NVCI, CSN and Workforce CONNECTIONS partner to launch ARRA funded nursing internship program

Nevada Cancer Institute (NVCI) is launching its Plus One Program, a paid nursing internship initiative to equip nursing graduates with advanced training to give them an edge in today's competitive nursing job market. After completing a paid one-year internship at NVCI, participants will become oncology nurses, a highly sought-after specialty. These specialized jobs have the potential to pay increased wages, provide excellent benefits and support articulated career ladders within the field of oncology.

Researchers find that increase in leptin may promote colorectal neoplasms

Now, for the first time, a collaborative study of researchers at the Sbarro Institute for Cancer Research and Molecular Medicine at Temple University's College of Science and Technology and the Department of Hematology, Oncology and Molecular Medicine, Istituto Superiore di Sanità, Rome, Italy have found that an increase in leptin, a cytokine that is normally increased in obese or overweight individuals, may promote colorectal neoplasms by activating colorectal cancer stem cells.

Resveratrol concentration impacts cancer risk mitigation: Study

Agricultural Research Service (ARS) chemist Thomas Wang, who specializes in cancer prevention research, has reported evidence that for some dietary compounds, length of exposure over time may be key to whether or not ingestion leads to a beneficial, or detrimental, effect.Scientists do not know exactly why one person develops cancer and another does not. But they do know that certain nutrients might increase or decrease cancer risk. There are "layers" of factors involved in the development of cancer, and Wang is studying the layers involving peoples' diet complexity and gene expression.

Improved delivery methods needed to advance gene therapy strategies for prostate cancer: Review

Improved delivery methods and better testing systems are needed to advance promising gene therapy strategies for treating prostate cancer, according to a series of review articles in Human Gene Therapy, a peer-reviewed journal published by Mary Ann Liebert, Inc.

Plant extract effective against ulcerative colitis in mice

A South Dakota State University scientist's research shows an extract made from a food plant in the Brassica family was effective in alleviating signs of ulcerative colitis, an inflammatory bowel condition, in mice.

Olive oil, Mediterranean diet modify expression of atherosclerosis-related genes

Everyone knows olive oil and a Mediterranean diet are associated with a lower risk for cardiovascular disease, but a new research report published in the July 2010 print issue of the FASEB Journal offers a surprising reason why: These foods change how genes associated with atherosclerosis function.

Key mechanism present in virgin olive oil protects body against breast cancer: Researchers

Researchers at Universitat Autònoma de Barcelona, led by Dr Eduard Escrich, have discovered a key mechanism by which virgin olive oil, in contrast to other vegetable oils, protects the body against breast cancer.

Hydrophobic proteins may serve as biomarkers for treating colorectal cancer

Colorectal cancer, cancer of the colon and rectum, is a common cause of mortality worldwide. Statistical data showed that the number of deaths caused by colorectal cancer is increasing in both men and women.

Researchers describe carcinogenic effects of EDCs

Longtime environmental health researchers at Tufts University School of Medicine describe the carcinogenic effects of endocrine-disrupting chemicals, ubiquitous chemicals that have hormone-like effects in the body. In a review article published online May 25 in Nature Reviews Endocrinology, the researchers express the need for more complex strategies for studying how these chemicals affect health but report that ample evidence already supports changing public health and environmental policies to protect the public from exposure to EDCs.

Researchers discover biological pathway signature of ccRCC

By examining expression of every human gene in clear cell renal cell carcinoma compared to normal kidney cells, researchers at Mayo Clinic's campus in Florida have discovered gene signatures they say explain much of the biology of this common and difficult-to-treat kidney cancer.

Study examines impact of tobacco smoke carcinogen on mice

Although tobacco use is widely understood to be one of the leading causes of oral cancer, research on the prevention of tobacco-related oral cancer in experimental animals has traditionally been limited to examining the impact of synthetic carcinogens manufactured especially for cancer research, rather than on observing the effects of carcinogens that occur in tobacco smoke.

Research investigates MDR in human HCC

Hepatocellular carcinoma responds poorly to chemotherapy owing to MDR. Recent studies have shown the tumors derived from the colon, kidney, or adrenal cortex, and HCC exhibited overexpression of MDR1/P-gp. This overexpression results in a primary MDR phenotype of these cancers.

Researchers investigate aberrant expression of nuclear matrix proteins in gastric cancer cells

Gastric cancer is the most common malignant gastrointestinal cancer and accounts for 25% of cancer deaths. Nuclear matrix, a filamentous protein framework for eukaryotic cellular chromatin, closely relates to DNA duplication and transcription. Research on nuclear matrix proteins will provide insight into how tumors developed.

UVA exposure at early age does not cause melanoma

Early life exposure to ultraviolet A light does not cause melanoma in a fish model that previously made that connection, scientists from The University of Texas MD Anderson Cancer Center reported today in the online Early Edition of the Proceedings of the National Academy of Sciences.

Adjuvant chemotherapy after gastric cancer procedure may reduce mortality

Patients who have gastric cancer surgery followed by chemotherapy have an associated decreased risk of death and improved disease-free survival compared to patients who have surgery alone, according to an analysis of previous studies, reported in the May 5 issue of JAMA.

A new approach for treating neurological and degenerative disorders

In studies on cancer, heart disease, neurological disorders and other degenerative conditions, some scientists are moving away from the "nature versus nurture" debate, and are finding you're not a creature of either genetics or environment, but both - with enormous implications for a new approach to health.

COX-2 expression not an adequate independent prognostic factor: Research

Cyclooxygenase-2 represents a key modulatory molecule in inflammation and carcinogenesis. COX-2 is known to have multiple tumorigenic effects. Increased expression of COX-2 has been observed in a variety of tumors including pancreatic cancer.

LSF gene plays important role in development and progression of HCC: VCU researchers

Virginia Commonwealth University researchers have identified a new tumor-promoting gene that may play a key role in the development of liver cancer. Levels of the gene's expression are significantly higher in more than 90 percent of patients with the disease compared to their healthy counterparts.

Research shows association between LRP16 expression in colorectal cancer and disease related death

Leukemia related protein 16 gene is an important estrogen-responsive gene. LRP16 gene plays an important role in the carcinogenesis and progression of hormone-dependent cancer. LRP16 expression was also reported to be associated with invasion, metastasis and prognosis of gastric carcinoma. But no comprehensive description of LRP16 protein expression in colorectal cancer has been reported.

Gamma-tocotrienol kills prostate tumour cells in animal model studies

Researchers from Davos Life Science in Singapore, in collaboration with scientists at the University of Hong Kong, have shown that gamma-tocotrienol, a member of the vitamin E family, is potent in killing prostate tumour cells in animal model studies. This research was reported this week in the latest edition of Pharmacology.
