Abstract:
Satisfactory homogenization of a tissue is a necessary prerequisite to any fractionation schedule. A detailed protocol is given for rat liver because of the widespread use of this tissue. Although this technique should be broadly applicable to any soft tissue and to any subsequent fractionation procedure, there are certain tissues and applications that require either minor or extensive modification. Some of these points are addressed in the Notes section.

Abstract:
l-Ornithine decarboxylase provides de novo putrescine biosynthesis in mammals. Alternative pathways to generate putrescine that involve ADC (l-arginine decarboxylase) occur in non-mammalian organisms. It has been suggested that an ADC-mediated pathway may generate putrescine via agmatine in mammalian tissues. Published evidence for a mammalian ADC is based on (i) assays using mitochondrial extracts showing production of 14CO2 from [1-14C]arginine and (ii) cloned cDNA sequences that have been claimed to represent ADC. We have reinvestigated this evidence and were unable to find any evidence supporting a mammalian ADC. Mitochondrial extracts prepared from freshly isolated rodent liver and kidney using a metrizamide/Percoll density gradient were assayed for ADC activity using l-[U-14C]-arginine in the presence or absence of arginine metabolic pathway inhibitors. Although 14CO2 was produced in substantial amounts, no labelled agmatine or putrescine was detected. [14C]Agmatine added to liver extracts was not degraded significantly indicating that any agmatine derived from a putative ADC activity was not lost due to further metabolism. Extensive searches of current genome databases using non-mammalian ADC sequences did not identify a viable candidate ADC gene. One of the putative mammalian ADC sequences appears to be derived from bacteria and the other lacks several residues that are essential for decarboxylase activity. These results indicate that 14CO2 release from [1-14C]arginine is not adequate evidence for a mammalian ADC. Although agmatine is a known constituent of mammalian cells, it can be transported from the diet. Therefore l-ornithine decarboxylase remains the only established route for de novo putrescine biosynthesis in mammals.

Abstract:
Abstract Measurement of folate in animal tissues is expensive and time-consuming. A fluorescence polarization assay has been developed that allows the rapid and inexpensive quantification of folate in various animal tissues. The concentration of tissue folate is determined by its ability to compete with the binding of Alexa-660-folate to bovine milk folate binding protein. The technique uses a few milligrams of material and is amenable to automated screening in 384-well microplates. Using this approach, the folate concentration in mouse liver, kidney & brain was found to be 21.4, 4.22 and 0.73 nanomoles/g fresh tissue, respectively. Packed human erythrocytes were found to contain 1.31 mM folate. These estimates are similar to published folate values for these tissues. Ascorbate was not included in the assay buffer because of its pro-oxidant effects in iron rich tissues such as erythrocytes and liver. The assay is homogeneous, completed within a few hours of the availability of the samples, and will enable the high throughput analyses of folate in human and animal samples.

Abstract:
Gangliosides are series of glycosphingolipids containing sialic acids in the oligosaccharide portion in mammalian cells. Gangliosides are a component of cellular membranes and play roles in modulating membrane function and the activity of membrane proteins. Abnormal expression and metabolism of gangliosides lead to the onset of several conditions in humans, such as neurologic diseases, diabetes, and cancer. A number of studies have been carried out to date to investigate the role of gangliosides in these diseases, and the effect of diet on tissue expression of gangliosides has recently become a topic of interest in this field. As gangliosides are degraded in the intestinal tract, ingested food-derived gangliosides are not directly absorbed into tissues in vivo, but the degradation products can be absorbed and affect ganglioside expression in the tissues. Recent studies have also shown that the expression of gangliosides in tissue cells can be indirectly induced by controlling the expression of ganglioside metabolism-related genes via the diet. These results indicate that dietary control can regulate the expression levels of gangliosides in tissues, which is expected to play a role in preventing and treating ganglioside-related diseases. This review introduces recent studies on the effect of diet on the expression of gangliosides in tissues, with a focus on our findings.

Abstract:
The development of energy metabolism of mammalian tissues was assessed in the tammar wallaby Macropus eugenii by the measurement of mitochondrial parameters in the liver, heart, kidney, and brain. Tissues taken from wallabies (n = 27) ranging from 10-day-old pouch young (weighing approximately 4 g) to adults (averaging 6.2 kg) were weighed and fixed, and mitochondrial volume and mitochondrial membrane surface area (MMSA) were determined by quantitative electron microscopy techniques. Developmental changes in these parameters were analyzed chronologically and allometrically. Relative growth rates of all four tissues decreased during development. Liver and heart showed constant allometric growth throughout development, whereas kidney and brain showed biphasic allometric growth. Tissue metabolic intensity assessed by MMSA (m2/cm3 tissue) was constant in liver, showed a threefold increase in brain during pouch life, showed a fourfold increase in the heart between 100 and 200 days of age, and showed a twofold increase in the kidney at the end of pouch life. In all tissues, adult levels of tissue metabolic capacity were present at pouch exit. In all four tissues, total MMSAs were at "reptilian" levels at birth and gradually increased to "mammalian" levels. Each tissue exhibited a different developmental timetable. When the total MMSAs for all four tissues were summed there was a similar pattern of allometric development between summed MMSA and whole animal metabolic rate.

Abstract:
Carnosine, homocarnosine and anserine were found to be present in rat quadriceps, gastrocnemius, and pectoral muscles, and in spinal cord and brain. These dipeptides could not be detected in heart, lung, kidney, liver or testes. A method for the determination of carnosine and related compounds, using reverse phase HPLC, has been developed. A novel colorimetric method, based on the formation of a coloured complex with Cobalt (II), was also developed for the determination of carnosine. The distribution of carnosine synthetase and homocarnosine synthetase in rat spinal cord, brain or skeletal muscles was studied. Carnosine synthetase was also shown to be responsible for anserine synthesis. On gel-filtration, carnosine synthetase separates into two active fractions (Mr 250,000 and 120,000). Homocarnosine synthetase has a Mr of 115,000. A requirement by carnosine synthetase for NAD+ and glucose was confirmed. Pyridoxal-5-monophosphate effectively replaced the requirement for glucose; a hypothesis is presented to explain this. Ca2+ ions were shown to activate carnosine synthetase but not homocarnosine synthetase. Significant effects on carnosine and homocarnosine synthetase from rat brain and gastrocnemius were produced by 5'-AMP, 5'-cAMP, 5'-GMP and 3',5'-cGMP. Carnosine synthetase activity, both from rat brain and from gastrocnemius, was inhibited by α-alanine which was shown to be an alternative substrate to β-alanine resulting in formation of L-α-alanyl-L-histidine. Carnosinase and homocarnosinase were partially purified from brain and from gastrocnemius. Carnosinase has a M_r of 120,000 and 50,000 and was activated by dithioerythritol. Homocarnosinase has a M_r of 54,000. Carnosinase was insensitive to thiol compounds and a range of metal ions. Homocarnosinase was activated by Co^2+ ions and was inhibited by thiol compounds. The K_m for carnosinase and homocarnosinase was found to be 4.0 mM and 1.0 mM, respectively. Carnosine, homocarnosine and anserine were shown to have no effect on hexokinase, phosphofructokinase, α-oxoglutarate, NAD+-isocitrate dehydrogenase and pyruvic dehydrogenase.

Abstract:
The Drosophila Cut and mammalian Cut-like proteins contain a unique homeodomain and triplicated DNA binding regions, called the Cut repeats. The Cut proteins define a distinct class of homeodomain proteins with multiple DNA binding domains. In this project I investigated Cut mRNA expression in adult mouse tissues, using RNase and S1 nuclease mapping. Cut mRNA was found to be widely expressed in both adult mouse tissues and cultured cells. Actinomycin chase experiments indicated that Cut mRNAs have a short half-life. In addition to the Cut mRNA found in normal cells, another Cut mRNA species was detected in some tumor cell lines, including HOS (human osteosarcoma), RAJI and RAMOS (Burkitts lymphomas). These transcripts diverged in the region immediately after the Cut homeobox and were generated as a result of an alternative splicing or polyadenylation event. In this study I also cloned and characterized the murine Cut cDNA (mCut). Sequence comparison with the hCut revealed a high degree of homology especially within evolutionary conserved domains. However, there were two regions of sequence divergence, one between Cut repeat I and Cut repeat II and the other just downstream of the homeodomain. Domain swapping experiments revealed that the carboxyl terminal regions of both mCut and hCut function as active repression domains. Interestingly, the fusion protein containing mCut which diverges from hCut in a portion of this carboxyl terminal region acts as a much stronger repressor of transcription.

Abstract:
This study was initiated to examine the effects of ciguatera toxins on fish tissues and to attempt to locate the binding site of ciguatera toxin in the mammalian brain. Previous studies indicated that ciguatera toxins produced histopathological effects in mice (Coombe et al., 1987; Hassan et al., 1991; Terao et al., 1988; Terao et al., 1989a). Capra et al. (1988) examined the effects of ciguatera toxin on fish tissues, intestine and gill. The tissues examined in this study were the liver, intestine and gill. The initial toxin, supplied by Flowers (1989) produced histopathological changes in the majority of tissues examined. Changes included disruption to the gill epithelium, disruption to the epithelial layer in the intestine and necrosis and glycogen loss in the liver. Later experiments utilised toxins extracted by the author and those supplied by the Professors Miller and Tindall from the Southern Illinois University. These toxins produced no changes in the gill and very few in the intestine. Changes in the liver included necrosis and complete loss of glycogen. Three species of fish used were, Pomacentrus wardi, Chromis nitida and Dascyllus aruanus. The latter two species are planktivores, and P. wardi is a browser. C. nitida was significantly more susceptible to the toxin then P. wardi, according to the recorded death times. The attempt to locate the binding site of ciguatera toxins in the mouse brain was unsuccessful. Ciguatera toxin has been shown to have a nonspecific affinity for IgG (Emerson et al., 1983). An immunocytochemical method was used to try and locate the ciguatera binding sites. A labelled avidin-biotin method was used (Guesdon et al., 1979). Two methods of preservation were attempted, formalin fixed and frozen sections. Methods of exposing the tissue to the toxin attempted were, pre- and post-preservation for frozen sections and prepreservation for the parafin sections.

Abstract:
Systems for controlling gene expression in mammalian cells have a wide range of applications in medicine, biotechnology and basic science. An ideal gene regulatory system would allow for precise and specific control over the magnitude and kinetics of gene expression in space and time, while also exerting minimal influence on other genes and cellular components. Several gene regulatory systems have been developed in which orthogonal transcription machinery from prokaryotes or insects has been imported into mammalian cells and used to control the expression of a specific gene. Despite the transformative impact of these systems in biomedical and biological research, several limitations of these technologies restrict the scope of possible applications. For example, gene expression in these systems is controlled by a freely diffusible small molecule, such as an antibiotic or steroid. Consequently, it is not possible to achieve spatial control over gene expression within cell culture, tissues, or whole organisms. This is in contrast to natural mechanisms of biological regulation in which spatial control is critical, such as developmental patterning and tissue morphogenesis. Second, dynamic gene regulation requires the removal of these small molecules, which may be slow, laborious, and/or impractical for a particular application. To overcome these limitations, we have engineered an optogenetic system in which the magnitude of gene expression in human cells can be finely tuned by photoregulated synthetic transcription factors.

Abstract:
We developed a functional high throughput 3D microfluidic living cell array (MLC) for anti-cancer drug screening and mechanism discovery. Contemporary drug screening methods suffer from low sample throughput and lack of abilities of mimicking the 3D microenvironment of mammalian tissues. The poor performance of anti-cancer drugs limits the efficacy at controlling the complex disease system like cancer. Systematic studies of apoptotic signaling pathways can be prominent approaches for searching active and effective treatments with less drug resistance. Hence, innovative bio-devices are needed to represent tumor microenvironment to understand the molecular signatures of apoptosis for testing new anticancer therapies targeting apoptosis. Our novel 3D MLC design is the prototype of a high-throughput drug screening platform targeting apoptotic signaling pathways.

Abstract:
Vascular structure — a network of convective paths — is a ubiquitous element in multicellular, living systems. The key function of vascular structure in animals and plants is mediation of convective mass transfer over macroscopic distances; this transfer allows an organism to monitor and control the chemical state of its tissues. In our laboratory, we are developing methods to embed and operate microfluidic systems within tissue-like materials in order to capture this function for both biological and non-biological applications. I will present two examples to illustrate our efforts: 1) Capillary beds for the culture of mammalian cells in three-dimensions. In this section, I will discuss the development of methods both to fabricate synthetic capillary beds and to grow them directly out of endothelial cells. I will highlight how simple ideas from continuum mechanics and material science have guided our efforts. 2) Synthetic xylem networks that allow for the transpiration of water at large negative pressures. I will point out the unusual thermodynamic and transport phenomena that are involved in the transpiration process in plants. I will then present our perspectives on the design criteria for systems — synthetic and biological — that mediate this process. Finally, I will describe our experiments with “synthetic trees” in which we have reproduced the main features of transpiration. I will conclude with perspectives on applications and generalizations of both these classes of vascularized materials.

Abstract:
Defobrotide(D) a natural polydeoxyribonucleotide of mammalian lung origin is a new substance with no anticoagulant or hemodinamic effects?it has shown considerable profibrinolytic and antithrombotic activities. The ability of (D) to increase generation of prostaci-clmCPGI2) from vascular tissue has been demonstrated; this substance also promotes substantial release from vascular tissues of a plasminogen activator factor which plays an important role in preventing thrombotic oclusion of vascular segments.Widely accepted therapies in deep venous thrombosis and Acute Thromboflebitis (A.f.; are based on anticoagulant treatments (heparin and/or oral anticoagulant agentsWe have evaluated the efficacy of (D> in (A.T.) vs. heparin in 40 pts.(28 females 12 males;mean age=50) with an open randomized study.Group A:20 pts.have been administered CD; 200mg.four times a day l.m. for 10 days.Group B:20 pts.have been administered Sodic Heparin 30000 U.I. intravenously with successive dosage based upon APTT values.Both groups have been treated with an oral anti coagulant agentCacenocoumaro1) after the tenth day.No clinical differences between the treatments have been observed and in no pts. treated with CD; we noted significant changes m laboratory parameters evaluated: complete blood count,glycemia BUN creatinine ALT AST LDH.Clinical eficacy was excellent in both groups also supported by augmented fibrinolysis and instrumental improvement(strain-gauge plethismography;.The absolute safety of (D> therapy shows its possible alternative role when compared to heparin treatment in (A.T.> of any origin.

Abstract:
Abstract The IR sensitive membrane of the Crotaline pit organ was modeled numerically to help interpret electrophysiologic measurements of the pit organ response to a calibrated infrared source simulating a biological target. The model results are compared to electrophysiologic measurements for an on-axis exposure (target normal to the pit organ axis, oriented for maximum response). Additional model studies were conducted to: 1) estimate the field of view of the pit organ and 2) estimate the expected temperature rise in the membrane from the target at varying distances. The pit organ model was based on detailed measurements of its geometry. The membrane illumination irradiance difference from background thermal radiation (in W/mm2) was calculated from a quasi-analytical solution for the radiation coupling factor, Fjj. The illumination function was used to estimate temperature rise neglecting infrared heat transfer between the membrane and surrounding pit organ tissues. That is, the membrane was assumed in thermal steady state with the snake body and the environment outside of the target. The mammalian target is thus assumed to represent a small perturbation to the thermal steady state condition. This matches the electrophysiologic data, and is reasonable since the snake is cold blooded and snake body temperature is very close to its surroundings. The membrane includes blood flow effects, but it turns out that the membrane blood flow is strictly capillary in nature and changes the effective lateral thermal conductivity rather than providing significant heat transfer. The membrane is “optically thin”, being only about 5 wavelengths in thickness, and the specific optical properties of the interior layers were estimated from relative water content.
