The noncanonical function of borealin, a component of chromosome passenger complex, promotes glycolysis via stabilization of survivin in squamous cell carcinoma cells.

The chromosome passenger complex (CPC) is a kinase complex formed by Aurora B, borealin, survivin and inner centromere protein (INCENP). The CPC is active during mitosis and contributes to proper chromosome segregation via the phosphorylation of various substrates. Overexpression of each CPC component has been reported in most cancers.

Establishment of repeated liver biopsy technique in experimental mice.

Biopsy is a commonly used method for determining pathological diagnoses by directly using human tissues and cells. Biopsies are widely used to determine disease progression and treatment efficacy. Although organs and tissues are usually obtained by sacrifice during animal experiments, it is theoretically possible to use the same biopsy techniques in humans.

CD4 T-cell-dependent differentiation of CD23 follicular B cells contributes to the pulmonary pathology in a primary Sjögren's syndrome mouse model.

Introduction: Primary Sjögren's syndrome (pSS) is a systemic autoimmune disease that affects the function of exocrine glands, such as the lacrimal and the salivary glands. Extraglandular lesions and malignant lymphoma also occur during the progressive stage of pSS. We have, herein, focused on the pulmonary lesions of pSS and have aimed clarifying their pathophysiological mechanism by comparing the glandular with the extraglandular lesions observed in a mouse model of pSS.

Successful induction of pseudopregnancy using sonic vibration in mice.

Embryo transfer (ET) is an essential reproductive technology for the production of new animal strains and maintenance of genetic resources. We developed a method, named Easy-ET, to induce pseudopregnancy in female rats by artificial stimulation using sonic vibration instead of mating with vasectomized males. This study examined the application of this method for the induction of pseudopregnancy in mice.

Cancer cell-derived novel periostin isoform promotes invasion in head and neck squamous cell carcinoma.

It recently has been reported that partial-epithelial-mesenchymal transition (p-EMT) program is associated with metastasis in head and neck squamous cell carcinoma (HNSCC). We previously have identified POSTN (which encodes periostin) as an invasion-promoting molecule in HNSCC. Interestingly, POSTN expression is frequently observed in cancer cells with higher p-EMT score by using a previous single-cell transcriptomic data of HNSCC cases.
