Abstract
Backgrounds As a systemic skeletal dysfunction, osteoporosis (OP) is characterized by low bone mass and bone microarchitectural damage. The global incidences of OP are high. Methods Data were retrieved from databases like Gene Expression Omnibus (GEO), GeneCards, Search Tool for the Retrieval of Interacting Genes/Proteins (STRING), Gene Expression Profiling Interactive Analysis (GEPIA2), and other databases. R software (version 4.1.1) was used to identify differentially expressed genes (DEGs) and perform functional analysis. The Least Absolute Shrinkage and Selection Operator (LASSO) logistic regression and random forest algorithm were combined and used for screening diagnostic markers for OP. The diagnostic value was assessed by the receiver operating characteristic (ROC) curve. Molecular signature subtypes were identified using a consensus clustering approach, and prognostic analysis was performed. The level of immune cell infiltration was assessed by the Cell-type Identification by Estimating Relative Subsets of RNA Transcripts (CIBERSORT) algorithm. The hub gene was identified using the CytoHubba algorithm. Real-time fluorescence quantitative PCR (RT-qPCR) was performed on the plasma of osteoporosis patients and control samples. The interaction network was constructed between the hub genes and miRNAs, transcription factors, RNA binding proteins, and drugs. Results A total of 40 DEGs, eight OP-related differential genes, six OP diagnostic marker genes, four OP key diagnostic marker genes, and ten hub genes (TNF, RARRES2, FLNA, STXBP2, EGR2, MAP4K2, NFKBIA, JUNB, SPI1, CTSD) were identified. RT-qPCR results revealed a total of eight genes had significant differential expression between osteoporosis patients and control samples. Enrichment analysis showed these genes were mainly related to MAPK signaling pathways, TNF signaling pathway, apoptosis, and Salmonella infection. RT-qPCR also revealed that the MAPK signaling pathway (p38, TRAF6) and NF-kappa B signaling pathway (c-FLIP, MIP1β) were significantly different between osteoporosis patients and control samples. The analysis of immune cell infiltration revealed that monocytes, activated CD4 memory T cells, and memory and naïve B cells may be related to the occurrence and development of OP. Conclusions We identified six novel OP diagnostic marker genes and ten OP-hub genes. These genes can be used to improve the prognostic of OP and to identify potential relationships between the immune microenvironment and OP. Our research will provide insights into the potential therapeutic targets and pathogenesis of osteoporosis.

Abstract
Mounting evidence shows that organophosphate flame retardants (OPFRs), especially aryl- and halogenated-OPFRs, exert various adverse health effects on living organisms. This study evaluated the hepatotoxic effect of trihexyl phosphate (THP) as a long-chain alkyl-OPFR on human hepatocyte cells (LO2) and mouse hepatocyte cells (AML12) by performing screening of cytotoxicity in vitro. In combination with transcriptomic analysis, toxicological mechanisms in vitro were further investigated. Results showed that THP triggered hepatotoxicity in vitro by altering four signaling pathways: endoplasmic reticulum (ER) stress, apoptosis, cell cycle, and the glycolysis signaling pathway. Exposure of LO2 and AML12 liver cells to THP (25 μg/mL) significantly induced ER stress-mediated apoptosis and cell cycle arrest. Meanwhile, downregulation of glycolysis caused the blockage of energy metabolism. Furthermore, the high performance liquid chromatography-quadrupole time-of-flight mass spectrometry (HPLC-Q-TOF-MS/MS) revealed that much of THP was absorbed into the cells and displayed stability in the two liver cell lines. In vivo assays using a mouse model demonstrated that exposure to THP at 400 mg/kg induced the ballooning degeneration of hepatocytes in liver tissue, whereas exposure to THP at 800 mg/kg caused acute liver injury with high alanine aminotransferase levels. This study provides novel insights into the impact of THP on hepatotoxicity in vitro and in vivo and uncovers the underlying toxicological mechanisms, which may serve as a guide for further ecological risk assessment and reasonable application of alkyl-OPFRs.

Abstract
Recent studies have shown that spindle and kinetochore-associated protein 2 (SKA2) is dysregulated in multiple tumors and acts as a key regulator of tumor progression. However, whether SKA2 plays a role in hepatocellular carcinoma (HCC) has not been fully elucidated. The purpose of this study was to explore the expression, function and underlying molecular mechanism of SKA2 in HCC. We found that SKA2 was highly expressed in HCC tissues and cell lines. Knockdown of SKA2 caused marked reductions in the proliferative, colony-forming and invasive capacities of HCC cells, while SKA2 overexpression had opposite effects. Further experiments revealed that overexpression of SKA2 enhanced expression levels of phosphorylated glycogen synthase kinase-3β (GSK-3β) and active β-catenin in HCC cells. Moreover, SKA3 overexpression enhanced transcriptional activity mediated by Wnt/β-catenin signaling. Knockdown of SKA3 downregulated the activation of Wnt/β-catenin signaling, and the effect was significantly reversed by the inhibition of GSK-3β. Notably, inhibition of Wnt/β-catenin signaling markedly abrogated SKA2-mediated promotion effect on HCC proliferation and invasion. In addition, knockdown of SKA2 impeded tumor formation and growth in HCC cells in a nude mouse in vivo model. Overall, these findings indicate that SKA2 accelerates the progression of HCC through the upregulation of Wnt/β-catenin signaling. Our study highlights a potential role of SKA2 in HCC progression and suggests it as a possible target for HCC treatment.

Abstract
MicroRNAs (miR) serve important roles in the development and progression of tumors by targeting different genes. miR-520a-3p reported in lung and breast cancers as a tumor suppressor gene. However, the expression and functional significance of miR-520a-3p is not completely understood in gastric cancer (GC). In the present study, it was demonstrated that the expression levels of miR-520a-3p were significantly downregulated in GC tissues and cells using RT-qPCR. In addition, downregulated expression of miR-520a-3p was associated with the clinical stage of the tumor and invasion in patients with GC. Furthermore, overexpression of miR-520a-3p significantly inhibited cell proliferation, invasion and migration in SGC-7901 and MGC-803 GC cell lines using proliferation, wound healing and cell invasion assays. Spindle and kinetochore associated 2 (SKA2) was upregulated in GC cells using western blot analysis and a target gene of miR-520a-3p; miR-520a-3p mimics significantly reduced SKA2 expression. In addition, upregulation of SKA2 protein expression SKA2 reversed the miR-520a-3p-mediated inhibition of SGC-7901 cell proliferation, migration and invasion. In conclusion, miR-520a-3p functioned as a tumor suppressor gene by targeting SKA2 in GC cell lines, and may serve as a novel prognostic and potential therapeutic marker.

Abstract
Spindle and kinetochore‑associated protein 2 (SKA2) is essential for regulating the progression of mitosis. In recent years, SKA2 upregulation has been detected in various human malignancies and the role of SKA2 in tumorigenesis has received increasing attention. However, the expression and functional significance of SKA2 in breast cancer are not completely understood. To study the effects of SKA2 on breast cancer, the expression levels of SKA2 in breast cancer tissues and cell lines were evaluated by western blotting, reverse transcription‑quantitative polymerase chain reaction and immunohistochemical staining. The results demonstrated that SKA2 expression was increased in breast cancer tissues and cells, and SKA2 overexpression was associated with clinical stage and lymph node metastasis. Functional investigations revealed that SKA2 knockdown in breast cancer cells significantly reduced migration and invasion, and resulted in the decreased expression levels of matrix metalloproteinase (MMP)2 and MMP9. Furthermore, the typical microtubule arrangement was altered in SKA2 small interfering RNA (siSKA2)‑transfected cells. Reduced levels of SKA2 also downregulated the expression of epithelial‑mesenchymal transition proteins, including fibronectin, N‑cadherin and vimentin, whereas there were no alterations in the protein expression levels of E‑cadherin. Conversely, upregulation of SKA2 decreased the expression levels of E‑cadherin, and increased N‑cadherin, fibronectin and vimentin levels. Notably, it was demonstrated that E‑cadherin was translocated from the cytoplasm to the nucleus in siSKA2‑transfected cells. These results demonstrated that SKA2 may be associated with breast cancer metastasis, and siSKA2 inhibited the invasion and metastasis of breast cancer via translocation of E‑cadherin from the cytoplasm to the nucleus.

Abstract
A cytotoxicity-guided phytochemical investigation of Anemone vitifolia roots led to the isolation of six oleanane saponins (1-6), which were reported from the species for the first time. Their structures were determined by comparing its MS and NMR data with those in literature. Compounds 1-4 showed significant inhibitory effects on the proliferation of hepatocellular carcinoma HepG2 cells with IC50 values ranging from 2.0 to 8.5 μM, compared to positive control methotrexate with IC50 value of 15.8 μM. Flow cytometry analysis revealed that compounds 1-4 exerted anti-proliferative effects through a pro-apoptotic way of hepatocellular carcinoma cells.

Abstract
The Ranunculaceae genus Anemone (order Ranunculales), comprising more than 150 species, mostly herbs, has long been used in folk medicine and worldwide ethnomedicine. Various medicinal compounds have been found in Anemone plants, especially triterpenoid saponins, some of which have shown anti-cancer activities. Some Anemone compounds and extracts display immunomodulatory, anti-inflammatory, antioxidant, and antimicrobial activities. More than 50 species have ethnopharmacological uses, which provide clues for modern drug discovery. Anemone compounds exert anticancer and other bioactivities via multiple pathways. However, a comprehensive review of the Anemone medicinal resources is lacking. We here summarize the ethnomedical knowledge and recent progress on the chemical and pharmacological diversity of Anemone medicinal plants, as well as the emerging molecular mechanisms and functions of these medicinal compounds. The phylogenetic relationships of Anemone species were reconstructed based on nuclear ITS and chloroplast markers. The molecular phylogeny is largely congruent with the morphology-based classification. Commonly used medicinal herbs are distributed in each subgenus and section, and chemical and biological studies of more unexplored taxa are warranted. Gene expression profiling and relevant "omics" platforms could reveal differential effects of phytometabolites. Genomics, transcriptomics, proteomics, and metabolomics should be highlighted in deciphering novel therapeutic mechanisms and utilities of Anemone phytometabolites.
