In glioblastoma metastasis, the malignant mGSC cells express markers of mesenchymal GSC subtype (MES-GSC), such as CD44 and YK-40 and their major obstacle seems to be propagating in the in various organs' microenvironments, different from the niches that home GSCs in the primary glioblastoma.

We also found that elevated serum/plasma YKL-40 had significant prognostic effects on OS in various cancer subgroups such as gastrointestinal tumors (HR, 1.37; 95% CI 1.18-1.58), ovarian cancer (HR, 2.27; 95% CI 1.69-3.06), melanoma (HR, 1.77; 95% CI 1.18-2.67), lung cancer (HR, 1.73; 95% CI 1.35-2.23), urologic neoplasms (HR, 1.61; 95% CI 1.08-2.40) and glioblastoma (HR, 1.23; 95% CI 1.07-1.42); in contrast, the prognostic effect of serum/plasma YKL-40 was not statistically significant in breast cancer (HR, 1.07; 95% CI 0.98-1.17).

Overall, this study identifies candidate changes in secreted proteins from NF1 deficient glioma cells that could influence the tumor microenvironment, and suggests a direct link between NF1 loss and increased tumor cell production of CHI3L1 and endoglin, two factors implicated in mesenchymal identity in glioblastoma.

Meta-analysis of those studies showed that high YKL-40 expression was associated with worse overall survival in glioblastoma patients (HR = 1.46, 95%CI 1.33-1.61, P < 0.001).

Therefore, YKL‑40 may be a novel key molecule in addition to MGMT, that is responsible for TMZ resistance in glioblastoma cell lines and could be a new target to overcome TMZ resistance in recurrent glioblastomas in the future.

Neither SAGE nor Northern analysis revealed the presence of HC gp-39 mRNA in the glioblastoma cell line, thus the detection of increased quantities of this mRNA in GBMs may be associated with activated macrophages.
