BECN1 and disseminated peritoneal leiomyomatosis: In agreement with the data obtained in muscle biopsies, leukocytes of most patients showed an increase of LC3B lipidation and of BECN1 levels after LPD (Fig. 6A and B; Fig. S3A; P = 0.042 for LC3B-II, P = 0.062 for BECN1, for the comparison between T0 and T12 in the patient cohort).
