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 ↑

- Review, BC, NA
BioAv↓, However, its poor water solubility limits its optimal therapeutic potential.
BioAv↑, nano-drug delivery systems (NDDSs) have gained significant attention as a method to substantially improve low solubility and poor drug bioavailability, enhance targeted drug delivery, and reduce side effects.
selectivity↑, reviews by Simone Fulda23,24 strengthened BA's potential for cancer treatment and prevention, particularly its ability to selectively trigger apoptosis in cancer cells while causing minimal harm to normal cells.
eff↑, It is important to note that the anticancer effects of BA on different types of tumors are more potent at a pH lower than 6.8.34

MMP↓, BA-induced mitochondrial depolarization
Bcl-2↓, BA treatment has been shown to lower Bcl-2 expression and increase Bax, resulting in the activation of caspase-9 and caspase-3 through the mitochondrial pathway.63
BAX↑,

ChemoSen↑, BA's ability to chemosensitize BC cells to taxanes highlights its importance in situations of drug resistance
SESN2↑, Under hypoxia, BA strongly increases SESN2 expression.
ROS↑, Reducing SESN2 levels enhances BA-induced ROS production, DNA damage, and radiosensitivity, while decreasing autophagic flux, indicating that SESN2-mediated autophagy serves as a protective adaptive response.68
MOMP↓, decreases the mitochondrial outer membrane potential (MOMP),
MAPK↑, This leads to the activation of p38 Mitogen-activated protein kinase (p38 MAPK), the release of cytochrome C, apoptosis-inducing factor (AIF),
Cyt‑c↑,
AIF↑,
STAT3↓, BA suppresses the signal transducer and activator of transcription (STAT) 3 signaling pathways
FAK↓, BA's inhibition of STAT3, as well as FAK, leads to decreased expression of MMPs and elevated TIMP-2, thereby impairing cancer cell migration and invasion
TIMP2↑,
TumCMig↓,
TumCI↓,
Sp1/3/4↓, Sp inhibition reduces cancer gene expression, inhibiting cancer cell growth.
TumCCA↑, It increases cell numbers in the G2/M phase, leading to cell cycle arrest.
DNAdam↑, causes DNA damage, thereby inhibiting the progression and invasion of cancer cells.
