From HIV to cancer, IL-37 regulates immune system

“Knowing this mechanism that underlies IL-37’s effect on the immune system now allows us to study IL-37 function and perhaps dysfunction in a wide range of diseases,” says Mayumi Fujita, MD, PhD, investigator at the University of Colorado Cancer Center, associate professor in the CU School of Medicine Department of Dermatology, and the paper’s senior author. For example, knowing that IL-37 helps to create overall immune system sensitivity could allow researchers to manipulate IL-37 levels to sensitize the immune system to recognize and target tumor tissue, or desensitize the immune system in auto-immune conditions like rheumatoid arthritis in which the immune system acts over-aggressively toward healthy tissue. …

Viewing cancer on the move: New device yields close-up look at metastasis

The inventors, from the university’s Whiting School of Engineering and its Institute for NanoBioTechnology (INBT), published details and images from their new system recently in the journal Cancer Research. Their article reported on successful tests that captured video of human breast cancer cells as they burrowed through reconstituted body tissue material and made their way into an artificial blood vessel. “There’s still so much we don’t know about exactly how tumor cells migrate through the body, partly because, even using our best imaging technology, we haven’t been able to see precisely how these individual cells move into blood vessels,” said Andrew D. …

Clock gene dysregulation may explain overactive bladder — ScienceDaily

“We hope our study will stimulate further progress in understanding circadian control of body physiology and aging-related dysfunction and ultimately lead to new strategies of treatment by targeting the circadian regulatory process, including non-drug treatment approaches,” said Changhao Wu, M.D., Ph.D., a researcher involved in the work from the Department of Biochemistry and Physiology at the University of Surrey in the United Kingdom. To make this discovery, scientists used genetically modified mice in which a special wavelength of light was emitted when the clock proteins were produced in isolated bladder tissue. This light reported real-time clock expression and acted directly as a measure of peripheral clock expression…

Potential target for treating triple-negative breast cancer identified — ScienceDaily

So-called “triple-negative” breast cancer represents between 12 and 17 percent of all breast cancers. It derives its name from the lack of receptors for estrogen, progesterone and Her2…

Different brain tumors have the same origin, new findings show

The most common primary, malignant brain tumors in adults, called glioma, are formed from cells in the brain that are not nerve cells. These are serious tumors that lack efficient treatment and relapses are common. There are different types of glioma, classified according to an established system based on which cell type the tumor arises from. The most common gliomas are astrocytoma, which have their name from astrocytes, and oligodendroglioma, which are believed to arise from oligodendrocytes. …

Potential target for treating triple-negative breast cancer identified

So-called “triple-negative” breast cancer represents between 12 and 17 percent of all breast cancers. It derives its name from the lack of receptors for estrogen, progesterone and Her2. The absence of these receptors rules out proven hormone therapies such as tamoxifen. …

Scientists generate first human stomach tissue in lab with stem cells

Scientists at Cincinnati Children’s Hospital Medical Center report Oct. 29 in Nature they used human pluripotent stem cells — which can become any cell type in the body — to grow a miniature version of the stomach…

Mushroom extract, AHCC, helpful in treating HPV

The results were presented at the 11th International Conference of the Society for Integrative Oncology in Houston today by principal investigator Judith A. Smith, Pharm.D., associate professor in the Department of Obstetrics, Gynecology and Reproductive Sciences at the UTHealth Medical School. Ten HPV-positive women were treated orally with the extract, AHCC (active hexose correlated compound) once daily for up to six months…

Tea, citrus products could lower ovarian cancer risk, new research finds

The research reveals that women who consume foods containing flavonols and flavanones (both subclasses of dietary flavonoids) significantly decrease their risk of developing epithelial ovarian cancer, the fifth-leading cause of cancer death among women. The research team studied the dietary habits of 171,940 women aged between 25 and 55 for more than three decades. The team found that those who consumed food and drinks high in flavonols (found in tea, red wine, apples and grapes) and flavanones (found in citrus fruit and juices) were less likely to develop the disease. Ovarian cancer affects more than 6,500 women in the UK each year…

Anti-cancer drug effective against common stem cell transplant complication

“Bortezomib helped a group of patients who desperately needed a treatment, having failed multiple different therapies,” said UC Davis hematologist and associate professor Mehrdad Abedi, lead author on the paper. “The drug fights chronic graft-versus host disease, and unlike other GVHD therapies such as steroid, cyclosporine or mycophenolate, it treats chronic GVHD without dampening the graft-versus-tumor effect, which can be critically important to help patients avoid relapse. In fact, because bortezomib is an anti-cancer drug, it potentially attacks cancer cells in its own right.” The trial results were published in October in the journal Blood. Chronic GVHD strikes patients who have received stem cell transplants from donors, commonly called allogeneic transplants. …
