ROS Might Just Be A SideshowExploring Simultaneous Observation of mTORC1 Activity and Increase in ROS • Mohammad Farahmandnia • M.D. Undergraduate • Shiraz University of Medical Science • Shiraz, Iran
Definition of Aging • As tangible is senescence to human perception, it has proven hard to define. • Decline in the function of different organs of the body (Iseghohi 2016) • Hyperfunction (Blagosklonny 2008)
Diseases of Aging Farahmandnia 2016
Impact of Aging • 6 out of 10 major causes of death strongly correlated with aging and their share of deaths in 2012. (WHO Factsheets 2012) Farahmandnia 2016
Impact of Aging • When calculated cumulatively, 75% of deaths caused by major causes are to blame on diseases of aging. Farahmandnia 2016
Prominent Theories of Aging • Damage Accumulation • Reactive Oxygen Species-centeric • emphasizes decline of function • Wear and Tear • ~ Stem Cell-centric • emphasizes decline of function • Quasi-programmed • ~ mechanistic Target of Rapamycin-centric • emphasizes Hyperfunction
Getting to know mTOR • mTOR is the catalytic subunit of two distinct complexes called mTOR complex 1 (mTORC1) and mTORC2. Sabatini 2010

Agenda • Fruits Are Effective, But Not by Reducing ROS • Basic Science Evidence • Clinical Evidence • “What-the-hell” Evidence!
