Profiles of PTK genes expressed in human gastric cancer tissues. Expression of each PTK gene is indicated by the frequency of clones identified. In the top panel (patient 1), 110 clones from a gastric cancer tissue and 50 clones from its matching normal gastric mucosa tissue were sequenced. A total of 32 different PTK genes were identified and grouped by nonreceptor PTK, receptor PTK, dual and other kinases, and new kinases. In the bottom panel (patient 2), 160 clones from gastric tumor tissues and 98 clones from its normal mucosa tissues were sequenced. A total of 34 PTK genes were identified.
