Abstract
The purpose of this study was to examine STC-1's structure, function, and differential expression in large and miniature pigs. We cloned the Hezuo pig's coding sequence, compared its homology, and used bioinformatics to assess the structure. RT-qPCR and Western blot were used to detect the expression in ten tissues of Hezuo pig and Landrace pig. The results showed that Hezuo pig was most closely related to Capra hircus and most distantly related to Danio rerio. The protein STC-1 has a signal peptide and its secondary structure is dominated by the alpha helix. The mRNA expression in the spleen, duodenum, jejunum, and stomach of Hezuo pigs was higher than that of Landrace pigs. And except for heart and duodenum, expression of the protein in Hezuo pig was higher than in another. In conclusion, STC-1 is highly conserved among different breeds of pigs, and the expression and distribution of its mRNA and protein are different in large and miniature pigs. This work can lay the foundation for future study into the mechanism of action of STC-1 in Hezuo pigs and the enhancement of breeding in miniature pigs.

Human Ovarian Granulosa Cells Isolated during an IVF Procedure Exhibit Differential Expression of Genes Regulating Cell Division and Mitotic Spindle Formation. J Clin Med 2019; 8:jcm8122026. [PMID: 31756998 PMCID: PMC6947147 DOI: 10.3390/jcm8122026] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/12/2019] [Revised: 11/13/2019] [Accepted: 11/15/2019] [Indexed: 12/21/2022] Open
Abstract
Granulosa cells (GCs) are a population of somatic cells whose role after ovulation is progesterone production. GCs were collected from patients undergoing controlled ovarian stimulation during an in vitro fertilization procedure, and they were maintained for 1, 7, 15, and 30 days of in vitro primary culture before collection for further gene expression analysis. A study of genes involved in the biological processes of interest was carried out using expression microarrays. To validate the obtained results, Reverse Transcription quantitative Polymerase Chain Reaction (RT-qPCR) was performed. The direction of changes in the expression of the selected genes was confirmed in most of the examples. Six ontological groups ("cell cycle arrest", "cell cycle process", "mitotic spindle organization", "mitotic spindle assembly checkpoint", "mitotic spindle assembly", and "mitotic spindle checkpoint") were analyzed in this study. The results of the microarrays obtained by us allowed us to identify two groups of genes whose expressions were the most upregulated (FAM64A, ANLN, TOP2A, CTGF, CEP55, BIRC5, PRC1, DLGAP5, GAS6, and NDRG1) and the most downregulated (EREG, PID1, INHA, RHOU, CXCL8, SEPT6, EPGN, RDX, WNT5A, and EZH2) during the culture. The cellular ultrastructure showed the presence of structures characteristic of mitotic cell division: a centrosome surrounded by a pericentric matrix, a microtubule system, and a mitotic spindle connected to chromosomes. The main goal of the study was to identify the genes involved in mitotic division and to identify the cellular ultrastructure of GCs in a long-term in vitro culture. All of the genes in these groups were subjected to downstream analysis, and their function and relation to the ovarian environment are discussed. The obtained results suggest that long-term in vitro cultivation of GCs may lead to their differentiation toward another cell type, including cells with cancer-like characteristics.

Transcriptomic Pattern of Genes Regulating Protein Response and Status of Mitochondrial Activity Are Related to Oocyte Maturational Competence-A Transcriptomic Study. Int J Mol Sci 2019; 20:ijms20092238. [PMID: 31067669 PMCID: PMC6539048 DOI: 10.3390/ijms20092238] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/27/2019] [Revised: 04/30/2019] [Accepted: 05/03/2019] [Indexed: 01/22/2023] Open
Abstract
This paper aims to identify and describe new genetic markers involved in the processes of protein expression and modification reflected in the change of mitochondrial activity before and after in vitro maturation of the oocyte. Porcine oocytes collected from the ovaries of slaughtered landrace gilts were subjected to the process of in vitro maturation. Transcriptomic changes in the expression profile of oocyte genes involved in response to hypoxia, the transmembrane protein receptor serine threonine kinase signaling pathway, the “transforming growth factor β receptor signaling pathway”, “response to protein stimulus”, and “response to organic substance” were investigated using microarrays. The expression values of these genes in oocytes was analyzed before (immature) and after (mature) in vitro maturation, with significant differences found. All the significantly altered genes showed downregulation after the maturation process. The most changed genes from these gene ontologies, FOS, ID2, VEGFA, BTG2, CYR61, ESR1, AR, TACR3, CCND2, CHRDL1, were chosen to be further validated, described and related to the literature. Additionally, the mitochondrial activity of the analyzed oocytes was measured using specific dyes. We found that the mitochondrial activity was higher before the maturation process. The analysis of these results and the available literature provides a novel insight on the processes that occur during in vitro oocyte maturation. While this knowledge may prove to be useful in further research of the procedures commonly associated with in vitro fertilization procedures, it serves mostly as a basic reference for further proteomic, in vivo, and clinical studies that are necessary to translate it into practical applications.

Abstract
The growth and development of oocyte affect the functional activities of the surrounding somatic cells. These cells are regulated by various types of hormones, proteins, metabolites, and regulatory molecules through gap communication, ultimately leading to the development and maturation of oocytes. The close association between somatic cells and oocytes, which together form the cumulus-oocyte complexes (COCs), and their bi-directional communication are crucial for the acquisition of developmental competences by the oocyte. In this study, oocytes were extracted from the ovaries obtained from crossbred landrace gilts and subjected to in vitro maturation. RNA isolated from those oocytes was used for the subsequent microarray analysis. The data obtained shows, for the first time, variable levels of gene expression (fold changes higher than |2| and adjusted p-value < 0.05) belonging to four ontological groups: regulation of cell proliferation (GO:0042127), regulation of cell migration (GO:0030334), and regulation of programmed cell death (GO:0043067) that can be used together as proliferation, migration or apoptosis markers. We have identified several genes of porcine oocytes (ID2, VEGFA, BTG2, ESR1, CCND2, EDNRA, ANGPTL4, TGFBR3, GJA1, LAMA2, KIT, TPM1, VCP, GRID2, MEF2C, RPS3A, PLD1, BTG3, CD47, MITF), whose expression after in vitro maturation (IVM) is downregulated with different degrees. Our results may be helpful in further elucidating the molecular basis and functional significance of a number of gene markers associated with the processes of migration, proliferation and angiogenesis occurring in COCs.

Abstract
Abstract
The efficiency of the process of obtaining mature oocytes, and then of porcine embryos in vitro depends on many factors and requires meeting many conditions. These include selection of morphologically appropriate oocytes, selection of appropriate medium components, as well as a number of abiotic factors (appropriate microenvironment during in vitro culture).
Oocytes were taken from 45 pubertal crossbred Landrace gilts. The BCB test was carried out. BCB + oocytes were divided into two groups: “before IVM” and “after IVM”. “Before IVM” oocytes were subjected to molecular analyzes immediately after collection, while “after IVM” oocytes underwent in vitro maturation and then the second BCB test. Oocytes that remained BCB+ after the second test were used for molecular analyzes using Affymetrix expression microarrays.
A group of genes responsible for response to organic substance and response to abiotic stimulus, which underwent significant changes (decrease) was discovered after oocyte in vitro maturation. Genes such as MM, PLDP, SERPINH, MYOF, DHX9, HSPA5, VCP, KIT, SERPINH1, PLD1, and VCP showed the largest decrease after the culture period. The levels of these genes were therefore elevated in oocytes before the in vitro maturation process.
In conclusion, a number of organic and abiotic factors have an impact on the process of the oocyte in vitro maturation. The presented results confirm the literature data in which the low efficiency of obtaining mature oocytes in in vitro conditions is mentioned, which further impacts the amount of viable embryos obtained.

Expression Changes in Fatty acid Metabolic Processrelated Genes in Porcine Oocytes During in Vitro Maturation. ACTA ACUST UNITED AC 2018.

Abstract
Abstract
Mammalian oocytes undergo compound processes of nuclear and cytoplasmic maturation that allow them to reach MII stage. Only fully mature, oocyte can be successfully fertilized by a single spermatozoon. Fatty acids, apart from their role in cellular metabolism, inflammation and tissue development, have positive and detrimental effects on oocyte maturation, fertilization, blastocyst cleavage rate and embryo development in mammals. Using microarrays, we have analyzed the expression changes in fatty acids- -related genes during in vitro maturation of porcine oocytes. The oocytes were recovered from ovaries of 45 pubertal crossbred Landrace gilts and subsequently subjected to BCB test. For further analyses, only granulosa cell-free BCB+ oocytes were used and divided into two groups. The first one, described as “before IVM”, was directly exposed to molecular assays, the second one, described as “after IVM”, was first in vitro matured and then subjected to a second BCB test. Oocytes, if classified as BCB+, were then passed to corresponding molecular analyses. We found significant down-regulation of genes involved in fatty acid metabolic process, such as: ACSL6, EPHX2, FADS2, PTGES, TPI1, TBXAS1, NDUFAB1, MIF, ACADSB and DECR1 in porcine oocytes analyzed after IVM, in comparison to those analyzed before IVM. In conclusion, apart from poor data available concerning analyzed genes in relation to reproductive events, significant changes in their expression point to their potential role as an oocyte developmental competence markers in pigs. Introducing molecular diagnostics of oocytes could be the prospective tool for selection of best gametes, leading to improved outcomes of in vitro fertilization.

Significant Down-Regulation of "Biological Adhesion" Genes in Porcine Oocytes after IVM. Int J Mol Sci 2017; 18:ijms18122685.

Abstract
Proper maturation of the mammalian oocyte is a compound processes determining successful monospermic fertilization, however the number of fully mature porcine oocytes is still unsatisfactory. Since oocytes’ maturation and fertilization involve cellular adhesion and membranous contact, the aim was to investigate cell adhesion ontology group in porcine oocytes. The oocytes were collected from ovaries of 45 pubertal crossbred Landrace gilts and subjected to two BCB tests. After the first test, only granulosa cell-free BCB+ oocytes were directly exposed to microarray assays and RT-qPCR (“before IVM” group), or first in vitro matured and then if classified as BCB+ passed to molecular analyses (“after IVM” group). As a result, we have discovered substantial down-regulation of genes involved in adhesion processes, such as: organization of actin cytoskeleton, migration, proliferation, differentiation, apoptosis, survival or angiogenesis in porcine oocytes after IVM, compared to oocytes analyzed before IVM. In conclusion, we found that biological adhesion may be recognized as the process involved in porcine oocytes’ successful IVM. Down-regulation of genes included in this ontology group in immature oocytes after IVM points to their unique function in oocyte’s achievement of fully mature stages. Thus, results indicated new molecular markers involved in porcine oocyte IVM, displaying essential roles in biological adhesion processes.
