Mitochondria may be promising new target for cancer treatment

Mitochondria, tiny structures within each cell that regulate metabolism and energy use, may be a promising new target for cancer therapy, according to a new study. Manipulation of two biochemical signals that regulate the numbers of mitochondria in cells could shrink human lung cancers transplanted into mice, a team of Chicago researchers report in the journal FASEB.

Thrombocytosis linked to severity of ovarian cancer

Highly elevated platelet levels fuel tumor growth and reduce the survival of ovarian cancer patients, an international team of researchers led by scientists at The University of Texas MD Anderson Cancer center reports in the New England Journal of Medicine.

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).

Gene therapy to promote remyelination in mouse model of MS

Our bodies are full of tiny superheroes-antibodies that fight foreign invaders, cells that regenerate, and structures that ensure our systems run smoothly. One such structure is myelin-a material that forms a protective, insulating cape around the axons of our nerve cells so that they can send signals quickly and efficiently. But myelin, and the specialized cells called oligodendrocytes that make it, become damaged in demyelinating diseases like multiple sclerosis (MS), leaving neurons without their myelin sheaths.

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.

Soy isoflavone supplements do not reduce breast cancer cell proliferation

Soy isoflavone supplements did not decrease breast cancer cell proliferation in a randomized clinical trial, according to a study published in Cancer Prevention Research, a journal of the American Association for Cancer Research.

Exelixis reports preliminary data from cabozantinib phase 1b trial on RCC

Exelixis, Inc. today reported preliminary data from a cohort of heavily pretreated patients with metastatic refractory renal cell carcinoma (RCC) participating in an ongoing phase 1b trial of cabozantinib.

Scientists connect two signature characteristics of pancreatic cancer

Scientists have connected two signature characteristics of pancreatic cancer, identifying a self-perpetuating "vicious cycle" of molecular activity and a new potential target for drugs to treat one of the most lehal forms of cancer.

Scientists evaluate growth, differentiation and function of iPSC-derived NPCs in PD

Induced pluripotent stem cells (iPSC) are a promising avenue for cell replacement therapy in neurologic diseases. For example, mouse and human iPSCs have been used to generate dopaminergic (DA) neurons that improve symptoms in rat Parkinson's disease models. Reporting in the current issue of the Journal of Parkinson's Disease, a group of scientists from Japan evaluated the growth, differentiation, and function of human-derived iPSC-derived neural progenitor cells (NPCs) in a primate model, elucidating their therapeutic potential.

Cocoa can help prevent onset of colon carcinogenesis

A new study on living animals has shown for the first time that eating cocoa (the raw material in chocolate) can help to prevent intestinal complaints linked to oxidative stress, including colon carcinogenesis onset caused by chemical substances.

Five scientists named recipients of Damon Runyon-Rachleff Innovation Award for cancer research

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.

Positive preliminary data from Exelixis' cabozantinib phase 2 trial on HCC

Exelixis, Inc. today reported positive preliminary data from the cohort of hepatocellular carcinoma (HCC) patients participating in the ongoing phase 2 randomized discontinuation trial (RDT) of cabozantinib.

Combination of gefitinib and miRNA-inhibitor might effectively treat NSCLC

New research published in Nature Medicine indicates that targeted drugs such as gefitinib might more effectively treat non-small cell lung cancer if they could be combined with agents that block certain microRNAs.

Clues about how statins might treat breast cancer

Cholesterol-lowering statins seem to keep breast cancer at bay in some patients. Now researchers reporting in the January 20th issue of the journal Cell, a Cell Press publication, provide clues about how statins might yield those unexpected benefits. The findings also suggest that mutations in a single gene could be used to identify tumors likely to respond to statin therapy.

Study shows how to stop brain cancer cell proliferation and migration

Brain cancer is hard to treat: it's not only strong enough to resist most chemotherapies, but also nimble enough to migrate away from radiation or surgery to regrow elsewhere. New research at the University of Colorado Cancer Center shows how to stop both.

Regorafenib lengthens lives of patients with metastatic colorectal cancer

An investigational drug called regorafenib slowed the progression of tumors and lengthened the lives of patients with metastatic colorectal cancer, an international phase III clinical trial found. The findings were presented today at the Gastrointestinal Cancers Symposium of the American Society of Clinical Oncology in San Francisco by Mayo Clinic oncologist Axel Grothey, M.D., principal investigator of the trial in the United States.

Experts recommend vitamin D supplementation for menopausal women

A group of experts has prepared a report on vitamin D supplementation for menopausal women after it was revealed that Europeans have suffered an alarming decrease in their levels of this vitamin. In their opinion, the ideal would be to maintain blood levels above 30 ng/ml. Vitamin D is essential to the immune system and processes such as calcium absorption.
