A structured walk through the core molecular pathways that govern energy, growth, redox balance, inflammation, and longevity.
The Cell Code walks through each cellular pathway in turn: what it does, how it's regulated, how it goes wrong in disease, and the drugs and lifestyle changes that shift it. Each pathway closes with foundational and advanced questions to test your understanding.
Learn what each of the ten core pathways actually does and the signals that switch it on, from AMPK and mTOR to the sirtuins, NRF2, NF-κB, and FOXO.
See how the pathways interact to balance energy, growth, redox, and inflammation, working as one connected system rather than ten separate switches.
Use each pathway's mechanism to reason through real clinical problems in aging, metabolic disease, neurodegeneration, and longevity.
Every pathway ends with twenty questions, ten foundational and ten advanced, each with an explanation of the correct answer and why the others are wrong.
Ten molecular pathways, thirty guided lessons, and two hundred questions with full explainers: the complete cellular-medicine foundation, taught mechanism-first.
The master energy sensor that switches on when fuel runs low to drive fatty-acid oxidation, glucose uptake, mitochondrial biogenesis, and autophagy, and it puts the brakes on mTOR.
The growth switch that decides whether cells build or recycle. Chronic overactivity drives aging, cancer, and metabolic disease; dialing it down extends lifespan across species.
Seven NAD⁺-dependent deacetylases (SIRT1–7) that couple energy status to DNA repair, stress resistance, and mitochondrial health, plus the longevity benefits of fasting and exercise.
The nutrient-and-growth axis through PI3K/AKT, central to glucose handling, protein synthesis, and survival, and the most reproducible genetic lever on lifespan.
Held in check by KEAP1 and released by oxidative stress to switch on 200+ genes for antioxidant defense, detoxification, and ferroptosis protection.
The master regulator of inflammation and inflamm-aging, balancing protective immunity against the chronic, self-amplifying inflammation that drives age-related disease.
The coactivator that builds new mitochondria and powers fatty-acid oxidation and antioxidant defense, switched on downstream of AMPK and SIRT1.
The quality-control cycle of fission, fusion, and PINK1/Parkin mitophagy that keeps the mitochondrial network healthy and clears damaged organelles.
Reactive oxygen species as both damaging agents and precise signaling molecules: the eustress-versus-distress balance, and why blanket antioxidants fail in trials.
Stress-sensing transcription factors behind antioxidant defense, DNA repair, and autophagy, and one of only two genes consistently tied to human longevity.
