Two (or more) bacterial promoters are often found in close proximity, and may compete for the binding of RNA polymerase. These competing promoters have interesting characteristics in vitro and analysis of the competition should be valuable to kinetic studies of more complex transcription systems.

B-box proteins (BBX) play pivotal roles in the regulation of numerous growth and developmental processes in plants, particularly the light-mediated biosynthesis of pigments. To elucidate the role of BBX transcription factors in the anthocyanin biosynthetic pathway of Lagerstroemia indica leaves, this study identified 41 BBX genes in the L. indica genome.

The dysfunction of the endothelial lining in lesion-prone areas of the arterial vasculature significantly contributes to the pathobiology of atherosclerotic cardiovascular disease. Recent studies suggested that UDP-glucose pyrophosphorylase 2 (UGP2) plays a role in cell proliferation and survival. This study investigates the anti-apoptotic and anti-atherogenic effects of UGP2 both in vitro and in vivo.

Background: Aspergillus niger is an important industrial filamentous fungus used to produce organic acids and enzymes. A wide dynamic range of promoters, particularly strong promoters, are required for fine-tuning the regulation of gene expression to balance metabolic flux and achieve the high yields of desired products. However, the limited understanding of promoter architectures and activities restricts the efficient transcription regulation of targets in strain engineering in A.

Background: DNA methylation plays a crucial role in mammalian development. While methylome changes acquired in the parental genomes are believed to be erased by epigenetic reprogramming, accumulating evidence suggests that methylome changes in sperm caused by environmental factors are involved in the disease phenotypes of the offspring. These findings imply that acquired sperm methylome changes are transferred to the embryo after epigenetic reprogramming.
