Triple negative breast cancer (TNBC) is aggressive and lacks specific receptors, making it hard to treat, with paclitaxel being a common anticancer drug used.
In a study with TNBC cells, a small number of cells survived after treatment with paclitaxel, leading to the emergence of a new highly proliferative and tumorigenic cell line called MDA-MB-231-JYJ.
These new cells showed resistance to dasatinib, a drug inhibiting certain cancer pathways, suggesting that patients undergoing treatment may develop resistance, highlighting the need for careful clinical trial designs involving these agents.
* Research involved inducing P19 embryonal carcinoma cells to become neuron-like cells, and during this process, they expressed both NgR1 and NMDA receptors, indicating they retained some neural characteristics.
* The study suggests that these neuronally differentiated P19 cells could be a useful in vitro model for exploring how NgR1 and its associated pathways work, as well as testing potential drugs that could influence NgR1 activity.
