Meta-analysis of the association between overexpression of RAD51 family genes and prognosis and clinical features in breast cancer.

The RAD51 family of genes play a crucial role in the repair of DNA damage, and increasing evidence suggests a close link between the aberrant expression of RAD51 family genes and the development of breast cancer. However, their prognostic and clinical relevance remains subjects of ongoing debate. This study aims to systematically investigate the relationship between the overexpression of RAD51 family genes and breast cancer prognosis, as well as their association with clinicopathological characteristics, through a comprehensive meta-analysis.

Low Levels of High-Density Lipoprotein are Associated With Poor Prognosis in Patients With Early Triple-Negative Breast Cancer.

Background: Although dyslipidemia has been shown to be associated with breast cancer prognosis, the prognostic value of high-density lipoprotein (HDL) in triple-negative breast cancer (TNBC) remains uncertain. The purpose of this study was to evaluate the relationship between preoperative HDL levels and prognosis in TNBC patients.

Methods: Preoperative HDL levels and clinical data from 287 patients who underwent TNBC surgery were retrospectively collected.

Sacubitril/valsartan attenuates myocardial inflammation, hypertrophy, and fibrosis in rats with heart failure with preserved ejection fraction.

Heart failure with preserved ejection fraction (HFpEF) represents a multifaceted syndrome related to complex pathologic mechanisms. Sacubitril/valsartan (Sac/val) has demonstrated therapeutic efficacy in HFpEF treatment. However, additional research is required to elucidate its pharmacological mechanisms.

Genome-wide association study reveals the genes associated with the leaf inclusion contents in Chinese medical tree Eucommia ulmoides.

Eucommia ulmoides is an economic tree that can biosynthesize secondary metabolites with pharmacological functions. Genetic basis of biosynthesis of these compounds is almost unknown. Therefore, genomic-wide association study was performed to exploit the genetic loci maybe involved in biosynthetic pathways of 5 leaf inclusions (aucubin, chlorogenic acid, gutta-percha, polyphenols, total flavonoids).

Characterization of a Protease Hyper-Productive Mutant of Bacillus pumilus by Comparative Genomic and Transcriptomic Analysis.

Bacillus pumilus BA06 has great potential for the production of alkaline proteases. To improve the protease yield, classical mutagenesis to combine the physical and chemical mutagens was performed to obtain a protease hyper-productive mutant SCU11. The full genome sequences of BA06 and SCU11 strains were assembled through DNA sequencing using the PacBio sequencing platform.

A novel DNA methylation motif identified in Bacillus pumilus BA06 and possible roles in the regulation of gene expression.

Single-molecule real-time (SMRT) sequencing can be used to identify a wide variety of chemical modifications of the genome, such as methylation. Here, we applied this approach to identify N6-methyl-adenine (m6A) and N4-methyl-cytosine (m4C) modification in the genome of Bacillus pumilus BA06. A typical methylation recognition motif of the type I restriction-modification system (R-M), 5'-TCAN8TTGG-3'/3'-AGTN8AACC-5', was identified.

Disruption of the pleiotropic gene scoC causes transcriptomic and phenotypical changes in Bacillus pumilus BA06.

Background: Bacillus pumilus is a Gram-positive and endospore-forming bacterium broadly existing in a variety of environmental niches. Because it produces and secrets many industrially useful enzymes, a lot of studies have been done to understand the underlying mechanisms. Among them, scoC was originally identified as a pleiotropic transcription factor negatively regulating protease production and sporulation in B.

Hepatocellular carcinoma with en bloc diaphragmatic resection: A single-center experience over 14 years.

Background: Diaphragmatic resection is not common in patients undergoing hepatectomy for hepatocellular carcinoma (HCC). This study aims to evaluate retrospectively the clinical characteristics and surgical results of HCC patients undergoing hepatectomy plus diaphragmatic resection.

Methods: Between January 2000 and December 2013, 52 HCC patients underwent curative resections combined with diaphragmatic resection, with 11 patients had pathological diaphragmatic invasion (DI), 41 patients had diaphragmatic fibrous adhesion (DFA).

Transcriptome profiling analysis reveals metabolic changes across various growth phases in Bacillus pumilus BA06.

Background: Bacillus pumilus can secret abundant extracellular enzymes, and may be used as a potential host for the industrial production of enzymes. It is necessary to understand the metabolic processes during cellular growth. Here, an RNA-seq based transcriptome analysis was applied to examine B.
