Project description:Skin aging is one of the hallmarks of the aging process that causes physiological and morpho-logical changes. Recently, several nutritional studies were conducted to delay or suppress the aging process. This study investigated whether nutritional supplementation of the eggshell membrane (ESM) has a beneficial effect on maintaining skin health and improving the skin aging process in interleukin-10 knockout (IL-10 KO) mice. Oral supplementation of 8% powdered-ESM (pESM) upregulated the expression of growth factors, including transforming growth factor β1, platelet-derived growth factor-β and connective tissue growth factor, and suppressed skin thinning.

Project description:Skin aging is one of the hallmarks of the aging process that causes physiological and morpho-logical changes. Recently, several nutritional studies were conducted to delay or suppress the aging process. This study investigated whether nutritional supplementation of the eggshell membrane (ESM) has a beneficial effect on maintaining skin health and improving the skin ag-ing process using neonatal normal human epidermal keratinocytes (NHEK-Neo). 1 mg/mL of enzymatically hydrolyzed ESM (eESM) upregulated the expression of keratinocyte differentiation markers, including keratin 1, filaggrin and involucrin, and changed the keratinocyte morphology.

Project description:The effect of krill powder, a mixed source of protein and n-3 PUFAs from Antarctic Krill (Euphausia superba), on hepatic gene expression was analyzed in CBA/J mice. Mice were fed a low-fat control diet or a 3% (w/w) krill powder low-fat diet for three months. Gene expression profiling on liver samples revealed that the krill powder supplemented diet modulated a large number of pathways compared to the control diet, and we focused on the genes involved in metabolic processes. Pathways involved β-oxidation, glucose metabolism, and amino acid catabolism were downregulated. In contrast, genes involved in the mitochondrial electron transport chain were upregulated. Thus, a krill powder supplemented diet had potent and specific effects on energy metabolism and oxidative phosphorylation at the gene level. This indicates that krill powder supplementation could be an approach to prevent age-related decline in mitochondrial respiratory chain function and weight loss.

Project description:Milk-derived peptides and milk fat globule membrane (MFGM) have gained interest as health-promoting food ingredients. However, the mechanisms by which these nutraceuticals modulate the function of biological systems often remain unclear. We utilized Caenorhabditis elegans to elucidate how milk-derived Protein powders rich in MFGM, previously used in a clinical trial, affect the physiology of this model organism. Our results demonstrate that Protein powders do not affect lifespan but promote the fitness of the animals. Surprisingly, gene expression analysis revealed that Protein powders decrease the expression of genes functioning on innate immunity, which also translates into reduced survival on pathogenic bacteria. One of the innate immunity-associated genes showing reduced expression upon Protein powder supplementation is cpr-3, the homolog of human cathepsin B. Interestingly, knockdown of cpr-3 enhances fitness, but not in Protein powder-treated animals, suggesting that protein powders contribute to fitness by downregulating the expression of this gene. In summary, this research highlights the value of C. elegans in testing the biological activity of food supplements and nutraceuticals. Furthermore, this study should encourage investigations into whether milk-derived peptides and MFGM mediate their beneficial effects through the modulation of cathepsin B expression in humans.

Project description:The egg production cycle of broiler breeder hens is comparatively shorter than laying hens, and as they age, their egg production and eggshell quality decline. The eggshell formation occurs in the shell glands, which are influenced by several factors, including aging. The objectives of the study were to 1) identify differentially expressed genes (DEGs) and biological pathways in the shell glands (young vs aged) and 2) determine the age-associated changes in eggshell quality. The shell glands tissues were collected from broiler breeder hens at peak-lay (35 weeks of age; termed as “young”) and late-lay phases (50 weeks of age; termed as “aged”) (n=30/group) at 10-15 hours post-ovulation (unclassified egg present in the shell glands). To delineate the genes and biological pathways associated with eggshell biomineralization, total RNAs extracted from the shell glands of young and aged hens (n=6/group) were analyzed using RNA sequencing and validated using real-time PCR. The ultrastructure quality of eggshells (n=10 eggs/group) was analyzed using a Scanning Electron Microscope (SEM), and the elemental composition of eggshells was measured using SEM-Energy Dispersive Spectrometry, and their variability was confirmed by t-test in RStudio. Eggshell strength, thickness, palisade layer, and mammillary width were significantly higher in the young, while mammillary knobs were wider in aged hens (p<0.05). The sulfur and potassium levels in eggshells were higher in young hens than aged ones. Although the young group had a higher calcium concentration in the eggshells, the difference was statistically insignificant (p>0.05). RNA-Seq data identified highly upregulated genes specific to eggshell biomineralization, such as SPP1 (binds to hydroxyapatite), OTOP2 (maintains high conc. of cytosolic Ca2+), PKD2 (helps in releasing Ca2+), SLC22A15 (transports organic ions), and STAB2 (binds to gram-positive and gram-negative bacteria). The DEGs showed significant enrichment for biological pathways (SLC6A6, KCNK7, UCP3, SCNN1A, PKD2, OTOP2) associated with the transport of monoatomic and inorganic cations across the cell membrane, molecular functions related to the transport of potassium ions and the activity of monoatomic cation channels (KCNK7, PKD2, OTOP2), and the cellular components involved in the luminal side of the endoplasmic reticulum membrane (CALR, PKD2). These findings suggest that the aging process downregulates the transcriptomes of the shell glands, negatively impacting the transportation of ions required for eggshell formation, resulting in poor eggshell quality.

Project description:Eggshell (ES) and eggshell membrane (ESM) is a significant byproduct of the egg producing industry (Ahmed et al., 2019). Many studies have been undertaken to utilize ES waste for potential value added applications (Cordeiro and Hincke, 2011). Described here are the datasets from our evaluation of processed eggshell membrane powder (PEP) as a wound healing product using the mouse excisional wound splinting model (Ahmed et al., 2019). PEP biomaterial was characterized by proteomics using various extraction and solubilization strategies including moderate (lithium dodecyl sulphate (LDS) and urea/ammonium bicarbonate) and harsh conditions (3-mercaptopropionic acid (3-MPA) and NaOH/dimethylsulfoxide) in order to progressively overcome its stable, insoluble nature (Ahmed et al., 2019, Ahmed et al., 2017). Analysis of proteomic data allowed the relative abundance of the main PEP protein constituents to be determined. The efficacy of PEP for promotion of wound healing was assessed using the mouse excisional wound splinting model, and well-established semi-quantitative histological scoring. (More details about the PEP biomaterial characterization and its in vivo evaluation can be found in the related research article (Ahmed et al., 2019)).
