Matrine protects against DSS-induced murine colitis by improving gut barrier integrity, inhibiting the PPAR-α signaling pathway, and modulating gut microbiota.

Matrine is a naturally occurring quinolizidine alkaloid with various bioactivities. However, little is known of its function on ulcerative colitis (UC). Here, we investigated the effect and underlying mechanisms of matrine on dextran sulfate sodium (DSS)-induced UC mice.

Role of PRPS2 as a prognostic and therapeutic target in osteosarcoma.

Aims: Osteosarcoma (OS) is the most common primary malignant tumour of the bone. However, further improvement in survival has not been achieved due to a lack of well-validated prognostic markers and more effective therapeutic agents. Recently, the c-Myc-phosphoribosyl pyrophosphate synthetase 2 (PRPS2) pathway has been shown to promote nucleic acid metabolism and cancer cell proliferation in malignant melanoma; phosphorylated mammalian target of rapamycin (p-mTOR) has been upregulated and an effective therapeutic target in OS.

CDKL3 promotes osteosarcoma progression by activating Akt/PKB.

Osteosarcoma (OS) is a primary malignant bone neoplasm with high frequencies of tumor metastasis and recurrence. Although the Akt/PKB signaling pathway is known to play key roles in tumorigenesis, the roles of cyclin-dependent kinase-like 3 (CDKL3) in OS progression remain largely elusive. We have demonstrated the high expression levels of CDKL3 in OS human specimens and comprehensively investigated the role of CDKL3 in promoting OS progression both in vitro and in vivo.

Network pharmacology-based identification of the protective mechanisms of taraxasterol in experimental colitis.

Background And Aim: Taraxasterol, a pentacyclic-triterpene, has been reported to exert potent anti-inflammatory activity. However, the molecular mechanisms by which taraxasterol attenuates acute experimental colitis (AEC) remain undocumented.

Methods: A network pharmacology approach was used to identify the candidate and collective targets of taraxasterol and acute colitis, and an AEC model was established by oral administration of dextran sulfate sodium (DSS) in mice.

Minichromosome maintenance protein 2 and 3 promote osteosarcoma progression via DHX9 and predict poor patient prognosis.

A label free quantitative proteomic approach (SWATH™ experiment) was performed to identify tumor-associated nuclear proteins that are differentially expressed between osteosarcoma cells and osteoblast cells. By functional screening, minichromosome maintenance protein 2 (MCM2) and minichromosome maintenance protein 3 (MCM3) were found to be related to osteosarcoma cell growth. Here, we show that knockdown of MCM2 or MCM3 inhibits osteosarcoma growth in vitro and in vivo.

Mixed epithelial and stromal tumor of the kidney: report of a rare case and review of literature.

Mixed epithelial and stromal tumor of the kidney (MESTK) is a rare benign tumor composed of epithelial and stromal cells. We report a rare male case with detailed clinicopathological data and follow-up information. The patient presented with gross hematuria.

Insights into Trx1, TRP14, and Prx1 homologs of Paralichthys olivaceus: molecular profiles and transcriptional responses to immune stimulations.

Thioredoxin (Trx) proteins are involved in several cellular processes, such as anti-oxidative stress and cellular redox homeostasis. In this study, we isolated the full-length cDNAs of PoTrx1 and PoTRP14 from Japanese flounder (Paralichthys olivaceus). PoTrx1 is 723 bp in length, with a 366-bp open reading frame (ORF) that encodes for 121 amino acids.

[Accuracy of different preoperative biopsy techniques in diagnosis of osteosarcomas and their value in prognostic evaluation].

Objective: To study the difference in pathologic diagnostic accuracy among different histologic subtypes of osteosarcoma and different methods of preoperative biopsy, and the influence of diagnostic accuracy on prognosis of osteosarcoma.

Methods: The preoperative biopsies, complete clinical, radiological and pathological data of 347 pathologically confirmed osteosarcomas were evaluated. According to the Pathological Diagnostic and Technical Specifications, the accuracy of preoperative biopsies was divided into 6 grades.
