Abstract

Ribosome-inactivating proteins (RIPs) are rRNA N-glycosylases isolated mainly from plants that catalyze the hydrolysis of the N-glycosidic bond of a specific adenosine in the sarcin-ricin loop (SRL) of the major ribosomal RNA. Because the SRL is crucial for anchoring translation elongation factors, RIPs cause inactivation of ribosomes. They have been classified into two types based on the presence (type 2 RIPs) or absence (type 1 RIPs) of a lectin chain that can turn type 2 RIPs into potent toxins, such as ricin or abrin. The biological role of these proteins is unknown, but they are thought to be a defense mechanism of some plants against pathogens and predators. Because of their enzymatic action, RIPs show several biological activities, among which antiviral, antifungal and antiproliferative activities stand out. The most promising application of RIPs is their use as a component of immunotoxins, in which RIPs are linked to antibodies that mediate their binding and internalization by malignant cells. In agriculture, RIPs have been shown to increase resistance against viruses, fungi and insects in transgenic plants. The studies collected in this book provide the reader with an overview of the most current and interesting lines of research in the field of RIPs and their applications in medicine and agriculture. Thus, the reprint includes the isolation and biological properties of some new RIPs, both type 1 and type 2, the mechanisms of toxicity of previously described RIPs and two extensive reviews, one on the antiviral activity of RIPs and the other on the strategies used to improve their pharmacological properties.

Abstract

This thesis describes research into the mode of function, inhibition, and evolution of the ribosomal catalytic center, the Peptidyl Transferase Center (PTC)--research that has already led to attempts at improving PTC antibiotics. The PhD candidate carried out two parallel studies. One using a combination of X-ray crystallography, biochemistry, molecular biology, and theoretical studies to obtain crystal structures of ribosomal particles with antibiotics that target the PTC, revealing the modes of action, resistance, cross-resistance and discrimination between ribosomes of eubacterial pathogens and eukaryotic hosts. In the second parallel study, the candidate synthesized a ribosomal substructure--one that may represent the minimal entity capable of catalyzing peptide bond formation--shedding light on the origin of the ribosome itself.

Abstract

Sex steroids, including androgens, estrogens, and progestogens, are knownto have widespread physiological actions beyond the reproductive systemvia binding to the sex hormone receptors. Meanwhile, emerging evidence hasindicated that sex hormone receptor signals are involved in the outgrowth ofsome malignancies, such as prostate and breast carcinomas, as well as othersthat have not traditionally been considered as endocrine-related neoplasms. ThisSpecial Issue “Sex Hormone Receptor Signals in Human Malignancies” coversvarious aspects of the potential role of sex hormone receptors and related signalsin prostate cancer, breast cancer, and other neoplastic conditions by depictingpromising findings derived from in vitro and in vivo experiments as well as theanalyses of surgical specimens. The current observations described may thusprovide a unique insight into novel or known functions of sex hormone receptorsand related molecules.

Abstract

The ribosome is a macromolecular machine that synthesizes proteins with a high degree of speed and accuracy. Our present understanding of its structure, function and dynamics is the result of six decades of research. This book collects over 40 articles based on the talks presented at the 2010 Ribosome Meeting, held in Orvieto, Italy, covering all facets of the structure and function of the ribosome. New high-resolution crystal structures of functional ribosome complexes and cryo-EM structures of translating ribosomes are presented, while partial reactions of translation are examined in structural and mechanistic detail, featuring translocation as a most dynamic process. Mechanisms of initiation, both in bacterial and eukaryotic systems, translation termination, and novel details of the functions of the respective factors are described. Structure and interactions of the nascent peptide within, and emerging from, the ribosomal peptide exit tunnel are addressed in several articles. Structural and single-molecule studies reveal a picture of the ribosome exhibiting the energy landscape of a processive Brownian machine. The collection provides up-to-date reviews which will serve as a source of essential information for years to come.
