Cancer drug could treat blood vessel deformities
A drug currently being trialled in cancer patients could also be used to treat an often incurable condition that can cause painful blood vessel overgrowths inside the skin, finds new research in mice led by UCL, Memorial Sloan Kettering Cancer Center in New York and the Bellvitge Biomedical Research Institute in Barcelona. The findings are published in two independent but complementary papers in Science Translational Medicine, led by UCL and MSK respectively.

Statement published on pairing smoking cessation with lung cancer screening
Smokers who are screened for lung cancer should be encouraged to quit smoking during their visit, according to a paper co-written by Benjamin A. Toll, Ph.D., of the Medical University of South Carolina. Citing the recent USPTF recommendation that heavy smokers undergo a yearly screening for lung cancer, the authors note USPTF does not provide specifics for how smoking-cessation treatment should be offered in conjunction with screenings. The article, published in Cancer, addresses specific recommendations.

Another reason to break the habit: Smoking alters bacterial balance in mouth
Smoking drastically alters the oral microbiome, the mix of roughly 600 bacterial species that live in people's mouths. This is the finding of a study led by NYU Langone Medical Center and its Laura and Isaac Perlmutter Cancer Center to be published online March 25 in the ISME (International Society for Microbial Ecology) Journal.

CWRU researchers make biosensor 1 million times more sensitive
To provide oncologists a way to detect a single molecule of an enzyme produced by circulating cancer cells, physicists and engineers at Case Western Reserve University have developed an optical sensor, based on nanostructured metamaterials, that's 1 million times more sensitive than the current best available. The device proved capable of identifying a single lightweight molecule in a highly dilute solution.

New target makes end run against therapy-resistant prostate cancer

How cancer stem cells thrive when oxygen is scarce
Working with human breast cancer cells and mice, scientists at the Johns Hopkins University say new experiments explain how certain cancer stem cells thrive in low oxygen conditions. Proliferation of such cells, which tend to resist chemotherapy and help tumors spread, are considered a major roadblock to successful cancer treatment.

Penn studies show high out-of pocket costs limit access to lifesaving specialty drugs
Specialty drugs have become important treatment options for many serious and chronic diseases, and in some conditions like cancer they represent the only chance for long-term survival. But, insurers increasingly require patients to share the high costs of these medications. Two new studies led by researchers at Penn have found evidence that such cost-sharing arrangements are associated with significant reductions in access to these drugs.

BIDMC researchers discover early indicators of pancreatic cancer
Pancreatic cancer, the fourth leading cause of cancer death in the United States, is often diagnosed at a late stage, when curative treatment is no longer possible. A team led by investigators at Beth Israel Deaconess Medical Center has now identified and validated an accurate 5-gene classifier for discriminating early pancreatic cancer from non-malignant tissue. Described online in the journal Oncotarget, the finding is a promising advance in the fight against this typically fatal disease.

Solved: First crystal structure of a transcription terminator protein
Researchers at the Medical University of South Carolina and elsewhere resolve the first protein structure in a family of proteins called transcription terminators that could provide insight into aging and cancer. The work reveals the protein Reb1 to be a traffic signal for coordinating transcription and gene replication, rather than a passive roadblock as previously thought.

Researchers identify SH2 domains as lipid-binding modules for cell signaling
Majority of human Src homology 2 domains not only bind to proteins, but also interact with membrane lipids with high affinity and specificity. The SH2 domain-containing proteins play important roles in various physiological processes and are involved in cancer development. This study reveals how lipids control SH2 domain-mediated cellular protein interaction networks and suggests a new strategy for the therapeutic modulation of pY-signaling pathways.

Study shows that Wnt secretion preventing drugs may reduce renal fibrosis
Renal fibrosis or the scarring of kidneys, following an injury, reduces their function and can cause kidney disease to progressively worsen. In a recent study, published in Kidney International, researchers from Duke-NUS Medical School (Duke-NUS) in Singapore and Duke University have shown that drugs that target Wnt secretion by inhibiting Porcupine, a protein usually targeted for cancer treatment, may reduce renal fibrosis and protect the kidneys.

Potential for misuse & diversion of opioids to addicts should not overshadow their therapeutic value
Opioids are very effective for treating some types of pain, such as cancer pain and postoperative pain, but not for other kinds of pain like chronic low back pain. An increase in the number of opioid-related deaths among addicts has led to the current movement to restrict opioid prescribing by state and federal authorities. While a laudable goal, these restrictions threaten to block their use for safe and effective pain relief when medically indicated.
