11-Oxygenated Androgens Inhibit Brown Adipose Tissue Differentiation.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
contextWomen with polycystic ovary syndrome (PCOS) and PCOS animal models have diminished brown adipose tissue (BAT) activity, potentially contributing to metabolic dysfunction. Besides classical androgens, adrenal 11-oxygenated androgens are elevated in women with PCOS. However, it remains unknown whether these 11-oxygenated androgens affect BAT metabolism.
objectiveTo study the effects of 11-ketotestosterone (KT) and 11-ketodihydrotestosterone (KDHT) on BAT metabolism.
methodsThe female mouse brown adipocyte cell line T37i was treated with increasing concentrations (0.1-10 µM) of testosterone (T), dihydrotestosterone (DHT), KT, or KDHT during or after differentiation. In addition, female mice received a daily injection of vehicle, DHT, KT, or KDHT (100 µg) for 1 day or 1 week. Adipose depots were collected for RNA sequencing (RNAseq) analysis and Gene Set Enrichment Analysis (GSEA).
resultsDuring differentiation, T, KT, DHT, and KDHT treatment of T37i cells dose-dependently reduced lipid droplet accumulation, and downregulated mRNA expression of adipogenic markers by up to 50%, with KDHT having the weakest effect. In mature T37i cells, only the high concentrations of these androgens exhibited inhibitory effects. RNAseq analysis revealed that DHT exposure induced the most differentially regulated genes in BAT, followed by KT and KDHT treatment. GSEA indicated that 1-day treatment with DHT and KT, but not KDHT, resulted in the downregulation of metabolic pathways in BAT.
conclusion11-Oxygenated androgens at high concentrations directly inhibit brown adipocyte differentiation in vitro and KT acutely downregulates BAT metabolic transcriptome in vivo, a result not observed with KDHT. These findings suggest that elevated 11-oxygenated androgens may impair BAT function, contributing to metabolic complications associated with hyperandrogenic conditions, including PCOS.
