Type:

APE1 - Apurinic/Apyrimidinic Endonuclease 1 / Redox Effector Factor 1

Abbreviation: APE1, APEX1, Ref-1

Type: DNA repair enzyme / redox regulatory protein

Function: Multifunctional protein that performs apurinic/apyrimidinic endonuclease activity in the base-excision repair (BER) pathway and also regulates the redox state and DNA-binding activity of transcription factors including NF-κB, HIF-1α, STAT3, and AP-1. APE1 supports DNA repair, oxidative-stress resistance, cell survival, angiogenesis, and transcriptional signaling.

Cancer: ↑ Frequently increased or activated in cancer. Elevated APE1/Ref-1 promotes DNA-damage repair, tumor-cell survival, proliferation, angiogenesis, and resistance to chemotherapy and radiotherapy. Inhibition of APE1 DNA-repair or redox activity can increase tumor-cell sensitivity to DNA-damaging therapies and suppress oncogenic transcription-factor signaling.

7311- Gos,    Systematic Review of Gossypol/AT-101 in Cancer Clinical Trials
- Review, CLL, NA
Dose↝, orally applied gossypol/AT-101 at low doses (30 mg daily or lower) was determined as well tolerable either as monotherapy or in combination with chemo-radiation.
toxicity↓,
PFS↓, Within these trials, a potential benefit was observed in high-risk patients or in some patients with prolongation in progression-free survival or in overall survival.
OS↑,
eff↑, most recent clinical trial combined low dose AT-101 with docetaxel, fluorouracil, and radiation, achieving complete responses in 11 of 13 patients with gastroesophageal carcinoma (median duration of 12 months) and a median progression-free survival o
BioAv↑, The gossypol (−)-enantiomer—also called AT-101—is degraded more slowly and is therefore the more biologically active form
Bcl-2↓, AT-101, a natural Bcl-2 homology domain 3 (BH3) mimetic, is a small molecule inhibitor that downregulates anti-apoptotic Bcl-2 and Bcl-2-related proteins in human cancer cells
ROS↑, In addition, gossypol-induced intrinsic apoptosis might occur also as reactive oxygen species (ROS)-independent
MOMP↑, In gossypol-treated cancer cells, alterations on the mitochondrial outer membrane permeabilization (MOMP) cause the release of large amounts of apoptotic markers, such as cytochrome c and apoptosis-inducing factor (AIF),
Dose↑, Thereby, the maximum tolerated gossypol dose was determined to be 0.8 mg/kg per day (50–60 mg/day),
Casp3↑, Gossypol-induced apoptosis appears to proceed via the caspase-dependent pathway by activation of caspase-3 and caspase-9
Casp9↑,
MMP↑, as well as mitochondrial membrane depolarization
VEGF↓, suppression of vascular endothelial growth factor (VEGF) stimulating intracellular pro-angiogenic kinases phosphorylation could be inhibited by AT-101
APE1/APEX1↓, addition of gossypol leads to inhibition of APE1 and enhances the activity of cisplatin in non-small cell lung cancer
ChemoSen↑,
RadioS↑, Moreover, AT-101 was demonstrated to radiosensitize prostate cancer in vitro and in vivo without augmenting toxicity
toxicity↑, hematologic toxicities are common treatment related toxicities
AST↑, he majority of related AEs were GI and nervous system disorders, increased AST/ALT, of grade 1/2 toxicities
ALAT↑,
