Transgenic mice to visualize metastasis and inflammation

One of the major routes of tumor cell dissemination to form metastasis at distant organs in the body is the lymphatic system. To study this process, still poorly understood, and to gain information on which tumors prefer this route for dissemination and how to block it, researchers of the Spanish National Cancer Research Center, led by researcher Sagrario Ortega, have created transgenic mice in which, for the first time, the growth of the lymphatic vessels can be visualized in the whole animal, by a light-emitting reaction, as tumor progresses and forms metastasis.

Insight into relationship between two types of suppressors in cancerous tumors

The University of Kentucky has announced that Dr. Daret St. Clair, the James Graham Brown Endowed Chair and professor of toxicology, has published the first comprehensive study that provides insight into the relationship between two types of suppressors in cancerous tumors. The results will enhance the understanding of transcriptional mechanisms in carcinogenesis.

MV-GFP extends survival of animals with medulloblastoma

A strain of measles virus engineered to kill cancer cells prolongs survival in a model of medulloblastoma that is disseminated in the fluid around the brain, according to a new study by researchers at Ohio State University Comprehensive Cancer Center - Arthur G. James Cancer Hospital and Richard J. Solove Research Institute and the Mayo Clinic.

Study reveals possibility to selectively target and block crucial microRNA in liver cancer

A new study shows that it is possible to selectively target and block a particular microRNA that is important in liver cancer. The findings might offer a new therapy for this malignancy, which kills an estimated 549,000 people worldwide annually.

NYUCI experts present latest research findings about hematologic cancers at 53rd ASH meeting

Experts from the NYU Cancer Institute, an NCI-designated cancer center at NYU Langone Medical Center, presented their latest research findings about hematologic cancers at the 53rd ASH Annual Meeting and Exposition held December 10-13, 2011 in San Diego, California.

Scientists show how RET gene in breast cancer cells responds to estrogen

Using human breast cancer cells and the protein that causes fireflies to glow, a Johns Hopkins team has shed light on why some breast cancer cells become resistant to the anticancer effects of the drug tamoxifen. The key is a discovery of two genetic "dimmer switches" that apparently control how a breast cancer gene responds to the female hormone estrogen.

Reprogrammed herpes virus can improve early cancer diagnosis

Scientists have used a genetically re-engineered herpes virus that selectively hunts down and infects cancerous tumors and then delivers genetic material that prompts cancers to secrete a biomarker and reveal their presence.

Pervasis' PVS-30200 study data in prostate cancer presented at AACR meeting

Pervasis Therapeutics, Inc. today announced preclinical data showing positive effects of PVS-30200, the company's investigational cell therapy for the treatment of solid tumors, on controlling tumor growth and inhibiting metastases in an animal model of prostate cancer.

Research shows how tubercle bacterium manages to survive inside body's macrophage cells

Tuberculosis kills two million people each year and is once again gaining ground also in Sweden and other Western countries. Researchers at Linköping University in Sweden are now presenting new findings that show how the tubercle bacterium manages to survive inside the body's macrophage cells in order eventually to blow them up and spread their infection.

Luciferase enzyme offers promise for improved monitoring of heparin therapy: New study

The enzyme that makes fireflies glow is lighting up the scientific path toward a long-sought new medical imaging agent to better monitor treatment with heparin, the blood thinner that millions of people take to prevent or treat blood clots, scientists are reporting. Their study appears in the ACS' monthly journal Bioconjugate Chemistry.

Fungus may provide clue about human response to changes in circadian rhythm

Humans are not the only species ruled by a circadian rhythm. Even simple organisms like moulds are governed by an inner clock. Studying red bread mould may teach us how our own internal clock works. This is exactly what the Centre for Organelle Research at the University of Stavanger, Norway is doing.

PEG-Prom encased nanoparticle aids in cancer detection and treatment

In a proof of principal study in mice, scientists at Johns Hopkins and the Virginia Commonwealth University have shown that a set of genetic instructions encased in a nanoparticle can be used as an "ignition switch" to rev up gene activity that aids cancer detection and treatment.

New stem cell-infused patch improves heart function after myocardial infarction

University of Cincinnati (UC) researchers have found that applying a stem cell-infused patch together with overexpression of a specific cell instruction molecule promoted cell migration to damaged cardiac tissue following heart attack and resulted in improved function in animal models.

Researchers shed new light about long non-coding RNA molecules

Despite progress in decoding the genome, scientists estimate that fully 95 percent of our DNA represents dark, unknown territory. In the October 1 issue of the journal Cell researchers at The Wistar Institute shed new light on the genetic unknown with the discovery of the ability of long non-coding RNA (ncRNA) to promote gene expression.

Scientists develop laser activated carbon nanoparticles for drug, gene delivery

Using chemical "nanoblasts" that punch tiny holes in the protective membranes of cells, researchers have demonstrated a new technique for getting therapeutic small molecules, proteins and DNA directly into living cells.Carbon nanoparticles activated by bursts of laser light trigger the tiny blasts, which open holes in cell membranes just long enough to admit therapeutic agents contained in the surrounding fluid. By adjusting laser exposure, the researchers administered a small-molecule marker compound to 90 percent of targeted cells - while keeping more than 90 percent of the cells alive.
