WebHere, we explore the relationship between temozolomide (TMZ) response and O (6)-methylguanine DNA methyltransferase (MGMT) status in brain tumor initiating cells (BTICs). Methylation, expression, and sensitivity were assessed in 20 lines; associations were evaluated by Fisher's exact test. Some BTICs were sensitive.
