Fibroblasts can be reprogrammed to induced pluripotent stem cells (iPSCs) by application of transcription factors octamer-binding protein 4 (Oct4), SRY-box containing gene 2 (Sox2), Kruppel-like factor 4 (Klf4), and c-Myelocytomatosis oncogene (c-Myc) (OSKM), but the underlying mechanisms remain unclear. Here, we report that exogenous Oct4 and Sox2 can bind(More)
Hypermethylation of CpG islands is well known as a major inactivation mechanism of tumor suppressor genes. E-cadherin (E-cad) as a tumor invasion suppressor has been reported in several invasive and metastatic carcinomas. However, its significance in carcinogenesis of primary non-small cell lung cancer (NSCLC) is not well documented. This study was designed(More)
BACKGROUND The -160C/A polymorphism (rs16260) of E-cadherin, a tumor repressor gene, has been shown to be a tumor susceptibility allele for various types of cancers. Because the significance of this polymorphism to cancer risk has been recognized, there are increasing studies investigating -160C/A in different types of cancers and ethnic populations.(More)
Expression divergence of duplicate genes is widely believed to be important for their retention and evolution of new function, although the mechanism that determines their expression divergence remains unclear. We use a genetical genomics approach to explore divergence in genetical control of yeast duplicate genes created by a whole-genome duplication that(More)
Recently, the debate on the centrality-lethality rule is resolved by the "second-generation" high-throughput Y2H data from the yeast interactome network, which suggests no significant correlation between the degree of connectedness and essentiality of proteins. However, it is still not clear why essential proteins strongly tend to interact with each other.(More)
Angiogenesis is crucially involved in many physiological and pathological processes including tumor growth, but the molecular mechanisms regulating angiogenesis are incompletely understood. In this study, we investigated the functions and mechanism of histone deacetylase 10 (HDAC10), a member of the HDAC II family, in regulation of angiogenesis. HDAC10(More)
Cell aggregation in unicellular organisms, induced by either cell non-sexual adhesion to yield flocs and biofilm, or pheromone-driving sexual conjugation is of great significance in cellular stress response, medicine, and brewing industries. Most current literatures have focused on one form of cell aggregation termed flocculation and its major molecular(More)
NADPH oxidase 4 (NOX4) is a member of the NADPH oxidase (NOX) family of enzymes and has been found abnormally expressed in human cancers. However, its role in gastric cancer (GC) is still unclear. In the current study, we reported that NOX4 expression levels were significantly up-regulated in GC tissues compared to normal tissues (P<0.0001). Higher NOX4(More)
Clarifying the regulatory mechanisms of embryonic stem cell (ESC) neural differentiation is helpful not only for understanding neural development but also for obtaining high-quality neural progenitor cells required by stem cell therapy of neurodegenerative diseases. Here, we found that long noncoding RNA 1604 (lncRNA-1604) was highly expressed in cytoplasm(More)
