  • Rapid Effects of LH on Gene Expression in the Mural Granulosa Cells of Mouse Periovulatory Follicles
    REPRODUCTIONRESEARCH Rapid effects of LH on gene expression in the mural granulosa cells of mouse periovulatory follicles Martha Z Carletti and Lane K Christenson Department of Molecular and Integrative Physiology, University of Kansas Medical Center, 3075 KLSIC, 3901 Rainbow Boulevard, Kansas City, Kansas 66160, USA Correspondence should be addressed to L K Christenson; Email: [email protected] Abstract LH acts on periovulatory granulosa cells by activating the PKA pathway as well as other cell signaling cascades to increase the transcription of specific genes necessary for ovulation and luteinization. Collectively, these cell signaling responses occur rapidly (within minutes); however, presently no high throughput studies have reported changes before 4 h after the LH surge. To identify early response genes that are likely critical for initiation of ovulation and luteinization, mouse granulosa cells were collected before and 1 h after hCG. Fifty-seven gene transcripts were significantly (P!0.05) upregulated and three downregulated following hCG. Twenty-four of these transcripts were known to be expressed after the LH/hCG surge at later time points, while 36 were unknown to be expressed by periovulatory granulosa cells. Temporal expression of several transcripts, including the transcription factors Nr4a1, Nr4a2, Egr1, Egr2, Btg1, and Btg2, and the epidermal growth factor (EGF)-like ligands Areg and Ereg, were analyzed by quantitative RT-PCR, and their putative roles in granulosa cell function are discussed. Epigen (Epgn), another member of the family of EGF-like ligands was identified for the first time in granulosa cells as rapidly induced by LH/hCG. We demonstrate that Epgn initiates cumulus expansion, similar to the other EGF-receptor ligands Areg and Ereg.

Studies with indole-3-carbinol and its dimeric product, 3,3’-diindolylmethane (DIM), suggest that these compounds have the ability to deregulate multiple cellular signaling pathways that are essential for tumor growth and spread. These natural compounds are also effective modulators of transcription factors and non-coding RNAs. These effects explain their ability to inhibit tumor spread and to overcome drug resistance. In this work, pertinent literature on the effects of DIM and its synthetic derivatives on resistant tumors and resistance mechanisms in tumors is highlighted.

  • The Molecular Mechanisms by Which Vitamin D Prevents Insulin Resistance and Associated Disorders
    International Journal of Molecular Sciences Review The Molecular Mechanisms by Which Vitamin D Prevents Insulin Resistance and Associated Disorders Izabela Szymczak-Pajor 1 ,Józef Drzewoski 2 and Agnieszka Sliwi´ ´nska 1,* 1 Department of Nucleic Acid Biochemistry, Medical University of Lodz, 251 Pomorska Str., 92-213 Lodz, Poland; [email protected] 2 Central Teaching Hospital of the Medical University of Lodz, 251 Pomorska Str., 92-213 Lodz, Poland; [email protected] * Correspondence: [email protected] Received: 9 August 2020; Accepted: 9 September 2020; Published: 11 September 2020 Abstract: Numerous studies have shown that vitamin D deficiency is very common in modern societies and is perceived as an important risk factor in the development of insulin resistance and related diseases such as obesity and type 2 diabetes (T2DM). While it is generally accepted that vitamin D is a regulator of bone homeostasis, its ability to counteract insulin resistance is subject to debate. The goal of this communication is to review the molecular mechanism by which vitamin D reduces insulin resistance and related complications. The university library, PUBMED, and Google Scholar were searched to find relevant studies to be summarized in this review article. Insulin resistance is accompanied by chronic hyperglycaemia and inflammation. Recent studies have shown that vitamin D exhibits indirect antioxidative properties and participates in the maintenance of normal resting ROS level. Appealingly, vitamin D reduces inflammation and regulates Ca2+ level in many cell types. Therefore, the beneficial actions of vitamin D include diminished insulin resistance which is observed as an improvement of glucose and lipid metabolism in insulin-sensitive tissues.

  • NF-Κb Signaling in Gastric Cancer
    Review NF‐κB Signaling in Gastric Cancer Olga Sokolova and Michael Naumann * Institute of Experimental Internal Medicine, Otto von Guericke University Magdeburg, Magdeburg 39120, Germany; [email protected] * Correspondence: [email protected]; Tel.: +49‐391‐671‐3227 Abstract: Gastric cancer is a leading cause of cancer death worldwide. Diet, obesity, smoking and chronic infections, especially with Helicobacter pylori, contribute to stomach cancer development. H. pylori possesses a variety of virulence factors including encoded factors from the cytotoxin‐associated gene pathogenicity island (cagPAI) or vacuolating cytotoxin A (VacA). Most of the cagPAI‐encoded products form a type 4 secretion system (T4SS), a pilus‐like macromolecular transporter, which translocates CagA into the cytoplasm of the host cell. Only H. pylori strains carrying the cagPAI induce the transcription factor NF‐κB, but CagA and VacA are dispensable for direct NF‐κB activation. NF‐κB‐driven gene products include cytokines/chemokines, growth factors, anti‐apoptotic factors, angiogenesis regulators and metalloproteinases. Many of the genes transcribed by NF‐κB promote gastric carcinogenesis. Since it has been shown that chemotherapy‐caused cellular stress could elicit activation of the survival factor NF‐κB, which leads to acquisition of chemoresistance, the NF‐κB system is recommended for therapeutic targeting. Research is motivated for further search of predisposing conditions, diagnostic markers and efficient drugs to improve significantly the overall survival of patients. In this review, we provide an overview about mechanisms and consequences of NF‐κB activation in gastric mucosa in order to understand the role of NF‐κB in gastric carcinogenesis. Keywords: NF‐κB; inflammation; gastric cancer; Helicobacter pylori; VacA toxin; Type 4 secretion system; tumor microenvironment; chemoresistance 1.

  • NR4A2 Is Regulated by Gastrin and Influences Cellular Responses of Gastric Adenocarcinoma Cells
    NR4A2 Is Regulated by Gastrin and Influences Cellular Responses of Gastric Adenocarcinoma Cells Kristine Misund1, Linn-Karina Myrland Selvik1,2, Shalini Rao1,2, Kristin Nørsett1, Ingunn Bakke1, Arne K. Sandvik1,3, Astrid Lægreid1, Torunn Bruland1, Wenche S. Prestvik2, Liv Thommesen1,2* 1 Department of Cancer Research and Molecular Medicine, Norwegian University of Science and Technology (NTNU), Trondheim, Norway, 2 Faculty of Technology, Sør-Trøndelag University College, Trondheim, Norway, 3 Department of Gastroenterology and Hepatology, Medical Clinic, St. Olav’s University Hospital, Trondheim, Norway Abstract The peptide hormone gastrin is known to play a role in differentiation, growth and apoptosis of cells in the gastric mucosa. In this study we demonstrate that gastrin induces Nuclear Receptor 4A2 (NR4A2) expression in the adenocarcinoma cell lines AR42J and AGS-GR, which both possess the gastrin/CCK2 receptor. In vivo, NR4A2 is strongly expressed in the gastrin responsive neuroendocrine ECL cells in normal mucosa, whereas gastric adenocarcinoma tissue reveals a more diffuse and variable expression in tumor cells. We show that NR4A2 is a primary early transient gastrin induced gene in adenocarcinoma cell lines, and that NR4A2 expression is negatively regulated by inducible cAMP early repressor (ICER) and zinc finger protein 36, C3H1 type-like 1 (Zfp36l1), suggesting that these gastrin regulated proteins exert a negative feedback control of NR4A2 activated responses. FRAP analyses indicate that gastrin also modifies the nucleus-cytosol shuttling of NR4A2, with more NR4A2 localized to cytoplasm upon gastrin treatment. Knock-down experiments with siRNA targeting NR4A2 increase migration of gastrin treated adenocarcinoma AGS-GR cells, while ectopically expressed NR4A2 increases apoptosis and hampers gastrin induced invasion, indicating a tumor suppressor function of NR4A2.

    2004 Eastern Society for Pediatric Research 16th Annual Meeting Program Guide March 26–28, 2004 Hyatt Regency Old Greenwich, CT In cooperation with the New York Academy of Medicine New for 2004 We are pleased to announce that we have engaged the services of the New York Academy of Medicine (NYAM) to run our 2004 meeting. They will also sponsor the CME program. While our recent meetings have been terrific, the administrative burden has exceeded what could reasonably be expected of our volunteers. We expect the engagement of the professional meeting planners at the NYAM will further enhance our meeting. This will include improved informatics enabling presenters to load their PowerPoint presentations at a central station in advance, avoiding some of the glitches we encountered last year.

Previous studies have highlighted its association with clinicopathological parameters, tumorigenesis and therapeutic resistance in cancers. In addition, recent studies unraveled its contribution to the suppression of antitumor immunity, suggesting that inhibition of Nurr1 is a potential method to repress cancer aggressiveness and disrupt tumor immune tolerance. In line with this evidence, the present review provides the roles of Nurr1 in tumor progression and the associated underlying molecular mechanisms. Moreover, the significance of Nurr1 in promoting immune tolerance and potential strategies for Nurr1 inhibition are highlighted. Abstract: Nuclear receptor related-1 protein (Nurr1), coded by an early response gene, is involved in multiple cellular and physiological functions, including proliferation, survival, and self-renewal. Dysregulation of Nurr1 has been frequently observed in many cancers and is attributed to multiple transcriptional and post-transcriptional mechanisms.
