One-two punch of drugs better than either alone against colorectal cancer

Of course, researchers have extensively targeted these two signaling pathways, designing drugs that turn on or off genes in these pathways, thus interrupting the transmission of cancer-causing signals. Unfortunately, these pathways have proven difficult to drug and also it has been difficult to show the effectiveness of drugs that successfully interrupt the transmission of signals along these pathways. A study by the University of Colorado Cancer Center published in the journal PLoS ONE and concurrent phase I clinical trial is examining a new strategy: targeting both these important cancer-causing pathways simultaneously. “Well, these two pathways are mutated frequently in cancer. …

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. …

Ebola highlights disparity of disease burden in developed vs. developing countries

“Our goal is to provide information about trends and patterns to bring to light what’s going on around the world so that funds can be allocated and policy developed as needed,” says Lindsay Boyers, medical student at Georgetown University, working in the lab or Robert Dellavalle, MD, PhD, MSPH investigator at the University of Colorado Cancer Center, associate professor of dermatology at the University of Colorado School of Medicine, and the paper’s senior author. The paper used data from the Global Burden of Disease Study, an ongoing project funded by the Bill and Melinda Gates Foundation to collect a billion data points describing the distribution of the world’s diseases. Of the 269 diseases in the GBD database, this study compares rates in developed versus developing countries of Ebola, malignant melanoma, basal and squamous cell carcinoma, decubitus ulcer, bacterial skin diseases, cellulitis, varicella (including chickenpox, congenital varicella infection, and herpes zoster), syphilis, measles, and dengue. Specifically, findings show that in 2010 the measles death rate was 197 times greater in developing countries than in developed countries, but this ratio was down from 345-to-1 in 1990. …

Diverse gut bacteria associated with favorable ratio of estrogen metabolites

Since the 1970s, it has been known that in addition to supporting digestion, the intestinal bacteria that make up the gut microbiome influence how women’s bodies process estrogen, the primary female sex hormone. The colonies of bacteria determine whether estrogen and the fragments left behind after the hormone is processed continue circulating through the body or are expelled through urine and feces. Previous studies have shown that levels of estrogen and estrogen metabolites circulating in the body are associated with risk of developing postmenopausal breast cancer…

‘Treatments waiting to be discovered’ inside new database

“You can’t imagine the tangled web of data that describes the cause and effect relationships of microRNAs and genes. This multiMiR database will let researchers search efficiently through these relationships for pairings relevant to the diseases they study,” says Katerina Kechris, PhD, associate professor of Biostatistics and Informatics at the University of Colorado Denver, and one of the study’s senior authors. In addition to assisting researchers search for relationships between microRNAs and their genetic targets, the database includes drugs known to affect these microRNAs and also lists diseases associated with microRNAs. “Right now, within this database, investigators can find clues to potential new treatments for various diseases including cancer,” says Dan Theodorescu, MD, PhD, professor of Surgery and Pharmacology at the CU School of Medicine, director of the University of Colorado Cancer Center and one of the study’s senior authors. …
