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).

Studies show prognostic value for circulating tumor cells in advanced prostate and breast cancer

Menarini Silicon Biosystems, the pioneer of liquid biopsy and single cell technologies, announced today that results from a new study presented at the virtual 2020 meeting of the American Society of Clinical Oncology suggest that circulating tumor cell counts may be useful in determining long-term prognosis and guiding treatment selection in patients with metastatic castrate sensitive prostate cancer.

Study provides molecular explanation to a longstanding mystery in viral oncology

The oncogenic herpesvirus (HHV8 or KSHV) causes a cancer known as Kaposi's Sarcoma. An international team of scientists led by the University of Helsinki has discovered key factors that control the genome maintenance and replication of a virus responsible for lymphatic vascular cancer.

Deep UV LED inactivation of SARS-CoV-2 - fast and effective

The ongoing pandemic has aroused considerable effort to find methods to prevent and control the spread of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), which causes COVID-19 disease. Rapid inactivation devices would be of great help in this area, to prevent viral transmission through aerosols and contact with infected surfaces.

Researchers confirm new therapeutic target for myelodysplastic syndrome

A research group from Kumamoto University, Japan analyzed the pathophysiology of myelodysplastic syndrome (MDS), a blood cancer that presents often in the elderly, and found the presence of the transcription factor RUNX3, thereby revealing a cancer growth function for what had been considered a tumor suppressor.
