Abstract
N6-methyladenosine (m6A) RNA methylation, a dynamic regulator of transcript expression, plays a pivotal role in cancer by influencing diverse mRNA processes, including nuclear export, splicing, translation and decay. It intersects with cancer biology, impacting progression, treatment sensitivity and prognosis. Platinum-based compounds are essential in cancer treatment, while intrinsic or acquired resistance poses a formidable challenge, limiting therapeutic efficacy. Recent breakthroughs have established a direct association between m6A RNA methylation and platinum resistance in various cancer types. This review summarized related studies, aiming to provide profound insights into the interplay between m6A-associated regulation and platinum-resistance mechanisms in cancer. It explores therapeutic approaches, including personalized treatments based on m6A profiles, guiding future research to enhance clinical strategies for oncological prognostic outcomes.
Plain language summary
Cancer poses a global health challenge, with platinum-based drugs as a cornerstone of treatment. Regrettably, cancer cells can develop resistance to these drugs, diminishing their effectiveness. Recent research suggests that a subtle modification known as N6-methyladenosine (m6A) on RNA molecules may contribute to this resistance. m6A acts as a minuscule tag on RNA molecules within the cells, akin to a genetic switch. When altered, it can render cancer cells less responsive to platinum-based drugs. Scientists have found that m6A changes in various cancer types can bolster resistance to platinum-based drugs. This reduced drug efficacy presents a significant concern, as platinum-based drugs are vital in treating diverse cancer types, including ovarian, lung and colorectal cancer. Understanding the impact of m6A on platinum resistance is pivotal. It may enable doctors to identify patients less likely to respond to treatment. Researchers are also investigating methods to target m6A alterations in cancer cells, potentially rendering them more receptive to platinum-based drugs. Ongoing research into m6A and its role in platinum resistance holds promise for enhancing cancer treatments, ultimately increasing the chances of success for patients requiring platinum-based drugs.
