Downregulation of MUTYH contributes to cisplatin ‑resistance of esophageal squamous cell carcinoma cells by promoting Twist‑mediated EMT.
In conclusion, the present data demonstrated that EMT activation mediated by MUTYH downregulation, by both enhancing Twist transcription and blocking its degradation, is one of the mechanisms for acquisition of CDDP resistance in ESCC. PMID: 31578574 [PubMed - as supplied by publisher]

Auranofin, an Anti-rheumatic Gold Drug, Aggravates the Radiation-Induced Acute Intestinal Injury in Mice
Conclusion In this study, we found that a non-toxic dose of auranofin significantly aggravated the severity of the radiation-induced intestinal injury. This suggests that auranofin treatment can be an independent factor that influences the risk of intestinal complications after pelvic or abdominal radiotherapy. Ethics Statement All the protocols used in this study were approved by the Institutional Animal Care and Use Committee of the Korean Institute of Radiological and Medical Sciences (IACUC permit number: KIRAMS217-0007). Author Contributions H-JL, JS, and Y-BL designed the experiments. EL and JK conducted the exp...

Abstract 493: NRF2 modulates sensitivity to thymidylate synthase inhibitors in colon cancer cells
Thymidylate synthase (TYMS) catalyzes the reductive methylation of dUMP, and is the sole de novo source of thymidine for DNA replication and repair. As such, it is an important target of chemotherapeutic drugs, particularly the fluoropyrimidines 5-fluorouracil (FUra) and 5-fluoro-2’-deoxyuridine (FdUrd), as well as the folate analog raltitrexed (RTX). In cells, these drugs are metabolized to derivatives that bind to and inhibit TYMS, leading to depletion of thymidine levels, dysregulation of redox metabolism, generation of oxidative stress, and, eventually, apoptotic cell death. Gene expression profiles of FUra-treated H...

Secreted protein acidic and rich in cysteine (SPARC) is upregulated by transforming growth factor (TGF)-ß and is required for TGF-ß-induced hydrogen peroxide production in fibroblasts
Conclusions: The results presented in this study suggest that SPARC plays a role in epithelial damage in the IPF lung via enhanced H2O2 production from fibroblasts activated by TGF-β. Therefore, SPARC inhibition may prevent epithelial injury in IPF lung and represent a potential therapeutic approach for IPF.
