Adequate access to fresh or frozen normal adrenal tissue has been a primary limitation to the enhanced characterization of the adrenal zones via RNA sequencing (RNAseq). Herein, we describe the application of targeted RNAseq to formalin-fixed paraffin-embedded (FFPE) normal adrenal gland specimens. Immunohistochemistry (IHC) was used to visualize and guide the capture of the adrenocortical zones and medulla. Following IHC-based tissue capture and isolation of RNA, high-throughput targeted RNAseq highlighted clear transcriptomic differences and identified differentially expressed genes among the adrenal zones. Our data demonstrate the ability to capture FFPE adrenal zone tissue for targeted transcriptomic analyses. Future comparison of normal adrenal zones will improve our understanding of transcriptomic patterns and help identify potential novel pathways controlling zone-specific steroid production.

Ethnopharmacological Relevance: Huangkui capsule (HKC) is prepared with the extract of the flower of Abelmoschus manihot (L.) medic and has been used as a traditional Chinese medicine in the treatment of kidney diseases, including diabetic kidney disease (DKD).
Aim Of The Study: Our recent single-cell profile study has implicated that HKC regulates Hsd11b2 expression in renal principal cells of collecting duct, a gene crucial for glucocorticoids inactivation and mineralocorticoid receptor (MR) specificity in the kidney.

The adrenal glands are paired endocrine organs that play a vital role in maintaining homeostasis by regulating blood pressure, metabolism, electrolyte balance, and the body's response to stress. Each gland comprises the adrenal cortex, which produces steroid hormones, and the adrenal medulla, responsible for catecholamine synthesis. The cortex is further divided into three functional zones, the zona glomerulosa (mineralocorticoids), zona fasciculata (glucocorticoids), and zona reticularis (androgens), while the medulla secretes adrenaline, noradrenaline, and dopamine under sympathetic control.

This study is the first to describe posthatching morphological changes in chicken adrenal glands using histology, immunohistochemistry, transmission electron microscopy, and catecholamine levels. The study involved 30 chickens in 3 posthatching stages: Juvenile (1 day old), immature (2 months old), and mature (6 months old). The results showed no demarcation between cortical and medullary, with the interrenal tissue comprising most of the adrenal parenchyma.

Adrenal infections are considered clinically important but often go unrecognized, with a significant number of cases only diagnosed post-mortem. The limited evidence regarding imaging findings in the literature emphasizes the need to detect and diagnose these infections early in disease course to improve patient outcomes. A range of microorganisms, including fungi, viruses, parasites, and bacteria, can directly or indirectly affect the morphology and function of the adrenal glands.

Orchidectomy and estrogenization of the male represent a procedure that is applicable in sex reassignment or in prostate cancer therapy. This approach has an influence on the hypothalamic-pituitary-adrenal axis and thus affects cardiovascular function and metabolism. We utilized orchidectomized rats to evaluate the effects of estradiol on the structure and hormonal output of the adrenal gland.
