Cellular senescence (CS) is recognized as a critical driver of aging and age-related disorders. Recent studies have emphasized the roles of ion channels as key mediators of CS. Nonetheless, the roles and regulatory mechanisms of chloride intracellular channels (CLICs) during CS remain largely unexplored.

The emergence of epidermal growth factor receptor tyrosine kinase inhibitors (EGFR-TKIs) has improved the prognosis for lung cancer patients with EGFR-driven mutations. However, acquired resistance to EGFR-TKIs poses a significant challenge to the treatment. Overcoming the resistance has primarily focused on developing next-generation targeted therapies based on the molecular mechanisms of resistance or inhibiting the activation of bypass pathways to suppress or reverse the resistance.

A series of Dehydroabietylamine (DHAA) C-ring Schiff derivatives, L3-L20, were synthesized and their in vitro cytotoxic activity against the human tumor cell lines cervix HeLa, breast MCF-7, lung A549, liver HepG2, and the nonmalignant cell line umbilical vein HUVEC was investigated. Most of the compounds showed varying degrees of anticancer activity against HeLa cell lines while demonstrating lower toxicity to normal HUVEC cells compared to DHAA and doxorubicin (DOX), especially compound L19, which not only enhanced the anticancer activity of DHAA, but also significantly reduced the toxicity to normal cells, achieving a selectivity index (SI) 118 times higher than that of DHAA and 245 times higher than that of DOX. In addition, compound L19 induced apoptosis in HeLa cells in a dose-dependent manner and arrested the cell cycle in S phase.

Developing effective nanoplatforms for chemo-immunotherapy to achieve enhanced tumor suppression and systemic antitumor immunity has recently received extensive attention. Herein, we formulated a multifunctional DNA sandwich nanodevice, DSWAC/siPD-L1, based on triangular DNA origami, to implement enhanced cancer chemo-immunotherapy. Taking advantage of the tumor-targeting ability of the AS1411 aptamer, DSWAC/siPD-L1 efficiently delivered doxorubicin (DOX), CpG, and siPD-L1 into tumor cells.
