- Lactation curve parameters (LCP) are essential in the refinement of dairy cattle breeding programs due to their relationship with the shape of lactation curves and their biological interpretations. In this context, the primary objectives of this study were to perform genome-wide association studies and functional enrichment analyses of various LCP from random regression models based on 3 nonlinear functions (Wood [WD], Wilmink [WL], and Ali-Schaeffer [AS]) in American Holstein cattle. We used 2,754,840 and 1,642,653 daily milk yield records of 11,139 first and 6,735 s parity cows, respectively, born between 2012 and 2019. A total of 14,464 animals were also genotyped with 60,277 single nucleotide polymorphisms (SNP). The SNP effects, the proportion of the total additive genetic variance explained by them, and their approximate P-values, were estimated for the random regression coefficients based on the GBLUP method. Significant SNP were identified using a modified Bonferroni multiple testing correction that accounts for the number of independent chromosomal segments. Genes and quantitative trait loci located within 100 kb upstream or downstream of the significant SNP were then examined, and functional enrichment analyses were conducted on the candidate genes identified for each LCP. For first parity cows, 81, 128, and 196 significant SNP were identified for the WD, WL, and AS parameters, respectively; whereas for second-parity cows, 120, 125, and 128 significant SNP were identified for the same parameters. The significant SNP were located on 18 autosomal chromosomes. One genomic region (BTA14: 1,801,116 bp) was common to all the parametric functions (WD, WL, and AS). The genomic markers located on BTA15 and BTA19 were unique to the WL parameters; whereas those located on BTA3 and BTA20 were unique to the AS parameters. There were significant SNP located on BTA14 capturing more than 1% of the total additive genetic variance. Twenty candidate genes (i.e., ARC, ADGRB1, C8orf90, CYP11B1, DENND3, GML, GPR20, JRK, LY6D, LY6E, LY6L, LYNX1, LYPD2, PSCA, PTK2, PTP4A3, SLURP1, SLC45A4, THEM6, and TSNARE1) were common to all the parametric functions. No significant gene ontology terms were found for the WD parameter c (i.e., decreasing slope parameter after the lactation peak yield) for first parity cows, and for the AS parameters d and f (parameters associated with the increasing slope) for second-parity cows. Previous reports have identified candidate genes within these genomic regions that possess biological functions related to apoptotic and regulation of gene expression, milk production, clinical mastitis, milk lactose, somatic cell score, fat yield, and udder morphology. This study enabled the identification of several candidate genes associated with LCP, enhancing our understanding of the genomic architecture underlying LCP in American Holstein cattle. - Source: PubMed

Sajjad AhsanAmer RidaAlsayed MohammadButt Muhammad DaoudMandayam SreedharSajjad MobeenMasood Attique Ur Rehman - Hypertension remains the world's leading preventable cause of cardiovascular morbidity and mortality. Despite the availability of diverse antihypertensive drug classes, resistant hypertension continues to affect millions globally, leading to a disproportionate risk of stroke, heart failure, kidney disease, and premature death. Aldosterone excess is a central driver of treatment resistance, yet direct pharmacological suppression of aldosterone biosynthesis has long eluded clinical success due to the challenge of selectively targeting aldosterone synthase (CYP11B2) over its near-identical paralog 11β-hydroxylase (CYP11B1). Baxdrostat (CIN-107, RO6836191), an orally bioavailable, highly selective aldosterone synthase inhibitor (ASI), has now demonstrated robust blood pressure reduction in phase 3 clinical trials, marking a potential paradigm shift in the management of resistant hypertension. This Review summarizes the pathophysiology of aldosterone in hypertension, the molecular pharmacology of CYP11B2 inhibition, the discovery and development of Baxdrostat, and its clinical evaluation. We further discuss the broader implications of targeting steroidogenic cytochrome P450 enzymes and highlight future opportunities and challenges as Baxdrostat and related agents enter the cardiovascular pharmacopeia. - Source: PubMed

Capriello ImmaDömling Alexander - Adrenocortical carcinoma (ACC) is a rare malignancy often associated with disorganized steroid synthesis, leading to variable clinical phenotypes. Etomidate, an imidazole derivative, is a potent inhibitor of adrenal cytochrome P450-dependent enzymes, particularly 11β-hydroxylase (CYP11B1). Subhypnotic doses of etomidate are effective in reducing serum cortisol in patients with severe Cushing syndrome, a common manifestation in ACC. However, the effects of etomidate on other adrenal hormones in ACC remain poorly understood. In this report, we measured 13 steroid hormones before and after etomidate infusion using liquid chromatography-tandem mass spectrometry in a patient with ACC. Etomidate administration led to marked suppression of cortisol and aldosterone, while 11-deoxycorticosterone levels increased substantially. Interestingly, despite the elevated 11-deoxycorticosterone, serum potassium normalized, highlighting a complex interplay among mineralocorticoid precursors and active hormones in maintaining electrolyte balance. - Source: PubMed

Bhattacharya OliviaSingha ArijitNeogi SubhasisChowdhury Subhankar - Ovulation is a highly regulated inflammatory process that involves the initiation and timely resolution of the inflammation for efficient oocyte maturation. During this process, glucocorticoids accumulate in the pre-ovulatory follicular environment as an anti-inflammatory mediator. However, their temporal regulation, endogenous synthesis, and functional significance on oocyte maturation and subsequent developmental competence remain unclear. - Source: PubMed
