Osteosarcoma (OS), a malignant bone tumor with limited treatment options, exhibits low sensitivity to immune checkpoint therapy (ICT). Through genomics and transcriptomics analyses, we have identified a subgroup of OS with methylthioadenosine phosphorylase (MTAP) deletion, which contributes to ICT r...

RESTRICTION checkpoint controls bradyzoite development in Toxoplasma gondii
Mitochondrial homeostasis of endocrine organ navigates nutrient restriction checkpoint
Analysis of effect of S-phase arrest and replication checkpoint activation on differentiating hESCs at the gene expression level. The hypothesis tested in the present study was that replication checkpoint activation prevents the exit from pluripotency in hESCs. Results provide important information ...

The Toxoplasma gondii G1 RESTRICTION checkpoint operates the switch between parasite growth and differentiation. The Cdk-related G1 kinase TgCrk2 forms alternative complexes with atypical cyclins (TgCycP1, TgCycP2 and TgCyc5) in the rapidly dividing developmentally incompetent RH and slower dividing...

Although apicomplexans lack conventional R-point regulators, presence of the quiescent G1 forms of 43 parasites, including mature T. gondii bradyzoites suggests that a functional RESTRICTION checkpoint 44 exists in apicomplexan parasites. We showed that Cdk-related G1 kinase TgCrk2 forms alternative...

Steroid hormones are powerful endocrine regulators, but little is known about the integration of their production with environmental conditions. Here, we use Drosophila prothoracic gland (PG) to examine how insect steroid hormone production navigates a developmental checkpoint critical for juvenile-...
