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).

Ultrasensitive assay uncovers hidden burden of tuberculosis disease

Researchers at Boston University have discovered an unexpectedly high prevalence of Mycobacterium tuberculosis DNA (TB DNA) in patients hospitalized in Boston, suggesting that tuberculosis disease may be significantly underdiagnosed in the United States.

New method boosts AI-driven protein engineering with massive data

Protein engineering is a field primed for artificial intelligence research. Each protein is made up of amino acids; to optimize a protein function, researchers modify proteins by switching out one of 20 different amino acids for another.

How next-generation proteomics is decoding the language of life

This review examines how next-generation protein sequencing and analysis technologies are expanding proteomics beyond the limits of mass spectrometry, especially for detecting proteoforms and analyzing proteins at single-molecule resolution. It highlights maturing fluorescence-based and nanopore-based platforms that could complement existing methods and deepen insight into protein sequence, structure, function, and modification states.

Targeting super-enhancer mechanisms offers new strategies for cancer therapy

Super-enhancers (SEs) are large clusters of transcriptional regulatory elements that drive oncogene expression, maintain malignancy, and create "transcriptional addiction" in cancer.

Protein complex cohesin found essential for guiding cell identity decisions

Temporarily disabling a protein complex that organizes DNA into loops inside the cell's nucleus drastically disrupted the three-dimensional structure of the genome, but surprisingly most genes continued to function as usual, Weill Cornell Medicine researchers found.

Lab study shows cigarette smoke damaged lung cells more than e-cigarette vapor

Researchers found that cigarette smoke extract disrupted the lung cell barrier, increased IL-6 inflammation, and caused DNA damage in Calu-3 cells, while e-cigarette vapor extract showed no significant adverse effects on these measures under the study conditions. The authors caution that these were in vitro findings using liquid extracts and unflavored e-liquid, so they do not directly predict long-term human health outcomes.

Damon Runyon supports young scientists driving cancer research innovation

The Damon Runyon Cancer Research Foundation has named 13 new Damon Runyon Fellows, exceptional postdoctoral scientists conducting basic and translational cancer research in the laboratories of leading senior investigators.

PRRDetect algorithm could one day revolutionize the treatment of cancer

Researchers have created a "metal detector" algorithm called PRRDetect to hunt down vulnerable tumors, in a development that could one day revolutionize the treatment of cancer.

Non-clinical safety assessment crucial for CRISPR-based gene therapies

The rapid evolution of CRISPR/Cas genome editing has redefined the possibilities of cellular and gene therapy, enabling precise correction, disruption, and regulation of disease-associated genes.

Early epigenetic changes shape infant gut microbiome development

The gut microbiome and epigenetics-molecular switches that turn genes on or off-are intertwined, and both contribute to neurodevelopment, finds a study publishing April 10 in the Cell Press journal Cell Press Blue.

New PCR method enables full genome amplification of HPV16

Human papillomavirus (HPV) is a double-stranded circular DNA virus with a genome of approximately 7–8 kb. This study aimed to establish an overlapping extension polymerase chain reaction method for the amplification of the entire genome of HPV16.

Low oxygen triggers regenerative programs in mammalian limb cells

Some animals can regrow lost body parts. Salamanders and frog tadpoles can rebuild entire limbs after amputation. Mammals cannot. For decades, biologists have tried to understand why.

Vibrio cholerae acquires antiviral defenses through horizontal gene transfer

Like most bacteria, Vibrio cholerae lives under constant attack from viruses. To survive, bacteria equip themselves with antiviral immune systems.

Study maps DNA methylation changes driving MDS stem cell dysfunction

Published on April 01, 2026, in Volume 2, article number 19 of the journal Immunity & Inflammation, a collaborative team led by Prof. Cao at the Institute of Basic Medical Sciences, Chinese Academy of Medical Sciences, along with Dr. Liangding Hu at the Fifth Medical Center of Chinese PLA General Hospital, and Professors Qian Zhang and Yanmei Han at the National Key Laboratory of Immunity and Inflammation, Naval Medical University, has generated the first base-resolution DNA methylome of human MDS HSCs.
