Abstract (sommario):

Integrins constitute a family of membrane-spanning, heterodimeric proteins that mediate adhesive interactions between cells and surrounding extracellular matrices (or other cells) and participate in signal transduction. We are interested in assessing integrin functions in the context of developing Drosophila melanogaster. This report, using mutants of the beta PS subunit encoded by the myospheroid (mys) locus, analyzes the relationships between integrin protein structure and developmental functions in an intact organism. As a first step in this analysis, we demonstrated the ability of a fragment of wild-type mys genomic DNA, introduced into the germ line in a P-element vector P[mys+], to rescue phenotypes attributed to lack of (or defects in) the endogenous beta PS during several discrete morphogenetic events. We then produced in vitro a series of modifications of the wild-type P[mys+] transposon, which encode beta PS derivatives with mutations within the small and highly conserved cytoplasmic domain. In vivo analysis of these mutant transposons led to the following conclusions. (1) The cytoplasmic tail of beta PS is essential for all developmental functions of the protein that were assayed. (2) An intron at a conserved position in the DNA sequence encoding the cytoplasmic tail is thought to participate in important alternative splicing events in vertebrate beta integrin subunit genes, but is not required for the developmental functions of the mys gene assayed here. (3) Phosphorylation on two conserved tyrosines found in the C terminus of the beta PS cytoplasmic tail is not necessary for the tested developmental functions. (4) Four highly conserved amino acid residues found in the N-terminal portion of the cytoplasmic tail are important but not critical for the developmental functions of beta PS; furthermore, the efficiencies with which these mutant proteins function during different morphogenetic processes vary greatly, strongly suggesting that the cytoplasmic interactions involving PS integrins are developmentally modulated.

Abstract (sommario):

This rejoinder acknowledges the empirical gaps and theoretical/theological disharmony highlighted in the three selected commentaries on Place Spirituality (PS), but we defend our central argument about the developmental pathways of PS. First, we provide an overview of recent studies on PS, highlighting what has been done so far in the field. Second, we draw from the commentaries to advance the understanding of PS in relation to three world religions: Islam, Christianity and Hinduism. Third, we evaluate the normative aspects of PS as a transactional versus transitional phenomenon. Finally, we defend the two contested developmental pathways to PS, involving the compensation and correspondence working models of attachment, while complementing these models using the motivational systems framework. We maintain that these models are relevant for understanding the relationship between religious attachment and place attachment among religious and non-religious people. Recommendations for further studies are made in relation to the broader implications of PS.

Abstract (sommario):

This three-part investigation conducted a comprehensive analysis of 213 Australian and Canadian athletes’ developmental trajectories, training histories, and experiences in organized sports from 18 Paralympic sports (PS). While athletes with early-onset impairments (i.e., congenital, preadolescent) reached milestones and commenced various types of training at a significantly younger age than athletes with later-onset impairments (i.e., early adulthood, adulthood), the latter groups progressed through their careers and incorporated various trainings at a faster pace (i.e., fewer years). Preferences to certain training conditions varied between groups. Eighty-two percent of the athletes with acquired impairments had experience in able-bodied sports before the onset of their impairment, with 70% noting involvement in sports similar to their current PS. The participation rates (38%) and sport similarity (53%) were lower in PS. The amalgamation of findings from this series of studies highlights the complexity associated with PS athletes’ development and demonstrates the importance of taking an individualized approach.

Abstract (sommario):

Developmental engineering (DE) aims to culture mammalian cells on corresponding modular scaffolds (scale: micron to millimeter), then assemble these into functional tissues imitating natural developmental biology processes. This research intended to investigate the influences of polymeric particles on modular tissue cultures. When poly(methyl methacrylate) (PMMA), poly(lactic acid) (PLA) and polystyrene (PS) particles (diameter: 5–100 µm) were fabricated and submerged in culture medium in tissue culture plastics (TCPs) for modular tissue cultures, the majority of adjacent PMMA, some PLA but no PS particles aggregated. Human dermal fibroblasts (HDFs) could be directly seeded onto large (diameter: 30–100 µm) PMMA particles, but not small (diameter: 5–20 µm) PMMA, nor all the PLA and PS particles. During tissue cultures, HDFs migrated from the TCPs surfaces onto all the particles, while the clustered PMMA or PLA particles were colonized by HDFs into modular tissues with varying sizes. Further comparisons revealed that HDFs utilized the same cell bridging and stacking strategies to colonize single or clustered polymeric particles, and the finely controlled open pores, corners and gaps on 3D-printed PLA discs. These observed cell–scaffold interactions, which were then used to evaluate the adaptation of microcarrier-based cell expansion technologies for modular tissue manufacturing in DE.

Abstract (sommario):

Abstract Mindfulness and emotion regulation through music listening are skills that share some attributes with the skill of positive solitude (PS; defined as an inner choice to dedicate time to a meaningful, enjoyable activity or experience managed by oneself, with or without the presence of others). Nevertheless, little is known about their relationship with PS in the second half of life. Hence, we recruited a convenience sample of community-dwelling adults in the second half of life (N = 123; M = 68.63, SD = 10.99), who completed self-report measures of demographics, emotion regulation through music, mindfulness, and PS. A hierarchical linear regression demonstrated significant positive associations between emotion regulation through music listening and PS, and between mindfulness and PS. Moreover, age moderated the relationship between mindfulness and PS. This relationship was found to be positive and significant only among older adults. These findings support the study’s hypotheses and emphasize the contribution of the current research to developmental research on PS in the second half of life.

Abstract (sommario):

BACKGROUND: Menière disease (MD) and SLC26A4 related deafness (Pendred syndrome (PS) or DFNB4) are two different inner ear disorders which present with fluctuating and progressive hearing loss, which could be a direct consequence of endolymphatic hydrops. OBJECTIVE: To present similarities between both pathologies and explore how the concept of hydrops may be applied to PS/DFNB4. METHODS: Review of the literature on MD, PS/DFNB4 and mouse model of PS/DFNB4. RESULTS: MD and PS/DFNB4 share a number of similarities such as fluctuating and progressive hearing loss, acute episodes with vertigo and tinnitus, MRI and histological evidence of endolymphatic hydrops (although with different underlying mechanisms). MD is usually diagnosed during the fourth decade of life whereas PS/DFNB4 is congenital. The PS/DFNB4 mouse models have shown that biallelic slc26a4 mutations lead to Na+ and water retention in the endolymph during the perinatal period, which in turn induces degeneration of the stria vascularis and hearing loss. Crossing clinical/imagery characteristics and animal models, evidence seems to support the hypothesis of PS being a foetal hydrops. CONCLUSIONS: When understanding PS/DFNB4 as a developmental hydrops, treatments used in MD could be repositioned to PS.

Abstract (sommario):

The two Drosophila position-specific (PS) integrins are expressed on complementary sides of sites where different cell layers adhere to each other, such as the attachments of the embryonic muscles to the epidermis. While there is suggestive evidence that the PS integrin-mediated adhesion is via the extracellular matrix, it is also possible that it occurs through the direct interaction of the two integrins, alpha PS1 beta PS and alpha PS2 beta PS. To help distinguish between these possibilities a comparison between the phenotypes caused by the absence of the beta PS subunit and the absence of one of the PS alpha subunits, alpha PS2, has been made. Two pieces of evidence are provided that prove that the alpha PS2 subunit is encoded by the locus inflated (if). Firstly, three new if alleles have been isolated, each of which is associated with a molecular lesion in the alpha PS2 gene, and each of which results in the complete loss of if activity. Secondly, a 39 kb fragment of genomic DNA that encompasses the alpha PS2 gene completely rescues if mutations when introduced into the germline by P-element-mediated transformation. A comparison of the null inflated phenotype with that of the locus that encodes the beta PS subunit, myospheroid (mys), reveals that while the beta PS subunit is required for the adhesion of the epidermis along the dorsal midline, the alpha PS2 subunit is not. In if mutant embryos, the muscles remain attached to the other cell layers significantly longer than in a mys mutant embryo. This shows that the alpha PS2 beta PS integrin only contributes part of the adhesive activity at the sites of PS integrin adhesion, and rules out a model where PS integrin function occurs solely by the direct interaction of the two PS integrins.

Abstract (sommario):

The Drosophila position-specific (PS) antigens are homologues of the vertebrate integrins, a family of transmembrane proteins that function in cell-matrix and cell-cell adhesion. The common beta subunit of PS integrins (PS beta) is encoded by the lethal(l)myospheroid gene (mys) and is required during wing, eye and muscle development. By expressing PS beta protein at defined developmental periods, we have shown that PS integrins are required throughout pupation, but not earlier, for normal development of wings. In contrast, the key requirement for PS integrins in eye development occurs only in the late pupa. Furthermore, PS integrins are apparently not required for the differentiation of the ommatidial cells; only for their organization. These results are consistent with roles for PS integrins in the interactions between the wing epithelia during the two phases of pupal wing expansion and in maintaining the attachment of a fully formed fenestrated membrane to the basement membrane of the retina. We have also examined the functional significance of alternative splicing of the transcript of the mys gene using P element-mediated transformation to introduce transgenes producing only one of the two spliced forms of PS beta. We find that either form is sufficient to rescue postembryonic mys phenotypes in the wing, eye and muscle but that both of the two splice forms are necessary to rescue the mys embryonic defects. This result indicates a requirement for the alternative splicing of mys during embryogenesis. The location of the alternative exons suggests that the two forms of the PS beta integrin subunit may interact with alternative alpha subunits and/or ligands.

Abstract (sommario):

The sphingoid long chain bases (LCBs) and their phosphorylated derivatives (LCB-Ps) are important signaling molecules in eukaryotic organisms. The cellular levels of LCB-Ps are tightly controlled by the coordinated action of the LCB kinase activity responsible for their synthesis and the LCB-P phosphatase and lyase activities responsible for their catabolism. Although recent studies have implicated LCB-Ps as regulatory molecules in plants, in comparison with yeast and mammals, much less is known about their metabolism and function in plants. To investigate the functions of LCB-Ps in plants, we have undertaken the identification and characterization of Arabidopsis genes that encode the enzymes of LCB-P metabolism. In this study the Arabidopsis At1g27980 gene was shown to encode the only detectable LCB-P lyase activity in Arabidopsis. The LCB-P lyase activity was characterized, and mutant plant lines lacking the lyase were generated and analyzed. Whereas in other organisms loss of LCB-P lyase activity is associated with accumulation of high levels of LCB/LCB-Ps and developmental abnormalities, the sphingolipid profiles of the mutant plants were remarkably similar to those of wild-type plants, and no developmental abnormalities were observed. Thus, these studies indicate that the lyase plays a minor role in maintenance of sphingolipid metabolism during normal plant development and growth. However, a clear role for the lyase was revealed upon perturbation of sphingolipid synthesis by treatment with the inhibitor of ceramide synthase, fumonisin B1.

Abstract (sommario):

Mammalian U2AF65 and UAP56 are required for prespliceosome (PS) formation. We tested the predictions that the yeast UAP56 homolog,SUB2, is required for the same step and functions collaboratively with MUD2, the yeast homolog of U2AF65. Unexpectedly, sub2-1 extracts accumulate PS-like complexes. Moreover, deletion of MUD2 exacerbates the cs phenotype ofsub2 alleles yet suppresses both the ts sub2-1and the lethal Δsub2 phenotypes. We propose that Sub2 functionally interacts with Mud2 both before and after PS formation. In the absence of Mud2, Sub2 function becomes dispensable.
