Here, we performed unbiased genome-wide CRISPR/Cas9 knockout screens using endocrine sensitive ER+ breast cancer cells to identify novel drivers of resistance to combination endocrine therapy (tamoxifen) and CDK4/6 inhibitor (palbociclib) treatment. Our screens identified the inactivation of JNK signalling, including loss of the kinase MAP2K7, as a key driver of drug insensitivity. We developed multiple CRISPR/Cas9 knockout ER+ breast cancer cell lines (MCF-7 and T-47D) to investigate the effects of MAP2K7 and downstream MAPK8 and MAPK9 loss. MAP2K7 knockout increased metastatic burden in vivo and led to impaired JNK-mediated stress responses, as well as promoting cell survival and reducing senescence entry following endocrine therapy and CDK4/6 inhibitor treatment. Mechanistically, this occurred via loss of the AP-1 transcription factor c-JUN, leading to an attenuated response to combination endocrine therapy plus CDK4/6 inhibition. Furthermore, analysis of clinical datasets found that inactivation of the JNK pathway was associated with increased metastatic burden, and low pJNK<sup>T183/Y185</sup> activity correlated with a poorer response to systemic endocrine and CDK4/6 inhibitor therapies in both early-stage and metastatic ER+ breast cancer cohorts.

Recent investigations have clearly highlighted their involvement in cancer biology, particularly in the regulation of cancer metabolism. Unlike normal cells, cancer cells tend to favour the energy inefficient glycolytic pathway over the more effective oxidative phosphorylation process. TRP channels are involved in critical steps of cancer-related metabolic reprogramming by influencing intracellular Ca<sup>2+</sup> signaling. Their dysregulation can intensify oxidative stress, thereby promoting oncogenic transformation and tumor progression. The intricate interplay between TRP channels, metabolic reprogramming and oxidative stress promotes cancer cell progression and resistance to treatment. This review highlights the crucial role of TRP channels in tumorigenesis. It examines how TRPM7 and TRPM8 contribute to metabolic reprogramming by its involvement in glycolysis pathway. Additionally, it explores the involvement of TRPML1, TRPA1, TRPM2, and TRPV1 in modulating reactive oxygen species (ROS) levels within cancer cells, analyzing the ROS dual role in tumor modulation. The advent of nanotechnology, particularly through the utilisation of engineered nanoparticles, has facilitated the selective modulation of TRPA1, TRPM2, and TRPV1 channels.
