Introduction: The Challenge of Cancer Cell Immortality
Cancer, a leading cause of death worldwide, remains a formidable challenge largely due to the unique ability of cancer cells to evade the natural limits of cellular life. Unlike normal cells, which have a built-in “expiration date,” cancer cells find ways to become virtually immortal, continuously dividing and growing unchecked. This limitless proliferation is underpinned by mechanisms that preserve the integrity of chromosome ends, known as telomeres. Traditional cancer treatments have largely focused on protein targets, but a pioneering Israeli research team has developed a revolutionary approach that targets RNA molecules controlling this immortality at a more fundamental level.
