Telomeric lncRNA TERRA localizes to stress granules in human ALT cells
Bibliographic record
Abstract
Abstract TERRA, the lncRNA derived from the ends of chromosomes, has a number of well-described nuclear roles including telomere maintenance and homeostasis. A growing body of evidence now points at its role in human cells outside of nucleus—it has been found to be a component of extracellular vesicles, a player in inflammation signalling and its capacity for translation has been shown. In this work, using a combination of sensitive microscopy methods, cellular fractionation, proteomics and transcriptome analysis, we demonstrate directly for the first time that TERRA is present in the cytoplasm of human telomerase-negative cells, especially upon various stress stimuli, and that it associates with stress granules. Confirming the presence of TERRA in the cytoplasm, our work fills an important gap in the field, and contributes to the discussion about the role of TERRA as a transcript involved in nucleo-cytoplasmic stress communication.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
