The BAP1 tumor suppressor is mutated in many human cancers such as uveal melanoma, leading to poor patient outcome. It remains unclear how BAP1 functions in normal biology or how its loss promotes cancer progression. Here, we show that Bap1 is critical for commitment to ectoderm, mesoderm, and neural crest lineages during Xenopus laevis development...
Conference Paper
Uveal melanoma (UM) is the second most common form of melanoma and one of the most deadly types of cancer. Recent discoveries in our laboratory and others have led to a deeper understanding of the driver mutations UM. The initiating mutation that is present in virtually all UM occurs in one of four genes in the Gaq signaling pathway (the “Gaq” muta...

During oogenesis, hundreds of maternal RNAs are selectively localized to the animal or vegetal pole, including determinants of somatic and germline fates. Although microarray analysis has identified localized determinants, it is not comprehensive and is limited to known transcripts. Here, we utilized high-throughput RNA-sequencing analysis to compr...

Neural crest formation is one of the fundamental processes in the early stages of embryonic development in vertebrates. This transient and multipotent embryonic cell population is able to generate a variety of tissues and cell types in the adult body. hairy genes are transcription factors that contain a bHLH domain which binds to DNA. In Xenopus th...

Background: The neural crest is a transient multipotent migratory cell population unique to vertebrates. These cells undergo an epithelial-to-mesenchymal transition and migrate extensively through the embryo. They differentiate into numerous diverse derivatives including the peripheral nervous system, melanocytes,and craniofacial cartilages. The d...

It has been established in several models that the p63 gene has an important role in the development of the epidermis and its derivatives. In Xenopus, only the ΔNp63 isoform of this gene has been cloned and its role during epidermal development remains unknown. In this work, we showed that ΔNp63 is expressed in the nonneural ectoderm since the gast...

Neural crest induction is the result of the combined action at the neural plate border of FGF, BMP, and Wnt signals from the neural plate, mesoderm and nonneural ectoderm. In this work we show that the expression of Indian hedgehog (Ihh, formerly named Banded hedgehog) and members of the Hedgehog pathway occurs at the prospective neural fold, in th...

Cellular nucleic-acid-binding protein (CNBP) plays an essential role in forebrain and craniofacial development by controlling cell proliferation and survival to mediate neural crest expansion. CNBP binds to single-stranded nucleic acids and displays nucleic acid chaperone activity in vitro. The CNBP family shows a conserved modular organization of...
