NIMA-Related Kinases Defective in Murine Models of Polycystic Kidney Diseases Localize to Primary Cilia and Centrosomes
Bibliographic record
Abstract
A key feature of the polycystic kidney diseases is aberrant cell proliferation, a consequence of dysfunctional ciliary signaling. The NIMA-related kinases (Nek) Nek1 and Nek8 carry the causal mutations of two of the eight established mouse models of polycystic kidneys. Nek proteins have roles in cell cycle and may contribute to coordinate regulation of cilia and cell-cycle progression. Herein is reported that in a mouse kidney epithelial cell line, mNek1 localizes to centrosomes in interphase and remains associated with the mitotic spindle pole during mitosis. In contrast, mNek8 localizes to the proximal region of the primary cilium and is not observed in dividing cells. Knockdown of mNek8 by siRNA does not affect ciliary assembly. Taken together with the phenotypes of the mutant mice, these data suggest that mNek1 and mNek8 provide links between cilia, centrosomes, and cell-cycle regulation.

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.
