Increased expression levels of PIEZO1 in visceral adipose tissue in obesity and type 2 diabetes are triggered by mechanical forces and are associated with inflammation.

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
backgroundPIEZO1 has emerged as a mechanoreceptor linked with adipogenesis, adipose tissue (AT) inflammation and insulin resistance. We aimed to determine the impact of obesity and obesity-associated type 2 diabetes (T2D) as well as mechanical compression forces on the expression of PIEZO1 in visceral AT (VAT) and its relation with inflammation.
methodsBlood and VAT samples were obtained from 100 volunteers. Static compression studies in VAT explants were performed to study the PIEZO1 response. The effect of bariatric surgery on the expression of Piezo1 was assessed in a rat model of diet-induced obesity.
resultsObesity and obesity-associated T2D increased (P < 0.01) gene expression levels of PIEZO1 in VAT mainly due to adipocytes. SWELL1 and key markers of inflammation (NLRP3, NLRP6, IL1B, IL18 and IL8) were also upregulated in VAT in obesity and T2D being significantly associated (P < 0.01) with PIEZO1 levels. We further showed that the static compression of VAT explants promoted an upregulation of PIEZO1 (P < 0.01) and SWELL1 (P < 0.01) expression levels together with a strong increase in the expression and release of key inflammatory mediators. The treatment of THP-1-derived macrophages with the secretome of adipocytes from patients with obesity upregulated (P < 0.001) PIEZO1 levels. Rats undergoing bariatric surgery exhibited decreased (P < 0.01) expression levels of Piezo1 in the epididymal AT.
conclusionsStatic compression triggered an upregulation of PIEZO1 in VAT explants together with a strong inflammation. In addition, the increased expression of PIEZO1 in VAT in obesity and obesity-associated T2D, primarily attributable to adipocytes, is closely associated with SWELL1 and inflammatory markers.
