“Aging in tumor tissue is markedly accelerated, however – an indicator of the perturbed metabolic and growth processes observed in cancer. In this clip, Dr. Steve Horvath discusses correlations between epigenetic aging and age-related chronic diseases.”

“For example, Mendelian randomization studies, which provide evidence of links between modifiable risk factors and disease based on genetic variants within a population, have found that not only are some people genetically predisposed to engage in more physical activity, but they are also less likely to suffer from depression.”

“Dr. Patrick describes increased shear as a possible way vigorous exercise can damage fragile circulating tumor cells; this is a proposed mechanism, not proof that a workout eliminates metastasis or treats an established tumor.”

“Dr. Patrick also describes a proposed anti-metastatic mechanism: faster blood flow during vigorous exercise increases shear forces on circulating tumor cells, the cells that have left a primary tumor and entered the bloodstream.”

“In this excerpt from Dr. Rhonda Patrick’s A4M LongevityFest 2023 keynote, she reviews a randomized trial in sedentary middle-aged adults. Two years of progressive, supervised aerobic training increased VO2 max and reduced left-ventricular stiffness.”

“Controlled human studies support acute brain-related responses to high-intensity exercise. Six short all-out cycling intervals improved selected learning and executive measures while increasing circulating BDNF, IGF-1, and VEGF; lactate tracked several of these changes.”

“Mounting evidence suggests that exploiting this property may be useful towards reducing the toxicity of chemotherapeutics while also maximizing their impact in the treatment of cancer.”

“An emerging strategy in the prevention and (possibly) treatment of neurodegenerative diseases is starving cells as a means to induce general autophagy to help rid the cell of protein aggregates.”

“When produced during exercise (especially high intensity workouts like cycling, which shifts metabolism toward glycolysis to more quickly meet the high energetic demands), lactate switches on more than 600 genes involved in muscle adaptation, stimulates mitochondrial biogenesis – the process of making new mitochondria – and promotes protein synthesis, which is essential for muscle growth.”

“Dr. Rhonda Patrick talks at SF Nerd Nite about transgenerational effects of caloric restriction on longevity, B-vitamins silencing bad genes, cognitive stimulation reversing neurodegenerative disease, exercise increases neurogenesis, and ways in which vitamin D might influence aging.”
