Ferroptosis constitutes a critical pathological mechanism in cerebral ischemia-reperfusion injury (CI/RI), significantly influencing neurological outcomes. While dual specificity phosphatase 1 (DUSP1) demonstrates neuroprotective effects against CI/RI, its regulatory role in ferroptosis remains to be elucidated. This study systematically investigated the therapeutic potential of DUSP1 through ferroptosis modulation in both in vitro and in vivo models.

Introduction: Immunoglobulin A nephropathy (IgAN) and membranous nephropathy (MN) are among the most common forms of primary glomerular diseases, with a rising global incidence. Despite their clinical importance, the underlying pathogenesis of these diseases and the development of reliable non-invasive diagnostic tools remain inadequately understood. Accumulating evidence suggests that gut microbiota and its associated metabolites may play a crucial role in the development of kidney diseases via the gut-kidney axis.

Temporal lobe epilepsy (TLE) is the most common type of acquired epilepsy characterized by recurrent spontaneous seizures. The entorhinal cortex (EC) lies in the medial temporal lobe and serves as a relay center between the hippocampus and neocortex, and contains cholecystokinin-positive (CCK+) neurons. Increased CCK expression has been reported in patients with TLE suggesting its role in epilepsy development.

Chronic epilepsy is mainly characterized by spontaneous recurrent seizures (SRS). The peroxisome proliferator activated receptor gamma/phosphatase and tensin homolog/protein kinase B (PPARγ/PTEN/Akt) pathway is involved in the pathogenesis of SRS and neuronal loss. Curcumin is a natural compound, and previous studies have shown it provides neuroprotection via anti-inflammation and anti-oxidant effects in many central nervous system (CNS) diseases.

Cells possess numerous metabolite sensors that detect essential nutrients for growth, with many directly binding to metabolites and responding to their levels. Given the vital role of arginine in various physiological and pathological processes, we hypothesized that there may be undiscovered sensors that detect arginine deficiency. Through a series of unbiased screening strategies in human cancer cell line models, we identified Bcl2-associated athanogene (BAG) family molecular chaperone regulator 2 (BAG2) as an arginine sensor, which could directly bind to arginine at the glutamine residue 167 (Q167).

The widespread distribution of environmental contaminants poses a significant threat to public health. N-(1,3-dimethylbutyl)-N'-phenyl-p-phenylenediamine (6PPD) and its ozone-derivative, 6PPD-quinone (6PPD-Q), are emerging pollutants that propagate through particulate matter and aerosols, exerting detrimental effects on the respiratory system. However, their specific pathogenic mechanisms remain unclear.

To investigate the key regulatory genes and pathways related to growth traits in the Dongtingking crucian carp (Carassius auratus indigentiaus), the transcriptomes of brain, intestine, and muscle tissues were sequenced at early juvenile stage using RNA-Seq from two groups with extreme growth rates (fast-growing and slow-growing). A total of 65, 184, and 130 differentially expressed genes (DEGs) were detected in the brain, intestine, and muscle, respectively. Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway analysis highlighted that the PPAR signaling pathway, Insulin/PI3K/Akt/mTOR/FoxO/AMPK pathway, and Protein digestion and absorption pathways are crucial for growth in this species.

Inflammatory cytokines play a crucial role in Creutzfeldt-jakob disease (CJD). We examined inflammatory cytokine levels in both blood and CSF in a CJD patient and an epileptic encephalopathy as a control case. Results showed that IL-6, IL-8, IL-1β, and TNF-α levels were elevated in blood, but only IL-8 and IL-1β levels, especially IL-8, were significantly elevated in Cerebrospinal fluid (CSF).

Long non-coding RNAs (lncRNAs) have been recognized for their crucial roles in the replication processes of various viruses. However, the specific functions and regulatory mechanisms of many lncRNAs in influenza A virus (IAV) pathogenesis remain poorly understood. In this study, we identified lncRNA THRIL and observed a significant reduction in its expression following IAV infection in A549 cells.

Shunt dependence syndrome is a serious long-term complication characterized by symptoms and signs of increased intracranial pressure with normal-sized lateral ventricles after several years of arachnoid cyst-peritoneal shunting. It is easy to misdiagnose and overlook when combined with sinus stenosis, thus delaying treatment. Here, we present a 35-year-old man with an unexplained headache and binocular horizontal diplopia with high intracranial pressure.

High-frequency stimulation (HFS)-induced long-term potentiation (LTP) is generally regarded as a homosynaptic Hebbian-type LTP, where synaptic changes are thought to occur at the synapses that project from the stimulation site and terminate onto the neurons at the recording site. In this study, we first investigated HFS-induced LTP on urethane-anesthetized rats and found that cortical HFS enhances neural responses at the recording site through the strengthening of local connectivity with nearby neurons at the stimulation site rather than through synaptic strengthening at the recording site. This enhanced local connectivity at the stimulation site leads to increased output propagation, resulting in signal potentiation at the recording site.

Allergic diseases affect more than a quarter of individuals in industrialized countries, and are a major public health concern. The high-affinity Fc receptor for immunoglobulin E (FcεRI), which is mainly present on mast cells and basophils, has a crucial role in allergic diseases. Monomeric immunoglobulin E (IgE) binding to FcεRI regulates mast cell survival, differentiation and maturation.

Article Synopsis
  • Previous studies suggest that gut microbiota (GM) might influence epilepsy through the microbiota-gut-brain axis, but the exact relationship and the role of inflammatory proteins in this process remain unclear.
  • The researchers used genome-wide association study data to identify genetic variants linked to GM, inflammatory proteins, and different epilepsy types, applying a statistical method called Multivariate Mendelian Randomization to explore these connections.
  • The findings revealed numerous causal associations between GM, inflammatory proteins, and epilepsy, highlighting CXCL11 as a potential mediator in how GM influences epileptogenesis.

Article Synopsis
  • Grain-filling in rice spikelets is crucial for yield and quality, and this study focuses on how ratooning (growing a second crop from stubble) affects this process in two rice varieties: 'Jinhui 809' and 'Yongyou 1540'.
  • The results show that the inferior spikelets in ratoon season rice (ISR) benefit from improved grain-filling, reflected in earlier filling, higher seed-setting, and better quality compared to main crop rice (ISL).
  • Proteomic analysis revealed significant protein changes linked to improved grain-filling, highlighting the role of metabolic processes and the key protein GF14f, which declined faster in ISR and correlated with enhanced starch synthesis and hormone levels.
