Epithelia-mesenchymal transition (EMT) is critical for invasion and metastasis of esophageal carcinoma. Gli1, a transcriptional factor in Hedgehog pathway, is correlated with EMT, invasion and metastasis of tumors. However, its role in esophageal cancer is still unknown. Bioinformatics analysis revealed relationship between microRNA (miR)-361 and 3'-UTR of Gli1 gene. This study thus investigated the role of miR-361 and Gli1 in invasion and metastasis of esophageal cancer. Both tumor and adjacent tissues were collected from 58 esophageal cancer patients to test the expressions of miR-361 and Gli1, the relationship of which was confirmed by dual-luciferase reporter gene assay...

Preclinical studies have attributed 3,3',5-triiodo-L-thyronine (T3) a direct negative effect on tumor progression, as well as chemosensitizing, differentiating and immunomodulatory properties. On the other hand, L-thyroxine (T4), via a thyroid hormone receptor on plasma membrane integrin αvβ3, promotes solid tumor growth and neoangiogenesis, therefore lowering endogenous T4 reduces tumor growth rate. We present the case of two patients with metastatic triple negative breast cancer and metastatic pancreatic cancer respectively, who benefit of the sole treatment with antithyroid drugs and exogenous administration of T3 (liothyronine)...

BACKGROUND: Ovarian cancer is frequently diagnosed at an advanced stage and 70% of patients experience recurrence months to years from initial diagnosis. The expression of paraneoplastic antigens can result in the occurrence of onconeural autoantibodies in ovarian cancer that may be associated with neurological disorders that are clinically manifested in patients before diagnosis of ovarian cancer. These paraneoplastic antigens can serve as excellent biomarkers not only for early detection but also for monitoring ovarian cancer recurrence...

MicroRNAs are a class of small non-coding RNA molecules that play crucial roles in the initiation and progression of lung cancer. This study was undertaken to investigate the expression and roles of miR-186 in lung cancer. Ectopic expression experiments demonstrated that miR-186 functions as a tumor suppressor. Bioinformatic predictions, a luciferase reporter assay, and protein expression analysis suggested that miR-186 could inhibit the protein levels of SIRT6, a purported tumor suppressor gene. Collectively, our results indicated that miR-186 could inhibit lung cancer progression through targeting SIRT6 and that miR-186 may be a therapeutic target for lung cancer...

BACKGROUND: Although an immense effort has been made to develop novel diagnostic methods and treatment strategies for non-small cell lung cancer (NSCLC), the survival rate of this disease has remained virtually unchanged. Small non-coding RNAs called microRNAs (miRNAs) have appeared to be very promising biomarkers of cancer including NSCLC. OBJECTIVE: We investigated the expression level of six miRNAs, and subsequently we evaluated their diagnostic ability and their clinical significance...

BACKGROUND: Breast cancer is a common cancer in women of worldwide. Cancer cells with stem-like properties played important roles in breast cancer, such as relapse, metastasis and treatment resistance. Micro-RNA-155 (miR-155) is a well-known oncogenic miRNA overexpressed in many human cancers. METHODS: The expression levels of miR-155 in 38 pairs of cancer tissues and adjacent normal tissues from breast cancer patients were detected using quantitative real-time PCR...

BACKGROUND: Pancreatic adenocarcinoma (PDAC) is one of the deadliest human malignancies. Although surgery is currently the only effective treatment for PDAC, most patients survive less than 20 months after tumor resection. OBJECTIVE: The primary goal was to investigate alterations in KRAS, TP53, SMAD4 and CDKN2A/p16 in tumors from patients with exceptionally long survival after surgery. METHODS: Tumors from 15 patients with PDAC that survived more than 55 months after surgery ("LS") were analyzed for KRAS, TP53, IDH1, NRAS and BRAF using next-generation sequencing...

BACKGROUND: The study was aimed at investigating the role of PD98059 on impairing the cisplatin-resistance of ovarian cancer cells and figuring out the potential mechanism. MATERIAL AND METHODS: Treated with low dose of cisplatin (DDP), DDP-resistant ovarian cancer cells were built and named as SKOV-3/DDP. The cell viabilities of ovarian cancer cell line SKOV-3 and SKOV-3/DDP were detected using MTT assay. Wound healing assay and flow cytometry were performed to detect the migratory ability and cell cycle variation of the two cells and assess the sensibility to DDP in the two cell lines...

Impairment of vision or blindness always occurs in the progress of corneal neovascularization (CNV). CNV may cause corneal graft rejection at corneal transplant status. Thus, intervention of CNV is of concern to clinical treatment. Given minocycline was reported with inhibiting effect on CNV, our study was focused on specific effect of minocycline on CNV after corneal alkaline burn. Seventy-five male Sprague Dawley rats were randomly assigned into three groups with an equal number (25). Sodium hydroxide (NaOH) solution was used to establish corneal alkaline burn model...

BACKGROUND: Nevoid basal cell carcinoma syndrome (NBCCS) is a rare autosomal dominant disease with a complex genetic etiology. Although three causative genes (PTCH1, PTCH2, SUFU) have been identified through linkage analysis and Sanger sequencing, the genetic background of NBCCS hasn't been fully understood. METHODS: We performed a whole-exome sequencing (WES) in a Han Chinese NBCCS family and two unaffected volunteers to search for its causative gene.
