Refining Tumor Mutational Burden as a Predictive Biomarker for Pembrolizumab: A Real‐World Analysis in Japanese Patients

Cancer Science, Volume 117, Issue 4, Page 1158-1166, April 2026.
In this study, we investigated the predictive value of tumor mutational burden (TMB) for assessing the efficacy of pembrolizumab in a Japanese cohort. We analyzed real‐world data from 63,952 patients registered in the C‐CAT database who underwent comprehensive genomic profiling, and evaluated the therapeutic efficacy of pembrolizumab in 1899 of these ...

Target capture efficiently resolves the long‐standing taxonomic dead end of Diachrysia moths

Systematic Entomology, Volume 51, Issue 2, April‐June 2026.
We demonstrate the high efficiency of the target capture method in elucidating the taxonomy of the cryptic species of Diachrysia chrysitis and D. stenochrysis. Phylogenomic and population structure analyses reveal clear nuclear divergence and asymmetric allele sharing, consistent with historical gene flow rather than recent hybridization.
