Tumorigenesis is the process involved in the production of a new tumor or tumors.
Researchers from the Bellvitge Biomedical Research Institute (IDIBELL) have shown that overactivation of the RANK signalling pathway promotes the initiation, progression and metastasis of tumours in human breast epithelial cells by dedifferentiation of breast cells to stem cells. The results of this study have been advanced in the electronic edition of the journal Cancer Research.
Scientists from Duke University Medical Center have determined that genes acting as molecular "on/off" switches can define clinically relevant molecular subtypes of ovarian cancer, providing ideal potential targets for use in clinical prognostic and diagnostic testing.
Kaposi's sarcoma herpesvirus (KSHV) is a human tumor virus and an etiological agent for Kaposi's sarcoma and primary effusion lymphoma (PEL). PELs are aggressive lymphomas with reported median survival time shorter than six months after diagnosis.
Breast cancer represents about a fifth of all cancers diagnosed in women. The reasons for the rapid progression of the disease remain relatively poorly understood but recent work in the group of Veronika Sexl at the University of Veterinary Medicine, Vienna has pointed the finger strongly at loss or inactivation of the transcription factor STAT1.
Although it's widely accepted that inflammation is a critical underlying factor in a range of diseases, including the progression of cancer, little is known about its role when normal cells become tumor cells. Now, scientists from the Florida campus of The Scripps Research Institute have shed new light on exactly how the activation of a pair of inflammatory signaling pathways leads to the transformation of normal breast cells to cancer cells.
Researchers at The Pennsylvania State University College of Medicine, Hershey, Pennsylvania have discovered that the presence and integrity of the opioid growth factor receptor (OGFr), which mediates the inhibitory action of opioid growth factor (OGF) on cell proliferation, is a key to understanding the progression and treatment of human ovarian cancer.
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.
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.
The Damon Runyon Cancer Research Foundation announced that five scientists with novel approaches to fighting cancer have been named 2012 recipients of the Damon Runyon-Rachleff Innovation Award.
The Damon Runyon Cancer Research Foundation, a non-profit organization focused on supporting innovative early career researchers, named 18 new Damon Runyon Fellows at its fall Fellowship Award Committee review.
Recent findings in mice suggest that blocking the production of small molecules produced in the body, known as epoxyeicosatrienoic acids (EETs), may represent a novel strategy for treating cancer by eliminating the blood vessels that feed cancer tumors.
A jumping gene with the fairy tale name "Sleeping Beauty" has helped to unlock vital clues for researchers investigating the genetics of colorectal cancer.
Like snakes, tumour cells shed their skin. Cancer is not a static disease but during its development the disease accumulates changes to evade natural defences adapting to new environmental circumstances, protecting against chemotherapy and radiotherapy and invading neighbouring organs, eventually causing metastasis.
The hormone receptor guanylyl cyclase C (GCC) has been established as a suppressor of colorectal cancer tumors, but new evidence from Thomas Jefferson University suggests it may also help fight one of the country's biggest pandemics: obesity.
Using a new in vivo screening system, Whitehead Institute researchers have identified a protein in the serine biosynthesis pathway that is essential in estrogen receptor (ER)-negative breast cancer—a notoriously difficult disease to treat associated with low five-year survival rates.
CANCER RESEARCH UK scientists have revealed that a 'detox' protein which mops up harmful 'reactive oxygen' in cells could also trigger pancreatic and lung cancer development, according to a study published in Nature, today.
A team of researchers led by scientists at the University of California, San Francisco has developed a way to uncover the evolution of human cancer cells, determining the order in which mutations emerge in them as they wend their way from a normal, healthy state into invasive, malignant masses.
LifeVantage Corporation, the maker of Protandim, a clinically demonstrated, science-based therapy for the reduction of oxidative stress by the synergistic activation of Nrf2, announced today that a new peer-reviewed review article involving Protandim was published in the scientific journal Enzyme Research.
FibroGen, Inc., today announced proof-of-principle for oral anemia therapy FG-4592, a hypoxia-inducible factor (HIF) prolyl hydroxylase inhibitor, in end-stage renal disease patients receiving hemodialysis.
A new study shows how inflammation can help cause cancer. Chronic inflammation due to infection or to conditions such as chronic inflammatory bowel disease is associated with up to 25 percent of all cancers.
