Tumorigenesis is the process involved in the production of a new tumor or tumors.

Better understanding of environmental influences on the aging process of stem cells

A stem cells' immediate neighborhood, a specialized environment also known as the stem cell niche, provides crucial support needed for stem cell maintenance.

DNA damage response confers a barrier for viral tumorigenesis

Kaposi's sarcoma herpesvirus (KSHV) is a human tumor virus and an etiological agent for Kaposi's sarcoma (KS).

Coding and noncoding genes are involved in and cooperate in human tumorigenesis

A new study provides evidence that noncoding RNAs and interactions between noncoding genes play a much greater role in human cancer than was previously understood.

Interleukin-6 - new target in the battle against Ras-induced cancers

In an upcoming Genes & Development paper, Dr. Christopher Counter and colleagues at the Duke University Medical Center have identified IL6 as a new target in the battle against Ras-induced cancers.

Notch2 locus predicts prognosis in brain tumor patients

PLoS ONE has just published a study which defines a gene locus on chromosome 1 that predicts prognosis of brain tumor patients and may even set the basis for the development of more efficient drugs to combat brain cancer.

The unexpected connection of two gene regulation mechanisms points to new ways for the fight against leukemia

When the activity of individual genes it is longer required, there are two main mechanisms responsible for the “switching off”, mainly DNA methylation and the Polycomb protein complex. Sometimes, these mechanisms lose their efficiency and some of the genes that should be "switched off" remain active.

Gamma-secretase acts as a tumor suppressor

Researchers at Burnham Institute for Medical Research (Burnham) have provided the first evidence that gamma-secretase, an enzyme key to the progression of Alzheimer's, acts as a tumor suppressor by altering the pathway of epidermal growth factor receptor (EGFR), a potential treatment target for cancer.

Detailed portrait of 700 proteins that help maintain DNA integrity

Cells have the remarkable ability to keep track of their genetic contents and -- when things go wrong, to step in and repair the damage before cancer or another life-threatening condition develops.

Scientists develop method to track immune system enzyme in live animals

Scientists supported by the National Institute of Arthritis and Musculoskeletal and Skin Diseases (NIAMS) at the National Institutes of Health have created two mouse strains that will permit researchers to trace, in a live animal, the activity of an enzyme believed to play a crucial role both in the normal immune response as well as autoimmunity and B cell tumor development.

Researchers identify genetic markers associated with breast cancer tumor grade and lymph node metastases

Researchers have identified genetic markers on several chromosomes in the tissue surrounding tumor cells that are associated with breast cancer tumor grade and the presence of lymph node metastases, according to a study in the May 16 issue of JAMA.

Protein findings establish better understanding of tumor development

Peter Baumann, Ph.D., Assistant Investigator, and Nancy Bae, Ph.D., Postdoctoral Research Associate in the Baumann Lab, have published a paper offering insight into the way cells protect chromosome ends from misguided repair.

microRNAs can function as tumor suppressors

University of Virginia researchers have discovered that microRNAs, a form of genetic material, can function as tumor suppressors in laboratory studies.

New discoveries about stem cells in leukemia, breast and colon cancer

Recent discoveries about the role of stem cells in cancer have altered the landscape of cancer research. With each new study, scientists are learning more about cancer-initiating properties of stem cells at organ sites and throughout the body.

New insights into renal cell cancer

A new mouse model is providing valuable insight into the biochemical pathways that are associated with development of renal cysts and renal cell cancer.

Preventing cancer without killing cells

Inducing senescence in aged cells may be sufficient to guard against spontaneous cancer development, according to a paper published online this week in EMBO reports.

Scientists discover new approach for treating virus-induced lymphomas

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.

Gene mutation potentially involved in breast cancer initiation

Researchers have found evidence suggesting that a mutation in a gene that normally helps block the formation of breast tumors could play a role in the initiation of a major form of breast cancer.

Novel animal model of lung adenocarcinoma

Drs. Katerina Politi, Harold Varmus and colleagues at the Memorial Sloan Kettering Cancer Center in New York have developed a novel animal model of lung adenocarcinoma that will be of great use in testing the efficacy of targeted therapies against human lung cancer.

Cathepsin inhibitors as cancer therapies

In the March 1 issue, Drs. Johanna Joyce (MSKCC), Douglas Hanahan (UCSF) and colleagues lend new insight into how broad-spectrum cysteine cathepsin inhibitors combat pancreatic cancer, and provide new data to help refine the design of more precisely targeted anti-cathepsin therapies.

Nod1 found to control tumor growth in certain breast cancers

This protein was previously thought to play a role solely in the innate immune system's response to bacterial infection. In the new study, which will be published on-line by the Proceedings of the National Academy of Sciences
