To study the regulatory mechanism of gp91phox gene expression in eosinophils, we transiently transfected eosinophil-committed HL-60-C15 cells with gp91phox promoter constructs , and identified a negative element from bp -267 to -246 of the gp91phox gene , the deletion of which caused an 83% increase in promoter activity .
 DNA: gp91phox gene; DNA: gp91phox promoter constructs; DNA: gp91phox gene; cell line: eosinophil-committed HL-60-C15 cells; DNA: -267 to -246; DNA: negative element
Given options, please tell me the categories of all the listed entity words.Output format is "type1: word1; type2: word2". 
Option: cell line, protein, RNA, DNA, cell type
