[PMID: 37269598 DOI: 10.1016/j.theriogenology.2023.05.026] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/28/2023] [Revised: 05/24/2023] [Accepted: 05/26/2023] [Indexed: 06/05/2023]
Abstract
This study investigated how lncRNA Meg3 affects the onset of puberty in female rats. We determined Meg3 expression in the hypothalamus-pituitary-ovary axis of female rats at the infancy, prepubertal, pubertal, and adult life stages, using quantitative reverse transcription polymerase chain reaction (qRT-PCR). We also assessed the effects of Meg3 knockdown on the expression levels of puberty-related genes and Wnt/β-catenin proteins in the hypothalamus, time of puberty onset, levels of reproductive genes and hormones, and ovarian morphology in female rats. Meg3 expression in the ovary varied significantly between prepuberty and puberty (P < 0.01). Meg3 knockdown decreased the expression of Gnrh, and Kiss1 mRNA (P < 0.05) and increased the expression of Wnt (P < 0.01) and β-catenin proteins (P < 0.05) in the hypothalamic cells. Onset of puberty in Meg3 knockdown rats was delayed compared to the control group (P < 0.05). Meg3 knockdown decreased Gnrh mRNA levels (P < 0.05) and increased Rfrp-3 mRNA levels (P < 0.05) in the hypothalamus. The serum concentrations of progesterone (P4) and estradiol (E2) of Meg3 knockdown rats were lower than those in the control animals (P < 0.05). Higher longitudinal diameter and ovary weight were found in Meg3 knockdown rats (P < 0.05). These findings suggest that Meg3 regulates the expression of Gnrh, Kiss-1 mRNA and Wnt/β-catenin proteins in the hypothalamic cells, and Gnrh, Rfrp-3 mRNA of the hypothalamus and the serum concentration of P4 and E2, and its knockdown delays the onset of puberty in female rats.

A novel de novo partial xq duplication in a girl with short stature, nonverbal learning disability and diminished ovarian reserve - effect of growth hormone treatment and fertility preservation strategies: a case report and up-to-date review. INTERNATIONAL JOURNAL OF PEDIATRIC ENDOCRINOLOGY 2020; 2020:1. [PMID: 31938033 PMCID: PMC6953468 DOI: 10.1186/s13633-019-0071-z] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 08/01/2019] [Accepted: 10/28/2019] [Indexed: 01/15/2023]
Abstract
Background Xq duplication is a rare condition with a very variable phenotype, which could mimic other genetic syndromes involving the long arm of chromosome X. Sometimes short stature and diminished ovarian reserve (DOR) may be present. Treatments with rGH (Recombinant growth Hormon) or with fertility preservation strategies have not been previously described. Case presentation We present the case of a female with a novel de novo Xq partial duplication (karyotype: 46,Xder(X)(qter→q21.31::pter→qter) confirmed by array-CGH analysis. She presented with short stature, Nonverbal Learning Disability, developmental delay during childhood, severe scoliosis, spontaneous onset of menarche and irregular menstrual cycles. AMH (Anti-Müllerian Hormone) allowed detection of a preserved but severely diminished ovarian reserve with a POI (Premature Ovarian insufficiency) onset risk. She was effectively subjected to fertility preservation strategies and rGH therapy. We also reviewed other published cases with Xq duplication, reporting the main clinics characteristics and any adopted treatment. Conclusions rGH treatment and cryopreservation in a multidisciplinary approach are good therapeutic strategies for Xq duplication syndrome with short stature and premature ovarian failure.

J Pediatr Adolesc Gynecol 2016; 29:e39-42. [PMID: 26639996 DOI: 10.1016/j.jpag.2015.11.010] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.1] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/10/2015] [Revised: 11/18/2015] [Accepted: 11/23/2015] [Indexed: 10/22/2022]
Abstract
BACKGROUND The objective of the study was to describe a novel Xp13.2 chromosome microduplication in a child with some features of Turner syndrome but with menorrhagia after normal menarche. We used clinical evaluation and high resolution chromosome (microarray) analysis. CASE A 15-year-old girl with typical (short stature, pulmonic stenosis, widely-spaced nipples) and atypical (Madelung deformity, menorrhagia) manifestations of Turner syndrome had a novel chromosome constitution with extra material (microduplication) at band Xq13.2 that contained the X-inactive-specific-transcript locus. She also had connective tissue laxity, suggestive of vessel fragility as a contributor to her menorrhagia as well as her diagnosis of von Willebrand disease. This first case of selective X-inactive-specific-transcript locus duplication suggests a role for gene repression in Turner syndrome and other disorders that affect ovarian function. CONCLUSION High-resolution chromosome (microarray) analysis, now a standard of care, will provide new insights into adolescents with abnormal growth and reproductive tract symptoms, especially when accompanied by congenital anomalies.
