The mitochondrial antiviral signaling protein MAVS (IPS-1, VISA, or Cardif) plays an important role in the host defense against viral infection by inducing type I interferon. Recent reports have shown that MAVS is also critical for virus-induced apoptosis. However, the mechanism of MAVS-mediated apoptosis induction remains unclear. Here, we show that MAVS(More)
UNLABELLED Retinoic acid-inducible gene I (RIG-I) is an intracellular RNA virus sensor that induces type I interferon-mediated host-protective innate immunity against viral infection. Although cylindromatosis (CYLD) has been shown to negatively regulate innate antiviral response by removing K-63-linked polyubiquitin from RIG-I, the regulation of its(More)
Stringent control of inflammasome signaling pathway is important for maintaining immunological balance, yet the molecular mechanisms responsible for its tight regulation are still poorly understood. In this study, we found that the signaling pathway dependent on mitochondrial antiviral signaling protein (MAVS) was required for the optimal activation of(More)
Aging is a natural process accompanied with many disorders, including the memory decline. The underlying mechanisms for the age-related memory decline are complicated. Previous work suggested that oxidative stress, inflammatory disturbance, and the neurotropic absence play important roles in the age-related disorders. Thus, to seek a drug to target those(More)
Malignant astrocytomas are the most common primary brain tumors. The critical characterizes of astrocyomas are their aggressive and infiltrative in the brain, which leads to uncontrollable by conventional forms of therapy. MicroRNAs are small RNAs that had been found to regulate their targets by specific binding to the 3′-untranslated region (3′UTR) of(More)
A versatile strategy to endow biomaterials with long-term antibacterial ability without compromising the cytocompatibility is highly desirable to combat biomaterial related infection. TiO2 nanotube (NT) arrays can significantly enhance the functions of many cell types including osteoblasts thus having promising applications in orthopedics, orthodontics, as(More)
MicroRNAs (miRNAs) play vital roles in the regulation of cell cycle, cell growth, apoptosis, and tumorigenesis. Our previous studies showed that miR-526a positively regulated innate immune response by suppressing CYLD expression, however, the functional relevance of miR-526a expression and cell growth remains to be evaluated. In this study, miR-526a(More)
An antibacterial substance from Streptococcus sanguinis (S. sanguinis) is known to have an inhibitory effect on putative periodontal pathogens, but its inhibitory effect on pathogens of oral candidiasis is unknown. In this study, intracellular and exocrine proteins were extracted from S. sanguinis. The antagonistic effect of the protein extracts on(More)
Vibrational circular dichroism (VCD) of a series of proteins in H(2)O solution with differing secondary structure are reported for the first time in the near-infrared (NIR) region as well as the NH-stretching region. The Fourier transform (FT) near-infrared (NIR) measurements were carried out between 6000 to 4000 cm(-1). FT-VCD measurements were(More)
