MOMP Cancer Research Results

MOMP, Mitochondrial Outer Membrane Permeabilization: Click to Expand ⟱
Source:
Type:
MOMP is the point-of-no-return decision step of intrinsic apoptosis. It is the event in which the mitochondrial outer membrane becomes permeable, allowing release of pro-death factors that irreversibly commit a cell to die. Cancer progression is characterized by systematic suppression, buffering, or decoupling of MOMP from lethal execution.

MOMP occurs when BAX and/or BAK oligomerize in the mitochondrial outer membrane, forming pores that release:
-Cytochrome c → apoptosome → caspase-9
-Smac/DIABLO → IAP neutralization
-Other apoptogenic factors (e.g., Omi/HtrA2)
Once sufficient mitochondria undergo MOMP, cell death is inevitable (even if caspases are later inhibited).
Redox, Metabolism, and MOMP (Critical)
-High xCT / GSH → suppress mitochondrial ROS → MOMP ↓
-Autophagic flux → removes damaged mitochondria → MOMP ↓
-Pro-oxidant overload → mitochondrial dysfunction → MOMP ↑

5519- EP,    Nanosecond Pulsed Electric Fields (nsPEFs) for Precision Intracellular Oncotherapy: Recent Advances and Emerging Directions
- Review, Var, NA
MMP↓, nsPEF bypasses plasma-membrane shielding to porate organelles, collapse mitochondrial potential, perturb ER calcium, and transiently open the nuclear envelope.
Ca+2↑,
eff↑, synergy with checkpoint blockade.
ER Stress↑, capacity to directly target organelles such as mitochondria, endoplasmic reticulum (ER),
selectivity↑, selectively ablate solid tumors, suppress metastatic spread, and prime systemic anti-tumor immunity while sparing adjacent normal tissue [7,9,10,11,12,13,14,15].
CSCs↓, Preclinical investigations have demonstrated that nsPEFs significantly reduce CSC-associated subpopulations, including CD44+/CD24− cells in breast cancer xenografts and CD133+ glioma stem-like cells
CD44↓,
CD133↓,
ROS↑, nsPEFs release Ca2+ from the ER, disrupt mitochondrial membrane potential, induce reactive oxygen species (ROS) generation, and perturb nuclear chromatin structure within nanoseconds

DNAdam↑, figure 2
MOMP↑, induce mitochondrial outer membrane permeabilization (MOMP)
Cyt‑c↑,
Casp9↑, Subsequent release of cytochrome c enables apoptosome assembly, caspase-9 activation, and downstream activation of caspases-3/7, culminating in cell death
Casp3↑,
Casp9↑,
TumCD↑,
Fas↑, In certain cell types, nsEP can also activate the extrinsic pathway, where Fas receptor clustering stimulates caspase-8.
UPR↑, This rapid surge triggers ER stress pathways, activates unfolded protein response (UPR) signaling, and promotes cross-talk with mitochondria through mitochondria-associated membranes (MAMs)
Dose↝, longer ns pulses (100–300 ns) generate sustained plasma membrane charging, resulting in robust Ca2+ influx, osmotic imbalance, and apoptotic priming.
Dose↝, A critical threshold of 10–20 kV/cm is generally required to initiate pore formation in malignant cells, with higher amplitudes (>30–40 kV/cm) producing more extensive permeabilization [100].
Dose↓, Low pulse counts (<100) frequently produce reversible stress responses, such as transient mitochondrial depolarization or ER Ca2+ release, without committing cells to apoptosis. I
Dose↑, In contrast, higher pulse counts (500–1000) lead to irreversible apoptosis, caspase activation, and release of DAMPs that initiate ICD [80,106].
HMGB1↓, ICD after nsPEF is characterized by surface exposure of calreticulin, extracellular ATP release, and HMGB1 emission
eff↑, The integration of nsPEFs with NP-based systems thus represents a synergistic platform where physical membrane poration and molecular targeting cooperate to maximize therapeutic efficacy.
EPR↑, demonstrates that PEF + AuNPs enhanced membrane permeabilization compared with PEF alone,
ChemoSen↑, The superior efficacy of delayed drug administration following nsPEF exposure can be attributed to transient biophysical and biochemical changes that persist after pulsing.
ETC↝, study demonstrated that nsPEFs dynamically alter trans-plasma membrane electron transport (tPMET) and mitochondrial electron transport chain activity, resulting in differential ROS generation in cancer versus non-cancer cells (Figure 9).
*AntiAge↑, Mechanistically, nsPEFs upregulated HIF-1α and SIRT1, mediators of mitochondrial retrograde signaling, thereby reversing hallmarks of aging
