Computational Modeling of PI3K/AKT and MAPK Signaling Pathways in Melanoma Cancer
(2016-03)Background Malignant melanoma is an aggressive tumor of the skin and seems to be resistant to current therapeutic approaches. Melanocytic transformation is thought to occur by sequential accumulation of genetic and ... -
Cooperative Effects of Akt-1 and Raf-1 on the Induction of Cellular Senescence in Doxorubicin or Tamoxifen Treated Breast Cancer Cells
(2011-08)Escape from cellular senescence induction is a potent mechanism for chemoresistance. Cellular senescence can be induced in breast cancer cell lines by the removal of estrogen signaling with tamoxifen or by the accumulation ... -
Crc Is Involved in Catabolite Repression Control of the bkd Operons of Pseudomonas putida and Pseudomonas aeruginosa
(East Carolina University, 2000-02)Crc (catabolite repression control) protein of Pseudomonas aeruginosa has shown to be involved in carbon regulation of several pathways. In this study, the role of Crc in catabolite repression control has been studied in ... -
The cyclic-di-GMP signaling pathway in the Lyme disease spirochete,
(2014-05)In nature, the Lyme disease spirochete Borrelia burgdorferi cycles between the unrelated environments of the Ixodes tick vector and mammalian host. In order to survive transmission between hosts, B. burgdorferi must be ... -
CYTOKINE-BASED FUSION PROTEINS FOR TREATMENT OF MULTIPLE SCLEROSIS
(2014-12-30)The present invention provides fusion proteins including an autoimmune antigen, an allergen antigen or an alloantigen, and an anti-inflammatory cytokine. Compositions and meth ods including the fusion proteins are also provided. -
Cytokine-Neuroantigen Fusion Proteins as a New Class of Tolerogenic, Therapeutic Vaccines for Treatment of Inflammatory Demyelinating Disease in Rodent Models of Multiple Sclerosis
(2012-08)Myelin-specific induction of tolerance represents a promising means to modify the course of autoimmune inflammatory demyelinating diseases such as multiple sclerosis (MS). Our laboratory has focused on a novel preclinical ... -
Cytokines and neuroantigens for treatment of immune disorders
(2017-05-10)The present invention provides methods of regulating an immunological disorder comprising administering to a subject an effective amount of (i) an autoimmune antigen in conjunction with (ii) an anti-inflammatory cytokine. ... -
Cytotoxic activity of the novel small molecule AKT inhibitor SC66 in hepatocellular carcinoma cells
(2015-01)Hepatocellular carcinoma (HCC) is characterized by limited response to current drug therapies. Here, we report that SC66, a novel AKT inhibitor, reduced cell viability in a dose- and time-dependent manner, inhibited colony ... -
Deficiency of a Sinorhizobium meliloti bacA Mutant in Alfalfa Symbiosis Correlates with Alteration of the Cell Envelope
(East Carolina University, 2002-10)The BacA protein is essential for the long-term survival of Sinorhizobium meliloti and Brucella abortus within acidic compartments in plant and animal cells, respectively. Since both the S. meliloti and B. abortus bacA ... -
DELINEATING THE MECHANISM OF AGGREGATE OR BIOFILM FORMATION IN THE LYME DISEASE SPIROCHETE BORRELIA BURGDORFERI
(East Carolina University, 2021-07-14)Borrelia burgdorferi, the spirochete causing Lyme disease, is transmitted to a vertebrate host by the bite of an infected Ixodes scapularis tick. The spirochete develops antibiotic resistance in humans likely due to the ... -
DELINEATING THE ROLE OF SOLUBLE CD25 AS AN IMMUNOREGULATORY MOLECULE THAT PROMOTES A LOW-ZONE IL-2 SIGNALING ENVIRONMENT FAVORABLE FOR THE SELECTION OF CD25HIGH FOXP3HIGH T CELLS
(East Carolina University, 2021-07-22)Autoimmune diseases develop due to the breakdown of tolerogenic mechanisms that normally maintain immune homeostasis. CD4+ CD25+ FOXP3+ regulatory T cells (Tregs) are critical in the maintenance of tolerance and the ... -
Development of small-molecule inhibitors of the initiating proteases, C1r and C1s, of the classical complement pathway
(East Carolina University, 2019-12-12)Complement is a proteolytic cascade that upon activation plays a key effector role in the innate immune system and acts to prime the adaptive immune response. During normal homeostatic events, complement is tightly regulated ... -
Differential regulation of the attachment of KSHV infected human B cells to ECM by KSHV encoded gB and cellular alpha-V integrins
(East Carolina University, 2008-07)Kaposi’s sarcoma-associated herpesvirus (KSHV) has two modes replication: latent and lytic replication. Reactivation from latency is dictated, in part, by the cell cycle. Herein, we have attempted to delineate the importance ... -
Direct Inhibition of RNAse T2 Expression by the HTLV-1 Viral Protein Tax
(2011-08)Adult T-cell leukemia (ATL) is one of the primary diseases caused by Human T-cell Leukemia Virus type 1 (HTLV-1) infection. The virally-encoded Tax protein is believed to initiate early events in the development of this ...
