A Nonaugmented Method for the Minimal Observability of Boolean Networks.

This article proposes a nonaugmented method for investigating the minimal observability problem of Boolean networks (BNs). This method can be applied to more general BNs and reduce the computational and space complexity of existing results. First, unobservable states concerning an unobservable BN are classified into three categories using the vertex-colored state transition graph, each accompanied by a necessary and sufficient condition for determining additional measurements to make them distinguishable.

Inhibition of the AP-1/TFPI2 axis contributes to alleviating cerebral ischemia/reperfusion injury by improving blood-brain barrier integrity.

Reperfusion after cerebral ischemia leads to secondary damage to the nervous system, called cerebral ischemia/reperfusion injury (CIRI). The blood-brain barrier (BBB) consists of endothelial cells and tight junction (TJ) proteins, and its disruption aggravates CIRI. Two GSE datasets identified Tissue Factor Pathway Inhibitor 2 (TFPI2) as a differentially upregulated gene (Log2FC > 1, p < 0.

SEH1L siliencing induces ferroptosis and suppresses hepatocellular carcinoma progression via ATF3/HMOX1/GPX4 axis.

SEH1 like nucleoporin (SEH1L) is an important component of nuclear pore complex (NPC), which is crucial in the regulation of cell division. However, the interrelation between SEH1L expression and tumor progression is less studied. In this research, we performed a systematic bioinformatic analysis about SEH1L using TCGA, Timer 2.

Targeted inhibition of STAT3 (Tyr705) by xanthatin alleviates osteoarthritis progression through the NF-κB signaling pathway.

The transcription factor, signal transducer, and stimulator of transcription 3 (STAT3) is a potential target in osteoarthritis (OA) treatment. Although xanthatin (XA), a biologically active substance derived from Xanthium strumarium L, specifically inhibits STAT3 phosphorylation at Tyr705, the mechanism underlying its inhibitory effect on OA progression remains unclear. In this study, our objective was to explore the therapeutic effects exerted by XA on OA and the underlying molecular mechanisms.

Activating transcriptional coactivator with PDZ-binding motif by (R)-PFI-2 attenuates osteoclastogenesis and prevents ovariectomized-induced osteoporosis.

Excessive osteoclast activation is a leading cause of osteoporosis. Therefore, identifying molecular targets and relevant pharmaceuticals that inhibit osteoclastogenesis is of substantial clinical importance. Prior research has indicated that transcriptional coactivator with PDZ-binding motif (TAZ) impedes the process of osteoclastogenesis by engaging the nuclear factor (NF)-κB signaling pathway, thereby suggesting TAZ activation as a potential therapeutic approach to treat osteoporosis.

Biodegradable cellulose/curcumin films with Janus structure for food packaging and freshness monitoring.

The development of renewable, hydrophobic, and biodegradable intelligent packaging materials as an alternative to petroleum-based plastic products has become a new research focus in recent years, but remains a challenge. Herein, regenerated cellulose/curcumin composite films were fabricated by dispersing hydrophobic curcumin uniformly in a hydrophilic cellulose matrix using an aqueous alkali/urea solvent based on the pH-driven principle of curcumin. In addition, a unilateral hydrophobic modification was carried out using chemical vapor deposition of methyltrichlorosilane to obtain Janus structure.

Acetylation of MOB1 mediates polyphyllin II-reduced lysosome biogenesis in breast cancer by promoting the cytoplasmic retention of the YAP/TFEB coactivator complex.

Background: Autophagy‒lysosome abnormalities are associated with the malignant progression of cancer. Transcription factor EB (TFEB) is the master transcriptional regulator of the autophagy‒lysosome machinery, and its abnormal activity is associated with autophagy-lysosome dysfunction. Polyphyllin II (PPII), an active steroidal saponin isolated from the rhizomes of Paris polyphylla, has been demonstrated to have antitumor activity.

Integrated Multi-Tissue Transcriptome Profiling Characterizes the Genetic Basis and Biomarkers Affecting Reproduction in Sheep ().

The heritability of litter size in sheep is low and controlled by multiple genes, but the research on its related genes is not sufficient. Here, to explore the expression pattern of multi-tissue genes in Chinese native sheep, we selected 10 tissues of the three adult ewes with the highest estimated breeding value in the early study of the prolific Xinggao sheep population. The global gene expression analysis showed that the ovary, uterus, and hypothalamus expressed the most genes.

T-lymphokine-activated killer cell-originated protein kinase (TOPK) is a serine-threonine kinase that is overexpressed in gastric cancer (GC) and promotes tumor progression. Polyphyllin VII (PPVII), a pennogenin isolated from the rhizomes of Paris polyphylla, shows anticancer effects. Here, we explored the antitumor activity and mechanism of PPVII in GC.

Chinese expert consensus on the diagnosis and treatment of malignant pleural mesothelioma.

Malignant pleural mesothelioma (MPM) is a malignant tumor originating from the pleura, and its incidence has been increasing in recent years. Due to the insidious onset and strong local invasiveness of MPM, most patients are diagnosed in the late stage and early screening and treatment for high-risk populations are crucial. The treatment of MPM mainly includes surgery, chemotherapy, and radiotherapy.

Separation of transcriptional repressor and activator functions in Drosophila HDAC3.

The histone deacetylase HDAC3 is associated with the NCoR/SMRT co-repressor complex, and its canonical function is in transcriptional repression, but it can also activate transcription. Here, we show that the repressor and activator functions of HDAC3 can be genetically separated in Drosophila. A lysine substitution in the N terminus (K26A) disrupts its catalytic activity and activator function, whereas a combination of substitutions (HEBI) abrogating the interaction with SMRTER enhances repressor activity beyond wild type in the early embryo.
