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: After 12 months of treatment, @CHEMICAL$ significantly improved all end points (plasma concentration of B-type natriuretic peptide [@GENE$] from 175 (35 to 209) to 106 (52 to 160) pg/ml, mean (95% confidence interval) p <0.01; New York Heart Association functional class from 2.37 (2.13 to 2.61) to 1.56 (1.21 to 1.91), p <0.01; exercise capacity estimated with the Specific Activity Scale from 4.75 (4.50 to 5.00) to 5.68 (5.22 to 6.14) METs, p <0.02), whereas conventional therapy did not (plasma BNP concentration from 150 (114 to 186) to 174 (100 to 248) pg/ml; New York Heart Association functional class from 2.29 (2.08 to 2.50) to 2.11 (1.73 to 2.49); exercise capacity from 4.57 (4.34 to 4.80) to 4.72 (4.41 to 5.03) METs).
