Researchers hope the finding leads to new treatments and ways to identify aneurysms early.<\/div>\n<div style=\"margin: 0in 0in 0pt\">&nbsp;<\/div>\n<div style=\"margin: 0in 0in 0pt\">Timothy Baxter, M.D., professor. and Wanfen Xiong, M.D., Ph.D., assistant professor, led a team that published the findings in the Jan. 16 edition of the Journal of Biological Chemistry.<\/div>\n<div style=\"margin: 0in 0in 0pt\">&nbsp;<\/div>\n<div style=\"margin: 0in 0in 0pt\">A product of macrophages, the enzyme, MT1-MMP, is released at injury sites to help the healing process. But, when diseases exist such as atherosclerosis, the enzymes may be released over a prolonged period of time and actually become part of the disease process. &nbsp;Drs. Xiong and Baxter found that MT1-MMP degrades the protein elastin in the vessel wall, leaving it brittle like a stretched-out rubber band.<\/div>\n<div style=\"margin: 0in 0in 0pt\">&nbsp;<\/div>\n<div style=\"margin: 0in 0in 0pt\">&ldquo;The artery bulges and cannot come back to its original shape,&rdquo; Dr. Xiong said.<\/div>\n<div style=\"margin: 0in 0in 0pt\">&nbsp;<\/div>\n<div style=\"margin: 0in 0in 0pt\">An aortic aneurysm is an abnormal bulge or &quot;ballooning&quot; in the wall of an artery, which may burst from the weakening of the vessel wall. Currently, the only way to treat aortic aneurysms is by surgical intervention. Drs. Xiong and Baxter research ways to detect aneurysms earlier and treat them with drugs before surgical repair is necessary.<\/div>\n<div style=\"margin: 0in 0in 0pt\">&nbsp;<\/div>\n<div style=\"margin: 0in 0in 0pt\">Their research is funded by a $1.5 million grant from the U.S. Department of Health and Human Services. They are seeking a renewal to continue this research<\/div>\n<div style=\"margin: 0in 0in 0pt\">&nbsp;<\/div>\n<div style=\"margin: 0in 0in 0pt\">&ldquo;Our goal is to develop medical treatments for small aneurysms, as well as markers to identify them at earlier stages,&quot; Dr. Baxter said. &quot;Doing that would lower the anxiety levels of patients with small, but growing aneurysms and improve the medical outcomes of this common and potentially deadly disease.&rdquo;<\/div>\n<div style=\"margin: 0in 0in 0pt\">&nbsp;<\/div>\n<div style=\"margin: 0in 0in 0pt\">The research has applications such as emphysema, skin diseases, arthritis and dementia, Dr. Baxter said.<\/div>\n<div style=\"margin: 0in 0in 0pt\">&nbsp;<\/div>\n<div style=\"margin: 0in 0in 0pt; text-indent: 0.5in\"><i><span style=\"font-size: 9pt; color: black\">UNMC is the only public health science center in the state. Its educational programs are responsible for training more health professionals practicing in Nebraska than any other institution. Through their commitment to education, research, patient care and outreach, UNMC and its hospital partner, The Nebraska Medical Center, have established themselves as one of the country&#8217;s leading centers in cancer, transplantation biology, bioterrorism preparedness, neurodegenerative diseases, cardiovascular diseases, genetics, biomedical technology and ophthalmology. UNMC&rsquo;s research funding from external sources now exceeds $82 million annually and has resulted in the creation of more than 2,400 highly skilled jobs in the state. UNMC&#8217;s physician practice group, UNMC Physicians, includes 513 physicians in 50 specialties and subspecialties who practice primarily in The Nebraska Medical Center.
