Klotho supplementation decreases blood pressure and albuminuria in mice with lupus nephritis.

Klotho deficiency is prevalent in various chronic kidney diseases. Although klotho is known to bind transforming growth factor β (TGFβ) receptor 1 to antagonize renal fibrosis, TGFβ also maintains regulatory T cells with inducing forkhead box protein P3 (FOXP3). Female New Zealand Black/White F (NZBWF1) mice were divided into two groups (n=10 for each): one group was treated with daily subcutaneous injection of klotho protein (30 μg/kg/day) for 8 weeks, and the other only received vehicle.

NF-κB suppression synergizes with E7386, an inhibitor of CBP/β-catenin interaction, to block proliferation of patient-derived colon cancer spheroids.

Dysregulated activation of the WNT/β-catenin signaling pathway is essential for the initiation and development of various cancers. E7386, a small-molecule compound, attenuates WNT signaling by blocking the interaction between β-catenin and CREB-binding protein (CBP); hence, it is regarded as a therapeutic candidate for cancers with activated WNT signaling. In the present study, we evaluated the biological characteristics associated with E7386 sensitivity by using a panel of patient-derived colon cancer spheroids.

Stemness and immune evasion conferred by the TDO2-AHR pathway are associated with liver metastasis of colon cancer.

The aryl hydrocarbon receptor (AHR) pathway modulates the immune system in response to kynurenine, an endogenous tryptophan metabolite. IDO1 and TDO2 catalyze kynurenine production, which promotes cancer progression by compromising host immunosurveillance. However, it is unclear whether the AHR activation regulates the malignant traits of cancer such as metastatic capability or cancer stemness.

Slow-Cycling Cancer Stem Cells Regulate Progression and Chemoresistance in Colon Cancer.

Cancer chemoresistance is often attributed to the presence of cancer stem cell (CSC)-like cells, but whether they are homogeneously chemoresistant remains unclear. We previously showed that in colon tumors, a subpopulation of CSC-like cells driven by TCF1 (TCF7), a Wnt-responsive transcription factor, were responsible for tumorigenicity. Here we demonstrate that the tumorigenic subpopulation of mouse cells exists in a slow-cycling state and identify a unique 22-gene signature that characterizes these slow-cycling CSC.

Extracellular vesicle-mediated EBAG9 transfer from cancer cells to tumor microenvironment promotes immune escape and tumor progression.

The antitumor immune response is a critical defense system that eliminates malignant cells. The failure of the system results in immune escape and proceeds to tumor growth. We have previously showed that estrogen receptor-binding fragment-associated antigen 9 (EBAG9) is a relevant cancer biomarker and facilities immune escape of cancers from the immune surveillance.

MicroRNA Library-Based Functional Screening Identified Androgen-Sensitive miR-216a as a Player in Bicalutamide Resistance in Prostate Cancer.

Prostate cancer is a major hormone-dependent tumor affecting men, and is often treated by hormone therapy at the primary stages. Despite its initial efficiency, the disease eventually acquires resistance, resulting in the recurrence of castration-resistant prostate cancer. Recent studies suggest that dysregulation of microRNA (miRNA) function is one of the mechanisms underlying hormone therapy resistance.

Multiple Human Tracking Using Binary Infrared Sensors.

To create a context-aware environment, human locations and movement paths must be considered. In this paper, we propose an algorithm that tracks human movement paths using only binary sensed data obtained by infrared (IR) sensors attached to the ceiling of a room. Our algorithm can estimate multiple human movement paths without a priori knowledge of the number of humans in the room.

Short hairpin RNA library-based functional screening identified ribosomal protein L31 that modulates prostate cancer cell growth via p53 pathway.

Androgen receptor is a primary transcription factor involved in the proliferation of prostate cancer cells. Thus, hormone therapy using antiandrogens, such as bicalutamide, is a first-line treatment for the disease. Although hormone therapy initially reduces the tumor burden, many patients eventually relapse, developing tumors with acquired endocrine resistance.

Amyloid precursor protein regulates migration and metalloproteinase gene expression in prostate cancer cells.

Amyloid precursor protein (APP) is a type I transmembrane protein, and one of its processed forms, β-amyloid, is considered to play a central role in the development of Alzheimer's disease. We previously showed that APP is a primary androgen-responsive gene in prostate cancer and that its increased expression is correlated with poor prognosis for patients with prostate cancer. APP has also been implicated in several human malignancies.

Association of positive EBAG9 immunoreactivity with unfavorable prognosis in breast cancer patients treated with tamoxifen.

Introduction: Breast cancer is primarily a hormone-dependent tumor that is regulated by the status of the estrogen and progesterone receptors. We previously identified EBAG9 as an estrogen-responsive gene in MCF-7 human breast carcinoma cells. Upregulation of EBAG9 expression has been observed in several malignant tumors such as advanced breast cancers, indicating that EBAG9 might contribute to tumor progression.

Amyloid precursor protein in human breast cancer: an androgen-induced gene associated with cell proliferation.

Amyloid precursor protein (APP) is a transmembrane protein that is highly expressed in brain tissue. Recently, APP has been implicated in some human malignancies, and its regulation by androgens has also been demonstrated. Such findings suggest the importance of APP in hormone-dependent breast carcinoma, but APP has not yet been examined in breast carcinoma tissues.

High sensitivity of an ELISA kit for detection of the gamma-isoform of 14-3-3 proteins: usefulness in laboratory diagnosis of human prion disease.

Background: The gamma-isoform of the 14-3-3 protein (14-3-3 gamma) is expressed in neurons, and could be a specific marker for neuronal damage. This protein has been reported as a detectable biomarker, especially in the cerebrospinal fluid (CSF) of Creutzfeldt-Jakob disease (CJD) patients by Western blotting (WB) or enzyme-linked immunosorbent assays (ELISAs). Western blotting for 14-3-3 gamma is not sensitive, and the reported data are conflicting among publications.

Total excision of a recurrent chondrosarcoma of the thoracic spine: a case report of a seven-year-old boy with fifteen years follow-up.

Study Design: A case report is presented.

Objective: To describe the surgical procedure for removal of the recurrent tumor.

Summary Of Background Data: Marginal or wide en bloc excision for recurrent chondrosarcoma is extremely difficult because of the postsurgical adhesion with surrounding soft tissues such as the dural tube.

Effects of pramipexole on the duration of immobility during the forced swim test in normal and ACTH-treated rats.

The dopamine D2/D3 receptor agonist pramipexole has clinically been proven to improve depression or treatment-resistant depression. However, the involvement of the dopamine receptor system on the effect of pramipexole on depression remains unclear. We examined the influence of pramipexole on the duration of immobility during the forced swim test in normal and adrenocorticotropic hormone (ACTH)-treated rats and further analyzed the possible role of dopamine receptors in this effect.

c-Jun NH(2)-terminal kinase mediates leptin-stimulated androgen-independent prostate cancer cell proliferation via signal transducer and activator of transcription 3 and Akt.

Obesity is associated with advanced prostate cancer. Here we demonstrate that in mouse prostate cancer TRAMP-C1 cells epididymal fat extracts from high-fat diet-fed obese mice stimulate androgen-independent cell growth more significantly than those from low-fat diet-fed lean mice or genetically obese leptin-deficient ob/ob mice in correlation with leptin concentrations. This result suggests that obesity promotes androgen-independent prostate cancer cell growth via adipose leptin.

Effects of imipramine and bupropion on the duration of immobility of ACTH-treated rats in the forced swim test: involvement of the expression of 5-HT2A receptor mRNA.

We examined the effect of chronic administration of imipramine and bupropion, monoamine reuptake inhibitors, on the duration of immobility in the forced swim test and serotonin (5-HT)(2A) receptor function in the form of 5-HT(2A) receptor mRNA levels in rats chronically treated with adrenocorticotropic hormone (ACTH). The immobility-decreasing effect of bupropion without imipramine did not influence the chronic ACTH treatment. The effect on the expression of 5-HT(2A) receptor mRNA of chronic ACTH treatment was decreased by bupropion, but not imipramine.

Adiponectin as a growth inhibitor in prostate cancer cells.

Prostate cancer is associated with obesity. However, the molecular basis of this association is not well known. Adiponectin is a major adipose cytokine that decreases in circulation in obesity and ameliorates obesity.

Adiponectin activates c-Jun NH2-terminal kinase and inhibits signal transducer and activator of transcription 3.

Adiponectin, a major adipose cytokine, plays a crucial role in the inhibition of metabolic syndrome by acting on such cell types as muscle cells and hepatocytes. Furthermore, evidence suggests that adiponectin may influence cancer pathogenesis. Adiponectin occurs in non-proteolytic (full-length adiponectin: f-adiponectin) and proteolytic (globular adiponectin: g-adiponectin) forms in various oligomeric states.
