Stem cell transplantation benefits mice with childhood motor neuron disease
EurekAlert! Tue, 02 Sep 2008 2:19 PM PDT
The motor neuron disease spinal muscular atrophy (SMA) is the second most common genetic disorder leading to death in childhood. There is currently no cure for SMA, but some clinicians and researchers consider stem cell transplantation as a potential therapeutic strategy. And now, work using a mouse model of SMA suggests that spinal cord neural stem cells might be a possible treatment for ...

A tal(in) of cell spreading pp1017 - 1019
Talin can activate integrins to bind the extracellular matrix and also
connect matrix-engaged integrins to the actin cytoskeleton. New work
shows that cell spreading can be dissected into three distinct phases
according to their differential requirements for talin function.

Prion: disease or relief? pp1019 - 1021
The self-perpetuating amyloid isoform, or prion, of the yeast translation
termination factor eRF3 modulates programmed translational
frameshifting that controls a regulatory circuit determining the polyamine

Twisted epithelial-mesenchymal transition blocks senescence pp1021 - 1023
The epithelial-mesenchymal transition (EMT) is a cellular transdifferentiation
program that enables epithelial cancer cells to acquire traits of high-grade
malignancy, notably invasive and metastatic powers. A new study indicates
that it may also function early in tumour progression by preventing
oncogene-induced senescence.

Identification of genes that regulate epithelial cell migration using
an siRNA screening approach pp1027 - 1038
A siRNA screen in mammalian epithelial cells uncovers 42 genes
not previously implicated in migration or adhesion. Many genes are
involved in beta-catenin, beta1-integrin and actin signaling.
Genes that accelerate migration tend to impair adhesion.

Actin and alpha-actinin orchestrate the assembly and maturation
of nascent adhesions in a myosin II motor-independent manner pp1039 - 1050
Adhesion assembly is needed for cell migration. Horwitz and colleagues
report that new adhesions assemble in the lamellipodium in a manner
that is independent of myosin II but requires actin polymerization.

Talin depletion reveals independence of initial cell spreading from
integrin activation and traction pp1062 - 1068
Talins link integrins to the actin cytoskeleton and are important for
cell spreading. Sheetz and colleagues show that talin is dispensable
for initial cell spreading but it is required for sustained cell
spreading and adhesion.

Epigenetic control of polyamines by the prion [PSI+] pp1069 - 1075
Namy et al. show that the yeast prion form of the eERF3 translation

Plk1-dependent phosphorylation of FoxM1 regulates a transcriptional
programme required for mitotic progression pp1076 - 1082
The kinase Plk1 regulates multiple processes during mitosis in mammalian

phosphorylation of the transcription factor FoxM1

The adaptor protein of the anaphase promoting complex Cdh1 is essential
in maintaining replicative lifespan and in learning and memory pp1083 - 1089
Cellular progression through mitosis is largely controlled by the APC-Cdh1

p53 mRNA controls p53 activity by managing Mdm2 functions pp1098 - 1105
The ubiquitin ligase Mdm2 promotes both proteolytic degradation of the
tumour suppressor p53 and its translation. Fahraeus and colleagues report
an additional layer of regulation: p53 mRNA binds directly to Mdm2 protein
to inhibit ubiquitin ligase activity, promoting its own translation.

Ripples from neighbouring transcription pp1106 - 1113
A new study shows that coordinated regulation of transcription due to a
transcriptional ripple effect is widespread in the mammalian genome.
Nishida and colleagues have found that induction of immediate early genes
is accompanied by upregulation of genes in the vicinity; this process is
dependent on the MAPK pathway and the transcription factor SRF.

Epigenetic transcriptional repression of cellular genes by a viral SET
protein pp1114 - 1122
Viruses use various mechanisms to hijack cellular processes. Zhou and

Nature Insight Inflammation

Inflammation is our body's immediate response to damage to its tissues and cells by pathogens or noxious stimuli such as chemicals or physical injury. While initiation and the process of acute inflammation are reasonably well defined, much less is known about the causes and pathways associated with chronic inflammation. This Insight highlights recent advances in our knowledge of the exogenous and endogenous inducers of chronic inflammation, the inflammatory mediators and the cells that carry out the response.

Read the Insight in the 24th July issue of Nature or access it online.

High-throughput, quantitative analyses of genetic interactions in
E. coli pp781 - 787
An array-based high-throughput approach, genetic interaction analysis

comprehensive genetic interaction screens in bacteria. The method
uses bacterial conjugation and robotic technology to generate double
mutants on a genome-wide scale. In this issue another paper presents
eSGA, a very similar approach.

Single-spike detection in vitro and in vivo with a genetic Ca2+
sensor pp797 - 804
Measurement of in vivo neuronal activity with single neuron and
single action potential resolution is important for studying neuronal
function. Delivery of a FRET-based fluorescent Ca2+ indicator protein
using adeno-associated virus results in high expression levels
allowing in vivo detection of single action potentials at low firing
rates. Griesbeck et al., also online, describe the use of a similar
sensor for recording neuronal activity in vivo.

A genetically encoded calcium indicator for chronic in vivo
two-photon imaging pp805 - 811
To study long-term changes in neuronal circuits at single-cell
resolution, a Troponin C-based Ca2+ indicator protein has been
reengineered to increase the signal strength. This allows repeated
measurements, over days and weeks, of orientation selective neurons
in mouse visual cortex. Hasan et al., also in this issue, describe
the use of a similar sensor for recording neuronal activity in vivo.

mirWIP: microRNA target prediction based on microRNA-containing
ribonucleoprotein-enriched transcripts pp813 - 819
A new prediction algorithm for microRNA targets, mirWIP, is

dataset and identifies verified miRNA-mRNA interactions in
Caenorhabditis elegans with improved specificity compared to current
methods.

Holographic photolysis of caged neurotransmitters pp821 - 827
Holographic illumination allows the production of complex,
user-defined, two-dimensional illumination patterns. Used to
manipulate light-sensitive molecules in cells, this system permits
their simultaneous excitation at multiple locations of arbitrary
shape and size-facilitating spatial and temporal regulation
of cell function.
