Deciphering Multi-Organ Protein Regulatory Strategies in Pelophylax nigromaculatus During Hibernation to Elucidate Energy Homeostasis Maintenance Mechanisms

ABSTRACT: Hibernation, a natural physiological state characterized by reduced energy expenditure, represents a survival strategy adopted by organisms to endure adverse environmental conditions such as low temperatures and food scarcity. Amphibians frequently endure harsh hibernation conditions characterized by low temperatures and hypoxia, yet they typically exhibit rapid physiological recovery upon arousal without sustaining permanent organ or tissue damage. These remarkable capabilities stem from specialized organ-protective mechanisms and adaptive physiological regulation unique to hibernating species. This study employed Data-Independent Acquisition (DIA) quantitative proteomics technology to conduct comprehensive quantitative proteomic and phosphoproteomic analyses of the kidneys, liver, and lungs in Pelophylax nigromaculatus during hibernation, followed by multi-dimensional analysis of the protein regulatory strategies. Our multidimensional analytical approach elucidated intricate protein regulatory strategies underlying this hypometabolic state. The findings provide substantial and reliable datasets for advancing molecular investigations into hibernation mechanisms in amphibians, while establishing a foundational framework for understanding the molecular regulation of low-energy metabolism in animals.

Project description:In this project, effects of chronic temperature changes on the transcriptome of the rainbow trout heart (Oncorhynchus mykiss) were examined. Ectothermic animals of north-temperate latitudes experience large seasonal changes in temperature which strongly affect the rate of body functions. To compensate for the effects of temperature changes ectotherms can respond to chronic temperature changes by increasing the quantity of tissue or enzyme needed for different physiological tasks, or by expressing proteins isoforms which are more appropriate for the new thermal conditions. On the other hand, proteins which are needed in lesser amounts in the new thermal regime could be depressed or down-regulated. Although expression of proteins can be changed by multiple mechanisms during synthesis and degradation, temperature dependent changes in transcription of genes is probably the most important factor in modifying the proteome of the tissues. Rainbow trout are active throughout their thermal tolerance range (0-25Â°C). Maintenance of adequate cardiac function at different thermal conditions requires a thorough change of the cardiac phenotype which appears as compensatory changes in relative heart mass, energy metabolism, nervous and humoral control of cardiac contractility and in electrical and mechanical properties of the trout heart. Such an extensive structural and functional remodeling of the heart probably necessitates both qualitative and quantitative changes among the numerous macromolecules which constitute the cardiac phenotype and cannot, therefore, be solely based on posttranslational modification of proteins but is expected to require differential gene expression. As a power supply of the circulatory system, the heart is in the focal point of physiological plasticity and sets limits for the activity level of the animal in different thermal conditions. Although several aspects of heart function have been studied in thermally acclimated fish and a number of structural changes have been noticed on exposure to different temperatures, the cellular and molecular mechanisms involved in chronic thermal stress of the fish heart are only partially elucidated. An interesting and poorly examined feature of the cold-acclimated phenotype of the trout heart is the increased heart mass which attenuates the depressive effect of low temperature on cardiac pump function. The heart is a complex organ composed of multiple tissues which together provide the system all necessary qualifications for cardiac pump function. In addition to the contractile and metabolic machinery of the cardiac myocytes, the amount and quality of the extracellular matrix also contribute to the properties of the heart as a muscular pump. Due to the complexity of the heart an enormous amounts of research efforts are needed to find out and examine all crucial aspects of cardiac plasticity required for thermal acclimation. In this regard the screening of gene expression by cDNA micro arrays might provide a broader view to genomic basis of cardiac remodeling under changing temperatures and aid to reveal the candidate genes which are important for thermal acclimation and which might remain unnoticed by traditional biochemical and physiological methods. In the present study we the steady-state effects of temperature acclimation on gene expression of the rainbow trout heart were screened by micro array analysis.

Project description:We aimed to investigate the human skeletal muscle (SkM) DNA methylome after exercise in low carbohydrate (CHO) energy balance (with high fat) compared with exercise in low-CHO energy deficit (with low fat) conditions. The objective to identify novel epigenetically regulated genes and pathways associated with ‘train-low sleep-low’ paradigms. The sleep-low conditions included 9 males that cycled to deplete muscle glycogen while reaching a set energy expenditure. Post-exercise, low-CHO meals (protein-matched) completely replaced (using high-fat) or only partially replaced (low-fat) the energy expended. The following morning resting baseline biopsies were taken and the participants then undertook 75 minutes of cycling exercise, with skeletal muscle biopsies collected 30 minutes and 3.5 hours post exercise. Discovery of genome-wide DNA methylation was undertaken using Illumina EPIC arrays and targeted gene expression analysis was conducted by RT-qPCR. At baseline participants under energy balance (high fat) demonstrated a predominantly hypermethylated (60%) profile across the genome compared to energy deficit-low fat conditions. However, post exercise performed in energy balance (with high fat) elicited a more prominent hypomethylation signature 30 minutes post-exercise in gene regulatory regions important for transcription (CpG islands within promoter regions) compared with exercise in energy deficit (with low fat) conditions. Such hypomethylation was enriched within pathways related to: IL6-JAK-STAT signalling, metabolic processes, p53 / cell cycle and oxidative / fatty acid metabolism. Hypomethylation within the promoter regions of genes: HDAC2, MECR, IGF2 and c13orf16 were associated with significant increases in gene expression in the post-exercise period in energy balance compared with energy deficit. Furthermore, histone deacetylase, HDAC11 was oppositely regulated at the gene expression level compared with HDAC2, where HDAC11 was hypomethylated yet increased in energy deficit compared with energy balance conditions. Overall, we identify some novel epigenetically regulated genes associated with train-low sleep-low paradigms.

Project description:During the winter, hibernating mammals undergo extreme changes in physiology which allow them to survive without access to food. These animals enter a state of torpor, which is characterized by a decreased metabolism, near-freezing body temperatures, and a dramatically reduced heart rate. The neurochemical basis of this regulation is largely unknown. Based on prior evidence suggesting that the peptide-rich hypothalamus plays critical roles in hibernation, we hypothesized that changes in specific cell-cell signaling peptides (neuropeptides and peptide hormones) underlie physiological changes during torpor/arousal cycles. To test this hypothesis, we used a mass spectrometry-based peptidomics approach to examine seasonal changes of endogenous peptides that occur in the hypothalamus and pituitary of a model hibernating mammal, the thirteen-lined ground squirrel (Ictidomys tridecemlineatus). In the pituitary, we observed changes in a number of distinct peptide hormones as animals prepare for torpor in October, exit torpor in March, and progress from Spring (March) to Fall (August). In the hypothalamus, we observed an overall increase in neuropeptides in October (pre-torpor), a decrease as the animal enters torpor, and an increase in a subset of neuropeptides during normothermic interbout arousals. Notable changes were observed for feeding regulatory peptides from NPY and proSAAS prohormones, opioid peptides from PENK, PDYN, and POMC prohormones, and a number of peptides without well-established functions. In contrast to transcriptome and antibody-based measurements, our mass spectrometry-based approach allowed the identification and measurement of the final processed forms of these peptides after extensive post-translational modifications. Overall, our study provides critical insight into changes in endogenous peptides in the hypothalamus and pituitary during mammalian hibernation that were not available from transcriptome measurements. Understanding the molecular basis underlying the hibernation phenotype may pave the way for future efforts to employ hibernation-like strategies for organ preservation, combating obesity, and treatments for stroke.
