Dopamine D4receptors (D4Rs) are G protein-coupled receptors that play a
role in attention and cognition. In the present study, we investigated the
dimerization properties of this receptor. Western blot analysis of the
human D4.2R, D4.4R and D4.7R revealed the presence of higher molecular
weight immunoreactive bands, which might indicate the formation of
receptor dimers and multimers.

The cytochromecd1nitrite reductase fromParacoccus pantotrophuscatalyses
the one electron reduction of nitrite to nitric oxide using two heme cofactors.
The site of nitrite reduction is thed1
heme, which is synthesized under anaer-obic conditions by usingnirECFD-LGHJNgene products.
Mitochondrial biogenesis, which depends on nuclear as well as mitochon-drial genes, occurs in response to increased cellular ATP demand. The
nuclear transcriptional factors, estrogen-related receptor a (ERRa) and
nuclear respiratory factors 1 and 2, are associated with the coordination of
the transcriptional machinery governing mitochondrial biogenesis
c-Type cytochromes require specific post-translational protein systems,
which vary in different organisms, for the characteristic covalent attach-ment of heme to the cytochrome polypeptide. Cytochromec biogenesis
System II, found in chloroplasts and many bacteria, comprises four subun-its, two of which (ResB and ResC) are the minimal functional unit.
Mitochondrial cytochromescandc1 are present in all eukaryotes that use
oxygen as the terminal electron acceptor in the respiratory chain. Matura-tion of c-type cytochromes requires covalent attachment of the heme cofac-tor to the protein, and there are at least five distinct biogenesis systems
that catalyze this post-translational modification in different organisms and
We have developed a simple reporter assay useful for detection and analysis
of mutations and agents influencing mRNA biogenesis in a gene length-dependent manner. We have shown that two transcription units sharing the
same promoter, terminator and open reading frame, but differing in the
length of their 3¢-untranslated regions, are differentially influenced by muta-

Deficient mitochondrial biogenesis in critical illness: cause, effect, or epiphenomenon?
Many recent studies have reported that microRNA (miRNA) biogenesis
and function are related to the molecular mechanisms of various clinical
diseases. Several methods, including northern blotting and DNA chip anal-yses, are capable of assessing miRNA-production patterns in cells. How-ever, the development of repetitive monitoring of the miRNA-production
profile in a noninvasive manner is demanded for the application of
miRNAs to human medicine.
Genetic and proteomic approaches have led to the identification of 32 pro-teins, collectively called peroxins, which are required for the biogenesis of
peroxisomes. Some are responsible for the division and inheritance of per-oxisomes; however, most peroxins have been implicated in the topogenesis
of peroxisomal proteins. Peroxisomal membrane and matrix proteins are
synthesized on free ribosomes in the cytosol and are imported post-trans-lationally into pre-existing organelles (Lazarow PB & Fujiki Y (1985) Annu
Rev Cell Biol1, 489–530 )....
Alterations in mitochondrial activity resulting from defects in mitochond-rial DNA (mtDNA) can modulate the biogenesis of mitochondria by mech-anisms that are still poorly understood. In order to study mitochondrial
biogenesis in cells with impaired mitochondrial activity, we used rho-L929
143 B cells (partially and totally depleted of mtDNA, respectively),
Mitochondrial uncoupling protein 1 (UCP1) is a speci®c
marker of multilocular brown adipocytes. Ectopic UCP1 in
white fat of aP2-Ucp1micemitigates development of obesity
byboth, increasing energy expenditure anddecreasingin situ
lipogenesis. In order to further analyse consequences of
respiratory uncoupling inwhite fat, the eects of the ectopic
UCP1 on the morphology of adipocytes and biogenesis of
mitochondria in these cells were studied.

carriers have different shapes and sizes, and their biogenesis, modality of transport,
and delivery to the final destination are regulated by a multitude of very complex
molecular machineries, which include cytoskeletal elements, signaling complexes, and
lipid modifying enzymes to name a few. A concept that has clearly emerged in the last
decade is that each membrane pathway does not represent a close system, but is fully
integrated with all the other trafficking pathways.

PLANT CELLS, UNLIKE ANIMAL CELLS, are surrounded by a relatively thin but mechanically strong cell wall. This wall consists of a complex mixture of polysaccharides and other polymers that are secreted by the cell and are assembled into an organized network linked together by both covalent and noncovalent bonds. Plant cell walls also contain structural proteins, enzymes, phenolic polymers, and other materials that modify the wall’s physical and chemical characteristics.
