BACKGROUND AND AIM Hepatocellular carcinoma (HCC) is one of the most deadly tumors. Transarterial chemoembolization (TACE) is effective for unresectable HCC. In recent years, miRNAs have been proposed as novel diagnostic and prognostic tools for HCC. This study aimed to identify whether microRNAs (miRNAs) can serve as biomarkers to reliably predict outcome(More)
As a tumor suppressor, breast cancer susceptibility gene 1 (BRCA1) plays a pivotal role in maintaining genomic stability. A functional rs799917 T>C polymorphism located in the BRCA1 coding sequence could influence miR-638-mediated regulation of BRCA1 expression. Therefore, we examined the association between this polymorphism and esophageal squamous cell(More)
Long noncoding RNA (lncRNA) HOX transcript antisense RNA (HOTAIR), which could induce genome-wide retargeting of polycomb-repressive complex 2, trimethylates histone H3 lysine-27 (H3K27me3) and deregulation of multiple downstream genes, is involved in development and progression of esophageal squamous cell carcinoma (ESCC). We hypothesized that the(More)
As an oncoprotein, MDM4 plays a key part in P53 tumor suppressor pathway through negatively regulating P53 function. It has been reported that an rs4245739 A>C polymorphism locating in the MDM4 3'-untranslated region creates a miR-191 target site and results in decreased MDM4 expression. Therefore, we investigated the association between this polymorphism(More)
Long noncoding RNA (lncRNA) HOX transcript antisense RNA (HOTAIR) acts as an oncogene in gastric cancer development. HOTAIR could induce genome-wide retargeting of polycomb-repressive complex 2, trimethylates histone H3 lysine-27 (H3K27me3) and deregulation of multiple downstream genes. Additionally, as the ceRNA of miR-331-3p, HOTAIR may modulate HER2(More)
A functional rs4245739 A>C single nucleotide polymorphism (SNP) locating in the MDM43'-untranslated (3'-UTR) region creates a miR-191-5p or miR-887-3p targeting sites. This change results in decreased expression of oncogene MDM4. Therefore, we examined the association between this SNP and small cell lung cancer (SCLC) risk as well as its regulatory function(More)
MALAT1, a highly conserved long noncoding RNA, is deregulated in several types of cancers. However, its role in esophageal squamous cell carcinoma (ESCC) and its posttranscriptional regulation remain poorly understood. In this study we provide first evidences that a posttranscriptional regulation mechanism of MALAT1 by miR-101 and miR-217 exists in ESCC(More)
Short leukocyte telomere length has been associated with significantly increased risk of esophageal cancer. A previous genome-wide association study demonstrated that four SNPs (rs398652 on 14q21, rs621559 on 1p34.2, rs6028466 on 20q11.22 and rs654128 on 6q22.1) were associated with leukocyte telomere length in Caucasians. However, the role of these genetic(More)
As a DNA repair protein, Flap endonuclease 1 (FEN1) plays crucial parts in preventing carcinogenesis. Two functional germ line variants (-69G > A and 4150G > T) in the FEN1 gene have been associated with DNA damage levels in coke oven workers and lung cancer risk in general populations. However, the role of these genetic variants on gastrointestinal cancer(More)
BACKGROUND AND PURPOSE Nitric oxide (NO), mainly synthesized by inducible nitric oxide synthase (NOS2) in pathological conditions, plays an important role in cytotoxicity, inflammation and fibrosis. Elevations in exhaled NO after thoracic radiation have been reported to predict radiation-induced lung injury (RILI). This study examined whether genetic(More)
