Metastasis-associated in colon cancer-1 (MACC1) is a newly identified oncogene, and little is known about its role in gastric cancer (GC). Our study was performed to investigate whether MACC1 influences the prognosis of GC patients and to explore the potential mechanisms involved. MACC1 expression was verified to be higher in GC tissues than in adjacent(More)
AIM To evaluate the protective effect of live attenuated Salmonella typhimurium expressing catalase against gastric Helicobacter pylori infection in mice, and to explore the underlying mechanisms of the protective immune reaction. MATERIALS AND METHODS The H. pylori catalase gene was introduced into attenuated S. typhimurium strain SL3261. C57BL/6 mice(More)
There is evidence that drug-specific T cells are involved in inducing keratinocyte apoptosis in acute stage of Steven-Johson syndrome (SJS) and Toxic epidermal necrolysis (TEN). However, there are few studies that have attempted to examine T cell memory responses over time. We sought to determine the duration of IFN-γ and sFasL memory response to causal(More)
Photodynamic therapy is a potentially advantageous treatment for non-melanoma skin cancers. We evaluated the clinical response, recurrence and adverse events of photodynamic therapy for in situ extramammary Paget's disease in 14 male and 3 female Chinese patients with 21 lesions. Topical 20% 5-aminolevulinic acid was applied for 6 h. Each lesion was(More)
Microtubule-associated protein light chain 3 (LC3A) is a reliable marker of autophagy that displays three distinct patterns of immunohistochemical staining in solid tumors: diffuse cytoplasmic staining, juxtanuclear staining, and staining of "stone-like" structures. These three patterns have a different prognostic significance in many solid tumors, but(More)
The use of photoacoustic effect is a promising approach for biomedical imaging in living tissues. Photoacoustic tomography (PAT) has been demonstrated to image breast cancer, brain vasculature, arthritis and seizure focus owing to its rich optical contrast and high resolution in a single imaging modality. Here we report a microelectromechanical systems(More)
XB130 has been reported to be expressed by various types of cells such as thyroid cancer and esophageal cancer cells, and it promotes the proliferation and invasion of thyroid cancer cells. Our previous study demonstrated that XB130 is also expressed in gastric cancer (GC), and that its expression is associated with the prognosis, but the role of XB130 in(More)
Keratinocytes (KCs) play a critical role in maintaining the cutaneous structure and are involved in various physiological and pathologic processes of the skin. Many inflammatory skin diseases and skin cancers result from excessive proliferation and insufficient apoptosis of KCs. Recent data suggested that the sonic hedgehog (Shh) signalling pathway plays an(More)
Interleukin 1β (IL-1β) is a pleiotropic pro-inflammatory cytokine that plays a critical role in the development of osteoarthritis (OA). Coptisine is an isoquinoline alkaloid extracted from Coptidis rhizome and has been reported to possess anti-inflammatory activity. However, the anti-inflammatory effects of coptisine on interleukin-1 beta (IL-1β)-stimulated(More)
BACKGROUND Programmed death-1 ligand-1 (PD-L1, CD274, B7-H1) has been identified as the ligand for the immunoinhibitory receptor programmed death-1 and has been demonstrated to play a role in the regulation of immune responses and peripheral tolerance. In this study, we tested the effect of PD-L1-transfected pancreatic beta-cell line established from a(More)
