Abstract
Chronic obstructive pulmonary disease (COPD) is characterized by airflow limitation, respiratory symptoms, inflammation of the airways, and systemic manifestations of the disease. Genetic susceptibility and environmental factors are important in the development of the disease, particularly exposure to cigarette smoke which is the most notable risk factor. Mutations in the cystic fibrosis transmembrane conductance regulator (CFTR) gene are the cause of cystic fibrosis (CF), which shares several pathophysiological pulmonary features with COPD, including airway obstruction, chronic airway inflammation and bacterial colonization; in addition, both diseases also present systemic defects leading to comorbidities such as pancreatic, gastrointestinal, and bone-related diseases. In patients with COPD, systemic CFTR dysfunction can be acquired by cigarette smoking, inflammation, and infection. This dysfunction is, on average, about half of that found in CF. Herein we review the literature focusing on acquired CFTR dysfunction and the potential role in the pathogenesis of comorbidities associated with COPD and chronic bronchitis.

Candidate Genes in Bull Semen Production Traits: An Information Approach Review. Vet Sci 2022; 9:vetsci9040155. [PMID: 35448653 PMCID: PMC9028852 DOI: 10.3390/vetsci9040155] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/02/2022] [Revised: 03/05/2022] [Accepted: 03/15/2022] [Indexed: 02/05/2023] Open
Abstract
Semen quality plays a crucial role in the successful implementation of breeding programs, especially where artificial insemination (AI) is practiced. Bulls with good semen traits have good fertility and can produce a volume of high semen per ejaculation. The aim of this review is to use an information approach to highlight candidate genes and their relation to bull semen production traits. The use of genome-wide association studies (GWAS) has been demonstrated to be successful in identifying genomic regions and individual variations associated with production traits. Studies have reported over 40 genes associated with semen traits using Illumina BeadChip single-nucleotide polymorphism (SNPs).

Li Q, Shen Y, Zhao LJ, Wang JB, Huang X. Mutations in CFTR genes are associated with oligoasthenospermia in infertile men undergoing IVF. Andrologia 2021; 54:e14355. [PMID: 34931337 DOI: 10.1111/and.14355] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/11/2021] [Revised: 12/05/2021] [Accepted: 12/07/2021] [Indexed: 11/29/2022] Open
Abstract
Cystic fibrosis transmembrane conductance regulator (CFTR) gene mutation has been clearly defined in congenital absence of the vas deferens (CAVD), which is an important cause of obstructive azoospermia. However, the association between oligoasthenospermia and CFTR gene mutation remains controversial. To confirm this issue, 151 infertile Chinese men were screened for CFTR mutation by NGS approach, including 18 CAVD patients, 72 patients with severe oligoasthenospermia and 61 controls with normal sperm parameters. Frequency of mutation in exons of CFTR gene were 66.7% in CAVD patients (12/18) (p < 0.001) and 8.33% in severe oligoasthenospermic patients (6/72) (p < 0.05), both of which were significantly more frequent than that in the controls (0/61). In terms of introns mutation of CFTR gene, there was no significant difference in frequency of 5T between oligoasthenospermic men (5/144, 3.47%) and the controls (4/122, 3.28%) (p = 0.645). In addition, 6 novel mutations in exons of CFTR gene in this study (c.3736A>G, c.635T>G, c.482delA, c.1858C>T, c.2042A>T, c.1586A>C) have not been reported in the Cystic Fibrosis Mutation Database before. Thus, our study provides evidence that CFTR gene mutation may be the aetiology of severe oligoasthenospermia other than CAVD. It may be necessary to screen for CFTR mutations in men with severe oligoasthenospermia before receiving assisted reproductive technology.

Abstract
People with Cystic fibrosis (pwCF) have experienced increased survival and wellbeing in recent decades, such that more than half of those living with CF are adults. Consequently, sexual and reproductive health is increasingly important for pwCF as many are considering parenthood. Most men and some women with CF (wwCF) will have reduced fertility, which in both sexes is multifactorial. However, unplanned pregnancies in women are not rare, and contraception and its interaction with CF complications need to be addressed by the CF team. Reduced fertility may be overcome in most pwCF through use of assisted reproductive technologies; however, the risk of having offspring with CF must be considered. Most wwCF will have normal pregnancies, but premature birth is common especially in the setting of reduced lung function and CF related diabetes (CFRD); optimization of treatment is recommended during pregnancy planning. Parenting imposes an increased burden on pwCF, with the challenges of caring for the newborn, postpartum physiologic changes and maintaining CF treatments. Most drugs used to treat CF are considered safe in pregnancy and lactation, but exceptions need to be acknowledged, including the limited data regarding safety of CF transmembrane conductance regulator (CFTR) modulators during conception, pregnancy, and lactation. As most pwCF are eligible for highly effective CFTR modulators, fertility, contraception, and pregnancy in people with CF is changing. Prospective studies regarding these issues in people treated with CFTR modulators are paramount to provide evidence-based guidance for management in the current era of CF care.

Sun PB, Xu HM, Li K, Li HC, Chen AJ, Chen MJ, Dai HT, Ni Y. Sperm cystic fibrosis transmembrane conductance regulator expression level is relevant to fecundity of healthy couples. Andrologia 2017; 50.

Abstract
Cystic fibrosis transmembrane conductance regulator (CFTR) is relevant to sperm quality, sperm capacitation and male fertility. However, it is still unknown whether CFTR can be a potential parameter for fecundity prediction in healthy couples. In this study, 135 healthy couples were divided into groups according to their fertility. We demonstrated that the sperm CFTR expression level of healthy males who never impregnated their partners (49 cases, 38.68 ± 2.71%) was significantly lower than that of fertile men (86 cases, 46.35 ± 2.32%). Sperm CFTR expression level accurately corresponded with fertility through the logistic regression model. Receiver operating characteristic (ROC) curve analysis showed that the cut-off value of sperm CFTR expression level for fecundity prediction was 43.75%. Furthermore, cumulative pregnancy rates (CPRs) of CFTR > 43.75% group and CFTR ≤ 43.75% group during the follow-up periods were 80.6% and 49.3% respectively. Meanwhile, the mean time to pregnancy (TTP) of CFTR ≤ 43.75% group (26.79 ± 2.35) was significantly longer than that of CFTR > 43.75% group (16.46 ± 2.42). Therefore, sperm CFTR expression level is relevant to fecundity of healthy couples and shows potential predictive capacity of fecundity.

Abstract
Despite its apparently simple genetics, cystic fibrosis (CF) is a rather complex genetic disease. A lot of variability in the steps of the path from the cystic fibrosis transmembrane conductance regulator (CFTR) gene to the clinical manifestations originates an uncertain genotype - phenotype relationship. A major determinant of this uncertainty is the incomplete knowledge of the CFTR mutated genotypes, due to the high number of CFTR mutations and to the higher number of their combinations in trans and in cis. Also the very limited knowledge of functional effects of CFTR mutated alleles severely impairs our diagnostic and prognostic ability. The final phenotypic modulation exerted by CFTR modifier genes and interactome further complicates the framework. The next generation sequencing approach is a rapid, low-cost and high-throughput tool that allows a near complete structural characterization of CFTR mutated genotypes, as well as of genotypes of several other genes cooperating to the final CF clinical manifestations. This powerful method perfectly complements the new personalized therapeutic approach for CF. Drugs active on specific CFTR mutational classes are already available for CF patients or are in phase 3 trials. A complete genetic characterization has been becoming crucial for a correct personalized therapy. However, the need of a functional classification of each CFTR mutation potently arises. Future big efforts towards an ever more detailed knowledge of both structural and functional CFTR defects, coupled to parallel personalized therapeutic interventions decisive for CF cure can be foreseen.
