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.

Scientists discern molecular mechanisms underlying plant parasitism, cross-species grafting

Using the model Orobanchaceae parasitic plant Phtheirospermum japonicum, scientists from Nagoya University and other research institutes from Japan have discerned the molecular mechanisms underlying plant parasitism and cross-species grafting, pinpointing enzyme β-1,4-glucanase (GH9B3) as an important contributor to both phenomena.

'Synthetic lethality' could be exploited for cancer therapy

A Ludwig Cancer Research study has identified a new instance in which the simultaneous mutation of two nonessential genes--neither of which is on its own vital to cell survival--can cause cancer cell death.

Exploiting 'synthetic lethality' to identify cancer targets

With advances in genome sequencing, cancer treatments have increasingly sought to leverage the idea of "synthetic lethality," exploiting cancer-specific genetic defects to identify targets that are uniquely essential to the survival of cancer cells.

Glitches in DNA replication have important implications for treating cancer

USC researchers peering deep inside a living cell have discovered something surprising: Its system for preventing genetic damage linked to diseases can fail so badly that the cell would be better off without it.

ACE2 and pattern recognition receptor genes increase with age

A recent study by researchers in California and published on the preprint server bioRxiv* in June 2020 shows that advancing age is associated with increased expression of pattern recognition receptor (PRR) genes and ACE2 receptors, possibly accounting in part for the increased severity of the disease in older adults.

Plasmodium parasites have timekeeping systems that maintain their cell cycle activities

The parasites responsible for malaria seem to march to their own beat.The mystery behind the molecular basis of how these parasites synch their rhythm in replication to the host's clock-driven rhythms has been solved.

New insights on DNA replication can help develop novel cancer treatments

A study by the Centre for Chromosome Biology at NUI Galway, Ireland, in partnership with the University of Zurich, has uncovered new insights into how the replication of DNA occurs which can be applied to help develop novel cancer treatments.

Study resolves contradictions surrounding p53 gene's role in pluripotent stem cell differentiation

The gene p53 is extremely important in cell biology and, hence, the world of cell replacement therapy. Its role is to regulate the cell cycle and halt the formation of tumors, leading to its nickname the "tumor suppressor gene."

Scientists uncover important functions of a special protein during cell division

In a new study, researchers from the University of Copenhagen have discovered two important functions of a protein called RTEL1 during cell division.

Antibiotic exposure and its priming effect on disease-causing bacteria

Antibiotics save lives -- but using them also helps antibiotic-resistant strains evolve and spread. Each year, antibiotic-resistant bacteria infect some 2.8 million people in the United States, killing more than 35,000, according to the Centers for Disease Control and Prevention.

Researchers find direct link between MCL1 protein and cell-cycle checkpoint protein

Human cells respond to stresses like DNA damage, metabolic imbalance and starvation by first trying to repair the problem.

Uncovering the Achilles' heel of cancer cells to find effective cures

The key to effective cures for cancers is to find weak points of cancer cells that are not found in non-cancer cells.

Researchers elucidate new mechanism for controlling DNA methylation in cells

Why normal cells turn into cancer cells One of the factors is deeply related to the failure of the cell differentiation mechanism called DNA methylation.

NYU Abu Dhabi researchers develop nanocarrier for more effective cancer drug delivery

A team of researchers at NYU Abu Dhabi has developed a biocompatible, biodegradable, and economical nanocarrier for safer and more effective delivery of anticancer drugs.

Increased brain growth, mutations and autism linked in new study

Salk Institute researchers have now found a pattern of DNA damage that is unique to brain cells derived from individuals with a single form of autism spectrum disorder (ASD) called macrocephalic ASD. The study, published in the journal Cell Stem Cell in January 2020, may offer an explanation about the developmental misstep that caused this disease.
