qPCR Quantification of Moloney Murine Leukemia Virus
2026-09-22
Choi, Murphy, and Nitta developed a real-time PCR assay that targets a packaging signal–gag region to quantify exogenous Moloney murine leukemia virus while reducing interference from endogenous retroviral sequences. The method detected viral sequences in infected mouse cells across a 16–72-hour post-infection window and provides a faster, scalable molecular complement to focal immunofluorescence assays.

Thioredoxin Control of CHK1 Inhibitor Sensitivity
2026-09-22
The reference study identifies the thioredoxin system as a determinant of CHK1 inhibitor response in non-small cell lung cancer. Its central advance is linking Trx1-dependent redox recycling of RRM1 to ribonucleotide reductase activity, deoxynucleotide availability, replication stress, and the therapeutic synergy between CHK1 and thioredoxin reductase inhibition.

Clathrin-Mediated Entry of Type III GCRV
2026-09-16
Wang et al. combined inhibitor profiling, transmission electron microscopy, and quantitative PCR to show that genotype III grass carp reovirus enters CIK cells through a dynamin-dependent, acidification-sensitive clathrin pathway. IPA-3 did not measurably inhibit infection in this model, providing a useful negative pharmacological comparator rather than evidence that Pak1 drives viral entry.
