Investigation reveals how glioblastoma cells respond to temozolomide, suggesting therapeutic strategies.

This research aims to understand how glioblastoma cells develop resistance to temozolomide and how their behavior changes in different environments.
Developed a 3D gelatin hydrogel model to mimic the tumor microenvironment.
Studied mixed populations of temozolomide-sensitive and resistant glioblastoma cells.
Utilized different dosing regimens of temozolomide, including physiological and metronomic schedules.
Examined the effects of combining temozolomide with an MGMT inhibitor, lomeguatrib.
Heterogeneous cell populations exhibited varying responses to temozolomide treatment.
Combination therapy with lomeguatrib significantly modulated drug resistance in vitro.
The 3D model enhanced the understanding of glioblastoma cell migration and phenotypic plasticity.

Kriuchkovskaia et al. (2026) studied this question.
