Abstract
During preimplantational embryo development, PI3K/AKT regulates cell proliferation and differentiation and nobiletin modulates this pathway to promote cell survival. Therefore, we aimed to establish whether, when the AKT cascade is inhibited using inhibitors III and IV, nobiletin supplementation to in vitro culture media during the minor (2 to 8-cell stage, MNEGA) or major (8 to 16-cell stage, MJEGA) phases of EGA is able to modulate the development and quality of bovine embryos. In vitro zygotes were cultured during MNEGA or MJEGA phase in SOF + 5% FCS or supplemented with: 15 μM AKT-InhIII; 10 μM AKT-InhIV; 10 μM nobiletin; nobiletin+AKT-InhIII; nobiletin+AKT-InhIV; 0.03% DMSO. Embryo development was lower in treatments with AKT inhibitors, while combination of nobiletin with AKT inhibitors was able to recover their adverse developmental effect and also increase blastocyst cell number. The mRNA abundance of GPX1, NFE2L2, and POU5F1 was partially increased in 8- and 16-cell embryos from nobiletin with AKT inhibitors. Besides, nobiletin increased the p-rpS6 level whether or not AKT inhibitors were present. In conclusion, nobiletin promotes bovine embryo development and quality and partially recovers the adverse developmental effect of AKT inhibitors which infers that nobiletin probably uses another signalling cascade that PI3K/AKT during early embryo development in bovine.

Abstract
During embryo development the embryonic genome activation (EGA) is one of the most important events and in bovine embryos it occurs at the 8- to 16-cell stage. Invitro embryo production increases the levels of reactive oxygen species (ROS), which leads to the low quality of the produced blastocysts, possibly by affecting EGA. Nobiletin is an antioxidant that affects cell cycle regulation (Huang et al. 2016 Evid. Based. Complement. Alternat. Med. 2016, 2918796, https://doi.org/10.1155/2016/2918796). Therefore, we aimed to evaluate the effect of nobiletin supplementation, in two key periods of early embryo development, on blastocyst yield and expression of selected genes of the ERK1/2 pathway and oxidative stress on produced embryos. Invitro zygotes were cultured in synthetic oviductal fluid (SOF) with 5% fetal calf serum (control, C); C with 5 or 10µM nobiletin (MedChemExpress) (N5, N10); or C with 0.03% dimethyl sulfoxide (CDMSO; vehicle for nobiletin dilution) during the minor (21–54h post-insemination (hpi): 2- to 8-cell; MNEGA; 12 replicates) or major (54–96 hpi: 8- to 16-cell; MJEGA; 10 replicates) phase of EGA. The speed of development was considered and embryos that reached ≥8 cells at 54 hpi from MNEGA phase and ≥16 cells at 96 hpi from MJEGA phase, were selected and further cultured in control medium until Day 7. Embryos at ≥8 cell (MNEGA), ≥16 cell (MJEGA) stage, and Day 7 blastocysts from both periods were snap-frozen in liquid N2 for gene expression analysis (3 pools of 10 embryos/treatment). The expression of genes related to ERK1/2 pathway (H3–3B, H3–3A, NFE2L2) and oxidative stress (GPX1) were measured by quantitative PCR; H2AFZ and ACTB were used as housekeeping genes. Statistical analysis was assessed by one-way ANOVA. At 54 hpi, irrespective of nobiletin supplementation, no differences were found in the proportion of embryos that reached the 8-cell stage between groups in both phases (≈60%). At 96 hpi, nobiletin during MJEGA showed a higher proportion of embryos reaching the 16-cell stage than control groups (≈70% vs. ≈60%, respectively; P<0.001). Blastocyst yield for MNEGA and MJEGA was higher (P<0.001) for N5 (40.0±0.8% and 46.7±0.8%) and N10 (41.0±0.9% and 54.5±1.1%) compared with C (32.0±0.6% and 38.4±1.1%) and CDMSO (31.2±0.4% and 35.8±1.0%) groups, while N10 was higher (P<0.05) compared to N5 group in MJEGA. The expression of H3–3B and H3–3A were higher (P<0.05) in 8-cell embryos from N5 and N10 groups during MNEGA; while in 16-cell embryos, H3–3B and NFE2L2 were higher (P<0.05) only in the N10 group compared with both controls during MJEGA. GPX1 was upregulated in nobiletin-supplemented groups from both phases (8- and 16-cell embryos and blastocysts) compared with controls (P<0.05). In conclusion, nobiletin supplementation during minor or major EGA has a positive effect in pre-implantation embryo development and modifies the transcription of cell cycle and oxidative stress genes in early embryos. These benefits can be attributed to its bioactivity and indicate that it might be a tool to overcome EGA and ROS disorders in bovine invitro-produced embryos.This research was funded by MINECO-Spain AGL2015-70140-R, PID2019-111641RB-I00, RTI2018-093548-B-I00; SENESCYT-Ecuador; FAPESP-Brazil 2017/20339-3, CNPq-Brazil 304276/2018-9.

Abstract
The aims of this study were (i) to investigate changes in the global transcriptome of bovine endometrial explants induced by exposure to blastocysts, (ii) to investigate if male and female blastocysts elicit a differential response in the endometrial transcriptome in vitro and (iii) to determine whether bovine endometrium responds to the presence of murine embryos. In Experiment 1, endometrial explants from the same uterus were cultured for 6 h with or without 20 in vitro-produced bovine blastocysts. In Experiment 2, endometrial explants were cultured with male or female bovine blastocysts produced in vitro by IVF either using sex-sorted semen or conventional unsorted semen followed by embryo sexing based on a biopsy. In Experiment 3, endometrial explants were cultured alone or in the presence of bovine blastocysts (n = 25) or murine blastocysts (n = 25). Following culture, explants were snap frozen and stored at -80°C until RNA extraction, qPCR or RNA-Seq. Culture with bovine blastocysts increased endometrial expression of 40 transcripts, all of which were interferon-tau induced. Culture with male or female bovine blastocysts increased transcript abundance of five classic interferon-stimulated genes (MX1, MX2, ISG15, OASY1, RSAD2) in explants; however, there was no difference in abundance of transcripts previously reported to be related to embryonic sex (IFNAR1, IFNAR2, CTGF, ARTN, SLC2A1, SLC2A5). Exposure to murine blastocysts did not elicit any detectable change in transcript abundance. These findings, coupled with our previous data, indicate that very local, interferon-tau-induced changes in endometrial gene expression occur in response to blastocysts; whether such changes play any role in subsequent pregnancy recognition remains to be established.

Abstract
Embryonic genome activation (EGA) is a critical event in early embryonic development and occurs in 8-16-cell stage embryos in bovine. Invitro embryo production increases reactive oxygen species (ROS), leading to low yield and cell death. Nobiletin is an antioxidant that inhibits ROS production and affects cell cycle regulation. The aim of this study was to evaluate the effect of nobiletin supplementation in two key periods of early embryo development on blastocyst yield and expression of candidate genes of the Akt pathway. Invitro-produced zygotes were cultured in synthetic oviductal fluid supplemented with 5% FCS (control; C); C with 5 or 10 µM nobiletin (MedChemExpress; N5, N10) or C with 0.03% dimethyl sulfoxide (CD vehicle for nobiletin dilution) during the minor (2-8-cell stage; MNEGA) or major (8-16-cell stage; MJEGA) phase of EGA, considered as two separate experiments. For all groups, the speed of development was considered, and normally developing embryos that reach ≥8 cells at 54h post-insemination and ≥16 cells at 96h post-insemination were selected and cultured in control medium until Day 8, respectively. Embryos at ≥8-cell stage (N5/N10 MNEGA), 16-cell stage (N5/N10MJEGA), and Day 7 blastocysts of both periods were snap-frozen in LN2 for gene expression analysis. Cleavage rate and blastocyst yield (Day 7-8) were evaluated. The mRNA abundance of candidate genes related to the Akt pathway (CDK2, PGC1A, PPARG, RPS6KB1) and oxidative stress (GPX1) was measured by quantitative PCR. The H2AFZ and ACTB genes were used as housekeeping genes. Statistical analysis was assessed by one-way ANOVA. Nobiletin supplementation during MNEGA showed no differences in cleavage rate, whereas the blastocyst yield at Day 8 was higher (P<0.001) for N5 (42.9±1.4%) and N10 (45.3±2.1%) compared with C (32.9±1.1%) and CD (32.6±1.4%) groups. When nobiletin was supplemented during MJEGA, no differences were found in cleavage rate; however, Day 8 blastocyst yield was higher (P<0.001) for N10 (61.8±0.7%) compared with C (45.2±1.7%), CD (43.6±1.4%), and N5 (52.1±2.1%) groups, whereas N5 was higher (P<0.05) compared with both control groups. The mRNA abundance of CDK2 significantly increases in 8-cell stage embryos from N5 and N10 groups during MNEGA, whereas 16-cell stage embryos from N10 group during MJEGA showed a significant increase compared with both controls (P<0.05). The expression of PGC1A was significantly higher in blastocysts from N5, N10 during MNEGA, and N10 during MJEGA groups compared with both controls (P<0.05). No differences were observed for PPARG and RPS6KB1 in any group from both phases. GPX1, an oxidative indicator gene, was up-regulated in all nobiletin-supplemented groups from both phases compared with controls (P<0.05). In conclusion, supplementation of embryo culture during MNEGA or MJEGA with nobiletin improves embryo development and induces changes in the transcriptional genes related to cell cycle regulation and oxidative stress. This suggests that nobiletin acts through the Akt pathway during the first stages of embryonic development.

Abstract
One of the problems associated with in vitro production of embryos in bovine is the increase in reactive oxygen species (ROS), which leads to cell alterations and death. Nobiletin is a polymethoxyflavone isolated from citrus fruits with various beneficial effects on cell cycle regulation and inhibition of ROS production. In a preliminary study, we demonstrated that supplementation of 25 or 50 µM nobiletin to the in vitro maturation (IVM) medium reduces oxidative stress and improves oocyte nuclear and cytoplasmic maturation and embryo development. Thus, in this study, we aimed to evaluate the antioxidant activity of nobiletin during IVM on bovine matured oocytes, their cumulus cells (CC), and blastocysts by quantitative changes of gene expression. Immature cumulus oocytes complexes (COC) were aspirated from ovaries of slaughtered heifers. Selected COC underwent IVM in TCM-199+10% FCS and 10ng mL−1 epidermal growth factor (EGF; Control) supplemented with 25 µM (Nob25) or 50 µM (Nob50) nobiletin (MedChemExpress, Monmouth Junction, NJ, USA) or 0.001% dimethyl sulfoxide (DMSO control), a vehicle for nobiletin dilution, in 5% CO2 in air at 38.5°C. After 24h, 50 matured oocytes/group and their CC were snap-frozen in LN2 for gene expression analysis. The remaining oocytes were fertilized (Day 0) and cultured in vitro. Blastocysts (Day 7; n=50/group) were snap-frozen in LN2 for gene expression analysis (5 replicates). The mRNA abundance of candidate genes related with oxidative stress (SOD2, CYP51); apoptosis (BAX); quality (BMP15, BMP7, CLIC1, MAPK1, ABCB1); and cell junction (GJA1) was measured by quantitative PCR; H2AFZ and 18S rRNA were used as housekeeping genes. Statistical significance was assessed by one-way ANOVA. Supplementation of IVM medium with Nob25 or Nob50 produced changes in the expression levels of genes related to oxidative stress and apoptosis during IVM compared with controls. SOD2 and CYP51 were down-regulated in oocytes and CC (P<0.05) but not in blastocysts, whereas BAX was down-regulated only in CC (P<0.05). Nobiletin supplementation in IVM increased the expression of MAPK1 in oocytes and blastocysts (P<0.05); however, no differences were observed in CC. BMP15 for oocytes and their CC and GJA1 for CC were up-regulated in Nob25 and Nob50 groups compared with controls (P<0.05). The relative abundance of CLIC1 decreased in blastocysts from both nobiletin groups compared with controls (P<0.05). No significant differences in the expression in ABCB1 and BMP7 were detected. In conclusion, our results suggest that supplementation of 25 or 50 µM nobiletin to the IVM medium reduces oxidative stress in oocytes and CC, decreases CC apoptosis, and provokes positive changes in the expression of genes related to oocyte and embryo quality.

Abstract
We observed that in vitro transcriptomic response of bovine oviduct epithelial cells (BOEC) to the early embryo could be the result of a contact-dependent signalling effect or interactions with embryo secretions. In order to determine this, BOEC were co-cultured directly with embryos or indirectly with embryo-conditioned media (CM); BOEC from the isthmus of oviducts at early luteal phase were cultured with TCM-199+10% fetal calf serum (FCS) in 4-well plates in 5% CO2 in air at 38.5°C for 6 days until confluence. In vitro 2- and 8-cell embryos as well as their CM were produced in parallel. A day before co-culture, BOEC medium was replaced with SOF+10% FCS. Groups for 2- and 8-cell embryos were established: BOEC in direct contact with embryos; BOEC in the same well as embryos but not in indirect contact; BOEC with embryo CM; and BOEC without embryos, as a control. Polyester mesh was used to maintain embryos position on top of the cells. After 48 h of co-culture, BOEC were recovered for gene expression analysis (4 replicates). The relative abundance of candidate genes previously shown to be affected by the presence of embryo in vivo (Maillo et al. 2015 Biol Reprod. 92, 144) [SMAD6 (BMP signalling pathway); ROCK1, ROCK2 (cytokinesis); SOCS3 (inflammatory response); PRELP (extracellular matrix)] or in vitro (Schmaltz-Panneau et al. 2014 Anim. Reprod. Sci. 149, 103-106) [GPX4, NFE2L2 (oxidative stress); SCN9A (sodium ion binding); EPSTI1 (tissue remodelling); IGFBP3 (insulin-like growth factor binding); TDGF1 (BMP signalling pathway); AGR3 (regulation of ciliary beating)] was assessed by RT-qPCR. H2A.Z and ACTG1 were used as housekeeping genes. Statistical analysis was assessed by ANOVA. The BOEC responded to the presence of 2-cell embryos only when in direct contact by significantly decreasing abundance of NFE2L2. Both direct and indirect embryo contact or culture with CM significantly decreased GPX4, ROCK2, and SCN9A transcripts compared with control. The presence of 2-cell embryos irrespective of being in direct or indirect contact reduced the expression of SMAD6 compared with the control and CM groups. In the case of CM, expression of IGFBP3 was enhanced compared with the control but was similar to the presence of the 2-cell embryos. In the presence of 8-cell embryos, direct contact with BOEC significantly down-regulated the expression for GPX4 and SOCS3, whereas expression of SCN9A was up-regulated. The opposite was observed when compared with control. The presence of 8-cell embryos down-regulated the expression of SMAD6 and ROCK2 compared with the CM group, whereas direct or indirect contact with BOEC or culture with CM down-regulated the expression of PRELP compared to control. In conclusion, these results provide evidence for a differential affect on the transcriptome of BOEC in vitro depending on embryo stage. These changes may be related either with direct embryo contact or embryo secretions released into the media.

Abstract
The presence of a single 8-cell embryo does not alter the transcriptome of the cells of the oviducal isthmus, although a local effect at the precise position of the embryo cannot be ruled out. Thus, we aimed to study the local embryo effect on the transcriptomic response of the epithelial cells of the oviduct in vivo. Fifteen heifers were synchronized and all showed standing heat and were artificially inseminated. All heifers were slaughtered on Day 2.5 after oestrus. The oviducts from 13 animals (with a corpus luteum, CL) were isolated, trimmed free of tissue and divided between ampulla and isthmus. The ipsilateral isthmus was then divided into smaller sections (2 cm). Each section was sequentially flushed until the embryo was located and was then opened and scraped longitudinally to obtain the epithelial cells. Cells were snap-frozen in LN2 for gene expression analysis. All recovered embryos were found at the beginning of the isthmus of the oviduct ipsilateral to the CL. Three at 2-cell stage and 1 at 8-cell stage. The recovery rate was 30.8% (4/13) and only samples from these 4 animals were used for analysis. The 2-cm sections selected for the transcriptomic analysis were embryo section (ES), in which the embryo was found; proximal section (PS), through which the embryo had passed; distal section (DS), on the uterine side of the embryo; and contralateral section (CS), section from the contralateral isthmus. The expression pattern of 10 differentially expressed genes between the isthmus of pregnant and cyclic heifers (Maillo et al. 2015 Biol Reprod. 92, 144) were assessed by RTq-PCR relative to 2 housekeeping genes, H2A.Z and ACTG. Five up-regulated genes (STK32A, SLC26A3, KERA, QRFPR, MCTP1) and 5 down-regulated (SOD3, PRELP, VAT1L, SOCS3, CCL20) were analysed. One-way ANOVA and t-test was used for statistical analysis. Comparison between ES and the CS revealed one significantly altered gene (VAT1L). This is in agreement with our in vivo results in which VAT1L was also down-regulated in the presence of embryos. Comparison within the ipsilateral oviduct of ES and PS samples revealed STK32A, SLC26A3, QRFPR, MCTP1, and SOCS3 transcripts significantly down-regulated compared with DS samples, whereas the expression for CCL20 was different between ES and DS but similar to the PS. In conclusion, the fact that 5 out of 10 transcripts were different between the segment where the embryo was collected and other locations in the oviduct suggests the presence of embryo site-specific signal. However, comparison between the ipsilateral embryo site with the contralateral site revealed that only one transcript was different. Moreover, the similarities in the ipsilateral oviduct between embryo and proximal site may be due to the passage of the embryo. Furthermore, the location of the embryo close to the ampullary-isthmic junction may mask the effect due to the spatial differences of the bovine oviduct.

Abstract
Artemin a member of the glial cell line-derived neurotrophic factor (GDNF) family is present in mice and human preimplantation embryos, and reproductive tract, during early pregnancy promoting embryo development in vitro. The presence of artemin in cattle embryos and reproductive tract, however, is unknown. In the present work we identified for first time artemin in bovine uterine fluid (UF) (Western blot), endometrium (RT-PCR, Western blot and immunohistochemistry) and embryos (RT-PCR and immunohistochemistry) during early preimplantation development. In addition, GFRalpha3, a component of the artemin receptor was localized in blastocysts produced in vitro. Individually developing embryos released ARTEMIN in culture medium and triggered ARTEMIN mRNA down-regulation in epithelial cells from endometrial cell cultures. Our results suggest that ARTEMIN derived from early embryos and maternal reproductive tract may exert important roles during early development in cattle.

Abstract
Endocannabinoids are known to mediate practically all reproductive events in mammals; however, little is known about their role in oocyte maturation. Through RT-PCR and immunocytochemistry, this study confirms the presence of CB1 and CB2 cannabinoid receptors in bovine oocytes and shows how exposure to the exogenous cannabinoids HU-210 and THC during their in vitro maturation (IVM) activates the phosphorylation of AKT and ERK1/2 proteins associated with the resumption of meiosis. Although supplementation with HU-210 or THC during IVM did not increase blastocyst yields, the expression of interferon tau (IFNτ) and gap junction alpha-1 protein (GJA1) was enhanced at the blastocyst stage. Our data suggest that cannabinoid agonists may be useful IVM supplements as their presence during oocyte maturation upregulates the expression in blastocysts of key genes for embryo quality.

Abstract
Cannabinoid receptors are able to couple to different families of G proteins when activated by an agonist drug. It has been suggested that different intracellular responses may be activated depending on the ligand. The goal of the present study was to characterize the pattern of G protein subunit stimulation triggered by three different cannabinoid ligands, Δ9-THC, WIN55212-2, and ACEA in mouse brain cortex. Stimulation of the [35S]GTPγS binding coupled to specific immunoprecipitation with antibodies against different subtypes of G proteins (Gαi1, Gαi2, Gαi3, Gαo, Gαz, Gαs, Gαq/11, and Gα12/13), in the presence of Δ9-THC, WIN55212-2 and ACEA (submaximal concentration 10 μM) was determined by scintillation proximity assay (SPA) technique in mouse cortex of wild type, CB1 knock-out, CB2 knock-out and CB1/CB2 double knock-out mice. Results show that, in mouse brain cortex, cannabinoid agonists are able to significantly stimulate not only the classical inhibitory Gαi/o subunits but also other G subunits like Gαz, Gαq/11, and Gα12/13. Moreover, the specific pattern of G protein subunit activation is different depending on the ligand. In conclusion, our results demonstrate that, in mice brain native tissue, different exogenous cannabinoid ligands are able to selectively activate different inhibitory and non-inhibitory Gα protein subtypes, through the activation of CB1 and/or CB2 receptors. Results of the present study may help to understand the specific molecular pathways involved in the pharmacological effects of cannabinoid-derived drugs.

Abstract
To evaluate the effect of conditioned media (CM) and Extracellular Vesicles (EVs) derived from bovine oviduct epithelial cell (BOEC) lines on the developmental capacity of bovine zygotes and the quality of embryos produced in vitro, presumptive zygotes were cultured under specific conditions. In experiment 1, zygotes were cultured either on monolayers from BOEC extended culture (E), together with fresh BOEC suspension cells, or with BOEC-CM from fresh or E-monolayers. In experiment 2, EVs were isolated from BOEC-CM and characterized (150-200 nm) by Nanosight® and electron microscopy. Zygotes were cultured in the presence of 3x10(5) EVs/mL, 1.5x10(5) EVs/mL or 7.5x10(4) EVs/mL of fresh or frozen BOEC-EVs. In experiment 3, zygotes were cultured in absence of FCS but with EVs from BOEC-E that had been cultured in different culture media. In experiment 4, zygotes were cultured in SOF+5% normal-FCS, or EV-depleted-FCS. In all cases, cleavage rate (Day 2) and blastocyst development (Day 7-9) was assessed. Blastocysts on Days 7/8 were used for quality evaluation through differential cell count, cryotolerance and gene expression patterns. No differences were found among all FCS-containing groups in cleavage rate or blastocyst yield. However, embryos derived from BOEC-CM had more trophectoderm cells, while embryos derived from BOEC-EVs, both fresh and frozen, has more trophectoderm and total cells. More embryos survived vitrification in the BOEC-CM and BOEC-EV groups. In contrast, more embryos survived in the EV-depleted-FCS than in normal-FCS group. Gene expression patterns were modified for PAG1 for embryos cultured with EVs in the presence of FCS and for IFN-T, PLAC8, PAG1, CX43, and GAPDH in the absence of FCS. In conclusion, EVs from FCS have a deleterious effect on embryo quality. BOEC-CM and EVs during in vitro culture had a positive effect on the quality of in vitro produced bovine embryos, suggesting that EVs have functional communication between the oviduct and the embryo in the early stages of development.

Abstract
Offspring telomere length (TL) has been correlated with paternal TL, but the mechanism for this parent of origin-specific inheritance remains unclear. The objective of this study has been to determine the role of spermatozoa TL in embryonic telomere lengthening by using two mouse models showing dimorphism in their spermatozoa TL: Mus musculus vs Mus spretus and old vs young Mus musculus. Mus spretus spermatozoa displayed a shorter TL than Mus musculus. Hybrid offspring exhibited lower TL compared with Mus musculus starting at the two-cell stage, before the onset of telomerase expression. To analyze the role of spermatozoa telomeres in early telomere lengthening, we compared the TL in oocytes, zygotes, two-cell embryos and blastocysts produced by parthenogenesis or by fertilization with Mus musculus or Mus spretus spermatozoa. TL was significantly higher in spermatozoa compared with oocytes, and it increased significantly from the oocyte to the zygote stage in those embryos fertilized with Mus musculus spermatozoa, but not in those fertilized with Mus spretus spermatozoa or produced by parthenogenesis. A further increase was noted from the zygote to the two-cell stage in fertilized Mus musculus embryos, whereas hybrid embryos maintained the oocyte TL. Spermatozoa TL shortened with age in Mus musculus and the offspring from young males showed a significantly higher TL compared with that fathered by old males. These significant differences were already noticeable at the two-cell stage. These results suggest that spermatozoa telomeres act as a guide for telomerase-independent telomere lengthening resulting in differences in TL that persist after birth.

Abstract
The objective of this study was to examine the time during the postfertilization period that gene expression patterns in in vitro-cultured bovine embryos diverge from those of their in vivo-cultured counterparts. Presumptive bovine zygotes were produced by in vitro maturation and fertilization of immature oocytes collected from the ovaries of slaughtered animals. Approximately 20 h post insemination (hpi), zygotes were denuded and randomly divided into two groups for culture either in vitro, in synthetic oviduct fluid medium, or in vivo, in the ewe oviduct. Embryos were recovered from both systems at approximately 30 hpi (2-cell), 2 (4-cell), 3 (8-cell), 4 (16-cell), 5 (early morula), 6 (compact morula), or 7 (blastocyst) days post insemination. On recovery, they were examined for stage of development and snap frozen in liquid nitrogen for the analysis of transcript abundance using real-time polymerase chain reaction. The transcripts studied were glucose transporter 5, sarcosine oxidase, mitochondrial Mn-superoxide dismutase, connexin 43, interferon tau, insulin-like growth factor II, apoptosis regulator box-alpha and insulin-like growth factor-I receptor, most of which are known from our previous work to differ in terms of transcript abundance in blastocysts derived from culture in vitro or in vivo. The results demonstrate that the relative abundance of the transcripts studied varies throughout the preimplantation period and is strongly influenced by the culture environment. In addition, the data demonstrate that changes in transcript abundance in blastocyst stage embryos are in many cases a consequence of perturbed transcription earlier in development. Depending on the transcript, these differences may be evident by as little as 10 h of initiation of culture. Such information has implications not only for basic biology but also for human assisted reproduction in which there is a move toward culturing embryos to the blastocyst stage, necessitating prolonged culture in vitro under potentially deleterious conditions.
