Background and Objective: Long non-coding RNAs (lncRNAs) are a class of non-coding RNAs with a length of more than 200 nucleotides. Multiple studies have shown that lncRNAs are important molecules participating in cellular homeostasis. In fact, it is well known that lncRNAs are often dysregulated in diseases such as cancers. Cancer is a multistep and multifactorial disease. One of the processes that requires further attention is drug or chemoresistance in cancers. LncRNAs are involved in drug resistance as well. Among the different identified lncRNAs, the lncRNA XIST has emerged as a promising biotarget. Therefore, this review is aimed at reviewing the literature to identify the studies reporting on the involvement of XIST in chemoresistance. Key contents and Findings: XIST is involved in the mechanism of various chemotherapeutic drugs involving a lot of cancers. Most of the reported studies suggest a network of XIST-miRNA pathways that are altered in chemoresistant cancers. Conclusion: Based on the available literature, XIST is a promising target for chemoresistance. However, further in-depth studies are needed to validate these findings.
