1 · What the graph read from it

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.

2 · The registry

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

purposeCatecholamines (CA) play a major role in metabolism and immune response. Recent reports showing adipose tissue can synthetize CA enlighten new roles for these amines in obesity. This study aimed to evaluate the expression of both tyrosine hydroxylase (TH) and phenylethanolamine N-methyltransferase (PNMT) and CA content along preadipocytes differentiation, under normal and obesigenic conditions.

methods8-9 week-old male C57BL/6 mice were divided in two groups: one fed with a high-fat diet (HFD) and other with a standard diet (SD) for 20 weeks. Afterwards, both TH and PNMT expression, localization, and CA content in adipocytes, were evaluated.

resultsqPCR results showed no changes for TH and PNMT expression during the differentiation process for visceral and subcutaneous preadipocytes from mice fed with SD. Comparing to SD, HFD increased TH gene expression of subcutaneous preadipocytes and PNMT gene expression of both visceral preadipocytes and adipocytes. HPLC-ED analyses revealed HFD increased visceral adipocytes noradrenaline intracellular content comparing with preadipocytes (p = 0.037). When compared with SD, HFD raised and decreased noradrenaline content, respectively, in visceral adipocytes (p = 0.004) and subcutaneous preadipocytes (p = 0.001). Along the differentiation process, HFD increased visceral adrenaline intracellular content comparing with SD (p < 0.001). HFD increased visceral comparing to subcutaneous adrenaline content for both preadipocytes (p = 0.004) and adipocytes (p = 0.001).

conclusionsTH and PNMT expression in adipose tissue is differently modulated in visceral and subcutaneous adipose depots, and seems to depend on diet. Differences observed in visceral adipose CA handling in HFD-fed mice might uncover novel pharmacological/nutritional strategies against obesity and cardiovascular risk.
