## Resource

Cancer is not merely a genetic or metabolic disease, but a systematic remodeling of the mitochondrial network to drive malignancy. Tumors hijack fission, fusion, and transport mechanisms to power proliferation, metastasis, and drug resistance.

## Highlights
- Main idea: Cancer is a disease of mitochondrial network remodeling, not just static energy production
- Failure mode: Hyperactive fission (DRP1) and reduced fusion (MFN1/2) create fragmented networks that support tumor survival
- Practical takeaway: Targeting mitochondrial fission or fusion can disrupt tumor proliferation and invasion
- Complexity alert: The same mitochondrial mechanism can promote growth in one tumor type while driving resistance in another
- Future direction: Effective therapy will likely require strategic combinations of fission inhibitors and metabolic or immune modulators

## Topics

Mitochondrial Dynamics, Cancer Biology, Metastasis, DRP1, Drug Resistance, Metabolic Reprogramming, Precision Oncology, Cell Signaling

## Chapters
- 1:00 — The Shift to Mitochondrial Networks: Moving beyond the 'powerhouse' metaphor to view mitochondria as an active, dynamic network driving tumor behavior.
- 3:00 — Systematic Distortion in Cancer: How the balance of fission, fusion, and mitophagy is intentionally disrupted to support malignancy.
- 4:00 — The Role of DRP1 and Fission: The mechanics of DRP1-driven fission and its impact on mitochondrial fragmentation and cell survival.
- 6:00 — Morphology vs. Metabolic Function: How cancer cells maintain high oxidative metabolism despite a structurally fragmented mitochondrial network.
- 9:00 — Driving Proliferation and Apoptosis Resistance: How mitochondrial dynamics regulate cell division and help cancer cells bypass programmed cell death.
- 12:00 — Mitochondria as Tools for Metastasis: The strategic redistribution of mitochondria to the leading edge of cells to power migration and invasion.
- 14:00 — Drug Resistance and Immune Evasion: How mitochondrial remodeling enables resistance to chemotherapy and reshapes the immune microenvironment.
- 17:00 — Therapeutic Strategies and Precision Oncology: The potential for fission inhibitors and combination therapies, and the challenges of tumor heterogeneity.
