Methods: The tumor tissues of 78 LUAD and 56 LUSC patients who underwent surgery at The Second Affiliated Hospital of Zhengzhou University between October 2020 and October 2022 were collected, TIL level were detected by pathological observation, and the proportions of CD4+, CD4+ T cell subsets and CD4+/CD4+ ratio in TILs were detected by flow cytometry.

E3 ubiquitin ligase CHIP facilitates cAMP and cGMP signalling cross-talk by polyubiquitinating PDE9A.

The carboxyl terminus of Hsc70-interacting protein (CHIP) is pivotal for managing misfolded and aggregated proteins via chaperone networks and degradation pathways. In a preclinical rodent model of CHIP-related ataxia, we observed that CHIP mutations lead to increased levels of phosphodiesterase 9A (PDE9A), whose role in this context remains poorly understood. Here, we investigated the molecular mechanisms underlying the role of PDE9A in CHIP-related ataxia and demonstrated that CHIP binds to PDE9A, facilitating its polyubiquitination and autophagic degradation.
