OBJECTIVE 5-lipoxygenase (5-LO) is a key enzyme in the synthesis of leukotrienes (LTs), that might promote carcinogenesis. We investigated 5-LO expression and examined whether the 5-LO pathway is associated with the proliferation of human brain tumors. METHODS We immunohistochemically evaluated the profile of 5-LO expression in various types of brain(More)
To better understand the genetic bases of postmating responses in Drosophila melanogaster females, we screened a collection of P{GS} insertion lines and identified two insertions in sarah (sra), whose misexpression in the nervous system induced high levels of ovulation in virgins. The gene sra encodes a protein similar to human Down syndrome critical region(More)
Numerous studies have demonstrated that prostaglandin H synthase-2 (PHS-2) is involved in gastrointestinal carcinogenesis, and that nonsteroidal anti-inflammatory drugs (NSAIDs), which inhibit PHS, can reduce the risk of colon cancer. In brain tumors, elevated prostaglandin production and its correlation to anaplastic grade of gliomas have been(More)
