In mammalian cells, the main pathway for DNA double-strand breaks (DSBs) repair is classical non-homologous end joining (C-NHEJ). An alternative or back-up NHEJ (B-NHEJ) pathway has emerged which operates preferentially under C-NHEJ defective conditions. Although B-NHEJ appears particularly relevant to genomic instability associated with cancer, its(More)
PURPOSE We aimed to investigate the effects of adiponectin on liver cancer growth and metastasis and explore the underlying mechanisms. EXPERIMENTAL DESIGN An orthotopic liver tumor nude mice model with distant metastatic potential was applied. Either Ad-adiponectin (1 x 10(8); treatment group) or Ad-luciferase (control group) was injected via portal vein(More)
Interleukin (IL)-17A is expressed in the tumor microenvironment where it appears to contribute to tumor development, but its precise role in tumor immunity remains controversial. Here, we report mouse genetic evidence that IL-17A is critical for tumor growth. IL-17A-deficient mice exhibited reduced tumor growth, whereas systemic administration of(More)
UNLABELLED The ubiquitous serine/threonine kinase glycogen synthase kinase 3 beta (Gsk3β) differentially regulates macrophage Toll-like receptor (TLR)-triggered pro- and anti-inflammatory cytokine programs. This study was designed to determine the in vivo role and therapeutic potential of Gsk3β modulation in tissue inflammation and injury in a murine model(More)
BACKGROUND Hepatocellular carcinoma (HCC) is highly malignant and metastatic. Currently, there is no effective chemotherapy for patients with advanced HCC leading to an urgent need to seek for novel therapeutic options. We aimed to investigate the effect of a garlic derivative, S-allylcysteine (SAC), on the proliferation and metastasis of HCC. (More)
BACKGROUND Although endoplasmic reticulum (ER) stress has been implicated in the pathophysiology of organ ischemia-reperfusion injury (IRI), the underlying mechanisms have yet to be fully elucidated. In particular, because tissue proinflammatory immune response is the key mediator of local IRI, how ER stress impacts liver immune cell activation cascade(More)
OBJECTIVE We aimed to explore the precise molecular mechanism of early and invasive tumor growth in a small-for-size graft after liver transplantation and to identify the distinct molecular signature linked to acute-phase injury and late-phase tumor invasiveness. SUMMARY BACKGROUND DATA Acute phase small-for-size liver graft injury plays an important role(More)
The mammalian intestinal microbiota is a complex ecosystem that plays an important role in host immune responses. Recent studies have demonstrated that alterations in intestinal microbiota composition are linked to multiple inflammatory diseases in humans, including acute graft-versus-host disease (aGVHD). aGVHD is one of the major obstacles in allogeneic(More)
Adenosine deaminase acting on RNA 1 (ADAR1) catalyzes RNA editing of cellular and viral RNAs. Besides RNA editing, ADAR1 has recently been shown to play important roles in maintaining the body balance, including tissue homoeostasis, organ development, and autoimmune regulations, by inhibiting both IFN production and subsequent IFN-activated pathways.(More)
OBJECTIVE Hypoxic tumor cells are more resistant to standard chemotherapies. A number of studies indicated that improving oxygenation inside the tumor could serve as a potential strategy to target hypoxia-induced chemoresistance. In this study, we examined whether a hemoglobin-based oxygen carrier (OC89) could increase tumor oxygenation and thus enhance the(More)
