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:  Fatty acids are ligands for peroxisome proliferator - activated receptor - gamma ( PPARgamma ) , and the upregulation of adipophilin mRNA by PPARgamma agonists like 15d - PGJ ( 2 ) and ciglitazone indicates that PPARgamma may mediate the induction of adipophilin expression in human blood monocytes .
Example Output: adipophilin mRNA

Example Input:  Intense interest is focused on PPAR - gamma and its ligands owing to its putative role in adipocyte differentiation .
Example Output: PPAR - gamma

Example Input:  Signal transduction from RAGE to NF - kappaB involved the generation of reactive oxygen species , since reporter gene expression was blocked with the antioxidant N - acetyl - L - cysteine .
Example Output:
NF - kappaB
