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 vivo, cromolyn inhibited tumor growth in mice bearing tumor with endogenous @CHEMICAL$ (BxPC-3: control, mean = 1.6 x 10(9) photons/s, versus cromolyn, mean = 4.4 x 10(8) photons/s, difference = 1.2 x 10(9) photons/s; 95% CI = 6.2 x 10(8) to 1.6 x 10(9) photons/s; P<.001, n = 5; MPanc-96: control, mean = 1.1 x 10(10) photons/s, versus cromolyn, mean = 4.8 x 10(9) photons/s, difference = 6.2 x 10(9) photons/s; 95% CI = 1.9 x 10(9) to 1.0 x 10(10) photons/s; P = .009, n = 5) and increased the effectiveness of @GENE$ (BxPC-3: gemcitabine, mean = 9.2 x 10(8) photons/s, versus combination, mean = 1.8 x 10(8) photons/s, difference = 7.4 x 10(8) photons/s; 95% CI = 4.5 x 10(8) to 1.0 x 10(9) photons/s; P<.001; MPanc-96: gemcitabine, mean = 4.1 x 10(9) photons/s, versus combination, mean = 2.0 x 10(9) photons/s, difference = 2.1 x 10(9) photons/s; 95% CI = 4.4 x 10(8) to 3.8 x 10(9) photons/s; P<.001).
