Apoptosis
Apoptosis is a regulated form of cell death that removes unwanted, damaged, or potentially harmful cells while generally limiting the inflammatory response associated with uncontrolled cell lysis.
Apoptosis is a regulated form of cell death that removes unwanted, damaged, or potentially harmful cells while generally limiting the inflammatory response associated with uncontrolled cell lysis. It is biologically important for tissue homeostasis and is also a major target in disease research, particularly in cancer, where impaired apoptotic signaling can support abnormal cell survival and proliferation.
Apoptotic signaling is commonly assessed through changes in the balance between pro- and anti-apoptotic regulators such as BCL2 Associated X, Apoptosis Regulator (BAX) and BCL2 apoptosis regulator, activation of caspases including Caspase-3 (CASP3), caspase-7, caspase-8, and caspase-9, and cleavage of substrates such as poly(ADP-ribose) polymerase (PARP). The recent literature represented here places apoptosis within the broader theme of Cell Death in Disease, linking mitochondrial dysfunction, reactive oxygen species, oxidative stress, endoplasmic-reticulum stress, autophagy, DNA damage, and immune responses. These studies examine both induction of apoptosis for cancer treatment and suppression of apoptosis to protect tissues such as the brain and heart.

BCL2 Pathway Apoptosis
BAX, BCL2, CASP3 and PARP1 recur as markers and mediators of apoptosis across diverse experimental treatments. Natural products, purine analogues and daunorubicin-loaded silica nanoparticles are being explored to activate this intrinsic death pathway or improve drug delivery. Autophagy, oxidative stress and carboplatin sensitization broaden the mechanisms beyond a single pathway. Evidence remains mainly preclinical, with uncertain clinical relevance and tissue selectivity.

Stress-Induced Tissue Apoptosis
Oxidative, endoplasmic-reticulum and mitochondrial stress are repeatedly connected to BAX-regulated apoptosis in injured tissues. Electroacupuncture, kaempferol-functionalized selenium nanoparticles and plant-derived treatments aim to reduce apoptosis alongside inflammation or organ damage. The studies emphasize protective effects in brain, stomach and heart models, while computational work seeks broader regulators of programmed cell death. Whether these approaches translate into reliable disease-modifying therapies remains open.

Immune-Activating Cancer Cell Death
Cancer cell killing is being linked to immune activation rather than treated as apoptosis alone. Carbon ion irradiation drives necroptosis and systemic immunity, while engineered Salmonella combines apoptin-mediated death with immune effects. Ruthenium compounds add mitochondria-mediated apoptosis, especially in melanoma models. The main open question is whether these distinct death programs can produce durable antitumor immunity in patients.
