Paeoniflorin is a monoterpenoid glycoside found in the roots of <i>Paeonia lactiflora Pall</i> and has been reported to have a variety of health benefits. However, the mechanisms underlying its therapeutic effects on high glucose (HG)-induced oxidative damage in RPE cells are not fully understood. In this study, we investigated the protective effect of paeoniflorin against HG-induced oxidative damage in cultured human RPE ARPE-19 cells, an <i>in vitro</i> model of hyperglycemia. Pretreatment with paeoniflorin markedly reduced HG-induced cytotoxicity and DNA damage. Paeoniflorin inhibited HG-induced apoptosis by suppressing activation of the caspase cascade, and this suppression was associated with the blockade of cytochrome c release to cytoplasm by maintaining mitochondrial membrane stability. In addition, paeoniflorin suppressed the HG-induced production of reactive oxygen species (ROS), increased the phosphorylation of nuclear factor erythroid 2-related factor 2 (Nrf2), a key redox regulator, and the expression of its downstream factor heme oxygenase-1 (HO-1). On the other hand, zinc protoporphyrin (ZnPP), an inhibitor of HO-1, abolished the protective effect of paeoniflorin against ROS production in HG-treated cells. Furthermore, ZnPP reversed the protective effects of paeoniflorin against HG-induced cellular damage and induced mitochondrial damage, DNA injury, and apoptosis in paeoniflorin-treated cells. These results suggest that paeoniflorin protects RPE cells from HG-mediated oxidative stress-induced cytotoxicity by activating Nrf2/HO-1 signaling and highlight the potential therapeutic use of paeoniflorin to improve the symptoms of DR.</p>","PeriodicalId":8949,"journal":{"name":"Biomolecules & Therapeutics","volume":"33 3","pages":"518-528"},"PeriodicalIF":3.0,"publicationDate":"2025-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12059356/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143966923","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Cynaropicrin-induced cytotoxicity and cytoplasmic vacuolation, a key characteristic of paraptosis, were not ameliorated by inhibitors of necroptosis, autophagy, or pan caspase inhibitors in Hep3B cells.

Recent advances in targeting DNA damage response (DDR) pathways using poly (ADP‒ribose) polymerase (PARP) inhibitors offer promising therapeutic strategies, especially for TNBC patients with BRCA1/2 mutations. This study reports the development and characterization of ART-446, a novel and selective CHK2 inhibitor. ART-446 showed potent activity against TNBC, regardless of BRCA deficiency, and it also reversed PARP inhibitor resistance. ART-446 potently inhibited CHK2 (IC<sub>50</sub>: 9.06 nM) with high selectivity over other kinases; it synergized with the PARP inhibitor olaparib, enhancing DNA damage, inducing G2/M cell cycle arrest, and promoting apoptosis in both BRCA-mutant and wild-type TNBC cells. Mechanistic analyses revealed that ART-446 sensitized BRCA mutant and WT cells to PARP inhibitors by impairing DNA repair and increasing the accumulation of DNA damage. Importantly, ART-446 disrupted both homologous recombination and nonhomologous end-joining repair pathways, addressing a key limitation of PARP inhibitor monotherapy-resistance in BRCA-proficient cancers. <i>In vivo</i>, the combination of ART-446 and olaparib significantly reduced tumor growth in TNBC xenograft models without noticeable toxicity. The combined treatment increased DNA damage signaling, as evidenced by elevated γH2AX levels, and enhanced the sensitivity of BRCA2-deficient cells to ART-446. These findings underscore the potential of ART-446 to exploit DNA repair deficiencies and overcome resistance mechanisms associated with PARP inhibitors.

Targeting apoptosis of ovarian cancer and angiogenesis is promising for anticancer therapy. Leaves of <i>Ipomoea</i> sp. have reportedly shown promise in treating ovarian cancer. Here, we investigated the apoptosis-inducing and anti-angiogenic effects of compounds isolated from <i>Ipomoea batatas</i> vines (IBV). Phytochemical examination of IBV led to the isolation and verification of eight compounds (<b>1-8</b>): chlorogenic acid (<b>1</b>), 3,4-dicaffeoylquinic acid (<b>2</b>), 3,5-dicaffeoylquinic acid (<b>3</b>), 4,5-dicaffeoylquinic acid (<b>4</b>), 1,3,5-tricaffeoylquinic acid (<b>5</b>), <i>N-trans</i>-feruloyltyramine (<b>6</b>), scopoletin (<b>7</b>), and esculetin (<b>8</b>). Of these, 1,3,5-tricaffeoylquinic acid (5) showed the highest cytotoxicity in A2780 human ovarian cancer cells, inducing apoptotic death in more than 37% cells and decreasing viability to less than 25% at 100 μM. Compound <b>5</b> increased the levels of cleaved caspase-8, Bax, cleaved PARP, and caspase-3/9, and decreased the levels of cleaved Bcl-2. Further, <b>5</b> inhibited tubule formation in HUVECs. VEGFR2, ERK, PI3K, Akt, and mTOR protein expression was also suppressed by <b>5</b>. Then, a simple, rapid, and reliable LC-MS/ MS method was developed to determine the contents of the isolated compounds from IBV. Overall, <b>5</b> has potential for treating ovarian cancer as it induces apoptosis in ovarian cancer cells and inhibits tube formation.</p>","PeriodicalId":8949,"journal":{"name":"Biomolecules & Therapeutics","volume":" ","pages":"483-493"},"PeriodicalIF":3.0,"publicationDate":"2025-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12059361/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143802280","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
