Dual luciferase reporter assays confirmed that miR-129-5p binds directly to the 3'-UTR of ZRANB2 mRNA. Furthermore, miR-129-5p overexpression or ZRANB2 knockdown reduces proliferation and colony formation of FAM181A-AS1 overexpressing glioma cells. These findings show that FAM181A-AS1 promotes gliomagenesis by enhancing ZRANB2 expression by sponging of miR-129-5p.Breast cancer patients at the same stage may show different clinical prognoses or different therapeutic effects of systemic therapy. Differentially expressed genes of breast cancer were identified from GSE42568. Through survival, receiver operating characteristic (ROC) curve, random forest, GSVA and a Cox regression model analyses, genes were identified that could be associated with survival time in breast cancer. The molecular mechanism was identified by enrichment, GSEA, methylation and SNV analyses. Then, the expression of a key gene was verified by the TCGA dataset and RT-qPCR, Western blot, and immunohistochemistry. read more We identified 784 genes related to the 5-year overall survival time of breast cancer. Through ROC curve and random forest analysis, 10 prognostic genes were screened. These were integrated into a complex by GSVA, and high expression of the complex significantly promoted the recurrence-free survival of patients. In addition, key genes were related to immune and metabolic-related functions. Importantly, we identified methylation of MEX3A and TBC1D 9 and mutations events. Finally, the expression of UGCG was verified by the TCGA dataset and by experimental methods in our own samples. These results indicate that 10 genes may be potential biomarkers and therapeutic targets for long-term survival in breast cancer, especially UGCG.The aim of this study was to evaluate the fertilizing capacity of frozen or vitrified stallion sperm after assessing different warming procedures. In Experiment 1, different warming procedures were compared after sperm vitrification immersion in extender at 43 °C (C), or in a water bath at 37 °C/30 s (W37), 43 °C/10 s (W43) or 60 °C/5 s (W60). With the W60 treatment, there were greater values (P less then 0.05) for VCL (83.93 ± 3.6 μm/s) and ALH (3.00 ± 0.2 μm) than freezing and with the C group, and greater values (P less then 0.001) for PM (35.33 ± 2.5 %) than with the W43 treatment. In Experiment 2, the fertilizing capacity of vitrified and frozen sperm was assessed utilizing heterologous IVF procedures, using cattle oocytes. Vitrification resulted in greater values (P less then 0.05) than freezing for the number of bound sperm (1.36 ± 0.3 and 0.69 ± 0.2, respectively). There were no differences between frozen or vitrified sperm in pronuclear formation (26 hours post-insemination - hpi; 14.08 ± 4.2 % and 22.78 ± 4.8 %, respectively) or cleavage rate (32.77 ± 4.3 % and 39.66 ± 4.6 %, respectively). In conclusion, vitrified stallion sperm warmed in a water bath at 60 ºC had the capacity to penetrate cattle oocytes, leading to pronuclear formation and hybrid embryo cleavage after heterologous IVF.This study evaluated visible and near-infrared spectroscopy (Vis-NIRS) to authenticate barley-finished beef using different discrimination approaches. Dietary grain source (barley, corn, or blend-50% barley/50% corn) did not affect (P > 0.05) meat quality but influenced (P 94% with PLS-DA and radial/L-SVM, and approximately 90% with PLS-DA and L-SVM, respectively. Ground LT samples were classified with ≤70% overall accuracy. Vis-NIRS measurements on fat and intact LT have potential to discriminate between corn and barley-fed beef.
Colorectal cancer (CRC) is one of the most common cancers worldwide. Corylin is an isoflavone extracted from Cullen corylifolium (L.) Medik., which is widely used anti-inflammatory and anticancer in Asian countries. Signal transducer and activator of transcription 3 (STAT3) plays an important role in the occurrence and development of CRC.
To analyze the antitumor activity of corylin in CRC and to elucidate its molecular mechanisms of action.
The human CRC cell lines HCT116, RKO, and SW480 and immunodeficient mice were used as models to study the antitumor effect of corylin. The potent anti-proliferative, anti-migration and proapoptotic effects of corylin were observed by cell viability, colony formation assays, wound-healing migration assay, and cell apoptosis assay. Immunostaining analysis and western blot analysis revealed inhibition of the STAT3 signaling axis.
We found that corylin could significantly reduce the viability and stimulate apoptosis in human CRC cells in a dose-dependent manner. Corylin decreased the expression levels of P-STAT3 and STAT3 target proteins, such as myeloid cell leukemia-1(MCL-1), Survivin, VEGF and B-cell lymphoma 2 (BCL-2). It also upregulated the expression levels of the proapoptotic proteins BCL-2-associated X protein (BAX) and Cl-caspase 3. Moreover, corylin reduced the nuclear localization of STAT3. Furthermore, corylin inhibited the growth of the tumor in CRC mouse models.
Our findings provide convincing results that could support the role of corylin in the treatment of CRC through inhibiting the STAT3 pathway. It is conceivable that corylin should be further explored as a unique STAT3 inhibitor in antitumor therapy.

Image registration is performed on the stained sections by affinely aligning them using auxiliary markers, followed by image segmentation to determine muscle fibres and the extracellular matrix in each section, with particular regard to the continuity of the fibres through the stack. With this information, 3D virtual tissue samples are reconstructed, discretised, and associated with appropriate non-linear elastic anisotropic material models. While the gross anatomy is directly obtained from the images, the local directions of anisotropy were determined by the use of an analogy with steady state diffusion. The influence of the number of histological sections considered for reconstruction on the numerically simulated mechanical response of the virtual tissue samples is then studied. The results show that muscle tissue is fairly heterogeneous along the fascicles, and that transverse isotropy is inadequate in describing their material symmetry at the typical length scale of a fascicle.
