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).

Primate brain cell atlas provides molecular and cellular basis for neural circuit research

A team of nearly 100 scientists recently mapped the cell-type taxonomy in the macaque cortex and revealed the relationship between cell-type composition and various primate brain regions by using the self-developed spatial transcriptome sequencing technology Stereo-seq and snRNA-seq technology, which provides a molecular and cellular basis for further investigation into neural circuits.

Combination therapy shows promise in treating advanced ER+ breast cancer

Advanced estrogen receptor-positive (ER+) breast cancer can be especially difficult to treat. A new study by researchers at Dartmouth Cancer Center led by Todd W. Miller, PhD, shows promise in using a combination of estrogen and a PARP inhibitor (a drug that suppresses DNA damage repair), to treat this type of cancer.
