Today, a new study published in Nature Communications reveals a previously unknown process that could help to explain how certain genes are switched on in specific types of cells. Scientists have discovered a new form of gene regulation called cyclic RNA, which affects the expression of certain genes in different cell types. Cyclic RNA is a self-renewing cycle of gene expression that is specific to certain cell types, allowing them to express different sets of genes. This could explain how cells are able to differentiate, forming a variety of different cell types in the body. This discovery could help researchers to better understand how cells develop and how diseases like cancer arise.
