TRPM2, a member of the transient receptor potential (TRP) superfamily, is a Ca(2+)-permeable channel activated by oxidative stress or tumor necrosis factoralpha involved in susceptibility to cell death. TRPM2 activation is dependent on the level of intracellular Ca(2+). We explored whether calmodulin (CaM) is the Ca(2+) sensor for TRPM2. HEK 293T cells were(More)
The cannabinoid receptor 2 (CB2) plays an important role in the immune system. Although a few of GPCRs crystallographic structures have been reported, it is still challenging to obtain functional transmembrane proteins and high resolution X-ray crystal structures, such as for the CB2 receptor. In the present work, we used 10 reported crystal structures of(More)
Transient receptor potential vanilloid type 1 (TRPV1), a heat-sensitive calcium channel protein, contributes to inflammation as well as to acute and persistent pain. Since TRPV1 occupies a central position in pathways of neuronal inflammatory signaling, it represents a highly attractive potential therapeutic target for neuroinflammation. In the present(More)
OBJECTIVE The objectives of this study were to describe the distribution of brain metastases (BM) in breast cancer patients and investigate the risk factors for perihippocampal metastases (PHM). PATIENTS AND METHODS Retrospective analysis of the clinicopathological characteristics and patterns of BM was performed. Associations between clinicopathological(More)
Cannabinoid receptor 2 (CB2), a G protein-coupled receptor (GPCR), is a promising target for the treatment of neuropathic pain, osteoporosis, immune system, cancer, and drug abuse. The lack of an experimental three-dimensional CB2 structure has hindered not only the development of studies of conformational differences between the inactive and active CB2 but(More)
Hematopoietic stem cells (HSCs) have emerged as promising therapeutic cell sources for high-risk hematological malignancies and immune disorders. However, their clinical use is limited by the inability to expand these cells ex vivo. Therefore, there is an urgent need to identify specific targets and effective probes that can expand HSCs. Here we report a(More)
Bovine viral diarrhea virus (BVDV) is one of the most important pathogens in cattle. Previously, BVDV sub-genotypes of 1b, 1c, 1d, and 1 m were detected in China. However, isolation of BVDV type 1a from cattle has not been reported in China. In 2010, twenty nasal swabs and blood samples were collected from the cattle suspected BVDV infection in Henan(More)
Porcine reproductive and respiratory syndrome virus (PRRSV) could infect porcine alveolar macrophages (PAM), and the CD169 and CD163 are identified as critical receptors on the surface of PAM, but whether the single nucleotide polymorphisms (SNPs) of these genes could influence the infection is remain unclear. In this study, we identified totally 6 SNPs for(More)
