Project description:Endozoicomonas are prevalent, abundant bacterial associates of marine animal hosts, including corals. Their role in holobiont health and functioning, however, remains poorly understood. To identify putative interactions within the coral holobiont, we characterized a novel Endozoicomonas isolate and assessed its transcriptomic and proteomic responses to tissue extracts of its native host, the Red Sea coral Acropora humilis, at control and elevated temperatures. We show that host cues stimulated differential expression of genes assumed to be involved in the modulation of the host immune response by Endozoicomonas, such as flagellar assembly genes, ankyrins, ephrins, and serpins. Proteome analysis revealed the upregulation of vitamin B1 and B6 biosynthetic as well as glycolytic processes by Endozoicomonas in response to host cues. We further demonstrate that the inoculation of A. humilis with its native Endozoicomonas strain resulted in enhanced holobiont health metrics, such as host tissue protein content and algal symbiont photosynthetic efficiency. Behavioral, physiological, and metabolic changes in Endozoicomonas may be key to the onset and function of mutualistic interactions within the coral holobiont, and our results suggest that the priming of Endozoicomonas to a symbiotic lifestyle may involve modulation of host immunity and the exchange of essential metabolites with other holobiont members. Consequently, Endozoicomonas presumably plays an important role in holobiont nutrient cycling and may therefore be implicated in its health, acclimatization, and ecological adaptation.

Project description:Aging is a multifactorial process that results in progressive loss of regenerative capacity and tissue function while simultaneously favoring the development of a large array of age-related diseases. Evidence suggests that the accumulation of senescent cells in tissue promotes both normal and pathological aging. Oxic stress is a key driver of cellular senescence. Because symbiotic long-lived reef corals experience daily hyperoxic and hypoxic transitions, we hypothesized that these long-lived animals have developed specific longevity strategies in response to light. We analyzed transcriptome variation in the reef coral Stylophora pistillata during the day–night cycle and revealed a signature of the FoxO longevity pathway. We confirmed this pathway by immunofluorescence using antibodies against coral FoxO to demonstrate its nuclear translocation. Among genes that were specifically up- or downregulated on exposure to light, human orthologs of two “light-up” genes (HEY1 and LONF3) exhibited anti-senescence properties in primary human fibroblasts. Therefore, these genes are interesting candidates for counteracting skin aging. We propose a large screen for other light-up genes and an investigation of the biological response of reef corals to light (e.g., metabolic switching) to elucidate these processes and identify effective interventions for promoting healthy aging in humans.

Project description:Over the past several decades, corals worldwide have been affected by global warming, experiencing severe bleaching events that have often lead to coral death. The symbiotic Red Sea coral Stylophora pistillata is considered an opportunistic ‘r’ strategist, thriving in relatively unstable and unpredictable environments, and it is considered a stress-tolerant species. This study aimed to examine S. pistillata gene expression and to clarify the cellular pathways that are active during short-term heat stress caused by an increase from 24°C to 34°C over a 10-day period. Total RNA was extracted from heat-stressed coral fragments, labeled and hybridized against a designated S. pistillata custom microarray containing approximately 12,000 genes. Our results show that the heat stress reaction was sighted from 32°C and intensified significantly after 34°C treatment. Protein interaction networks of up- and down-regulated genes were constructed. The main clustering groups of up-regulated genes were ER stress and ER protein folding, cell cycle, ubiquitin-mediated proteolysis, cell death and cell death regulation and cellular stress response genes. These genes were enriched in cellular pathways related to the unfolded protein response (UPR) in the ER, ER-associated degradation (ERAD) and ubiquitin-mediated proteolysis. An analysis of the down-regulated genes yielded different clusters of genes related to extracellular matrix and actin organization, collagen, negative regulation of cell death and the Notch and Wnt signaling pathways. Genes encoding redox regulation proteins and molecular chaperones may be considered accurate “early warning genes”, while genes related to sensing and repairing DNA damage are severe heat-related genes. Here, we suggest that during short-term heat stress, S. pistillata might divert cellular energy into mechanisms such as UPR and ERAD at the expense of growth and biomineralization processes in an effort to recover from the stress.
