Identification of novel targets for the development of more effective antimalarial drugs and vaccines is a primary goal of the Plasmodium genome project. However, deciding which gene products are ideal drug/vaccine targets remains a difficult task. Currently, a systematic disruption of every single gene in Plasmodium is technically challenging. Hence, we(More)
MOTIVATION Biological processes can be considered at many levels of detail, ranging from atomic mechanism to general processes such as cell division, cell adhesion or cell invasion. The experimental study of protein function and gene regulation typically provides information at many levels. The representation of hierarchical process knowledge in biology is(More)
Malignant phyllodes tumors of the breast are poorly understood rare neoplasms with potential for aggressive behavior. Few efficacious treatment options exist for progressed or metastatic disease. The molecular features of malignant phyllodes tumors are poorly defined, and a deeper understanding of the genetics of these tumors may shed light on pathogenesis(More)
Large plaque-type blue nevi with subcutaneous cellular nodules are rare tumors occurring on the trunk with deep extension into underlying soft tissues. The histopathologic appearance consists of deep nodules resembling cellular blue nevi with interspersed foci of common blue nevus. Conservative management has been recommended, and metastases have not been(More)
Spitzoid neoplasms are a group of melanocytic tumours with distinctive histopathological features. They include benign tumours (Spitz naevi), malignant tumours (spitzoid melanomas) and tumours with borderline histopathological features and uncertain clinical outcome (atypical Spitz tumours). Their genetic underpinnings are poorly understood, and alterations(More)
We report four cases of diffuse infantile hepatic hemangioma, a rare but potentially life-threatening subset of hepatic hemangiomas. All patients demonstrated distinctive dome-shaped red-purple cutaneous hemangiomas. Two patients responded to steroids and propranolol (one in combination with vincristine), and two responded to steroids and vincristine. After(More)
At our body surface, the epidermis absorbs UV radiation. UV overexposure leads to sunburn with tissue injury and pain. To understand how, we focus on TRPV4, a nonselective cation channel highly expressed in epithelial skin cells and known to function in sensory transduction, a property shared with other transient receptor potential channels. We show that(More)
MOTIVATION A critical element of the computational infrastructure required for functional genomics is a shared language for communicating biological data and knowledge. The Gene Ontology (GO; http://www.geneontology.org) provides a taxonomy of concepts and their attributes for annotating gene products. As GO increases in size, its ongoing construction and(More)
