In rare cases, cancer treatments can cause serious long-term effects. These include so-called secondary leukemias. This form of blood cancer can develop when chemotherapy or radiotherapy damages the genetic material of healthy cells. A research team led by a scientist from Ulm has now discovered a molecular protective mechanism against such genomic damage: a peptide that can inhibit breaks in the DNA without compromising the curative effect of the actual cancer therapy. These findings could potentially help to make cancer treatments safer. The study was published in the renowned journal Nature Communications. Quelle: IDW Informationsdienst Wissenschaft

Researchers at the University of Bayreuth have, for the first time, deciphered key steps in the biosynthetic mechanism of the potential anti-cancer agent fostriecin. The team led by Prof. Dr. Frank Hahn has succeeded in producing all enzymes involved in the process in the laboratory and examining them individually under controlled conditions. In the long term, the findings may pave the way for more efficient production of the compound and open up new avenues in cancer therapy. The researchers have reported their findings in the renowned journal Nature Communications. Quelle: IDW Informationsdienst Wissenschaft Hier jetzt das aktuell Außergewöhnliche auswählen …

Muhammad A Shah, Emily L Denton, Cheryl H Arrowsmith, Mathieu Lupien and Matthieu Schapira Abstract Background The notion that epigenetic mechanisms may be central to cancer initiation and progression is supported by recent next-generation sequencing efforts revealing that genes involved in chromatin-mediated signaling are recurrently mutated in cancer patients. Results Here, we analyze mutational and transcriptional profiles from TCGA and the ICGC across a collection 441 chromatin factors and histones. Chromatin factors essential for rapid replication are frequently overexpressed, and those that maintain genome stability frequently mutated. We identify novel mutation hotspots such as K36M in histone H3.1, and uncover…

Low non-specific, low intensity laser illumination (635, 670 or 830 nm) apparently enhances centriole replication and promotes cell division, what is the opposite of a desired cancer therapy. In the contrary, centrioles are sensitive to coherent light. Then higher intensity laser illumination – still below heating threshold – may selectively target centrioles, impair mitosis and be a beneficial therapy against malignancy. If centrioles utilize quantum photons for entanglement, properties of centrosomes/centrioles approached more specifically could be useful for therapy. Healthy centrioles for a given organism or tissue differentiation should then have specific quantum optical properties detectable through some type of…
