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…

Heterogeneity in the genetic basis of human complement C9 deficiency

Genetic control of C3 production by the S region of the mouse MHC.

1988

SUMMARY The present paper reports evidence indicating that the level of the third complement component (C3) is regulated by the S region of the murine H-2 complex. In fact, using congenic strains of mice we demonstrate that mice with the k haplotype at the S region show high C3 levels, whereas mice with the d haplotype at the S region show low C3 levels.

Multiple identification of a particular type of hereditary C1q deficiency in the Turkish population: review of the cases and additional genetic and f…

1997

Complete selective deficiencies of the complement component C1q are rare genetic disorders that are associated with recurrent infections and a high prevalence of lupus erythematosus-like symptoms. All C1q deficiencies studied at the genetic level revealed single-base mutations leading to termination codons, frameshifts or amino acid exchanges and these were thought to be responsible for the defects as no other aberrations were found. One particular mutation, leading to a stop codon in the C1qA gene, was first identified in members of a Gypsy family from the Slovak Republic. The same mutation has been found in all cases of C1q deficiency from Turkey that have been investigated. Here we prese…

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…

Complement C1q is dramatically up-regulated in brain microglia in response to transient global cerebral ischemia.

2000

Abstract Recent evidence suggests that the pathophysiology of neurodegenerative and inflammatory neurological diseases has a neuroimmunological component involving complement, an innate humoral immune defense system. The present study demonstrates the effects of experimentally induced global ischemia on the biosynthesis of C1q, the recognition subcomponent of the classical complement activation pathway, in the CNS. Using semiquantitative in situ hybridization, immunohistochemistry, and confocal laser scanning microscopy, a dramatic and widespread increase of C1q biosynthesis in rat brain microglia (but not in astrocytes or neurons) within 24 h after the ischemic insult was observed. A marke…

Differential expression of the murine mannose-binding lectins A and C in lymphoid and nonlymphoid organs and tissues.

2003

Abstract Mannose-binding lectin (MBL), a member of the collectin family, binds to carbohydrate structures on the surfaces of micro-organisms and may serve as a recognition molecule of the lectin pathway of complement activation. In rodents two forms, MBL-A and MBL-C, were described and shown to be products of two related, but uncoupled, genes. The liver is the main source of MBL biosynthesis. For rat MBL-A, expression has also been described in the kidney. Here we report that the two forms of murine MBL are differentially expressed in a number of nonhepatic tissues. Real-time RT-PCR revealed that the liver is the major site of expression for both MBL genes. Lower copy numbers were found in …

The Genome of the Sea Urchin Strongylocentrotus purpuratus

2006

We report the sequence and analysis of the 814-megabase genome of the sea urchin Strongylocentrotus purpuratus , a model for developmental and systems biology. The sequencing strategy combined whole-genome shotgun and bacterial artificial chromosome (BAC) sequences. This use of BAC clones, aided by a pooling strategy, overcame difficulties associated with high heterozygosity of the genome. The genome encodes about 23,300 genes, including many previously thought to be vertebrate innovations or known only outside the deuterostomes. This echinoderm genome provides an evolutionary outgroup for the chordates and yields insights into the evolution of deuterostomes.
