Phorbol-12-myristate-13-acetate (PMA), a potent tumor promoter, was shown to have opposite effects on the cellular morphology and steady-state levels of beta-actin mRNA in embryonic chicken muscle fibroblasts and sternal chondrocytes. When fibroblasts were treated with PMA, they formed foci of densely packed cells, ceased to adhere to culture plates, and had significantly reduced levels of beta-actin mRNA and protein. Conversely, when treated with PMA, floating chondrocytes attached to culture dishes, spread out, and began to accumulate high levels of beta-actin mRNA and proteins. In the stern

Abstract:
Subcellular regulation of protein synthesis requires the correct localization of messenger RNAs (mRNAs) within the cell. In this study, we investigate whether the axonal localization of neuronal mRNAs is regulated by extracellular stimuli. By profiling axonal levels of 50 mRNAs detected in regenerating adult sensory axons, we show that neurotrophins can increase and decrease levels of axonal mRNAs. Neurotrophins (nerve growth factor, brain-derived neurotrophic factor, and neurotrophin-3) regulate axonal mRNA levels and use distinct downstream signals to localize individual mRNAs. However, myel

Translational efficiency of a minor group of mRNAs is regulated by serum levels in 3T6 fibroblasts. Included within this group is the poly(A)-binding protein (PABP) mRNA. We analyzed the distribution of PABP mRNA in polysome profiles and found a large percentage of this mRNA to be translationally repressed in both actively growing (~ 60%) and resting cells (~ 70%). Elevated serum levels induced a distinct bimodal distribution of this mRNA between actively translated and repressed fractions.

Abstract:
Human plasminogen activator inhibitor type-1 is an Mr∼54,000 protein which specifically inhibits urokinase-type (u-PA) and tissue-type (t-PA) plasminogen activators. During inhibition, u-PA and t-PA convert PAI-1 to an inactive form with Mr∼50,000. We have determined the amino-terminal amino acid sequence of native and converted PAI-1, and isolated and partly sequenced PAI-1 cDNA. The data show that the conversion of PAI-1 consists of cleavage of an Arg-Met bond 33 residues from the carboxy-terminus, thus localizing the reactive center of the inhibitor to that position, and identifying PAI-1 a

Abstract:
The hormonal regulation of plasminogen activator (urokinase type (u-PA) and tissue-type (t-PA)) biosynthesis plays an important role in fibrinolysis and extracellular matrix turnover during invasive growth and cell migration. Recently, two genetically distinct inhibitors of both PA's (PA inhibitor 1 (PAI-1) and PA inhibitor 2 (PAI-2)) have been described which may contribute to the modulation of matrix stability. We have employed cloned cDNA probes to study the regulation of biosynthesis of these proteins in the human fibrosarcoma line HT1080. These cells constitutively express high levels of

Abstract:
Abstract It is believed that bone cells can sense mechanical loading and alter bone external shape and internal structure to efficiently support the load bearing demands placed upon it. However, the mechanism by which bone cells sense and respond to their mechanical environment is still poorly understood. In particular, the load-induced signals to which bone cells respond, e.g. fluid flow, substrate deformation, electrokinetic effects etc., are unclear. Furthermore, there are few studies focused on the effects of physiological strain (strain &amp;lt; 0.5%, Burr, 1996; Owan, 1997) on bone cells

Original objectives: The long term objective of the project is to achieve higher content of protein in the milk of ruminants by modulating the translational machinery in the mammary gland. The first specific aim of the BARD proposal was to characterize responsiveness of various experimental systems to combination of lactogenic hormones and amino acids with particular emphasis on discrimination between the control of total protein synthesis and milk protein synthesis. Based on the results, we planned to proceed by characterizing the stage of protein synthesis in which the stimulation by lactoge

Original objectives: The long-term goal of the research is to achieve higher protein content in the milk of ruminants by modulating the translational apparatus of the mammary gland genetically, nutritionally, or pharmacologically. The short-term objectives are to obtain a better understanding of 1) the role of amino acids (AA) as regulators of translation in bovine and mouse mammary epithelial cells and 2) the mechanism responsible for the synergistic enhancement of milk-protein mRNA polyadenylation by insulin and prolactin.

Abstract:
CRISPR gene editing is a molecular technology that can be used to silence gene expression. In this experiment, genes that are known to play a role in lipid accumulation in hepatocytes were targeted. Specifically, levels of fatty acid transport proteins 2 and 5 (FATP2 &amp; 5) have been shown to be elevated in cases of non-alcoholic fatty liver disease. The goal of this experiment was to reduce expression of these genes by using a dead Cas9 (dCas9) protein with an attached inhibitory domain (KRAB) that acts on the promotor region. When measuring the mRNA expression, it was determined that the l

Abstract:
The steady-state level of a given mRNA is determined by its rates of transcription and degradation. The stabilities of chloroplast mRNAs vary during plant development, in part regulating gene expression. Furthermore, the fitness of the organelle depends on its ability to destroy non-functional transcripts. In addition, there is a resurgent interest by the biotechnology community in chloroplast transformation due to the public concerns over pollen transmission of introduced traits or foreign proteins. Therefore, studies into basic gene expression mechanisms in the chloroplast will open the door

Abstract:
The main goal of this research plan was to elucidate regulatory mechanisms controlling the development, function of the bovine corpus luteum (CL). The CL contains two different sterodigenic cell types and therefore it was necessary to obtain pure cell population. A system was developed in which granulosa and theca interna cells, isolated from a preovulatory follicle, acquired characteristics typical of large (LL) and small (SL) luteal cells, respectively, as judged by several biochemical and morphological criteria. Experiments were conducted to determine the effects of granulosa cells removal

In lupus nephritis, conventional tests like urinalysis or serum creatinine remain inadequate for patient care. In this proposal, we focused on non-invasive tools like blood and urine mRNAs or proteins. We chose candidate genes involving regulatory T-cell, B-lymphocyte signatures or vascular protective factors. Expression of regulatory cell signature (FOXP3) in peripheral blood mononuclear cells is associated with activity of lupus nephritis. We found FOXP3 mRNA levels in PBMCs from patien

Abstract:
The senescence of carnation (Dianthus caryophyllus L.) flowers is associated with increased production of the phytohormone ethylene, which in turn serves to initiate and regulate the processes involved in programmed petal death. We investigated the regulation of ethylene production and petal senescence in carnation. Several carnation genotypes were identified that exhibited extended vase-life in comparison to flowers from typical commercial cultivars. The capacity of these genotypes to produce ethylene during postharvest vase-life and to respond to exogenous ethylene was investigated. Several
