A novel combinatorial therapeutic strategy using resveratrol and viral oncolysis for diffuse intrinsic pontine glioma: an in vitro study.
In patient-derived DIPG cell lines, resveratrol pretreatment enhanced hrR3 oncolytic herpesvirus replication and reduced tumor-cell viability more than either monotherapy, alongside reduced STAT3/AKT phosphorylation and increased apoptotic markers.

In patient-derived DIPG cell lines, resveratrol pretreatment enhanced hrR3 oncolytic herpesvirus replication and reduced tumor-cell viability more than either monotherapy, alongside reduced STAT3/AKT phosphorylation and increased apoptotic markers.
Research significance
The record provides in-vitro evidence that resveratrol potentiates hrR3-mediated oncolysis in DIPG cells; it remains an inference that this combination could improve antitumor efficacy in patients, pending validation in animal models and human studies of delivery, dosing, safety, and efficacy.

UNLABELLED: Pediatric central nervous system (CNS) tumors, specifically Diffuse Midline Gliomas (DMG) are a leading cause of cancer-related deaths in children presenting an unmet need for novel therapeutic development. In this study, we assessed the combined effects of resveratrol (RSV) and the oncolytic herpes simplex virus (oHSV), hrR3 in patient-derived diffuse intrinsic pontine glioma (DIPG) cell lines. RSV or hrR3 monotherapy resulted in a dose- and time-dependent reduction in cell viability. RSV pretreatment followed by hrR3 infection led to a significantly greater reduction in tumor cell viability than monotherapy. RSV pretreatment further enhanced the replication of hrR3, as evidenced by increased viral titers. Mechanistic analysis showed that the combination therapy was associated with reduced phosphorylation of the signal transducer and activator of transcription 3 (STAT3) and protein kinase B (AKT) signaling pathways, along with increased expression of apoptotic markers, including cleaved caspase-3 and Poly (ADP-ribose) polymerase (PARP). Together these findings indicate that RSV potentiates hrR3-mediated oncolysis in DIPG cells by enhancing viral replication, suppressing survival signaling and promoting apoptosis in DIPG cells in vitro.
