Probable eye cancer gene scrutinized.Probable eye cancer gene scrutinized At the University of California The University of California has a combined student body of more than 191,000 students, over 1,340,000 living alumni, and a combined systemwide and campus endowment of just over $7.3 billion (8th largest in the United States). at San Diego San Diego (săn dēā`gō), city (1990 pop. 1,110,549), seat of San Diego co., S Calif., on San Diego Bay; inc. 1850. San Diego includes the unincorporated communities of La Jolla and Spring Valley. Coronado is across the bay. in La Jolla La Jolla (lə hoi`yə), on the Pacific Ocean, S Calif., an uninc. district within the confines of San Diego; founded 1869. The beautiful ocean beaches, in particular La Jolla shores and Black's Beach, and sea-washed caves attract visitors and ,researchers have cloned and characterized the gene thought responsible for susceptibility to hereditary retinoblastoma Retinoblastoma Definition Retinoblastoma is a malignant tumor of the retina that occurs predominantly in young children. Description The eye has three layers, the sclera, the choroid, and the retina. , an eye cancer found in children (SN: 1/5/85, p.10). Altered genetic material--apparently due to deletions in the gene located on chromosome 13--was detected in cells taken from retinoblastomas and two other types of tumors, according to an article in the March 13 SCIENCE. The authors say their results offer "a framework for further study of . . . genetic mechanisms in human cancers.' |
