Triple-negative breast cancer is a highly aggressive type of mammalian carcinoma. It is defined by a rather weak expression of estrogen-, progesterone- and Her2-receptor, and is thus difficult to treat, resulting in low disease-free and overall survival rates of the affected patients. Hence it is important to find new therapeutic options. To this aim we analysed the incidence of some molecules from different signal transduction cascades by immunohistochemistry, which are known to correlate with triple-negative breast cancer, and correlated the expression of these molecules to different tumour traits, such as size, grading, menopausal stage, histology, lymph node affection, remote metastasis formation, and to the incidence of local and lymph node recurrence and metastasis by statistical analysis...

Prohibitin (PHB) is a multifunctional protein conserved in eukaryotic systems and shows various expression levels in tumor cells. However, regulation of PHB is not clearly understood. Here, we focused on the regulation of PHB expression by Wnt signaling, one of dominant regulatory signals in various leukemic cells. High mRNA levels of PHB were found in half of clinical leukemia samples. PHB expression was increased by inhibition of the MAPK pathway and decreased by activation of EGF signal. Although cell proliferating signals downregulated the transcription of PHB, treatment with lithium chloride, an analog of the Wnt signal, induced PHB level in various cell types...

Renal fibrosis is the final common pathway of all progressive renal disease. Excessive and chronic activation of the Wnt/β-catenin signaling pathway results in chronic kidney disease (CKD) progression. To mimic CKD, the present study used 5/6-nephrectomized rats, and alterations in kidney histology, expression of β‑catenin and renal cell apoptosis were assessed. In addition, mesangial cells were cultured in vitro and transfected with β‑catenin siRNA to evaluate the effect of blocking Wnt/β‑catenin signaling on cell apoptosis and the expression of markers of renal fibrosis...

Annexin A2 is a member of the Annexin family that acts as a Ca2+-dependent phospholipid and membrane binding protein, which is associated with the survival and spread of multiple neoplasms. However, the function of Annexin A2 in ovarian cancer progression remains unclear. In this study, we aimed to investigate the role and underlying molecular mechanism of Annexin A2 in cell proliferation and invasion in ovarian cancer. We found that the mRNA expression of Annexin A2 was upregulated in ovarian cancer tissues and cell lines...

The aberrant expression of miR-30d has been reported in several types of human malignancies. However, its biological function in colorectal cancer (CRC) remains largely unknown. In this study, we identified that miR‑30d was significantly downregulated in CRC tissues compared to that observed in normal controls as detected by RT‑qPCR analysis. Downregulation of miR‑30d was significantly associated with aggressive clinicopathological parameters including tumor differentiation, invasive depth, TNM stage, lymph node metastasis, distant metastasis, and poor prognosis...

Human colorectal cancer stem cells (CSCs) are tumour initiating cells that can self-renew and are highly tumorigenic and chemoresistant. While genetic mutations associated with human colorectal cancer development are well-known, little is known about how and whether epigenetic factors specifically contribute to the functional properties of human colorectal CSCs. Here we report that the KDM3 family of histone demethylases plays an important role in tumorigenic potential and survival of human colorectal CSCs by epigenetically activating Wnt target gene transcription...

Desmoid-type fibromatosis is a sarcoma subtype that gathers some singular characteristics, making it a difficult challenge to face in clinical practice. Despite its excellent survival prognosis, these tumors may be unpredictable, ranging from an asymptomatic indolent course to persistent, local, and extended recurrences that significantly impair quality of life. Although surgery was initially considered the first elective treatment, collected published data during the past few years are now pointing to the "wait and see" approach as a reasonable initial strategy because many patients can live a long life with the disease without having symptoms...

YAP1 (Yes-associated protein 1) transcriptional coactivator is a downstream gene of the Hippo signaling pathway, which controls cell proliferation and differentiation. YAP1 plays a significant role in the regulation of cartilage and bone development. However, the molecular mechanism by which YAP1 regulates chondrocyte differentiation remains to be elucidated. Immunofluorescent staining was used to visualize the localization of YAP1 expression in the mouse chondroprogenitor ATDC5 cell line. ATDC5 cells with lentivirus-vector-mediated YAP1 overexpression and knockdown were established...

Pulmonary enteric adenocarcinoma (PEA) is a rare variant of pulmonary adenocarcinoma; it is sometimes difficult to discriminate between PEA and metastatic colorectal carcinoma (MCRC) because of their morphological and immunohistochemical resemblance. Here, we conducted clinicopathological, immunohistochemical, and mutational analyses of PEA with special focus on its differentiation from MCRC. We comparatively analyzed eight surgically resected PEA tumors (7 patients) and 20 cases of MCRC. Patients were aged 43-77years (average age, 64...

In regenerating liver, hepatocytes accumulate lipids before the major wave of parenchymal growth. This transient, regeneration-associated steatosis (TRAS) is required for liver recovery, but its purpose is unclear. The tumor suppressor PTEN is a key inhibitor of the AKT-mTOR axis that regulates growth and metabolic adaptations after hepatectomy. In quiescent liver, PTEN causes pathological steatosis when lost, while its role in regenerating liver remains unknown. Here, we show that PTEN downregulation promotes liver growth in a TRAS-dependent way...

Increased expression of microRNA-500a (miR-500a) has been reported in the serum of hepatocellular carcinoma (HCC) patients. However, the biological effects and mechanisms of miR-500a in hepatoma cells remain unclear. In this study, we found that miR-500a expression was up-regulated in HCC cell lines and tissues, and that high levels of miR-500a was associated with poor prognosis. We found that miR-500a upregulation promoted migration and invasion in two hepatoma cell lines, HCCLM3 and SMMC7721, while miR-500a downregulation had the opposite effect...

CD4(+) Foxp3(+) regulatory T cells (Treg) include differentiated populations of effector Treg characterized by the expression of specific transcription factors. Tumors, including intestinal malignancies, often present with local accumulation of Treg that can prevent tumor clearance, but how tumor progression leads to Treg accumulation is incompletely understood. Here using genetically modified mouse models we show that ablation of E-cadherin, a process associated with epithelial to mesenchymal transition (EMT) and tumor progression, promotes the accumulation of intestinal Treg by the specific accumulation of the KLRG1(+) GATA3(+) Treg subset...

The cancer stem cell (CSC) theory depicts a special population within the cancer mass that self-renew and sustain the cancer, even if the other cells were eliminated by therapies. How CSCs acquire these unique traits is still unclear. Crumbs homolog 3 (CRB3), a member of the CRB polarity complex, has been reported to act as a tumor suppressor. Here, we detected significantly lower or negative CRB3 expression in human breast cancer tissues. Knockdown of CRB3 generated non-tumorigenic, immortalized breast epithelial cell line MCF 10A with CSC properties...

In rodents, disruption of mother-infant attachment induced by maternal separation (MS) is associated with recognition memory impairment and long-term neurobiological consequences. Particularly stress-induced modifications have been associated to disruption of cadherin (CDH) adhesion function, which plays an important role in remodeling of neuronal connection and synaptic plasticity. This study investigated the sex-dependent effect of MS on recognition memory and mRNA levels of classical type I and type II CDH and the related β -catenin (β -Cat) in the hippocampus and prefrontal cortex of late adolescent mice...

Human synovial fluid-derived mesenchymal stem cells (SFMSCs) have great potential for cartilage induction and are promising for cell-based strategies for articular cartilage repair. Many long non-coding RNAs (lncRNAs) regulate chondrogenesis of MSCs. We hypothesized that the divergent lncRNA ZBED3-AS1, which binds locally to chromatin, could promote the expression of zbed3, a novel Axin-interacting protein that activates Wnt/β-catenin signaling, involved in chondrogenesis. However, the function of ZBED3-AS1 in SFMSCs is unclear...

Cancer stem cells (CSCs) play a central role in the development of cancer. The canonical Wnt/β-catenin pathway is critical for maintaining stemness of CSCs. Phytochemicals from dietary compounds possess anti-CSCs properties and have been characterized as promising therapeutic agents for the prevention and treatment of many cancers. To date, the involvement and function of miR-19, a key oncogenic miRNA, in regulating Wnt/β-catenin pathway and lung CSCs has not been defined. Meanwhile, the effect of sulforaphane (SFN) on lung CSCs also remains to be elucidated...

Shigella dysenteriae (S.dysenteriae) the causative agent of bacillary dysentery invades the human colonic epithelium resulting in severe intestinal inflammatory response and epithelial destruction. However, the mechanism by which S.dysenteriae infection regulates proinflammatory cytokines during intestinal inflammation is still obscure. In this study, we evaluated whether the interaction of β-catenin and NF-κB regulates proinflammatory cytokines TNF-α and IL-8 by modulating GSK-3β activity during S.dysenteriae infection in rat ileal loop model...
