Sequestration of ribosomal subunits as inactive 80S by targeting eIF6 limits mitotic exit and cancer progression.

Moderating the pool of active ribosomal subunits is critical for maintaining global translation rates. A factor crucial for modulating the 60S ribosomal subunit is eukaryotic translation initiation factor-6 (eIF6). Release of eIF6 from the 60S subunit is essential to permit 60S interactions with the 40S subunit.

Neural oscillations and memory: unraveling the mechanisms of anesthesia-induced amnesia.

General anesthesia is a widely used medical practice, affecting more than 300 million patients annually. Despite its ubiquity, the underlying mechanisms through which anesthetic agents induce amnesia remain poorly understood. This review explores the impact of general anesthetics on memory function, with a particular focus on the role of neural oscillations in anesthesia-induced memory suppression.

The translation initiation factor homolog eif4e1c regulates cardiomyocyte metabolism and proliferation during heart regeneration.

The eIF4E family of translation initiation factors bind 5' methylated caps and act as the limiting step for mRNA translation. The canonical eIF4E1A is required for cell viability, yet other related eIF4E families exist and are utilized in specific contexts or tissues. Here, we describe a family called Eif4e1c, for which we find roles during heart development and regeneration in zebrafish.

Vitamin A deficiency compromises the barrier function of the retinal pigment epithelium.

A major cause for childhood blindness worldwide is attributed to nutritional vitamin A deficiency. Surprisingly, the molecular basis of the ensuing retinal degeneration has not been well defined. Abundant expression of the retinoid transporter STRA6 in the retinal pigment epithelium (RPE) and homeostatic blood levels of retinol-binding protein delay vitamin A deprivation of the mouse eyes.

Natamycin's inhibitory effects on were investigated using a drug-containing plate culture method and an in vivo assay in chestnuts and shell buckets. The antifungal mechanism of action of natamycin on was investigated by conducting staining experiments of the fungal cell wall and cell membrane.

β-Carotene regulates glucose transport and insulin resistance in gestational diabetes mellitus by increasing the expression of SHBG.

The aim of this work was to study the effect and mechanism of β-carotene on insulin resistance and glucose transport in gestational diabetes mellitus (GDM). Placental tissue and venous blood of 26 GDM patients and 18 normal women were collected. Mice fed a high-fat diet were established as GDM models and treated with β-carotene, from which peripheral blood and placenta tissue were collected.

Human placenta mesenchymal stem cell-derived exosome shuttling microRNA-130b-3p from gestational diabetes mellitus patients targets ICAM-1 and perturbs human umbilical vein endothelial cell angiogenesis.

Objective: The aim of this study was to investigate the roles of miR-130b-3p and ICAM-1 in gestational diabetes mellitus (GDM) and their potential association.

Methods: Human placenta mesenchymal stem cells (PlaMSCs) were isolated from GDM patients, and the effects of the PlaMSCs from GDM patients (GDM-MSCs) and the exosomes secreted by GDM-MSCs on human umbilical vein endothelial cell (HUVEC) proliferation, migration, and angiogenesis were detected. Next, GDM-MSCs were transfected with miR-130b-3p antagomir to modify miR-130b-3p expression in GDM-MSCs-derived exosomes, and the exosomes with modified miR-130b-3p expression were cultured with HUVECs to evaluate exosomal miR-130b-3p on HUVEC function.

Overexpression of hepatocyte growth factor protects chronic myeloid leukemia cells from apoptosis induced by etoposide.

Resistance to apoptosis induced by chemotherapy is still an obstacle for the treatment of chronic myeloid leukemia (CML). Numerous studies have indicated that upregulation of hepatocyte growth factor (HGF) protein expression reduced apoptosis induced by various factors. However, whether HGF has any effect on apoptosis induced by VP-16 (etoposide) in CML cells and its underlying mechanisms are unclear.

Colorado potato beetle exploits frass-associated bacteria to suppress defense responses in potato plants.

Background: Colorado potato beetle (CPB; Leptinotarsa decemlineata) is a destructive quarantine pest that develops broad physiological adaptations to potato plants. During feeding, CPB deposits a copious amount of wet frass onto the surface of leaves and stems that remains in place for long periods. Insect behaviors such as feeding, crawling and oviposition are able to mediate plant defenses.

Four flavonoid glycosides containing coumaroyl or feruloyl groups were isolated from the male flowers of L., and compounds and were identified as novel compounds. The inhibitory activities against α-glucosidase were investigated by docking studies, assays and kinetic studies.

Crystal structures and mechanical properties of osmium diboride at high pressure.

We have investigated the crystal structures and mechanical properties of osmium diboride (OsB) based on the density functional theory. The structures of OsB from 0 to 400 GPa were predicted using the particle swarm optimization algorithm structure prediction technique. The orthorhombic Pmmn structure of OsB (oP6-OsB) was found to be the most stable phase under zero pressure and it will transfer to the hexagonal P6/mmc structure (hP6-OsB) around 12.

CTLA-4 expression by B-1a B cells is essential for immune tolerance.

CTLA-4 is an important regulator of T-cell function. Here, we report that expression of this immune-regulator in mouse B-1a cells has a critical function in maintaining self-tolerance by regulating these early-developing B cells that express a repertoire enriched for auto-reactivity. Selective deletion of CTLA-4 from B cells results in mice that spontaneously develop autoantibodies, T follicular helper (Tfh) cells and germinal centers (GCs) in the spleen, and autoimmune pathology later in life.

Mitochondrial copper depletion suppresses triple-negative breast cancer in mice.

Depletion of mitochondrial copper, which shifts metabolism from respiration to glycolysis and reduces energy production, is known to be effective against cancer types that depend on oxidative phosphorylation. However, existing copper chelators are too toxic or ineffective for cancer treatment. Here we develop a safe, mitochondria-targeted, copper-depleting nanoparticle (CDN) and test it against triple-negative breast cancer (TNBC).

BHLHE40 plays a pathological role in pre-eclampsia through upregulating SNX16 by transcriptional inhibition of miR-196a-5p.

Pre-eclampsia (PE), which results from abnormal placentation, is a primary cause of maternal and neonatal morbidity and mortality. However, the causes of abnormal development of the placenta remain poorly understood. BHLHE40 is a transcriptional repressor in response to hypoxia.

Silicon-mediated multiple interactions: Simultaneous induction of rice defense and inhibition of larval performance and insecticide tolerance of by sodium silicate.

The rice striped stem borer (SSB, ) is one of the most destructive pests of rice plants. Si-mediated rice defense against various pests has been widely reported, and sodium silicate (SS) has been used as an effective source of silicon for application to plants. However, there is quite limited information about the direct effects of Si application on herbivorous insects.

Association between risk of preeclampsia and maternal plasma trimethylamine-N-oxide in second trimester and at the time of delivery.

Background: The data on the association between the microbiota-dependent metabolite trimethylamine-N-oxide (TMAO) during pregnancy and risk of preeclampsia (PE) is limited.
