Brief Summary: This study demonstrates that FADS2 is a major regulator of steroidogenesis in the adrenal gland due to its key role in shaping the lipidomic landscape of adrenocortical cells.Comment: The corticosteroids aldosterone and cortisol are produced in the zona glomerulosa and zona fasciculata of the adrenal cortex, respectively (1, 2). Excess production of aldosterone in primary hyperaldosteronism results in resistant hypertension and cardiovascu...

Brief Summary: This study explored the relationship between Somatostatin Receptor 2 (SSTR2) immunoreactivity and succinate dehydrogenase complex iron sulfur subunit B (SDHB) immunoreactivity, mutational status, and clinical behavior of paragangliomas (PPGLs), and evaluated SSTR-based therapies in metastatic PPGLs. The findings highlight SSTR2 expression as a novel biomarker for metastatic behavior in PCC, PGL and SDHB/ SDHx mutations. They also suggest that SSTR-based therapie...
