Steady Increment Of Immature Platelet Fraction Is Suppressed By Irradiation In Single-Donor Platelet Components During Storage, Hong Hong, Wenbin Xiao, Robert W. Maitta

Faculty Scholarship

Circulating immature platelet fraction (IPF) reflects real-time thrombopoiesis and correlates with platelet recovery from thrombocytopenic presentations. To understand the dynamics of IPF in platelet transfusions, we quantified the %-IPF in single-donor platelet components (SDP) during prolonged storage. %-IPF significantly increased from baseline by day 5 post-donation. Absolute IPF counts (A-IPC) had similar significant increments. However, gamma-irradiation suppressed the increments of %-IPF and A-IPC by >50%. Ultrastructural analysis of SDP units at day 10 showed well preserved morphology of immature platelets. Our findings suggest that IPF might actively expand ex-vivo and may have a longer shelf life than their mature counterparts. …

The Emerging Role Of Oxylipins In Thrombosis And Diabetes., Benjamin E Tourdot, Intekhab Ahmed, Michael Holinstat

Division of Endocrinology, Diabetes and Metabolic Diseases Faculty Papers

The prevalence of cardiovascular disease (CVD), the leading cause of death in the US, is predicted to increase due to the shift in age of the general population and increase in CVD risk factors such as obesity and diabetes. New therapies are required to decrease the prevalence of CVD risk factors (obesity and diabetes) as well as reduce atherothrombosis, the major cause of CVD related mortality. Oxylipins, bioactive metabolites derived from the oxygenation of polyunsaturated fatty acids, play a role in the progression of CVD risk factors and thrombosis. Aspirin, a cyclooxygenase-1 inhibitor, decreases atherothrombotic associated mortality by 25%. These …

The Role Of Bioactive Lipids In Stem Cell Mobilization And Homing: Novel Therapeutics For Myocardial Ischemia, Yuri M. Klyachkin, Anush V. Karapetyan, Mariusz Z. Ratajczak, Ahmed Abdel-Latif

Saha Cardiovascular Research Center Faculty Publications

Despite significant advances in medical therapy and interventional strategies, the prognosis of millions of patients with acute myocardial infarction (AMI) and ischemic heart disease (IHD) remains poor. Currently, short of heart transplantation with all of its inherit limitations, there are no available treatment strategies that replace the infarcted myocardium. It is now well established that cardiomyocytes undergo continuous renewal, with contribution from bone marrow (BM)-derived stem/progenitor cells (SPCs). This phenomenon is upregulated during AMI by initiating multiple innate reparatory mechanisms through which BMSPCs are mobilized towards the ischemic myocardium and contribute to myocardial regeneration. While a role for the SDF-1/CXCR4 …

Soluble Apoe/Aβ Complex: Mechanism And Therapeutic Target For Apoe4-Induced Ad Risk, Leon M. Tai, Shipra Mehra, Varsha Shete, Steven Estus, G. William Rebeck, Guojun Bu, Mary Jo Ladu

Sanders-Brown Center on Aging Faculty Publications

The APOE4 allele of apolipoprotein E (apoE) is the greatest genetic risk factor for Alzheimer's disease (AD) compared to APOE2 and APOE3. Amyloid-β (Aβ), particularly in a soluble oligomeric form (oAβ), is considered a proximal cause of neurodegeneration in AD. Emerging data indicate that levels of soluble oAβ are increased with APOE4, providing a potential mechanism of APOE4-induced AD risk. However, the pathway(s) by which apoE4 may increase oAβ levels are unclear and the subject of continued inquiry. In this editorial review, we present the hypothesis that apoE isoform-specific interactions with Aβ, namely apoE/Aβ complex, modulate Aβ levels. Specifically, we …

Metabotropic Glutamate Receptor-1 Contributes To Progression In Triple Negative Breast Cancer, Malathi Banda, Cecilia L. Speyer, Sara N. Semma, Kingsley O. Osuala, Nicole Kounalakis, Keila E.

TNBC is an aggressive breast cancer subtype that does not express hormone receptors (estrogen and progesterone receptors, ER and PR) or amplified human epidermal growth factor receptor type 2 (HER2), and there currently exist no targeted therapies effective against it. Consequently, finding new molecular targets in triple negative breast cancer (TNBC) is critical to improving patient outcomes. Previously, we have detected the expression of metabotropic glutamate receptor-1 (gene: GRM1; protein: mGluR1) in TNBC and observed that targeting glutamatergic signaling inhibits TNBC growth both in vitro and in vivo. In this study, we explored how mGluR1 contributes to TNBC …

An effective way to reduce LDL cholesterol, the primary risk factor of atherosclerotic cardiovascular disease, is to increase cholesterol excretion from the body. Our group and others have recently found that cholesterol excretion can be facilitated by both hepatobiliary and transintestinal pathways. However, the lipoprotein that moves cholesterol through the plasma to the small intestine for transintestinal cholesterol efflux (TICE) is unknown. To test the hypothesis that hepatic very low-density lipoproteins (VLDL) support TICE, antisense oligonucleotides (ASO) were used to knockdown hepatic expression of microsomal triglyceride transfer protein (MTP), which is necessary for VLDL assembly. While maintained on a high …

Aortic Aneurysms In Loeys-Dietz Syndrome - A Tale Of Two Pathways?, Frank Davis, Debra L. Rateri, Alan Daugherty

Saha Cardiovascular Research Center Faculty Publications

Loeys-Dietz syndrome (LDS) is a connective tissue disorder that is characterized by skeletal abnormalities, craniofacial malformations, and a high predisposition for aortic aneurysm. In this issue of the JCI, Gallo et al. developed transgenic mouse strains harboring missense mutations in the genes encoding type I or II TGF-β receptors. These mice exhibited several LDS-associated phenotypes. Despite being functionally defective, the mutated receptors enhanced TGF-β signaling in vivo, inferred by detection of increased levels of phosphorylated Smad2. Aortic aneurysms in these LDS mice were ablated by treatment with the Ang II type 1 (AT1) receptor antagonist losartan. The results from this …

Pb Neurotoxicity: Neuropsychological Effects Of Lead Toxicity, Lisa H. Mason, Jordan P. Harp, Dong Y. Han

Neurology Faculty Publications

Neurotoxicity is a term used to describe neurophysiological changes caused by exposure to toxic agents. Such exposure can result in neurocognitive symptoms and/or psychiatric disturbances. Common toxic agents include heavy metals, drugs, organophosphates, bacterial, and animal neurotoxins. Among heavy metal exposures, lead exposure is one of the most common exposures that can lead to significant neuropsychological and functional decline in humans. In this review, neurotoxic lead exposure's pathophysiology, etiology, and epidemiology are explored. In addition, commonly associated neuropsychological difficulties in intelligence, memory, executive functioning, attention, processing speed, language, visuospatial skills, motor skills, and affect/mood are explored.

Prolyl-4-Hydroxylase Α Subunit 2 Promotes Breast Cancer Progression And Metastasis By Regulating Collagen Deposition, Gaofeng Xiong, Lei Deng, Jieqing Zhu, Piotr G. Rychahou, Ren Xu

Markey Cancer Center Faculty Publications

BACKGROUND: Increased collagen deposition provides physical and biochemical signals to support tumor growth and invasion during breast cancer development. Therefore, inhibition of collagen synthesis and deposition has been considered a strategy to suppress breast cancer progression. Collagen prolyl-4-hydroxylase α subunit 2 (P4HA2), an enzyme hydroxylating proline residues in -X-Pro-Gly- sequences, is a potential therapeutic target for the disorders associated with increased collagen deposition. However, expression and function of P4HA2 in breast cancer progression are not well investigated.

METHODS: Gene co-expression analysis was performed in the published microarray datasets to identify potential regulators of collagen I, III, and IV in human …

Gold(Iii)-Dithiocarbamato Peptidomimetics In The Forefront Of The Targeted Anticancer Therapy: Preclinical Studies Against Human Breast Neoplasia, Chiara Nardon, Sara M. Schmitt, Huanjie Yang, Jian Zuo, Delores Fregona, Q. Ping Dou

Oncology Faculty Publications

Since the serendipitous discovery of cisplatin, platinum-based drugs have become well-established antitumor agents, despite the fact that their clinical use is limited by many severe side-effects. In order to both improve the chemotherapeutic index and broaden the therapeutic spectrum of current drugs, our most recent anti-neoplastic agents, Au(III) complexes, were designed as carrier-mediated delivery systems exploiting peptide transporters, which are up-regulated in some cancers. Among all, we focused on two compounds and tested them on human MDA-MB-231 (resistant to cisplatin) breast cancer cell cultures and xenografts, discovering the proteasome as a major target both in vitro and in vivo. …

Efficacy Of A Novel Examination Maneuver In Diagnosing Meniscal Pathology, Eric J. Freeh, Ryan Lurtsema

UNM Orthopaedic Research Journal

In this retrospective study we examine the effectiveness of the here named “Twist test” in diagnosing meniscal pathology. In preparation for this study, a literature review was conducted to look at commonly used “gold standard” exam maneuvers utilized in the diagnosis of meniscal lesions. The data from these studies was used as comparisons against the twist test. Medical records of patients who underwent knee arthroscopy from the 2013 calendar year were pulled and assessed for positive or negative Twist test results. These results were then correlated with Magnetic Resonance Imaging (MRI), and more definitively, arthroscopic findings. With this data, we …

Congenital Scoliosis: A Retrospective Chart Review, Antony Kalllur, Azadeh F. Fotouhie, Skye C. King

UNM Orthopaedic Research Journal

Background: The etiology, severity and prognosis of congenital scoliosis depend on multiple factors, with limited data in the literature. There is also limited data on surgical correction based on the underlying vertebral anomaly. Given the progressive nature of the disease and eventual need for surgical intervention, the study was designed to obtain more data, assess disease presentation and progression in relation to environmental and physical characteristics, and evaluate surgical predictors to elucidate the disease and understand its prognosis in relation to various factors.

Methods: Using a retrospective chart review, we created a database for patients with congenital scoliosis seen at …
