Transcriptomic profile of porcine corpus luteum after PPAR gamma ligands treatment

Project description:The corpus luteum plays a critical role in reproduction because it is the primary source of circulating progesterone. This study aimed to determine the in vitro effect of peroxisome proliferator-activated receptor gamma (PPARγ) ligands on the transcriptome genes expression in the porcine corpus luteum in the mid- and late-luteal phase of the estrous cycle using RNA-seq technology. The corpus luteum slices were incubated in vitro in the presence of PPARγ agonist – pioglitazone and antagonist—T0070907. We identified 40 differentially expressed genes after pioglitazone treatment and 40 after T0070907 treatment in the mid-luteal phase as well as 26 after pioglitazone and 29 after T0070907 treatment in late-luteal phase of the estrous cycle. In addition, we detected differences in genes expression between the mid- and late-luteal phase without treatment (409). These results should become a basis for further studies explaining the mechanism of PPARγ action in the reproductive system in pigs.

Expression data from early luteal bovine endometrium

Project description:In both beef and dairy cattle, the majority of embryo loss occurs in the first 14 days following insemination. During this period, the embryo is completely dependent on its maternal uterine environment for development, growth and ultimately survival, therefore an optimum uterine environment is critical to embryo survival. We used microarrays to assess endometrial gene expression in high and low fertility heifers during the mid-luteal phase of the estrous cycle. Charlaois × Limousin heifers were artificially inseminated on 4 successive occasions and heifers were subsequently characterized as either high or low fertility (HF; LF) based on the presence of an embryo on day 28 of pregnancy on all four inseminations or on one occasion only, respectively. From this population of animals, HF and LF heifers were slaughtered on day 7 of a synchronized estrous cycle and global gene expression in uterine endometrial tissue was determined using the Affymetrix 23K Bovine GeneChip.

VISFATIN (NAMPT) AFFECTS GLOBAL GENE EXPRESSION IN PORCINE ANTERIOR PITUITARY CELLS DURING THE MID-LUTEAL PHASE OF THE OESTROUS CYCLE

Project description:Pituitary belongs to a most important endocrine glands which takes part in the regulation of reproductive functions. The proper functioning of this intermediary between the central nervous system and the target tissues of the reproductive system ensures the proper course of the estrous cycle and affects the female's reproductive potential. It is believed that visfatin, a hormone belonging to the adipokine family, may be responsible for the control of reproductive functions in response to the actual metabolic state of female. Herein we verified hypothesis assuming the modulatory effect of visfatin on the anterior pituitary transcriptome during the mid-luteal phase of the oestrous cycle. We analyzed samples obtained from 5 individuals (n=5). After the enzymatic tissue digestion with the use collagenase V and pancreatin cells were divided for two groups: controls [without treatment] and visfatin (100 ng/mL) treated ones. In vitro cell cultures were conducted for 24 hours.

Expression data from late-luteal bovine endometrium

Project description:In both beef and dairy cattle, the majority of embryo loss occurs in the first 14-16 days following insemination. During this period, the embryo is completely dependent on its maternal uterine environment for development, growth and ultimately survival, therefore an optimum uterine environment is critical to embryo survival. We used microarrays to assess endometrial gene expression in high and low fertility heifers during the late-luteal phase of the estrous cycle.

Chemerin Impact on Alternative mRNA Transcription in the Porcine Luteal Cells.

Project description:Chemerin participates in the regulation of processes related to physiological and disorder mechanisms in mammals, including metabolism, obesity, inflammation, and reproduction. In this study, we have investigated chemerin influence on alternative mRNA transcription within the porcine luteal cell transcriptome, such as differential expression of long non-coding RNAs (DELs) and their interactions with differentially expressed genes (DEGs), differences in alternative splicing of transcripts (DASs), and allele-specific expression (ASEs) related to the single nucleotide variants (SNVs) frequency. Luteal cells were collected from gilts during the mid-luteal phase of the oestrous cycle. After in vitro culture of cells un-/treated with chemerin, the total RNA was isolated and sequenced using the high-throughput method. The in silico analyses revealed 24 DELs cis interacting with 6 DEGs and trans-correlated with 300 DEGs, 137 DASs events, and 18 ASEs. The results enabled us to analyse metabolic and signalling pathways in detail, providing new insights into the effects of chemerin on the corpus luteum functions related to inflammatory response, leukocyte infiltration, the occurrence of luteotropic and luteolytic signals (leading to apoptosis and/or necroptosis). Validation of the results using qPCR confirmed the predicted expression changes. Chemerin at physiological concentrations significantly modifies the transcription processes in the porcine luteal cells.

Chemerin inhibits cancer progression by impairing the maturation of neovessels

Project description:Chemerin is a leukocyte chemoattractant and an adipokine. Overexpression of chemerin by tumor cells or the host inhibits tumor progression in different mouse models, through a mechanism involving the chemerin receptor CMKLR1 and impairment of endothelial cell/pericyte interactions in neovessels.
