Stearoyl-CoA desaturase inhibition blocks formation of hepatitis C virus-induced specialized membranes
Bibliographic record
Abstract
Hepatitis C virus (HCV) replication is dependent on the formation of specialized membrane structures; however, the host factor requirements for the formation of these HCV complexes remain unclear. Herein, we demonstrate that inhibition of stearoyl-CoA desaturase 1 (SCD-1) halts the biosynthesis of unsaturated fatty acids, such as oleic acid, and negatively modulates HCV replication. Unsaturated fatty acids play key roles in membrane curvature and fluidity. Mechanistically, we demonstrate that SCD-1 inhibition disrupts the integrity of membranous HCV replication complexes and renders HCV RNA susceptible to nuclease-mediated degradation. Our work establishes a novel function for unsaturated fatty acids in HCV replication.

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.
