Abstract
Cancer immunotherapies have revolutionized cancer treatment, yet many patients fail to respond. Activating innate immunity offers a promising approach to enhance therapeutic efficacy, but the signaling kinases directly regulating this process to boost antitumor responses remain elusive. Here we conduct an in vivo kinome CRISPR screen and identify CDK10 as a key suppressor of tumor immune surveillance. Mechanistically, CDK10 phosphorylates DNMT1 and RAP80 to reduce the accumulation of double-stranded RNA and R-loops, which alleviates the activation of innate immune pathways mediated by MDA5 and cGAS. Kinase inhibitor screens identify NVP-AST487 and ponatinib as selective CDK10 inhibitors. Both genetic and pharmacological inhibition of CDK10 activates MDA5 and cGAS pathways, fostering an immunoactive tumor microenvironment that enhances cancer immunotherapy in multiple mouse tumor models. Clinically, low CDK10 expression in tumors correlates with better immunotherapy responses. These findings establish CDK10 as a pivotal modulator of tumor immunity and a potential therapeutic target.

Schematic model of CDK10-mediated regulation of tumor immunity. CDK10 plays a critical role in suppressing the accumulation of dsRNA and R-loops by phosphorylating DNMT1 and RAP80. This phosphorylation prevents the activation of the MDA5 and cGAS-STING innate immune pathways. Consequently, genetic or pharmacological inhibition of CDK10 triggers the activation of both the MDA5 and cGAS-STING pathways, thereby enhancing antitumor immunity and improving the efficacy of immune-checkpoint blockade (ICB) therapy. Data are represented as mean ± SEM, for a, c and j, analyzed by two-way ANOVA with Tukey’s multiple-comparisons test; for b, d–h, analyzed by one-way ANOVA with Tukey’s multiple-comparisons test. For k, Kaplan–Meier survival analysis and two-tailed Gehan–Breslow-Wilcoxon test were performed.
