Cell division is crucial for the survival of living organisms. Human cells undergo three types cell division: mitosis, meiosis, and amitosis. The former two occur in somatic germ cells, respectively. Amitosis involves nuclear budding occurs that exhibit abnormal morphology (e.g., polyploidy) with increased size. In early 2000s, Kirsten Walen Rengaswami Rajaraman his associates independently reported polyploid human are capable producing progeny via amitotic division, a subset emerging daughter proliferate rapidly, stem cell-like properties, can contribute to tumorigenesis. Polyploid arise solid tumors/tumor-derived lines referred as giant cancer (PGCCs) known therapy resistance disease recurrence following anticancer treatment. This commentary provides an update on some these intriguing discoveries tribute Drs. Rajaraman.

What is apoptosis? The Nomenclature Committee on Cell Death and numerous other pioneering cancer/p53 biologists use the terms "apoptosis" "cell death" interchangeably, disregard mind-numbing complexity heterogeneity that exists within a tumor (intratumor heterogeneity), contribution of polyploid giant cancer cells (PGCCs; root causes therapy resistance relapse) to this heterogeneity, then propose novel apoptosis-stimulating anticancer strategies. This shocking for following three reasons. First, clinical studies reported since 1990s have revealed increased apoptosis in solid tumors associated with diversity poor prognosis. Second, we known years dying (apoptotic) release panel secretions (e.g., via phoenix rising pathways) promote metastatic outgrowth. Third, over decade ago, it was demonstrated can recover from late stages (after formation apoptotic bodies) homeostatic process anastasis, resulting emergence aggressive variants. cell surface expression CD24 has recently been be preferentially enriched recovered (anastatic) exhibit tumorigenic properties. These related discoveries outlined herein call paradigm shift oncology focus strategies minimize occurrence treacherous tumor-repopulating events therapy-induced dormancy reactivation). They also raise an intriguing question: deregulated anastasis (rather than evasion apoptosis) hallmark cancer?

Cancer therapy is facing increasingly significant challenges, marked by a wide range of techniques and research efforts centered around somatic mutations, precision oncology, the vast amount big data. Despite this abundance information, quest to cure cancer often seems more elusive, with “war on cancer” yet deliver definitive victory. A particularly pressing issue development tumor treatment resistance, highlighting urgent need for innovative approaches. Evolutionary, Quantum Biology System offer promising framework advancing experimental research. By integrating theoretical studies, translational methods, flexible multidisciplinary clinical research, there’s potential enhance current strategies improve outcomes patients. Establishing stronger links between evolutionary, quantum, entropy chaos principles oncology could lead effective treatments that leverage an understanding tumor’s evolutionary dynamics, paving way novel methods control mitigate cancer. Achieving these objectives necessitates commitment interprofessional collaboration at heart both endeavors in oncology. This entails dismantling silos disciplines, encouraging open communication data sharing, diverse viewpoints expertise from outset projects. Being receptive new scientific discoveries responsive how patients react also crucial. Such are key keeping field forefront management, ensuring receive most personalized care. Ultimately, approach aims push boundaries understanding, treating it as manageable chronic condition, aiming extend life expectancy patient quality life.

If one must prioritize among the vast array of contributing factors to cancer evolution, environmental-stress-mediated chromosome instability (CIN) should easily surpass individual gene mutations. CIN leads emergence genomically unstable life forms, enabling them grow dominantly within stable form host. In contrast, stochastic mutations play a role in aiding growth population, with their importance depending on initial new system. Furthermore, many specific available can perform this function, decreasing clinical value any mutation. Since these forms respond treatment differently than ones, often escapes from drug by forming systems, which problems during for patients. To understand how diverse impact CIN-mediated macroevolution and genome integrity–ensured microevolution, concept two-phased evolution is used reconcile some major characteristics cancer, such as bioenergetic, unicellular, multicellular evolution. Specifically, spiral function model proposed, integrates historical evolutionary innovations conservation information management. Unlike normal organismal microevolutionary phase, where given species occupies location spiral, populations are highly heterogenous at multiple levels, including epigenetic levels. Individual cells occupy different levels positions leading supersystems mixed cellular that exhibit both macro microevolution. This analysis, utilizing karyotype define genetic networks system determine system, well considering mutation epigenetics modifiers amplification usage, explores high potential cancer. It provides new, unified understanding supersystem, encouraging efforts leverage dynamics develop improved options. Moreover, it offers historically contingent reconciles roles innovation through respectively.
