Lactate dehydrogenase (LDH-A and LDH-B) |
↓ LDH activity |
Warburg glycolysis inhibition |
Galloflavin directly inhibits both isoforms of LDH, blocking the conversion of pyruvate to lactate and impairing glycolytic flux in tumor cells. :contentReference[oaicite:1]{index=1} |

Glycolysis output / ATP synthesis |
↓ lactate production & ATP |
Reduced cancer cell energy |
Galloflavin blocks aerobic glycolysis in multiple tumor cell lines, reducing lactate and ATP, and thus limiting energy available for proliferation. :contentReference[oaicite:2]{index=2} |

| 3 |
Cell proliferation |
↓ proliferation / growth |
Growth suppression |
Galloflavin inhibits proliferation across several cancer cell models (breast cancer MCF-7, MDA-MB-231, and tamoxifen-resistant cells), independent of glycolytic phenotype. :contentReference[oaicite:3]{index=3} |

| 4 |
Apoptosis induction |
↑ apoptosis (caspase activation) |
Programmed cell death |
Breast cancer work shows galloflavin induces apoptosis as the main mode of cell death, with signaling differences depending on glycolytic status. :contentReference[oaicite:4]{index=4} |

| 5 |
Reactive oxygen species (ROS) |
↑ ROS |
Oxidative stress |
Endometrial cancer cells treated with galloflavin show increased ROS production, potentially contributing to cytotoxicity and DNA damage. :contentReference[oaicite:5]{index=5} |

| 6 |
Mitochondrial apoptosis axis (Bcl-2/MCL-1 changes) |
↑ mitochondrial apoptosis |
Execution-phase cell death |
In endometrial cancer cells, galloflavin increases markers of mitochondrial apoptosis (e.g., cleaved caspase-3) while lowering anti-apoptotic proteins Bcl-2 and Mcl-1. :contentReference[oaicite:6]{index=6} |

Cell cycle regulation |
↑ cell-cycle arrest |
Proliferation blockade |
GF induces cell-cycle changes in endometrial cancer models (e.g., G2 arrest in some lines), indicating impacts on proliferation checkpoints. :contentReference[oaicite:7]{index=7} |

| 8 |
Metastasis-related markers (E-cadherin / Slug) |
↑ E-cadherin / ↓ Slug |
Reduced invasive phenotype |
Galloflavin treatment increases E-cadherin and decreases Slug in endometrial cancer cells, consistent with reduced migratory/invasive capacity. :contentReference[oaicite:8]{index=8} |

LDH-A binding to ssDNA & RNA synthesis |
↓ LDH-A-ssDNA binding & ↓ RNA synthesis |
Transcription/stress axis |
Galloflavin prevents LDHA binding to single-stranded DNA and inhibits RNA synthesis independently of glycolysis. :contentReference[oaicite:9]{index=9} |

Combinatorial metabolic inhibition (in vitro) |
↑ metabolic stress when combined |
Enhanced anti-proliferative effect |
In vitro work shows galloflavin enhances antiproliferative and apoptotic effects in combination with other metabolic inhibitors (e.g., CPI-613) in pancreatic cancer cells. :contentReference[oaicite:10]{index=10} |
