Gap junctions are essential for murine primordial follicle assembly immediately before birth.

In addition, the expression of ovarian somatic cell (OSC)-specific genes, such as Notch2, Foxl2 and Irx3, was negatively affected by GJC blockers, whereas oocyte-related genes, such as Ybx2, Nobox and Sohlh1, were hardly affected, implying that the establishment of GJC during this period may be more important to OSCs than to oocytes.
Genetics of primary ovarian insufficiency: new developments and opportunities.
Jinan, China. In Hum Reprod Update, Nov 2015
Based on candidate gene studies, single gene perturbations unequivocally having a deleterious effect in at least one population include Bone morphogenetic protein 15 (BMP15), Progesterone receptor membrane component 1 (PGRMC1), and Fragile X mental retardation 1 (FMR1) premutation on the X chromosome; Growth differentiation factor 9 (GDF9), Folliculogenesis specific bHLH transcription factor (FIGLA), Newborn ovary homeobox gene (NOBOX), Nuclear receptor subfamily 5, group A, member 1 (NR5A1) and Nanos homolog 3 (NANOS3) seem likely as well, but mostly being found in no more than 1-2% of a single population studied.
Morphological characteristics observed during early follicular development in perinatal MRL/MpJ mice.

However, the beginning of folliculogenesis, as evidenced by the expression of NOBOX oogenesis homeobox (Nobox) transcript and protein, was more enhanced in MRL/MpJ mice than in C57BL/6 mice at embryonic day 18.5 and postnatal day 0. In addition, developed follicles were more frequently observed in MRL/MpJ mice than in C57BL/6 mice between postnatal days 0 and 4. In conclusion, the oocyte development during nest breakdown and folliculogenesis was accelerated in MRL/MpJ mice when compared to that observed in C57BL/6 mice.
Determination and stability of gonadal sex.

In the germ line, oocytes apparently form normally even in the absence of Foxl2, dependent on genes that include female-specific factors such as Fig-alpha, Nobox, etc.
Oogenesis specific genes (Nobox, Oct4, Bmp15, Gdf9, Oogenesin1 and Oogenesin2) are differentially expressed during natural and gonadotropin-induced mouse follicular development.
Pavia, Italy. In Mol Reprod Dev, 2009
RT-PCR data shows an increase in oogenesis specific gene transcripts (Nobox, Oct4, Bmp15, Gdf9, Oogenesin1 and Oogenesin2) between the primordial until the preantral stages, with the exception of the Oogenesin1 transcripts under gonadotropin-induction.
