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).

Thrombosis with thrombocytopenia syndrome rare but serious adverse event associated with Ad26.COV2.S vaccination

A recent study conducted in the United States has revealed that thrombosis with thrombocytopenia syndrome following adenoviral vector-based coronavirus disease 2019 (COVID-19) vaccination is a rare event.

Researchers develop a highly efficient method to generate immune cells for cancer therapies

A Ludwig Cancer Research study has devised a highly efficient method to generate large numbers of immune cells specifically engineered to recognize neoantigens-;small fragments of randomly mutated proteins that are typically unique to a patient's cancer-;and destroy the tumors that express them.

Histone mimicry as a mechanism through which SARS-CoV-2 disrupts host cell epigenetic regulation

A recent study investigates histone mimicry as a mechanism by SARS-CoV-2 for disrupting epigenetic regulation to evade host cell responses to infection.

Study finds beneficial and harmful short-term health effects of caffeinated coffee consumption

Drinking caffeinated coffee appears to have both beneficial and harmful short-term health effects: increased abnormal heartbeats, increased physical activity and reduced sleep duration, according to late-breaking research presented today at the American Heart Association's Scientific Sessions 2021.

Lamin C important for keeping cell’s genetic material organized, research shows

In a study with lab-grown mouse cells, Johns Hopkins Medicine researchers say they have found that a protein that helps form a structural network under the surface of the cell's "command center" — its nucleus — is key to ensuring that DNA inside it remains orderly.

Stem cell enlargement contributes to decline in normal function during aging

MIT biologists have answered an important biological question: Why do cells control their size? Cells of the same type are strikingly uniform in size, while cell size differs between different cell types. This raises the question of whether cell size is important for cellular physiology.

Researchers identify gene expression involved in cancer progression and chemotherapy resistance

Even within a single patient with cancer, there is a vast diversity of individual tumor cells, which display distinct behaviors related to growth, metastasis, and responses to chemotherapy.

Study highlights the need for caution while using CRISPR-based gene therapies

A comprehensive study-;conducted by researchers at Sanford Burnham Prebys, the National Cancer Institute (NCI) and other groups-;has shown that gene editing, specifically gene knockout (KO), with CRISPR -Cas9 can favor cells with mutated forms of genes linked to cancer.

Urothelial cancers in Lynch Syndrome patients can be detected using a simple, cheap urine test

Researchers have shown for the first time that it is possible to detect signs of urothelial cancer using a simple, postal, urine test in Lynch Syndrome (LS) patients who are at high risk of developing tumors.

KHN’s ‘What the Health?’: Why health care is so expensive, chapter $22K

Congress appears to be making progress on its huge social spending bill, but even if it passes the House as planned the week of Nov. 15, it's unlikely it can get through the Senate before the Thanksgiving deadline that Democrats set for themselves.

New computer program can read any genome sequence and decipher its genetic code

Yekaterina "Kate" Shulgina was a first year student in the Graduate School of Arts and Sciences, looking for a short computational biology project so she could check the requirement off her program in systems biology. She wondered how genetic code, once thought to be universal, could evolve and change.
