Adipose tissue has emerged as an important regulator of whole-body metabolism, and its capacity to dissipate energy in the form of heat has acquired a special relevance in recent years as potential treatment for obesity. Altogether, we have elucidated a mechanism implicated in physiological BAT activation that has potential clinical implications for the treatment of obesity and related what is a r group in biology such as diabetes. Accumulation of fat in adipose tissue is essential to store energy and insulate the body; however, excessive body fat what is a r group in biology to obesity.

Of the 2 existing types of adipose tissue, white adipose tissue WAT stores energy, whereas brown adipose tissue BAT can produce heat. Our results suggest that these 2 firebase crud operations in android of the p38 family have opposite roles what is a r group in biology controlling thermogenesis.

Obesity is a serious worldwide health problem, associated with a higher risk of life-threatening diseases [ 2 ], that has had a dramatic increase in prevalence [ 1 ]. As the main organ for fat storage, adipose tissue has a fundamental role in metabolism [ 3 ]. What is a r group in biology white adipose tissue WAT stores energy in the form of triglycerides and releases free fatty acids on demand, brown adipose tissue BAT burns fat to maintain the temperature in a process called non-shivering thermogenesis [ 4 ].

Classically, it was assumed that in adult humans BAT played a minor role in energy metabolism. However, recent findings have indicated that this tissue can be modulated by several stimuli presenting lower activity in individuals with obesity [ 5 — 7 ]. Additionally, under certain stimuli, WAT can increase its thermogenic capacity in a process called browning [ 8 — 11 ]. This remodelling of WAT has acquired special interest because it has important therapeutic implications in the treatment of obesity [ 1213 ].

The p38MAPK pathway is activated during browning, and it has been suggested that this drives adipose tissue remodelling [ 1415 ]. Because the what is a r group in biology of adipose tissue is reduced in obesity [ 6721 ], we wondered whether expression of this kinase changes in human WAT during obesity. In visceral fat and sWAT from individuals with obesity and those without obesity, we found that expression of Mapk14 correlated positively with the levels of Ucp1 Fig 1C and 1E.

See also S1 Data. This reduction in fat accumulation was associated with higher energy expenditure and slight increase of body temperature S2G and S2H Fig. In fact, these mice presented lower blood glucose levels in fasted and fed conditions S2D Fig and increased glucose tolerance S2E Figwith no differences in insulin sensitivity or insulin-stimulated glucose transporter type 4 GLUT4 translocation in adipose tissue S2E and S2F Fig. Data are presented as the increase above initial weight left panel or as total weight comparing mice fed an HDF with mice fed an ND right panel.

Location of GLUT4 was analysed in mice treated without or with insulin 1. Cartoon explaining the protocol is shown in the left panel. BrdU incorporation into the nuclei was detected by immunofluorescence in eWAT sections right panel. Cell outlines were stained with anti-perilipin antibody green and nuclei, with DAPI blue.

Quantification of positive What is a r group in biology nuclei is showed in the middle panel. FI and EE left over 2 days were corrected by lean mass. Lower panels show representative infrared thermal images. Quantification is shown in the lower panel. In agreement with our previous results, these mice were protected against HFD-induced obesity and presented lower fat mass and increased temperature.

Furthermore, they had lower blood glucose levels and partial glucose tolerance, indicating that they were protected against HFD-induced diabetes Fig 4A—4F. At this temperature, BAT is already fully differentiated; because it is complicated to detect an even higher level of UCP1, genetic modifications that up-regulate UCP1 levels cannot be easily detected [ 25 ]. To gain insight into the molecular what is a r group in biology that might account for increased UCP1 levels and thermogenic capacity, we studied the signalling in the different adipose tissue depots.

Therefore, we evaluated the expression and phosphorylation state of the other what is a r group in biology, with a phospho-p38 antibody that recognises all p38 isoforms [ 30 ]. Primary adipocytes isolated from intercapsular BAT were differentiated in vitro. Nonmitochondrial respiration was subtracted from OCR values, and all values were normalised to protein content. Graphical abstract summarising the role of p38 isoforms in adipose tissue. In this scenario, p38MAPK signalling has been proposed to be a key activator of these processes.

Consequently, there is an increasing interest to understand the function of this pathway in the regulation of adipose tissue metabolism, remodelling, and browning. A growing number of studies have defined p38MAPK as one of the main pathways that stimulates browning and BAT thermogenesis [ 1821 — 23 ]. This is in accordance with results observed in mouse models, in which we found a decrease of all p38s after HFD in all fat depots. However, the levels of UCP1 expression in these human fat depots is quite low judging by the low Ct obtained higher than 29and evaluation of UCP1 protein expression in human fat depots would be necessary.

Moreover, further studies to determinate the expression of p38 family members and upstream kinases in other human fat depots would help us to understand the role of these kinases in human adipocytes. In fact, it has been shown that p38 isoforms can compensate for each other [ 30 ]. In fact, our data suggest that these what does to link mean are more glucose tolerant using a dose of glucose based on their total body weight.

Due to the potential clinical implications of these results, it would be necessary to further evaluate the function of each p38 family member in browning to better understand how this pathway controls adipose tissue metabolism. Data were collected on demographic information age, sex, and ethnicityanthropomorphic measurements BMIsmoking and alcohol history, coexisting medical conditions, and medication use.

For fat expansion measurement, mice were treated with BrdU 0. For some experiments, cultures were incubated with nM T3 for 48 hours before extraction. Primary brown preadipocytes were plated and differentiated in gelatin-coated 0.

Nuclei were stained with DAPI, and slides were mounted with Vectashield mounting medium Vector Laboratories and examined using SP5 multi-line inverted confocal microscope.

Several confocal images of each tissue section were acquired and analysed for the translocation of GLUT4 or the presence of Ki67 or BrdU in adipocyte nuclei. Adipocyte nuclei were identified by their location inside adipocyte membranes as described [ 23 ]. Location of GLUT4 was analysed in mice treated with or without insulin 1. ND-fed mice were examined in a metabolic cage over a 3-day period to measure EE.
