stat3, a known transcription factor that induces inflammation and regulates(More)
