A geometric approach to scalar field theories on the supersphere
Following a strictly geometric approach we construct globally supersymmetric scalar field theories on the supersphere, defined as the quotient space $S^{2|2} = UOSp(1|2)/\mathcal{U}(1)$.

The metabolism of melanin synthesis—From melanocytes to melanoma
Melanin synthesis requires coordinated metabolism across the subcellular compartments within melanocytes. In this review, the metabolism of melanin synthesis is discussed in detail with special emphasis placed on the potential intersection with melanoma tumor biology. Abstract Melanin synthesis involves the successful coordination of metabolic pathways

The MatP/matS Site-Specific System Organizes the Terminus Region of the E. coli Chromosome into a Macrodomain [PDF]
The organization of the Escherichia coli chromosome into insulated macrodomains influences the segregation of sister chromatids and the mobility of chromosomal DNA. Here, we report that organization of the Terminus region (Ter) into a macrodomain relies on the presence of a 13 bp motif called matS repeated 23 times in the 800-kb-long domain. matS sites

We explored how genetic variability of black spruce populations, shaped by their postglacial history and adaptation to local climate, affects the species' response to future climate change (CC). By analyzing tree rings and genetic data from 62 populations planted in four common gardens across Canada, we found that populations with varied postglacial ...

Gene expression in Sinclair swine with malignant melanoma
Sinclair swine develop an aggressive form of melanoma, which, in many cases, spontaneously regresses after a complete metastatic phase. We used Affymetrix GeneChip® Porcine Genome Arrays consisting of 24 123 probe sets to compare gene expression in white

Gene silencing and large-scale domain structure of the E. coli genome
The H-NS chromosome-organizing protein in E. coli can stabilize genomic DNA loops, and form oligomeric structures connected to repression of gene expression.

Abstract Enzymes are nature's catalysts, mediating chemical processes in living systems. The study of enzyme function and mechanism includes defining the maximum catalytic rate and affinity for substrate/s (among other factors), referred to as enzyme kinetics.

We conducted a multi-stage genome-wide association study of natural hair color in more than 10,000 men and women of European ancestry from the United States and Australia. An initial analysis of 528,173 single nucleotide polymorphisms (SNPs) genotyped on

The Escherichia coli CrfC protein is an important regulator of nucleoid positioning and equipartition. Previously we revealed that CrfC homo-oligomers bind the clamp, a DNA-binding subunit of the DNA polymerase III holoenzyme, promoting colocalization of
