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:  Cytotoxic T lymphocytes directed against well - characterized epitopes of EBV latency genes represent an already successful and promising therapeutic approach to EBV - associated lymphomas , in particular PTLDs
Example Output: EBV latency genes

Example Input:  Thus , the FANCC protein functions to modulate expression of a family of genes that in normal cells are inducible only by specific environmental cues for apoptosis or mitogenic inhibition , but it does so independently of the classic IFN - STAT1 pathway and is not the direct result of reduced ICSBP expression .
Example Output: FANCC protein

Example Input:  The Il - 4 promoter / enhancer is transcriptionally inactive in B lymphoma cells and HeLa cells .
Example Output:
Il - 4
