mRNA levels for α-subunit of prolyl 4-hydroxylase and fibrillar collagens in immobilized rat skeletal muscle

1999

There is evidence that immobilization causes a decrease in total collagen synthesis in skeletal muscle within a few days. In this study, early immobilization effects on the expression of prolyl 4-hydroxylase (PH) and the main fibrillar collagens at mRNA and protein levels were investigated in rat skeletal muscle. The right hindlimb was immobilized in full plantar flexion for 1, 3, and 7 days. Steady-state mRNAs for α- and β-subunits of PH and type I and III procollagen, PH activity, and collagen content were measured in gastrocnemius and plantaris muscles. Type I and III procollagen mRNAs were also measured in soleus and tibialis anterior muscles. The mRNA level for the PH α-subunit decreas…

Isolation and characterization of cold-shock domain protein genes, Oryzias latipes Y-box protein 2 ( OlaYP2 ) and Fugu rubripes Y-box protein 1 ( Fru…

2002

The Y-box protein (YP) family shares a nucleic acid binding domain, called cold-shock domain, that has been evolutionarily highly conserved from bacteria to human. The different YPs identified so far in vertebrates are thought to function as transcriptional activators, transcriptional repressors and/or translational repressors. Medakafish and pufferfish are very suitable vertebrate models for the study of developmental genetics and comparative genomics, respectively. Here we report the isolation of two teleost YP genes, medakafish Oryzias latipes (Ola)YP2 and Fugu rubripes (Fru)YP1, which are expressed in multiple tissues. Phylogenetic analysis demonstrated that OlaYP2 and FruYP1 belong to …

Differential regulation by a peroxisome proliferator of the different multifunctional proteins in guinea pig: cDNA cloning of the guinea pig D-specif…

1998

After our previous report on the cloning of two cDNA species in guinea pig, both encoding the same hepatic 79 kDa multifunctional protein 1 (MFP-1) [Caira, Cherkaoui-Malki, Hoefler and Latruffe (1996) FEBS Lett. 378, 57-60], here we report the cloning of a cDNA encoding a second multifunctional peroxisomal protein (MFP-2) in guinea-pig liver. This 2356 nt cDNA encodes a protein of 735 residues (79.7 kDa) whose sequence shows 83% identity with rat MFP-2 [Dieuaide-Noubhani, Novikov, Baumgart, Vanhooren, Fransen, Goethals, Vandekerckhove, Van Veldhoven and Mannaerts (1996) Eur. J. Biochem. 240, 660-666]. In parallel, we studied the effect of ciprofibrate, a hypolipaemic agent also known as per…

Induction of Cerebral Ischemic Tolerance by Erythromycin Preconditioning Reprograms the Transcriptional Response to Ischemia and Suppresses Inflammat…

2007

Background A single dose of the macrolide antibiotic erythromycin can induce tolerance against cerebral ischemia in vivo (pharmacologic preconditioning). This study identified potential mechanisms of tolerance induction by assessing effects of erythromycin preconditioning on the cerebral transcriptional response to transient global cerebral ischemia. Methods Preconditioned and nonpreconditioned rats were exposed to 15 min of global cerebral ischemia, and changes in cerebral gene expression were identified by complementary DNA expression array and quantified by real-time reverse-transcription polymerase chain reaction. Results Ischemia caused a widespread up-regulation of transcription in n…

The new gene DmX from Drosophila melanogaster encodes a novel WD-repeat protein

1998

DmX is a novel gene from Drosophila melanogaster located on the X chromosome in region 5D5/6-E1. The molecular analysis of the genomic and cDNA sequences of DmX shows that the gene spans appr. 16kb and displays a mosaic structure with 15 exons. The 12kb long DmX transcript is present in Drosophila embryos, larvae and adults of both sexes. The open reading frame of DmX encodes a novel WD-repeat protein, containing at least 30 WD-repeat units. WD-repeat proteins contain a conserved motif of approximately 40 amino acids (aa), usually ending with the dipeptide Trp-Asp (WD). Homologues of the DmX gene exist in other dipteran species, in Caenorhabditis elegans and human, revealing that DmX is an …

Mutations in a new gene, encoding a zinc-finger protein, cause tricho-rhino-phalangeal syndrome type I

1999

Tricho-rhino-phalangeal syndrome type I (TRPS I, MIM 190350) is a malformation syndrome characterized by craniofacial and skeletal abnormalities and is inherited in an autosomal dominant manner. TRPS I patients have sparse scalp hair, a bulbous tip of the nose, a long flat philtrum, a thin upper vermilion border and protruding ears. Skeletal abnormalities include cone-shaped epiphyses at the phalanges, hip malformations and short stature. We assigned TRPS1 to human chromosome 8q24. It maps proximal of EXT1, which is affected in a subgroup of patients with multiple cartilaginous exostoses and deleted in all patients with TRPS type II (TRPS II, or Langer-Giedion syndrome, MIM 150230; ref.2-5)…

Molecular cloning and characterization of the cDNA encoding the rat liver gamma-butyrobetaine hydroxylase

1999

Carnitine biosynthesis from lysine and methionine involves five enzymatic reactions. gamma-butyrobetaine hydroxylase (BBH; EC 1.14. 11.1) is the last enzyme of this pathway. It catalyzes the reaction of hydroxylation of gamma-butyrobetaine to carnitine. The cDNA encoding this enzyme has been isolated and characterized. The cDNA contained an open reading frame of 1161 bp encoding a protein of 387 amino acids with a deduced molecular weight of 44.5 kDa. The sequence of the cDNA showed an important homology with the human cDNA recently isolated. Northern analysis showed gamma-butyrobetaine hydroxylase expression in the liver and in some extend in the testis and the epididymis. During this stud…

Quantitation of GABA transporter 3 (GAT3) mRNA in rat brain by competitive RT-PCR.

1999

Gamma-amino butyric acid is the major inhibitory neurotransmitter in the brain. GABA transporters (GATs) remove GABA from the synaptic cleft. Till now, five distinct GABA transporters have been cloned and termed consecutively GAT1 to GAT4 and vGAT. To study the mechanisms by which tolerance and dependence associated with drugs enhancing GABAergic transmission is brought upon we analysed the mRNA expression levels of GATs in various brain regions under different conditions. In this paper, we describe our protocol for measurement of GAT3 mRNA expression, and its validation through control experiments for the various steps. We performed competitive reverse transcription and polymerase chain re…

Caries treatment in a four-year-old boy using hypnosis - a case report.

2021

This clinical case report demonstrates the successful application of hypnosis in an anxious four-year-old boy in whom two primary molars were treated with a composite filling. The almost 16-minute pediatric dental treatment was performed without complications and without interruptions. It could be shown that hypnosis can be used for the pediatric dental treatment of decayed primary tooth lesions. In the specific individual case hypnosis was not only used adjuvant but as an alternative to local anesthesia. A dental anxiety reducing effect and an elimination of pain perception were observed, so that the treatment was possible without anesthesia. It was also found that the communication and ra…
