The Rac exchange factor Tiam1 is involved in diverse cell functions and signaling pathways through multiple protein interactions, raising the question of how signaling and functional specificity are achieved. We have shown that Tiam1 interactions with different scaffold proteins activate different Rac-dependent pathways by recruiting specific Rac effector(More)
The tumor microenvironment undergoes changes concurrent with neoplastic progression. Cancer incidence increases with aging and is associated with tissue accumulation of senescent cells. Senescent fibroblasts are thought to contribute to tumor development in aging tissues. We have shown that fibroblasts deficient in the Rac exchange factor Tiam1 promote(More)
BACKGROUND Bipolar disorder is a highly heritable polygenic disorder. Recent enrichment analyses suggest that there may be true risk variants for bipolar disorder in the expression quantitative trait loci (eQTL) in the brain. AIMS We sought to assess the impact of eQTL variants on bipolar disorder risk by combining data from both bipolar disorder(More)
BACKGROUND Lung cancer is the leading cause of cancer-related death and has become an enormous economic burden in China. Low-dose spiral computed tomography (LDCT) screening could reduce lung cancer mortality. The feasibility of conducting a population-based lung cancer screening with LDCT in China is uncertain. METHODS In 2010, a demonstration program of(More)
This review summarizes the use of metal-organic frameworks (MOFs) as a versatile supramolecular platform to develop heterogeneous catalysts for a variety of organic reactions, especially for liquid-phase reactions. Following a background introduction about catalytic relevance to various metal-organic materials, crystal engineering of MOFs, characterization(More)
The co-evolution of tumors and their microenvironment involves bidirectional communication between tumor cells and tumor-associated stroma. Various cell types are present in tumor-associated stroma, of which fibroblasts are the most abundant. The Rac exchange factor Tiam1 is implicated in multiple signaling pathways in epithelial tumor cells and lack of(More)
BACKGROUND AND OBJECTIVE   Lung cancer metastasis is a complicated process in which multiple stages and multiple genes are involved. There is an urgent need to use new molecular biology techniques to get more systematic information and have a general idea of the molecular events that take place in lung cancer metastasis. The object of this study was to(More)
PURPOSE To investigate the improvement and maintenance of the quality of life in the patients after phacoemulsification with intraocular lens implantation. METHODS The study population consisted of 116 patients receiving phacoemulsification with intraocular lens implantation. They were interviewed using the quality of life questionnaire, and the clinical(More)
PURPOSE To compare the outcomes of phacoemulsification with intraocular lens implantation on vision function in the first eye with that in the second eye in one week after surgery measured by the questionnaire of vision function. METHODS Forty-seven patients who underwent phacoemulsification with intraocular lens implantation in both eyes, were(More)
