Downregulation of ST3GAL5 is associated with muscle invasion, high grade and a poor prognosis in patients with bladder cancer.

In patients with bladder cancer (BC), the association between ST3 β-galactoside α-2,3-sialyltransferase 5 (ST3GAL5) expression and clinical outcomes, particularly regarding muscle-invasive disease, high tumor grade and prognosis, remain unknown. In the present study, the expression of ST3GAL5 and its association with clinical outcomes in patients with BC was analyzed using various public bioinformatics databases. The difference in ST3GAL5 expression between BC and healthy bladder tissues was also evaluated using data from the Oncomine database, The Cancer Genome Atlas and Gene Expression Omnibus database.

ORF4 of the Temperate Archaeal Virus SNJ1 Governs the Lysis-Lysogeny Switch and Superinfection Immunity.

Recent environmental and metagenomic studies have considerably increased the repertoire of archaeal viruses and suggested that they play important roles in nutrient cycling in the biosphere. However, very little is known about how they regulate their life cycles and interact with their hosts. Here, we report that the life cycle of the temperate haloarchaeal virus SNJ1 is controlled by the product ORF4, a small protein belonging to the antitoxin MazE superfamily.

LINC00152 promotes pancreatic cancer cell proliferation, migration and invasion via targeting miR-150.

Pancreatic cancer (PC) is one of the top deaths causing cancers with low 5-year survival rate. Long non-coding RNAs (lncRNAs) are recognized as a crucial type of nonprotein-coding transcripts implicated in tumorigenesis. Emerging evidence has implied that LINC00152 exerts the potential oncogenic functions in various cancers.

Mechanism underlying the regulation of sortilin expression and its trafficking function.

This review summarizes and analyzes the updated information on the regulation of sortilin expression and its trafficking function. Evidence indicates that the expression and function of sortilin are closely regulated at four levels: DNA, messenger RNA (mRNA), protein, and trafficking function. DNA methylation, several mutations, and minor single-nucleotide polymorphisms within DNA fragments affect the expression of SORT1 gene.

Emerging role of Insig-1 in lipid metabolism and lipid disorders.

Growing evidence has demonstrated that Insig-1 is intricately involved in lipid metabolism regulation and the progression of lipid disorders. Our review summarizes updated information on the role and underlying mechanisms of Insig-1 in lipid metabolism dyshomeostasis and lipid disorders. As a member of the insulin-induced gene family, insulin-induced gene 1 (Insig-1) is a six-span transmembrane protein embedded in the endoplasmic reticulum (ER) membrane.

Effects of tree species richness on fine root production varied with stand density and soil nutrients in subtropical forests.

Fine root production accounts for a large proportion of net primary production (NPP) in forest ecosystems that is highly responsive to environmental and biotic changes. The underlying mechanisms of the relationship between tree species richness and fine root production have not been fully examined. Here we hypothesized that: (i) the relationship between aboveground species richness and fine root production could be attributable to belowground spatial resource partitioning; (ii) either symmetrical or asymmetrical root proliferation to obtain nutrients leads to increased fine root production; and (iii) stand density affects the relationship between species richness and fine root production.

Longitudinal Association Between Markers of Liver Injury and Mortality in COVID-19 in China.

Background And Aims: Coronavirus disease 2019 (COVID-19) is a new infectious disease. To reveal the hepatic injury related to this disease and its clinical significance, we conducted a multicenter retrospective cohort study that included 5,771 adult patients with COVID-19 pneumonia in Hubei Province.

Approach And Results: We reported the distributional and temporal patterns of liver injury indicators in these patients and determined their associated factors and death risk.

Graphene oxide nanosheets mitigate the developmental toxicity of TDCIPP in zebrafish via activating the mitochondrial respiratory chain and energy metabolism.

Graphene oxide (GO), a novel two-dimension carbon nanomaterial, has showed tremendous potential for utilization in intelligent manufacturing and environmental protection. In parallel, tris(1,3-dichloro-2-propyl) phosphate (TDCIPP) is widely distributed in the water environment and represents a great threat to ecosystem health. However, the related knowledge remained absent regarding the impact of GO on the biological risks of TDCIPP.

Modulation of an intermediate layer between NiCoP and Ni foam substrate in a microwire array electrode for enhancing the hydrogen-evolution reaction.

A hierarchical electrode consisting of a Ni foam substrate, an intermediate layer of a Mo-doped basic cobalt carbonate microwire array, and a surface layer of NiCoP was fabricated for hydrogen evolution. The introduction of the intermediate layer accounted for the low overpotential (45 mV, 10 mA cm) and high solar-to-hydrogen conversion efficiency (14.9%) in a PEC water splitting application.

Characterizing the gut microbiota in patients with chronic kidney disease.

: Emerging evidence suggests that gut microbiota dysbiosis plays a critical role in chronic kidney disease (CKD). However, the relationship between altered gut microbiome profiles and disease severity remains unclear. In this study, we sought to characterize the gut microbiota in CKD patients compared to healthy controls, and to explore potential relationships between gut microbiota composition and disease severity.

CLIPPERS, a syndrome of lymphohistiocytic disorders.

Background: CLIPPERS (chronic lymphocytic inflammation with pontine perivascular enhancement responsive to steroids) is a chronic central nervous system (CNS) inflammatory disorder. It may be associated with lymphoma and macrophage activation, while the related report of histiocytes (macrophage) activation involved in pathogenesis of CLIPPERS is rare. We present the first "probable CLIPPERS" case associated with histiocytic sarcoma (HS) progressed to hemophagocytic syndrome (HPS) in a 38-year-old man patient.

Regulation of cGAS-Mediated Immune Responses and Immunotherapy.

Early detection of infectious nucleic acids released from invading pathogens by the innate immune system is critical for immune defense. Detection of these nucleic acids by host immune sensors and regulation of DNA sensing pathways have been significant interests in the past years.

Cryo-EM structures of the human PA200 and PA200-20S complex reveal regulation of proteasome gate opening and two PA200 apertures.

Proteasomes are highly abundant and conserved protease complexes that eliminate unwanted proteins in the cells. As a single-chain ATP-independent nuclear proteasome activator, proteasome activator 200 (PA200) associates with 20S core particle to form proteasome complex that catalyzes polyubiquitin-independent degradation of acetylated histones, thus playing a pivotal role in DNA repair and spermatogenesis. Here, we present cryo-electron microscopy (cryo-EM) structures of the human PA200-20S complex and PA200 at 2.
