Pitch Lake in Trinidad and Tobago is a natural asphalt reservoir nourished by pitch seepage, a form of petroleum that consists of mostly asphaltines, from the surrounding oil-rich region. During upward seepage, pitch mixes with mud and gases under high pressure, and the lighter portion evaporates or is volatilized, which produces a liquid asphalt residue(More)
The vast majority of microbes in nature currently remain inaccessible to traditional cultivation methods. Over the past decade, culture-independent environmental genomic (i.e. metagenomic) approaches have emerged, enabling researchers to bridge this cultivation gap by capturing the genetic content of indigenous microbial communities directly from the(More)
Gene amplifications in the 17q chromosomal region are observed frequently in breast cancers. An integrative bioinformatics analysis of this region nominated the MAP3K3 gene as a potential therapeutic target in breast cancer. This gene encodes mitogen-activated protein kinase kinase kinase 3 (MAP3K3/MEKK3), which has not yet been reported to be associated(More)
Testicular germ-cell tumors (TGCTs) show exquisite sensitivity to cisplatin-based chemotherapy, and therefore this is considered a good model system for studying the mechanism of chemotherapy resistance. Although the genetic alterations related to TGCT have been well studied, little is known about the genetic basis of chemotherapy resistance, which occurs(More)
The genotype of a tumor determines its biology and clinical behavior. The genetic alterations associated with the unique embryonal morphology of nonseminomatous subtypes of testicular germ cell tumors remain to be established. Using single nucleotide polymorphism microarray analysis, we found in all of the 15 nonseminomas analyzed, large-scale chromosomal(More)
An understanding of the role of methane hydrates in the global carbon cycle, and in past and future climate change, is dependent on an understanding of methane consumption in hydrate-associated environments. In the marine environment, a dual-component microbial biofilter consumes up to 80% of methane produced. Throughout most of the world's ocean the(More)
