DNA News and Research

RSS

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).

EKF Molecular Diagnostics collaborates with ANGLE for liquid biopsy development using Parsortix and PointMan technologies

EKF Molecular Diagnostics has agreed a collaboration with specialist medtech company ANGLE plc, to investigate the combination of ANGLE's Parsortix circulating tumour cell (CTC) harvesting platform with EKF Molecular's PointMan™ DNA enrichment technology as a liquid biopsy. If successful, the resulting simple blood test could enable the investigation of unexpected ultra-low level mutations in a patient's cancer for personalised cancer care.

Hutchinson-Gilford Progeria Syndrome can be compared to normal aging, say scientists

In a new research study, scientists from Vision Genomics, LLC, Insilico Medicine, Inc., and Howard University showed that Hutchinson-Gilford Progeria Syndrome (HGPS or Progeria) is comparable to normal aging with respect to cellular signaling pathways, and that HGPS truly recapitulates the normal aging process.

Androgen receptor in prostate cancer cells can activate different gene set when bound to antiandrogens

The androgen receptor in prostate cancer cells can activate different sets of genes depending on whether it binds with an androgen hormone or an antiandrogen drug, according to a new study led by researchers at The Ohio State University Comprehensive Cancer Center - Arthur G. James Cancer Hospital and Richard J. Solove Research Institute.
