Tumorigenesis is the process involved in the production of a new tumor or tumors.
A*STAR scientists from the Institute of Molecular and Cell Biology (IMCB) and the Singapore Bioimaging Consortium (SBIC) have discovered a new signalling pathway that controls both obesity and atherosclerosis.
MorphoSys AG's (FSE: MOR; Prime Standard Segment, TecDAX) partner OncoMed Pharmaceuticals today announced that Proceedings of the National Academy of Sciences of the United States of America (PNAS) has published online data demonstrating the potent anti-cancer activity of OMP-18R5, a HuCAL antibody targeting the Wnt pathway, in multiple preclinical human tumor models. OMP-18R5 is currently in Phase 1 clinical testing.
Researchers in Japan who evaluated the risks and efficacy of transplanting two varieties of stem cells into mouse cochlea have concluded that both adult-derived induced pluripotent stem (iPS) cells and mouse embryonic stem (ES) cells demonstrate similar survival and neural differentiation capabilities.
Double-stranded breaks in cellular DNA can trigger tumorigenesis. Researchers from Ludwig-Maximilians-Universitaet (LMU) in Munich have now determined the structure of a protein involved in the repair and signaling of DNA double-strand breaks. The work throws new light on the origins of neurodegenerative diseases and certain tumor types.
Johns Hopkins researchers say they have discovered one of the most important cellular mechanisms driving the growth and progression of meningioma, the most common form of brain and spinal cord tumor. A report on the discovery, published in the journal Molecular Cancer Research, could lead the way to the discovery of better drugs to attack these crippling tumors, the scientists say.

A study by Travis H. Stracker, researcher at the Institute for Research in Biomedicine (IRB Barcelona), in collaboration with scientists at the Memorial Sloan Kettering Cancer Center (MSKCC) in New York, reveals new information about the origin of tumors.
Cancer researchers have known for well over a century that different tumor types spread only to specific, preferred organs. But no one has been able to determine the mechanisms of organ specific metastasis, the so-called "soil and seed" theory of 1889. New details that could help shed light on this hypothesis have been provided by a team of researchers from Weill Cornell Medical College, Memorial Sloan-Kettering Cancer Center, and their collaborators, proposing a new mechanism controlling cancer metastasis that offers fresh diagnostic and treatment potential.
Chromosomal deletions in DNA often involve just one of two gene copies inherited from either parent. But scientists haven't known how a deletion in one gene from one parent, called a "hemizygous" deletion, can contribute to cancer.
PCI Biotech (PCIB) the Norwegian biopharmaceutical company, reported today that the first patient has been included in the phase II study of Amphinex in combination with the cytotoxic agent bleomycin in head and neck cancer patients, called the ENHANCE study. The first patient was included at the National Center for Tumor Diseases (NCT), University Hospital Heidelberg, Germany. NCT is a joint project of the German Cancer Research Center (DKFZ), Heidelberg University Hospital, Thoraxklinik Heidelberg and Deutsche Krebshilfe (German Cancer Aid).
The new Randox Acusera multi-analyte Liquid Tumour Marker Control covers a total of 15 commonly tested and esoteric cancer antigens and tumour markers. The addition of assayed target values enables laboratories to effectively monitor both accuracy and precision.
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.
