"At least two pieces of evidence provide support for the nuclear miR-10b maturation scenario: first, the finding of Ago2 and, more recently, of Dicer in the nucleus of specific cells, including glioma (Suppementary Fig. xref a) and [ xref , xref – xref ], and second, the co-IP of the spliceosomal SART3 and PRPF8 complexes with Ago2, the core endonucleolytic components of RISC that efficiently pools-down the entire miR-10b population from glioma cells."

"Both U6 and miR-10b have been significantly enriched in the spliceosomal SART3 and PRPF8 complexes (Fig. 3a and Supplementary Fig. 4a, b)."

"These results indicate that miR-10b interferes with U6 incorporation into SART3 and PRPF8 snRNPs."

"Furthermore, miR-10b- U6 chimeras have been detected in the cross-linked and ligated SART3 and PRPF8 complexes, similar to the Ago complexes (Fig. 3b) indicative of the miR-10b interaction with U6 snRNP in the splicing complex."

"We further demonstrate that miR-10b modulates U6 N-6-adenosine methylation and pseudouridylation, U6 binding to splicing factors SART3 and PRPF8, and regulates U6 stability, conformation, and levels."
