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.

Example Input:  In K562 cells , using the bicistronic vector , selection with colchicine led to at least 20 - fold higher expression of the MDR1 gene product than did selection with G418 , suggesting that the stringent MDR1 selection system is very efficient for obtaining overexpression of foreign genes .
Example Output: MDR1 gene product

Example Input:  Nitroglycerin ( glyceryl trinitrate ) as a monoamine oxidase inhibitor .
Example Output: monoamine oxidase

Example Input:  At promoters that initiate with + 1 GGG , T7 RNAP synthesizes a ladder of poly ( G ) products as a result of slippage of the transcript on the three C residues in the template strand from + 1 to + 3 .
Example Output:
T7 RNAP
