Implication

Exploratory study examines OCTN1's role in immune response and treatment outcomes in ulcerative colitis patients, suggesting potential for precision medicine.

Key Points

This research aims to explore the impact of OCTN1 variants on innate immune responses and their predictive value for treatment outcomes in ulcerative colitis patients receiving anti-TNFα therapy.
Combined preclinical studies using OCTN1 knockdown and variant-specific overexpression in THP-1 cells and primary monocytes.
Evaluated interleukin-1β production following bacterial stimulation and assessed clinical outcomes in UC patients on anti-TNFα.
Applied logistic regression and machine learning analysis to identify predictors of therapy response.
OCTN1-deficient cells showed reduced interleukin-1β secretion, while the 503F variant led to increased cytokine release.
In a clinical cohort of 105 UC patients, the homozygous 503F genotype was associated with higher rates of steroid-free remission and therapy persistence.
Machine learning models showed moderate predictive performance (AUC 0.60-0.72), with OCTN1 ranking among key factors influencing therapeutic success.
