Cellular and molecular mechanisms of neuronal loss in Atrx-knockout mice
Bibliographic record
Abstract
Atrx is a member of the SNF2 family of chromatin remodeling proteins that functions by remodeling or repositioning nucleosomes at specific target genes using the energy from ATP hydrolysis. Mutations in the gene encoding Atrx cause the human ATR-X syndrome, an X-linked disorder that is associated with severe mental retardation. We have shown that targeted deletion of this gene in experimental mouse models results in the loss of neuronal cell populations in the central nervous system (CNS). Compromised neuronal survival in Atrx mutants may underlie the intellectual impairment and cognitive deficits observed in ATR-X syndrome. We have generated transgenic mice in which interneurons critical for modulation and integration of synaptic activity in the retina are selectively lost. We are using this model system to delineate the cellular and molecular mechanisms of neuronal cell loss in Atrx mutants. To determine the neuronal circuitry and genetic regulation underlying the loss of retinal interneurons in mice lacking the chromatin remodeling protein Atrx.

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.
