In other tumor types, elevated PARP‐1 mRNA is associated with poor prognosis in gliomas (Li et al, 2016), PARP‐1 mRNA is elevated in colon carcinoma when compared to adenoma (Dziaman et al, 2014), PARP‐1 gene expression is associated with lymph node spread of malignant pleural mesothelioma (Walter et al, 2016), and PARP‐1 mRNA and protein are elevated in endometrial adenocarcinoma (Bi et al, 2013). Here, PARP1 is linked to glioma.
