This study investigated the efficacy, underlying mechanism, and responsible active compounds of the traditional Chinese medicinal prescription Chaihuang Qingyi Huoxue granule (CHQY) in treating SAP-induced intestinal mucosal barrier injury. SAP was established in Sprague-Dawley rats via intra-pancreaticobiliary duct infusion of sodium taurocholate, followed by oral CHQY administration (3.

Hua Polysaccharide Alleviates Fatigue by Modulating Osteocalcin-Mediated Crosstalk between Bones and Muscles.

Osteocalcin was reported to regulate muscle energy metabolism, thus fighting fatigue during exercise. The current work aimed to investigate the anti-fatigue effect and the underlying mechanism of a homogeneous polysaccharide (PCPY-1) from after structure characterization. In the exhaustive swimming mouse model and the co-culture system of BMSCs/C2C12 cells, PCPY-1 significantly stimulated BMSC differentiation into osteoblasts as determined by ALP activity, matrix mineralization, and the protein expressions of osteogenic markers BMP-2, phosphor-Smad1, RUNX2, and osteocalcin.

Bioactive polysaccharides and their potential health benefits in reducing the risks of atherosclerosis: A review.

Atherosclerosis is a kind of lipid-driven chronic inflammatory disease of arteries and is the principal pathological basis of life-threatening cardiovascular disease events, such as strokes and heart attacks. Clinically, statins are the most commonly prescribed drugs for the treatment of atherosclerosis, but prolonged use of these drugs exhibit many adverse reactions and have limited efficacy. Polysaccharides are important natural biomacromolecules widely existing in plants, animals, microorganisms and algae.

LINC01554-Mediated Glucose Metabolism Reprogramming Suppresses Tumorigenicity in Hepatocellular Carcinoma via Downregulating PKM2 Expression and Inhibiting Akt/mTOR Signaling Pathway.

Cancer cells prefer aerobic glycolysis to maintain growth advantages, but the role of long non-coding RNAs (lncRNAs) in glycometabolism still remains unclear. Here we identified one cytoplasmic lncRNA LINC01554 as a significantly downregulated lncRNA in hepatocellular carcinoma (HCC) and aimed to investigate its role in cellular glucose metabolism in the development and progression of HCC. Quantitative real-time PCR was used to determine the expression level of LINC01554.

Expansion of cancer stem cell pool initiates lung cancer recurrence before angiogenesis.

Angiogenesis is essential in the early stage of solid tumor recurrence, but how a suspensive tumor is reactivated before angiogenesis is mostly unknown. Herein, we stumble across an interesting phenomenon that s.c.

Dipalmitoylphosphatidic acid inhibits tumor growth in triple-negative breast cancer.

Triple-negative breast cancer (TNBC) is a subtype of breast cancer with a poor prognosis, accounting for approximately 12-24% of breast cancer cases. Accumulating evidence has indicated that there is no effective targeted therapy available for TNBC. Dipalmitoylphosphatidic acid (DPPA) is a bioactive phospholipid.

Transgenic over-expression of slit2 enhances disruption of blood-brain barrier and increases cell death after traumatic brain injury in mice.

Traumatic brain injury (TBI) is the leading cause of mortality and disability among male adolescents and young adults; and mild traumatic brain injury is the most common type of traumatic brain injury. The disruption of blood-brain barrier (BBB) plays an important role in brain trauma. Previously, we have found that slit2, a member of slit protein family, increases permeability of BBB.

High salt intake negatively impacts ovarian follicle development.

Many human disorders induce high salinity in tissues and organs, interfering with their normal physiological functions. Using a mouse model, we demonstrated that high salt intake caused infertility. Specifically, we established that high salinity dramatically affects ovarian follicle development and the extent of follicular atresia.

Autophagy is involved in high glucose-induced heart tube malformation.

Both pre-gestational and gestational diabetes have an adverse impact on heart development, but little is known about the influence on the early stage of heart tube formation. Using early gastrulating chick embryos, we investigated the influence of high glucose on the process of heart tube formation, specifically during the primary heart field phase. We demonstrated that high-glucose exposure resulted in 3 types of heart tube malformation: 1) ventricular hypertrophy, 2) ventricular hypertrophy with dextrocardia and 3) ventricular hypertrophy and dextrocardia with the fusion anomaly of a bilateral primary heart tube.

Slit2/Robo1 signaling promotes intestinal tumorigenesis through Src-mediated activation of the Wnt/β-catenin pathway.

Slit2 is often overexpressed in cancers. Slit2 is a secreted protein that binds to Roundabout (Robo) receptors to regulate cell growth and migration. Here, we employed several complementary mouse models of intestinal cancers, including the Slit2 transgenic mice, the ApcMin/+ spontaneous intestinal adenoma mouse model, and the DMH/DSS-induced colorectal carcinoma model to clarify function of Slit2/Robo1 signaling in intestinal tumorigenesis.

Andrographolide inhibits melanoma tumor growth by inactivating the TLR4/NF-κB signaling pathway.

The TLR4/NF-κB signaling pathway plays a critical role in tumor progression. Andrographolide (Andro) has been reported to have anticancer activity in multiple types of cancer. However, the pharmacological activities of Andro in melanoma are not completely understood.

Increased permeability of the blood-brain barrier and Alzheimer's disease-like alterations in slit-2 transgenic mice.

Alzheimer's disease (AD) is a progressive neurological disorder that primarily affects memory, and its prevalence is rising. Increasing evidence suggests that dysfunction of the blood-brain barrier (BBB) may be involved in AD and other neurodegenerative diseases. Herein, we report that the permeability of the BBB is increased and that AD-like alterations are present in Slit-2 overexpressing transgenic mice.

Podoplanin‑positive cancer cells at the edge of esophageal squamous cell carcinomas are involved in invasion.

Podoplanin (PDPN) is a well established lymphatic endothelial marker and has frequently been observed in cancer cells at the edge of cancer masses. Previous studies investigating the association between PDPN expression and patient prognosis have had contradictory results. In the present study, it was hypothesized that the different locations of PDPN‑positive cells may explain these varying results.

Andrographolide suppress tumor growth by inhibiting TLR4/NF-κB signaling activation in insulinoma.

Insulinomas are rare tumors, and approximately 10% of insulinomas are malignant. Accumulating evidence has implicated that we still lack effective therapy to treat the patients who are diagnosed with rare malignant insulinoma. Previous studies have reported that Andrographolide (Andro) could inhibit cell cycle progression, reduce cell invasion and induce cell apoptosis in many common cancer cells.

P-selectin-mediated platelet adhesion promotes the metastasis of murine melanoma cells.

Studies have indicated that the aggregation of activated platelets with cancer cells facilitates tumor metastasis; the adhesion molecule P-selectin may be an important mediator of this process, but the detailed mechanism is unclear. In the current study, we established a B16F10 (B16) cell metastatic model in P-selectin knockout (P-sel-/-) mice to determine the effect of P-selectin-mediated platelet adhesion on metastasis. Compared with C57 mice, P-sel-/- mice developed fewer metastatic foci, and cell proliferation within the metastatic tumors was inhibited by P-selectin deficiency.

Micrometastasis expressing insulin arise in lung and spleen at advanced stage of rip1-tag2 transgenic mice.

Rip1-Tag2 mice is one overt pancreatic β-cell tumor model, which is widely used for studying pancreas tumor angiogenesis and tumor development. However, tumor metastasis in Rip1-Tag2 mice had rarely been reported, in this present study, we find some micrometastasis in lung and spleen of the Rip1-Tag2 mice at advanced stage, which is important for uncovering metastasis cell characteristics and exploring how to survive in cancer microenvironment. To study the micrometastasis of Rip1-Tag2 mice in advanced pancreatic cancer, we first observed the pathology process of β cell tumor in Rip1-Tag2 mice through HE staining, then we performed immunohistochemistry with insulin antibody, T-antigen antibodies and C-petide antibody on lung and spleen tissues sections from advanced stage, comparing with background wild-type C57BL/6 mice sections.

A novel four-step system for screening angiogenesis inhibitors.

Angiogenesis exhibits a significant effect on tumor progression. Inhibiting angiogenesis may provide significant advantages over currently available therapeutics for cancer therapies thus, the development of a system of screening angiogenesis is essential. In the present study, a novel available system of screening angiogenesis inhibitors by four steps was developed.

Investigation of tumor suppressing function of CACNA2D3 in esophageal squamous cell carcinoma.

Background: Deletion of 3p is one of the most frequent genetic alterations in esophageal squamous cell carcinoma (ESCC), suggesting the existence of one or more tumor suppressor genes (TSGs) within these regions. In this study, one TSG, CACNA2D3 at 3p21.1, was characterized.
