Blood 'metabolomics' study uncovers liver, heart, and kidney toxicity in healthy smokers

Examining the blood "metabolomics" profile of smokers immediately after they had a cigarette revealed activation of pathways involved in cell death, inflammation, and other forms of systemic damage, say researchers at Georgetown Lombardi Comprehensive Cancer Center, part of Georgetown University Medical Center.

S.A.N.E. Vax calls for federal approval of reliable HPV genotyping test in cervical cancer prevention programs

In a letter addressed to Dr. Harold E. Varmus, director of the NCI, and Dr. Margaret Hamburg, FDA commissioner, Ms. Norma Erickson, president of S.A.N.E. Vax, Inc., requested that these two federal agencies recommend a reliable human papillomavirus (HPV) genotyping test to support the national virology-based cervical cancer prevention program for patient care. Erickson stated: "The NCI knows reliable HPV genotyping is based on using a PCR system with short target sequencing."

Gefitinib exhibits potential as chemoprevention agent for pancreatic cancer

Gefitinib may be a promising chemoprevention agent for pancreatic cancer, according to a study published in Cancer Prevention Research, a journal of the American Association for Cancer Research.

Researchers examine impact of gene mutation on Salmonella bacterium growth rate

Most mutations in the genes of the Salmonella bacterium have a surprisingly small negative impact on bacterial fitness. And this is the case regardless whether they lead to changes in the bacterial proteins or not.

Study explains link between morbid obesity and metabolic syndrome

Scientists have found that the fat cells and tissues of morbidly obese people and animals can reach a limit in their ability to store fat appropriately. Beyond this limit several biological processes conspire to prevent further expansion of fat tissue and in the process may trigger other health problems.

Fearless behavior in children related to neurological and genetic predisposition

"The results of this study show that fearless behavior in children can be identified and is related to neurological and genetic predisposition. This type of behavior has less correlation - at least in infancy - with standards of educational processes or parenting practice," says Dr. Inbal Kivenson-Baron, who carried out the study.

New approach to treat castration resistant prostate cancer

A monoclonal antibody targeting a well known cell surface protein inhibited prostate cancer growth and metastasis in an aggressive form of the disease that did not respond to hormone therapy, according to a study by researchers with the UCLA Department of Urology and UCLA's Jonsson Comprehensive Cancer Center.

Genetic region linked to survival in patients with advanced bowel cancer

Scientists have discovered a genetic region linked to survival in patients with advanced bowel cancer, according to a study being presented at the National Cancer Research Institute (NCRI) Cancer Conference today (Tuesday).

EVP-6124 receptor acts as co-agonist with ACh to enhance cognition

EnVivo Pharmaceuticals today announced it has discovered that EVP-6124, its alpha-7 nicotinic acetylcholine receptor agonist, possesses a novel mechanism not previously seen in the scientific community: it acts as a co-agonist with Acetylcholine (ACh) to enhance cognition.

Study discovers role of Vav1 oncogene in several cancers

Researchers at the Hebrew University of Jerusalem have discovered that Vav1 - an oncogene (cancer-causing gene) found in recent years to be one of the factors in tumorous tissue growth -- plays a wider role in several types of cancer than had previously been thought. The discovery has implications for further concentration on targeting this gene in cancer research.

Scientists develop nanobioconjugate drug to target brain tumor

Nine years ago, scientists at Cedars-Sinai's Maxine Dunitz Neurosurgical Institute detected a subtle shift occurring in the molecular makeup of the most aggressive type of brain tumors, glioblastoma multiforme. With further study, they found that a specific protein called laminin-411 plays a major role in a tumor's ability to build new blood vessels to support its growth and spread. But technology did not exist then to block this protein.

Study confirms defect in sweat gland function as disease biomarker for XLHED

Edimer Pharmaceuticals, a biotechnology company focused on developing an innovative therapy for the rare genetic disorder, X-linked Hypohidrotic Ectodermal Dysplasia (XLHED), today announced key findings of a study exploring novel approaches to the assessment of sweat function in males with XLHED. Affected individuals lack a normal sweat response, placing them at life-long risk for clinically-significant hyperthermia.

Family history of HG increases risk of extreme morning sickness during pregnancy

Approximately 60,000 pregnant women are hospitalized each year due to hyperemesis gravidarum (HG), an extreme form of nausea and vomiting that endangers their lives and often forces them to reluctantly terminate their pregnancies.

Research on immune system may help in healing chronic inflammatory diseases

Biochemists at Kiel University, along with international scientists, have identified an important messenger in the immune system. The messenger interleukin-27 plays an important role when the human body blocks inflammations.

Study finds canola-type rapeseed oil decreases fibrinogen level

According to research on fatty acids conducted at the universities of Helsinki and Tampere, the consumption of canola-type rapeseed oil decreases the level of fibrinogen detrimental to health in the body. The increased fibrinogen level, caused by an imbalance in essential fats in one's diet, decreases when saturated fatty acids are replaced with rapeseed oil.

Research reveals EBV virus infected cell manipulates cancer-producing cells

A new discovery by UNC scientists describes how cells infected by the Epstein-Barr virus (EBV) produce small vesicles or sacs called exosomes, changing their cellular "cargo" of proteins and RNA. This altered exosome enters cells and can change the growth of recipient cells from benign to cancer-producing.

New COLD-PCR technology to detect EGFR gene mutation

Transgenomic, Inc. today announced completion of a development study of several new assays to detect genetic mutations using the Company's proprietary Co-amplification at Lower Denaturing Temperature PCR (COLD-PCR) technology in the Epidermal Growth Factor Receptor (EGFR) gene.

Excess levels of TNF immune signaling protein key factor in AD

Three new studies provide converging evidence pointing to a new therapeutic target in Alzheimer's Disease(AD). These studies, from independent academic centers in the U.S., England, and China, point to excess levels of a protein called TNF as a key factor in AD. TNF is an immune signaling protein that regulates both inflammation and neuronal communication in the brain.
