The mechanism of action of oncogenes in acute myeloid leukaemia is poorly understood. A study now shows that the fusion oncoprotein AML1-ETO regulates leukaemogenesis by increasing the expression of small nucleolar RNAs through post-transcriptional mechanisms, resulting in increased ribosomal RNA methylation, protein translation, and promotion of leukaemic-cell self-renewal and growth.

Urinary bladder cancer (UBC) is the ninth most common cancer worldwide. Despite the reliance of UBC therapy on definite pathological grading and classifications, the clinical response among patients varies widely. The molecular basis of this type of cancer appeals to considerable research; hence, new diagnostic and therapeutic options are introduced.

Small nucleolar RNAs (snoRNAs) are noncoding RNAs primarily known for guiding chemical modifications of RNA, but their broader cellular roles and contributions to human diseases remain elusive. This In Focus article introduces the development of snoRNA-enriched kethoxal-assisted RNA-RNA sequencing (snoKARR-seq), a transcriptome-wide approach to uncover snoRNA targets with enhanced sensitivity and specificity. This method revealed an unexpected role for snoRNAs in protein translocation and secretion, expanding our understanding of their noncanonical functions.

Breast cancer (BC) is one of the most prevalent forms of cancer globally, and has recently become the leading cause of cancer-related mortality in women. BC is a heterogeneous disease comprising various histopathological and molecular subtypes with differing levels of malignancy, and each patient has an individual prognosis. Etiology and pathogenesis are complex and involve a considerable number of genetic alterations and dozens of alterations in non-coding RNA expression.

In eukaryotes, nearly 2% of the genome represented by the coding proteins. However, emerging evidence suggest more than 75% of the human genome referred to as noncoding part also plays a crucial role in governing major regulatory pathways. Noncoding RNAs can be categorized into several groups, such as microRNAs (miRNAs), small nuclear RNA (snRNAs), small nucleolar RNA (snoRNAs), transfer RNA (tRNA), and circular RNA (circRNAs), which contribute to this regulatory landscape.
