Risk of Sperm Disorders and Impaired Fertility in Frozen-Thawed Bull Semen: A Genome-Wide Association Study. Animals (Basel) 2024; 14:251. [PMID: 38254422 PMCID: PMC10812825 DOI: 10.3390/ani14020251] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/16/2023] [Revised: 01/08/2024] [Accepted: 01/11/2024] [Indexed: 01/24/2024] Open
Abstract
Cryopreservation is a widely used method of semen conservation in animal breeding programs. This process, however, can have a detrimental effect on sperm quality, especially in terms of its morphology. The resultant sperm disorders raise the risk of reduced sperm fertilizing ability, which poses a serious threat to the long-term efficacy of livestock reproduction and breeding. Understanding the genetic factors underlying these effects is critical for maintaining sperm quality during cryopreservation, and for animal fertility in general. In this regard, we performed a genome-wide association study to identify genomic regions associated with various cryopreservation sperm abnormalities in Holstein cattle, using single nucleotide polymorphism (SNP) markers via a high-density genotyping assay. Our analysis revealed a significant association of specific SNPs and candidate genes with absence of acrosomes, damaged cell necks and tails, as well as wrinkled acrosomes and decreased motility of cryopreserved sperm. As a result, we identified candidate genes such as POU6F2, LPCAT4, DPYD, SLC39A12 and CACNB2, as well as microRNAs (bta-mir-137 and bta-mir-2420) that may play a critical role in sperm morphology and disorders. These findings provide crucial information on the molecular mechanisms underlying acrosome integrity, motility, head abnormalities and damaged cell necks and tails of sperm after cryopreservation. Further studies with larger sample sizes, genome-wide coverage and functional validation are needed to explore causal variants in more detail, thereby elucidating the mechanisms mediating these effects. Overall, our results contribute to the understanding of genetic architecture in cryopreserved semen quality and disorders in bulls, laying the foundation for improved animal reproduction and breeding.

Abstract
BACKGROUND Many patients with rheumatoid arthritis (RA) achieve disease remission with modern treatment strategies. However, having achieved this state, there are no tests that predict when withdrawal of therapy will result in drug-free remission rather than flare. We aimed to identify predictors of drug-free remission in RA. METHODS The Biomarkers of Remission in Rheumatoid Arthritis (BioRRA) Study was a unique, prospective, interventional cohort study of complete and abrupt cessation of conventional synthetic disease-modifying anti-rheumatic drugs (DMARDs). Patients with RA of at least 12 months duration and in clinical and ultrasound remission discontinued DMARDs and were monitored for six months. The primary outcome was time-to-flare, defined as disease activity score in 28 joints with C-reactive protein (DAS28-CRP) ≥ 2.4. Baseline clinical and ultrasound measures, circulating inflammatory biomarkers, and peripheral CD4+ T cell gene expression were assessed for their ability to predict time-to-flare and flare/remission status by Cox regression and receiver-operating characteristic (ROC) analysis respectively. RESULTS 23/44 (52%) eligible patients experienced an arthritis flare after a median (IQR) of 48 (31.5-86.5) days following DMARD cessation. A composite score incorporating five baseline variables (three transcripts [FAM102B, ENSG00000228010, ENSG00000227070], one cytokine [interleukin-27], one clinical [Boolean remission]) differentiated future flare from drug-free remission with an area under the ROC curve of 0.96 (95% CI 0.91-1.00), sensitivity 0.91 (0.78-1.00) and specificity 0.95 (0.84-1.00). CONCLUSION We provide proof-of-concept evidence for predictors of drug-free remission in RA. If validated, these biomarkers could help to personalize immunosuppressant withdrawal: a therapy paradigm shift with ensuing patient and economic benefits.

Abstract
Although most neural tube defects (anencephaly, spina bifida) occur as isolated malformations, a substantial proportion are attributable to chromosome anomalies, known teratogens, or component manifestations of multiple anomaly syndromes. This review describes known chromosome alterations and the candidate genes residing in the altered region, as well as syndromes associated with neural tube defects and causative genes, if known.

Abstract
Cytogenetic studies of two patients with acute myeloblastic leukemia, classified as M1 and M2, showed a partial duplication of the distal part of the long arm of chromosome 12 (12q24) as the sole detectable chromosome abnormality. High white blood cell count was common to the two leukemic children. Fluorescence in situ hybridization analysis with the use of a whole-chromosome 12 painting probe and a telomeric probe confirmed the apparent absence of any translocation. The genes involved in the duplication could not be ascertained, but several candidate genes such as growth-factor receptors or genes encoding transcription factors localized to 12q22-q24 should be investigated in the molecular analysis of these duplications.

Abstract
Holt-Oram syndrome (HOS) is an autosomal dominant condition of unknown origin characterized by congenital septal heart defects with associated malformations of the upper limbs (radial ray). Here, we report on the mapping of a gene causing HOS to the distal long arm of chromosome 12 (12q21-qter) by linkage analysis in nine informative families (Zmax = 6.81 at theta = 0 at the D12S354 locus). Also, multipoint linkage analysis places the HOS gene within the genetic interval between D12S84 and D12S79 (multipoint lod-score in log base 10 = 8.10). The mapping of a gene for HOS is, to our knowledge, the first chromosomal localization of a gene responsible for congenital septal heart defect in human. The characterization of the HOS gene will hopefully shed light on the molecular mechanisms that govern heart septation in the early stages of embryogenesis.

Abstract
Nine KOX zinc finger genes were localized on four human chromosomes by in situ hybridization of cDNA probes to metaphase chromosomes. KOX1 (ZNF10), KOX11 (ZNF18), and KOX12 (ZNF19) were mapped to chromosome bands 12q24.33, 17p13-p12, and 16q22-q23, respectively. Six other KOX genes were localized on chromosome 19: KOX6 (ZNF14) and KOX13 (ZNF20) to 19p13.3-p13.2, KOX5 (ZNF13) and KOX22 (ZNF27) to 19q13.2-qter, and KOX24 (ZNF28) and KOX28 (ZNF30) to 19q13.4. Pulsed field gel electrophoresis experiments showed that the pairs of KOX genes found on the chromosome bands 12q24.33, 16q22-q23, 19p13.3-p13.2, or 19q13.3-qter lie within 200-300 kb DNA fragments. This suggests the existence of KOX gene clusters on these chromosomal bands.

Abstract
Two members of the KOX gene family, ZNF23 (KOX16) and ZNF32 (KOX30), have been mapped by in situ hybridization to chromosome regions 16q22 and 10q23-q24, respectively. The map location of ZNF23 and ZNF32 placed these zinc finger protein genes near to chromosome loci that, under certain in vitro conditions, are expressed as fragile sites (FRA16B, FRA16C) and (FRA10D, FRA10A, FRA10B and FRA10E). Human zinc finger gene ZNF32 maps to a chromosome region on 10q23-24 in which deletions have been observed associated with malignant lymphoma on 10q22-23 and with carcinoma of the prostate on 10q24. ZNF23 is located on 16q22 in a chromosomal region that has been involved in chromosome alterations characteristic of acute myeloid leukemia. A second Kox zinc finger gene (ZNF19/KOX12) was recently mapped to the same chromosome region on human chromosome 16q22. In the analogous murine position, the murine zinc finger genes Zfp-1 and Zfp-4 are found in the syntenic 16q region of mouse chromosome 8. Thus, ZNF19 and ZNF23 might be members of an evolutionarily conserved zinc finger gene cluster located on human chromosome 16q22.

Abstract
Two related zinc finger (ZNF) gene clusters from the pericentromeric region of human chromosome 10, defined by cDNAs of the KOX series, have been cloned in yeast artificial chromosomes (YACs). The two clusters evolved by duplication of an ancestral gene cluster before the divergence of the human and great ape lineages. Included in cluster A are the ZNF gene sequences ZNF11A, ZNF33A, and ZNF37A, while cluster B comprises the related sequences ZNF11B, ZNF33B and ZNF37B. Genes from both clusters are expressed: cDNAs KOX2, KOX31 and KOX21 derive from ZNF11B, ZNF33A and ZNF37A, respectively. Further YACs have been isolated which link ZNF11A and ZNF33A to another gene, ZNF25, defined by cDNA clone KOX19. Therefore ZNF25 also forms part of cluster A, but has no counterpart in cluster B. Surprisingly, the KOX ZNF gene clusters are located on opposite sides of the centromere: cluster A maps to 10p11.2, while cluster B is in 10q11.2. This suggests the occurrence during primate evolution of a previously undescribed pericentric inversion subsequent to the cluster duplication. The evolution of this subset of KOX ZNF genes has therefore involved three types of genetic event: local gene duplication, gene cluster duplication, and chromosome rearrangement.

Abstract
Craniosynostosis or premature closure of the cranial sutures is a common abnormality occurring in about 1 in 2500 children. There is evidence of mendelian inheritance in some 20% of cases. Published reports of patients with structural alterations of the short arm of chromosome 7 have suggested that two or more genes for craniosynostosis may be situated in this region. The Saethre-Chotzen syndrome (acrocephalosyndactyly type III) is one of the most common autosomal dominant craniosynostosis syndromes. Results of molecular genetic linkage studies provide evidence for localisation of the gene responsible to distal chromosome 7p.

Abstract
Three members of the human zinc finger Krüppel family, ZNF11/KOX2, ZNF22/KOX15, and ZNF25/KOX19, have been regionally localized to the pericentromeric region of chromosome 10 by in situ chromosomal hybridization and somatic cell hybrid analysis. ZNF25/KOX19 is located centromeric to a breakpoint in chromosome band 10q11.2 in the chromosome region 10p11.2-q11.2, whereas ZNF22/KOX15 maps distal to it in band 10q11.2. Sequences hybridizing to the KOX2 probe are found at two loci, ZNF11A and ZNF11B, that map proximal and distal to the 10q11.2 breakpoint, respectively. The two ZNF11 loci probably represent two related sequences in 10p11.2-q11.2. This cluster of ZNF/KOX genes is of particular interest since the loci for multiple endocrine neoplasia type 2A and 2B (MEN2A and MEN2B) syndromes have been assigned to this region by linkage analysis.
