CHK1 Inhibition in ER/PR-Defined Breast Cancer
2026-09-15
The reference study shows that CHK1 inhibition does not produce a uniform therapeutic response across breast cancer subtypes. Its main contribution is a receptor-context model in which CHK1 inhibition improves adriamycin sensitivity in ER−/PR−/HER2− disease but acts mainly as a single-agent strategy in ER+/PR+/HER2− cells.

cgSHAPE-seq Maps SARS-CoV-2 RNA-Degrader Binding
2026-09-15
The reference study introduces cgSHAPE-seq, a chemical-guided sequencing method that identifies where small molecules bind within structured RNA. Applied to the SARS-CoV-2 5′ untranslated region, the method located a primary SL5 binding site and supported optimization of an RNase L-recruiting RNA-degrading chimera that inhibited live-virus replication in lung epithelial carcinoma cells.

Norepinephrine Formulations in Critical Care Research
2026-09-14
The SCCM–ESICM position paper identifies a clinically important source of inconsistency: norepinephrine may be labeled as a conjugated salt, such as bitartrate or tartrate, or as norepinephrine base. Its central recommendation is to standardize reporting around norepinephrine-base equivalents so that bedside dosing, trial eligibility, and international datasets can be interpreted consistently.
