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:  Simultaneous exposure to PPAR - gamma ligands ( e . g . 15 - deoxy - Delta ( 12 , 14 ) - prostaglandin J ( 2 ) , troglitazone ) showed drastic inhibition of proliferation and significant decreases in cell viability .

Output: PPAR - gamma


Input: Consider Input:  Using enhancer - reporter constructs , IL - 4 specifically down - regulated the NFIL - 2B element .

Output: IL - 4


Input: Consider Input:  T cell death via PPAR - gamma ligation may act as a potent anti - inflammatory signal in the immune system , and ligands could possibly be used to control disorders in which excessive inflammation occurs .


Output: PPAR - gamma
