SNORA73B: SNORA73B is a small nucleolar RNA (snoRNA) that has been found to be overexpressed in Huh7 cells [PMC8763008]. It is also downregulated in histone encoding genes and spliceosome-associated small nuclear ribonucleoproteins (RNP) [PMC7191197]. In the context of age-related macular degeneration (AMD), SNORA73B has been found to be expressed at higher levels in both retina and PRCS tissues compared to normal tissues, suggesting a potential role in AMD [PMC5813239]. SNORA73B is associated with SIRT7 and is involved in the processing of pre-rRNAs to produce mature rRNAs [PMC4754350] [PMC8410784]. Overexpression of SNORA73B has been shown to inhibit the expression of its host genes [PMC8763008]. The snoRNABase database provides accession numbers and approved symbols for snoRNAs, including SNORA73B [PMC1687206]. The expression of SNORA23 and SNORA73B is regulated by the AKT molecular inhibitor, GSK2141795, suggesting their involvement in the PI3K/Akt/mTOR signaling pathway [PMC8763008]. In terms of cancer prognosis, SNORA73B has been identified as a potential predicting factor for outcome in cutaneous melanoma (CM) [PMC7550331]. In summary, SNORA73B is a snoRNA that shows differential expression patterns in various cellular contexts and diseases. It plays a role in RNA processing and may have implications for AMD and cancer prognosis.
