Using female Wistar rats, we demonstrated that pre-gestational stress negatively affects fertility and pregnancy outcomes. The rats were subjected to restraint stress (RS) for 15 days, with 3 h of stress each day, before mating. The RS group exhibited higher levels of corticosterone and prolactin, along with lower levels of adrenocorticotropic hormone (ACTH), indicating a successful stress model. Stressed rats showed reduced fertility and fecundity indices, longer conception times, and decreased levels of ovarian steroids, such as progesterone, testosterone, and estradiol. Additionally, the ovaries of the RS group had fewer antral follicles and more ovarian cysts. Elevated protein levels of cytochrome P450 side-chain cleavage enzyme (CYP11A1) and aromatase (CYP19A1), along with decreased levels of 17β-hydroxysteroid dehydrogenase (17β-HSD), indicating impaired ovarian steroidogenesis in stress exposed rats. In the RS group, there was a significant increase in proteins associated with folliculogenesis, specifically octamer-binding transcription factor 4 (OCT 4) and growth differentiation factor 9 (GDF 9). Additionally, proteins linked to ovulation, such as the prolactin receptor (PRLR), peroxisome proliferator-activated receptor-γ (PPAR-γ), and cyclooxygenase 2 (COX 2), were elevated. The increased levels of PRLR, progesterone receptor (PR), androgen receptor (AR), and estrogen receptor (ER) combined with heightened oxidative stress in the uteri of the RS group, suggest a potential disruption in uterine function. Overall, this research indicates that pre-gestational stress can significantly impact reproductive health by altering gonadotrophin and ovarian steroid dynamics in the female reproductive tract.</div></div>","PeriodicalId":55598,"journal":{"name":"Gene Expression Patterns","volume":"55 ","pages":"Article 119391"},"PeriodicalIF":1.0,"publicationDate":"2025-02-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143519686","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Berberine, a plant alkaloid which is known to have wound healing properties shows potential to modulate regeneration. The present study aimed to explore the modulating influence of berberine on the signaling pathways involved in zebrafish larvae transected tail fin fold regeneration. Tail fin fold transection was performed on 3 dpf (days post fertilization) zebrafish larvae treated with Berberine (0.01%) and untreated control (System water (SW)). The larvae were observed under a microscope at 0, 1, 2, 3, 4, 5, hours post transection (hpt).

This study explored the physiological role of MDK by analyzing its molecular characterization and spatio-temporal expression dynamics during the growth of sika deer antlers. The study cloned the coding sequences (CDS) of MDK, which spanned 429 bp and encoded 142 amino acids. The results of bioinformatics prediction analysis showed that MDK was an extracellular hydrophilic secreted protein, which was mainly composed of random coil. MDK protein was relatively conserved in evolution and MDK protein of sika deer had the closest relatives to ruminants and the furthest relatives to Aves. The tip tissues (dermis, mesenchyme, precartilage, cartilage) of antlers were collected from three important growth and development nodes (early period, EP. middle period, MP. late period, LP), and quantitative real-time polymerase chain reaction (qRT-PCR) was chosen to detect the spatio-temporal expression of the MDK. The results showed that MDK was expressed in all tissue sites of antler tip in EP, MP, LP. MDK had a consistent expression pattern under all growth periods and was strongly expressed in dermis and cartilage. The expression of MDK was consistently up-regulated in precartilage, whereas it was first up-regulated and then down-regulated in other tissues, and it was highly significant in MP compared to EP and LP (P < 0.01).

Despite the importance of the Hippo pathway for development, including within the nervous system, the expression of the TEAD family remains poorly defined in mammals. Here, we mapped the expression of TEAD1 in the developing mouse brain. We find that TEAD1 expression is confined to progenitor cells during embryonic development, namely radial glia and intermediate progenitor cells.

We also identify expression of TEAD1 in developing and mature ependymal cells of the lateral and third ventricle, including within the subcommissural organ, as well as by cells within the choroid plexuses and the forebrain neurogenic niches.
