TASK: the task is to classify relations between a chemical and a gene for a sentence. 

INPUT: the input is a sentence where the chemical is labeled as @CHEMICAL$ and the gene is labeled as @GENE$ accordingly in a sentence. 

OUTPUT: your task is to select one out of the six types of relations ('CPR:3', 'CPR:4', 'CPR:5', 'CPR:6', 'CPR:9', and 'false') for the gene and chemical without any explanation or other characters:

CPR:3, which includes UPREGULATOR, ACTIVATOR, and INDIRECT UPREGULATOR

CPR:4, which includes DOWNREGULATOR, INHIBITOR ,and INDIRECT DOWNREGULATOR

CPR:5, which includes AGONIST, AGONIST ACTIVATOR, and AGONIST INHIBITOR

CPR:6, which includes ANTAGONIST

CPR:9, which includes SUBSTRATE, PRODUCT OF and SUBSTRATE PRODUCT OF

false, which indicates no relations

The following examples are provided:

Example-1 Q: Three lines of evidence suggest that calmodulin inhibition is not responsible for the inhibition of binding and endocytosis: 1) Promethazine, a phenothiazine that is a poor inhibitor of calmodulin, is nearly as effective as TFP at inhibiting endocytosis; calmidazolium, a potent inhibitor of several calmodulin functions, did not cause a loss of binding; 2) the microinjection of calmodulin into cells did not reverse the effects of @CHEMICAL$; using pressure microinjection, we introduced up to a 100-fold excess of @GENE$ over native levels into individual gerbil fibroma cells; using rhodamine-labeled alpha 2-macroglobulin, we saw that the W-7 induced inhibition of receptor-mediated endocytosis was the same in injected and uninjected cells; 3) we injected calcineurin, a calmodulin-binding protein, into cells (1-3 pg/cell) and observed no effect on the receptor-mediated endocytosis of rhodamine-labeled alpha 2-macroglobulin.

Example-1 A: false

Q: In rat plasma the BrBK half-life values in the absence or in the presence of GW660511X (530 nM) or omapatrilat (50 nM) were 9.31 +/- 1.7, 22.06 +/- 3.1 and 25.3 +/- 1.7 min, respectively and BrBK was degraded into @CHEMICAL$, BrBK1-7, BrBK1-5 and Br-Phe5 plus @GENE$, BrBK4-8 and BrBK2-8 metabolites not found in human plasma. GW660511X and omapatrilat reduced the production of BrBK1-5 and BrBK1-7 with more effect being observed with omapatrilat. GW660511X and omapatrilat increased the production of both BrBK1-8 and Br-Phe5 but not that of BrBK4-8 and BrBK2-8.
