MreB: unraveling the molecular mechanisms of bacterial shape, division, and environmental adaptation.

As a key bacterial actin-like protein, MreB plays crucial roles in maintaining cell shape, regulating peptidoglycan synthesis, and coordinating chromosome segregation, making it a promising target for novel antibiotics. This review comprehensively explores MreB’s molecular architecture, its assembly into antiparallel protofilaments, and its pivotal roles in bacterial cell morphology and division. We also delve into how MreB interacts with membrane-associated proteins such as RodZ and MreC/D to coordinate cell wall synthesis and respond to environmental signals like ion gradients and temperature changes.

An RFH-NPT-based nomogram for predicting the long-term survival of liver cirrhosis patients: a multicenter study.

Background And Aims: The Royal Free Hospital-Nutritional Prioritizing Tool (RFH-NPT) identifies nutritional risk in patients with liver disease, an important factor in cirrhosis outcomes. Recognizing the gap in existing prognostic models, which often overlook malnutrition, we developed and validated an RFH-NPT-based model for predicting outcomes of patients with cirrhosis.

Methods: This study included inpatients with cirrhosis from a single center between February and July 2016 (training cohort) and patients from six other medical centers admitted between December 2011 and May 2022 (validation cohort).

Host SUMOylation in bacterial infections and immune defense mechanisms.

SUMOylation, the covalent attachment of small ubiquitin-like modifier proteins (SUMO) to lysine residues of target substrates, has emerged as a crucial post-translational modification regulating various cellular processes. Recent studies have revealed that SUMOylation also plays significant roles in host-pathogen interactions during bacterial infections. On the one hand, SUMOylation can modulate host innate immune responses, such as inflammatory signaling and autophagy, to defend against invading bacteria.

We conducted a case-control study, including 248 patients with SZ and 236 healthy controls matched for age and sex. The Mass-array platform was used to detect all the genotypes of the SNPs.

The significance of m6A RNA methylation regulators in diagnosis and subtype classification of HBV-related hepatocellular carcinoma.

In recent years, abnormal m6A alteration in hepatocellular carcinoma (HCC) has been a focus on investigating the biological implications. In this study, our objective is to determine whether m6A modification contributes to the progression of HBV-related HCC. To achieve this, we employed a random forest model to screen top 8 characteristic m6A regulators from 19 candidate genes.

Interaction analysis of hydrochemical factors and dissolved heavy metals in the karst Caohai Wetland based on PHREEQC, cooccurrence network and redundancy analyses.

In this study, to clarify the interaction between dissolved heavy metals and the coexisting chemical factors in karst wetland waters, surface water samples were collected from the Caohai Wetland during a water year, and the hydrochemistry and heavy metal pollution characteristics of the samples were analyzed. The main influencing factors of heavy metals in different water periods were identified through a cooccurrence network analysis. To further analyze the influence mechanism of these main influencing factors, the forms of heavy metals in the water were simulated with PHREEQC software, and the effects of these main influencing factors on the forms were analyzed by redundancy analysis.

Phosphorus sorption - Desorption behaviors in the sediments cultured with Hydrilla verticillata and Scripus triqueter as revealed by phosphorus fraction and dissolved organic matter.

The migration of sediment phosphorus (P) could be affected by the existence of aquatic plants. To explore the effects of aquatic plants on the P sorption-desorption behaviors in the sediments, sediment in Caohai wetland was collected and cultured with the submerged plant (Hydrilla verticillata) and emerged plant (Scripus triqueter). Then the sorption and desorption experiments were performed, and physicochemical properties, P fractions, and dissolved organic matter (DOM) characteristics were evaluated.

YTHDF1 Facilitates the Progression of Hepatocellular Carcinoma by Promoting FZD5 mRNA Translation in an m6A-Dependent Manner.

Hepatocellular carcinoma (HCC), one of the most aggressive malignancies, ranks as the fourth leading cause of cancer-related deaths worldwide. Emerging evidence indicates that RNA N6-methyladenosine (m6A) plays a critical role in tumor progression. However, the biological function of YTHDF1 in HCC remains unclear.

Influence of different land use types on hydrochemistry and heavy metals in surface water in the lakeshore zone of the Caohai wetland, China.

In recent years, with the expansion of the Weining county in the northeast of Caohai wetland, the construction of a new port in the north, and the large-scale development of cultivated land in the east, land use patterns in lakeshore areas have changed. These changes have affected the state of lake shores water bodies in complex ways, resulting in varying degrees of local water pollution. To explore the distribution and transformation characteristics of water chemistry and heavy metals in different areas of a water body under the influence of different land uses, especially the interactions between water chemical factors and heavy metals in different areas of a water body, this study used Circos diagrams, originally used in biological genetic analysis, to visualize these interactions.

Exosomal lncRNA 91H is associated with poor development in colorectal cancer by modifying HNRNPK expression.

Background: Exosomes mediated transfer of lncRNA 91H may play a critical role in the development of CRC. However, few studies have proved the mechanism. So we performed this study to deeply explore the biological functions of exosomal 91H in the development and progression of CRC.

Association of the DISC1 and NRG1 genetic polymorphisms with schizophrenia in a Chinese population.

Polymorphisms in Disrupted-in-Schizophrenia 1 (DISC1) and Neuregulin 1 (NRG1) might be associated with schizophrenia; however, the conclusions of relevant studies were inconsistent across different ethnic populations. This population-based case-control study was carried out to determine whether polymorphisms in these two genes could be associated with schizophrenia in the Chinese population. A case-control study of 248 schizophrenia patients and 236 controls was performed with the Sequenom MassARRAY platform.
