Input: Consider Input:  CONCLUSIONS : These results suggest that , by interacting with cellular transcription factors and cofactors , vIRF - 2 may modulate the expression of the early inflammatory genes and potentially deregulate the immune system .

Output: vIRF - 2


Input: Consider Input:  Two adjacent , highly homologous endoglucanase genes , celD and celE from Fibrobacter succinogenes S85 , which were separated by an AT - rich 223 - nucleotide intergenic region were characterized .

Output: homologous endoglucanase genes


Input: Consider Input:  ES cells in which the gene for the erythroid transcription factor GATA - 1 has been disrupted fail to produce mature erythroid cells either in vivo or in vitro .


Output: GATA - 1
