Calcium channel blockers potentiate gemcitabine chemotherapy  in pancreatic cancer

Abstract: Significance Pancreatic cancer is a leading cause of cancer-related death, in part due to incomplete responses to standard-of-care chemotherapy. In this study, using a combination of single-cell RNA sequencing and high-throughput proteomics, we identified the calcium-responsive protein calmodulin as a key mediator of resistance to the first-line chemotherapy agent gemcitabine. Inhibition of calmodulin led to the loss of gemcitabine resistance in vitro, which was recapitulated using a calcium chelator… Show more

“…Several existing chemotherapeutic agents such as cisplatin, can modify intracellular Ca 2+ , prompting tumor cell apoptosis [ 42 ]. Furthermore, the calcium signaling pathway significantly contributes to drug resistance in tumors [ 43 ]. Consequently, proteins that regulate Ca 2+ such as transmembrane cation channels, hold promise as potential targets for cancer treatment.…”

“…In a retrospective cohort study, the authors concluded that CCBs may prolong survival in PC patients [30]. Principe et al (2022) [31] used CCBs, such as amlodipine, which inhibited pro-survival extracellular signal-regulated kinase (ERK) signaling in vitro and remarkably enhanced therapeutic responses to gemcitabine in both orthotopic xenografts and transgenic PC models. Further prospective studies are required to establish the exact impact of anti-hypertensive treatment on PC patient survival.…”

“…In contrast, our experiments with gemcitabine are in line with the role of TRPV6 as a Ca 2+ channel. Gemcitabine toxicity is activated by the blockage of calmodulin pathways [36]. The knockdown of TRPV6 can lead to lower levels of calmodulin activation and thereby increase the cytotoxicity of gemcitabine action in PDAC cells [27].…”
