Lurie Cancer Center of Northwestern University, Chicago, USA Preclinical models for the identi®cation of prostate cancer chemoprevention agents are lacking. Based upon the notion that clinically useful chemoprevention agents should exhibit selective activity against early stage disease, studies were undertaken to assess whether chemoprevention agents selectively inhibited the growth of early stage prostate cancer, as compared to late stage cancer. First, a series of cell and molecular studies were performed, which, when taken together, validated the use of a panel of prostate cell lines as a model of the different stages of carcinogenesis. Next, therapeutic responsiveness to ten different cytotoxic or chemoprevention agents was evaluated. Chemoprevention agents exhibited selective activity against normal and early transformed prostate tissue, whereas cytotoxic agents were non-speci®c. Selective activity against early versus advanced prostate cancer cells is identi®ed as a potential screening method for chemoprevention agents.

  • UNIT-I DNA: Definition, Structure & Discovery DNA
    SRINIVASAN ARTS AND SCIENCE COLLEGE (CO-ED) PERAMBALUlR - 621212 DEPARTMENT OF BIOTECHNOLOGY CLASS : I M.SC., BIOTECHNOLOGY SUBJECT: rDNA TECHNOLOGY SUB CODE : P16BT21 UNIT-I DNA: Definition, Structure & Discovery DNA The structure of the DNA double helix. The atoms in the structure are colour-coded by element and the detailed structures of two base pairs are shown in the bottom right. The structure of part of a DNA double helix Deoxyribonucleic acid is a molecule composed of two polynucleotide chains that coil around each other to form a double helix carrying genetic instructions for the development, functioning, growth and reproduction of all known organisms and many viruses. DNA and ribonucleic acid (RNA) are nucleic acids. Alongside proteins, lipids and complex carbohydrates (polysaccharides), nucleic acids are one of the four major types of macromolecules that are essential for all known forms of life. The two DNA strands are known as polynucleotides as they are composed of simpler monomeric units called nucleotides. Each nucleotide is composed of one of four nitrogen-containing nucleobases (cytosine [C], guanine [G], adenine [A] or thymine [T]), a sugar called deoxyribose, and a phosphate group. The nucleotides are joined to one another in a chain by covalent bonds (known as the phospho-diester linkage) between the sugar of one nucleotide and the phosphate of the next, resulting in an alternating sugar-phosphate backbone. The nitrogenous bases of the two separate polynucleotide strands are bound together, according to base pairing rules (A with T and C with G), with hydrogen bonds to make double- stranded DNA. The complementary nitrogenous bases are divided into two groups, pyrimidines and purines.

  • Copy of Growing Into Their
    Growing into their Own? Plant Molecular Farming and the Pursuit of Biotechnological Sovereignty for Lower and Middle Income Countries. Ana Christine Zeghibe Submitted in Partial Fulfillment of the Prerequisite for Honors In Biological Sciences Under the advisement of Martina Koniger, Ph.D. Wellesley College May 2021 © 2021 Ana Zeghibe Acknowledgements I am extraordinarily grateful for the support, kindness and guidance of my major and thesis advisor Professor Martina Koniger. The strong plant biology influence on an otherwise biotechnologically and medically oriented thesis was largely inspired by her own expertise in chloroplasts. When coming to this thesis, I knew I wanted to write something that was not simply a research paper, but a synthesis of ideas and observations about science and its interactions with the world beyond the laboratory that I had made over my 4 years at Wellesley. Thank you, as always, for allowing me to develop this unusual project, for keeping me sane through the many pitfalls and trials of writing, and for making me fall in love with science communication and plant biology. Thank you to my committee member Professor Natali Valdez for supporting and guiding my analyses and thoughts on the societal implications of plant molecular pharming. Professor Valdez's classes and work in Feminist Science and Technology Studies strongly influenced the later chapters of this thesis, helping me to think about the hopeful possibilities and critical realities for humanitarian applications of this unusual biotechnology. I am extremely thankful for her critiques of my argument and writing, her insight into the existing literature on biotechnological sovereignty and her passion for this project's potential.

  • Problem of Genetically Modified Foods Safety: a Toxicologist’S View
    REVIEWS UDC 604.6 doi: 10.15407/biotech9.01.007 PROBLEM OF GENETICALLY MODIFIED FOODS SAFETY: A TOXICOLOGIST’S VIEW E. L. LEVITSKY Palladin Institute of Biochemistry of the National Academy of Sciences of Ukraine, Kiyv E-mail: [email protected] Received 20.10.2015 This study aimed to analyze the published literature regarding the problem of safety of consuming food products containing genetically modified organisms. Genetically modified food products are given a brief definition, purpose and methods of their production are described, and the pro- and contra- arguments for their consumption are presented. The discussion is mostly focused on results of evaluating possible toxicity of such foods and their safety for macroorganism using traditional methods of toxicological analysis. Test results for long-term toxic effects, namely allergenicity, carcinogenicity, reproductive toxicity, and the possibility of mutagenic effects of these food products on the human body and the intestinal microflora are discussed separately. These data are based on the current understanding of the laws of the penetration and functioning of foreign genetic material outside the body, its entry and the possibility of integration into the genome during intake of foods manufactured by genetic engineering. The basic principles of the toxicological and hygienic regulation of these food products are also considered. An analysis of published experimental results allowed to draw a general conclusion about the absence of reliable scientific information indicating the presence of the toxic properties of genetically modified foods, and therefore of credible evidence of the dangers of consuming for humans and pets. Key words: genetically modified foods, toxicity, safety.

  • Review on the Role of the Human Polyomavirus JC in the Development of Tumors Serena Delbue1* , Manola Comar2,3 and Pasquale Ferrante1,4
    Delbue et al. Infectious Agents and Cancer (2017) 12:10 DOI 10.1186/s13027-017-0122-0 REVIEW Open Access Review on the role of the human Polyomavirus JC in the development of tumors Serena Delbue1* , Manola Comar2,3 and Pasquale Ferrante1,4 Abstract Almost one fifth of human cancers worldwide are associated with infectious agents, either bacteria or viruses, and this makes the possible association between infections and tumors a relevant research issue. We focused our attention on the human Polyomavirus JC (JCPyV), that is a small, naked DNA virus, belonging to the Polyomaviridae family. It is the recognized etiological agent of the Progressive Multifocal Leukoencephalopathy (PML), a fatal demyelinating disease, occurring in immunosuppressed individuals. JCPyV is able to induce cell transformation in vitro when infecting non-permissive cells, that do not support viral replication and JCPyV inoculation into small animal models and non human primates drives to tumor formation. The molecular mechanisms involved in JCPyV oncogenesis have been extensively studied: the main oncogenic viral protein is the large tumor antigen (T-Ag), that is able to bind, among other cellular factors, both Retinoblastoma protein (pRb) and p53 and to dysregulate the cell cycle, but also the early proteins small tumor antigen (t-Ag) and Agnoprotein appear to cooperate in the process of cell transformation. Consequently, it is not surprising that JCPyV genomic sequences and protein expression have been detected in Central Nervous System (CNS) tumors and colon cancer and an association between this virus and several brain and non CNS-tumors has been proposed. However, the significances of these findings are under debate because there is still insufficient evidence of a casual association between JCPyV and solid cancer development.
