    “…Instead, this strain accumulates free U4 snRNP, protein-free U6 RNA, and a novel complex containing U2/U6 di-snRNP. Further mutational analysis indicates that disruption of the U6–Prp24 interaction rather than stabilization of U2/U6 renders stable U4/U6 di-snRNP assembly nonessential. …”

    “…The investigation of the molecular mechanisms highlights a common and initial ERK1/2 activation in response to AdipoR in both Saos-2 and U2OS cells. Interestingly, a simultaneous and dramatic downregulation of p70S6K phosphorylation, one of the main targets of mTORC1 pathway, has also been observed in AdipoR-treated Saos-2, but not in U2OS cells. …”
