In parallel, studies focusing on the tumor microenvironment have revealed critical insights into the role of senescent macrophages in KRAS-driven lung cancer. The clearance of these macrophages was shown to ameliorate tumorigenesis, suggesting that targeting the senescence-associated secretory phenotype (SASP) could be a viable therapeutic strategy (ref: Haston doi.org/10.1016/j.ccell.2023.05.004/). Moreover, methionine restriction has been identified as a mechanism to enhance antitumor immunity through the activation of cyclic GMP-AMP synthase (cGAS), which plays a pivotal role in immune response (ref: Fang doi.org/10.1016/j.ccell.2023.05.005/). The integration of these findings underscores the importance of understanding both intrinsic cellular mechanisms and the broader tumor microenvironment in developing effective cancer therapies.
