E2F transcription factors were originally identified as regulators of cell cycle and cellular proliferation. In vivo mouse models have uncovered novel roles for these proteins in different developmental processes. This ...

In this thesis, I provide quantitative descriptions of toothed whale echolocation and foraging behavior, including assessment of the effects of noise on foraging behavior and the potential influence of ocean acoustic ...

Marine thecate heterotrophic dinoflagellates likely play an important role in the consumption of primary productivity and in the trophic structure of the plankton, yet we know little about these species. This thesis expanded ...

Activating mutations in RAS oncogenes commonly arise in human cancers. However, in experimental settings, oncogenic RAS has most often been studied at supraphysiological levels of expression. Importantly, work by others ...

Caspases play an important role in apoptosis, or programmed cell death. In particular, three highly related effector caspases, caspases-3, -6, and -7, translate upstream death signals into the physical manifestations of ...

Nanobiotechnology aims to exploit biomolecular recognition and self-assembly capabilities for integrating advanced materials into medicine and electronics. In particular, peptides have exhibited the ability to specifically ...

(cont.) The vertebrate-specific miR-196 family is encoded at three paralogous loci in the mammalian Hox clusters, and has complementarity to messages of several Hox genes, including Hox8 paralogues. RNA fragments diagnostic ...

Meiosis is the cell division by which gametes are produced. Meiotic chromosome segregation differs from Mitotic segregation in that one DNA replication phase is followed by two chromosome segregation phases. This allows ...
