New information on molecular biology of KRas protein

KRas is one of the usual suspects in cancer. It is a protein that is mutated in 30% of human tumors and has been implicated in the regulation of many cell signalling pathways.

New insights into transcription factors in human cells

Bioinformatics researchers from UC San Diego just moved closer to unlocking the mystery of how human cells switch from "proliferation mode" to "specialization mode."

Overexpression of PEA-15 protein shrinks breast cancer tumors

Overexpression of PEA-15, which binds and drags an oncoprotein out of the cell nucleus where it fuels cancer growth, steeply reduced breast cancer tumors in a preclinical experiment, researchers at The University of Texas M. D. Anderson Cancer Center reported at the 100th annual meeting of the American Association for Cancer Research.

Genetic source of rare cancer pleuropulmonary blastoma discovered

The search for the cause of an inherited form of a rare, aggressive childhood lung cancer has uncovered important information about how the cancer develops and potentially sheds light on the development of other cancers.

Fulvestrant influences the effects of chemotherapy drugs on breast cancer cells

Researchers from The Cancer Institute of New Jersey (CINJ) are converging on Denver for the 100th Annual Meeting of the American Association for Cancer Research (AACR) to share their findings on a combined treatment targeting breast cancer that is stimulated by the hormone estrogen (estrogen receptive positive).

First noninvasive technique to accurately predict mutations in human brain tumors

Donald O'Rourke, MD, Associate Professor of Neurosurgery at the University of Pennsylvania School of Medicine and colleagues, were able to accurately predict the specific genetic mutation that caused brain cancer in a group of patients studied using magnetic resonance imaging (MRI).

Nanoparticle delivery of a fully functioning copy of P53 tumor suppressor gene

Dr. Esther Chang describes the most recent developments in human trials of the first systemic, non-viral, tumor-targeted, nanoparticle method designed to restore normal gene function to tumor cells while completely bypassing normal tissue April 21 at an American Association of Anatomists (AAA) scientific session at Experimental Biology 2009 in New Orleans.

Researchers identify mechanism by which an anti-TNF therapy impairs host defense against tuberculosis

The life of many individuals with inflammatory diseases such as rheumatoid arthritis has been dramatically improved by treatment with drugs that target the protein TNF, so called anti-TNF therapies.

Chemopreventive isothiocyanates selectively depletes mutant p53 in tumor cells

Researchers at Lombardi Comprehensive Cancer Center at Georgetown University Medical Center have demonstrated that naturally-occurring compounds can selectively deplete mutant p53 and restore "wild type" function to p53 in a variety of tumor cells.

Eggs for breakfast help manage hunger and calorie consumption

New studies presented this week at Experimental Biology 2009 enhance the growing body of evidence supporting the nutritional benefits of eggs.

Protein FGFR3 a potential therapeutic target for several cancers

Several forms of cancer, including bladder cancer and multiple myeloma caused by the t(4;14) genetic abnormality, are associated with either overexpression or perpetual activation of the protein FGFR3.

Fish oil protects against neurodegenerative diseases

Dr. Nicolas Bazan, Director of the Neuroscience Center of Excellence, Boyd Professor, and Ernest C. and Yvette C. Villere Chair of Retinal Degenerative Diseases Research at LSU Health Sciences Center New Orleans, will present new research findings showing that an omega three fatty acid in the diet protects brain cells by preventing the misfolding of a protein resulting from a gene mutation in neurodegenerative diseases like Parkinson's and Huntington's.

Research shows how p53 mutations link to high-grade breast cancer, poor outcomes

In what is believed to be the largest study of its kind in the US, researchers have found that almost 26 percent of women studied who have breast cancer have mutations in a gene important in controlling cell growth and death, and that patients with mutations in this gene - known as p53 - had poorer outcomes including a significantly increased risk of death from the cancer.

Key genetic mechanism a potential key to new class of antibiotics

Researchers have determined the structure of a key genetic mechanism at work in bacteria, including some that are deadly to humans, in an important step toward the design of a new class of antibiotics, according to an accelerated publication that appeared online today as a "paper of the week" in the Journal of Biological Chemistry.
