Reducing LDL Cholesterol is the Wrong Target for Cardiovascular Disease

When people say "cardiovascular disease" in the context of blood cholesterol, they mean atherosclerosis. This is the name given to the build up of fatty deposits that narrow and weaken blood vessels, leading to heart failure and ultimately some form of disabling or fatal rupture - a stroke or heart attack. The primary approach to treatment is the use of lifestyle choices and drugs such as statins to lower cholesterol carried by LDL particles in the blood. Unfortunately, the evidence strongly suggests that this is the wrong approach, in that the benefits are small and unreliable. Atherosclerosis does occur more readily with very high levels of LDL cholesterol, as illustrated by the early onset of the condition in patients with genetic disorders such as homozygous familial hypercholesterolemia, in which blood cholesterol can be as high as ten times normal. Yet reducing LDL cholesterol levels, even to as much as ten times lower than normal, does very little for patients with established atherosclerotic lesions. One has to look at the mechanisms of the disease in more detail to (a) see why this is the case, and (b) identify which classes of therapy should be attempted instead. Atherosclerosis is essentially a consequence of the failure of a process called reverse cholesterol transport. When cholesterol becomes stuck in excessive amounts in blood vessel walls, macrophage cells of the innate immune system are called to the site. The macrophages ingest choles...

In this study, we sought to elucidate the role of VRK-1 in regulation of adult life span in C. elegans. We found that overexpression of VRK-1::GFP (green fluorescent protein), which was detected in the nuclei of cells in multiple somatic tissues, including the intestine, increased life span. Conversely, genetic inhibition of vrk-1 decreased life span. We further showed that vrk-1 was essential for the increased life span of mitochondrial respiratory mutants. We demonstrated that VRK-1 was responsible for increasing the level of active and phosphorylated form of AMPK, thus promoting longevity. A Fisetin Variant, C...

CONCLUSION: Since there was no statistical significance between the probucol and control groups despite a marked reduction of HDL-C, further studies on the clinical outcomes of probucol on top of conventional therapy may be necessary in the future (UMIN000003307).

Obesity is a serious, chronic, treatable, and global disease epidemic. Over 98 million people currently have the disease of obesity, and in a recent New England Journal of Medicine article, Harvard researchers predicted that by 2030, 50% of the population in the United States will have the disease of obesity. Type 2 diabetes (T2D) is significantly associated with obesity. While many people with obesity do not have diabetes, most people with T2D have the disease of obesity. Excess adiposity (body fat storage), which is present in obesity, contributes to many chronic diseases beyond T2D. These include high blood pressure, he...

This study is par for the course, looking at Japanese Olympic participants. Interestingly, it hints at the upper end of the dose-response curve for physical activity, in that a longer career as a professional athlete may be detrimental in comparison to lesser degrees of exercise and training. From this large, retrospective cohort study targeting 3546 Japanese Olympic athletes, we observed significant lower mortality among Olympians compared with the Japanese general population. The overall standardised mortality ratio (SMR) was 0.29. The results were consistent with previous studies conducted in other non-Asian co...

Type 2 diabetes (T2D) is a metabolic disorder of insulin resistance — a reduced sensitivity to the action of insulin — which leads to high blood sugar, or hyperglycemia. Approximately 12% of American adults have T2D, and more than one-third of Americans have prediabetes, a precursor to T2D. This is a major public health concern, as T2D dramatically increases risk for heart disease, including heart attacks, atrial fibrillation, and heart failure. The development and progression of T2D is affected by many factors. Some, such as a person’s race/ethnicity, age, and gender cannot be modified. Others, including...

This study shows that CA are released from periventricular and subpial regions to the cerebrospinal fluid and are present in the cervical lymph nodes, into which cerebrospinal fluid drains through the meningeal lymphatic system. We also show that CA can be phagocytosed by macrophages. We conclude that CA can act as containers that remove waste products from the brain and may be involved in a mechanism that cleans the brain. Moreover, we postulate that CA may contribute in some autoimmune brain diseases, exporting brain substances that interact with the immune system, and hypothesize that CA may contain brain markers that m...

In conclusion, high-dose NR induces the onset of WAT dysfunction, which may in part explain the deterioration of metabolic health. Towards a Rigorous Definition of Cellular Senescence https://www.fightaging.org/archives/2019/11/towards-a-rigorous-definition-of-cellular-senescence/ The accumulation of lingering senescent cells is a significant cause of aging, disrupting tissue function and generating chronic inflammation throughout the body. Even while the first senolytic drugs capable of selectively destroying these cells already exist, and while a number of biotech companies are working on the productio...

In this study, researchers studied 438,952 participants in the UK Biobank, who had a total of 24,980 major coronary events - defined as the first occurrence of non-fatal heart attack, ischaemic stroke, or death due to coronary heart disease. They used an approach called Mendelian randomisation, which uses naturally occurring genetic differences to randomly divide the participants into groups, mimicking the effects of running a clinical trial. People with genes associated with lower blood pressure, lower LDL cholesterol, and a combination of both were put into different groups, and compared against those without thes...

We examined human lung tissue from COPD patients and normal control subjects, and found a substantial increase in p16-expressing alveolar cells in COPD patients. Using a transgenic mouse deficient for p16, we demonstrated that lungs of mice lacking p16 were structurally and functionally resistant to CS-induced emphysema due to activation of IGF1/Akt regenerative and protective signaling.
