The NLRP3 Inflammasome Inhibitor OLT1177 Rescues Cognitive Impairment in a Mouse Model of Alzheimer’s Disease

Scientists analyzed the effect of pharmacological inhibition of the nucleotide-binding oligomerization domain-like receptor family, pyrin domain containing 3 (NLRP3) inflammasome using dapansutrile (OLT1177), an oral NLRP3-specific inhibitor that is safe in humans.

The ZNF750–RAC1 Axis as Potential Prognostic Factor for Breast Cancer

Reseachers showed that ZNF750 negatively regulates cell migration and invasion in breast cancer cells; in particular, ZNF750 binds and recruits KDM1A and HDAC1 on the LAMB3 and CTNNAL1 promoters.

Histone H3.3G34-Mutant Interneuron Progenitors Co-Opt PDGFRA for Gliomagenesis

The authors showed that 50% of glycine 34 to arginine/valine (G34R/V) tumors bore activating PDGFRA mutations that displayed strong selection pressure at recurrence. G34R/V tumors arise in GSX2/ DLX-expressing interneuron progenitors, where G34R/V mutations impair neuronal differentiation.

CCL7 Recruits cDC1 to Promote Antitumor Immunity and Facilitate Checkpoint Immunotherapy to Non-Small Cell Lung Cancer

Researchers demonstrated that CCL7 facilitates anti-PD-1 therapy for the KrasLSL−G12D/+Tp53fl/fl and the KrasLSL−G12D/+Lkb1fl/fl non-small cell lung cancer mouse models by recruiting conventional DC 1 (cDC1) into the tumor microenvironment to promote T cell expansion.

Scientists showed that protein levels of the Bromodomain and extra-terminal domain (BET) protein BRD4 were significantly increased in the muscle of the mouse model of Duchenne muscular dystrophy, the mdx mouse, and that pharmacological inhibition of the BET proteins had a beneficial outcome, tempering oxidative stress and muscle damage.
