“…The largest yellow follicle, designated as F1, is the most mature and ovulates first. In laying hens, the follicle number in the preovulatory hierarchy is kept by the recruitment of one follicle from the group of 6–8 mm follicles on a near-daily basis [ 1 ].…”

Many matrix metalloproteinases (MMPs) are produced in the mammalian reproductive system and participate in the regulation of its functions. In birds, the limited information available thus far indicates that MMPs are significant regulators of avian ovarian and oviductal functions, too. Some MMPs and inhibitors of MMPs are present in the hen reproductive tissues and their abundances and/or activities change according to the physiological state. The intraovarian role of MMPs likely includes the remodeling of the extracellular matrix (ECM) during folliculogenesis, follicle atresia, and postovulatory regression. In the oviduct, MMPs are also involved in ECM turnover during oviduct development and regression. This study provides a review of the current knowledge on the presence, activity, and regulation of MMPs in the female reproductive system of birds.

“…Follicles were gently rolled on a paper towel to remove connective tissue, then transferred to a Petri dish containing Dulbecco's Modified Eagle's medium (DMEM; Thermo Fisher Scientific). Follicles were weighed and based on diameter, weight, and color, were categorized as the most recently recruited follicle (9-12 mm in diameter, weight 280-900 mg, dark yellow) or prerecruitment follicles (6-8 mm in diameter, 150-270 mg, light yellow) (Ghanem & Johnson, 2019b).…”

“…Non-reverse-transcribed samples were generated for each sample as negative controls to confirm the absence of genomic DNA contamination. qPCR was performed as previously described (Ghanem & Johnson, 2019b) using the primers described in Table 1. Standard curves were generated for each gene using a synthetic double-stranded DNA of the amplicon sequence.…”

A shotgun proteomics study using isobaric tags for relative and absolute quantification labeling was conducted to characterize proteins in chicken ovarian follicles immediately before and after cyclic recruitment. Granulosa cell (GC) layers from the most recently recruited follicle (GC9) and from each of the four largest prerecruitment follicles (GC1-4) plus theca tissue (TH) from the most recently recruited (TH9) and largest prerecruitment (TH1) follicles were compared. Of 1535 proteins identified, none were determined to be differentially expressed between TH9 and TH1. A pairwise comparison between GC9 and GC1, GC2, GC3, or GC4 resulted in one, five, five, and six differentially expressed proteins, respectively, including yolk and cholesterol transport proteins (vitellogenin 1-3 and apolipoprotein B). In addition, transforming growth factor-beta 1 and microRNA-21 pathways were predicted to be activated at recruitment. We also report, for the first time, the expression of the neuropeptide, RELAXIN-3 (RLN3), in GC. Quantitative polymerase chain reaction determined RLN3 expression to be highest in GC9 and GC1, but its receptors, RXFP1 and RXFP3, were highest in TH and ovarian stroma, respectively. Overall, cyclic recruitment is associated with changes in protein expression predominantly within follicle GC, and a potential role for RLN3 in follicle recruitment and the initiation of GC differentiation warrants further investigation.
