C-reactive protein (CRP) is considered as one of the most sensitive markers of inflammation. The aim of the present study is to investigate the effects of CRP on the production of adiponectin in 3T3-L1 adipocytes. Northern and western blot analysis revealed that CRP treatment inhibited adiponectin mRNA expression and secretion in a dose- and time-dependent(More)
WNT/β-catenin signalling is involved in regulating adipogenesis, and its dysregulation occurs in obesity. Secreted frizzled-related protein 5 (SFRP5) is a WNT protein inhibitor; however, its role in adipogenesis and obesity is controversial. In this study, we observed that SFRP5 mRNA levels were increased in the fat tissues of obese humans and mice. Sfrp5(More)
Obesity occurs when excess energy accumulates in white adipose tissue (WAT), whereas brown adipose tissue (BAT), specialized for energy expenditure through thermogenesis, potently counteracts obesity. Factors that induce brown adipocyte commitment and energy expenditure would be a promising defence against adiposity. Here, we show that Lgr4 homozygous(More)
Angiotensin II (AngII) is a multifunctional bioactive peptide and previous studies have shown that the renin-angiotensin system (RAS) of both host and tumor are important in tumor growth and angiogenesis in lung cancer. Angiotensin-converting enzyme 2 (ACE2) is a newly identified component of RAS, with 42% amino acid homology to ACE. However, the expression(More)
The circadian clock plays an important role in the liver by regulating the major aspects of energy metabolism. Currently, it is assumed that the circadian clock regulates metabolism mostly by regulating the expression of liver enzymes at the transcriptional level, but the underlying mechanism is not well understood. In this study, we showed that Lgr4(More)
Obesity develops when energy intake exceeds energy expenditure. Promoting brown adipose tissue formation and function increases energy expenditure and hence may counteract obesity. Berberine (BBR) is a compound derived from the Chinese medicinal plant Coptis chinensis. Here we show that BBR increases energy expenditure, limits weight gain, improves cold(More)
Angiotensin II (AngII) is a multifunctional bioactive peptide in the renin-angiotensin system (RAS). Angiotensin-converting enzyme 2 (ACE2) is a newly identified component of RAS. The role of AngII and ACE2 in the metastasis of non-small cell lung cancer (NSCLC) and the effects on matrix metalloproteinases (MMPs) are still unknown. In the present study, the(More)
Accumulating evidence suggests that adipose tissue is the main source of pro-inflammatory molecules that predispose individuals to insulin resistance. Stevioside (SVS) is a widely used sweetener with multiple beneficial effects for diabetic patients. In this study, we investigated the effect of SVS on insulin resistance and the pro-inflammatory state of(More)
The local renin-angiotensin system (RAS) is one of the crucial components in the tumor microenvironment. Recent evidence suggests that the local RAS plays an important role in tumor metabolism, survival, angiogenesis and invasion processes. Angiotensin-(1-7) [Ang-(1-7)] is an endogenous peptide of the RAS with vasodilator(More)
Thickened pituitary stalks (TPSs) on magnetic resonance imaging (MRI) result from diverse pathologies; therefore, it is essential to make specific diagnoses for clinical decision-making. The diagnoses and indications for surgical biopsies in patients with central diabetes insipidus (CDI) and TPSs are thoroughly discussed in this paper. Thirty-seven patients(More)
