Urothelial carcinoma is one of the most frequently diagnosed malignant tumors of the bladder and upper urinary tract, which ranks seventh in the pattern of cancer. Urothelial carcinoma of the renal pelvis is less common; but has a more aggressive clinical course and a worse prognosis than that of the bladder. This is due to the clinical and morphological features of this form of cancer, which, unlike bladder cancer, have not been studied enough. OBJECTIVE: To comparatively analyze the morphological and immunophenotypic parameters of urothelial carcinomas of the renal pelvis and bladder...

Our aim was to study the regulatory molecule networks involved in the epithelial-to-mesenchymal transition and thus promoting the early onset of metastasis in triple-negative breast cancer (TNBC). Forty pairs of human TNBC and their adjacent normal breast tissues were analyzed by real-time PCR and immunochemistry to demonstrate the correlation between the miR-205 expression and clinicopathological characteristics. In vitro, 3-(4,5-dimethyl-2-thiazolyl)-2,5-diphenyl-2-H-tetrazolium bromide assay, cell migration, and invasion assay were used to detect the cell growth and invasive ability of TNBC cells after upregulation or downregulation of miR-205 expression...

Exportin-T (XPOT) belongs to the RAN-GTPase exportin family that mediates export of tRNA from the nucleus to the cytoplasm. Up-regulation of XPOT indicates poor prognosis in breast cancer patients. However, the correlation between XPOT and hepatocellular carcinoma (HCC) remains unclear. Here, we found that high expression of XPOT in HCC indicated worse prognosis via bioinformatics analysis. Consistently, immunohistochemical staining of 95 pairs of tumors and adjacent normal liver tissues (ANLT) also showed up-regulation of XPOT...

It has been becoming increasingly clear, that epigenetic deregulation plays fundamental role in cancer. Although the understanding of molecular, genetic and transcriptional alterations involved in the initiation and progression of uveal melanoma (UM) has grown significantly in recent years, little attention has been paid to the role of epigenetic changes. In cancer, the epithelial-to-mesenchymal transition (EMT) enables trans-differentiation of epithelial tumor cells, endowing them with migratory and invasive properties...

The C-terminal binding protein 2 (CtBP2) is crucial for the activation of the Wnt/β-catenin pathway and regulates cellular processes of significance in multiple cancer cells. However, the role of CtBP2 in non-small cell lung cancer (NSCLC) remains uncertain. Our western blotting and immunohistochemistry assays revealed that CtBP2 expression was obviously increased in NSCLC tissues and cells. In addition, chi-square test and Kaplan-Meier analysis showed that overexpression of CtBP2 correlated with a more invasive tumor phenotype and poor prognosis...

BACKGROUND: The systemic inflammatory response (SIR) via host-tumor interactions has been termed the seventh hallmark of cancer, and several studies demonstrated that SIR might be a pivotal mediator for progression of cancer cachexia. The objective of this study was to clarify the correlation between sarcopenia and SIR in patients with colorectal cancer (CRC). METHODS: A total of 308 patients with CRC were enrolled in this study. Preoperative psoas muscle mass index and intramuscular adipose tissue content were evaluated using preoperative computed tomographic images, and the correlation between body composition status and several SIR markers, including C-reactive protein (CRP), serum albumin level, neutrophil-lymphocyte ratio, platelet-lymphocyte ratio, and systemic immune-inflammation index (SII) was assessed using statistical methods...

Intercellular communication is vital to the ecosystem of cancer cell organization and invasion. Identification of key cellular cargo and their varied modes of transport are important considerations in understanding the basic mechanisms of cancer cell growth. Gap junctions, exosomes, and apoptotic bodies play key roles as physical modalities in mediating intercellular transport. Tunneling nanotubes (TNTs)-narrow actin-based cytoplasmic extensions-are unique structures that facilitate direct, long distance cell-to-cell transport of cargo, including microRNAs, mitochondria, and a variety of other sub cellular components...

Purpose: In radiotherapy (RT) of brain tumors, the primary motor cortex is not regularly considered in target volume delineation, although decline in motor function is possible due to radiation. Non-invasive identification of motor-eloquent brain areas is currently mostly restricted to functional magnetic resonance imaging (fMRI), which has shown to lack precision for this purpose. Navigated transcranial magnetic stimulation (nTMS) is a novel tool to identify motor-eloquent brain areas. This study aims to integrate nTMS motor maps in RT planning and evaluates the influence on dosage modulations in patients harboring brain metastases...

Despite post-operative radio-chemotherapy, glioblastoma systematically locally recurs. Tumors contacting the periventricular zone (PVZ) show earlier and more distant relapses than tumors not contacting the PVZ. Since glioblastoma stem-like cells (GSCs) have been proposed to play a major role in glioblastoma recurrence, we decided to test whether GSC migration properties could be different according to their anatomical location (PVZ+/PVZ-). For that purpose, we established paired cultures of GSCs from the cortical area (CT) and the PVZ of glioblastoma patient tumors...

Heparanase (HPSE), a heparan sulfate-specific endo-β-D-glucuronidase, plays an important role in tumor cell metastasis through the degradation of extracellular matrix heparan sulfate proteoglycans. Suramin, a polysulfonated naphthylurea, is an inhibitor of HPSE with suramin analogues. Our objective was to analyze the HPSE involvement in gastric signet ring cell adenocarcinoma (SRCA) invasion. High expression of HPSE mRNA and protein was found in the tumor and in ascites of SRCA as well as in KATO-III cell line...

Interleukin (IL)-20 is a member of the IL-10 family of cytokines, which has been reported to participate in autoimmune inflammatory diseases. However, the potential role of IL-20 in hepatocellular carcinoma (HCC) progression has not yet been investigated. In the present study, it was observed that IL-20 mRNA and protein levels were markedly increased in the HCC tissues examined via reverse transcription-quantitative polymerase chain reaction and immunohistochemical staining. In addition, IL-20 expression was significantly associated with tumor size, metastasis, TNM stage and poor prognosis in patients with HCC...

Long non-coding RNAs (lncRNAs) have been suggested to serve important roles in the development of a number of human cancer types. An increasing amount of data has indicated that the lncRNA small ubiquitin-like modifier 1 (SUMO1) pseudogene 3 (SUMO1P3) has been involved in various types of human cancer. However, the function SUMO1P3 in the development of pancreatic cancer remains unclear. Firstly, reverse transcription-quantitative polymerase chain reaction was performed to determine the expression of SUMO1P3 in pancreatic cancer tissues and cell lines...

Colorectal cancer (CRC) is an important cause of morbidity and mortality worldwide, and is difficult to detect in its early stages. Diagnostic and prognostic biomarkers are required, which may also be the basis for improving the targeted therapy for CRC. Sirtuin 6 (SIRT6) is a member of the sirtuin family of gene regulators, which have specific functions in genomic stability, gene transcription and energy metabolism in tumorigenesis. Nicotinamide mononucleotide adenylyltransferase 2 (NMNAT2) is a metabolic enzyme which can be deacetylated by sirtuins...

Recent evidence indicates that immune cells contribute to the formation of tumor metastases by regulating the pre-metastatic niche. Whether tumor-derived factors involved in primary tumor formation play a role in metastasis formation is poorly characterized. Oxysterols act as endogenous regulators of lipid metabolism through the interaction with the nuclear Liver X Receptors-(LXR)α and LXRβ. In the context of tumor development, they establish a pro-tumor environment by dampening antitumor immune responses, and by recruiting pro-angiogenic and immunosuppressive neutrophils...

Immune checkpoint blockade using anti-PD-1 monoclonal antibodies has shown considerable promise in the treatment of solid tumors, but brain tumors remain notoriously refractory to treatment. In CNS malignancies that are completely resistant to PD-1 blockade, we found that bone marrow-derived, lineage-negative hematopoietic stem and progenitor cells (HSCs) that express C-C chemokine receptor type 2 (CCR2+ ) reverses treatment resistance and sensitizes mice to curative immunotherapy. HSC transfer with PD-1 blockade increases T-cell frequency and activation within tumors in preclinical models of glioblastoma and medulloblastoma...
