Abstract:

One of the major limitations on research into the control of eukaryotic DNA replication has been the lack of any cell-free system that initiates DNA replication in vitro. The first part of the disseration describes the establishment of a eukaryotic system, derived from the activated eggs of the South African clawed toad, Xenopus laevis, that efficiently initiates and completes DNA replication in vitro. Using a variety of biochemical techniques I show that DNA added to the extract in the form of sperm nuclei is efficiently replicated over a period of 4 - 6 hours. Replication of nuclear DNA repr

Abstract:

Magister Scientiae (Medical Bioscience) - MSc(MBS)<br>Introduction: Mondia whitei commonly known as "White Ginger" is a highly acclaimed medicinal plant that is extensively used across Africa. M. whitei is used as treatment for sexual dysfunction and is considered to be an aphrodisiac by traditional medicine practitioners. Yet, scientific evidence to support these claims are minimal and those that are published possess ambiguity. To date, only one study reporting the in vitro effect of the aqueous rhizome extract of M. whitei on human sperm motility is available. Therefore, the aim of the stud

Full text

Abstract:

The E3 ubiquitin ligase \(CRL4^{Cdt2}\) targets proteins for destruction during DNA replication and following DNA damage (Havens and Walter, 2011). Its substrates contain "PIP degrons" that mediate substrate binding to the processivity factor PCNA at replication forks and damage sites. The resulting PCNA-PIP degron complex forms a docking site for \(CRL4^{Cdt2}\), which ubiquitylates the substrate on chromatin. Several \(CRL4^{Cdt2}\) substrates are known, including Cdt1, multiple CDK inhibitors, Drosophila E2f1, human Set8, S. pombe Spd1, and C. elegans \(Pol\eta\) (Havens and Walter, 2011).

Bioassay-guided fractionation of the ethyl acetate extract of Virola sp.

The bioassay of three mutant yeast strains (1138, 1104, and 1353) directed the isolation of DNA-damaging alkaloids from Solanum hostmannii. These alkaloids were identified as verazine and (20R) epimer verazine. In addition, three oxoaporphine alkaloids were isolated from the bark of Papualthia sp. (Annonaceae).

Abstract:

When unreplicated or damaged DNA is present, cell cycle checkpoint pathways cause cell cycle arrest by inhibiting cyclin-dependent kinases (Cdks). In Xenopus laevis, early embryonic development consists of twelve rapid cleavage cycles between DNA replication (S) and mitosis (M) without checkpoints or gap phases. However, checkpoints are engaged in Xenopus once the embryo reaches the midblastula transition (MBT). At this point, the embryo initiates transcription, acquires gap phases between S and M phases, and establishes a functional apoptotic program. During the cell cycle, there are two mai

Abstract:

Isolation of DNA from skeletonised human remains can be problematic. In addition to DNA degradation, enhanced by high temperature and humidity, there are often potent polymerase chain reaction (PCR) inhibitors present within the samples. It is therefore important to extract the maximum amount of available DNA whilst removing any amplification inhibitors that may be present. Whilst real-time PCR methods are available for quantification and detection of PCR inhibitors the information received is limited as real-time PCR targets amplicons that are much smaller than those typically targeted in for

Abstract:

The cell cycle of eukaryotes consists of alternation between growth and DNA replication (interphase), and DNA distribution and cell-division (mitosis or M-phase). This process is regulated by a complex network of biochemical reactions. A core part of this network, called the "Cell Cycle engine" is evolutionarily conserved. The dimer of CDK1 (a protein kinase) and Cyclin proteins (the regulatory components), called M-phase Promoting Factor (MPF), and its key regulatory proteins Cdc25 and Wee1, are central parts of this cell cycle engine.

Abstract:

This master's thesis deals with the creation of a tool for the extraction of methylation level from transposon sequences. Transposons are DNA elements with ability to move or copy themselves and their activity is regulated by DNA methylation. Sequence methylation information is stored in the bisulfite data and their processing is done with parts of two existing tools in a combination with implemented modules. Created tool takes into consideration unique challenges brought in the methylation calling process by transposable elements and it's functionality is presented on a set of experiments wit

La Na+,K+-ATPase, ou pompe à sodium, est une enzyme membranaire ubiquitaire permettant le maintien des gradients sodique et potassique indispensables à la survie cellulaire. La première partie de ces travaux a été consacrée à l'étude de l'implication de cette pompe en tant que marqueur de la physiopathologie. Dans ce but, un modèle de section médullaire totale suivie d'une injection de GPL-DHA (glycerophospholipids enriched in docosahexaenoic acid) a été mis en place chez le rat.

La marmotte alpine (marmota marmota, sciuride), espece hautement sociale au systeme d'appariement decrit comme etant monogame, suscite un grand interet comme modele d'etude de la socialite chez les mammiferes. Elle forme des unites familiales composees d'un couple dominant et des jeunes issus de portees successives. Apres une etude de faisabilite, l'utilisation des poils comme materiel biologique et des microsatellites comme outil genetique a permis d'etudier le systeme d'appariement de la marmotte alpine en quantifiant les paternites extra-couples dans les groupes familiaux d'une population d

Abstract:

PART 1: Thirty-one medicinal plant species from Hawaii, Morocco, and the Sonoran Desert, USA have been shown in past studies to be highly inhibitory to pathogenic bacteria, fungi, and certain cancer cell lines. However, none were tested for antiviral activity. Acetone and methanol extracts from these species were bio-assayed for antiviral activity against herpes simplex virus types 1 and 2 (HSV 1 and HSV 2) and for cytotoxicity to the Vero C1008 cell line. Extracts from these species were tested in vitro for antiviral activity using an immunoperoxidase mini-plaque reduction assay to detect vir

UVC induced DNA adducts were cyclobutane pyrimidine dimmers (CPD) and 6-4 pyrimidine pyrimidone photoproducts (6-4PP). These adducts do not caused DNA breaks immediately, the DNA breaks were the intermediate of repair process that means conventional comet assay can’t estimate total amounts of UVC induced DNA adducts. To overcome this problem, people who demonstrated that damaged DNA was incubate with nuclear extract (NE) or T4 endonuc

Previous studies have shown that sodium arsenite (As3+), cigarette smoke extract (CSE), and methylglyoxal (MG) can significantly induced DNA damage, including 8-oxodG in different human cell lines. And, the intracellular reactive oxygen species (ROS) generation is mainly responsible for their induction of 8-oxodG. However, the suppression of OGG1 expression or activity by As3+, CSE and MG treatments are still unknown. Therefore, the purpose of this study was to determine the possib
