Even the growth and development of every living organism depends on the growth and multiplication of its cells. (studyinnovations.com)

Some of these mutations can lead to the development of mitochondrial diseases. (scitechdaily.com)
Such hereditary metabolic diseases can appear at any age, but the earlier the mutation manifests itself, the more likely it is to lead to severe symptoms and even death. (scitechdaily.com)
Overexpression of growth factors or a lack of suppressor proteins can lead to rapid uncontrolled cell division. (github.io)
In occasional cells, this crossing over may lead to increased 12p copy number and overexpression of cyclin D2. (medscape.com)

As a next step, researchers could for example use the organoids to test different treatment options and see which cells respond and which do not," De Barbanson adds. (hubrecht.eu)
At most 90% of the mtDNA was subject to mutation, the researchers discovered. (scitechdaily.com)

The addition of phosphate groups is a common mechanism used by cells to turn enzymes on and off. (nih.gov)

Cancers are named for the area in which they begin and the type of cell they are made of, even if they spread to other parts of the body. (healthline.com)
Human immunodeficiency virus (HIV) infection results from 1 of 2 similar retroviruses (HIV-1 and HIV-2) that destroy CD4+ lymphocytes and impair cell-mediated immunity, increasing risk of certain infections and cancers. (msdmanuals.com)

1. Understand the structure and function of the principal components and organelles of mammalian cells and microbes. (northumbria.ac.uk)
In the most well characterized "canonical" pathway in mammalian cells, the Notch intracellular domain (NotchIC) translocates to the nucleus where it mostly associates with the recombination signal binding protein for the immunoglobulin kappa J region (RBPJκ). (molvis.org)

If the damage cannot be accurately fixed, the cell may commit cellular suicide rather than lose control of growth. (nih.gov)

In the mammalian genome, this group of proteins assembles at tens of thousands of sites all at once, ensuring each chromosome is copied precisely once per cell division. (cshl.edu)
T-antigen hijacks other proteins from the infected cell to replicate the virus genome. (cshl.edu)
To replicate the genome once and only once per cell division, there are many feedback loops, checks, and balances. (cshl.edu)
It emerges from mutations and other pathological changes in the genome of a cell, leading this cell and its descendants to misbehave (Vogelstein and Kinzler 2004). (bbvaopenmind.com)

T, confers a proliferative advantage to neoplastic cells. (biomedcentral.com)

Subsequently, activated ATM then migrates to sites of DNA damage and phosphorylates other proteins that are necessary for halting the cell cycle and repairing DNA damage. (nih.gov)

Embryo morphology al ows options, the discovery of cell-free DNA in the evaluation of its growth, viability, and biological fluids has led to major advances in implantation capacity. (who.int)

One particular hypothesis, about an apobec mutation is assessed and a few - moderately weak - evidence for affiliation is seen. (giladhirschberger.com)
