Genotoxicity produced by disease and drugs

, 2009
In humans, DNA damage or genotoxicity may be caused by exposure to outsideagents like radiation, pesticides, combustion of hydrocarbons products as well asantineoplastic drugs.

MPP8 Facilitates DNA DSB Repair via NHEJ to Promote Chemoresistance of TNBC Independent of Methyl‐H3K9 Binding

Advanced Science, EarlyView.
Chemoresistance is often linked to elevated DNA repair. MPP8 is found to promote breast cancer chemoresistance as a novel NHEJ accessory factor independent of its epigenetic functions. Through multiple protein interactions, MPP8 facilitates association of DNAPK and ligase complexes to promote DNA repair progression.

Lactate‐H3K18la‐RPL11 Axis Drives Gemcitabine Resistance in Pancreatic Cancer by Integrating Protein Synthesis and DNA Damage Repair

Advanced Science, EarlyView.
A lactate‐H3K18la epigenetic axis upregulates RPL11 to drive gemcitabine resistance in pancreatic cancer. RPL11 orchestrates chemoresistance through a dual, compartmentalized role: enhancing cytoplasmic protein synthesis via EEF1A1 stabilization and promoting nuclear DNA damage repair by co‐activating PARP14, thus ensuring robust cell survival ...

A Biomimetic cRGDyk‐Engineered Platelet Nanoplatform for ACAD11 Delivery to Trigger Pyroptosis in Hepatocellular Carcinoma

Advanced Science, EarlyView.
A biomimetic platelet nanoplatform (OE‐ACAD11@R‐PLT) is developed for targeted hepatocellular carcinoma immunotherapy. By selectively delivering therapeutic plasmids, this system induces mitochondrial dysfunction and triggers robust NLRP3/Caspase‐1/GSDMD‐mediated pyroptosis in tumor cells.

Aged ZnO Nanoparticles Promote Breast Cancer Lung Metastasis by Remodeling the Pulmonary Microenvironment Through the CXCL10/Wnt/β‐Catenin Axis

Advanced Science, EarlyView.
In summary, pulmonary exposure to ZnO NPs, particularly aged NPs, promotes breast cancer metastasis by remodelling the lung tumour microenvironment. Aged ZnO NPs enrich M2‐macrophages, MDSCs and activated CAFs to form an immunosuppressive metastatic niche. CXCL10 from these cells drives metastasis via Wnt/β‐catenin activation.

Antigenotoxic Effect Of Ferulic Acid In 7,12-Dimethyl Benz(A)- Anthracene (Dmba) Induced Genotoxicity [PDF]

, 2008
The antigenotoxic effect of ferulic acid was carried out by evaluating the cytogenetic markers, the micronuclei frequency and chromosomal aberrations, in the bone marrow of hamsters in 7,12- dimethylbenz(a)anthracene (DMBA) induced genotoxicity ...

VCP‐Regulated LMF2 Stabilizes the Cholesterol Biosynthesis Enzyme HMGCS1 to Drive Cancer Progression and Confer Capecitabine Resistance in Triple‐Negative Breast Cancer

Advanced Science, EarlyView.
LMF2 drives progression and capecitabine resistance in triple‐negative breast cancer (TNBC). Mechanistically, VCP prevents NBR1‐mediated autophagic degradation of LMF2, thereby stabilizing it. Stabilized LMF2 subsequently suppresses NDP52‐mediated autophagic degradation of HMGCS1, a rate‐limiting cholesterol biosynthesis enzyme.

Tubocapsenolide A Overcomes Oxaliplatin Resistance in Colorectal Cancer by Targeting PLK1 to Impair CEP55–ESCRT‐Associated Vesicular Damage Clearance

Advanced Science, EarlyView.
Oxaliplatin‐resistant colorectal cancer cells utilize a previously unappreciated PLK1‐CEP55‐ESCRT‐driven vesicular extrusion mechanism to clear L‐OHP‐induced cellular damage. The natural withanolide Tubocapsenolide A directly targets and inhibits PLK1 to disrupt this specific damage‐clearance machinery. This blockade induces severe nucleolar stress and

The influence of organic solvents on estimates of genotoxicity and antigenotoxicity in the SOS chromotest

Genetics and Molecular Biology, 2012
In this work, the toxicity and genotoxicity of organic solvents (acetone, carbon tetrachloride, dichloromethane, dimethylsulfoxide, ethanol, ether and methanol) were studied using the SOS chromotest.
