The cellular response to hypoxia, primarily orchestrated by hypoxia-inducible factors (HIFs; mainly HIF-1α and HIF-2α), is at the center of several signaling pathways conferring aggressive tumor behavior. HIFs may be crucially involved in tumor initiation, as seen in clear cell renal cell carcinoma, as well as maintenance of resistance cancer stem cell phenotypes, as observed in glioma. In the fir
Hypoxia-inducible factors enhance glioma stemness, and glioma stem cells have an amplified hypoxic response despite residing within a perivascular niche. Still, little is known about differential HIF regulation in stem versus bulk glioma cells. We show that the intracellular domain of stem cell marker CD44 (CD44ICD) is released at hypoxia, binds HIF-2α (but not HIF-1α), enhances HIF target gene ac
Bärbara datorer och smarta telefoner har kommit att utmana arbetets traditionella gränser och bidragit till nya former att kombinera arbete med övrigt liv. När arbete sker på bekostnad av engagemang i den privata sfären, leder det ofta till upplevelser av stress och rollkon ikter, sk ”spillover”. ”Spillover” är en riskfaktor för hälsa och välbe nnande, men forskningen har ännu luckor för hur denna
For better or worse work plays a major role in both the psychological and thephysical well-being in peoples’ lives. Work can be a source of meaning, joy and self fulfilment, or a cause of distress and illness. This holds true even in wealthy parts ofthe world with a long tradition of research and governmental actions to achieve a goodworking environments. For example, in Sweden an average of 35 pe
Aim: The clinical significance of energy expenditure (EE) in the treatment of type 2 diabetes has not been fully elucidated. Here we analyzed the relationships between EE and clinical measurements in patients with type 2 diabetes receiving diet therapy. Methods: A total of 100 patients (34 women and 66 men) with type 2 diabetes admitted to our hospital for glycemic control were enrolled. The parti
The diagnostic steps for primary aldosteronism (PA) include case screening tests, confirmatory tests, and localization. The aim of this study was to identify useful confirmatory tests and their cut-off values for differentiating the subtype of primary aldosteronism, especially in unilateral PA, such as aldosterone-producing adenoma, and bilateral PA, such as idiopathic hyperaldosteronism. Seventy-
Mitochondrial diabetes mellitus (MDM) presenting with a mitochondrial DNA 3243 (A-G) mutation is most frequently observed in patients with diabetes caused by a genetic defect. Clinical manifestations include short stature, the absence of obesity, young-onset, and the maternal inheritance of diabetes. MDM is strongly associated with neurosensory deafness, which is often overlooked during routine me
The increase in the number of patients with diabetes has become a worldwide healthcare issue, with numbers predicted to reach approximately 600 million by 2035. In Asia-Pacific region, the prevalence of type 2 diabetes has increased dramatically in recent decades, of which the major causes are believed to be modern lifestyle changes, e.g., Western dietary pattern and reduced physical activity, on
We recently established 2 mouse lines with different susceptibilities (prone and resistant) to high-fat diet (HFD)-induced glucose intolerance by selective breeding (designated selectively bred diet-induced glucose intolerance-prone [SDG-P] and -resistant [SDG-R], respectively). In the present study, we analyzed transgenerational changes in metabolic phenotypes in these 2 mouse colonies to explore
Accumulation of phosphatidylcholine hydroperoxide (PCOOH), a primary oxidation product of phosphatidylcholine, in blood plasma has been observed in various pathological conditions, including atherosclerosis. In this study, we investigated the use of liquid chromatography-tandem mass spectrometry (LC-MS/MS) to develop a method for accurate quantification of PCOOH (1-palmitoyl-2-hydroperoxyoctadecad
Background: A number of epidemiological studies demonstrated that postprandial hyperglycemia is a risk factor for cardiovascular disease in individuals with impaired glucose tolerance. Although several laboratory studies have addressed the plausible causal role of postprandial acute hyperglycemia (glucose spikes) in the development of atherosclerosis, there is little convincing evidence in vivo wh
A 66-year-old man with type 2 diabetes on hemodialysis treatment was admitted due to poor glycemic control. His serum insulin level and the 125I-insulin binding rate were extremely high with an increased eosinophil count, although he did not have an allergic reaction to insulin or an elevation of specific IgE for human insulin. A Scatchard analysis revealed that the patient’s insulin antibodies ha
Aims/Introduction: α-Glucosidase inhibitors (αGIs) are widely used for the primary treatment of type 2 diabetes. We compared the clinical effects of three αGIs (miglitol, acarbose and voglibose) in patients with obese type 2 diabetes. Materials and Methods: Japanese patients (n = 81) with obese type 2 diabetes (body mass index [BMI] ≥25 kg/m2) were enrolled in this multicenter, open-label study. T
Hereditary predisposition to diet-induced type 2 diabetes has not yet been fully elucidated. We recently established 2 mouse lines with different susceptibilities (resistant and prone) to high-fat diet (HFD)-induced glucose intolerance by selective breeding (designated selectively bred diet-induced glucose intolerance-resistant [SDG-R] and -prone [SDG-P], respectively). To investigate the predispo
Aims/Introduction: Postprandial hyperglycemia is a potent risk factor for cardiovascular disease. Serum glycated albumin (GA) has been reported to reflect postprandial blood glucose fluctuations. In the present study, we assessed the possible correlation of GA with the presence of carotid plaque to evaluate the potential clinical usefulness of GA for predicting atherosclerotic cardiovascular compl
Objective: Impaired glucose tolerance (IGT) is an independent risk factor for atherosclerotic cardiovascular disease. However, due to the lack of appropriate animal models, the underlying mechanisms for IGT-induced atherosclerosis remain to be elucidated invivo. We recently used selective breeding to establish 2 mouse lines with distinctively different susceptibilities to diet-induced glucose into
Aims/Introduction: The development of type 2 diabetes is primarily due to lifestyle and environmental factors, as well as genetics, as shown by familial clustering. To establish mouse lines for evaluating heritable factors determining susceptibility to diet-induced diabetes, we performed selective breeding for differences in high fat diet (HFD)-induced glucose intolerance. Materials and Methods: S
A 76-year-old male was diagnosed to have diabetes mellitus at 57 years of age and oral hypoglycemic agents were started. Aspart, a human insulin analogue, was initiated because of a poor glycemic control in July 2009, at 74 years of age. He complained of dizziness and faintness caused by hypoglycemia in the early morning and afternoon. He was admitted to another hospital in August 2010; his plasma
