BioM2: biologically informed multi-stage machine learning for phenotype prediction using omics data.

Navigating the complex landscape of high-dimensional omics data with machine learning models presents a significant challenge. The integration of biological domain knowledge into these models has shown promise in creating more meaningful stratifications of predictor variables, leading to algorithms that are both more accurate and generalizable. However, the wider availability of machine learning tools capable of incorporating such biological knowledge remains limited.

Chromosome-level genome assembly provides insights into the genetic diversity, evolution, and flower development of Prunus conradinae.

Prunus conradinae, a valuable flowering cherry belonging to the Rosaceae family subgenus Cerasus and endemic to China, has high economic and ornamental value. However, a high-quality P. conradinae genome is unavailable, which hinders our understanding of its genetic relationships and phylogenesis, and ultimately, the possibility of mining of key genes for important traits.

Promoter hypermethylation-induced downregulation of ITGA7 promotes colorectal cancer proliferation and migration by activating the PI3K/AKT/NF-κB pathway.

We previously reported that integrin alpha 7 (ITGA7) was downregulated in colorectal cancer (CRC) tissues and CRC cell lines and that the lower expression of ITGA7 in CRC tissues was correlated with distant metastasis, suggesting that ITGA7 may function as a suppressor in CRC. The present research was conducted to further investigate the role and mechanisms of ITGA7 in CRC progression. First, bisulfite modification and genomic sequencing (BSP) results showed that the methylation rate of ITGA7 promoter was higher in 10 CRC tissues than in the matched normal tissues.

AHNAK2 Regulates NF-κB/MMP-9 Signaling to Promote Pancreatic Cancer Progression.

Early metastasis of pancreatic cancer (PaC) is a major cause of its high mortality rate. Previous studies have shown that AHNAK2 is involved in the progression of some tumors and is predicted to be an independent prognostic factor for PaC; however, the specific mechanisms through which AHNAK2 regulates PaC remain unclear. In this study, we examined the role of AHNAK2 in PaC and its potential molecular mechanisms.

Chromosome-scale genome assembly of provides novel insights into genome evolution, disease resistance, and dormancy release in L.

is a wild cherry germplasm resource distributed mainly in Southwest China. Despite its ornamental and economic value, a high-quality assembled genome is unavailable, hindering our understanding of its genetic background, population diversity, and evolutionary processes. Here, we assembled a chromosome-scale genome using Oxford Nanopore, Illumina, and chromosome conformation capture sequencing.

Knockdown of tankyrase 1 inhibits the progression of gastric adenocarcinoma via regulating human telomerase reverse transcriptase and telomeric repeat binding factor 1.

Background: Gastric cancer is one of the most lethal cancers. Aberrant expression levels of genes are frequently associated with cell immortalization and the occurrence of tumors. In this study, we aimed to investigate the role of tankyrase 1 () in gastric adenocarcinoma and clarify the underlying mechanism.

The Reliability and Validity of Post Stroke Depression Scale in Different Type of Post Stroke Depression Patients.

Objective: A self-rating post stroke depression scale (PSDS) showed a good reliability and validity to assess severity of depressive symptoms among stroke patients. This study aimed to retest the psychometric properties of PSDS in different types of post-stroke depression (PSD).

Materials And Methods: A total of 170 stroke patients were recruited in the study.

Effects of addition of probiotic and/or bismuth to triple therapy of H. pylori and analysis of genetic variation of 23S rRNA gene between patients with clarithromycin sensitivity and resistance.

The aim of the study was to compare the effects of three treatment regimens for H. pylori in patients sensitive to clarithromycin and analyze the polymorphism of 23S rRNA gene between patients who were sensitive or resistant to clarithromycin in a Chinese Han population. 204 H.

Development of high transferability cpSSR markers for individual identification and genetic investigation in Cupressaceae species.

Given the low substitution rate in plastomes, the polymorphic and codominant nature of chloroplast SSRs (cpSSRs) makes them ideal markers, complementing their nuclear counterpart. In Cupressaceae, cpSSRs are mostly paternally inherited, thus, they are useful in mating systems and pollen flow studies. Using e-PCR, 92 SSR loci were identified across six Cupressaceae plastomes, and primers were designed for 26 loci with potential interspecific transferability.

New opinion on the subtypes of poststroke depression in Chinese stroke survivors.

Aim: Poststroke depression (PSD) is the most common complication of stroke. However, some stroke survivors with depression cannot meet the diagnostic criteria of PSD. The aim of this study was to propose the new conception of stroke patients with depression and then make them to receive reasonable diagnosis and treatment.

[Therapeutic schemes for refractory ascites of advanced schistosomiasis: a clinical control study].

Objective: To explore the therapeutic schemes for refractory ascites of advanced schistosomiasis.

Methods: The advanced schistosomiasis patients with refractory ascites were randomly divided into 4 groups: a conventional group, high-dose albumin group, high-dose diuretic group, and comprehensive group, and the course of the treatment was 4 weeks. The abdominal circumference, urine volume, and weight changes were observed daily, and B-ultrasound, liver function, and renal function were performed weekly.

Effect of sodium on vasoconstriction and angiotensin II type 1 receptor mRNA expression in cold-induced hypertensive rats.

Angiotensin II and sodium play an important pathogenetic role in several models of hypertension. Now, we investigated the effects of sodium on vasoconstriction and angiotensin II type 1 (AT1) and type 2 (AT2) receptor mRNA expression in aortic vessels from cold-induced hypertensive rats. Wistar rats on low sodium and high sodium diet were exposed to cold-stress for 8 weeks.

Label-free hybridization detection of a single nucleotide mismatch by immobilization of molecular beacons on an agarose film.

We developed a new technique to immobilize a set of molecular beacons on an agarose film-coated slide and found that it has the ability to identify a single nucleotide difference in label-free DNA targets. The annealing properties, specificity and hybridization dynamics of the present technique were compared with those of the conventional technique that directly immobilizes molecular beacons on a planar glass slide. It is demonstrated that the molecular beacon array on an agarose film has high quench efficiency, an excellent discrimination ratio for single nucleotide mismatches and a short detection time.

Endothelial dysfunction in cold-induced hypertensive rats.

Endothelial dysfunction can be observed in preatherosclerotic conditions. However, its pathogenetic role in hypertension is still controversial. Endothelial-dependent changes of blood pressure (BP) and expression of endothelial nitric oxide synthase (eNOS) were evaluated in cold-induced hypertensive rats.
