The intracellular transfer of information (biological activation/inhibition) through a signal pathway. In each signal transduction system, an activation/inhibition signal from a biologically active molecule (hormone, neurotransmitter) is mediated via the coupling of a receptor/enzyme to a second messenger system or to an ion channel. Signal transduction plays an important role in activating cellular functions, cell differentiation, and cell proliferation. Examples of signal transduction systems are the GAMMA-AMINOBUTYRIC ACID-postsynaptic receptor-calcium ion channel system, the receptor-mediated T-cell activation pathway, and the receptor-mediated activation of phospholipases. Those coupled to membrane depolarization or intracellular release of calcium include the receptor-mediated activation of cytotoxic functions in granulocytes and the synaptic potentiation of protein kinase activation. Some signal transduction pathways may be part of larger signal transduction pathways; for example, protein kinase activation is part of the platelet activation signal pathway.

Features of the immune response to DNA in mice. I. Genetic control. (1/5588)

The genetic control of the immune response to DNA was studied in various strains of mice F1 hybrids and corresponding back-crosses immunized with single stranded DNA complexed to methylated bovine serum albumin. Anti-DNA antibody response was measured by radioimmuno-logical technique. High responder, low responder, and intermediate responder strains were found and the ability to respond to DNA was characterized as a dominant genetic trait which is not linked to the major locus of histocompatibility. Studies in back-crosses suggested that this immune response is under multigenic control. High responder mice produce both anti-double stranded DNA and anti-single stranded DNA 7S and 19S antibodies, while low responder mice produce mainly anti-single stranded DNA 19S antibodies.  (+info)

Assaying potential carcinogens with Drosophila. (2/5588)

Drosophila offers many advantages for the detection of mutagenic activity of carcinogenic agents. It provides the quickest assay system for detecting mutations in animals today. Its generation time is short, and Drosophila is cheap and easy to breed in large numbers. The simple genetic testing methods give unequivocal answers about the whole spectrum of relevant genetic damage. A comparison of the detection capacity of assays sampling different kinds of genetic damage revealed that various substances are highly effective in inducing mutations but do not produce chromosome breakage effects at all, or only at much higher concentrations than those required for mutation induction. Of the different assay systems available, the classical sex-linked recessive lethal test deserves priority, in view of its superior capacity to detect mutagens. Of practical importance is also its high sensitivity, because a large number of loci in one fifth of the genome is tested for newly induced forward mutations, including small deletions. The recent findings that Drosophila is capable of carrying out the same metabolic activation reactions as the mammalian liver makes the organism eminently suitable for verifying results obtained in prescreening with fast microbial assay systems. An additional advantage in this respect is the capacity of Drosophila for detecting short-lived activation products, because intracellular metabolic activation appears to occur within the spermatids and spermatocytes.  (+info)

KCNQ4, a novel potassium channel expressed in sensory outer hair cells, is mutated in dominant deafness. (4/5588)

Potassium channels regulate electrical signaling and the ionic composition of biological fluids. Mutations in the three known genes of the KCNQ branch of the K+ channel gene family underlie inherited cardiac arrhythmias (in some cases associated with deafness) and neonatal epilepsy. We have now cloned KCNQ4, a novel member of this branch. It maps to the DFNA2 locus for a form of nonsyndromic dominant deafness. In the cochlea, it is expressed in sensory outer hair cells. A mutation in this gene in a DFNA2 pedigree changes a residue in the KCNQ4 pore region. It abolishes the potassium currents of wild-type KCNQ4 on which it exerts a strong dominant-negative effect. Whereas mutations in KCNQ1 cause deafness by affecting endolymph secretion, the mechanism leading to KCNQ4-related hearing loss is intrinsic to outer hair cells.  (+info)

Familial antiphospholipid antibody syndrome: criteria for disease and evidence for autosomal dominant inheritance. (5/5588)

OBJECTIVE: To develop diagnostic criteria for a familial form of antiphospholipid antibody syndrome (APS), identify families with >1 affected member, examine possible modes of inheritance, and determine linkage to potential candidate genes. METHODS: Family members of probands with primary APS were analyzed for clinical and laboratory abnormalities associated with APS. Families with > or =2 affected members were analyzed by segregation analysis and typed for candidate genetic markers. RESULTS: Seven families were identified. Thirty of 101 family members met diagnostic criteria for APS. Segregation studies rejected both environmental and autosomal recessive models, and the data were best fit by either a dominant or codominant model. Linkage analysis showed independent segregation of APS and several candidate genes. CONCLUSION: Clinical and laboratory criteria are essential to identify the spectrum of disease associated with APS. We believe a set of criteria was developed that can precisely define affected family members with APS. Modeling studies utilizing these criteria strongly support a genetic basis for disease in families with APS and suggest that a susceptibility gene is inherited in an autosomal dominant pattern. However, in these families, APS was not linked with HLA, Fas, or other candidate genes, including beta2-glycoprotein 1, HLA, T cell receptor beta chain, Ig heavy chain, antithrombin III, Fas ligand, factor V, complement factor H, IgK, and Fas.  (+info)

Expression of dominant negative Erk2 inhibits AP-1 transactivation and neoplastic transformation. (6/5588)

The mitogen activated protein (MAP) kinases or extracellular signal-regulated kinases (Erks) are activated in response to Ras expression or exposure to tumor promoters or to growth factors, and have been implicated in AP-1 transactivation in some models. We have shown that tumor promoter induced activation of the transcription factor AP-1 is required for induced neoplastic transformation in the Balb/C JB6 cell model. Jun and Fos family protein levels have been found not to be limiting for AP-1 response. The present study asks whether activation of Erks1 and 2 is required for AP-1 transactivation and transformation of JB6 cells and whether Erks might be targeted for cancer prevention. Expression of either of two different dominant negative kinase inactive Erk2 mutants in transformation sensitive (P+) JB6 cells substantially inhibited the tumor promoter induced activation of Erks1 and 2 and of AP-1 measured by a collagenase-luciferase reporter. Multiple mutant Erk2 expressing clonal lines were also rendered non-responsive to induced neoplastic transformation. These observations, together with our recent finding attributing AP-1 non-responsiveness to Erk deficiency in a clonal line of transformation resistant (P-) cells, argue for a requirement for Erks1 and/or 2 activation in AP-1 transactivation in the mouse JB6 neoplastic progression model, and suggest the utility of Erks as a prevention target.  (+info)

Familial essential ("benign") chorea. (7/5588)

A family is described with essential non-progressive chorea occurring in an autosomal dominant inheritance pattern over four generations. A few families with an apparently similar disorder have been reported previously. This condition is characterized by early childhood onset of chorea which is not progressive and is compatible with a long life. It is not associated with dementia, seizures, rigidity, or ataxia. It is a socially embarrassing condition and may, sometimes, be associated with behavioural problems and learning difficulties. For genetic counselling, it is important to distinguish this disorder from Huntington's disease and other hereditary disorders associated with chorea.  (+info)

Family study of inherited syndrome with multiple congenital deformities: symphalangism, carpal and tarsal fusion, brachydactyly, craniosynostosis, strabismus, hip osteochondritis. (8/5588)

A syndrome of brachydactyly (absence of some middle or distal phalanges), aplastic or hypoplastic nails, symphalangism (ankylois of proximal interphalangeal joints), synostosis of some carpal and tarsal bones, craniosynostosis, and dysplastic hip joints is reported in five members of an Italian family. It may represent a previously undescribed autosomal dominant trait.  (+info)

Autosomal dominant inheritance is due to a dominant allele carried on one of the autosomes. Autosomal dominant alleles need only be inherited from one parent, either the mother or the father, in order to be expressed in the phenotype. Because of this, any child has a 50 percent chance of inheriting the allele and expressing the trait if one parent has it.. Many normal human traits are due to autosomal dominant alleles, including the presence of dimples, a cleft chin, and a widows-peak hairline. Note that dominant does not necessarily mean common. Dominant alleles can be rare in a population, and do not spread simply because they are dominant. This phenomenon is explained by the theory known as Hardy-Weinberg equilibrium.. There are hundreds of medical conditions due to autosomal dominant alleles, most of them very rare. They include neurodegenerative disorders such as Huntingtons disease, a variety of deafness syndromes, and metabolic disorders such as familial hypercholesterolemia (affecting ...
A family extending over 4 generations showed iridogoniodysgenesis accompanied by somatic malformations inherited in an autosomal dominant fashion. Iridogoniodysgenesis was present in 10 members, of whom 5 had established glaucoma; 4 youthful members are likely to develop glaucoma. Somatic malformations were present in 5 members from the 3rd and 4th generations who did not manifest iridogoniodysgenesis. A possible polygenic basis is discussed, though the variable expression of an autosomal dominant inheritance is still the more likely explanation. ...

Lithuim: Dominant traits arent preferentially passed along between generations, they just express more strongly if they are passed down.. If a dominant gene is rare, it may continue to be rare unless theres some selective pressure killing off animals without it.. whythecynic: Dominant and recessive simply describe how two *alleles* interact with each other. A dominant allele may be *disadvantageous*- in which case it would slowly die out. It might simply be rarer- when most of the population has recessive alleles, the dominant allele doesnt increase in number as quickly.. Thats the simple description- lets look at it closely!. ## Alleles. The DNA of humans (like most animals) is paired up. We have two copies of each gene. Each copy doesnt have to be the same, too, and we can have two different versions of the same gene.. Each version of a gene is called an *allele*.. ## Dominance. When an allele is *dominant*, the organism takes on that trait even if it has another *recessive* allele. ...

A gene on one of the first 22 pairs of chromosomes, which, when present in one copy, causes a trait or disease to be expressed. Autosomal dominant inheritance means that the gene carrying a mutation is located on one of the autosomes (chromosome pairs 1 through 22). This means that males and females are equally likely to inherit the mutation. Dominant means that having a mutation in just one of the two copies of a particular gene is all it takes for a person to have a trait, such as an increased risk of developing cancer (see explanation below on variable expressivity and reduced penetrance). When a parent has a dominant gene mutation, there is a 50 percent chance that any child he/she has will also inherit the mutation. There are four possible combinations in the children. Two of the four, or 50 percent, have inherited the mutation. The other 50 percent have not inherited the mutation. These four combinations are possible every time a pregnancy occurs between these two individuals. The ...
These studies show that DN-TNF biologics selectively inhibit solTNF activity in vitro and in vivo. DN-TNFs blocked paracrine (solTNF) signaling in human and mouse cell lines and in a human whole blood cytokine release assay and were as effective as a nonselective decoy receptor in reducing inflammation in two mouse models of arthritis. In contrast, DN-TNFs failed to block juxtacrine signaling induced by human or mouse tmTNF in the same assays. DN-TNF biologics also maintained innate resistance to L. monocytogenes infection in normal and tmTNF knockin mice, while nonselective TNF inhibition by decoy receptor led to a marked immunosuppression and increased mortality.. SolTNF selectivity appears to be an intrinsic property of the dominant-negative mechanism of DN-TNFs. Although the molecular basis for solTNF ligand selectivity remains to be explored, one explanation is that solTNF homotrimers are more labile than tmTNF homotrimers. Trimer dissociation is obligatory for exchange and is likely to be ...

A significant but unquantified portion of genetic diseases is non-inherited; occurring from de novo (new) mutations in the the germ cells of the affected individuals. In humans, point mutations (i.e., mutations that occur in a single nucleotide base within the genome) occur with a frequency of about 1 to 3 x 10-8 per base (1), (2). There are many types of mutational alterations other than point mutations (e.g., mutations in microsatellites) (3). Our knowledge of the likelihood of other types of mutation most of these alternate types of mutation is limited. In many cases de novo mutations cause lethal genetic diseases that occur in children, through the action of a dominant gene (i.e., one gene copy that produces the disease). Such diseases are seldom inherited because they cannot be conserved in the population; those with the gene die early in life, without passing the gene to progeny. Sometimes, non-inheritance accounts for some proportion of cases that would otherwise occur as dominant gene ...
If two unrelated resistant plants are crossed (PAM), you may be dealing with the same type of gene(s) or you may be combining different types of genes. If one of those genes is dominant from either parent, then you can expect (in theory) as many as 50% (somewhat) resistant offspring from such a mating if the parent with the dominant gene is heterozygous for the gene and as many as (in theory) 100% showing some resistance (not immunity!!) if the parent with the dominant gene is homozygous for the gene, though in practice we rarely see such high numbers, or at least do not recognize them as the resistance levels of heterozygotes can be variable. If both plants are carrying multiple genes, then the outcomes can be very variable (this might be termed quantitative expression), but as long as some of the recessives are compatible genes, you should see some resistant offspring. It is likely you will see a few offspring as or more resistant than the parents, but not always (as mentioned above, you ...

Here we report recruitment of a three-generation Romani (Gypsy) family with autosomal dominant cone-rod dystrophy (adCORD). Involvement of known adCORD genes was excluded by microsatellite (STR) genotyping and linkage analysis. Subsequently, two independent total-genome scans using STR markers and single-nucleotide polymorphisms (SNPs) were performed. Haplotype analysis revealed a single 6.7-Mb novel locus between markers D10S1757 and D10S1782 linked to the disease phenotype on chromosome 10q26. Linkage analysis gave a maximum LOD score of 3.31 for five fully informative STR markers within the linked interval corresponding to the expected maximum in the family. Multipoint linkage analysis of SNP genotypes yielded a maximum parametric linkage score of 2.71 with markers located in the same chromosomal interval. There is no previously mapped CORD locus in this interval, and therefore the data reported here is novel and likely to identify a new gene that may eventually contribute to new knowledge on ...
Researchers, based at the Department of Genetics, Instituto de Investigación Sanitaria-Fundación Jiménez Díaz University Hospital-Universidad Autónoma in Madrid, have published research on the spectrum of mutations and genes involved in autosomal dominant retinitis pigmentosa (adRP). The research was carried out on 258 unrelated Spanish families with a clinical diagnosis of RP and suspected autosomal dominant inheritance. The findings, published in the journal IOVS (doi.org/10.1167/iovs.18-23854), demonstrate the capability of defining 60% of genetic causes using a variety of classical and next generation diagnostics.. Historically, a broad number of clinical diagnoses of RP were genetically unknown, given limitations in technology and resources however, the Spanish study now indicates that with current tools, 60% of families were able to receive a genetic diagnosis. The landscape of the varying mutations and genes involved provide a valuable data set not only for the immediate families ...
Purpose.: Next-generation sequencing (NGS) has been demonstrated to be an effective strategy for the detection of mutations in retinal dystrophies, a group of inherited diseases that are highly heterogeneous. Therefore, the aim of this study is the application of an NGS-based approach in a Spanish cohort of autosomal dominant retinitis pigmentosa (RP) patients to find out causative mutations. Methods.: Index cases of 59 Spanish families with initial diagnosis of autosomal dominant RP and unsuccessfully studied for mutations in the most common RP causal genes, were selected for application of a NGS-based approach with a custom panel for 73 genes related to retinal dystrophies. Candidate variants were select based on frequency, pathogenicity, inherited model, and phenotype. Subsequently, confirmation by Sanger sequencing, cosegregation analysis, and population studies, was applied for determining the implication of those variants in the pathology. Results.: Overall 31 candidate variants were ...
Purpose : The P23H mutation in the rhodopsin (RHO) gene represents the most common form of autosomal dominant retinitis pigmentosa (adRP) in the US (~10%). We used a human P23H (hP23H) transgenic pig model of adRP to evaluate an allele-specific knock out strategy of the hP23H mutant sequence and determined if its inactivation (targeted gene knockout) could be a therapeutic intervention for adRP. Methods : A 930 nt I-CreI based homing endonuclease (HE) designed to knockout the hP23H RHO allele was packaged in a self-complementary AAV vector (scAAV). We evaluated the specificity of the HE for P23H RHO in a transgenic pig model expressing hP23H RHO (TgP23H RHO). scAAV-HE and scAAV-GFP (scAAV-HE/GFP) were coinjected subretinally (~40ul) into TgP23H RHO and wild-type (WT) littermates between postnatal days (P) 3 to 7. In ongoing experiments (50 eyes), we are screening a range of scAAV-HE/GFP titers, as well as controls at regular post injection intervals (≥14 weeks post injection (wpi)). Ocular ...
We have previously found linkage to chromosome 1p34 in five large families with autosomal dominant non-syndromic hearing impairment (DFNA2). In all five families, the connexin31 gene (GJB3), located at 1p34 and responsible for non-syndromic autosomal dominant hearing loss in two small Chinese families, has been excluded as the responsible gene. Recently, a fourth member of the KCNQ branch of the K+ channel family, KCNQ4, has been cloned. KCNQ4 was mapped to chromosome 1 p34 and a single mutation was found in three patients from a small French family with non-syndromic autosomal dominant hearing loss. In this study, we have analysed the KCNQ4 gene for mutations in our five DFNA2 families. Missense mutations altering conserved amino acids were found in three families and an inactivating deletion was present in a fourth family. No KCNQ4 mutation could be found in a single DFNA2 family of Indonesian origin. These results indicate that at least two and possibly three genes responsible for hearing ...

In the current study, we confirmed a missense mutation c. 139 G , A in Cx50 (GJA8) in a six-generation Chinese pedigree with congenital cataract. This mutation resulted in an asparagine substitution for aspartic at amino acid residue 47 (D47N).. Cataracts are defined as opacification of the normally transparent crystalline lens, and are the leading cause of vision loss in the world. Congenital cataract is a type of cataract that emerges at birth or during early childhood [5, 18]. The abnormality of lens can interfere with normal development of eyes [5, 19]. Congenital cataracts can be inherited or familial, either as an isolated lens phenotype or as part of a genetic/metabolic disorder, commonly with full penetrance and autosomal dominant transmission [19]. Genetic factors play an important role in congenital cataract [20]. Gene mutations that affecting the lens development during embryonic period are considered to be the main cause [18]. Up to now, more than 39 genes and loci have been ...
In this article, we will share on a rare form of congenital cataract known as cerulean cataract.. Cerulean cataract (also known as blue-dot cataract) occurs where there are blue-white opacities in the lens cortex (middle layer of the lens). It can develop during childhood or occur at birth (congenital). The cause of cerulean cataract is due to mutation of several genes. It is of autosomal dominant inheritance (i.e. an affected individual has a copy of the mutant gene and a normal gene on a pair of non-sex chromosomes). The cataract can develop in 1 or both eyes and is progressive. Visual acuity is well-preserved, and surgery is usually not required before adult life.. Infants with cerulean cataract may be asymptomatic depending on the severity of the opacities. If severe, complications such as nystagmus (rapid involuntary movement of the eyes) and amblyopia (lazy eye) can develop. Both male and female can be equally affected. Family history of congenital cataract is one of the risk ...

The INO2 gene of Saccharomyces cerevisiae is required for derepression of the phospholipid biosynthetic genes in response to inositol depletion. Conversely, the OPI1 gene is required for repression in response to inositol supplementation. Results of an in vitro assay have led to a model in which Opi1p interacts with Ino2p. However, there is no in vivo evidence to support this model. Additionally, most of the previously isolated ino2 mutants offer little insight into this model. Here, we report the isolation of a new class of dominant mutations in the INO2 gene, which yield constitutive expression of a target gene (i.e. an Opi(-) mutant phenotype). Two mutations reside in a region of the Ino2p required for interaction with Opi1p in vitro. Three other mutations are at the amino-terminus in a transcriptional activation domain.. ...
Inheriting a disease, condition, or trait depends on the type of chromosome affected (nonsex or sex chromosome). It also depends on whether the trait is dominant or recessive.. A single abnormal gene on one of the first 22 nonsex (autosomal) chromosomes from either parent can cause an autosomal disorder.. Dominant inheritance means an abnormal gene from one parent can cause disease. This happens even when the matching gene from the other parent is normal. The abnormal gene dominates.. This disease can also occur as a new condition in a child when neither parent has the abnormal gene.. A parent with an autosomal dominant condition has a 50% chance of having a child with the condition. This is true for each pregnancy.. It means that each childs risk for the disease does not depend on whether their sibling has the disease.. Children who do not inherit the abnormal gene will not develop or pass on the disease.. If someone is diagnosed with an autosomal dominant disease, their parents should also be ...
Blockade of mismatch repair in a plant can lead to hypermutation and a new genotype and/or phenotype. One approach used to generate hypermutable plants is through the expression of dominant negative alleles of mismatch repair genes in transgenic plants or derived cells. By introducing these genes into cells and transgenic plants, new cell lines and plant varieties with novel and useful properties can be prepared more efficiently than by relying on the natural rate of mutation. Moreover, methods to inhibit the expression and activity of endogenous plant MMR genes and their encoded products are also useful to generate hypermutable plants.
We have designed a system for targeted gene expression that allows the selective activation of any cloned gene in a wide variety of tissue- and cell-specific patterns. The gene encoding the yeast transcriptional activator GAL4 is inserted randomly into the Drosophila genome to drive GAL4 expression from one of a diverse array of genomic enhancers. It is then possible to introduce a gene containing GAL4 binding sites within its promoter, to activate it in those cells where GAL4 is expressed, and to observe the effect of this directed misexpression on development. We have used GAL4-directed transcription to expand the domain of embryonic expression of the homeobox protein even-skipped. We show that even-skipped represses wingless and transforms cells that would normally secrete naked cuticle into denticle secreting cells. The GAL4 system can thus be used to study regulatory interactions during embryonic development. In adults, targeted expression can be used to generate dominant phenotypes for use ...
Beta defects are typically autosomal recessive, but in a small percentage of cases the HBB mutation follows an autosomal dominant pattern of inheritance. In a recessive disorder, if one parent is a carrier, there is a 50% chance with each birth that the child will also be a carrier and a 0% chance that the child will inherit the disease. If both parents are carriers, there is a 25% chance with each birth that the child will inherit the disease and a 50% chance that each child will be a carrier. Carriers typically have no signs and symptoms but some may have a mild form of anemia. If the disease is autosomal dominant and one parent has the disorder, there is a 50% risk that their child will have the disorder.

Friedman developed an equation to predict the recurrence risk for an autosomal dominant condition when both parents are clinically unaffected.
Feline Hypertrophic Cardiomyopathy (HCM) is far and away the most common form of heart disease in the cat. Diagnosis of HCM means that there is a primary disease process causing the myocytes of the heart to behave inappropriately, and leads to enlargement of the heart, primarily of the left ventricle (the main muscular chamber that pumps blood to the body). Secondary hypertrophic diseases of the heart may be caused by hyperthyroidism or hypertension, and lead to signs that mimic HCM, but if addressed early may be reversible by treating the underlying condition. Primary HCM is not reversible, and has been shown to have a genetic link, particularly in Main Coons. Unfortunately, genotyping is not yet available. It is not yet possible to isolate the gene that causes HCM in cats, but through studying family trees, it has been shown to be an autosomal dominant gene in some Main Coons and likely other breeds as well. In cats, HCM presents with a high degree of phenotypic heterogeneity from patient to ...
Purpose Type 2 diabetes mellitus (type 2 DM) and maturity-onset diabetes of the young present some similar clinical and biochemical characteristics that make them difficult to differentiate. Currently, the polymorphism T130I (rs1800961) in the HNF4A (hepatocyte nuclear factor 4A) gene has been described as a risk factor to type 2 DM and shows an autosomal dominant inheritance pattern associated to β-cell function decrease. The aim of the present work was to characterize the phenotypic profile of the T130I carrier and noncarrier relatives included in 3 unrelated families. ...
There are many different conditions that involve the heart, and some are more likely to run in families than others. Inherited heart diseases are those that run in families and are caused by a mutation (or change) in one gene (or in a number of genes). There are many categories of inherited heart disease, including cardiomyopathies, arrhythmias, aneurysms/dissections, and familial hypercholesterolemia. See here for more information about each of these. Most of the inherited heart diseases are passed down in an autosomal dominant pattern and often show up in multiple generations in a family. ...

Sub-Aortic Stenosis, also known as sub-valvular aortic stenosis, is a polygenic dominant disease, although some of the data is equivocal regarding whether it is incomplete penetrance or modifying factors. Data on a study of Newfoundlands clearly showed that the disease was dominant, most probably polygenic, and uncertain what the other factors were.. Currently, research is being done on a significant incidence in Bouviers, where the pedigrees indicate that it is polygenic dominant.. The carrier modes, although somewhat similar between polygenic-dominant and recessive--in that a series of genes (multiple individual alleles in recessive, multiple single dominant loci in polygenic dominant) are required--is different in polygenic dominant inheritance in that one set of genes gets transmitted as carrier or affected genes, and the other may get transmitted as clear (whereas in recessive, both are carriers if bred to a clear, or are affected if bred to another affected or carrier).. In polygenic ...
The cyclin-dependent kinase member, Cdk5, is expressed in a variety of cell types, but neuron-specific expression of its activator, p35, is thought to limit its activity to neurons. Here we demonstrate that both Cdk5 and p35 are expressed in the human astrocytoma cell line, U373. Cdk5 and p35 are present in the detergent-insoluble cytoskeletal fraction of this cell line and Cdk5 localizes to filopodia and vinculin-rich regions of cell-matrix contact in lamellopodia. When exposed to a 46(o)C heat shock, U373 cells change shape, lose cell-matrix contacts and show increased levels of apoptosis. To test whether Cdk5 activation might play a role in these events, U373 cells were stably transfected with histidine-tagged or green fluorescent protein-tagged constructs of Cdk5 or a dominant negative mutation, Cdk5T33. Under normal growth conditions, growth characteristics of the stably transfected lines were indistinguishable from untransfected U373 cells and Cdk5 localization was not changed. However, ...

One problem with the strategy of using dominant-negative mutations is the potential for influencing other, unrelated regulatory proteins. Although RSG does not interact with those known plant bZIP proteins that we have tested, we cannot completely rule out the possibility that the morphological changes of 35S:RSGbZIP-transformed plants could reflect the cross-inhibition of other transcriptional factors. Identifying the target gene of RSG would provide the most direct evidence that RSG regulates the endogenous amount of GAs. Our results using the dominant-negative form of RSG suggest that RSG might regulate one of the genes that encode enzymes for biosynthesis of GA. Substantial progress has been made in isolating the genes encoding the enzymes of the GA biosynthetic pathway (Hedden and Kamiya, 1997). We found GA18 to be effective in promoting cell elongation in 35S:RSGbZIP plants (data not shown). GA18 is not biologically active by itself but becomes active by sequential conversion to GA1 by a ...
