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: CONCLUSION : Taken together , these data suggest that TGF - beta1 modulates TPO - mediated effects on megakaryocytic proliferation by interfering with TPO - induced signal transduction , particularly by reducing the activities of MAPK ERK1 / ERK2 and STAT5 .
Example Output: TGF - beta1

Example Input: In contrast , ablation of either Lck - binding domain abolished the ability of Tip to stimulate NF - AT - dependent transcription .
Example Output: NF - AT

Example Input: Thus , regulation of UK - like PAs in HMy2 and GM4672A cells differs with respect to the extent to which glucocorticoids inhibit constitutively expressed activator levels , as well as the possible contribution of glucocorticoid - inducible inhibitors to the regulatory process in GM4672A cells .
Example Output:
constitutively expressed activator
