Study shows how m6A regulators influence metabolic heterogeneity of hepatocellular carcinoma Cancer cells acquire growth advantages over normal cells in myriad ways. Changes in cell programming allow these cells to grow in an uncontrolled fashion, thereby forming the cancer mass. Hepatocellular carcinoma (HCC), being highly malignant and invasive with a high recurrence rate and drug-resistant phenotype, is one of the most dreadful cancers. Understanding the underlying molecular mechanisms is crucial to design therapeutic interventions and to predict patient prognosis. Cancer cells use metabolic, immunogenic, or growth-related strategies, which can be controlled by a number of alterations in the cell process. Of these, "post-transcriptional RNA modification" has recently sparked interest among cancer biologists. N6-methyladenosine (m6A) methylation, a type of RNA modification, remains the most abundant epigenetic (non-DNA related) modification in eukaryotic cells.
