Genomic instability allows malignant cells to acquire more deadly characteristics

Genomic instability caused by an erosion of the protective caps on chromosomes, followed by activation of an enzyme that reinforces those aps, allows malignant cells to evade destruction and acquire more deadly characteristics, researchers report in an Online Now article at the journal Cell.

Telomerase reactivation in malignant cells after genomic instability causes cancer progression

Inhibiting telomerase, an enzyme that rescues malignant cells from destruction by extending the protective caps on the ends of chromosomes, kills tumor cells but also triggers resistance pathways that allow cancer to survive and spread, scientists report in the Feb. 17 issue of Cell.

Targeting patient's own dendritic cells may help restore the immune system

Aggressive ovarian tumors begin as malignant cells kept in check by the immune system until, suddenly and unpredictably, they explode into metastatic cancer. New findings from scientists at The Wistar Institute demonstrate that ovarian tumors don't necessarily break "free" of the immune system, rather dendritic cells of the immune system seem to actively support the tumor's escape.

UK's leading model agencies back 'No Sunbed' campaign

Ahead of London Fashion Week, leading model agencies sign groundbreaking 'No Sunbed' policy agreement as part of Cancer Research UK's R UV UGLY? campaign after warnings on health and appearance

New transfection method changes genetic material of cancer cells

Researchers at Polytechnique Montr-al have succeeded in changing the genetic material of cancer cells using a brand-new transfection method. This major breakthrough in nanosurgery opens the door to new medical applications, among others for the treatment of cancers.

UC Cancer Institute to enroll up to 60 patients for AMG 595 phase-1 trial

The UC Cancer Institute is one of three centers internationally approved to test an experimental drug's safety and pharmacokinetics and also assess the clinical benefit against recurrent malignant glioma, an aggressive form of brain cancer.

TFF3 protein plays a more sinister role in breast cancer metastasis

The trefoil factor 3 (TFF3) protein protects and maintains the integrity of the epithelial surface in the normal breast. New research has found that while TFF3 protein expression is higher in well-differentiated low grade tumors and therefore associated with features of a good prognosis, it has a more sinister role in breast cancer invasion and metastasis.

Juvenile arthritis affected kids are at a high risk of cancer: Study

A new study shows that kids with juvenile idiopathic arthritis develop cancer four times more often than children without the disease, but the treatments they receive - including biologic treatments like Enbrel - may not explain their increased risk. If confirmed, researchers say the findings should ease fears that biologic treatments known as TNF inhibitors cause cancer in children and young adults.

Epigenetic mechanisms maintain tolerance in T cells specific for self antigens

At the most basic level, the immune system must distinguish self from non-self, that is, it must discriminate between the molecular signatures of invading pathogens (non-self antigens) and cellular constituents that usually pose no risk to health (self-antigens).

OncoSec to commence OMS ElectroImmunotherapy Phase II trial in MCC

OncoSec Medical Incorporated, which is developing its advanced-stage OncoSec Medical System (OMS) ElectroOncology therapies to treat solid tumor cancers, today announced that physicians at the University of Washington and Seattle Cancer Care Alliance in conjunction with the Fred Hutchinson Cancer Center, have treated several patients in an open-label Phase II clinical trial evaluating OncoSec's OMS ElectroImmunotherapy for the treatment of Merkel cell carcinoma.

Incident malignancy four times higher among children with JIA

New research reports that incident malignancy among children with juvenile idiopathic arthritis (JIA) is four times higher than in those without the disease. Findings now available in Arthritis & Rheumatism, a journal published by Wiley-Blackwell on behalf of the American College of Rheumatology (ACR), suggest JIA treatment, such as tumor necrosis factor (TNF) inhibitors, does not necessarily explain the development of cancer in this pediatric population.

Preliminary results from Soligenix SGX201 Phase 1/2 trial on acute radiation enteritis

Soligenix, Inc., a development stage biopharmaceutical company, announced preliminary results today from a Phase 1/2 clinical trial evaluating SGX201, a time-release formulation of oral beclomethasone 17,21-dipropionate (oral BDP), for the prevention of acute radiation enteritis.

New 3D computer model to understand cancer development

Observing that certain cancer cells may exhibit greater flexibility than normal cells, some scientists believe that this capability promotes rapid tumor growth. Now computer simulations developed by Boston University Biomedical Engineering Assistant Professor Muhammad Zaman and collaborators at the University of Texas at Austin appear to support this view.

Link between coronary artery disease and prostate cancer

In a large analysis of men participating in a prostate drug trial, researchers at the Duke Cancer Institute found a significant correlation between coronary artery disease and prostate cancer, suggesting the two conditions may have shared causes.

ACR, AdMeTech and ESUR to expedite development of standards for MR PI-RADS

To improve early diagnosis and treatment of prostate cancer, ACR, AdMeTech Foundation and ESUR have formed a joint effort to expedite development of standards for the Magnetic Resonance Prostate Imaging Reporting and Data System (MR PI-RADS) modeled after a successful effort in breast cancer care

Researchers discover function and expression of CD97 in malignant gliomas

Researchers at Virginia Commonwealth University Medical Center's VCU Massey Cancer Center and Harold F. Young Neurosurgical Center and Old Dominion University have discovered that suppression of Wilms tumor 1 protein (WT1) results in downregulation of CD97 gene expression in three glioblastoma cell lines and reduces the characteristic invasiveness exhibited by glial tumor cells.

Cyclin D1 oncogene may promote chromosomal instability

A team of researchers at Jefferson's Kimmel Cancer Center (KCC) led by Richard G. Pestell, M.D., PhD., FACP, Director of the KCC and Chair of the Department of Cancer Biology, have shown in a study published online Feb. 6 in the Journal of Clinical Investigation that the oncogene cyclin D1 may promote a genetic breakdown known as chromosomal instability (CIN). CIN is a known, yet poorly understood culprit in tumor progression.
