RATIONALE DNA methylation is an important epigenetic mechanism, which often occurs in response to environmental stimuli and is crucial in regulating gene expression. It is likely that epigenetic alterations contribute to pathogenesis in idiopathic pulmonary fibrosis (IPF). OBJECTIVES To determine the DNA methylation changes in IPF and their effects on gene expression. METHODS Total DNA meth...

Hybridization plays an important evolutionary role in several groups of organisms. A phylogenetic approach to detect hybridization entails sequencing multiple loci across the genomes of a group of species of interest, reconstructing their gene trees, and taking their differences as indicators of hybridization. However, methods that follow this approach mostly ignore population effects, such as ...

We apply the dynamical large-$N$ Schwinger boson technique as an impurity solver for mean-field theory (DMFT) calculations of Kondo lattice model. Our approach captures hybridization physics through DMFT self-consistency that is missing in pure with independent electron baths. The resulting thermodynamic and transport properties are qualitative agreement more rigorous give correct crossover beh...

We have applied the method of genomic microarray to investigate amplification of oncogenes throughout the genome of nasopharyngeal carcinoma (NPC). Array based comparative genomic hybridization (array CGH) allows simultaneous examination of 58 oncogenes commonly amplified in various human cancers. In the present study, we have examined 15 NPC samples including five cell lines, two xenografts an...

Mantle cell lymphoma (MCL) is an aggressive, highly proliferative B-cell non-Hodgkin lymphoma, characterized by the specific t(11;14)(q13;q32) translocation. It is well established that this translocation alone is not sufficient to promote MCL development, but that additional genetic changes are essential for malignant transformation. We have identified such additional tumorigenic triggers in M...

Animal hybridization is well documented, but evolutionary outcomes and conservation priorities often differ for natural and anthropogenic hybrids. Among primates, an order with many endangered species, the two contexts can be hard to disentangle from one another, which carries important conservation implications. Callithrix marmosets give us a unique glimpse of genetic hybridization effects und...

The transfer of genes from crop plants to their wild relatives via hybridization has emerged as one of the primary risks associated with the commercialization of genetically engineered crops. Although previous studies have revealed relatively high levels of hybridization when crop plants come into contact with their wild relatives, the frequency of such contact across the range of cultivation o...

The effects of the direct interaction between hybridization and speciation-two major contrasting evolutionary processes--are poorly understood. We present here the evolutionary history of the Galápagos marine iguana (Amblyrhynchus cristatus) and reveal a case of incipient within--island speciation, which is paralleled by between-island hybridization. In-depth genome-wide analyses suggest that A...
