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.

UD researchers examine connection between DNA replication in HPV and cancer

A pair of researchers from the University of Delaware Department of Medical and Molecular Sciences are investigating genetic variations in DNA replication of human papillomaviruses and its correlation with HPV-related cancers.

Aravive Biologics demonstrates proof-of-mechanism for AVB-S6-500 in ongoing phase 1 study

Aravive Biologics, Inc. announced today that the company has demonstrated clinical proof-of-mechanism for AVB-S6-500 in neutralizing GAS6, based on analysis of the single ascending dose portion of the ongoing Phase 1 study.

Findings confirm analytical principle that describes mutational processes and cancer development

When a cell develops into a tumor, something has gone terribly wrong: the uncontrolled growth, invasion of nearby tissues and finally metastasis are the result of many consecutive DNA mutations.

New class of drug holds potential to help patients with treatment-resistant cancers

Researchers have discovered a new class of drug that has the potential to help cancer patients who no longer respond to existing therapies.

Novel biomarker helps optimize anticancer therapy

Researchers have identified a biomarker that can be used to visualize blood vessel activity and optimize the timing of anticancer therapy.

Vascular stabilization biomarker helps optimize timing of anticancer therapies

Angiogenesis, the formation of new blood vessels, is essential for tumor growth. A new study reported in The American Journal of Pathology describes a vascular stabilization biomarker that can visualize blood vessel activity, thus optimizing the timing of anticancer therapies including anti-angiogenics.

Scientists uncover new answers to cell aging in children with rare, fatal disease

In a recent paper published in Cell Reports, Saint Louis University researchers have uncovered new answers about why cells rapidly age in children with a rare and fatal disease.

Study finds link between women having children and shorter telomeres

A recent study by George Mason University researchers in the Department of Global and Community Health found that women who have given birth have shorter telomeres compared to women who have not given birth.

Research shows how viruses inactivate immune system, causing cancer

It's no new news that viruses cause cancer. For example, human papillomavirus causes almost all of the more than 500,000 annual worldwide cases of cervical cancer.

Skin bacteria may be an answer to cancer find researchers

The skin protects the body from harm and is also covered with billions of bacteria which are called commensal bacteria that form the microbiota of the skin. These are friendly bacteria that stay on the skin surface without causing harm.

Quiescent cells also acquire particular type of mutation, research shows

For almost a hundred years, geneticists have believed that the more a cell divides the more mutations it acquires. However, research by scientists at the Institut Pasteur shows that quiescent cells, which do not divide, also acquire a particular type of mutation - deletions (mutations through loss of nucleobases).

Scientists target tumor suppressor as a new treatment approach to 'triple-negative' breast cancer

Researchers studying “triple-negative” breast cancer have found that the loss of a specific tumor suppressor provides clues about potential new treatments.

MIT researchers discover new way to make bacteria vulnerable to existing antibiotics

MIT researchers have discovered a way to make bacteria more vulnerable to a class of antibiotics known as quinolones, which include ciprofloxacin and are often used to treat infections such as Escherichia coli and Staphylococcus aureus.

Study shows how interplay between two key enzymes promotes brain tumor growth

Study results revealed previously unknown interplay between two key enzymes and a novel understanding of how brain cancer tumors form and spread, according to researchers at The University of Texas MD Anderson Cancer Center.

FSU researchers solve puzzle posed by family of rare premature aging disorders

New research from Florida State University is beginning to piece together the stubborn puzzle posed by a family of rare and debilitating premature aging disorders.

Researchers show how rhythm of DNA replication can be manipulated to kill cancer cells

Human cells divide and create new cells throughout life. In this process, a steady – even rhythmic – supply of DNA building blocks is needed to create new DNA. Now researchers from the University of Copenhagen are the first to show exactly how human cells regulate this process so it does not fail and cause illness.

IBN researchers create DNA technology with two new genetic alphabets

Just like how alphabets are strung together to form words, our DNA is also strung together by alphabets to encode proteins. Our DNA contains only 4 natural genetic alphabets - A, C, G and T, which hold the blueprint for the production of proteins that make our bodies work.

Research provides insight into how two stands of double helix separate during replication

Life would be impossible if the DNA in dividing cells were replicated with anything less than near-perfect precision. Every time a nucleated cell commits to becoming two cells, every "letter" of its genome must be replicated once and only once.

Study helps understand basic mechanisms of mitochondrial DNA maintenance

Researchers at the University of Eastern Finland have discovered a novel mechanism safeguarding mitochondrial DNA. The study, published in PNAS earlier this week, was carried out in close collaboration with research groups from CBMSO in Madrid, Spain, and Umeå University in Sweden.

New test identifies antibiotic-resistant bacteria in 30 minutes

The discovery of antibiotics in the early part of the 20th century changed modern medicine. Simple infections that previously killed people became easy to treat. Antibiotics' ability to stave off infections made possible routine surgeries, organ transplants, and chemotherapy for the treatment of cancer.
