Abstract
The combination of estrus synchronization and superovulation (SS) treatments causes alterations in ovarian and endometrial gene expression patterns, resulting in abnormal follicle and oocyte growth, fertilization, and embryo development. However, the impact of combined SS treatments on the transcriptome of the surviving embryos remains unidentified. In this study, we examined gene expression changes in day 6 blastocysts that survived a brief regimen of synchronization treatment combined with superovulation. The sows were included in one of three groups: SS7 group (n = 6), sows were administered Altrenogest (ALT) 7 days from the day of weaning and superovulated with eCG 24 h after the end of ALT treatment and hCG at the onset of estrus; SO group (n = 6), ALT nontreated sows were superovulated with eCG 24 h postweaning and hCG at the onset of estrus; control group (n = 6), weaned sows displaying natural estrus. Six days after insemination, the sows underwent a surgical intervention for embryo collection. Transcriptome analysis was performed on blastocyst-stage embryos with good morphology. Differentially expressed genes (DEGs) between groups were detected using one-way ANOVA with an un-adjusted p-value < 0.05 and a fold change </> 1.5. The effect of SO treatment on the number of altered pathways and DEGs within each pathway was minimal. Only four pathways were disrupted comprising only a total of four altered transcripts, which were not related to reproductive functions or embryonic development. On the other hand, the surviving blastocysts subjected to SS7 treatments exhibited moderate gene expression changes in terms of DEGs and fold changes, with seven pathways disrupted containing a total of 10 transcripts affected. In this case, the up-regulation of certain pathways, such as the metabolic pathway, with two up-regulated genes associated with reproductive functions, namely RDH10 and SPTLC2, may suggest suboptimal embryo quality, while the down-regulation of others, such as the glutathione metabolism pathway, with down-regulated genes related to cellular detoxification of reactive oxygen species, namely GSTK1 and GSTO1, could depress the embryos' response to oxidative stress, thereby impairing subsequent embryo development. The gene expression changes observed in the present study in SS7 embryos, along with previous reports indicating SS7 can negatively affect fertilization, embryo production, and reproductive tract gene expression, make its use in embryo transfer programs unrecommendable.

Abstract
Hox genes encode transcription factors that specify the body segment identity during development, including crustaceans, such as amphipods and decapods, that possess a remarkable diversity of segments and specialized appendages. In amphipods, alterations of specialized appendages have been obtained using knockout experiment of Hox genes, which suggests that these genes are involved in the evolution of morphology within crustaceans. However, studies of Hox genes in crustaceans have been limited to a few species. Here, we identified the homeodomain of nine Hox genes: labial (lab), proboscipedia (pb), Deformed (Dfd), Sex combs reduced (Scr), fushi tarazu (ftz), Antennapedia (Antp), Ultrabithorax (Ubx), abdominal-A (abdA), and Abdominal-B (AbdB), and evaluated their expression by RT-qPCR and RT-PCR in the ovary, during embryonic development, and at the first larval stage (Zoea I) of the decapod Macrobrachium olfersii. The transcript levels of lab, Dfd, and ftz decreased and transcripts of pb, Scr, Antp, Ubx, abdA, and AbdB increased during embryonic development. Hox genes were expressed in mature ovaries and Zoea I larval stages, except Scr and ftz, respectively. In addition, isoforms of Dfd, Scr, Ubx, and abdA, which have been scarcely reported in crustaceans, were described. New partial sequences of 87 Hox genes from other crustaceans were identified from the GenBank database. Our results are interesting for future studies to determine the specific function of Hox genes and their isoforms in the freshwater prawn M. olfersii and to contribute to the understanding of the diversity and evolution of body plans and appendages in Crustaceans.
