Brown adipose tissue thermogenesis in humans [PDF]

Diabetologia, 2013
The prevalence of obesity and type 2 diabetes is at epidemic proportions. Classical interventions aimed at targeting obesity, such as reducing energy intake or increasing exercise, are often not effective over the long term. In contrast to white adipocytes, which store energy, brown adipocytes generate heat via mitochondrial uncoupling protein 1 ...

Loss of Hepatic Angiotensinogen Attenuates Diastolic Dysfunction in Heart Failure with Preserved Ejection Fraction

Advanced Science, EarlyView.
Increased hepatic angiotensinogen (AGT) abundance leads to cardiac diastolic dysfunction via the AngII‐independent pathway. Liver‐derived AGT is internalized by LRP2 in cardiac endothelial cells, subsequently contributing to myocardial diastolic dysfunction by suppressing microvascular angiogenesis via inhibiting the GATA2/Pim3 pathway.

Hepatic KLF9 Deficiency Inhibits Dehydroepiandrosterone (DHEA)‐Induced Polycystic Ovary Syndrome via Liver‐Ovary Axis

Advanced Science, EarlyView.
The study shows that liver is a previously unrecognized extraovarian organ that plays a key role about androgen homeostasis in the development of DHEA‐induced PCOS. DHEA is the most common precursor of active androgen, such as DHT, and KLF9 is required for the conversion of DHEA to DHT and hepatic KLF9 might be a potential therapeutic target for PCOS ...

Brown Adipose Tissue in Cetacean Blubber

PLOS ONE, 2015
Brown adipose tissue (BAT) plays an important role in thermoregulation in species living in cold environments, given heat can be generated from its chemical energy reserves. Here we investigate the existence of BAT in blubber in four species of delphinoid cetacean, the Pacific white-sided and bottlenose dolphins, Lagenorhynchus obliquidens and Tursiops

Hsa_circ_0026782 Acts as a “Molecular Break” of CREB1‐Mediated Transcription by Promoting Its Phosphorylation at Ser142 That Prevents Keloid Progression

Advanced Science, EarlyView.
Model for the role of hsa_circ_0026782/p‐CREB1 (Ser142) played in keloid. Hsa_circ_0026782 is derived from back‐splicing of ITGA7 exon 4. When hsa_circ_0026782 binds to CREB1, the exposure of the bZIP domain and dimerization of CREB1 are promoted (upper left).

Activation of classical brown adipocytes in the adult human perirenal depot is highly correlated with PRDM16-EHMT1 complex expression.

PLoS ONE, 2015
Brown fat generates heat to protect against cold and obesity. Adrenergic stimulation activates the thermogenic program of brown adipocytes. Although the bioactivity of brown adipose tissue in adult humans had been assumed to very low, several studies ...

Electron Density of Adipose Tissues Determined by Phase-Contrast Computed Tomography Provides a Measure for Mitochondrial Density and Fat Content

Frontiers in Physiology, 2018
Phase-contrast computed tomography (PCCT) is an X-ray-based imaging method measuring differences in the refractive index during tissue passage. While conventional X-ray techniques rely on the absorption of radiation due to differing tissue-specific ...

Deficiency of Leucine‐Rich Repeat Containing G Protein‐Coupled Receptor 4 in Pancreas Reduces β Cell Mass

Advanced Science, EarlyView.
In islet β cells, LGR4 binds with Rspondin to activate the Wnt‐β‐catenin‐Ccnd1 axis, leading to a subsequent increase in cell proliferation. On the other hand, LGR4 also binds with RANKL, thus suppressing the phosphorylation of p44/p42 MAPK and p65 NF‐κB and subsequent cell apoptosis.

Nonalcoholic Fatty Liver Disease Exacerbates the Advancement of Renal Fibrosis by Modulating Renal CCR2+PIRB+ Macrophages Through the ANGPTL8/PIRB/ALOX5AP Axis

Advanced Science, EarlyView.
The ANGPTL8/PIRB/ALOX5AP axis mediates liver‐kidney crosstalk. Hepatocytes secrete ANGPTL8, which binds to CCR2+PIRB+ macrophages in the kidneys, affecting the expression of ALOX5AP and enhancing the activation of these macrophages. Activated cells produce TGF‐β, IL‐6, and IL‐23, driving Th17 activation and promote the formation of myofibroblasts ...
