Near infrared-assisted Fenton reaction for tumor-specific and mitochondrial DNA-targeted photochemotherapy
The strong dependence on oxygen level, low ultraviolet/visible (UV/vis) light penetration depth and the extremely short lifetime of reactive oxygen species (ROS) are the major challenges of photodynamic therapy (PDT) for tumors. Fenton reaction can produce abundant ROS such as reactive hydroxyl radi...

| 520 | |a The strong dependence on oxygen level, low ultraviolet/visible (UV/vis) light penetration depth and the extremely short lifetime of reactive oxygen species (ROS) are the major challenges of photodynamic therapy (PDT) for tumors. Fenton reaction can produce abundant ROS such as reactive hydroxyl radicals ( OH) with significantly higher oxidation performance than singlet oxygen (1O2), which, however, has been rarely used in biomedical fields due to strict reaction conditions (favorably in pH range of 3–4, mostly under UV/vis light catalysis). Herein we propose and demonstrate a photochemotherapy (PCT) strategy of cancer therapy using near-infrared (NIR)-assisted tumor-specific Fenton reactions. NIR light-upconverted UV/vis light by upconversion nanoparticles (UCNPs) catalyze the intra-mitochondrial Fenton reaction between the delivered Fe2+ and H2O2 species over-expressed in cancer cell's mitochondria to in-situ kill the cancer cells. The intra-mitochondrial ROS generation of enabled by directly targeting the mitochondrial DNA (mtDNA) helix minimized the distance between the ROS and mtDNA molecules, thus the present PCT strategy showed much enhanced and tumor-specific therapeutic efficacy, as demonstrated by the intratumoral-accelerated OH burst and elevated cytotoxicity. Following the direct intratumoral injection, the PCT revealed marked tumor regression effect in vivo. This constructed PCT-agent is the first paradigm of NIR-upconversion catalyzed intra-mitochondrial Fenton reaction in response to tumoral microenvironment, establishing a novel photochemotherapy strategy for efficient cancer therapy. | ||

The strong dependence on oxygen level, low ultraviolet/visible (UV/vis) light penetration depth and the extremely short lifetime of reactive oxygen species (ROS) are the major challenges of photodynamic therapy (PDT) for tumors. Fenton reaction can produce abundant ROS such as reactive hydroxyl radicals ( OH) with significantly higher oxidation performance than singlet oxygen (1O2), which, however, has been rarely used in biomedical fields due to strict reaction conditions (favorably in pH range of 3–4, mostly under UV/vis light catalysis). Herein we propose and demonstrate a photochemotherapy (PCT) strategy of cancer therapy using near-infrared (NIR)-assisted tumor-specific Fenton reactions. NIR light-upconverted UV/vis light by upconversion nanoparticles (UCNPs) catalyze the intra-mitochondrial Fenton reaction between the delivered Fe2+ and H2O2 species over-expressed in cancer cell's mitochondria to in-situ kill the cancer cells. The intra-mitochondrial ROS generation of enabled by directly targeting the mitochondrial DNA (mtDNA) helix minimized the distance between the ROS and mtDNA molecules, thus the present PCT strategy showed much enhanced and tumor-specific therapeutic efficacy, as demonstrated by the intratumoral-accelerated OH burst and elevated cytotoxicity. Following the direct intratumoral injection, the PCT revealed marked tumor regression effect in vivo.

The intra-mitochondrial ROS generation of enabled by directly targeting the mitochondrial DNA (mtDNA) helix minimized the distance between the ROS and mtDNA molecules, thus the present PCT strategy showed much enhanced and tumor-specific therapeutic efficacy, as demonstrated by the intratumoral-accelerated OH burst and elevated cytotoxicity. Following the direct intratumoral injection, the PCT revealed marked tumor regression effect in vivo. This constructed PCT-agent is the first paradigm of NIR-upconversion catalyzed intra-mitochondrial Fenton reaction in response to tumoral microenvironment, establishing a novel photochemotherapy strategy for efficient cancer therapy.</subfield></datafield><datafield tag="650" ind1=" " ind2="7"><subfield code="a">Fenton reaction</subfield><subfield code="2">Elsevier</subfield></datafield><datafield tag="650" ind1=" " ind2="7"><subfield code="a">Mitochondrial DNA</subfield><subfield code="2">Elsevier</subfield></datafield><datafield tag="650" ind1=" " ind2="7"><subfield code="a">Photochemotherapy</subfield><subfield code="2">Elsevier</subfield></datafield><datafield tag="650" ind1=" " ind2="7"><subfield code="a">Near infrared</subfield><subfield code="2">Elsevier</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Wu, Tong</subfield><subfield code="4">oth</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Fan, Wenpei</subfield><subfield code="4">oth</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Chen, Lei</subfield><subfield code="4">oth</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Liu, Yanyan</subfield><subfield code="4">oth</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Ni, Dalong</subfield><subfield code="4">oth</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Bu, Wenbo</subfield><subfield code="4">oth</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Shi, Jianlin</subfield><subfield code="4">oth</subfield></datafield><datafield tag="773" ind1="0" ind2="8"><subfield code="i">Enthalten in</subfield><subfield code="n">Elsevier Science</subfield><subfield code="t">Lymphotoxin in the Pathogenesis of Autoimmune Pancreatitis: A New Player in the Field</subfield><subfield code="d">2012</subfield><subfield code="d">biomaterials reviews online</subfield><subfield code="g">Amsterdam [u.a.]</subfield><subfield code="w">(DE-627)ELV011266368</subfield></datafield><datafield tag="773" ind1="1" ind2="8"><subfield code="g">volume:141</subfield><subfield code="g">year:2017</subfield><subfield code="g">pages:86-95</subfield><subfield code="g">extent:10</subfield></datafield><datafield tag="856" ind1="4" ind2="0"><subfield code="u">https://doi.org/10.1016/j.biomaterials.2017.06.035</subfield><subfield code="3">Volltext</subfield></datafield><datafield tag="912" ind1=" " ind2=" "><subfield code="a">GBV_USEFLAG_U</subfield></datafield><datafield tag="912" ind1=" " ind2=" "><subfield code="a">GBV_ELV</subfield></datafield><datafield tag="912" ind1=" " ind2=" "><subfield code="a">SYSFLAG_U</subfield></datafield><datafield tag="912" ind1=" " ind2=" "><subfield code="a">FID-BIODIV</subfield></datafield><datafield tag="912" ind1=" " ind2=" "><subfield code="a">SSG-OLC-PHA</subfield></datafield><datafield tag="936" ind1="b" ind2="k"><subfield code="a">35.70</subfield><subfield code="j">Biochemie: Allgemeines</subfield><subfield code="q">VZ</subfield></datafield><datafield tag="936" ind1="b" ind2="k"><subfield code="a">42.12</subfield><subfield code="j">Biophysik</subfield><subfield code="q">VZ</subfield></datafield><datafield tag="936" ind1="b" ind2="k"><subfield code="a">42.15</subfield><subfield code="j">Zellbiologie</subfield><subfield code="q">VZ</subfield></datafield><datafield tag="951" ind1=" " ind2=" "><subfield code="a">AR</subfield></datafield><datafield tag="952" ind1=" " ind2=" "><subfield code="d">141</subfield><subfield code="j">2017</subfield><subfield code="h">86-95</subfield><subfield code="g">10</subfield></datafield><datafield tag="953" ind1=" " ind2=" "><subfield code="2">045F</subfield><subfield code="a">570</subfield></datafield></record></collection>
