A 3D printed plastic frame deeply impacts yeast cell growth

Project description:Solid State Fermentation (SSF) processes have been explored for yeast growth and protein and metabolites production. However, most of these processes lack standardization. In this work, we present a polylactic acid (PLA) 3D printed matrix that dramatically enhances yeast growth when embedded in liquid media compared to equivalent static cultures, and changes yeast expression patterns at the proteome level. Moreover, differences in sugar assimilation and ethanol production, as the main product of alcoholic fermentation, are observed. Our results suggest that these matrixes may be useful for a vast range of biotechnological applications based on yeast fermentation.

Proteomic and pathway profiling of four Breast Cancer cell lines.

Project description:Biomarker discovery in breast cancer (BC) is a clinical need for therapeutics and non-invasive diagnostics. In a single study, we provide a comparative differential proteomic profile of four invasion, metastasis, angiogenesis and drug resistance. Exosome proteome profile reflects their different BC cell origin suggesting potential indicators of BC subtype. Further, our pathway inference analysis reveals a differential role of exosomes in BC signalling pathways in recipient cells, according to their protein cargo and cell origin. Our results may significantly contribute to further studies for the design of BC biomarker predictor to stratify BC patients and the development of novel therapeutic strategies.BC cell lines and their derived- exosomes, representative of the most relevant BC subtypes in clinic. Differentially-expressed proteins, in both cells and exosomes, include indicators of

The extracellular vesicles of the helminth pathogen, Fasciola hepatica: biogenesis pathways and cargo molecules involved in parasite pathogenesis

Project description:We reveal that whilst the molecular “machinery” required for EV biogenesis is constitutively expressed across the intra-mammalian development stages of the parasite, the cargo molecules packaged within the EVs are regulated, most likely to facilitate the parasites migration through host tissue and to counteract host immune attack.

Dietary effect on the proteome of the common octopus (Octopus vulgaris) paralarvae, LC-MS/MS data

Project description:Nowadays, the common octopus (Octopus vulgaris) culture is hampered by massive mortalities occurring during early life-cycle stages (paralarvae). Despite the causes of the high paralarvae mortality are not yet well defined and understood, the nutritional stress caused by inadequate diets is pointed out as one of the main factors. In this study the effects of diet on paralarvae is analyzed through a proteomic approach, to search for novel biomarkers of nutritional stress. A total of 43 proteins showing differential expression in the different conditions studied have been identified. The analysis highlights proteins related with the carbohydrate metabolism: glyceraldehyde-3-phosphate-dedydrogenase (GAPDH), triosephosphate isomerase; other ways of energetic metabolism: NADP+-specific isocitrate dehydrogenase, arginine kinase; detoxification: glutathione-S-transferase (GST); stress: heat shock proteins (HSP70); structural constituent of eye lens: S-crystallin 3; and cytoskeleton: actin, actin-beta/gamma1, beta actin. These results allow defining characteristic proteomes of paralarvae depending on the diet; as well as the use of several of these proteins as novel biomarkers to evaluate their welfare linked to nutritional stress. Notably, the changes of proteins like S-crystallin 3, arginine kinase and NAD+ specific isocitrate dehydrogenase, may be related to fed versus starving paralarvae, particularly in the first 4 days of development.

Vitrification of embryos modifies foetal placenta proteome. LCMSMS

Project description:Very limited information about the post-implantatory effects of vitrification has been published till now. In a previous study, we observed that vitrification procedure introduced transcriptomic and proteomic modifications in the rabbit foetal placenta at the middle of gestation. In addition, a reduction in maternal placenta and foetal weight was also detected. In order to know if these alterations were temporary or not, the aim of the current study was to analyse the proteomic profile of rabbit foetal placenta at two different times of gestation: Day 14 and Day 24. We performed a comparative 2D-DIGE analysis and found that placentas from vitrified embryos expressed eleven different proteins at Day 14 and thirteen at Day 24. The alteration of serum albumin, isocitrate dehydrogenase 1 [NADP+] and phosphoglycerate mutase 1 were maintained both Day 14 and Day 24. Our results demonstrate that vitrification is not neutral, and induce a substantial alteration of placental protein expression, even at the end of gestation. But, apart from short-term effects observed on embryos, could vitrification entail long-term consequences in those foetuses that are going to be born? Further studies will determine if alterations observed could be the set point of future modifications to manifest into adulthood

Exhaled breath condensate biomarkers for the early diagnosis of lung cancer using proteomics

Project description:The present study explored whether the proteomic analysis of exhaled breath condensate (EBC) may provide potential biomarkers for their use in non-invasive screening strategies for the early detection of lung cancer (LC). EBC was collected from 192 individuals (49 control volunteers, 49 risk factor-smoking volunteers, 46 chronic obstructive pulmonary disease patients and 48 LC patients). Using LC-MS/MS a total of 348 different proteins with a different pattern among the four groups were identified in EBC samples. Despite the great variability observed among individuals, significantly more proteins were identified in the EBC from LC patients compared to other groups. Furthermore, the average number of proteins identified per sample was significantly higher in LC patients and Receiver Operating Characteristic curve analysis showed an area under the curve of 0.8, indicating diagnostic value. Proteins frequently detected in EBC, such as dermcidin and hornerin, along with others much less frequently detected, such as hemoglobin and histone isoforms, were identified. Cytokeratins (KRTs) were the most abundant proteins in EBC samples and levels of KRT6A, KRT6B and KRT6C isoforms were significantly higher in samples from LC patients. Moreover, the amount of most KRTs in EBC samples from LC patients showed a significant positive correlation with tumor size. Finally, we used a random forest algorithm to generate a robust model using EBC protein data for the diagnosis of patients with LC. Thus, this study demonstrates that the proteomic analysis of EBC samples is an appropriated approach to develop biomarkers for the diagnosis of lung cancer.

Comparative endometrial proteomics among fertile women, intrauterine device carriers, and recurrent implantation failure patients using iTRAQ methodology

Project description:Endometrial receptivity is imperative to achieving pregnancy in humans. A disruption in the development of endometrial receptivity is responsible for recurrent implantation failures (RIF) of endometrial origin. To further understand the molecular mechanisms behind the endometrial receptivity process, we used the 8-plex isobaric tag for relative and absolute quantitation (iTRAQ) method to compare and quantify the proteomes from endometrial biopsies of three different endometrial statuses (fertile women, IUD carriers and RIF patients). Overall, iTRAQ allowed to identify 1,889 non-redundant proteins. Of these, 188 were differentially expressed proteins (DEP) (p-value < 0.05) among the three endometrial groups. Pairwise comparisons revealed 133 significant DEP in fertile vs. IUD carriers and 158 DEP in RIF vs. IUD carriers. However, no DEP were identified between fertile and RIF patients. Western blot validation of three DEP involved in endometrial receptivity (Plastin 2, Lactotrasferrin, and Lysozyme) confirmed our iTRAQ results. Moreover, functional KEGG enrichment revealed that complement and coagulation cascades and peroxisome were the two most significant pathways for the RIF vs. IUD comparison and ribosome and spliceosome for the fertile vs. IUD comparison, as possible important pathways involved in the endometrial receptivity acquisition. Our findings confirm that an IUD introduces numerous changes in the endometrial protein profile when compared to fertile and RIF endometria, revealing some key proteins involved in endometrial receptivity. The lack of DEP between fertile and RIF patient endometria suggest either that idiopathic RIF may not have an endometrial origin, with other as-yet-unknown factors involved.

Evaluation by re-derivation of a paternal line after 18th generations on seminal traits, proteome and fertility: Seminal Plasma Spectral Library

Project description:Breeding schemes for meat production in rabbits involved a three-way cross of specialized lines in which a paternal line inseminates maternal crossbred females. Paternal line or terminal sire are selected for growth traits, being the males used for the production of fertile dose at the insemination centres and farms. So high growth rate males must produce, in addition, semen in sufficient quantity and quality to meet the demand of insemination and, nevertheless, several studies have been showed that selection for growth have effects on reproduction performance in female and males. In rabbits, negative effects has been observed in ovulation induction, prenatal survival and genetic correlation to fertility. Many factors influence the production and quality of rabbit semen, management as collection frequency, environment (season or photoperiod, nutrition and genetic. Most of the previous studies have been focused in the effects of selection on the seminal and sperm parameters but, little attention has been paid to the protein seminal plasma or sperm composition and if these changes could be affect the fertility of seminal doses obtained from the paternal males. The aim of this study was to evaluate if selection program by daily gain in fattening period has changed seminal traits, plasma and sperm proteoma and, the fertility of semen when it is used in artificial insemination. To do this we uses two re-derived groups of paternal males obtained from vitrified embryos with a difference of 18 generations between both groups.
