Nanoparticles, nanoshells, nanotubes: How tiny specks may provide powerful tools against cancer

...l cost-effective way to diagnose whether cells are cancerous or not in a matter of minutes versus hour or days ...ost-effective and could diagnose whether cells are cancerous or not in a matter of minutes versus hours or days with current methods of histology sectioning," sa...

Double trouble: Cells with duplicate genomes can trigger tumors

...ormal cells that might make the tetraploid-derived cancerous cells vulnerable to doses of drugs that aren't harmful to the normal cells and tissues. " In other experiments, we identified genes in a model organism-- yeast-- that are essential for the survival of tetraploid cells but not for cells with a normal ...

Polymer gel can block toxic leakage problem in gene therapy

... have plagued attempts to use gene therapy against cancerous tumors. The problem has been that viruses carrying anti-tumor genes have tended to leak from tumors, proving toxic to other body tissues. The researchers have developed a biocompatible polymer that briefly changes from a liquid at 39 degrees Fahrenh...

University of Delaware researchers develop cancer 'nanobomb'

...east cancer cells, because its shockwave kills the cancerous cells as well as the biological pathways that carry instructions to generate additional cancerous cells and the small veins that nourish the diseased cells. Also, it can be spread over a wide area t...

Mechanism for Epstein-Barr virus protein's role in blood cancers discovered

...ransform human B cells from the immune system into cancerous cells, which can lead to B-cell lymphomas. Now, they have found that the viral protein--called EBNA3C (for EBV nuclear antigen)--mediates the degradation of the retinoblastoma protein, an important molecular brake for cell proliferation.

Embryonic stem cells accrue genetic changes

...wn, but some of the changes resemble those seen in cancerous cells. At any rate, the changes presumably became entrenched in a particular cell line because they conferred some advantage as the cells were grown in laboratory dishes. Whether the changes affect the stem cells' abilities to become other cell types...

UT Southwestern researchers develop screening test for cells that activate immune system

...tant recon patrol throughout the body to scout out cancerous or infected cells and alert the immune system. "Our assay is unique from other conventional ones in its sensitivity and cost- and time-efficiency," said Dr. Akira Takashima, professor of dermatology and vice chairman for research and head of the pro...

Scientists develop nanotech-laser treatment that kills cancer cells without harming healthy tissue

...cently conducted a similar experiment on mice with cancerous tumors. Instead of carbon nanotubes, the Rice team injected the tumors with gold-coated nanoshells and exposed the animals to near-infrared light for several minutes. The tumors disappeared within 10 days without damaging any healthy tissue. Future ...

Study hints at role of stem cell genes in testicular, breast cancers

...n of sperm-producing germ cells. Next, turning to cancerous tissue outside of the reproductive system, in this case breast tissue, the team determined, to their surprise, that the expression of the genes was active there, too. "We thought this was going to be a phenomenon unique to germ cell tumors," says th...
