Background: Molecular mechanisms of malignant adrenocortical tumorigenesis remain elusive despite previous comprehensive genomic studies. Nonetheless, cellular heterogeneity of primary, recurrent and metastatic adrenocortical carcinoma (ACC) haven’t been fully investigated.Aim: To characterize the molecular profile of different cell subtypes in primary, recurrent and metastatic ACC by single-nuclei RNA sequencing (snRNA-Seq), using adult human norma...

BackgroundAdrenocortical carcinoma (ACC) is a rare but devastating tumour of the adrenal gland and the molecular mechanisms of pathogenesis remain incompletely understood. To gain novel insights into the cellular landscape of ACC, we compared single nuclei RNA sequencing (snRNA-seq) datasets from ACC and normal adrenal glands (NAGs).Methods: We isolated single nuclei from 12 ACC snap-frozen samples, including 6 primary tumours, 3 local r...

Background: Molecular mechanisms underlying the pathogenesis of adrenocortical adenomas (ACAs) and autonomous cortisol secretion remains frequently unexplained despite previous comprehensive genomics studies.Aim: To gain novel insights into molecular pathogenesis of adrenocortical tumours by investigating transcriptome profiles of ACAs at single-nuclei resolution (snRNA-Seq), using adult human normal adrenal glands (NAGs) as reference.<p class="abste...

Background: Genetic alterations underlying the pathogenesis of autonomous cortisol secretion and early adrenocortical tumorigenesis have been identified in 40% of adrenocortical tumors (ACT). Nonetheless, the molecular events leading to development of ACT and steroid secretion remain obscure for a large proportion of patients.Aim: Aims of our study were to investigate the relationship between transcriptome profile and genetic background in a large series...
