Activin <scp>B</scp> , a new player in kidney fibrosis? <sup>†</sup>
Bibliographic record
Abstract
Interest has been growing in the role of activin A in both acute and chronic kidney disease. The role of other activins, however, remains relatively unexplored. In a recent issue of The Journal of Pathology, an elegant study by Sun et al identified upregulation of INHBB, the subunit of activin B, in three different models of kidney fibrosis, as well as in human kidneys with fibrosis. This increase was shown to be mediated by upregulation of the transcription factor Sox9. Using overexpression and inhibition strategies, the importance of INHBB to kidney interstitial fibroblast activation and kidney fibrosis was clearly shown. Importantly, INHBB and Sox9 are not appreciably expressed in normal tissue. These studies lay important groundwork for the further investigation of activin B targeting as a potential therapeutic approach to attenuate kidney fibrosis. © 2021 The Pathological Society of Great Britain and Ireland.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 teacher head, not a consensus.
