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:  We used several agents active on signal transduction pathways in cytokine expression , such as the protein kinase C inhibitor staurosporin , antioxidant agents including N - acetyl cysteine ( NAC ) and pyrrolidine dithiocarbamate ( PDTC ) , and p38 mitogen - activated protein kinase ( MAPK ) inhibitor SB203580 .

SOLUTION: protein kinase C

PROBLEM:  Phosphorylation was not associated with the induction of cAMP , and inhibition of PKA signaling had no effect on P - CREB .

SOLUTION: P - CREB

PROBLEM:  Therefore , the SART3 antigen and its peptides could be an appropriate molecule for use in specific immunotherapy of the majority of HLA - A24 - positive breast cancer patients

SOLUTION:
SART3 antigen
