Engineered virus targets and kills apparent cancer stem cells in neuroblastoma

After identifying an apparent population of cancer stem cells for neuroblastoma, researchers successfully used a reprogrammed herpes virus to block tumor formation in mice by targeting and killing the cells.

Study examines racial disparities in survival among patients diagnosed with lung cancer

Disparities in survival among black patients diagnosed with early-stage lung cancer are not seen when patients are recommended appropriate treatment, according to a report in the January issue of Archives of Surgery.

Gene switch sites found mainly on 'shores,' not just 'islands' of the human genome

Scientists who study how human chemistry can permanently turn off genes have typically focused on small islands of DNA believed to contain most of the chemical alterations involved in those switches.

Transarterial chemoembolization as liver cancer treatment

Using tiny chemotherapy-soaked beads to choke off and kill cancerous liver tumors is becoming more successful, according to research being presented at the 21st annual International Symposium on Endovascular Therapy (ISET).

Researchers find novel use for old compound in cancer treatment

The compound, alpha-difluoromethylornithine or DFMO, targets the activity of a specific enzyme and, even in very limited doses, is effective in protecting against the malignancy in animal models.

Exercise after menopause lowers breast cancer risk

Several studies had previously suggested that regular physical exercise reduces the breast cancer risk of women.

Artificial antibody delivers nanoparticles to tumors

Antibodies that target epidermal growth factor receptor (EGFR) have proven themselves as potent anticancer drugs. Now, a team of investigators led by Shuming Nie, Ph.D., and Lily Yang, Ph.D., both at the Emory University School of Medicine and members of the Emory-Georgia Tech Nanotechnology Center for Personalized and Predictive Oncology, is aiming to capitalize on this targeting ability, using a modified anti-EGFR antibody to delivery nanoparticles into tumor cells.

Toxin-nanoparticle combo inhibits brain cancer invasion while imaging tumors

Working with a nanoparticle designed to target and image glioblastoma, a form of brain cancer, investigators at the University of Washington in Seattle have found that these same nanoparticles inhibit tumor cell invasion, one of the key events that leads to the metastatic spread of cancer. The investigators have also determined how the nanoparticles exert this potentially beneficial effect.

Polymer nanoparticle for oral anticancer drug delivery

One of the problems that cancer patients face is that many of the most potent anticancer therapies can be administered only by injection, which means that cancer patients must travel to receive their medication. But thanks to a new type of nanoparticle developed by researchers at the Johns Hopkins University School of Medicine, future cancer patients may be able to receive their medication in pill form.

Study shows how defective DNA repair triggers 2 neurological diseases

Scientists at St. Jude Children's Research Hospital have teased apart the biological details distinguishing two related neurological diseases-ataxia telangiectasia-like disease (ATLD) and Nijmegen breakage syndrome (NBS).

Stem cells could be used for personalized cancer treatment

Using cancer cells from an ovarian cancer patient and human embryonic stem cells, Israeli researchers have created a cancerous tumor in a mouse that mimics the way the tumor would develop in the patient's body.

Advaxis wins European patent case involving Lovaxin-C vaccine

The European Patent Court in Munich, Germany has ruled in favor of Advaxis Incorporated and reversed a patent challenge made by Anza Therapeutics, Inc., formerly Cerus Corp.

Treatment may need to be modified for elderly glioblastoma patients

Glioblastoma, the most common and aggressive type of brain tumor, accounts for a majority of the brain tumors seen in patients 65 years or older.

Variations in mismatch repair genes predict prognosis in pancreatic cancer

Variations in mismatch repair genes can help predict treatment response and prognosis in patients with pancreatic cancer, according to research from The University of Texas M. D. Anderson Cancer Center presented today in advance of the American Society of Clinical Oncology (ASCO) Gastrointestinal Cancers Symposium.

Gene therapy kills brain tumors through selective recruitment of immune cells

Scientists seeking to harness the power of the immune system to eradicate brain tumors face two major hurdles: recruiting key immune cells called dendritic cells into areas of the brain where they are not naturally found and helping them recognize tumor cells as targets for attack.

Discovery of new regulatory circuit controlling immune cell production in mice

Using a mouse model, researchers have shown that elevated levels of a small protein known as interleukin 7 (IL-7) plays a central role in regulating the production of a type of white blood cell that is required for effective immune responses.

Researchers find genes that fuse in cancer

Using new technologies that make it easier to sequence the human genome, researchers at the University of Michigan Comprehensive Cancer Center have identified a series of genes that become fused when their chromosomes trade places with each other.

New evidence in support of Warburg theory of cancer

German scientist Otto H. Warburg's theory on the origin of cancer earned him the Nobel Prize in 1931, but the biochemical basis for his theory remained elusive.

Statistical analysis of bladder cancer

Bladder cancer is much more likely to be deadly for women and African-Americans, but the reasons long believed to explain the phenomenon account for only part of the differences for such patients compared to their white and male counterparts, according to results published in the Jan. 1 issue of the journal Cancer.

Novel low-cost immunotherapy for cancer cells

Molecules of sugar sitting on the surface of cancer cells are keys to the development of a new vaccine aimed at both treating and stopping the spread of certain types of cancers called carcinomas, which include prostate, breast, ovarian and lung, among others.
