SNORD44: SNORD44 is a small nucleolar RNA (snoRNA) that is part of a group of small noncoding RNAs, including small nuclear RNA and small nucleolar RNA [PMC4793896]. In a study, LNATM PCR primer sets were used to analyze miR expression, and the relative quantification of specific miRs to SNORD44 was carried out [PMC8728617]. Another study investigated the binding of SNORD44 sdRNAs or the long form to FBL [PMC4159348]. In the context of aging and osteoarthritis (OA), it was found that SNORD26 was increased in OA, while SNORD44 and SNORD78 were reduced in aging [PMC7326970]. Additionally, SNORD44 (RNU44) has been identified as significantly associated with distant disease-free survival in breast cancer, suggesting its potential as a biomarker for metastatic progression [PMC9818347]. Furthermore, concentrations of non-coding small nuclear RNAs like SNORD44 have been used for sample-to-sample normalization in certain studies [PMC4813272]. Lastly, miRNA expression data were normalized to the expression levels of SNORD25, SNORD44, and SNORD68 in a study that compared different groups [PMC4431491].
