FEBS Letters, EarlyView.Although too much iron in the brain promotes neurodegeneration, iron ion chelators have had mixed effects in clinical trials. This review explains why; some chelators do not render the iron redox‐inactive (e.g., L1) whereas others do (e.g., desferrioxamine).

An epithelial GPR35 isoform supports tumor‐associated transcriptional and metabolic phenotypes
FEBS Letters, EarlyView.GPR35 generates two functionally distinct isoforms with previously unresolved roles. GPR35‐short mediates immune‐cell chemotaxis, while GPR35‐long is enriched in colorectal cancer epithelium, where it supports increased metabolism, proliferation, and tumor‐associated transcriptional programs.

Nippon Shokuhin Kagaku Kogaku Kaishi, 2010 本研究では，AOAC Internationalの基準に基づき，代表的な抗酸化物質を用いて抗酸化能測定法であるH-ORAC法の室間共同試験を行い，精度の調査を行った．室間共同試験には5種（（＋）-カテキン，Trolox, trans-フェルラ酸，ヘスペレチン，コーヒー酸）の抗酸化物質溶液および粉末を用いた．その結果，RSDrは溶液試料で5.9～13.2％，粉末試料で5.4～10.4％であり，RSDRは溶液試料で16.2～61.4％，粉末試料で16.9～33.2％であった．Trolox検量線の上限濃度である50μMから算出したHorRat値は溶液試料で1.48～5.62，粉末試料で1.54～3.03であり，本室間共同試験によって妥当性が確認されたとは言い難かった．室間再現性低下の要因として ...

Tumour–host interactions in Drosophila: mechanisms in the tumour micro‐ and macroenvironment
Molecular Oncology, EarlyView.This review examines how tumour–host crosstalk takes place at multiple levels of biological organisation, from local cell competition and immune crosstalk to organism‐wide metabolic and physiological collapse. Here, we integrate findings from Drosophila melanogaster studies that reveal conserved mechanisms through which tumours hijack host systems to ...

Food Chemistry, 2014 The ORAC assay is applied to measure the antioxidant capacity of foods or dietary supplements. Sometimes, the manufacturers claim antioxidant capacities that may not correspond to the constituents of the product. These statements are sheltered by the general understanding that antioxidants might exhibit synergistic properties, but this is not ...

Molecular Oncology, EarlyView.The novel styrylquinazolinone‐based molecule W1B effectively suppresses glioblastoma by inhibiting IGF1R and EGFR. In high‐glucose microenvironments driving tumor resistance, W1B acts synergistically with the EGFR inhibitor dacomitinib. This combination safely blocks compensatory survival signaling in zebrafish xenograft models. Showcasing promising in
