Carcinoma

... of hepatocellular carcinoma granted in March 2000. Approved in several overseas markets; investigational in the U.S. To identify tumor suppressor loci, we have completed an allelic deletion map of small cell lung carcinoma s, and are commencing on a similar map for non-sm~ cell lung ...

Chromosome

... commonly deleted in prostate cancer ; consequently, many groups have focused on using deletion mapping in an attempt to localize one or more tumor suppressor genes in this region. A gene on chromosome 17 that normally helps to suppress cell growth. A person who inherits an altered version of the ...

Chromosomes

... Scientists have found links between the disease and certain chromosomes , including chromosomes 10, 14, 19, and 21. Additional tumor suppressor or tumor -progressive genes may lie on chromosomes 16q and 1p as evidenced by LOH for these regions in 17% and 11% of Wilms' tumor s, respect ...
