INTRODUCTION. Chromosome instability (CIN) is one of the hallmarks of cancer cells 1 and is often mutually exclusive from hypermutation genotypes. Hypermutations in cancer cells are due to defects in DNA mismatch repair genes, including MLH1 and MSH2; 2 however, the cause of CIN is still elusive.

Most solid tumor cells with CIN are aneuploidy, indicating that Cited by:   DNA Topoisomerases and Cancer by Yves Pommier,available at Book Depository with free delivery : Yves Pommier.

Beginning with the Escherichia coli co protein, or bacterial DNA topoisomerase I, an ever-increasing number of enzymes has been identified that catalyze changes in the linkage of DNA strands. DNA topoisomerases are ubiquitous in nature and have been shown to play critical roles in most p- cesses involving DNA, including DNA replication, transcription, and rec- bination.

One category of topoisomerase II inhibitors acts by stabilizing the covalently bound form of topoisomerase II with DNA, resulting in increased topoisomerase II-cross-linked DNA strand Size: 61KB. The DNA Topoisomerases in Biology and Medicine Gordon Research Conference and Associated Gordon Research Seminar will be a forum for the presentation and discussion of cutting-edge scientific advances in the study of DNA and RNA topoisomerases and their interacting partners, and their relevance in the origin and treatment of human diseases.

DNA Repair and Cancer Therapy: Molecular Targets and Clinical Applications, Second Edition provides a comprehensive and timely reference that focuses on the translational and clinical use of DNA repair as a target area for the development of diagnostic biomarkers and the enhancement of cancer treatment.

Experts on DNA repair proteins from all areas of cancer. Topoisomerases are ubiquitously expressed enzymes that overcome topological problems in genomic DNA, which can result from DNA replication, transcription and repair.

Common problems such as overwinding (positive supercoiling), knots and tangles are resolved by topoisomerases by catalyzing the breaking of one or two strands of DNA. DNA topoisomerases are marvelous molecular machines that manage the topo-logical state of the DNA in the cell.

These enzymes accomplish this feat by either passing one strand of the DNA through a break in the opposing strand (type IFile Size: 1MB. Topoisomerase inhibitors are chemical compounds that block the action of topoisomerases (topoisomerase I and II), which are enzymes that control the changes in DNA structure by catalyzing the breaking and rejoining of the phosphodiester backbone of DNA strands during the normal cell cycle.

In recent years, topoisomerases have become popular targets for cancer. DNA topoisomerases are enzymes that regulate DNA supercoiling by catalyzing the winding and unwinding of DNA strands.

They cleave the long DNA backbone, so the molecular strands can pass through one another. Scientists divide DNA topoisomerases into two groups based on the number of strands that they break.

Most chemotherapy regimens contain at least one DNA-damaging agent that preferentially affects the growth of cancer cells. This strategy takes advantage of the differences in cell proliferation between normal and cancer cells.

Chemotherapeutic drugs are usually designed to target rapid-dividing cells because sustained proliferation is a common feature of cancer [1,2].Cited by: Dna Topoisomerases In Cancer Therapy Present And Future Epub Format - Sidney Sheldon Publishing Get This From A Library Dna Topoisomerases In Cancer Therapy Present And Future Toshiwo Andoh In The Mid 80s Type I And Ii Enzymes Were Found To Be The Intracellular Targets Of.

The DNA topoisomerases are a family of important enzymes involved in different stages of the cell cycle.

DNA topoisomerases are enzymes that catalyze changes in the torsional and flexural strain of DNA molecules. Earlier studies implicated these enzymes in a variety of processes in both prokaryotes and eukaryotes, including DNA replication, transcription, recombination, and chromosome : Mary-Ann Bjornsti, Scott H.

Kaufmann. The various problems of disentangling DNA strands or duplexes in a cell are all rooted in the double-helical structure of DNA. Three distinct subfamilies of enzymes, known as the DNA topoisomerases, have evolved to solve these problems.

This review focuses on work in the past decade on the mechanisms and cellular functions of these enzymes. Newly discovered. interactions of topoisomerases with DNA repair ma­ chinery, besides the induction of cell cycle perturba­ tions and apoptosis will greatly facilitate the optimal use of topoisomerases as anticancer drugs.

Most of the topoisomerase inhibitors approved by the U.S. Food and Drug Administration are utilized to treat colon, lung, and ovarian cancer, as well as pediatric tumors.

Checkpoint Responses in Cancer Therapy summarizes the advances made over the past 20 years, identifying components of cell-cycle checkpoints and their molecular regulation during checkpoint activation and validating the use of checkpoint proteins as targets for the development of anticancer drugs.

Mammals have two type II DNA topoisomerases, TOP2A and TOP2B. Bacteria have two type II DNA topoisomerases, DNA gyrase and DNA topoisomerase IV. DNA topoisomerases are targets for both anti-bacterial agents and anti-cancer agents. Mechanistic understanding of these enzymes has been advanced by solving crystal structures for domains of the enzymes.Our Cell Cycle & DNA Damage Repair poster summarizes the stages of the cell cycle and DNA repair.
