Course objectives
This course is focused on the hallmarks of aging in different organisms, with special emphasis on the molecular and cellular bases such as: deficiencies in DNA repair mechanisms in aged cells, mitochondrial dysfunction, telomere shortening, cellular senescence, alterations in epigenetic marks, loss of proteostasis, microbiome alterations, beneficial effects of dietary restriction in longevity etc. At the end we will discuss anti-aging medicine.
Learning outcomes
Students will be able to explain hallmarks of aging especially in human cells and also understand molecular mechanism of aging in various model organisms. Each chapter starts with a short overview of the discussed issue (e.g. repair mechanisms of DNA lesions, mitochondial or telomere functions, what is epigenetics and DNA / histone epigenetic modifications) followed by a closer description of the interconnection between the discussed topic and cellular aging. At the end students will be able to understand the mutual interconnection of discussed chapters.
