The Rice Pentatricopeptide Repeat Protein Ppr756 Is Involved In Pollen Development By Affecting Multiple Rna Editing In Mitochondria., Qiannan Zhang, Yanghong Xu, Jishuai Huang, Kai Zhang, Haijun Xiao, Xiaojian Qin, Linlin Zhu, Yingguo Zhu, Jun Hu

Department of Medicine Faculty Papers

In land plants, the pentatricopeptide repeat (PPR) proteins form a large family involved in post-transcriptional processing of RNA in mitochondria and chloroplasts, which is critical for plant development and evolutionary adaption. Although studies showed a number of PPR proteins generally influence the editing of organellar genes, few of them were characterized in detail in rice. Here, we report a PLS-E subclass PPR protein in rice, PPR756, loss of function of which led to the abolishment of RNA editing events among three mitochondrial genes including

Systemic Proteome Alterations Linked To Early Stage Pancreatic Cancer In Diabetic Patients, Hong Peng, Sheng Pan, Yuanqing Yan, Randall E Brand, Gloria M Petersen, Suresh T Chari, Lisa A Lai, Jimmy K Eng, Teresa A Brentnall, Ru Chen

Faculty, Staff and Students Publications

BACKGROUND: Diabetes is a risk factor associated with pancreatic ductal adenocarcinoma (PDAC), and new adult-onset diabetes can be an early sign of pancreatic malignancy. Development of blood-based biomarkers to identify diabetic patients who warrant imaging tests for cancer detection may represent a realistic approach to facilitate earlier diagnosis of PDAC in a risk population.

METHODS: A spectral library-based proteomic platform was applied to interrogate biomarker candidates in plasma samples from clinically well-defined diabetic cohorts with and without PDAC. Random forest algorithm was used for prediction model building and receiver operating characteristic (ROC) curve analysis was applied to evaluate the prediction …

Circulating Tumor Cell And Regulator T-Lymphocyte In Core Biopsy For Breast Cancer, Sonar Soni Panigoro, Diani Kartini, Dewi Wulandari, Arif Supono

The New Ropanasuri Journal of Surgery

Introduction: Breast cancer is the most common malignancy found in Indonesia. Core biopsy is one of the modalities used in breast cancer diagnosis with sensitivity of 91-99% and specificity of 96-100%. The procedure causes damage to tumor tissue thus causing tumor cells to enter circulation (CTC) and therefore acute inflammation and infiltration of inflammatory cells. In the final phase of infiltration, the number of Tregs cells will increase, as well as secretion of TGFβ and IL-10, creation of immunosuppresion microenvironment, COX2 stimulation by TGFβ then conversion of CD4+ T cells into FoxP3+ (Tregs), therefore the number of Tregs cells will …

Innervation: The Missing Link For Biofabricated Tissues And Organs, Suradip Das, Wisberty J. Gordián-Vélez, Harry C. Ledebur, Foteini Mourkiot, Panteleimon Rompolas, H. . Isaac Chen, Mijail D. Serruya, D. Kacy Cullen

Department of Neurology Faculty Papers

Innervation plays a pivotal role as a driver of tissue and organ development as well as a means for their functional control and modulation. Therefore, innervation should be carefully considered throughout the process of biofabrication of engineered tissues and organs. Unfortunately, innervation has generally been overlooked in most non-neural tissue engineering applications, in part due to the intrinsic complexity of building organs containing heterogeneous native cell types and structures. To achieve proper innervation of engineered tissues and organs, specific host axon populations typically need to be precisely driven to appropriate location(s) within the construct, often over long distances. As such, …

Alteration Of Iron Responsive Gene Expression In Arabidopsis Glutaredoxin S17 Loss Of Function Plants With Or Without Iron Stress, Ninghui Cheng, Han Yu, Xiaolan Rao, Sunghun Park, Erin L Connolly, Kendal D Hirschi, Paul A Nakata

Children’s Nutrition Research Center Staff Publications

Iron (Fe) is a mineral nutrient and a metal cofactor essential for plants. Iron limitation can have detrimental effects on plant growth and development, while excess iron inside plant cells leads to oxidative damage. As a result, plants have evolved complex regulatory networks to respond to fluctuations in cellular iron concentrations. The mechanisms that regulate these responses however, are not fully understood. Heterologous expression of an Arabidopsis thaliana monothiol glutaredoxin S17 (GRXS17) suppresses the over-accumulation of iron in the Saccharomyces cerevisiae Grx3/Grx4 mutant and disruption of GRXS17 causes plant sensitivity to exogenous oxidants and iron deficiency stress. GRXS17 may act …

Comparative Molecular Transporter Properties Of Cyclic Peptides Containing Tryptophan And Arginine Residues Formed Through Disulfide Cyclization, Eman H. M. Mohammed, Dindyal Mandal, Saghar Mozaffari, Magdy Abdel-Hamied Zahran, Amany Mostafa Osman, Rakesh Kumar Tiwari, Keykavous Parang

Pharmacy Faculty Articles and Research

We have previously reported cyclic cell-penetrating peptides [WR]₅ and [WR]₄ as molecular transporters. To optimize further the utility of our developed peptides for targeted therapy in cancer cells using the redox condition, we designed a new generation of peptides and evaluated their cytotoxicity as well as uptake behavior against different cancer cell lines. Thus, cyclic [C(WR)_xC] and linear counterparts (C(WR)_xC), where x = 4–5, were synthesized using Fmoc/tBu solid-phase peptide synthesis, purified, and characterized. The compounds did not show any significant cytotoxicity (at 25 µM) against ovarian (SK-OV-3), leukemia (CCRF-CEM), gastric adenocarcinoma (CRL-1739), breast …

Myeloid-Derived Suppressor Cells Infiltration In Non-Small-Cell Lung Cancer Tumor And Mage-A4 And Ny-Eso-1 Expression, Zhenbo Hou, Xiao Liang, Xinmei Wang, Ziqiang Zhou, Guilan Shi

Bioelectrics Publications

Cancer/testis antigens melanoma‑associated antigen 4 (MAGE‑A4) and New York esophageal squamous cell carcinoma‑1 (NY‑ESO‑1) are of clinical interest as biomarkers and present valuable targets for immunotherapy; however, they are poor prognostic markers in non‑small cell lung cancer (NSCLC). In addition, myeloid derived suppressor cells (MDSCs) are recognized as a key element in tumor escape and progression. The aim of the present study was to investigate the diagnostic and prognostic value of MAGE‑A4 and NY‑ESO‑1, and their association with MDSCs in NSCLC samples. The expression levels of MAGE‑A4 and NY‑ESO‑1, and the infiltration of MDSCs (CD33+), were analyzed by immunohistochemistry of …

Scope Of Attention Variation As A Function Of Anxiety And Depression, Kathleen Anne O'Donnell

Electronic Theses, Projects, and Dissertations

As a social species, correct emotional perception is so vital, that the human brain has evolved a mechanism to control attentional choices by exerting a narrowed field of perception during danger, called the scope of attention (SoA). The SoA determines what information will be focused on or ignored by blocking the perception of non-relevant items and increasing selective focus on danger; even if danger is merely a sad-face. The emotional items blocked from perception cannot be remembered because they were never perceived. But, attention-control to emotional stimuli also varies with mood, as seen in mood-disorders. A mood-disorder’s effect upon the …

PURPOSE: Brain metastases are a common sequelae of breast cancer. Survival varies widely based on diagnosis-specific prognostic factors (PF). We previously published a prognostic index (Graded Prognostic Assessment [GPA]) for patients with breast cancer with brain metastases (BCBM), based on cohort A (1985-2007, n = 642), then updated it, reporting the effect of tumor subtype in cohort B (1993-2010, n = 400). The purpose of this study is to update the Breast GPA with a larger contemporary cohort (C) and compare treatment and survival across the 3 cohorts.

Hypoxia-Inducible Factor (Hif)-2Α Reprograms Liver Macrophages To Protect Against Acute Liver Injury Via The Production Of Interleukin-6, Rachel Y Gao, Meng Wang, Qihui Liu, Dechun Feng, Yankai Wen, Yang Xia, Sean P Colgan, Holger K Eltzschig, Cynthia Ju

Faculty, Staff and Student Publications

BACKGROUND AND AIMS: Acetaminophen (APAP) overdose represents the most frequent cause of acute liver failure, resulting in death or liver transplantation in more than one third of patients in the United States. The effectiveness of the only antidote, N-acetylcysteine, declines rapidly after APAP ingestion, long before patients are admitted to the clinic with symptoms of severe liver injury. The direct hepatotoxicity of APAP triggers a cascade of innate immune responses that may exacerbate or limit the progression of tissue damage. A better understanding of this complex mechanism will help uncover targets for therapeutic interventions.

APPROACH AND RESULTS: We observed that …

Role Of Micro-Rna For Pain After Surgery: Narrative Review Of Animal And Human Studies, Juan P Cata, Aysegul Gorur, Xiaoyi Yuan, Nathaniel K Berg, Anil K Sood, Holger K Eltzschig

Faculty, Staff and Student Publications

One of the most prevalent symptoms after major surgery is pain. When postoperative pain treatment is unsatisfactory, it can lead to poor surgical recovery, decreased quality of life, and increased health care costs. Current analgesics, single or in combination, have limited efficacy due to low potency, limited duration of action, toxicities, and risk of addiction. The lack of nonaddictive strong analgesics along with the over prescription of opioids has led to an opioid epidemic in the United States. Therefore, there is an urgent need for the development of newer analgesics. Microribonucleic acids (miRNAs) are small noncoding RNA molecules that modulate …
