1. FOXL2 gene mutations cause blepharophimosis-ptosis-epicanthus inversus syndrome (BPES) and may be associated with premature ovarian insufficiency (POI). Premature ovarian insufficiency as a variable feature of blepharophimosis, ptosis, and epicanthus inversus syndrome associated with c.223C > T p.(Leu75Phe) FOXL2 mutation

2. Mutation analysis of a large blepharophimosis, ptosis, and epicanthus inversus cohort identified a wide range of mutations distributed throughout FOXL2 and revealed a very strong paternal inheritance bias.

3. The c.843_859dup17 frameshift mutation probably underlies the blepharophimosis-ptosis-epicanthus inversus type I in this Chinese pedigree

4. The research on the molecular pathogenesis of FOXL2 in BPES.

5. We observed no significant difference associated with POI in the patients when compared with a healthy control group (p > 0.05). Also, no exonic variants were found for the genes BMP15 and FOXL2 in the individuals tested

6. These results confirmed that FOXL2 disruption in KGN cells is associated with the cell cycle attenuation.

7. We detected two novel missense mutations, c.162G>T (p.Lys54Asn) and c.308G>A (p.Arg103His), in the FOXL2 gene; one in each of the study families. Bioinformatics did predict that the two mutations were likely damaging to protein function.

8. Thus, FOXL2C134W potentiates CYP19 expression in HGrC1 cells via enhanced recruitment of SMAD3 to a proximal FOX binding element.

9. In the present study, we analysed two Han Chinese families with BPES type I and identified two novel mutations (c.462_468del and c.988_989insG). Immunofluorescence and confocal microscopy revealed that the extended FOXL2, p.Ala330Glyfs*204, induced significant mislocalization and aggregation.

10. Three loci with high mutation frequencies, the 138665410 FOXL2 gene variant, the 23862952 MYH6 gene variant, and the 71098693 HYDIN gene variant were found to be significantly associated with sporadic Atrial Septal Defect (P<0.05); variants in FOXL2 and MYH6 were found in patients with isolated, sporadic Atrial Septal Defect (P<5x10-4).

11. We describe a girl and her father with isolated BPES without an intragenic mutation in FOXL2. MLPA of a FOXL2 enhancer region identified a small microdeletion at 234 kb upstream of FOXL2. This deletion fully includes the PISRT1 gene, a noncoding gene which is part of a cis-regulatory element of FOXL2

12. MiR-937 inhibits the proliferation and metastasis of gastric cancer cells by targeting FOXL2 via inactivation of PI3K/AKT signaling pathway. These results suggest that miR-937 may be a potential target for the treatment of gastric cancer.

13. This study demonstrated the existence of an AMH-FOXL2 relationship in hGCs. AMH is capable of increasing both gene and protein expression of FOXL2. Because FOXL2 induces AMH transcription, these ovarian factors could be finely regulated by a positive feedback loop mechanism to preserve the ovarian follicle reserve.

14. A novel FOXL2 indel mutation was identified in Chinese families with BPES. Our results expand the spectrum of known FOXL2 mutations and provide additional insight into the structure-function relationships of the FOXL2 protein.

15. The adult granulosa cell tumor (AGCT)-like components are likely to be tumor-like proliferations but not truly neoplastic AGCT. FOXL2 mutation testing may be useful in confirming an AGCT-like component.

16. This novel duplicate mutation (c.844_860dup17, p.His291Argfs*71) in FOXL2 was identified in a Chinese family with both types of BPES. These findings expand current knowledge of the mutation spectrum of the FOXL2 gene and confirmed the intrafamily phenotypic heterogeneity of BPES.

17. The study shows that half of granulosa theca cell tumors harbor the same FOXL2 mutation that characterizes adult granulosa cell tumors but there is no outcome evidence to guide whether mutation status should alter the classification of the tumor or the management of the patient.

18. The promoter of FOXL2 was successfully cloned and registered in Gen Bank, and a dual luciferase reporter (DLR) analysis demonstrated that the luciferase activity was significantly induced by the promoter of FOXL2. Subsequently, bioinformatics analysis indicated that FOXL2 may be regulated by STAT3.

19. This study demonstrated that the transactivation of FOXL2 driven by interactions between HMGA2 and pRb might exert critical effects on the metastases and EMT of chemoresistant gastric cancer. Blocking the HMGA2-FOXL2-ITGA2 pathway could serve as a new strategy for gastric cancer treatment.

20. A novel deletion mutation (C.634_641 del, CCCATGC) between the forkhead domain and the polyalanine domain was found, resulting in a frameshift mutation and a truncated protein.

1. comparison of FOXL2 genome-wide occupancy in the fetal ovary with testis-determining factor SOX9 genome-wide occupancy in the fetal testis revealed extensive overlaps, implying that antagonistic signals between FOXL2 and SOX9 occur at the chromatin level.

2. We found that endometrial cells expressing low FOXL2 levels, either endogenous or genetically manipulated, were associated with a higher attachment rate of mouse blastocysts. low-FOXL2 levels were associated with changes in the expression level of components of the Wnt/Fzd and apoptotic pathways, both of which are involved in uterine receptivity.

3. Testis determination involves FGFR2c-mediated repression of both the WNT4- and FOXL2-driven ovarian-determining pathways.

4. direct overexpression of Foxl2 decreased the expression of Sertoli cell-specific genes in primary Sertoli cells. Taken together, these results demonstrate that repression of beta-catenin (CTNNB1) signaling is required for lineage maintenance of Sertoli cells.

5. evidence that FOXL2 modulates Col1a2 transcription through interaction with a response element 65 Kb upstream of the transcription start site

6. Data indicate that a balance between supporting cell self-renewal and differentiation is maintained in the developing ovary by relative Wnt4 protein/beta-catenin and p27Kip1 protein (p27)/Forkhead box L2 (FOXL2) activities.

7. Data indicate that the hypothalamic-pituitary-gonadal axis controls expression of Foxl2 in pituitary gonadotropes primarily through positive feedback from ovarian hormones.

11. 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-induced adrenocortical tumors of the mouse.

12. our results demonstrate the necessity of FOXL2 for proper FSH production in mice and implicate FOXL2 in integration of transcription factors at the level of the FSHbeta promoter.

13. Results show that a piggyBac insertion ~160 kb upstream of the transcription start site of Foxl2 partially disrupted its expression resulting in BPES (Blepharophimosis, ptosis, epicanthus inversus syndrome)-like conditions.

14. AMH is an endogenous target gene of FOXL2. AMH and FOXL2 collaboratively work to reserve ovarian follicles.

15. In this review, we focus on the role of four specific FOX factors (FOXD1, FOXL2, FOXO1 and FOXP3) in gonadotropin hormone production

16. When the Smad4 gene is ablated in combination with its DNA binding cofactor Foxl2 in gonadotrope cells, mice make essentially no FSH and females are sterile.
