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).

Why vaginal microbiota transplants aren’t working yet

Vaginal microbiota transplantation without antibiotics fails to restore microbiome balance, yet engraftment suggests avenues for enhancing treatment efficacy.

DNASE1L2 identified as a dynamic biomarker for TB progression

Tuberculosis (TB) remains one of the world's most serious public health threats, with approximately one-quarter of the global population infected with Mycobacterium tuberculosis. While most infections remain latent (LTBI), individuals with LTBI are at risk of progressing to active TB and potentially becoming new sources of transmission.

How gut imbalance may drive obesity, diabetes, and heart disease

A new review argues that gut dysbiosis is closely linked to metabolic dysfunction through intertwined effects on inflammation, oxidative stress, gut barrier integrity, microbial metabolites, and epigenetic regulation. It also highlights microbiome-targeted strategies such as high-fiber diets, probiotics, prebiotics, postbiotics, exercise, and fecal microbiota transplantation as promising ways to support metabolic health.

Chronic colitis reshapes colon stem cells in ways that can accelerate tumour growth

Researchers showed that chronic colitis leaves a long-lasting epigenetic memory in colonic stem cells, persisting for more than 100 days after recovery in mice. This memory is marked by durable AP-1-linked chromatin changes and later amplifies tumour outgrowth after oncogenic mutation.

Diverse biobank study links genetics to disease risk and treatment

A new study by UCLA Health published in Cell presents a major advancement in the future of personalized medicine by pinpointing new connections between people's genes, disease risk and medicine response by using a clinically well-characterized and diverse population-represented biobank.

New AI system maps gene expression across the whole body

Understanding gene expression within the body has been a boon for 21st century biology and therapeutics, but most discoveries that use these technologies only focus on one organ or one small area of tissue.

Molecular test shows high sensitivity in detecting bile duct cancer

When patients develop a narrowing or blockage in the bile ducts – the tubes connecting the liver, gallbladder and intestines – physicians must determine whether the cause is cancer or a benign condition.

Circulating tumor DNA predicts breast cancer relapse after treatment

Fragments of tumor DNA circulating in the bloodstream of patients with breast cancer can predict whether they are likely to relapse, especially when samples are taken after the patients have received treatments prior to surgery.

Obesity-driven organ enlargement may boost cancer risk

Scientists at City of Hope® and TGen (part of City of Hope) are the first to explain a major mechanism for why gaining excess weight increases your risk of cancer.

The new microchip electrophoresis system MultiNA II MCE-301- High sensitivity detection, improved analysis function and operability

Shimadzu has recently released the MultiNA II MCE-301 microchip electrophoresis system. By automating the entire process of electrophoresis, which takes more than two hours by hand (creation of gels, dispensing reagents, dispensing sample, separation, dyeing, cleaning of equipment), the company significantly improves the efficiency of genetic analysis operations.

Scientists discover how brain development programs fuel pediatric tumors

A team of researchers at Baylor College of Medicine, St. Jude Children's Research Hospital, Texas Children's Hospital, and collaborating institutions reveals in the journal Nature a novel mechanism that drives the development of pediatric supratentorial ependymoma (EPN), the third most common pediatric brain tumor. The findings suggest potential new approaches to treat these aggressive and chemo-resistant tumors.

New guidance aims to standardize tumor mutational burden in cancer

Immune checkpoint inhibitors have transformed cancer care, yet only a minority of patients respond to monotherapy, and immune-related adverse events remain a major concern.

Immunotherapy plus chemotherapy improves outcomes in stage III dMMR colon cancer

A new study from researchers at the Alliance for Clinical Trials in Oncology (Alliance) shows that patients with stage III colon cancer with deficient deoxyribonucleic acid (DNA) mismatch repair (dMMR) had significantly better outcomes when the immunotherapy drug atezolizumab (Tecentriq®) was added to standard chemotherapy after surgery.

Blood pressure drug boosts effectiveness of cancer therapy

In a new Dartmouth Cancer Center (DCC) study led by clinical researcher Tyler J. Curiel, MD, MPH, FACP, investigators found that the FDA-approved blood pressure drug telmisartan can significantly enhance the cancer-killing activity of the targeted therapy olaparib, potentially expanding its use to many more patients.
