Mutations in PLK4, encoding a master regulator of centriole biogenesis, cause microcephaly, growth failure and retinopathy

Andrew Jackson, Peter Nürnberg and colleagues identify mutations in PLK4 and TUBGCP6 in individuals with microcephaly, primordial dwarfism, retinopathy and other congenital anomalies. These findings ...

PIAS4 is associated with macro/microcephaly in the novel interstitial 19p13.3 microdeletion/microduplication syndrome

A syndrome of congenital microcephaly, intellectual disability and dysmorphism with a homozygous mutation in FRMD4A

Compound heterozygous BRAT1 mutations cause familial Ohtahara syndrome with hypertonia and microcephaly

Brain develops abnormally over lifespan of people who stutter

(University of Alberta) The largest-ever MRI imaging study of stuttering is the first to examine brain changes across the lifespan, says UAlberta researcher and ISTAR executive director.

Prolonging lifespan: Researchers create 'Methuselah fly' by selecting best cells

Scientists have managed to considerably prolong the lifespan of flies by activating a gene which destroys unhealthy cells. The results could also open new possibilities in human anti-aging research.

Ibuprofen leads to extended lifespan, study shows

COLLEGE STATION -- Regular doses of ibuprofen extended the lifespan of multiple species, according to research published in Public Library of Science-Genetics. "We first used baker's yeast, which is a...

New class of drugs dramatically increases healthy lifespan, mouse study suggests

Scientists have identified a new class of drugs that in animal models dramatically slows the aging process -- alleviating symptoms of frailty, improving cardiac function and extending a healthy lifesp...

Microcephaly-chorioretinopathy syndrome, autosomal recessive form. A case report.

The autosomal recessive form of microcephaly-chorioretinopathy syndrome is a rare genetic condition that is considered to be an important differential diagnosis with congenital toxoplasmosis.

PCH-2 regulates Caenorhabditis elegans lifespan.

Components or downstream targets of many signaling pathways such as Insulin/IGF-1 and TOR, as well as genes involved in cellular metabolism and bioenergetics can extend worm lifespan 20% or more. The ...

Mitochondrial and Cytoplasmic ROS Have Opposing Effects on Lifespan.

Reactive oxygen species (ROS) are highly reactive, oxygen-containing molecules that can cause molecular damage within the cell. While the accumulation of ROS-mediated damage is widely believed to be o...

Mutations in PLK4, encoding a master regulator of centriole biogenesis, cause microcephaly, growth failure and retinopathy.

Centrioles are essential for ciliogenesis. However, mutations in centriole biogenesis genes have been reported in primary microcephaly and Seckel syndrome, disorders without the hallmark clinical feat...

Plasticity of lifespan: a reaction norm perspective.

It is a well-appreciated fact that in many organisms the process of ageing reacts highly plastically, so that lifespan increases or decreases when the environment changes. The perhaps best-known examp...
