A new theory of the origin of cancer: quantum coherent entanglement, centrioles, mitosis, and differentiation

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 - stil

Quantum Tunnelling to the Origin and Evolution of Life

Quantum tunnelling is a phenomenon which becomes relevant at the nanoscale and below. It is a paradox from the classical point of view as it enables elementary particles and atoms to permeate an energetic barrier without the need for sufficient energy to overcome it. Tunnelling is being of vital imp

Variation in cancer risk among tissues can be explained by the number of stem cell divisions

Tomasetti and Vogelstein show that the lifetime risk of cancers of many different types is strongly correlated with the total number of divisions of the normal self-renewing cells maintaining that tissue’s homeostasis. These results suggest that only a third of the variation in cancer risk among t

Key role found for enzymes in DNA replication and sensitivity to chemotherapeutic drugs

A new study shows that the TLK1 and TLK2 enzymes are critical for ensuring the copying of DNA. The research is based on previous studies that pointed to TLK1/2 as potential candidate targets in cancer therapy, and it provides new molecular details on their key functions in cancer cell proliferation.

Rhythm of DNA replication exploited to kill cancer cells

Human cells divide and create new cells throughout life. In this process, a steady — even rhythmic — supply of DNA building blocks is needed to create new DNA. Now researchers have shown exactly how human cells regulate this process so it does not fail and cause illness. The researchers also show how they can manipulate the rhythm and suggest how this can be used in the future to kill cancer cells. (Mehr in: Cancer News — ScienceDaily)

The ‚DNA corrector‘ is more efficient in the most important regions of the genome

Error surveillance and repair mechanisms during DNA replication do not show the same competence in all regions of the human genome. Scientists have discovered that the mechanism that repairs errors in DNA is more efficient in the regions of genes that hold information for the production of proteins.

Problems with DNA replication can cause epigenetic changes that may be inherited for several generations

Scientists reveal that a fault in the process that copies DNA during cell division can cause epigenetic changes that may be inherited for up-to five generations. They also identified the cause of these epigenetic changes, which is related to the loss of a molecular mechanism in charge of silencing genes. Their results will change the way we think about the impact of replication stress in cancer and during embryonic development, as well as its inter-generational inheritance.

DNA Replication – Take a break

Before a cell divides, it must first handle a large-scale project: Its entire genetic material has to be duplicated so that each of the two daughter cells is equipped with a full copy after cell division. As errors in this DNA replication could lead to the death of the cell, the process is rigorously controlled. It takes place in two phases. Researchers at the Max Planck Institute of Biochemistry in Martinsried have now revealed in the journal Cell Reports that these two phases are strictly separated from one another by breaks, thereby preventing errors in the DNA replication.

Chromosomes: the importance of keeping the balance

The genetic material of cancer cells is unstable. For example, the number of chromosomes, which are the individual elements of packed DNA, is changed in so called aneuploidies. This imbalance in chromosomes, which often occurs early in tumor development, leads to cell stress and promotes disease. How this can happen is now shown by the discovery of a research team led by Zuzana Storchová at the Max Planck Institute of Biochemistry in Martinsried, reported in a groundbreaking study published in Nature Communications. An imbalance in an enzyme called MCM2-7 that is essential for DNA replication is likely to be responsible […]

Researchers connect haywire protein to breast cancer, leukemia

The cause of some cancers, including breast cancer and leukemia, is better understood, thanks to recent research. In the new study, the researchers found that too much of a key protein, called cyclin E, slows down DNA replication and introduces potentially harmful cancer-linked mutations when cells divide.

New CRISPR technique skips over portions of genes that can cause disease

16. Aug. 2018

In a new study in cells, researchers have adapted CRISPR gene-editing technology to cause the cell’s internal machinery to skip over a small portion of a gene when transcribing it into a template for protein building. Such targeted editing could one day be useful for treating genetic diseases caused by mutations in the genome, such as Duchenne’s muscular dystrophy, Huntington’s disease or some cancers.
