Packet 7: Tossup 8

According to the Knudson hypothesis, genes named for countering these structures require “two hits” to deactivate. (15[2])During inflammation, macrophages (15[1])secrete a cytokine (“SIGH-toh-kyne”) known as these structures’ namesake “necrosis factor.” These structures, (15[1])whose namesake suppressor genes include the “guardian (15[1])angel (15[1])of the (15[1])genome” (*) p53 (10[2])(“P-fifty-three”), are also known (-5[2])as neoplasms. The first immortal human cell line, HeLa (10[1])(“hee-lah”) cells, were extracted from (10[1])one of these structures (10[2])in the cervix. These structures (10[2])can be (10[1])benign or (10[1])malignant (10[3])depending (10[2])on (10[1])if they spread (10[1])or not, (10[1])a process known as metastasis. For 10 points, name these abnormal cell growths that may be cancerous. ■END■ (10[1])
