Combinatorial treatment with PARP and MAPK inhibitors overcomes phenotype switch-driven drug resistance in advanced melanoma
Cancer Res. 2023 Sep 20. doi: 10.1158/0008-5472.CAN-23-0485. Online ahead of print.ABSTRACTMetastatic melanoma is either intrinsically resistant or rapidly acquires resistance to targeted therapy treatments, such as MAPK inhibitors. A leading cause of resistance to targeted therapy is a dynamic transition of melanoma cells from a proliferative to a highly invasive state, a phenomenon called phenotype switching. Mechanisms regulating phenotype switching represent potential targets for improving treatment of melanoma patients. Using a drug screen targeting chromatin regulators in patient-derived 3D MAPK inhibitor-resistant m...

NAT10 regulates the repair of UVB-induced DNA damage and tumorigenicity
Toxicol Appl Pharmacol. 2023 Sep 14:116688. doi: 10.1016/j.taap.2023.116688. Online ahead of print.ABSTRACTChemical modifications in messenger RNA (mRNA) regulate gene expression and play critical roles in stress responses and diseases. Recently we have shown that N6-methyladenosine (m6A), the most abundant mRNA modification, promotes the repair of UVB-induced DNA damage by regulating global genome nucleotide excision repair (GG-NER). However, the roles of other mRNA modifications in the UVB-induced damage response remain understudied. N4-acetylcytidine (ac4C) is deposited in mRNA by the RNA-binding acetyltransferase NAT10...

Comprehensive analysis of P2Y family genes expression, immune characteristics, and prognosis in pan-cancer
CONCLUSION: P2Ys may be used as potential pan-cancer biomarkers in prognosis and immunology. They may also be new targets for tumor immunotherapy, which has wide clinical implications.PMID:37672858 | DOI:10.1016/j.tranon.2023.101776

Radiation-sensitive genetic prognostic model identifies individuals at risk for radiation resistance in head and neck squamous cell carcinoma
CONCLUSIONS: Our prognostic model based on a radiation-related gene signature has potential for application as a tool for risk stratification of radiation therapy for patients with HNSCC, helping to identify candidates for radiation therapy and overcome radiation resistance.PMID:37656244 | DOI:10.1007/s00432-023-05304-x

Systematic review on gene-sun exposure interactions in skin cancer
CONCLUSION: Sun exposure seems to interact with genes involved in pigmentation, oxidative stress and immunosuppression, indicating that excessive UV exposure might exhaust oxidative defence and repair systems differentially, dependent on genetic make-up. Further research is warranted to better understand skin cancer epidemiology and develop sun exposure recommendations. A genome-wide approach is recommended as it might uncover unknown disease pathways dependent on UV radiation.PMID:37537768 | DOI:10.1002/mgg3.2259
