SCFAs also play a role in synergistic therapy and efficacy sensitization, including synergizing with curcumin and quercetin to induce apoptosis in GBM cells [111,112], enhancing glioma sensitivity to herpes simplex virus thymidine kinase (HSV-TK)/ganciclovir gene therapy by promoting a bystander effect in glioma cells [113], and increasing the sensitivity of glioma to radiotherapy [114]. Here, TKT is linked to glioma.
