Abstract
Rectal adenocarcinoma (READ) is a common malignant tumor of the digestive tract. Growing studies have confirmed Ras GTPase-activating proteins are involved in the progression of several tumors. This study aimed to explore the expression and function of Ras GTPase-activating proteins in READ. In this study, we analyzed RNA sequencing data from 165 patients with READ and 789 normal tissue samples, identifying 5603 differentially expressed genes (DEGs), including 2937 upregulated genes and 2666 downregulated genes. Moreover, we also identified two dysregulated genes, RASA4 and SYNGAP1, among six Ras GTPase-activating proteins. High NF1 expression was associated with longer overall survival, while high SYNGAP1 expression showed a trend towards extended overall survival. Further analysis revealed the mutation frequency and copy number variations of Ras GTPase-activating proteins in various cancer samples. Additionally, DNA methylation analysis demonstrated a negative correlation between DNA methylation of Ras GTPase-activating proteins and their expression. Moreover, among Ras GTPase-activating proteins, we focused on SYNGAP1, and experimental validation confirmed that the overexpression of SYNGAP1 in READ significantly suppressed READ cell proliferation and increased apoptosis via regulating the Wnt/β-Catenin signaling pathway. These findings underscored the potential significance of SYNGAP1 in READ and provide new insights for further research and treatment.

Abstract
BACKGROUND Acute myocardial infarction is one of the leading causes of death worldwide. Myocardial ischemia reperfusion (MI/R) injury occurs immediately after the coronary reperfusion and aggravates myocardial ischemia. Whether the Wnt/β-Catenin pathway is involved in the protection against MI/R injury by DADLE has not been evaluated. Therefore, the present study aimed to investigate the protective effect of DADLE against MI/R injury in a mouse model and to further explore the association between DADLE and the Wnt/β-Catenin pathway. METHODS Forty-four mice were randomly allocated to four groups: Group Control (PBS Control), Group D 0.25 (DADLE 0.25 mg/kg), Group D 0.5 (DADLE 0.5 mg/kg), and Group Sham. In the control and DADLE groups, myocardial ischemia injury was induced by occluding the left anterior descending coronary artery (LAD) for 45 min. PBS and DADLE were administrated, respectively, 5 min before reperfusion. The sham group did not go through LAD occlusion. 24 h after reperfusion, functions of the left ventricle were assessed through echocardiography. Myocardial injury was evaluated using TTC double-staining and HE staining. Levels of myocardial enzymes, including CK-MB and LDH, in the serum were determined using ELISA kits. Expression of caspase-3, TCF4, Wnt3a, and β-Catenin was evaluated using the Western blot assay. RESULTS The infarct area was significantly smaller in the DADLE groups than in the control group (P < 0.01). The histopathology score and serum levels of myocardial enzymes were significantly lower in the DADLE groups than in the control group (P < 0.01). DADLE significantly improved functions of the left ventricle (P < 0.01), decreased expression of caspase-3 (P < 0.01), TCF4 (P < 0.01), Wnt3a (P < 0.05), and β-Catenin (P < 0.01) compared with PBS. CONCLUSIONS The present study showed that DADLE protected the myocardium from MI/R through suppressing the expression of caspase-3, TCF4, Wnt3a, and β-Catenin and consequently improving functions of the left ventricle in I/R model mice. The TCF4/Wnt/β-Catenin signaling pathway might become a therapeutic target for MI/R treatment.

Abstract
Sanguinarine (C20H14NO4+), a plant alkaloid and pesticide, works well a fungicidal and insecticidal applications. The prospect that sanguinarine may have potentially toxic effects on aquatic organisms has been brought to light by its use in agriculture. The first evaluation of the immunotoxic and behavioral effects of sanguinarine exposure on larval zebrafish was done in this work. Firstly, zebrafish embryos exposed to sanguinarine had shorter body length, larger yolk sacs, and slower heart rates. Secondly, the number of innate immune cells was significantly reduced. Thirdly, alterations in locomotor behavior were observed as exposure concentrations increased. Total distance travelled, travel time, and mean speed were all reduced. We also found significant changes in oxidative stress-related indicators and a significant increase in apoptosis in the embryos. Further studies revealed aberrant expression of some key genes in the TLR immune signaling pathway including CXCL-c1c, IL8, MYD88, and TLR4. At the same time, the expression of the pro-inflammatory cytokine IFN-γ was upregulated. To sum up, our results suggest that sanguinarine exposure may cause immunotoxicity and aberrant behavior in larval zebrafish.

Abstract
As a neuronal transmembrane protein, leucine-rich repeat and fibronectin type-III domain-containing protein 2 (LRFN2) can recruit and combine with N-methyl-D-aspartic acid receptors (NMDARs) to promote nerve growth. Genetic studies suggest that mutations in LRFN2 are associated with various cancers. However, the role and mechanism of LRFN2 in the progression of esophageal squamous cell carcinoma (ESCC) have not been elucidated. In this study, we demonstrated that LRFN2 was significantly downregulated in ESCC tissues by qRT-PCR and immunohistochemistry. Low LRFN2 expression was an adverse prognostic factor in patients with ESCC. Overexpression of LRFN2 effectively suppressed the proliferation, migration, invasion and epithelial-to-mesenchymal transition in vitro and tumor growth in vivo. Bioinformatics analysis indicated that Wnt/β-catenin signaling regulation was one of the most potential mechanisms and studies confirmed that overexpression of LFRN2 obviously downregulated the expression of β-catenin, c-Myc and cyclin D1 in ESCC cells and tumor tissues. Further studies revealed that LRFN2 plays anti-ESCC role by binding with NMDAR-GRIN2B and this effect can be weakened by NR2B-selective NMDA antagonist-NMDA-IN-1. Moreover, the bioinformatics analysis showed that the interaction of GRIN2B and GSK3β affects the NF-κB pathway, which was demonstrated by western blot experiments. Collectively, our results indicate that LRFN2 binding to NMDARs inhibits the progression of ESCC by regulating the Wnt/β-catenin and NF-κB pathway, which provides a new therapeutic target for improving the prognosis of patients with ESCC.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Guizhi Fuling Capsule (GFC) is a famous traditional Chinese medicine (TCM) formula recorded in Synopsis of the Golden Chamber, which has achieved obvious effects in the treatment of uterine fibroids (UFs). AIM OF STUDY Mediator complex subunit 12 (Med12) mutations were closely related to UFs in 85% of fibroid cases. The Wnt/β-Catenin signaling pathway plays an important role in the occurrence and development of UFs. This study aims to explore the pharmacological mechanism of GFC against UFs in which the Med12-mediated Wnt/β-Catenin pathway is involved. MATERIALS AND METHODS Med12 was silenced in uterine fibroid cells (UFCs) using a lentivirus-based Med12 gene-specific RNA interference (RNAi) strategy. Cell proliferation was performed by CCK-8 assay, cell apoptosis and cell cycle were measured by flow cytometry. The rat model of UFs was established by injecting estradiol benzoate and progesterone. Forty-eight rats were divided into six groups, the low-dose GFC (L-GFC) group, the medium-dose GFC (M-GFC) group and the high-dose GFC (H-GFC) group were intragastrically treated with GFC solution at 0.25 g/kg, 0.50 g/kg and 1.00 g/kg per day for 8 weeks, the positive control (PC) group was administrated with mifepristone (2.70 mg/kg/day), the normal control (NC) group and the model control (MC) group were given equal volume of normal saline once a day for 8 weeks. The histopathological changes of uterine tissues were evaluated by H&E staining. The expression of Med12 in uterine tissues were detected by immunohistochemistry. The protein and mRNA levels of associated genes were evaluated by western bolt and real time-PCR, respectively. Related indicators involved in Wnt/β-Catenin pathway, such as Wnt1, β-Catenin, Cyclin D1, TCF1/TCF7 and C-myc, were compared among different groups. RESULTS The Wnt/β-Catenin signaling pathway was inhibited after Med12 gene was knocked out in UFCs. GFC-containing serum could induce cell apoptosis, make the cell cycle stagnated in G0/G1 phase to inhibiting the proliferation and reduce the expression of Wnt1, β-Catenin, Cyclin D1, TCF1/TCF7, and C-myc in control-shRNA cells, while had no significant effect on Med12-shRNA cells. Compared with the MC group, the weight, endometrial thickness, and pathological structure of the uterus in the GFC treated groups were significantly improved. The expression of Med12, Wnt1, β-Catenin, Cyclin D1, TCF1/TCF7, and C-myc that related to Wnt/β-Catenin pathway in the GFC treated groups were decreased with the increase of dosage administration. CONCLUSIONS GFC inhibited UFs growth, which was directly associated with Med12 modulated Wnt/β-Catenin signaling pathway. This study provided new perspective to understand the therapeutic mechanism of UFs.

Abstract
Daurisoline (DS) is one of the most abundant alkaloids extracted from the rhizome of Menispermum Dauricum DC, which is traditionally used to treat inflammatory diseases, especially intestinal inflammation. In this study, we established lipopolysaccharide (LPS)-induced RAW 264.7 macrophages in vitro and Dextran sulfate sodium (DSS)-induced colitis mice model in vivo to investigate the anti-inflammatory effect of DS and its underlying mechanisms. Disease activity index (DAI) was detected during drug intervention. The colon length, macroscopic changes and histopathological scores were adopted to observe the physiological status and the colon injury. The apoptosis of intestinal mucosa was detected using TUNEL. In addition, involved molecular indicators were measured by ELISA kits, RT-qPCR, immunofluorescence (IF), immunohistochemistry (IHC) and western blotting. The vitro experiments indicated that DS significantly suppressed the production of Nitric oxide (NO), reactive oxygen species (ROS) and glutathione (GSH), as well as inhibited the expression of NF-κB signaling pathway in RAW 264.7 cells induced by LPS. Consistent with the vitro experimental results, different doses of DS significantly reduced the incidence of diarrhea, DAI, shortening of the colon, visible damage and histological damage in DSS-induced colitis mice. Moreover, DS treatment decreased the levels of pro-inflammatory mediators cyclooxygenase-2 (COX-2), prostaglandin E2 (PGE2) and interleukin (IL)-1β, and increased the anti-inflammatory cytokines IL-4 and IL-10 in colon tissues. RT-qPCR, western blotting and immunofluorescence analyses further demonstrated that DS inhibits the expression of Wnt/β-Catenin pathway. We reported for the first time that DS may be an active ingredient in treating ulcerative colitis. Its mechanism might be related to the regulation of the NF-κB and Wnt/β-Catenin signaling pathway.

Abstract
Cerebral ischemic stroke is one of the leading causes of death and disability worldwide, and the only available drug treatment is limited to a short window following the ischemic event. Gastrodin is the major bioactive constituent extracted from thetuberGastrodia elata, and is currently used to treat dizziness in the clinic. "Early" application of gastrodin (before modeling or immediately after ischemic injury) has shown antioxidative and neuroprotective effects in a transient focal brain ischemia model in rodents; however, it is not known whether the delayed administration of gastrodin after permanent focal cerebral ischemia ameliorates neural injury and increases neurogenesis. In this study, we performed a permanent middle cerebral artery occlusion (MCAO) model for the study of cerebral ischemic stroke in adult male mice to examine the effects of gastrodin. Gastrodin treatment that was started "late" (one day after the ischemic injury) significantly improved neural function, reduced infarct volume and apoptosis, and increased the number of DCX/BrdU double-positive cells in permanent MCAO mice. Moreover, gastrodin treatment markedly preserved the Wnt/β-Catenin signaling pathway, which could promote neurogenesis and provide neuroprotection brain injury. Our findings suggest that gastrodin treatment following ischemic injury can induce neuroprotection, promote neurogenesis and restored the Wnt /β-Catenin signaling pathway.

Abstract
ETHNOPHARMACOLOGICAL SIGNIFICANCE Icariin (I), ferulic acid (F) and timosaponin B II (T) derived respectively from the leaf of Epimedium brevicornu Maxim (EBM, Berberidaceae), rhizome of Anemarrhena asphodeloides Bunge (AAB, Liliaceae) and root of Angelica sinensis (Oliv.) Diels (ASD, Umbelliferae) are included in several traditional Chinese medicine (TCM) formulas for the treatment of osteoporosis. In addition, the medicinal materials and chemical constituents in many traditional Chinese formulas have been shown to have potential synergistic, additive and antagonistic effects. AIM OF STUDY To explore the action mechanism and interactions between I, T and F as bone anabolic ingredients on osteoblasts, and fully understand their action mechanism and rationality of the formula design. MATERIALS AND METHODS An osteoporotic model was established in bilaterally ovariectomized mice. Bone mineral density (BMD), bone mineral content (BMC) and serum biochemical parameters including alkaline phosphatase (ALP), tartrate resistant acid phosphatase (TRAP), osteoprotegerin (OPG) and deoxypyridinoline cross-links (DPD) were measured to evaluate the effects of I, T or F alone and their combinations on osteoporotic mice. UMR-106 osteoblastic cells and primary osteoblasts in neonatal rat calvarias were used to evaluate the osteogenesis effect. The immunohistochemical method and Western-blot analysis were used to detect the expression of critical proteins in the process of proliferation and differentiation of osteoblasts. RESULTS IFT combinations enhanced the therapeutic effect without increasing the adverse effects on osteoporotic mice, synergistically increased the osteoblast proliferation, ALP activity and mineralized nodule formation, and promoted the expression of bone matrix by regulating BMP and Wnt/β-catenin signaling pathways in osteoblasts. CONCLUSION IFT combinations reinforced the therapeutic effect on osteoporosis by modulating multi-signaling pathways and action targets.
