Rewiring the Molecular Interplay of CDK4/6 Inhibitors in Lung Cancer: From Cell Cycle Control to Immune Microenvironment Remodeling.
Review in International journal of molecular sciences, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Traditional inhibitors of cyclin-dependent kinases 4 and 6 (CDK4/6) have long been characterized as classical antiproliferative agents that induce G1 cell cycle arrest by blocking the phosphorylation of the retinoblastoma protein (Rb). However, recent studies in lung cancer have expanded this paradigm, revealing a functional transition from exclusive tumor suppression to the profound remodeling of the tumor microenvironment (TME) to enhance antitumor immunity. This review systematically outlines the genomic aberrations of the CDK4/6-Rb axis across lung cancer subtypes and dissects its immunomodulatory networks. These encompass the activation of effector T cells, the alleviation of immunosuppression mediated by regulatory T cells (Tregs), and the enhancement of antigen presentation via the Cyclic GMP-AMP synthase-stimulator of interferon genes (cGAS-STING) pathway. Furthermore, we analyze acquired resistance mechanisms, primarily focusing on p21-CDK2 bypass activation mediated by Cyclin E1 gene (
