Deleted in cancer 1 (DICE1) is an essential protein controlling the topology of the inner mitochondrial membrane in <i>C. elegans</i>
Bibliographic record
Abstract
DICE1 (deleted in cancer 1), first identified in human lung carcinoma cell lines, is a candidate tumor suppressor, but the details of its activity remain largely unknown. We have found that RNA interference of its C. elegans homolog (DIC-1) produced inviable embryos with increased apoptosis, cavities in cells and abnormal morphogenesis. In the dic-1(RNAi) germ line, ced-3-dependent apoptosis increased, and cell cavities appeared at the late-pachytene/oogenic stage, leading to defective oogenesis. Immunofluorescence microscopy of DIC-1 revealed its ubiquitous expression in the form of cytoplasmic foci, and cryoelectron microscopy narrowed down the location of the foci to the inner membrane of mitochondria. After dic-1 RNAi, mitochondria had an irregular morphology and contained numerous internal vesicles. Homozygous embryos from a heterozygous dic-1 mother arrested at the L3 larval stage, in agreement with the essential role of DIC-1 in mitochondria. In summary, C. elegans DIC-1 plays a crucial role in the formation of normal morphology of the mitochondrial cristae/inner membrane. Our results suggest that human DICE1 may have several functions in multiple intracellular locations.

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.
