Asprosin induces acute pro-inflammatory effects on THP-1 macrophages

Shabir Kiran , Brown James , Randeva Harpal , Kyrou Ioannis

Introduction: Asprosin is a novel adipokine that is released in response to fasting and can elicit orexigenic and glucogenic effects. Circulating asprosin levels are elevated in a number of cardio-metabolic diseases, including obesity and type 2 diabetes mellitus. In vitro studies have reported pro-inflammatory effects of asprosin in pancreatic β-cells and skeletal muscle cells, which appear to be mediated via a toll-like receptor 4 (TLR4) mediated pathway, and m...

Self-reported health related quality of life and depression in women with polycystic ovary syndrome: associations with selected metabolic and hormonal PCOS features.

Vrbikova Jana , Hill Martin , Vankova Marketa , Kyrou Ioannis

Introduction: Polycystic ovary syndrome (PCOS) is the most common endocrine disorder in women of reproductive age causing symptoms that can lead to depression and reduced health-related quality of life (HRQoL). Associations of depression and HRQoL indices with hormonal and metabolic PCOS features have not been adequately studied.Methods/design: Thirty-seven premenopausal women (age: 28±6.4 years; BMI: 28.3±7.2 kg/m2) with PCOS accord...

Interplay of NUCB2/Nesfatin-1 and inflammation in white adipose tissue

Gharanei Seley , Patel Vanlata , Shabir Kiran , Patel Ria , Randeva Harpal , Kyrou Ioannis

Background: Excess adipose tissue accumulation and obesity are characterised by a chronic, low-grade, systemic inflammation that contributes to obesity-related cardio-metabolic disease. Nestfatin-1 is a neuropeptide derived from the precursor protein nucleobindin-2 (NUCB2), which was initially reported to exert anorexigenic effects. We have previously shown that NUCB2/Nesfatin-1 is highly expressed in human and mouse subcutaneous white adipose tissue (Sc-WAT) and that circulat...

Asprosin exerts pro-inflammatory effects via the TLR4 pathway in THP-1 macrophages

Gharanei Seley , Shabir Kiran , Patel Vanlata , Brown James , Kyrou Ioannis , Randeva Harpal

Background: Adipose tissue exhibits an altered adipokine secretion profile in obesity which is pro-inflammatory and relates to higher risk of cardio-metabolic diseases. Asprosin is a novel pleiotropic adipokine with orexigenic and glucogenic effects which is secreted in response to fasting. Elevated circulating asprosin levels have been shown in obesity and type 2 diabetes, as well as in other cardio-metabolic diseases. Furthermore, in vitro studies have reported pro-...

A retrospective study assessing the effects of OSA in women with PCOS attending the weight management clinic

Kahal Hassan , Dimitriadis George K. , Kyrou Ioannis , Ali Asad , Tahrani Abd A , Randeva Harpal

Introduction: Obstructive Sleep Apnoea (OSA) is more common in women with Polycystic Ovary Syndrome (PCOS). There is paucity of data regarding the impact of OSA in women with PCOS.Methods: We conducted a retrospective study using electronic patientsÂ’ records of premenopausal women with PCOS who were first seen in the weight management clinic (WMC) between March/2008 and November/2014. PCOS diagnosis was documented either by referring clinician or es...

Altered mitochondrial dynamics in obesity: redressing the balance through bariatric surgery?

McCarthy Ciara , Voyias Philip , Antonysunil Adaikala , Harte Alison , Saravanan Ponnusamy , Kyrou Ioannis , Tripathi Gyanendra , McTernan Philip

Mitochondria are essential for synthesising ATP required for cellular metabolism. Mitochondria are able to alter their morphology and abundance through the balance of fission and fusion genes. T2DM is often accompanied by a metabolic syndrome within the individual. The aim of my PhD is to investigate whether metabolic dysregulation in T2DM can be linked to dysfunction within their mitochondria.Declaration of funding: EPSRC....

Melatonin ameliorates glucocorticoid-induced invasiveness and circadian rhythm disruption in human endometrial adenocarcinoma cells

Karapanagioti Angeliki , Nasiri-Ansari Narjes , Kyrou Ioannis , Mavrogianni Despoina , Drakakis Peter , kaltsas gregory , Papavassiliou Athanasios G. , Randeva Harpal , Kassi Eva

Introduction: The biological rhythm pattern is synchronized through circadian oscillation of cortisol and melatonin release. Increased cortisol levels and circadian rhythm disruption act as an oncogenic factor in endometrial cancer through among others- dysregulation of cell proliferation/apoptosis and invasion.Aim: To investigate, whether there is an oscillatory expression of the clock genes, MT1 and GR expression in human endometrial carcinoma cells. T...

Effects of the endocrine disrupting chemical bisphenol A (BPA) in human placentation in vitro

Greca Sophie-Christine de Aguiar , Kyrou Ioannis , Pink Ryan , Randeva Harpal , Grammatopoulos Dimitris , Silva Elisabete , Karteris Emmanouil

Endocrine disrupting chemicals (EDCs) are environmental chemicals/toxicants that humans and wildlife are exposed to and which interfere with the action of hormones. Bisphenol A (BPA) is classified as an EDC with xenoestrogenic activity and is recognized by the WHO as a chemical with potentially potent effects on humans throughout different phases of development. A significant knowledge gap still exists regarding the complete spectrum of BPA-induced effects on human physiology,...
