Olfactory cells may act as 'Trojan horse,' carry anticancer therapy to deadly brain tumors

Researchers genetically engineered olfactory ensheathing cells to carry an anticancer drug, reducing tumor growth and improving survival in a mouse model. The treatment delivered the medication directly to glioblastoma cells while sparing healthy tissue, leading to a significant reduction in tumor size and prolonged survival.

Elephants resist cancer by waking a zombie gene

Researchers discovered elephants' ability to resist cancer stems from the 'zombie LIF6' gene, which kills cells poised to become cancerous. This strategy may inspire new treatments for humans by mimicking the gene's behavior or activating its existing copies.

Breaking through a tumor's defenses

Researchers identify dominant immune cells contributing to tumor tolerance and find that silencing these cells allows T cell attack on tumors. Jointly inhibiting both cell types substantially inhibits tumor growth in mouse models.

The role of cohesin in genome 3D structure helps for a better understanding of tumor cells

Scientists discovered that altered cohesin SA2 variant influences gene expression and favours loss of differentiation in tumour cells. The two cohesin variants have distinct functions, with SA1 involved in topological domains and SA2 regulating gene expression through local chromatin loops.

Elastic microspheres expand understanding of embryonic development and cancer cells

Researchers have developed a technique to quantify 3D forces within cells using elastic microspheres filled with fluorescent nanoparticles. The study found that these mechanical forces play a fundamental role in cell physiology and may help unlock mysteries related to embryonic development and cancer stem cells.

Water dynamics indicate tumor status

Researchers developed a method to measure proton nuclear resonance dispersion profiles at low magnetic fields, revealing the water exchange rate of tumor cells. This enables direct assessment of tumor status and metabolic activity, which is characteristic of aggressive and highly metastatic tumors.

Altered immune cells clear childhood brain tumor in mice

Researchers at Stanford Medicine have developed a CAR-T therapy that eradicates diffuse intrinsic pontine glioma (DIPG) tumors in mice, leaving few residual cancer cells. The treatment targets the GD2 sugar molecule on DIPG tumors and has shown promising results, but side effects such as brain swelling must be carefully managed.

Observing biological nanotransporters

Researchers shed light on functional mechanism of ABC exporters, which transport a wide range of molecules out of cells. This understanding could lead to new therapeutic approaches by specifically influencing or inhibiting these processes.

An index measures similarity between cancer cells and pluripotent stem cells

Researchers developed an index measuring similarity between cancer cells and pluripotent stem cells to predict tumor aggressiveness, treatment resistance, and clinical outcome. The index may help identify novel therapeutic targets against cancer by pinpointing the point at which tumor cells acquire stem cell-like characteristics.

Mathematical modeling offers new way to understand variable responses to targeted therapy

Researchers used a unique approach combining cell culture studies with mathematical modeling to determine how heterogeneity within a tumor and surrounding environment affect responses to targeted therapies. The study suggests that using a combination of drug inhibitors may be necessary to target diverse tumor cells.

Jekyll and Hyde and seek

A signaling protein called Daple, normally a tumor suppressor, can be manipulated by growth factors to become a driver of malignant growth and metastasis in cancer cells. This discovery highlights the complexity of crosstalk between major signals that drive cancers.
