Abstract
Vitamin D deficiency poses a widespread health challenge, shaped by environmental and genetic determinants. A recent discovery identified a genetic regulator, rs11542462, in the SDR42E1 gene, though its biological implications remain largely unexplored. Our bioinformatic assessments revealed pronounced SDR42E1 expression in skin keratinocytes and the analogous HaCaT human keratinocyte cell lines, prompting us to select the latter as an experimental model. Employing CRISPR/Cas9 gene-editing technology and multi-omics approach, we discovered that depleting SDR42E1 showed a 1.6-fold disruption in steroid biosynthesis pathway (P-value = 0.03), considerably affecting crucial vitamin D biosynthesis regulators. Notably, SERPINB2 (P-value = 2.17 × 10-103), EBP (P-value = 2.46 × 10-13), and DHCR7 (P-value = 8.03 × 10-09) elevated by ∼2-3 fold, while ALPP (P-value <2.2 × 10-308), SLC7A5 (P-value = 1.96 × 10-215), and CYP26A1 (P-value = 1.06 × 10-08) downregulated by ∼1.5-3 fold. These alterations resulted in accumulation of 7-dehydrocholesterol precursor and reduction of vitamin D3 production, as evidenced by the drug enrichment (P-value = 4.39 × 10-06) and total vitamin D quantification (R2 = 0.935, P-value = 0.0016) analyses. Our investigation unveils SDR42E1's significance in vitamin D homeostasis, emphasizing the potential of precision medicine in addressing vitamin D deficiency through understanding its genetic basis.

Abstract
RFRP-3 is a functional ortholog of avian GnIH and regulates reproductive activities in the gonads of animals. However, the role of RFRP-3 in the function of ovarian granulosa cells in mice remains unclear. First, we detected the expression of the RFRP-3 receptor (GPR147) in the ovarian granulosa cells of mice. Second, the effect of RFRP-3 treatment on estradiol and progesterone secretions from granulosa cells was tested by ELISA. Meanwhile, the expression of genes and proteins regulating steroid hormone synthesis was respectively examined by qPCR and western blot. Furthermore, the effect of RFRP-3 treatment on the apoptosis of granulosa cells was analyzed. The results revealed that the GPR147 protein (a RFRP-3 receptor) was expressed in the ovarian granulosa cells of mice. Low and medium doses RFRP-3 treatment significantly reduced progesterone secretion in the granulosa cells (P < 0.05), while RFRP-3 suppressed p450scc, 3β-HSD, StAR, and FSHR expression in a non-dose-dependent manner. Moreover, RFRP-3 treatment might induce the apoptosis of granulosa cells. Additionally, low doses RFRP-3 significantly reduced p-ERK1/2 protein expression (P < 0.05) in the ovarian granulosa cells. We here, for the first time, confirmed that GPR147 was expressed in the ovarian granulosa cells of mice. Our findings suggested that and RFRP-3 regulates the granulosa cell function through the ERK signaling pathway, which will lay the foundation for uncovering molecular mechanisms by which RFRP-3 regulates follicle development in future.

Abstract
Steroid hormones secreted by granulosa cells are essential for maintaining normal development of chicken follicles. Our previous sequencing data indicated that miR-181b-5p and RAS-related protein 1B (RAP1B) appeared to function in chicken granulosa cells, which was further explored in this study. The results suggested that miR-181b-5p facilitated the aggregation of lipid droplets and the synthesis of progesterone. In contrast, RAP1B astricted lipid deposition and progesterone secretion. Cotransfection of the RAP1B overexpression vector with miR-181b-5p mimic eliminated the promoting effect of miR-181b-5p. Dual-luciferase reporter assay confirmed that miR-181b-5p bound directly to the 3' untranslated region (3' UTR) of RAP1B. We also found that miR-181b-5p and RAP1B reduced and enhanced the phosphorylation levels of extracellular signal-regulated kinases 1 and 2 (ERK1/2), respectively. The application of ERK1/2 activators and inhibitors demonstrated that ERK1/2 is a negative regulator of lipid deposition and progesterone synthesis. In conclusion, we revealed that miR-181b-5p accelerated lipid deposition and progesterone synthesis through the RAP1B/ERK1/2 pathway in chicken granulosa cells. miR-181b-5p and RAP1B may serve as new biomarkers in breeding to improve chicken reproductive performance and prevent ovary-related diseases.

RFRP-3 Influences Apoptosis and Steroidogenesis of Yak Cumulus Cells and Compromises Oocyte Meiotic Maturation and Subsequent Developmental Competence. Int J Mol Sci 2023; 24:ijms24087000. [PMID: 37108163 PMCID: PMC10138887 DOI: 10.3390/ijms24087000] [Citation(s) in RCA: 4] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/13/2023] [Revised: 04/03/2023] [Accepted: 04/09/2023] [Indexed: 04/29/2023] Open
Abstract
RF amide-related peptide 3 (RFRP-3), a mammalian ortholog of gonadotropin-inhibitory hormone (GnIH), is identified to be a novel inhibitory endogenous neurohormonal peptide that regulates mammalian reproduction by binding with specific G protein-coupled receptors (GPRs) in various species. Herein, our objectives were to explore the biological functions of exogenous RFRP-3 on the apoptosis and steroidogenesis of yak cumulus cells (CCs) and the developmental potential of yak oocytes. The spatiotemporal expression pattern and localization of GnIH/RFRP-3 and its receptor GPR147 were determined in follicles and CCs. The effects of RFRP-3 on the proliferation and apoptosis of yak CCs were initially estimated by EdU assay and TUNEL staining. We confirmed that high-dose (10-6 mol/L) RFRP-3 suppressed viability and increased the apoptotic rates, implying that RFRP-3 could repress proliferation and induce apoptosis. Subsequently, the concentrations of E2 and P4 were significantly lower with 10-6 mol/L RFRP-3 treatment than that of the control counterparts, which indicated that the steroidogenesis of CCs was impaired after RFRP-3 treatment. Compared with the control group, 10-6 mol/L RFRP-3 treatment decreased the maturation of yak oocytes efficiently and subsequent developmental potential. We sought to explore the potential mechanism of RFRP-3-induced apoptosis and steroidogenesis, so we observed the levels of apoptotic regulatory factors and hormone synthesis-related factors in yak CCs after RFRP-3 treatment. Our results indicated that RFRP-3 dose-dependently elevated the expression of apoptosis markers (Caspase and Bax), whereas the expression levels of steroidogenesis-related factors (LHR, StAR, 3β-HSD) were downregulated in a dose-dependent manner. However, all these effects were moderated by cotreatment with inhibitory RF9 of GPR147. These results demonstrated that RFRP-3 adjusted the expression of apoptotic and steroidogenic regulatory factors to induce apoptosis of CCs, probably through binding with its receptor GPR147, as well as compromised oocyte maturation and developmental potential. This research revealed the expression profiles of GnIH/RFRP-3 and GPR147 in yak CCs and supported a conserved inhibitory action on oocyte developmental competence.

CircEML1 facilitates the steroid synthesis in follicular granulosa cells of chicken through sponging gga-miR-449a to release IGF2BP3 expression. Genomics 2023; 115:110540.

Abstract
Non-coding RNAs (ncRNAs) induced competing endogenous RNAs (ceRNA) play crucial roles in various biological process by regulating target gene expression. However, the studies of ceRNA networks in the regulation of ovarian ovulation processing of chicken remains deficient compared to that in mammals. Our present study revealed that circEML1 was differential expressed in hen's ovarian tissues at different ages (15 W/20 W/30 W/68 W) and identified as a loop structure from EML1 pre-mRNA, which promoted the expressions of CYP19A1/StAR and E2/P4 secretion in follicular granulosa cells (GCs). Furthermore, circEML1 could serve as a sponge of gga-miR-449a and also found that IGF2BP3 was targeted by gga-miR-449a to co-participate in the steroidogenesis, which possibly act the regulatory role via mTOR/p38MAPK pathways. Meanwhile, in the rescue experiment, gga-miR-449a could reverse the promoting role of circEML1 to IGF2BP3 and steroidogenesis. Eventually, this study suggested that circEML1/gga-miR-449a/IGF2BP3 axis exerted an important role in the steroidogenesis in GCs of chicken.

Abstract
Photoperiod is an important environmental factor that influence seasonal reproduction behavior in bird and GnIH can play a function in this process through the reproductive axis, and some studies suggest that GnIH may have a direct role at the gonadal level. To investigate the expression of GnIH and its effects on follicle development and steroidogenesis in quail ovaries under different photoperiods, 72 healthy laying quails of 8-wk-old were randomly divided into long day (LD) group [16 light (L): 8 dark (D)] (n = 36) and short day (SD) group (8L:16D) (n = 36). Samples were collected from each group on d1, d11, d22, and d36 of the experiment. The result showed that short day treatment upregulated the level of GnIH in the gonads (P < 0.05), decreased the expression level of CYP19A1,3β-HSD, StAR, LHR, and FSHR and increased the expression level of AMH, AMHR2, GDF9, and BMP15 to inhibit follicle development and ovulation, thus affecting the egg production performance of quails. In vitro culture of quail granulosa cells and treatment with different concentrations of GnIH (0, 1, 10, and 100 ng/mL) for 24 h. Result showed that GnIH inhibited the levels of FSHR, LHR, and steroid synthesis pathways in granulosa cells, upregulated the levels of AMHR2, GDF9, and BMP15. The results suggest that the inhibition of follicle development and reduced egg production in quail by short day treatment is due to GnIH acting at the gonadal level, and GnIH affected the steroid synthesis by inhibiting gonadotropin receptors.
