Cancer-fighting therapy shows promise as treatment to speed up wound healing

A type of targeted therapy that has shown promising results treating advanced melanoma could also be used to help speed up how the skin repairs itself from injury, UCLA researchers have found, providing a potential new way to accelerate healing of acute and chronic wounds. In the United States alone, chronic wounds affect more than 6.5 million people and an estimated $50 billion is spent annually treating these conditions. Many areas of medicine — from improving recovery times after surgery to reducing skin-related secondary effects of cancer treatments and other diseases — can benefit from speeding up the skin’s healing process. Aiming to meet this urgent and unmet need, the UCLA researchers investigated a new class of cancer therapy called BRAF inhibitors. These drugs work by blocking a mutated gene in melanoma, which rapidly shrinks the tumor. This can set off a cellular cascade in other skin cells in a process called paradoxical MAPK activation, which can lead to a variety of skin-related side effects, said Dr. Antoni Ribas, director of the UCLA Jonsson Comprehensive Cancer Center Tumor Immunology Program and senior author of the study. “We set out to take advantage of our mechanistic understanding of these drugs and see if we could turn a side effect into a potentially beneficial effect,” Ribas said. “These agents have great potential to be used to develop topical treatments to greatly accelerate wound healing.” The three-year st...

In this study, we compared the long-term side effects of proton radiation to equivalent doses of X-rays in the initiation and progression of premalignant lesions in a lung cancer susceptible mouse model (K-rasLA1). We show proton irradiation causes more complex DNA damage that is not completely repaired resulting in increased oxidative stress in the lungs both acutely and persistently. We further observed K-rasLA1 mice irradiated with protons had an increased number and size of initiated and premalignant lesions and adenomas that were often infiltrated with inflammatory cells. Proton irradiated mice had a lower median surv...

It is known that in these disorders the fatty acid metabolism is impaired. The aim of this study was to compare the fatty acid profile in the heart and renal transplant recipients who developed metabolic disorders since there is no such research available.Materials and methodsThe study included 55 patients...

In this study, we have shown that NOL8, a binding protein of beta-catenin, enhanced the interaction between beta-catenin and TCF4, and activated beta-catenin/TCF signaling. NOL8 is up-regulated in the prostate cancer, and promoted the growth, migration and colony formation of cancer cells. Knocking down the expression of NOL8 inhibited the growth, migration and colony formation of prostate cancer cells. The molecular mechanism study demonstrated that NOL8 promoted the migration and colony formation of cancer cells by activating beta-catenin/TCF signaling. Taken together, this study demonstrated the oncogenic roles of NOL8 ...

Jang, Dae Won Park, Eun Hwa Shon, Sung Ryul Lee, Se Chan KangAbstractVascular inflammation has been suggested to play a key role in the initiation and progression of atherosclerosis. Hyperoside (HPS) is a plant-derived quercetin 3-d-galactoside reported to have anti-inflammatory, anti-oxidant, anti-cancer, anti-hyperglycemic, anti-coagulant, and cardioprotective activities. However, the effects of HPS on vascular inflammation have not been studied. Therefore, in this study, we investigated the suppressive effect of HP...

To achieve these goals, developing drug delivery systems is the key step. The common materials used for drug delivery like liposomes, micelles, dendrimers cannot control the delivery and releasing by spatial and temporal. In this paper, we design a photoresponsive drug delivery system to reduce the side effects of traditional chemotherapy on normal cells and improve...

Authors: Zhang S, Cai J, Xie W, Luo H, Yang F Abstract MicroRNA (miR)-202 has been reported to be involved in the regulation of human cancer progression including bladder cancer, non-small cell lung cancer, pancreatic cancer and esophageal squamous cell carcinoma. However, the function of miR-202 in prostate cancer remains largely unknown. The present study demonstrated that miR-202 was downregulated in human prostate cancer tissues and cell lines. And overexpression of miR-202 significantly inhibited the proliferation, migration and invasion of prostate cancer cells, but induced cell apoptosis. Moreover, miR-202 s...

Authors: Hao B, Chen X, Cao Y Abstract Yes-associated protein 1 (YAP1) is overexpressed in a number of human cancer types as an oncogene and takes part in processes of tumor cell proliferation, apoptosis and metastasis. The Notch pathway also has an important role in tumorigenesis and progression. However, the possible association between YAP1 and Notch signaling in glioma has remained to be determined. The present study verified the high expression of YAP1, Jagged 1 (JAG1), NOTCH1 and HES1 in the U251 glioma cell line via reverse-transcription quantitative polymerase chain reaction and western blot analysis. The e...

Abstract Longer lifespan is accompanied by a larger number of chronic diseases among older adults. Because of a growing proportion of older adults in the U.S., this brings the problem of age-related morbidity to the forefront as a major contributor to rising medical expenditures. We evaluated 15-year time trends (from 1998 to 2013) in the prevalence of 48 acute and chronic non-cancer diseases and cancers in older U.S. adults aged 65+ and estimated the annual percentage changes of these prevalence trends using SEER-Medicare and HRS-Medicare data. We found that age-adjusted prevalence of cancers of kidney, pancreas,...
