  • An emerging role for the exocyst : plant morphogenesis

    Creator:
    Cole, Rex A.
    Abstract:
    Plants develop a vast array of cell shapes and sizes by selectively modifying their surrounding cell walls to expand in some regions and not in others. This process of morphogenesis requires the delivery of secretory vesicles to specific locations at the cell periphery, where exocytosis adds new membrane and proteins...

  • Investigating the ecological role of cell signaling in free-living marine heterotrophic protists

    Creator:
    Hartz, Aaron J.
    Abstract:
    Phagotrophic protists are major consumers of microbial biomass in aquatic ecosystems. However, biochemical mechanisms underlying prey recognition and phagocytosis by protists are not well understood. We investigated the potential roles of cell signaling mechanisms in chemosensory response to prey, and in capture of prey cells, by a marine ciliate (Uronema...

  • Role of Transcriptional Factor COUP-TF-interacting Proteins in Skin Permeability Barrier Development, and in Skin Carcinogenesis, and Role of Lipids in Atopic Dermatitis

    Creator:
    Li, Shan
    Abstract:
    Mammalian skin is the largest organ of the body and serves as a barrier to protect the body against chemical, mechanical and pathogenic insults as well as water loss. The epidermis is formed from the primitive ectoderm into a multilayered stratified epithelium, consisting of basal, spinous, granular and outermost cornified...

  • Transcriptional repression by CTIP2, a C2H2 zinc finger protein

    Creator:
    Topark-Ngarm, Acharawan Khamsiritrakul
    Abstract:
    CTIP2, a novel C2H2 zinc finger protein, is a transcriptional repressor that functions by at least two mechanisms. CTIP2 interacts with and stimulates transcriptional repression mediated by COUP-TF family members. CTIP2 also represses transcription independently of COUP-TF proteins by direct, sequence-specific DNA binding activity. CTIP2 has been implicated in lymphoid...
