Etiology of atherosclerosis informs choice of animal models and tissues for initial functional genomic studies of resveratrol

Publication date: Available online 14 February 2020Source: Pharmacological ResearchAuthor(s): Lukasz Huminiecki, Atanas G. Atanasov, Jarosław HorbańczukAbstractResveratrol, a phytoalexin, is a natural polyphenol synthesized exclusively by plants in response to environmental stresses. However, the molecule has also many exogenous bioactivities in animal cells. These bioactivities may lead to anti-cancer and cardio-protective health benefits. Because cellular responses to the treatment with resveratrol include the changes of expression patterns, functional genomics is an attractive tool to study them. In recent and today’s experimental practice, this mostly means microarray profiling of gene expression (using RNAs isolated from bulk tissues). Herein, we review such published studies undertaken in the context of cardiovascular diseases (CVDs). CVDs are a number one public health problem in developed countries, outweighing in magnitude even cancer. In particular, we review the studies of resveratrol in several animal models relevant to CVDs. These models included: normal and pre-mature aging in mice, as well as atherogenic diet in mice / pigs / non-human primates. Additionally, there were few clinical studies published in the context of the comorbidities of atherosclerosis in humans (e.g. obesity, diabetes, hypertension). For the purposes of these studies, three types of samples were most commonly profiled with microarrays: the liver, the skeletal muscle, and peripheral b...

Unhealthy food habits are associated with non-communicable diseases (NCD) [1 –3] and nutritional deficiencies [4]. According to the World Health Organization (WHO) [5], more than half of all deaths were due to ten main causes, with the leading killers being ischaemic heart disease and stroke. Diets characterized by a low intake of fruit and vegetable (FV) and fibre increas e the risk of hypertension, diabetes mellitus (DM), obesity, cardiovascular diseases (CVD), gastrointestinal cancers, nutritional deficiencies, pancreatic diseases, depression and the development of cognitive impairment and dementia [4–7].

Abstract Coronary heart disease kills twice as many women as breast cancer in the UK and is the single biggest killer of women worldwide. Underlying risk factors include hypertension, diabetes, hyperlipidaemia, obesity and smoking. Mulder and colleagues have performed a systematic review and meta-analysis of the literature and demonstrated that women with infertility are significantly more likely to have certain cardiometabolic risk factors, namely increased BMI, cholesterol and triglycerides, when compared with fertile women.

This study was not perfect. You could argue, as these authors do, that the fact that participants chose their preferred diet is a good thing, as it could theoretically improve adherence. However, it also resulted in very different-sized groups to start with. The varying adherence and exercise option choices were adjusted for as well as possible. And the study relied heavily on self-reporting, which is always iffy. Healthy eating patterns have benefits beyond weight loss But we can still learn a great deal here. The Mediterranean approach to eating (which can be easily modified to suit any country or cultural food preferenc...

r M Abstract Obesity contributes to reduced life expectancy, impaired quality of life and disabilities mainly in those individuals who develop cardiovascular diseases, type 2 diabetes, osteoarthritis and cancer. However, there is large variation in the individual risk to develop obesity-associated comorbid diseases which cannot simply be explained by the extent of adiposity. Observations that a proportion of individuals with obesity have a significantly lower risk for cardiometabolic abnormalities led to the concept of metabolically healthy obesity (MHO). Although there is no clear definition, normal glucose and l...

gel Ferro Overweight and obesity are among the most prominent health problems in the modern world, mostly because they are either associated with or increase the risk of other diseases such as type 2 diabetes, hypertension, and/or cancer. Most professional organizations define overweight and obesity according to individual body–mass index (BMI, weight in kilograms divided by height squared in meters). Overweight is defined as individuals with BMI from 25 to 29, and obesity as individuals with BMI ≥30. Obesity is the result of genetic, behavioral, environmental, physiological, social, and cultural fa...

Telomerase gene therapy is considered in some quarters to be a viable treatment for aging. Telomeres are the caps of repeated DNA sequences at the ends of chromosomes. They are an important part of the mechanism limiting the number of times that somatic cells in the body can divide, the Hayflick limit. A little telomere length is lost with each cell division, and short telomeres trigger cellular senescence or programmed cell death, halting replication. Stem cell populations use telomerase to lengthen their telomeres and thus self-renew to provide a continual supply of new somatic daughter cells with long telomeres to repla...

No, I kid you not. There’s no Sir Not-Appearing-in-this-Film nor eloquent monologues about swallows, and not even a reference to hose-riding coconut mimicry. I’ve truly found the Holy Grail of health tracking and will share it with you today. Behold as the answer is… the smart sleep alarm! If you ask anyone I know, they’ll probably share how I reverently praise smart sleep alarms. By the end of this article, you will understand why this is the case.

By ALYA AHMAD, MD Call it what you want, white privilege and health disparity appear to be two sides of the same coin. We used to consider ethnic or genetic variants as risk factors, prognostic to health conditions. However, the social determinants of health (SDOH) have increasingly become more relevant as causes of disease prevalence and complexity in health care. As a pediatric hospitalist in the San Joaquin Valley region, I encounter these social determinants daily. They were particularly evident as I treated a 12-year old Hispanic boy who was admitted with a ruptured appendix and developed a complicated abscess,...
