AF1q Expression Associates with CD44 and STAT3 and Impairs Overall Survival in Adenoid Cystic Carcinoma of the Head and Neck.
Abstract Salivary gland malignancies of the head and neck form a heterogeneous group. Adenoid cystic carcinomas are an aggressive entity of salivary gland malignancies characterized by frequent distant metastases and poor response to radio- and chemotherapy. AF1Q is a MLL fusion partner, which can activate Wnt and STAT3 signaling. Recently, overexpression of AF1q has been identified as a poor prognosticator in patients of different malignancies. A total of 46 patients with adenoid cystic carcinoma were immunohistochemically evaluated for expression of AF1q and clinical outcome was analyzed in this context. Additio...

High Expression of Angiopoietin-like Protein 4 in Advanced Colorectal Cancer and its Association with Regulatory T Cells and M2 Macrophages.
Abstract Colorectal cancer (CRC) is one of the most aggressive tumours in the human digestive system. Most CRC patients have poor prognosis due to metastasis and recurrence. Angiopoietin-like 4 (ANGPTL4) is involved in tumour development. Regulatory T (Treg) cells and M2 macrophages promote tumour growth and metastasis. Herein, we explored the changes of ANGPTL4 expression in CRC patients at different stages and observed whether in situ tumour-Treg and -M2 macrophages are correlated with ANGPTL4 expression. Serum ANGPTL4 (sANGPTL4) levels of 70 CRC patients and 10 healthy controls were detected by ELISA. ANGPTL4, ...

We performed an integrated analysis to identify candidate pathogenic genes of OS by using three Gene Expression Omnibus (GEO) databases (GSE66673, GSE49003 and GSE37552). GO and KEGG enrichment analysis were utilized to predict the functional annotation and potential pathways of differentially expressed genes (DEGs). The OS-specific transcriptional regulatory network was established to study the crucial transcriptional factors (TFs) which ta...

KIBRA Team Up with Partners to Promote Breast Cancer Metastasis.
Abstract Among women, breast cancer is the most frequently diagnosed cancer. Most of the breast cancers represent metastasis to distant organs at the time of diagnosis and accounts for the majority of deaths. Metastasis is characterized by many genetic aberrations including mutations, overexpression of oncogenes etc. KIBRA (KIdney/BRAin protein), a scaffolding protein is recently described as an important player in the process of invasion and metastasis. The Kidney/BRAin protein through its different domains interacts with various proteins to couple cytoskeleton arrangement, cell polarity and migration. N terminal...

lncRNA SNHG16 Exerts Oncogenic Functions in Promoting Proliferation of Glioma Through Suppressing p21.
Abstract Glioma is a malignant brain tumor that accounts for 30% of all brain tumors and 80% of malignant brain tumors. This poor clinical outcome makes the study of molecular mechanisms in glioma as an urgent subject. However, the certain mechanism remains unclear. Long non-coding RNAs (lncRNAs) plays a key role in glioma development and progression. In the present study, we aimed to explore the potential mechanisms of lncRNA SNHG16 in glioma. The levels of lncRNA SNHG16 were qualified in both glioma tissues and cell lines using qRT-PCR assay. The ability of cell proliferation was tested via CCK-8 and colony form...

Differential Analysis of lncRNA, miRNA and mRNA Expression Profiles and the Prognostic Value of lncRNA in Esophageal Cancer.
Abstract Integrative central axis of lncRNA-miRNA-mRNA plays pivotal roles in tumor development and progression. However, the regulatory role of lncRNA-miRNA-mRNA in esophageal cancer remains elusive. TCGA database was utilized to investigate the differential expression of lncRNA, miRNA and mRNA in esophageal cancer (ESCA) and normal esophageal tissues, and GEO database was used to further validate the expression profile of key genes. Differential lncRNAs in TCGA database were submitted to Starbase, and lncRNAs related to overall survival were analyzed using Kaplan-Meier and log-rank test. We found 145 lncRNAs, 11...

C-X-C Chemokine Receptor Type 7 (CXCR-7) Expression in Invasive Ductal Carcinoma of Breast in Association with Clinicopathological Features.
Abstract C-X-C chemokine receptor type 7 (CXCR-7) is an atypical receptor for chemokines whose role in different stages of carcinogenesis has been evaluated in breast cancer cell lines and animal models. Moreover, it has been demonstrated to be a target of regulation by the tumor suppressor microRNA (miR)-100. In the present study, we assessed CXCR-7 expression in 60 breast cancer patients in association with clinicopathological and demographic data of patients. We also extracted the results of our previous work on miR-100 expression in the same cohort of patients to assess the correlation between miR-100 and CXCR...

MicroRNA-182-5p Modulates Oral Squamous Cell Carcinoma Migration and Invasion Via Targeting MTSS1 Gene.
Abstract Oral squamous cell carcinoma (OSCC) characterized with invasive growth, local metastasis and later stage diagnosis was a common malignancy in head and neck region. The aim of this study was to explore the relationship between miR-182-5p and OSCC, which will contribute to find potential biomarker for OSCC metastasis. MiR-182-5p expression level was detected by the quantitative real-time PCR (qRT-PCR). Cell migration and invasion ability were examined by scratch and transwell assay. Loss-of function together with luciferase reporter assay were used to verify the miR-182-5p modulated OSCC cells migration and...

Dynamic FDG-PET/CT in the Initial Staging of Primary Breast Cancer: Clinicopathological Correlations.
In conclusion, we confirmed a significant relationship between kinetic parameters measured by dynamic PET and the routinely assessed clinicopathological factors of breast cancer: high-grade, hormone-receptor negative tumors with high proliferation rate are characterized by higher cellular FDG-uptake and FDG-phosphorylation rate. Furthermore, we found that kinetic parameters based on the dynamic examinations are probably not influenced by stromal TIL infiltration.

The Investigation of Lipoxygenases as Therapeutic Targets in Malignant Pleural Mesothelioma.
Abstract Advanced malignant pleural mesothelioma (MPM) has an extremely poor prognosis with limited chemotherapy options, therefore the identification of new therapeutic targets would aid in disease management. Arachidonic acid is metabolised by cyclooxygenase and lipoxygenase enzymes. The lipoxygenase isoenzymes 5-LOX and 12-LOX have been implicated in carcinogenesis. We aimed to examine 5-LOX and 12-LOX protein expression in a large retrospective series of mesothelioma samples. Further to this, the in vitro cytotoxic effects of lipoxygenase pathway inhibitors were investigated in mesothelioma cells. Archival sam...

Phloretin Inhibits the Human Prostate Cancer Cells Through the Generation of Reactive Oxygen Species.
Abstract Phloretin is a flavonoid with known anticancer activities. However, we do not fully understand how phloretin mitigates prostate cancer on the molecular level. In the present study, we examined changes in proliferation, colony formation, and migration after phloretin treatment in human prostate cancer cells PC3 and DU145. We measured reactive oxygen species (ROS) and gene expression. Phloretin increased ROS and suppressed cell proliferation, migration, and colony formation in both cell lines. Additionally, phloretin treatment increased oxidative stress, as demonstrated through lower antioxidant enzymes (ca...
