Intramammary infections are one of the main causes of productivity loss in dairy cows. To better understand the immune system response and to avoid the use of live animals, we validated the use of isolated bovine udder as an ex situ model. Six mammary glands were collected from cows ready for culling. Three udders were perfused with Tyrode's solution and three were not-perfused. During six ... more

Embryogenesis; Epigenetics; Gene expression; X-chromosome inactivation

X-chromosome inactivation (XCI), an essential epigenetic event in female embryos, is involved in embryonic development and requires refined control mechanisms. Although studies in cattle have been contributing to the understanding of the dynamic mechanisms of XCI, no research has yet investigated XCI in elongated bovine embryos. We used qPCR to characterize the ... more

Globally, breast cancer a common disease affecting women. The epithelial cells lose their characteristic features and gain mesenchymal properties during disease progression. During transition, the intermediate filament changes status from keratin to cell-adhesive molecules. Vimentin, a glycoprotein constitutes an intermediate filament of mesenchymal cells to ... more

Fibroblast growth factors (FGFs) play important roles in angiogenesis, wound healing, embryonic development, and endocrine signaling pathways. Increasingly, recent studies have reported aberrant FGF expression in various malignancies. However, the involvement of FGFs in cervical carcinoma pathogenesis remains unclear. We aimed to investigate expression of acidic (aFGF) and basic FGF (bFGF) in ... more

Osteosarcoma is a common malignant bone tumor that mainly affects children and adolescents. Tumor necrosis factor-related apoptosis-inducing ligand (TRAIL) is a member of the tumor necrosis factor superfamily. Caspase-8 appears in the upstream of apoptosis signaling pathway among caspases. We investigated TRAIL and caspase-8 levels in osteosarcoma patients to determine their correlation with ... more

The objective of this study was to investigate the effect of downregulating long non-coding RNAs (lncRNAs) on the reversal of cisplatin resistance in CP70 ovarian cancer cells, and to identify the underlying mechanism(s) of action. An lncRNA microarray was performed to screen for downregulated lncRNAs in cisplatin-resistant CP70 cells. Expression levels of these lncRNAs were then verified in ... more

We aimed to evaluate the specificity of 12 tumor markers related to colon carcinoma and identify the most sensitive index. Bhattacharyya distance was used to evaluate the index. Then, different index combinations were used to establish a support vector machine (SVM) diagnosis model of malignant colon carcinoma. The accuracy of the model was checked. High accuracy was assumed to indicate the ... more

Kruppel-like factors (KLFs) are a group of transcriptional regulators that have recently been identified to exhibit tumor-suppressive function against various gastrointestinal cancers. The present study aims to investigate the expression patterns and prognostic value of KLF-4 in colorectal cancers (CRCs). KLF-4 levels in CRC tissues were examined via immunohistochemistry analysis, real-time ... more

Recent innovations in the genomic understanding of medulloblastomas have provided new ways to explore this highly invasive malignant brain cancer arising from the cerebellum. Among the four different medulloblastoma subgroups described to date, the sonic hedgehog (SHH) genetic pathway is the pathway activated in the tumorigenesis of medulloblastoma. SHH-related medulloblastomas are usually of ... more

Ras association domain family member 5 (RASSF5), a member of the Ras association domain family, induces cell apoptosis by phosphorylating FOXO3a, which triggers target gene BIM (pro-apoptotic factor) activation. MiR-214 is overexpressed in oral cancer tissue, indicating its possible involvement in oral cancer pathogenesis. Bioinformatics analysis has revealed a complimentary sequence between ... more
