Study shows cancer cell death via necroptosis can drive pancreatic tumor growth

The most aggressive form of pancreatic cancer - often described as one of the hardest malignancies to diagnose and treat -- thrives in the presence of neighboring tumor cells undergoing a particular form of "orchestrated cell death." This is according to a major study recently published in the journal Nature.

Scientists find that lifespan of supportive cells in tumor may control cancer metastasis

Researchers have discovered that eliminating cells thought to aid tumor growth did not slow or halt the growth of cancer tumors. In fact, when the cancer-associated fibroblasts (CAFs), were eliminated after 10 days, the risk of metastasis of the primary tumor to the lungs and bones of mice increased dramatically.

Wistar researchers find potential way for using STAT3 inhibitors to stop cancer progression

Imagine developing a drug designed to inhibit a protein that helps cancer cells proliferate and survive only to find that the drug does not perform very well in the clinic. This was the dilemma faced by scientists researching inhibitors of signal transducer and activator of transcription (STAT3), a protein that controls transcription by the STAT3 gene.

MGH study reveals effects of obesity on pancreatic and breast cancer

Massachusetts General Hospital investigators may have uncovered a novel mechanism behind the ability of obesity to promote cancer progression. In their report published online in the journal Clinical Cancer Research, the research team describes finding an association between obesity and an overabundance of a factor called PlGF (placental growth factor) and that PlGF's binding to its receptor VEGFR-1, which is expressed on immune cells within tumors, promotes tumor progression.

MGH researchers find how metformin drug prevents progression of pancreatic cancer

Massachusetts General Hospital investigators may have uncovered a novel mechanism behind the ability of the diabetes drug metformin to inhibit the progression of pancreatic cancer.

Novel technique may help women and their oncologists choose options for treating breast cancer

Biomedical engineers have demonstrated a proof-of-principle technique that could give women and their oncologists more personalized information to help them choose options for treating breast cancer.

Researchers make major step toward finding target to combat drug-resistant neuroblastoma

Researchers at Children's Hospital Los Angeles have made an important step toward finding a target in the fight against drug-resistant neuroblastoma (NBL), the most common solid malignancy found, outside of the skull, in children.

Game theory and the cancer ecosystem: an interview with Professor Pienta, Johns Hopkins

The classic description of game theory was described by the prisoner's dilemma, which is a situation in which two players have two options where the outcome depends on the simultaneous choice made by the other.

Study: CD206-targeting Manocept platform may provide potential avenues to enhance diagnosis in Kaposi Sarcoma

Navidea Biopharmaceuticals, Inc. (NYSE MKT: NAVB), a biopharmaceutical company focused on precision diagnostic radiopharmaceuticals, today announced that collaborators from the University of California, San Francisco (UCSF) presented results at the 2014 American Association for Cancer Research (AACR) conference, April 5-9, 2014 in San Diego, CA, highlighting the potential utility of imaging agents derived from Navidea's Manocept™ platform in identifying affected tissues and lymph nodes in patients with Kaposi Sarcoma (KS).

Study demonstrates direct effects of fragmented sleep on tumor growth

Poor-quality sleep marked by frequent awakenings can speed cancer growth, increase tumor aggressiveness and dampen the immune system's ability to control or eradicate early cancers, according to a new study published online January 21, 2014, in the journal Cancer Research.

Experimental drug that targets macrophages decreases cancer's growth

An experimental drug that targets macrophages, a type of immune cells, in the microenvironment surrounding the lethal brain tumor glioblastoma multiforme decreased the cancer's growth and extended survival of laboratory mice with the cancer, scientists will report on Tuesday Dec. 17, at the American Society for Cell Biology annual meeting in New Orleans.

New mechanism explains why anti-tumor activity of specific immune suppressed during tumor growth

The Leuven-based VIB researchers have revealed a mechanism that explains why the anti-tumor activity of specific immune cells called macrophages is suppressed during tumor growth. They have also demonstrated that blocking the protein Nrp1 can restore this anti-tumor immune response.

Verastem presents positive results from VS-6063 clinical and preclinical studies at 2013 AACR-NCI-EORTC meeting

Verastem, Inc., focused on discovering and developing drugs to treat cancer by the targeted killing of cancer stem cells, announced positive results from the Phase 1 portion of its Phase 1/1b study of defactinib (VS-6063) in combination with paclitaxel in patients with ovarian cancer that were presented at the 2013 AACR-NCI-EORTC International Conference on Molecular Targets and Cancer Therapeutics in Boston.

Stromal cells offer chemotherapy clue in early lung cancer

Podoplanin-positive cancer-associated fibroblasts predict recurrence in stage I lung adenocarcinoma, which could help identify patients suited for adjuvant chemotherapy, research shows.

Advanced papillary thyroid cancer patients with BRAFV600E gene mutation at higher risk

Individuals with advanced papillary thyroid cancer (PTC) that are associated with the BRAFV600E gene mutation have a higher risk of recurrent disease and progression to more advanced, poorly differentiated thyroid cancer, according to data presented today at the 81st Annual Meeting of the American Thyroid Association (ATA).

Plexxikon commences PLX3397 Phase 2 trial in patients with Hodgkin lymphoma

Plexxikon today announced that it has treated the first patient in a Phase 2 clinical trial in Hodgkin lymphoma with PLX3397. This novel agent is an oral, selective inhibitor that down-modulates two key cell types that are thought to mediate the progression of Hodgkin lymphoma tumors — macrophages and mast cells.

HRG protein inhibits tumor growth and metastasis: Study

Most cancer tissues are invaded by inflammatory cells that either stimulate or inhibit the growth of the tumor, depending on what immune cells are involved. Now a Swedish-Belgian research team has shown that a protein that naturally occurs in the body, HRG, inhibits tumor growth and metastasis into secondary organs by activating specific immune cells.

Study shows breast inflammation promotes development and progression of cancer

It took 12 years and a creation of a highly sophisticated transgenic mouse, but researchers at Kimmel Cancer Center at Jefferson have finally proven a long suspected theory: Inflammation in the breast is key to the development and progression of breast cancer.

hBD-3 biomarker helps early stage detection of oral cancer

Detecting oral cancer in its earliest stages can save the lives of the nearly 40,500 people diagnosed annually. But early detection has been difficult. Case Western Reserve University School of Dental Medicine researchers discovered a biomarker, called human beta defensin-3 (hBD-3), which may serve as an early warning. The defensin is present in all oral cancers and associated with the early stages of oral cancer.
