The hallmarks of cancer describe the fundamental biological capabilities that cancer cells acquire during the multistep development of human tumors. This influential framework was first introduced by Douglas Hanahan and Robert Weinberg in their landmark 2000 paper. It was significantly expanded in 2011 (“The Next Generation”), refined with new dimensions in 2022, and further updated in 2026 with Hanahan’s review “Hallmarks of Cancer—Then and Now, and Beyond”  ( Cell 2026 ,  Cell 2000 ,  Cell 2011 ,  AACR 2022 ). A thorough understanding of the problem is half the solution. In cancer biology, this principle highlights why the hallmarks framework remains so powerful: by clearly defining the core traits that allow cancer to develop, sustain itself, evade defenses, and spread, it offers a structured roadmap for decoding disease progression and uncovering targeted therapeutic strategies. Note: Cancer cells exhibit a distinct set of biological characteristics that set t...

Niclosamide was approved by FDA in 1982 for treating tapeworm infections, and was designated an essential drug by WHO. Niclosamide for Cancer Mechanisms: 1. Mitochondrial uncoupling - this is its major anti-cancer mechanism Niclosamide acts like a mild “leak” in the mitochondrial membrane, letting protons slip across without making ATP. This increases oxygen use, lowers ATP levels, raises AMP/ATP ratio & activates AMPK (energy sensor) to inhibit mTOR (slows down cancer cell growth). Cancer cells, which often rely on inefficient energy pathways (Warburg effect), are especially vulnerable. This can lead to inhibition of ATP synthesis, exhausting cellular energy reserves, metabolic stress, and cell death. 2. Signal pathway modulation - It inhibits several “pro-cancer” pathways, including: - Wnt/β-catenin (important in cancer proliferation, especially colorectal). - mTOR (controls cell proliferation, growth and metabolism). - Notch pathway (controls proliferation, growth, ...
