(cont) An increased understanding of heterotrophic bacterial strategies for acquiring nutrients and trace elements is critical for elucidating their impact on biogeochemical cycling in the ocean. It is estimated that iron ...

As mammals age, osteoblast numbers decrease while osteoclast numbers increase, resulting in age-related or post-menopausal osteoporosis. SirT1, the mammalian orthologue of yeast Sir2, has been shown to be a negative regulator ...

Sox2 is a master regulator of two distinct cellular states, that of pluripotent embryonic stem cells (ESCs) and multipotent neural progenitor cells (NPCs), but what common or distinct roles Sox2 may play in these cell types ...

Ecological processes at deep-sea hydrothermal vents on fast-spreading mid-ocean ridges are punctuated by frequent physical disturbance. Larval dispersal among disjunct vent sites facilitates the persistence of sessile ...

Larval supply is an important process linking reproductive output to recruitment of benthic marine invertebrates. Few species-specific studies of bivalve larvae have been performed due to the lack of suitable methods for ...

Energy dependent proteolysis is a critical method of cellular regulation for all forms of life. The AAA+ proteases ClpXP and ClpAP in E. coli function in this capacity by facilitating the denaturation and degradation of ...

(cont.) DNA damage response, we hypothesize that the perinuclear pool of Mad proteins may be required for spindle checkpoint-independent functions such as invoking metaphase arrest following DNA damage.
