Abstract

Malignant gliomas are highly aggressive primary brain tumors for which the therapeutic efficacy of cisplatin is frequently limited by intrinsic or acquired drug resistance. Despite advances in adjuvant therapies, overcoming chemoresistance remains a major challenge in the treatment of these malignancies. Emerging evidence indicates that long non-coding RNAs (lncRNAs), a class of non-protein-coding transcripts involved in gene regulation, play important roles in modulating treatment responses. Several lncRNAs, including differentiation antagonizing non-protein-coding RNA (DANCR), HOXD antisense growth-associated long non-coding RNA (HOXD-AS1), MEG3, MALAT1, and HOTAIR, have been implicated in pathways associated with glioma progression and therapeutic resistance. In particular, DANCR has been reported to promote cisplatin resistance in glioma cells through suppression of apoptosis and activation of pro-survival signaling pathways. This review summarizes current evidence regarding the roles of lncRNAs in cisplatin resistance, highlighting mechanisms such as regulation of drug transport, DNA damage repair, apoptosis, cancer stem-cell maintenance, and signaling pathways associated with treatment adaptation. We also discuss current limitations, challenges for clinical translation, and gaps in the existing evidence. A better understanding of lncRNA-mediated resistance mechanisms may facilitate the identification of novel therapeutic targets and inform future studies aimed at overcoming cisplatin resistance in malignant gliomas. © 2026 by the authors.
