Abstract
1. The Wnt signalling pathway is centred on the fact that catenin beta-1(CTNNB1) participates in the regulation of ovarian follicle development. The aim of the following study was to identify the polymorphism in the 5' regulatory region of the chicken CTNNB1 gene and evaluate the association between SNPs and egg production traits.2. The study demonstrated that the 5' regulatory region of the CTNNB1 gene has ten SNPs in the chicken flock. After Bonferroni correction for multiple testing, five SNPs (rs315692306, 2:g43385123, rs735854102, 2:g43385457 and rs737907370) were significantly correlated with egg laying traits.3. An association study of the haplotypes with egg laying traits revealed that both haplotypes in block 1 (consisting of rs735052881, rs740662190, rs315692306, and 2:43385123) and block 2 (consisting of rs735854102 and 2:g43385457) were associated with point of lay age and the number of eggs laid at 18-23 weeks. Prediction of transcription factor binding sites showed that transcription factors changed after mutation in block 2. The luciferase assay revealed that the priming activity of the CA haplotype in block2 was the highest.4. Taken together, the rs315692306, 2:g43385123, rs735854102, 2:g43385457 and rs737907370 in the 5' regulatory region of the CTNNB1 gene have significant impacts on egg production.

[PMID: 35059524 PMCID: PMC8760543 DOI: 10.1016/j.heliyon.2022.e08742] [Citation(s) in RCA: 5] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/13/2021] [Revised: 11/05/2021] [Accepted: 01/07/2022] [Indexed: 12/23/2022] Open
Abstract
Ovary follicular development is a progressive system from the beginning of small cortical follicles to the ovulation of hierarchical follicles. The review was conducted to provide information on the indigenous chickens commonly used for egg production, chicken ovarian follicles morphology and expression of growth differentiation factor 9 (GDF9) gene in ovarian follicles and its relationship with egg production. The research databases used in the study include google scholar, Science Direct, PubMed, JSTOR and Cambridge Core. Google, Yahoo and Baidu search engines were used to search the information. In this study, the papers selected for use were original research articles and reviews to ensure that the information used was from research results. Besides, only recent English papers, 2010-2021, were used. The keywords used to search for articles were chicken ovarian follicles, ovarian morphology and GDF9 gene expression. The documents showed that pre-hierarchical follicles include many small and large white follicles, which are about 2-5mm in diameter and 5 to 6 small yellow follicles (SYF) that are about 5-10mm in diameter. Preovulatory follicles are about five to six in number and above 10mm in diameter, with the sizes from F6 to F1, with F1 as the largest follicle. Further, the studies revealed that GDF9 gene mRNA is expressed in the highest concentration in small yellow follicles and other studies reported that the expression of GDF9 gene has been found in follicles of the primary to preovulatory stages in chickens. This review concludes that the GDF9 gene expression is mainly throughout follicular growth and it stimulates the proliferation of pre-hierarchical granulosa cells. The increased egg production in chickens depends on progressive developmental stages and the growth of ovarian follicles.

The anti-Müllerian hormone gene's second exon is associated with the reproductive performance of Jinghai Yellow chickens. Arch Anim Breed 2021; 64:45-52. [PMID: 34084903 PMCID: PMC8130546 DOI: 10.5194/aab-64-45-2021] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/01/2020] [Accepted: 12/17/2020] [Indexed: 11/22/2022] Open
Abstract
Anti-Müllerian hormone (AMH), a member of the transforming growth
factor-β superfamily, plays important regulatory roles in follicular
development and sex differentiation. Although much has been learned about
the impact of polymorphisms of AMH on reproduction in animals, the effect on
chicken reproduction is not well explored. In this study, the polymorphism
of five exons of AMH gene and its effect on the reproductive performance of Jinghai
Yellow chickens were studied. Primers for the amplification of AMH exons were
designed, and Sanger sequencing was performed. Finally, only the polymorphism
in the second exon of the AMH gene was found in the present population. Polymorphisms
in the second exon of the AMH gene in 246 Jinghai Yellow hens and their
associations with reproductive traits were analyzed. In total, four single nucleotide polymorphism (SNP)
mutations were detected in the second exon of the AMH gene: g.1868A>C (AA, aa and Aa); g.1883G>A (BB, bb and Bb);
g.1987G>A (CC, cc and Cc); and g.1996A>G (DD, dd and
Dd). Only the mutation of g.1996A>G affected the reproductive
traits: the age of laying first egg (AFE) of dd genotype was
significantly (p<0.01) earlier than that in the DD and Dd hens. Moreover, the egg
number by 300 d old (EN300) of dd individuals was significantly
higher than that of DD and Dd individuals (p<0.01). Thus, we inferred that the dd
genotype is the beneficial genotype. Additionally, AFE and EN300 showed
significantly better performance in both the H2H2 and H7H7 diplotypes
compared with other diplotype individuals (p<0.01). Thus, the H2H2 and H7H7
genotype had the best combination of AFE and EN300. Our study may allow for
molecular marker section in poultry breeding.

Abstract
1. Egg-laying performance reflects the overall reproductive performance of breeding hens. The genetic traits for egg-laying performance have low or medium heritability, and, depending on the period involved, usually ranges from 0.16 to 0.64. Egg-laying in chickens is regulated by a combination of environmental, endocrine and genetic factors. 2. The main endocrine factors that regulate egg-laying are gonadotropin-releasing hormone (GnRH), prolactin (PRL), follicle-stimulating hormone (FSH) and luteinising hormone (LH). 3. In the last three decades, many studies have explored this aspect at a molecular genetic level. Recent studies identified 31 reproductive hormone-based candidate genes that were significantly associated with egg-laying performance. With the development of genome-sequencing technology, 64 new candidate genes and 108 single nucleotide polymorphisms (SNPs) related to egg-laying performance have been found using genome-wide association studies (GWAS), providing novel insights into the molecular genetic mechanisms governing egg production. At the same time, microRNAs that regulate genes responsible for egg-laying in chickens were reviewed. 4. Research on endocrinological and genetic factors affecting egg-laying performance will greatly improve the reproductive performance of chickens and promote the protection, development, and utilisation of poultry. This review summarises studies on the endocrine and genetic factors of egg-laying performance in chickens from 1972 to 2019.

Abstract
Development of ovarian follicles requires interactions between granulosa cells, theca cells, and oocytes. Multiple transcription levels are involved but information about the role of noncoding RNAs, especially circular RNAs (circRNAs), is lacking. Here, we used RNA sequencing to profile circRNAs and mRNAs in theca cells from three types of follicle: small yellow follicles (SYF), the smallest hierarchical follicles (F6), and the largest hierarchical follicles (F1). Using bioinformatics analysis, we identified a total of 14,502 circRNAs in all theca cells, with 5622 widely distributed in all stages of development. Differential expression analysis suggested that some genes display differential isoforms during follicular development. Kyoto Encyclopedia of Genes and Genomes (KEGG) analysis revealed enrichment of both differentially expressed circRNAs and mRNAs in pathways associated with reproduction, including the TGF-β signaling pathway, oocyte meiosis, and vascular smooth muscle contraction. Our study provides the first visual information about circRNAs and mRNAs in theca cells during follicle development in chickens and adds to the growing body of knowledge about theca cells.

Abstract
Molecular breeding exploiting candidate genes is burgeoning reproductive approach to improve growth traits in poultry. The activin type IIB receptor (ACTRIIB) is a negative growth regulator, modulating action of many muscle growth regulators. PCR-single-strand conformation polymorphism was employed to unravel polymorphism in promoter region of the ACTRIIB gene and delineate its association with growth traits in Aseel and control broiler (CB). Analysis of 5' promoter region (1122bp) of ACTRIIB gene identified five SNPs, that is g. [56 G > C (SNP1), 352A > C (SNP2), 580G > A (SNP3), 625C > T (SNP4) and 962C > T (SNP5)] at SMAD, paired box 7 homeodomain binding motif, GC box and bHLH-PAS type transcription factors in CB and Aseel. CB had significantly higher body weight (BW) and average daily gain (ADG) at all SNP sites, except at SNP 1. The haplotype construction resulted 8 haplotypes in CB and Aseel population. The BW and ADG differed significantly (p < .05) at all ages in CB and Aseel. The diplotypes H1H8 and H1H4 manifested higher BW and ADG, while diplotypes H3H8 and H3H7 displayed BW and ADG at each age in both lines (p < .05). Aseel exhibited higher expression of ACTRIIB gene than CB by 70.17, 4.83, 1.41, 2.38, 5.13, 1.20, 2.90, 6.53 and 11.75 times for h1h2, h1h3, h1h4, h1h6, h1h7, h1h8 h3h4, h3h7 and h3h8, respectively. The H3H8 and H3H7 diplotypes exhibited higher level of mRNA and protein than H1H8 and H1H4. The regulatory upstream region of ACTRIIB gene demonstrates high degree of genetic diversity and can be harnessed as potential marker in genetic selection programmes for increasing meat production.
