P-, E-, and H-cadherins differ in their relationships with coronary stenosis, cardiovascular outcomes, and unplanned recurrent revascularization.

Background And Aims: Cadherins are adhesion proteins, and their dysregulation may result in the development of atherosclerosis, plaque rupture, or lesions of the vascular wall. The aim of the present study was to detect the associations of cadherins-P, -E, and -H, with atherosclerosis and pathological cardiovascular conditions.

Methods And Results: The present study with 3-year follow up evaluated atherosclerosis and fasting levels of P-, E-, and H-cadherins in the serum samples of 214 patients in a hospital setting.

Polygenic score distribution differences across European ancestry populations: implications for breast cancer risk prediction.

Background: The 313-variant polygenic risk score (PRS) provides a promising tool for clinical breast cancer risk prediction. However, evaluation of the PRS across different European populations which could influence risk estimation has not been performed.

Methods: We explored the distribution of PRS across European populations using genotype data from 94,072 females without breast cancer diagnosis, of European-ancestry from 21 countries participating in the Breast Cancer Association Consortium (BCAC) and 223,316 females without breast cancer diagnosis from the UK Biobank.

: Placental cadherin (CDH3) is an adhesion molecule expressed in many malignant tumors. The role of serum CDH3 in atherosclerosis is unclear. : This 3-year follow-up study measured atherosclerosis and serum CDH3 in 218 angiography inpatients.

Synonymous variants: the common denominator in adapting to ionizing radiation.

Ionizing radiation (IR) in high doses is generally lethal to most organisms. Investigating mechanisms of radiation resistance is crucial for gaining insights into the underlying cellular responses and understanding the damaging effects of IR. In this study, we conducted a comprehensive analysis of sequencing data from an evolutionary experiment aimed at understanding the genetic adaptations to ionizing radiation in .

Expression of exploratory activity of rat offspring depends on the expression of exploratory activity of their parents at the moment of mating.

The aim of this work was to study the, so far, unexplored possibility that non-genetic inheritance of animal behavioral characteristics could depend on the state of the parents at the time of conception. In this study, we measured the levels of motor and exploratory activity in rats at the ages of 2 and 5 months. Male and female rats were mated at the age of 5 months.

Atrial fibrillation recurrence after catheter ablation is associated with RAD51 and p63 proteins.

Catheter ablation has been demonstrated to reduce atrial fibrillation (AF) recurrence. The mechanisms of AF recurrence after catheter ablation are unknown, and the present study aimed to identify serum proteins associated with AF recurrence. The present prospective study comprised a cohort of patients with AF, which was divided into two groups after one-year follow-up: group 1 included patients with compensated AF after catheter ablation and group 2 included patients with AF recurrence after catheter ablation.

Integrative multi-omics analyses to identify the genetic and functional mechanisms underlying ovarian cancer risk regions.

To identify credible causal risk variants (CCVs) associated with different histotypes of epithelial ovarian cancer (EOC), we performed genome-wide association analysis for 470,825 genotyped and 10,163,797 imputed SNPs in 25,981 EOC cases and 105,724 controls of European origin. We identified five histotype-specific EOC risk regions (p value <5 × 10) and confirmed previously reported associations for 27 risk regions. Conditional analyses identified an additional 11 signals independent of the primary signal at six risk regions (p value <10).

Efficiency of moderately hypofractionated radiotherapy in NSCLC cell model.

Background: The current standard of radiotherapy for inoperable locally advanced NSCLCs with single fraction doses of 2.0 Gy, results in poor outcomes. Several fractionation schedules have been explored that developed over the past decades to increasingly more hypofractionated treatments.

Large-scale genome-wide association study of 398,238 women unveils seven novel loci associated with high-grade serous epithelial ovarian cancer risk.

Background: Nineteen genomic regions have been associated with high-grade serous ovarian cancer (HGSOC). We used data from the Ovarian Cancer Association Consortium (OCAC), Consortium of Investigators of Modifiers of (CIMBA), UK Biobank (UKBB), and FinnGen to identify novel HGSOC susceptibility loci and develop polygenic scores (PGS).

Methods: We analyzed >22 million variants for 398,238 women.

Differences in polygenic score distributions in European ancestry populations: implications for breast cancer risk prediction.

The 313-variant polygenic risk score (PRS) provides a promising tool for breast cancer risk prediction. However, evaluation of the PRS across different European populations which could influence risk estimation has not been performed. Here, we explored the distribution of PRS across European populations using genotype data from 94,072 females without breast cancer, of European-ancestry from 21 countries participating in the Breast Cancer Association Consortium (BCAC) and 225,105 female participants from the UK Biobank.

Key structural factors and intermolecular interactions underlying the formation, functional properties and behaviour in the gastrointestinal tract of the liposomal form of nutraceuticals coated with whey proteins and chitosan.

The aim of this study was to gain a better understanding of the key structural factors and intermolecular interactions underlying the formation, functionality, and gastrointestinal behaviour of the liposomal form of nutraceuticals coated with whey proteins (WPI) and chitosan (CHIT). Phosphatidylcholine (PC) liposomes were used to encapsulate a combination of hydrophobic and hydrophilic nutraceuticals. The hydrophobic constituents were long-chain (LC) n-3 PUFAs (DHA and EPA) from fish oil (FO), vitamin D3, and clove essential oil (CEO), while the hydrophilic component was γ-aminobutyric acid (GABA).

Influence of a Nitric Oxide Synthase Inhibitor on the Anxiolytic, Stimulating, and Analgesic Effects of Long-Term Perinatal Caffeine Exposure in Rats.

We studied the effect of inducible NO synthase (iNOS) inhibitor aminoguanidine on the behavioral effects of chronic perinatal caffeine exposure. Administration of caffeine in the prenatal and early postnatal periods led to the development of anxiolytic, stimulating, and analgesic effects. Administration of aminoguanidine attenuated the anxiolytic and stimulating effects and potentiated the analgesic effect of perinatal administration of caffeine.

Understanding the genetic complexity of puberty timing across the allele frequency spectrum.

Pubertal timing varies considerably and has been associated with a range of health outcomes in later life. To elucidate the underlying biological mechanisms, we performed multi-ancestry genetic analyses in ~800,000 women, identifying 1,080 independent signals associated with age at menarche. Collectively these loci explained 11% of the trait variance in an independent sample, with women at the top and bottom 1% of polygenic risk exhibiting a ~11 and ~14-fold higher risk of delayed and precocious pubertal development, respectively.

Targeted next-generation sequencing of 21 candidate genes in hereditary ovarian cancer patients from the Republic of Bashkortostan.

About 5-10% of all ovarian cancer cases show familial clustering, and some 15-25% of familial ovarian cancer cases are mediated by high-penetrance mutations in the BRCA1 and BRCA2 genes. Only few other genes have been identified for familial ovarian cancer.We conducted targeted next-generation sequencing of the protein coding region of 21 candidate genes, including UTR regions, in genomic DNA samples of 48 patients with familial ovarian cancer from the Republic of Bashkortostan.
