Mitochondria‐Targeting Abasic Site‐Reactive Probe (mTAP) Enables the Manipulation of Mitochondrial DNA Levels

Angewandte Chemie, EarlyView.
Mitochondria‐targeting water‐soluble probe mTAP exclusively reacts with mitochondrial abasic sites, enabling the manipulation of mitochondrial DNA levels under genotoxic stress. Abstract Mitochondrial DNA (mtDNA) encodes essential genes for mitochondrial and cellular functions and acts as a cell signaling molecule in innate immune and inflammatory ...

DNA Adducts with Lipid Peroxidation Products [PDF]

Journal of Biological Chemistry, 2008
Homolytic decomposition of PUFA2-derived lipid hydroperoxides results in formation of the α,β-unsaturated aldehydic bifunctional electrophiles DDE, EDE, HNE, HPNE, MDA (shown as β-hydroxyacrolein), ONE, DODE, and 5,8-dioxo-(10E)-octenoic acid (see Fig. 1) (1–3).

Structure and mechanism of human DNA polymerase η [PDF]

, 2010
The variant form of the human syndrome xeroderma pigmentosum (XPV) is caused by a deficiency in DNA polymerase eta (Pol eta), a DNA polymerase that enables replication through ultraviolet-induced pyrimidine dimers.

CD103+ T Cells Eliminate Damaged Alveolar Epithelial Type II Cells Under Oxidative Stress to Prevent Lung Tumorigenesis

Advanced Science, EarlyView.
This work unravels a novel function of CD103+ T cells in eradicating oxidative‐stressed somatic cells to prevent lung tumorigenesis and identifies specific CD103+ T cell‐decline as a key feature in the aged lung. This comprehensive study highlights the contribution of immuno‐dysregulation to the high incidence of aging‐associated lung cancers ...

Photosensitizer Repositioning Affords an Enantiocomplementary Enzyme for [2 + 2]‐Cycloadditions

Angewandte Chemie, EarlyView.
In this study, we capitalize on the versatility offered by genetic code expansion to develop a proficient photoenzyme for [2 + 2]‐cycloadditions that is enantiocomplementary to our recently developed photoenzyme EnT1.3. By repositioning the genetically programmed benzophenone photosensitizer and subsequent directed evolution, we have developed an ...

A Novel nor@DHB Matrix for Direct Microbial Analysis in Lung Cancer Tissues

Advanced Science, EarlyView.
Integrated matrix‐assisted laser desorption/ionization mass spectrometry workflow quantifies intratumoral microbes in lung cancer through lipopolysaccharide/lipid A extraction from biopsies. The novel ionic matrix called norharmane conjugated to 2,5‐dihydroxybenzoic acid enhances lipid A ionization, enabling direct detection of bacterial genera ...

Small Molecule‐Induced Alterations of Protein Polyubiquitination Revealed by Mass‐Spectrometric Ubiquitome Analysis

Angewandte Chemie, EarlyView.
To monitor small molecule‐induced changes in protein polyubiquitination in an unbiased manner, we employ enrichment through tandem ubiquitin binding entities coupled to LC‐MS/MS analysis (TUBE‐MS). By applying the workflow to PROTAC, p97‐ and deubiquitinase‐inhibitor treatment of cells, we demonstrate its broad applicability and reveal the induction of

Role of Topoisomerase IIβ in DNA Damage Response following IR and Etoposide

Journal of Nucleic Acids, 2010
The role of topoisomerase IIβ was investigated in cell lines exposed to two DNA damaging agents, ionising radiation (IR) or etoposide, a drug which acts on topoisomerase II. The appearance and resolution of γH2AX foci in murine embryonic fibroblast cell

Cadmium alters the formation of benzo[a]pyrene DNA adducts in the RPTEC/TERT1 human renal proximal tubule epithelial cell line

Toxicology Reports, 2014
Previously, we demonstrated the sensitivity of RPTEC/TERT1 cells, an immortalized human renal proximal tubule epithelial cell line, to two common environmental carcinogens, cadmium (Cd) and benzo[a]pyrene (B[a]P). Here, we measured BPDE-DNA adducts using
