Web26 Apr 2024 · Here, we make a detailed study of TERT across the Animal Kingdom using extant data to look for evidence (or lack) of patterns of TERT protein and alternative splicing evolution. We identify TERTs across animal phylogeny and perform within and between phyla comparison of the structure of this gene. WebRNA splicing is a fundamental feature of the processing of RNA in many organisms. The pre-rRNA of Tetrahymena thermophila was found to undergo ‘self-splicing’ in vitro without the need for a protein catalyst and it was one of the first RNA molecules to be discovered to have enzymatic activity. 1 This and other ‘group I’ self-splicing ribozymes promote two …

Web31 Jul 2024 · TERT Splicing in MTC. A study of 42 MTC tumors found TERT expression and telomerase activity in 50% (21/42) of the tumors. And, over two-thirds of the telomerase positive cancers (15/21) showed expression of the full-length TERT transcript, higher telomerase activity and were associated with a significantly shorter patient survival time . WebThree KMT2B integrations were also identified between exons 3–6, which increased the mRNA expression and altered the transcript structure through alternative splicing or intron retention (online supplemental figure 12A,C). Overall, TERT promoter integrations were enriched in non-proliferative tumours (p=0.007; figure 4D).
