  1. COUP-TFII (show NR2F2 Proteins) cooperates with the nuclear receptor steroidogenic factor 1 (SF1 (show NR5A1 Proteins)) to further enhance Insl3 promoter activity in Leydig cells.

  2. Microarray expression profiling of whole adrenal mRNA from ovariectomized vs. intact mice demonstrated selective upregulation of gonadal-like genes including Spinlw1 and Insl3 in GDX (show UBL4A Proteins)-induced adrenocortical tumors of the mouse.

  3. Our data suggest that beta-catenin (show CTNNB1 Proteins) and NOTCH1 (show NOTCH1 Proteins) pathways are potential targets of INSL3 signaling during gubernacular development.

  4. Data suggest that Insl3/Rxfp2 (show RXFP2 Proteins) (insulin-like peptide 3/relaxin receptor 2 (show RXFP2 Proteins)) signaling is important for testicular descent; however, germ-cell deletion of Rxfp2 (show RXFP2 Proteins) did not affect spermatogenesis, germ cell survival, or male fertility.

  5. beta-catenin (show CTNNB1 Proteins) and Notch (show NOTCH1 Proteins) pathways are potential targets of INSL3 signaling during gubernacular development.

  6. INSL3 is a powerful and multifunctional promoter of tumor growth and angiogenesis in human thyroid cancer cell xenografts. INSL3 actions involve RXFP2 (show RXFP2 Proteins) activation and the secretion of S100A4 (show S100A4 Proteins) and (pro-)cathepsin-L (show CTSL1 Proteins)

  7. Poorly formed gubernacula and increased testicular mobility in Insl3 mutant mice result in spermatic cord anomalies, delayed/absent testicular descent and subsequent testicular torsion in a gene dose dependent manner

  8. overexpression of the insl3 in female mice causes descent of the ovaries

  9. Mutations in INSL3 might contribute to the etiology of cryptorchidism.I

  10. Insl3 expression causes inguinal hernia in females; gubernaculum formation is the most sensitive biological response as regards Insl3

Human Insulin-Like 3 (Leydig Cell) (INSL3) interaction partners

  1. Healthy eumenorrheic late adolescent females with sporadic anovulation display higher INSL3 blood concentration.

  2. rs6523 polymorphism and AGAG haplotype of INSL3 showed significant association with increased risk of polycystic ovary syndrome.

  3. INSL3 in girls is a unique and specific marker of theca cells surrounding antral follicles.

  4. Three common INSL3 gene polymorphisms (27G>A, 126G>A, 178G>A) unrelated to any particular phenotype of testicular maldescent (TMD (show TTN Proteins)) were detected both in patients and controls, indicating that INSL3 gene mutations are not a common cause of TMD (show TTN Proteins).

  5. DLK1 (show DLK1 Proteins), INSL3 and COUP-TFII (show NR2F2 Proteins) expression changes during normal development and is linked to different stages of Leydig Cell differentiation.

  6. low INSL3 concentration is related to the pathogenesis behind an unfavourable change in body composition and bone metabolism among Klinefelter syndrome patients

  7. The aim of this study was to assess plasma INSL3 in patients with osteoporosis and Klinefelter's Syndrome compared to healthy males.

  8. INSL3 is as sensitive a marker as T for the evaluation of altered Leydig cell function in congenital hypogonadotropic hypogonadism/Kallmann syndrome patients.

  9. INSL3 and AMH (show AMH Proteins) levels are significantly correlated with each other in women with PCOS, and they are significantly increased, particularly in the presence of amenorrhea and oligomenorrhea.

  10. Findings suggest a novel and gender-specific role for INSL3 and cognate receptor RXFP2 (show RXFP2 Proteins) signaling in ocular surface homeostasis.

Pig (Porcine) Insulin-Like 3 (Leydig Cell) (INSL3) interaction partners

  1. This study thus provides evidence for substantial transfer of INSL3 between fetuses, and probably also across the placenta, emphasizing the vulnerability of the fetus to extrinsic hormonal influences within the uterus.

  2. RXFP2 (show RXFP2 Proteins) was expressed in boar meiotic and post-meiotic germ cells, where INSL3 neutralization led to increased germ cell apoptosis and reduced sperm output, suggesting that INSL3 acts as a survival/anti-apoptotic factor in maintaining sperm production.

  3. The study suggests the existence of RLF/INSL3-RXFP2 (show RXFP2 Proteins) signaling in germ cells of boars.

  4. Circulating INSL3 was shown to increase progressively during development

  5. These results indicate that boar RLF/INSL3 is secreted from testicular Leydig cells as a B-C-A monomeric structure with full biological activity.

  6. insl3 gene SNPs can be excluded as a common genetic basis for hernia inguinalis in pigs

Cow (Bovine) Insulin-Like 3 (Leydig Cell) (INSL3) interaction partners

  1. These results suggested an acute regulation of INSL3 by luteinizing hormone (LH) because INSL3 concentrations increased immediately after endogenous and exogenous LH stimulation.

  2. INSL3 plays a luteotropic role as a local regulator in the bovine corpus luteum.

  3. BMP6 (show BMP6 Proteins) has a role in downregulating INSL3 and CYP17A1 (show CYP17A1 Proteins) and other proteins that modulate ovarian androgen production

  4. The likely role of INSL3 as an important intrafollicular modulator of thecal interna cell function/steroidogenesis.

  5. INSL3 provides the first example of a gender-specific fetal hormone with the potential to influence both placental and maternal physiology

  6. relaxin-like factor mRNA was highly expressed in the corpus luteum on days 7 and 14 of pregnancy

INSL3 Protein Profile

Protein Summary

This gene encodes a member of the insulin-like hormone superfamily. The encoded protein is mainly produced in gonadal tissues. Studies of the mouse counterpart suggest that this gene may be involved in the development of urogenital tract and female fertility. This protein may also act as a hormone to regulate growth and differentiation of gubernaculum, and thus mediating intra-abdominal testicular descent. Mutations in this gene may lead to cryptorchidism. Alternate splicing results in multiple transcript variants.
