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.

Novel palladium compound acts against ovarian tumor cells

A group led by a researcher affiliated with the University of São Paulo's São Carlos Chemistry Institute (IQSC-USP) in Brazil has developed a novel palladium compound that acts against ovarian tumor cells without affecting healthy tissues. Palladium is a silvery white metal belonging to the same group as platinum.

Inexpensive drug may be used to counteract treatment resistance in patients with leukemia

A common and inexpensive drug may be used to counteract treatment resistance in patients with acute myeloid leukemia, one of the most common forms of blood cancer.

New molecular mechanism can reverse genetic defect responsible for Friedreich's ataxia

Scientists at Tufts University have identified a molecular mechanism that could reverse the genetic defect responsible for Friedreich's ataxia, a neurodegenerative disease that leaves its victims with difficulty walking, a loss of sensation in the arms and legs and impaired speech caused by degeneration of nerve tissue in the spinal cord.

Research shows how the hepatitis D virus copies itself

A team of researchers has discovered how one crucial step occurs in the lifecycle of the hepatitis D virus (HDV), which causes the widespread and hard to treat liver inflammation called hepatitis D. The study, which was published recently in the Journal of Virology, could help develop antiviral therapy to control this disease.

Crick study reveals vital protective role of telomere t-loops

Loops at the ends of telomeres play a vital protective role preventing irretrievable damage to chromosomes, according to new research from the Crick.

Study presents a new view on how mitochondrial dysfunction may contribute to aging

Disturbances in the function of mitochondrial DNA can accelerate the aging process in ways that are different than previously thought, according to a new Finnish study published in Nature Metabolism.

The atomic-level structure of DNA polymerase delta – the enzyme behind DNA replication

A new study has revealed how the fundamental enzyme called DNA polymerase delta operates during DNA replication, making a copy of the genetic code that can be transmitted through the generations.

UCR biochemist receives grant to develop novel lead compound to treat breast cancer

A biochemist at the University of California, Riverside, has received a grant from the Congressionally Directed Medical Research Programs, or CDMRP, of the U.S. Department of Defense to develop a novel lead compound to treat breast cancer, the second most commonly diagnosed cancer among American women.

New mechanism that controls DNA repair identified

Deoxyribonucleic acid (DNA), is the macromolecule that holds all hereditary and genetic information. Continuously under assault, alterations and damage to DNA can lead to many different health issues, including cancer.

Discovery of neoantigens could widen the possibilities for universal cancer vaccine

For more than a decade, scientist Stephen Albert Johnston and his team at Arizona State University's Biodesign Institute have pooled their energies into an often scoffed-at, high-risk, high-reward goal in medicine: to develop a universal vaccine to prevent cancer.

Study on gene mutations may lead to better diagnosis and treatment for cancer

When a cell divides into two daughter cells, it must replicate its DNA according to a very specific scenario. In the presence of some disruptive elements, however, cancer cells are unable to perform this operation optimally; replication then takes place more slowly and less efficiently.

New study reveals 'clutch' proteins responsible for putting T cell activation 'into gear'

In collaborative research, scientists from three continents were able to discover a crucial bit of information about how T cells move proteins inside them to drive the immune response. This could help evolve specific new treatments centered on T cell selectivity.

Novel anticancer agents show promise to control tumor growth in nearly every cancer type

A gene called MYC has become one of the hottest targets for cancer researchers around the world. MYC is known to drive tumor growth in nearly all cancer types - but successfully targeting the gene has proven to be a challenge.

Study uncovers new way to identify driver genes important for cancer progression

Until now, researchers believed recurrent mutations (hotspot mutations) in cancer tumors were the important mutations (driver mutations) that promoted cancer progression.

Study shows how SIRT1 plays key role in maintaining the regenerative potential of leukemic stem cells

Patients with chronic myeloid leukemia can be treated with tyrosine kinase inhibitors. While these effective drugs lead to deep remission and prolonged survival, primitive leukemia stem cells resist elimination during the remission and persist as a major barrier to cure.
