TASK DEFINITION: In this task, you are given a sentence. You are expected to recognize the name of gene or protein. Although there might be several correct answers, you need to write one of them.
PROBLEM:  Both lines have epithelial morphology , form tumors slowly in nude mice [ 37 ] , have mutant p53 [ 39 , 40 ] , express EGFR [ 37 ] , and lack estrogen receptor alpha [ 41 ] .

SOLUTION: nude mice

PROBLEM:  Previous studies with B . mallei and the host response have shown that a mixed immune response consisting of both Th1 and Th2 - associated cytokines with a predominant IgG1 subclass does not correlate with protection [ 4 ] .

SOLUTION: B . mallei

PROBLEM:  Thus , loss or reduction of TNF - alpha and IFN - gamma levels result in significantly reduced survival rates , substantiating previous reports of the role of these factors in protection against B . mallei [ 7 ] .

SOLUTION:
B . mallei
