Abstract
Lung adenocarcinoma (LUAD) represents the most prevalent subtype of lung cancer and typically has high incidence and fatality rates. Motor neuron and pancreas homeobox 1 (MNX1) and coiled-coil domain-containing 34 (CCDC34) serve as oncogenes in multiple types of cancer. However, their role in LUAD remains to be elucidated. In the present study, bioinformatics analysis and LUAD cell lines were adopted to examine the expression of MNX1 and CCDC34. The proliferation, migration and invasion abilities of A549 cells were determined using Cell Counting Kit-8, colony formation, wound-healing and Transwell assay, and flow cytometry was conducted to assess cell cycle distribution and apoptosis. The interaction between MNX1 and CCDC34 was verified by luciferase reporter and chromatin immunoprecipitation assays. In addition, an in vivo animal model of LUAD was established for validation. The results demonstrated that both MNX1 and CCDC34 were upregulated in LUAD cell lines. MNX1 knockdown significantly suppressed cell proliferation, migration and invasion, hindered cell cycle progression and promoted cell apoptosis in vitro and inhibited tumor growth in vivo. However, the antitumor effect of MNX1 knockdown was weakened by simultaneous CCDC34 overexpression in vitro. In terms of mechanism, MNX1 was demonstrated to directly bind to the CCDC34 promoter and transcriptionally activate CCDC34 expression. In conclusion, the present study highlighted a critical role of the MNX1/CCDC34 axis in regulating LUAD progression, providing novel therapeutic targets for LUAD treatment.

Abstract
BACKGROUND The present study explored the expression of coiled-coil domain-containing 34 (CCDC34) in cervical cancer (CC) and its prognostic value. MATERIAL AND METHODS GEPIA and Oncomine cancer databases were mined to predict the CCDC34 differential expression level between a CC group and a normal group. Immunohistochemistry was performed to examine the CCDC34 expression in 67 CC and corresponding adjacent tissues. CD31 and vascular endothelial growth factor (VEGF) were stained to reflect tumor angiogenesis in 67 CC tissues. Kaplan-Meier univariate and Cox multivariate survival analysis were done to evaluate the correlation between CCDC34 expression and prognosis of CC patients. RESULTS Both GEPIA and Oncomine cancer databases mining results revealed that CCDC34 was more highly expressed in the CC group than in the normal group (all P<0.05). Our immunochemical staining data showed that CCDC34 expression was dramatically higher in CC than in adjacent normal tissues (71.6 vs. 20.9%; P<0.001). High expression of CCDC34 was strongly associated with histological grade (P=0.022), lymph node metastasis (P=0.044), and FIGO stage (P=0.002). Furthermore, patients with CCDC34-positive expression had much more MVD than those with CCDC34-negative expression (P<0.001). Kaplan-Meier survival analysis showed that CCDC34-positive expression was associated with worse overall survival (OS) (P=0.004) and disease-free survival (DFS) (P=0.005). Additionally, Cox multivariate analysis revealed that CCDC34 was an independent unfavorable prognostic parameter of DFS and OS (P=0.040 and 0.039, respectively). CONCLUSIONS High expression of CCDC34 is an independent unfavorable prognostic parameter for OS and DFS of CC patients, which was strongly associated with tumor angiogenesis.

Abstract
BACKGROUND Coiled-coil domain containing 34 (CCDC34) promotes cell proliferation and invasive properties in human cancer. The aim of this study was to compare the expression of CCDC34 in pancreatic adenocarcinoma with normal pancreatic tissue, and to evaluate the prognostic significance of CCDC34 expression in patients with pancreatic adenocarcinoma, using bioinformatics. MATERIAL AND METHODS The expression and prognostic value of CCDC34 were initially predicted using Oncomine and The Cancer Genome Atlas (TCGA) databases. Pancreatic adenocarcinoma tissue samples (N=90) and matched normal pancreatic tissues (N=90) were studied using immunohistochemistry to measure CCDC34 protein expression levels. Univariate Kaplan-Meier, and multivariate Cox analysis were used to determine the prognostic role of CCDC34 expression. RESULTS Oncomine and TCGA databases predicted that CCDC34 mRNA expression levels were significantly increased in pancreatic adenocarcinoma compared with normal pancreatic tissues (P<0.05), and that patients with increased CCDC34 mRNA expression levels had significantly lower overall survival (OS) (P=0.031). Immunohistochemistry showed that expression levels of CCDC34 protein in pancreatic adenocarcinoma were significantly increased, compared with normal pancreas (P=0.000). Patients with pancreatic adenocarcinoma with increased expression of tissue CCDC34 had significantly reduced OS compared with patients with low expression (P=0.000). Univariate and multivariate survival analysis showed that increased expression of CCDC34 was an independent predictor of poor prognosis in patients with pancreatic adenocarcinoma (all, P=0.000). CONCLUSIONS Compared with normal pancreas, CCDC34 expression was significantly increased in pancreatic adenocarcinoma, and increased CCDC34 expression was an independent predictor of poor patient prognosis.

Abstract
The coiled coil is a superhelical structural protein motif involved in a diverse array of biological functions, and the abnormal expression of the coiled-coil domain containing proteins has a direct link with the phenotype of tumor cell migration, invasion and metastasis. The aim of this study was to investigate the critical role of Coiled-coil domain-containing protein 34 (CCDC34) in bladder carcinogenesis, which has never been reported to date. Here, we found CCDC34 expression was elevated in bladder cancer tissues and cell lines. The knockdown of CCDC34 via lentivirus-mediated siRNA significantly suppressed bladder cancer cells proliferation and migration, and induced cell cycle arrest at G2/M phase and increased apoptosis in vitro. In addition, CCDC34 knockdown suppressed bladder tumor growth in nude mice. Moreover, CCDC34 silencing decreased the phosphorylation of MEK, ERK1/2, JNK, p38 and Akt, and the expressions of c-Raf and c-Jun, indicating MAPK and AKT pathways (ERK/MAPK, p38/MAPK, JNK/MAPK and PI3K/Akt) might be involved in CCDC34 regulation of bladder cancer cell proliferation and migration. Our findings revealed for the first time a potential oncogenic role for CCDC34 in bladder carcinoma pathogenesis and it may serve as a biomarker or even a therapeutic target for bladder cancer.

Abstract
Autosomal recessive gene defects are arguably the most important, but least studied genetic causes of severe cognitive dysfunction. Homozygosity mapping in 78 consanguineous Iranian families with nonsyndromic autosomal recessive mental retardation (NS-ARMR) has enabled us to determine the chromosomal localization of at least 8 novel gene loci for this condition. Our data suggest that in the Iranian population NS-ARMR is very heterogeneous, and they argue against the existence of frequent gene defects that account for more than a few percent of the cases.

Abstract
Mutations in the type VII collagen gene (COL7A1) cause autosomal recessive and autosomal dominant inherited dystrophic epidermolysis bullosa (DEB). We report a family with three individuals who present blistering, scarring, hypo- and hyperpigmentation, and nail dystrophy suggestive for DEB. Whereas father and son carry a 5;13 translocation, the daughter shows a normal karyotype. Segregation analysis revealed that all affected family members inherited the same COL7A1 allele. Mutation analysis disclosed a heterozygous missense mutation, c.6227G > A (p.G2076D), in COL7A1 in all affected individuals. Delineation of the translocation breakpoints showed that the ERBB2IP (erbb2 interacting protein or Erbin) gene is disrupted in 5q13.1 and GPC6 in 13q32. GPC6 encodes glypican 6 belonging to a family of cell surface heparan sulfate proteoglycans. The binding partners of Erbin, BP230 (BPAG1) and the integrin beta4 subunit, both involved in hemidesmosome (HD) function, and the presence of Erbin in HD suggested that it plays a role in establishment and maintenance of cell-basement membrane adhesions. However, loss of function of one ERBB2IP copy or expression of a putative novel ERBB2IP fusion protein did not apparently modulate the DEB phenotype in both translocation patients. Nonetheless, one cannot yet exclude that ERBB2IP is a candidate for human blistering disorders such as epidermolysis bullosa.

Abstract
Zimmermann-Laband syndrome (ZLS) is a rare disorder characterized by gingival fibromatosis, abnormalities of the nose and/or ears, and absence or hypoplasia of nails or terminal phalanges of hands and feet. Other more variable features include hyperextensibility of joints, hepatosplenomegaly, mild hirsutism, and mental retardation. The genetic basis of ZLS is unknown; autosomal dominant inheritance has been suggested. We report an apparently balanced chromosomal aberration, 46,XX, t(3;8)(p13-p21.2;q24.1-q24.3), in a family with an affected mother and daughter. Using fluorescence in situ hybridization with BAC clones, we refined the breakpoints to 3p21.2 and 8q24.3 and, thereby, narrowed down both breakpoint regions to approximately 1.5 Mb. Our data provide additional support to the assumption that ZLS follows autosomal dominant inheritance. The 3;8 translocation described here represents a powerful resource to identify the causative gene for ZLS that maps most likely to one of the breakpoints.
