СПОСОБ ДЕТЕКЦИИ ВАРИАНТА ПОСЛЕДОВАТЕЛЬНОСТИ НУКЛЕИНОВОЙ КИСЛОТЫ С ПОМОЩЬЮ АНАЛИЗА ТЕРМИНАЦИИ СО СДВИГОМ

Номер: RU2200762C2

Изобретение относится к молекулярной биологии и может быть использовано для выявления любой мутации в заданном сайте, известной последовательности нуклеиновой кислоты. В основе способа лежит принцип достройки затравки, комплементарной последовательности анализируемого образца, непосредственно примыкающей к нуклеотиду - мишени. При этом в реакционную смесь для достройки затравки вводят терминаторный нуклеотид того типа, который комплементарен нуклеотиду мишени в составе матрицы (указанный тип нуклеотида также может отсутствовать в реакции), и нуклеотиды трех других типов, которые не являются терминаторными и несут выявляемую метку. Прекращение реакции вследствие включения терминаторного нуклеотида свидетельствует об отсутствии мутации в исследуемом сайте; продолжение наращивания цепи за счет меченых нетерминаторных нуклеотидов - о ее наличии. Способ обеспечивает возможность простого, быстрого и экономичного определения мутаций любого типа. 35 з.п. ф-лы, 4 ил., 6 табл.

Adenylation Enzyme Inhibitors

Номер: US20170327549A1

The present invention concerns compounds that are capable of covalently entrapping adenylating enzymes. The present invention is essentially based on the discovery that analogues of adenylating enzyme (AE) substrates, wherein a methylene group has been incorporated at the carbon atom in the α-position relative to the carboxylate group involved in the adenylation, are capable of undergoing the adenylation reaction, thereby creating an activated methylene group in situ. The resulting ‘armed’ acyladenylate can interact with the enzyme resulting in covalent entrapment. Interestingly, the acyladenylate can alternatively be transferred to the next step in the enzyme cascade, following which the activated methylene group can interact with the next (active site cysteine containing) enzyme in the enzymatic cascade. The AE substrate analogues, based on their capability of ‘entrapping’ the respective enzymes, will have utility as activity based probes in biological research and also as diagnostic and/or therapeutic agents. 3. The adenylating enzyme (AE) substrate analogue according to claim 1 , wherein the capability of the compound binding to an adenylating enzyme (AE) is established using a competition binding assay claim 1 , wherein an ICvalue of less than 10 μM is indicative of said capability of binding to an adenylating enzyme (AE).5.

The invention relates to the use of a reverse-transcriptase inhibitor in the prevention or treatment of a degenerative disease. 1. A method of treating or preventing a degenerative disease in a subject in need thereof , the method comprising administering a therapeutically effective amount of a reverse transcriptase inhibitor to the subject.2. The method of claim 1 , wherein the reverse transcriptase inhibitor is a nucleoside inhibitor.3. The method of claim 2 , wherein the degenerative disease is linked to aging or oxidative stress.4. The method of claim 3 , wherein the degenerative disease is a neurodegenerative disease.5. The method of claim 4 , wherein the degenerative disease is selected from the group consisting of Parkinson's disease claim 4 , Alzheimer's disease claim 4 , Huntington's disease claim 4 , amyotrophic lateral sclerosis (ALS) claim 4 , degenerative diseases affecting eyesight and degenerative diseases affecting hearing.6. The method of claim 5 , wherein the degenerative disease is glaucoma. The present invention relates to the use of a reverse transcriptase inhibitor in the prevention and treatment of degenerative diseases.A characteristic of most degenerative diseases, in particular neurodegenerative diseases, is that they manifest late in life. This is true of both their sporadic and genetic forms, as is illustrated by Parkinson's disease, Alzheimer's disease and even the monogenetic Huntington's disease. This suggests that aging makes the cells more sensitive, even if the mutations themselves accelerating this aging cannot be ruled out.Oxidative stress, which mimics accelerated aging, generates reactive oxygen species (ROS) which are toxic, in particular in terms of the genome, where the chromatin proteins and the DNA bases are subjected to oxidation (Vijg, J., and Suh, Y., 2013). Reactive oxygen species may induce single-stranded and double-stranded (DSB) DNA breaks, thereby activating DNA damage response systems (O'Sullivan and Karlseder, ...

A homogeneous high throughput assay is described which screens compounds for enzyme inhibition, or receptor or other target binding. Inhibition (or binding) by the library compounds causes a change in the amount of an optically detectable label that is bound to suspendable cells or solid supports. The amounts of label bound to individual cells or solid supports are microscopically determined, and compared with the amount of label that is not bound to individual cells or solid supports. The degree of inhibition or binding is determined using this data. Confocal microscopy, and subsequent data analysis, allow the assay to be carried out without any separation step, and provide for high throughput screening of very small assay volumes using very small amounts of test compound.

Methods of Detecting Viability-Associated Molecules

Номер: US20090215047A1
Принадлежит: Iseao Tech Ltd

A method of detecting a molecule associated with viability of one or more cells or organisms in a sample comprises the initial step of contacting the sample with an enzyme, which enzyme is capable of adding or removing a chemical moiety to or from a nucleic acid molecule in the presence of the molecule associated with viability of the of the one or more cells or organisms. This thereby generates a novel detectable nucleic acid molecule. The next step involves detecting the presence of the molecule associated with viability of the one or more cells or organisms by detecting the novel nucleic acid molecule generated only in the presence of the molecule associated with viability of the one or more cells or organisms. A most preferred molecule associated with viability is ATP, although NAD may also be detected. A preferred enzyme for use in the methods is ligase. The method has numerous applications, in particular in monitoring viability of cells, toxicology testing and determining whether there is contamination in a sample or on a surface. Kits are also provided for carrying out the methods.

Ubiquitin ligases, and uses related thereto

Номер: CA2231645A1
Принадлежит: Individual

The present invention relates to the discovery in eukaryotic cells of ubiquitin ligases. These proteins are referred to herein collectively as "pub" proteins for Protein UBiquitin ligase, and individually as hpub1, h-pub2, h-pub3 and s-publ for the human pub1, pub2 and pub3 and Schizosaccharomyces pombe pub1 clones, repectively. Pub1 proteins apparently play a role in the ubiquitination of the mitotic activating tyrosine phosphatase cdc25, and thus they may regulate the progression of proliferation in eukaryotic cells by activating the cyclin dependent kinase complexes. In S. pombe, disruption of s-pub1 elevates the level of cdc25 protein in vivo increasing the activity of the tyrosine kinases, weel and mik1, required to arrest the cell-cycle. Loss of weel function in an S. pombe cell carrying a disruption in the s-pub1 gene results in a lethal premature entry into mitosis; such lethal phenotype can be rescued by the loss of cdc25 function. A ubiquitin thioester adduct of s-pub1 can be isolated from S. pombe and disruption of s-pub1 dramatically reduces ubiquitination of cdc25.
