Tumor cells
Tumor cells are the malignant cellular component of a cancerous tumor.
Tumor cells are the malignant cellular component of a cancerous tumor. They arise from genetic and epigenetic alterations that disrupt normal control of proliferation, survival, differentiation, and interaction with the surrounding tumor microenvironment. As a result, tumor cells can acquire properties such as unchecked growth, resistance to apoptosis, immune evasion, invasive behavior, and drug resistance. Their biology is strongly shaped by signals from the tumor microenvironment, including cytokines, metabolic stress, and interactions with stromal cells, immune cells, and extracellular matrix.
In biomedical research, tumor cells are a central therapeutic target for chemotherapy, photochemotherapy, photothermal therapy, immunotherapy, and nanomedicine-based drug delivery. Many recent studies have focused on selectively directing agents to tumor cells, reversing chemoresistance, or inducing immunogenic cell death and cytotoxicity. In these contexts, pathways involving transforming growth factor, reactive oxygen species, glutathione metabolism, and immune checkpoints can influence how tumor cells respond to treatment and how effectively the tumor can be controlled.

Where the papers sit
21 papers study tumor cells directly. Those 21 are one subject: Cancer Therapeutic Strategies. Targeted delivery is being paired with chemotherapy, immunotherapy, photothermal or sonodynamic treatment, often to induce ferroptosis or reverse resistance. UBC9 and PI3K expression adds a prognostic dimension. No way of splitting those 21 scores better than chance.

Cancer Therapeutic Strategies: Iron-deprivation liposomes, biomimetic nanoparticles, extracellular vesicles, nanogels, and bacteria-activated nanozymes improve delivery to tumor cells 42711711Sep42486784Jul42474418Jul42229647Jun42053349Apr42170851May. These platforms combine chemotherapy with ferroptosis, apoptosis, photothermal therapy, sonodynamic therapy, chemodynamic therapy, or cuproptosis 42711711Sep42402299Jul42315000Jun42295973Jun42474418Jul. Several strategies reverse resistance by silencing MGMT, remodeling M2-like tumor-associated macrophages, blocking CAF-driven pyrimidine metabolism, or reducing oxidative-stress defenses 42315000Jun42486784Jul42202065May42170851May41936879Apr. Immune-directed approaches enhance treatment through immunogenic cell death, dendritic cell maturation, CD8-positive T-cell infiltration, engineered CAR-T cells, TIGIT-edited NK cells, and ACE-iMac macrophages 42486097Jul42619089Aug41916312Mar41982126Apr41968179Apr. UBC9 and PI3K co-expression marks poor prognosis and chemoresistance in colorectal cancer, whereas exercise scheduling produces a different result: higher frequency reduced tumor suppression when total exercise volume remained fixed 42522541Jul42049052Apr.
