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.

Input: Consider Input:  Our data demonstrate that , in the context of this macrophage line , E12 induces expression of EBF and together these transcription factors coordinately regulate numerous B lineage - associated genes .

Output: transcription factors


Input: Consider Input:  In two lines ( OCI - AML - 1 , OCI - AML - 11 ) , TNF - alpha acted as an apoptotic agent ; in others ( HU - 3 , M - 07e , TF - 1 ) , it had the opposite effect , preventing apoptosis and inducing proliferation .

Output: TNF - alpha


Input: Consider Input:  Untreated CM - SM cells contain single class , high - affinity ( KD = 4 . 0 X 10 ( - 9 ) M ) glucocorticoid - specific receptor sites ( approximately 60 , 000 per cell ) , as measured by a whole cell assay , at 37 degrees C , using [ 3H ] triamcinolone acetonide ( TA ) .


Output: receptor sites
