Chemical probes and their correct use are essential for accurate and robust data. Here, authors show that only 4% of analyzed publications used chemical probes in line with recommendations. This indicates that the best practice with chemical probes is yet to be implemented in research.

Progesterone (P₄) signalling is involved in physiological control of the endometrium and contributes to the pathogenesis of endometrial diseases such as endometriosis. Here the authors report that CFP1, a regulator of histone methylation, controls endometrial responses to P₄ and lack of endometrial CFP1 leads to failure of embryo implantation and exacerbated experimental endometriosis in mice.

Understanding dosage-sensitive processes requires quantitative modulation of protein abundance. Here the authors report a CRISPR-based methodology for analog tuning of endogenous gene expression, CasTuner, and show homogeneous gene expression tuning across mouse and human cells.
