DNA, or deoxyribonucleic acid, is the hereditary material in humans and almost all other organisms. Nearly every cell in a person’s body has the same DNA. Most DNA is located in the cell nucleus (where it is called nuclear DNA), but a small amount of DNA can also be found in the mitochondria (where it is called mitochondrial DNA or mtDNA).

Diet-derived molecules identified as main drivers of young-onset colorectal cancer risk

A new Cleveland Clinic study has identified diet-derived molecules called metabolites as main drivers of young-onset colorectal cancer risk, especially those associated with red and processed meat.

Study reveals a paradigm shift in the understanding of T-lineage acute lymphoblastic leukemia

Researchers at Children's Hospital of Philadelphia (CHOP), St. Jude Children's Research Hospital (St. Jude) and the Children's Oncology Group (COG) today announced a significant paradigm shift in the understanding of T-lineage acute lymphoblastic leukemia (T-ALL), an aggressive and high-risk form of cancer, to one frequently driven by genetic changes in non-coding portions of our DNA.

Study reveals how chromatin structure influences social behavior in dogs

A new study on dogs found that chromatin's spatial structure has a significant role in the evolution of social behavior.

Mrc1 protein identified as key to maintaining cell identity during division

In a major scientific breakthrough, researchers have found that a protein called Mrc1 plays a crucial role in ensuring that cells keep their identity as they divide and grow.

Study suggests maternal adverse childhood experiences may become biologically embedded

Researchers investigated the transfer of biological embedding of life experience across generations by evaluating traumatic childhood experiences of mothers and epigenetic clocks in pregnant mothers and their newborn offspring.

Researchers develop new method to study critical type of protein modification process

Human proteins undergo a variety of chemical modifications following their synthesis. These modifications regulate their structure, function, and stability.

New research identifies key protein complex in cellular quality control

Anyone who's tried to neatly gather a fitted sheet can tell you: folding is hard. Get it wrong with your laundry and the result can be a crumpled, wrinkled mess of fabric, but when folding fails among the approximately 7,000 proteins with an origami-like complexity that regulate essential cellular functions, the result can lead to one of a multitude of serious diseases ranging from emphysema and cystic fibrosis to Alzheimer's disease.

Researchers identify key genetic players in dopamine signaling using transparent worms With The Help Of A Tin...

Dopamine, a powerful brain chemical and neurotransmitter, is a key regulator of many important functions such as attention, experiencing pleasure and reward, and coordinating movement.

Prenatal BPA exposure tied to autism risk in boys

Study reveals that prenatal exposure to BPA disrupts aromatase activity in male brains, potentially leading to autism-like symptoms. Treatment with 10-HDA shows promise in reversing these effects.

Enzyme blockade improves memory updating in older mice

Everyone has moments of forgetfulness from time to time, especially as we get older. But older adults don't just have difficulty remembering new information.

New insights into retrotransposon-derived DNA zip codes in myeloma cells

A new editorial was published in Oncoscience (Volume 11) on July 13, 2024, entitled, "Unveiling retrotransposon-derived DNA zip code for myeloma cell internalization."

DeepPBS: A geometric AI model for accurate prediction of protein-DNA binding specificity

A new artificial intelligence model developed by USC researchers and published in Nature Methods can predict how different proteins may bind to DNA with accuracy across different types of protein, a technological advance that promises to reduce the time required to develop new drugs and other medical treatments.

Breakthrough study uncovers TIP60’s role in DNA access and disease mechanisms

To transcribe the information contained in our genes or to repair the dozens of breaks that occur daily in our DNA, our enzymes must be able to directly access the DNA to perform their functions.

Columbia study reveals bacteria create free-floating genes, challenging genetic code norms

Since the genetic code was first deciphered in the 1960s, our genes seemed like an open book. By reading and decoding our chromosomes as linear strings of letters, like sentences in a novel, we can identify the genes in our genome and learn why changes in a gene's code affect health.

New insights into topoisomerase I inhibition reveal potential pathways for cancer therapies

A research group at the University of Bologna has identified, for the first time, the specific location and genomic context where DNA breaks occur due to the inhibition of the topoisomerase I, a protein crucial for many biological processes in cells.
