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)
Papillary thyroid carcinoma (PTC) is the most common type of thyroid cancer. However, we know little of mutational spectrum in the Chinese population. Thus, here we report the identification of somatic mutations for Chinese PTC using 402 tumor-normal pairs (Discovery: 91 pairs via exome sequencing; validation: 311 pairs via Sanger sequencing). We observed(More)
Although the entire etiology of esophageal squamous cell carcinoma (ESCC) is still unclear, alcohol drinking has been identified as a major environmental risk factor. The aldehyde dehydrogenase (ALDH) superfamily members are major enzymes involved in the alcohol-metabolizing pathways. Accumulating evidences demonstrated that ALDH7A1, one of ALDH superfamily(More)
Dyregulation of autophagy is implicated in human cancers and the mechanism details remains largely unclear. Herein we report the regulatory role of miR-638 in autophagy of esophageal squamous cell carcinoma (ESCC) and breast cancer cells. We found that miR-638 overexpression promotes starvation- and rapamycin-induced autophagy. In ESCC and breast cancer(More)
OBJECTIVE Although several genome-wide association studies (GWAS) of non-cardia gastric cancer have been published, more novel association signals could be exploited by combining individual studies together, which will further elucidate the genetic susceptibility of non-cardia gastric cancer. DESIGN We conducted a meta-analysis of two published Chinese(More)
China was one of the countries with highest esophageal squamous cell carcinoma (ESCC) incidence and mortality worldwide. Alcohol drinking has been identified as a major environmental risk-factor related to ESCC. The alcohol dehydrogenase (ADH) family are major enzymes involved in the alcohol-metabolizing pathways, including alcohol dehydrogenase 1B (ADH1B)(More)
As a crucial homologous recombination repair gene, RAD52 participates in maintenance of genomic stability and prevention of tumorigenesis. Although several cancer susceptibility RAD52 single nucleotide polymorphisms (SNPs) have been identified previously, little was known on how the RAD52 SNPs are involved in glioma development in Han Chinese. Therefore, we(More)
B-cell lymphoma-2 (BCL-2) prevents apoptosis and its overexpression could promote cancer cell survival. Multiple functional BCL-2 genetic polymorphisms, such as rs2279115, rs1801018 and rs1564483, have been identified previously and might be involved in cancer development through deregulating BCL-2 expression. Therefore, we examined associations between(More)
5S rRNA plays an important part in ribosome biology and is over-expression in multiple cancers. In this study, we found that 5S rRNA is a direct target of miR-150 and miR-383 in esophageal squamous cell carcinoma (ESCC). Overexpression of miR-150 and miR-383 inhibited ESCC cell proliferation in vitro and in vivo. Moreover, 5S rRNA silencing by miR-150 and(More)
