J Steroid Biochem Mol Biol 2024; 240:106509.

Abstract
Hyperglycemia is known as one of the main causes of infertility in human societies. Indole propionic acid (IPA) is produced by intestinal microbiota and has antioxidant and anti-inflammatory properties. This study aims to investigate the effects of IPA on molecular indices of steroidogenesis, ER stress, and apoptosis induced by high glucose (HG) in granulosa cells. Primary GCs, isolated from ovarian follicles of Rats were cultured in 5 mM (control) and 30 mM (HG) of glucose and in the presence of 10 and 20 µM of IPA for 24 h. The cell viability was assessed by MTT. The gene expression of P450SCC, 3βHSD, CYP19A, BAX, BCL2, and STAR was evaluated by Real-Time PCR. Protein expression of ATF6, PERK, GRP78, and CHOP determined by western blot. Progesterone, estradiol, IL-1β, and TNF-α were measured by ELISA. HG decreased the viability, and expression of P450SCC, 3βHSD, CYP19A, BCL2, STAR, and increased BAX. 10 and 20 µM of IPA increased cell viability, expression of P450SCC, 3βHSD, CYP19A, BCL2 and STAR and decreased BAX compared to the HG group. The expression of ATF6, PERK, GRP78, and CHOP proteins increased by HG and IPA decreased the expression of these proteins compared to the HG group. Also, HG decreased progesterone and estradiol levels and increased IL-1β and TNF-α. IPA significantly increased progesterone and estradiol and decreased IL-1β and TNF-α compared to the HG group. IPA can improve the side effects of HG in GCs of rats, as responsible cells for fertility, by improving steroidogenesis, regulation of ER-stress pathway, suppression of inflammation, and apoptosis.

Expression and Characterization of the Spats1 Gene and Its Response to E2/MT Treatment in the Chinese Soft-Shelled Turtle ( Pelodiscus sinensis). Animals (Basel) 2022; 12:ani12141858. [PMID: 35883403 PMCID: PMC9311554 DOI: 10.3390/ani12141858] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/07/2022] [Revised: 07/11/2022] [Accepted: 07/18/2022] [Indexed: 11/17/2022] Open
Abstract
Spats1 (spermatogenesis-associated, serinerich 1) has been characterized as a male-biased gene which acts an important role in the germ cell differentiation of mammals. Nevertheless, the function of Spats1 in the Chinese soft-shelled turtle (P. sinensis) has not yet been reported. To initially explore the expression of Spats1 in P. sinensis and its response to sex steroid treatment, we cloned the CDS of Spats1 for the first time and analyzed its expression profile in different tissues, including the testes in different seasons. The Spats1 cDNA fragment is 1201 base pairs (bp) in length and contains an open reading frame (ORF) of 849 bp, which codes for 283 amino acids. Spats1 mRNA was highly expressed in the testes (p < 0.01) and barely detectable in other tissues. In P. sinensis, the relative expression of Spats1 also responsive to seasonal changes in testis development. In summer (July) and autumn (October), Spats1 gene expression was significantly higher in the testes than in other seasons (p < 0.05). Spats1 mRNA was found to be specifically expressed in germ cells by chemical in situ hybridization (CISH), and it was mainly located in primary spermatocytes (Sc1), secondary spermatocytes (Sc2) and spermatozoa (St). Spats1 expression in embryos was not significantly changed after 17α-methyltestosterone (MT)and 17β-estradiol (E2) treatment. In adults, MT significantly induced Spats1 expression in male P. sinensis. However, the expression of Spats1 in testes was not responsive to E2 treatment. In addition, the expression of Spats1 in females was not affected by either MT or E2 treatment. These results imply that Spats1 is a male-specific expressed gene that is mainly regulated by MT and is closely linked to spermatogenesis and release in P. sinensis.

Wang Y, Liu X, Yu L, Hong X, Zhao J, Zhu J, Yuan J, Li W, Zhu X. Identification and analysis of novel microRNAs provide insights to reproductive capacity of the cultured Asian yellow pond turtle Mauremys mutica. COMPARATIVE BIOCHEMISTRY AND PHYSIOLOGY D-GENOMICS & PROTEOMICS 2021; 40:100890. [PMID: 34404014 DOI: 10.1016/j.cbd.2021.100890] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 05/30/2021] [Revised: 07/24/2021] [Accepted: 08/03/2021] [Indexed: 10/20/2022]
Abstract
The crucial roles of miRNAs in regulating animal growth, development, and disease resistance have been extensively reported, but their roles in relation to the reproductive capacity of aquatic animals (numbers of eggs laid and hatchlings), especially reptiles, remain unclear. In this study, high-throughput sequencing technology was used to screen miRNAs related to reproductive capacity based on the construction of a cDNA library of ovaries from higher-fecundity (HF) and lower-fecundity (LF) M. mutica. The results showed that 15,767,494 (93.98%) and 14,137,621 (94.17%) high-quality reads were obtained from the HF and LF groups, respectively. We screened 131 miRNAs that were differentially expressed between the HF and LF groups, of which 78 were upregulated and 53 were downregulated compared with the M. mutica reference genome. GO and KEGG pathway enrichment analyses of the target genes of differentially expressed miRNAs revealed significant differences in the enrichment frequencies of genes associated with ATP binding and proteolysis between the HF and LF groups, while the tricarboxylic acid cycle, glucagon signaling pathway and vitamin B6 metabolic pathway were shown to potentially help determine reproductive capacity. Ten miRNAs were verified by qRT-PCR to confirm the reliability and accuracy of the sequencing results, and a miRNA-mRNA target gene interaction network was constructed. These results will further our understanding of the regulatory mechanism of miRNAs in regards to turtle reproductive capacity.
