BMC Genomics(2021) 22:Web page 2 ofConclusions: The existing study supplied new molecular information for insight into the regulatory mechanism underlying ovarian follicle development associated with egg production in chicken. Keyword phrases: Ovarian follicle, Transcriptome, NDUFAB1 , GABRA1 , Egg productionBackground Egg production initiates from the follicle prehierarchical and hierarchical development, maturation, and ultimately ovulates from the hen ovary, that is governed by the hypothalamic ituitary varian axis [1]. Ovarian follicle development plays a key part inside the egg production capacity, which is characterized by a well-organized follicular hierarchy in high production egg-laying layers. In chickens with low egg-laying prices, e.g., the broiler breeder hen, follicular development is just not well-organized, which leads to lowered productivity [1]. Generally, ovarian follicles may be categorized by size or/and according to color (white or yellow), into no less than four types, which includes little white resting follicles (much less than two mm diameter), slow developing white follicles (GWF, from two mm up to 6 mm diameter), modest yellow follicles (SYF, six as much as 8 mm) of recruitment in to the follicular hierarchy (at the stage of follicle choice), and huge yellow follicles (LWF) at the differentiated preovulatory stage, getting 9 to 12 mm in diameter and 5 to six hierarchical follicles of enhanced sizes (from F6 to F1) in hen ovary [4, 5]. Within the various phases of follicular development, numerous divergent biological processes impact oocyte growth, and proliferation and differentiation of granulosa and theca cells inside the various-sized follicles [4, 6, 7]. In addition, a plethora of ovarian paracrine and autocrine elements was involved in regulation of your follicle development and its function also as the positive or damaging controls through the endocrinal hormones in the hypothalamus and pituitary, which includes gonadotropin releasing hormone (GNRH), gonadotropin inhibitory hormone (GNIH), and follicle stimulating hormone (FSH) [1, 2, 8]. Within the ovary, one of the most representative hormones and growth elements for example steroidogenic-related enzymes steroidogenic acute regulatory protein (STAR), hydroxysteroid (17beta) dehydrogenase 1 (HSD17B1) and cytochrome P450 side-chain cleavage (P450scc/ CYP11A1), intra-ovarian hormones progesterone (P4), estradiol (E2) and anti-m lerian hormone (AMH), cell proliferation or apoptosis-related components Bcl-2, cyclin D1 (CCND1) and caspase-3 (CASP3), which have indispensable effects on follicular development, follicle selection or atresia, finally on their preovulatory improvement and ovulation, creating the early developmental variations of ovarian follicles and egg production capacity in adult layers highly correlated, have been intensively investigat
