On the sequencing of
the human genome
|
|
Our analysis indicates that the Celera paper provides
neither a meaningful test of the WGS approach nor an independent
sequence of the human genome. Our analysis does not imply that
a WGS approach could not be successfully applied to assemble
a draft sequence of a large mammalian genome, but merely that
the Celera paper does not provide such evidence.

Splenic immunity and
atherosclerosis:a glimpse into a novel paradigm?
|
|
In particular, there is now strong and growing evidence
in hypercholesterolemic animal models that the immune system
is specifically activated by atherosclerosis-associated antigens
and that both innate and adaptive immunity can significantly
modulate subsequent lesion development.

Prospects for Anti-RAS
Drugs
|
|
Remarkable progress in understanding the mechanisms
of Ras regulation and signal transduction has provided additional
targets for rational drug design approaches to block or possibly
to revert the aberrant function of Ras signalling in human cancer.

Acupuncture: Theory,
Efficacy, and Practice
|
|
Recent data, obtained by using functional magnetic
resonance imaging, suggest that acupuncture has regionally specific,
quantifiable effects on relevant brain structures. Acupuncture
may stimulate gene expression of neuropeptides. The training
and provision of acupuncture care in the United States are rapidly
expanding.

RHO–GTPases and Cancer
|
|
A branch of the RAS family — the RHO proteins —
is also involved in cancer, but what is the role of these proteins
and would they make good therapeutic targets?

Molecular ticket to
enter cells
|
|
Just as important as starting cellular signalling
pathways is switching them off again. It seems that the Cbl
protein has a dual function in accelerating the degradation
of certain signalling molecules.

Toll-like Receptors
|
|
The Toll-like receptors(TLRs) are a part of this
innate immune defense, recognizing conserved patterns on microorganisms.And
TLR signaling represents a key component of the innate immune
response to microbial infection.

The IKK/NF-κB pathway
|
|
There are several well-characterized signaling pathways
and transcription factors that are likely to be involved in
critical diseases. Of these, the IKK/NF-κB pathway might play
an exceptionally important role because of the rapidity of activation
and its unique regulation.

Signaling by protein
phosphatases in the nucleus
|
|
Here,we review the pleiotropic action of nuclear
protein phosphatases and focus in particular on the underlying
signaling strategies. It appears that nuclear protein phosphatases
can both mediate and antagonize signaling by protein kinases,
sometimes as part of feedback loops.

Degeneracy, as opposed
to specificity,in immunotherapy Commentary
|
|
As has only recently been appreciated, while a given
T cell receptor may ordinarily exhibit exquisite specificity,
binding to some antigenic sequences can effect a conformational
change to the receptor,allowing it to recognize MHC class II/peptide
complexes in a highly degenerate fashion.

The Golgi apparatus:
going round in circles?
|
|
It is proposed that Golgi apparatus proteins continuously
recycle via the endoplasmic reticulum by vesicle transport,
whereas cargo molecules remain in maturing cisternal structures.

Unlocking the Gates
to Gene Expression
|
|
It is now clear that activators must orchestrate
the recruitment of numerous proteins including chromatin-remodeling
enzymes before gene transcription can proceed.

Two-hybrid arrays
|
|
The two-hybrid assay can be applied to random libraries
or arrays of colonies that express defined pairs of proteins.
Arrays enable the testing of all possible protein pairs for
interactions in a systematic fashion.

Applied Proteomics:Mitochondrial
Proteins and Effect on Function
|
|
The identification of a majority of the polypeptides
in mitochondria would be invaluable because they play crucial
and diverse roles in many cellular processes and diseases.The
rapidly emerging field of proteomics can provide powerful strategies
for the characterization of mitochondrial proteins.

Mechanisms of ageing:Public
or Private?
|
|
Evidence is mounting that modulators of the rate
of ageing are conserved over large evolutionary distances. As
we discuss in this review, this conservation might stem from
mechanisms that match reproductive rate to nutrient supply.

Genome complexity
reduction for SNP genotyping analysis
|
|
An efficient method that can be used to simultaneously
amplify a set of genetic loci across a genome with high reliability
can provide a valuable tool for large-scale SNP genotyping studies.
In this paper we describe and characterize a method that addresses
this goal.

Functional protein
microarrays
|
|
Micro-immunoassays, in which biological samples
are exposed to arrays of immobilized antibodies, can be used
for protein expression profiling. In addition, protein function
can be elucidated by performing binding and enzymatic assays
on arrays of biologically active proteins.

Angiotensin, Inflammation,Hypertension,
and Cardiovascular Disease

Recent evidence shows that Ang II is important in
stimulating the production of reactive oxygen species and the
activation of ancient inflammatory mechanisms. The nuclear factor
kB (NF-kB) is pivotal to these processes.

Functional diversity
of protein C-termini: more than zipcoding?
|
|
The combination of diversity and the plasticity
of the chemistry of C-termini provides mechanisms for spatial
and temporal specificity that are exploited by a variety of
biological processes, ranging from specifying prokaryotic protein
degradation to nucleating mammalian neuronal signaling complexes.

Angiotensin II induced
inflammation in the kidney and in the heart of double transgenic
rats
|
|
Our data show that inhibition of NF-κB by PDTC markedly
reduces inflammation, iNOS expression in the dTGR most likely
leading to decreased cytotoxicity, and cell proliferation. Thus,
NF-κB activation plays an important role in ANG II-induced end-organ
damage.

Advanced Glycation End

|
Recent studies suggested that AGEs may form in inflamed
foci, driven by oxidation or the myeloperoxidase pathway.We
tested the hypothesis that interaction of AGEs with RAGE on
endothelial cells enhances vascular activation.

review describes insights from engineering theory and practice
that can shed some light on biological complexity.

Systems Biology: A Brief
Overview

function, rather than the characteristics of isolated parts
of a cell or organism.
