Pumilio-mediated Repression of mRNAs in the Early Drosophila Melanogaster Embryo

Nomie, Krystle Joli (2009)

Post-transcriptional regulation plays an important role in governing various processes in all organisms. The development of the early embryo of <italic>Drosophila melanogaster</italic> is governed solely by ...
Regulation of Adaptive Immunity in the Lung by the Alveolar Epithelial Type II Cell and Surfactant Protein a

Lo, Bernice (2008-08-04)

Due to its nature and function, the lungs are confronted with the unique challenge of rapidly eliminating inhaled pathogens and particulates while limiting inflammatory responses. A disruption in this immune homeostasis ...
Regulation of Asymmetric Cell Divisions in the Developing Epidermis

Poulson, Nicholas (2012)

During development, oriented cell divisions are crucial for correctly organizing and shaping a tissue. Mitotic spindle orientation can be coupled with cell fate decisions to provide cellular diversity through asymmetric ...
Regulation of Progenitor Cell Proliferation During Zebrafish Fin Regeneration

Lee, Yoonsung (2009)

Vertebrates like urodele and teleost have an enhanced capacity for regeneration, when compared to mammals. Recently, the teleost zebrafish (Danio rerio) has become a popular model for studying regenerative events, due ...
Requirements for Regenerative Mechanisms in Tissue Growth and Homeostasis in Adult Zebrafish

Wills, Airon Alease (2009)

The teleost zebrafish (danio rerio) has a highly elevated regenerative capacity compared to mammals, with the ability to quickly and correctly regenerate complex organs such as the fin and the heart following amputation. ...
The Role of Caveolin-1 and Surfactant Protein A as Regulators of Airway Hyperreactivity and Inflammation Following Innate Immune Challenges

Hsia, Bethany Joy (2011)

The lung is a unique organ, taking a key part physiology but also playing a vital role in host defense. The lung has therefore developed a complex innate immune system that includes ciliated mucus producing cells that ...
The Role of Sonic Hedgehog in Outflow Tract Development

Dyer, Laura Ann (2009)

The two major contributing populations to the outflow tract of the heart are the secondary heart field and the cardiac neural crest. These two populations are responsible for providing the myocardium that supports the ...
SR proteins in microRNA/mRNA biogenesis

Wu, Han (2011)

SR proteins are a family of splicing factors involved in the regulation of both constitutive and alternative splicing of pre-mRNAs. Despite years of studies, several big questions still remain: how the expression levels ...
Understanding Cell Fate Decisions in the Embryonic Gonad

Jameson, Samantha Ann (2011)

The divergence of distinct cell populations from multipotent progenitors is poorly understood, particularly <italic>in vivo</italic>. The gonad is an ideal place to study this process because it originates as a bipotential ...
Vascular Influence During Patterning and Differentiation of the Gonad

Cool, Jonah (2011)

The gonad is a unique primordial organ that retains the ability to adopt one of two morphological fates through much of mammalian embryonic development. Previous work in our lab found that dimorphic vascular remodeling ...
