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)
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)
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)
Resistance to antiestrogens is one of the major challenges in breast cancer treatment. Although phosphorylation of estrogen receptor α (ERα) is an important factor in endocrine resistance, the contributions of specific kinases in endocrine resistance are still not fully understood. Here, we report that an important innate immune response kinase, the IκB(More)
High mobility group box 1 (HMGB1) is a ubiquitous nuclear DNA-binding protein whose function is dependent on its cellular location. Extracellular HMGB1 is regarded as a delayed mediator of proinflammatory cytokines for initiating and amplifying inflammatory responses, whereas nuclear HMGB1 has been found to prevent cardiac hypertrophy and heart failure.(More)
