Previously we identified B-cell lineage leukemic lymphoblasts as a new expression site for subunit A of blood coagulation factor XIII (FXIII-A). On the basis of FXIII-A expression, various subgroups of B-cell precursor acute lymphoblastic leukemia (BCP-ALL) can be identified. Fifty-five children with BCP-ALL were included in the study. Bone marrow samples were obtained by aspiration and the presence of FXIII-A was detected by flow cytometry. G-banding and fluorescent in situ hybridization was performed according to standard procedures...

Liver X receptor (LXR) activation exerts an anti-tumor effect. However, whether the tumor LXR expression has prognostic significance in hepatocellular carcinoma (HCC) patient has not been addressed yet. Primary HCC and the adjacent non-tumor tissues were obtained from 169 patients who underwent routine curative surgical treatment. All patients were followed for prognosis analyses. Tumor LXR was detected by immunohistochemical analysis. In in vitro study, several HCC cell lines were cultured for cellular protein detection of LXR and other cytokines, including nuclear factor kappa (NFκB), Matrix metalloproteinases 2 and 9 (MMP-2 and -9)...

Long Non-coding RNAs (lncRNAs) refer to all non-protein coding transcripts longer than 200 nucleotides. Their critical roles in different biological pathways have been already well established. Altered expression of lncRNAs can be involved in the cancer initiation and/or progression. Since patients with hepatocellular carcinoma (HCC) are usually diagnosed in late stages, developing diagnostic methods seems to be essential. In this study, the expression levels of different lncRNAs were systematically analysed in different genomic and transcriptome datasets...

Positive association between telomere length and mitochondrial DNA (mtDNA) copy number were introduced in healthy and patients with psychiatric disorder. Based on frequent genetic changes of telomere and mitochondria in colorectal carcinomas (CRC), we studied their clinical characteristics and their association in colorectal carcinogenesis. DNA was extracted from 109 CRCs, 64 colorectal tubular adenomas (TAs), and 28 serrated polyps (SPs), and then, telomere length and mtDNA copy number were analyzed in these legions by using a real-time PCR assay...

Deregulation of the cell cycle regulating genes is common in urothelial bladder carcinoma (UBC). We aimed to examine the prognostic significance of ki-67, p53, p63 and cyclinD1expression in UBC and to identify optimal cut-off points to help identifying patients at high risk of tumor recurrence. We evaluated the immunohistochemical expression of ki-67, p53, p63 and cyclinD1 in 100 UBCs. The conventional and the classification and regression trees-guided (CART-guided) methods were utilized to determine the independent predictors of tumor recurrence...

Triple-negative breast cancer (TNBC) is associated with aggressive tumor behavior, poor prognosis and BRCA1 mutations. There are limited data regarding TNBC among Algerian women. In this study, we sought to determine clinical and tumor characteristics associated with TNBC. We also screened for the prevalence of BRCA1 mutations in unselected cohort of TNBC patients. Clinical and tumor characteristics data of 877 breast cancer patients diagnosed between 2011 and 2015, were collected from cancer registry of public hospital of Rouiba...

Follicular thyroid carcinomas (FTCs) are the second most common malignant neoplasia of the thyroid and in general its prognosis is quite favorable. However, the occurrence of metastases or non-responsiveness to radioiodine therapy worsens the prognosis considerably. We evaluated immunohistochemically the expression of hypoxia-associated proteins by hypoxia-induced factor 1α (HIF-1α), the stroma-remodeling marker Tenascin C, as well as markers for the epithelial-mesenchymal transition (EMT), namely E-cadherin and slug in a series of 59 sporadic FTCs...

The risk of venous thromboembolism (VTE) is increased in patients with cancer. However, the role of tumor markers as potential indicators of increased risk of VTE is still undetermined. In this retrospective observational case control study, levels of the tumor markers CEA, CA 19-9 and CA 125 in patients with colorectal, pancreatic, and ovarian cancer respectively, who were admitted to two community hospitals between January 2001 and December 2011, were compared between patients who were VTE positive and those who were VTE negative...

Borderline tumors (BOT) of the ovary account for 10% to 20% of ovarian neoplasms. Like ovarian cancer, BOT encompass several different histological subtypes (serous, mucinous, endometrioid, clear cell, transitional cell and mixed) with serous (SBOT) and mucinous (MBOT) the most common. Current hypotheses suggest low-grade serous carcinoma may develop in a stepwise fashion from SBOT whereas the majority of high grade serous carcinomas develop rapidly presumably from inclusion cysts or ovarian surface epithelium...

BSND protein, which is involved in chloride transport, is expressed in normal kidney and the inner ear and is known as an immunohistochemical marker for chromophobe renal cell carcinoma (RCC) and renal oncocytoma; however, other organs and tumor types exhibiting BSND expression have not yet been reported. In this study, we investigated the expression of BSND using data from the Cancer Genome Atlas (TCGA) database and by performing immunohistochemical analyses. As a result, we found that BSND was also expressed in the striated duct cells of normal salivary glands...

Recent studies have provided considerable evidence to support the hypothesis that tumor stroma plays a crucial role in the induction of immune tolerance to human cancers. Here, we investigated the contribution of reactive stromal tumor-associated fibroblasts (TAFs) and microvessels to the immunosuppressive factor indoleamine 2,3-dioxygenase (IDO) expression in the ESCC microenvironment. The immunohistochemical (IHC) analyses demonstrated a significant increased densities of TAFs and microvessels in the ESCC stroma, double IHCs showed that these increased TAFs and microvessels were with a high proliferation activity...

Estrogen and progesterone receptors are possible markers for suggesting a mammary origin of metastatic carcinoma, but are useless in cases of triple negative breast cancers (TNBC). Five other potential markers of breast origin were investigated on tissue microarrays in a series of TNBCs showing keratin 5 expression, consistent with a basal-like phenotype. GATA-3 staining was observed in 82 of 115 triple negative cases (71.3%) including 23 cases with >5% staining. Mammaglobin staining was detected in 30 cases (26...

Transmembrane protease serine 4 (TMPRSS4), a type-II transmembrane serine protease, is involved in the development and progression of wide range of tumors. However, the biological role of TMPRSS4 in prostate cancer remains obscure. Here, we investigated the effect of TMPRSS4 on proliferation and migration in prostate cancer and potential mechanisms. Our findings demonstrated over-expression of TMPRSS4 promoted the PC3 prostate cancer cells migration, which could be reversed by TMPRSS4 silencing. TMPRSS4 induced TWIST1 expression and followed progression of EMT along with upregulation of N-cadherin and downregulation of E-cadherin via STAT3 phosphorylation...

Homeobox (HOX) transcription factors and NOTCH signaling pathway are critical regulators of stem cell functions, cell fate in development and homeostasis of gastrointestinal tissues. In the present study, we analyzed cross talk between NOTCH pathway and HOX genes through assessment of probable correlation betweenMAML1 and MEIS1 as the main transcription factor of NOTCH pathway and enhancer of HOX transcriptional machinery, respectively in esophageal squamous cell carcinoma (ESCC) patients. Fifty one ESCC cases were enrolled to assess the levels of Meis1 and Maml1 mRNA expression using real-time polymerase chain reaction (PCR)...

Randomized trials in advanced biliary tract cancer (BTC) did not show benefit of cetuximab addition over chemotherapy. This is probably due to the lack of predictive biomarkers. The aim of this study was to explore possible predictive factors. Between 2009 and 2014, 57 patients were treated in 3-week cycles with cetuximab (250 mg/m(2)/week, loading dose: 400 mg/m(2)), gemcitabine (1000 mg/m(2) on day 1 and 8), and capecitabine (1300 mg/m(2)/day on days 1-14). The objective response rate (ORR), progression-free (PFS) and overall survival (OS) and the adverse events (AEs) were evaluated...

Colorectal cancer (CRC) is one of the most common cancers worldwide. DNA mismatch repair (MMR) is an evolutionarily conserved process that corrects mismatches generated during DNA replication. MMR defects were found to be associated with hereditary non-polyposis colorectal cancer (HNPCC) and a subset of sporadic colon cancers. The inheritance of common variations in MMR genes may influences individual susceptibility to the development of colorectal cancer. The purpose of the study was to evaluate the association between gene polymorphisms Glu39Gly (c...

Pseudogenes have been reported to exhibit functional roles. Amplification or overexpression of CDC28 protein kinase regulatory subunit 1B (CKS1B) was found in various human cancers. But it was known little about CKS1B pseudogene 7 (CKS1BP7), a pseudogene sharing considerable sequence identity with CKS1B. The aim of this study was to evaluate copy number alterations (CNAs) of CKS1BP7 and address its potential roles in breast cancer. We detected copy numbers of CKS1BP7 and insulin-like growth factor 1 receptor (IGF1R) using quantitative multi-gene fluorescence in situ hybridization (QM-FISH) technique, compared their status in both invasive carcinoma and ductal carcinoma in situ (DCIS) components within the same tumors, and investigated the associations of CNAs with tumor features and patients outcomes...

An important question in systems biology is what role the underlying molecular mechanisms play in disease progression. The relationship between chronic pancreatitis and pancreatic cancer needs further exploration in a system view. We constructed the disease network based on gene expression data and protein-protein interaction. We proposed an approach to discover the underlying core network and molecular factors in the progression of pancreatic diseases, which contain stages of chronic pancreatitis and pancreatic cancer...

Large tumor suppressor (LATS) is an important member of the Hippo pathway which can regulate organ size and cell proliferation. However, very little is known about the expression and clinical significance of LATS in lung cancer especially from this part of the world. We elucidated the frequency of LATS1 &LATS2 promoter hypermethylation (by methylation-specific PCR) and expression (by real-time PCR) in sixty nine (n = 69) Non-Small Cell Lung Cancer (NSCLC) patients and their corresponding normal lung tissue samples...
