The synthesis of heat-shock proteins after a decrease in translational capacity in Escherichia coli.

View original source ↗Export metadata ↓

Abstract

Various conditions which decrease translational capacity and enhance the synthesis of ribosomal components were analysed with respect to the synthesis of heat-shock proteins in Escherichia coli: (a) deprivation of streptomycin from a streptomycin-dependent mutant, (b) addition of tetracycline to a partially tetracycline-resistant strain, and (c) nutritional shift-up conditions. In all cases, the rate of synthesis of the heat-shock proteins DnaK, GroEL and C62.5 decreased while the synthesis of ribosomal components increased. Thus inhibition of ribosome formation or a decrease in translational capacity do not induce the stress proteins, but have the opposite effect.

Assembly of a mediator/TFIID/TFIIA complex bypasses the need for an activator.

Transcription in eukaryotic cells requires the remodeling of chromatin and the assembly of functional preinitiation complexes (PICs), which contain the general transcription factors (GTFs), RNA polymerase II (Pol II), and coactivators. Genetic and biochemical studies have implicated the multisubunit Mediator coactivator complex (Med) as a critical component of the PIC, a direct target of activators, and a checkpoint for regulated gene expression during differentiation, development (reviewed in ), signaling, and oncogenesis. In this report, we show that a complex containing the activator GAL4-VP16, Med, and TFIID/TFIIA (DA) recruits pol II and the remaining GTFs to a model promoter in vitro. A preassembled DAMed complex bypasses the requirement for an activator. We also demonstrate that coordinated assembly of DAMed is essential to establishing a functional PIC. We conclude that the DAMed complex generates a platform that supports activated levels of PIC assembly and transcription.

Functional and structural proteomics: a critical appraisal.

The notion of functional proteomics (description of changes in protein expression during differentiation of cells) and structural proteomics (elucidation of the primary structure of the components in the proteomic pattern) is reviewed. Quantitative and qualitative aspects of the proteome analysis are discussed and evaluated. A list of projects is given that are of high priority for the elucidation of the proteome. This includes, e.g., the study of the repertoire of the proteome and the description of molecular pathways during the clonal cell replication. The paper re-evaluates a number of methodological issues, such as the comparison of the use of Ampholines and Immobilines, various staining procedures and labeling procedures.

Characterization and functionality of CXCR4 chemokine receptor and SDF-1 in human corneal fibroblasts.

PURPOSE: The aim of this study was to investigate whether cultured human corneal fibroblasts express functional chemokine CXCR4 receptors on their cell surface and to determine the presence of its specific ligand, SDF-1 (CXCL12), in human corneal fibroblasts. METHODS: Human corneal fibroblast cultures were obtained using human donor corneas. CXCR4 receptors were characterized using binding studies and autoradiography with [125I]SDF-1. The functionality of CXCR4 receptors was assessed by intracellular calcium measurement using a dynamic imaging microscopy system. CXCR4 and SDF-1 mRNA were detected in human corneal fibroblasts using reverse transcriptase polymerase chain reaction (RT-PCR). The CXCR4 protein was detected by western blot analysis. RESULTS: [125I]SDF-1 specifically bound to cultured corneal fibroblasts with a KD value of 8.3+/-1.2 nM. The presence of CXCR4 was confirmed by autoradiography of the radioligand on slices of corneal stroma. SDF-1 induced a rapid and transient intracellular calcium increase in cultured corneal fibroblasts that was blocked by the specific antagonist bicyclam. Moreover, a 48 kDa protein was detected by western blot analysis of corneal fibroblast extracts, using a specific CXCR4 polyclonal antibody. RT-PCR showed the expression of both CXCR4 and SDF-1 mRNAs in human corneal fibroblasts. CONCLUSIONS: These results indicate for the first time that cultured human corneal fibroblasts express the chemokine receptors CXCR4 and its ligand SDF-1. This latter might exert physiological effects on the cornea and could be involved in pathological conditions such as corneal angiogenesis.
