DNA Replication News and Research

RSS

DNA replication, the basis for biological inheritance, is a fundamental process occurring in all living organisms to copy their DNA. This process is "semiconservative" in that each strand of the original double-stranded DNA molecule serves as template for the reproduction of the complementary strand. Hence, following DNA replication, two identical DNA molecules have been produced from a single double-stranded DNA molecule. Cellular proofreading and error-checking mechanisms ensure near perfect fidelity for DNA replication.

Research finds link between p53 pathway and ribosome biogenesis, nucleotide metabolism in DBA

Diamond Blackfan Anemia (DBA) is a condition that is characterized by a failure of the bone marrow to produce red blood cells, congenital abnormalities, and a predisposition to cancer.

Tufts scientists discover reason for incidence of genetic error that causes many disorders

Tufts University researchers have discovered a possible explanation for the occurrence of a genetic error that causes over a dozen neuromuscular and neurodegenerative disorders, including Huntington's disease, myotonic dystrophy and forms of spinocerebellar ataxia.

Fission yeast could help discover novel cancer drugs

Cancer is a notoriously difficult disease to treat. Not only do a wide variety of cancers exist, requiring specialized treatments for each type, but cancer cells within an individual can morph and render previously potent therapeutics ineffective.

Genome-wide studies reveal evolutionary conserved enzyme facilitates DNA replication

Genome-wide studies of fission yeast (Schizosaccharomyces pombe) suggest that the evolutionary conserved enzyme Pfh1 helicase facilitates DNA synthesis by tracking along with the replication apparatus, promoting intact DNA synthesis at hard-to-replicate sites and consequently suppressing DNA damage. The findings are published in PLOS Genetics.

Researchers uncover molecular differences between African and Asian strain of Zika virus infections

Scientists have revealed molecular differences between how the African and Asian strains of Zika virus infect neural progenitor cells.

Unexplained neurodevelopmental disorder linked to harmful mutations in SON gene

A neurodevelopmental disorder for which there was no known cause has been linked to SON, a gene that is involved in essential mechanisms a cell uses to translate DNA into protein, as well as in DNA replication and cell division.

Study reveals unexpected process for acquiring chemoresistance in breast cancers

A laboratory study has revealed an entirely unexpected process for acquiring drug resistance that bypasses the need to re-establish DNA damage repair in breast cancers that have mutant BRCA1 or BRCA2 genes.

Mutations in STN1 gene cause Coats plus syndrome

A team of Israeli researchers has discovered that mutations in STN1, a gene that helps maintain the ends of chromosomes, cause the rare, inherited disorder Coats plus syndrome.

Molecule thought to indicate good cancer prognosis can have dark side, research shows

A molecule which, for the last 20 years has been believed to be an indicator of good prognosis in tumours has been shown to have a dark side by new research from The Universities of Manchester, Athens and collaborators, recently published in Nature Cell Biology.

Diet experiments on Lynch syndrome mouse model may help in early detection of colon cancer

Colorectal cancer is the second most common cause of cancer-related deaths in the Western world, mainly because it is usually diagnosed too late. Finding ways to identify those people who are at increased risk of developing colon cancer is therefore crucial, a researcher will tell the annual conference of the European Society of Human Genetics today.

Changes in chromatin structure may promote cancer

Cancer development is a complex process involving both genetic and epigenetic changes. Genetic changes in oncogenes and tumor-suppressor genes are generally considered as primary causes, since these genes may directly regulate cellular growth. In addition, it has been found that changes in epigenetic factors, through mutation or altered gene expression, may contribute to cancer development.

Shugoshin protein maintains proper gene expression in subtelomeres

A research group discovered a new function of the chromosomal terminus, which may lead to the clarification of the mechanism for developing abnormal telomere structure such as multiple malformation and mental retardation.

UT Southwestern scientists discover mutation that causes X-linked reticulate pigmentary disorder

UT Southwestern Medical Center researchers have discovered a mutation that causes a rare systemic disorder known as X-linked reticulate pigmentary disorder (XLPDR) and, significantly, the unexpected cellular mechanism by which the mutation causes the disease.

Scientists provide overview of most promising compounds to combat prostate cancer

Scientists from MIPT (Moscow Institute of Physics and Technology), MSU (Moscow State University), and National University of Science and Technology “MISIS” provided an overview of the most promising compounds which can be used as medications for prostate cancer.

CNIO researchers find panoramic view of proteins that intervene in a cellular process

Three years ago, the research team directed by Óscar Fernández-Capetillo, head of the Genomic Instability Group at the Spanish National Cancer Research Centre, obtained, for the first time, a panoramic view of the proteins that intervene in one of the most important and delicate cellular processes: the copying of genetic material during cellular division. They observed that the parts of the genome where the DNA was copied were also very rich in the modification by some very particular proteins, SUMOylations, and poor in others, ubiquitinations, but they were unable to understand why.

Study on DNA scrunching may aid in developing new antimicrobial medicines

A research collaboration that combines novel "big-data" informatics tools with expertise in basic biology has uncovered details of an essential process in life: how a crucial enzyme locates the site on DNA where it begins to direct the synthesis of RNA. This finding may aid in the discovery of new antimicrobial medicines, and the powerful technological approaches developed for this research may shed light on other essential cellular processes.

Study identifies gene linked to rare, complex diseases

IRB Barcelona identifies GEMC1 as a master gene for the generation of multiciliated cells—cells with fine filaments that move fluids and substances—which are found exclusively in the brain, respiratory tract, and reproductive system.Defects in multiciliated cells lead to ciliopathies—rare and complex diseases that are poorly understood and for which not all causative genes have been identified.
