BACKGROUND & AIMS Men have a higher incidence of hepatocellular carcinoma (HCC) than women, which is believed to partly be because of protective effects of estrogen. We sought to determine whether there were differences in levels of microRNA (miRNA) molecules between male and female HCC samples. METHODS The expression profiles of a panel of candidate(More)
UNLABELLED Deregulation of microRNAs (miRNAs) is common in advanced human hepatocellular carcinoma (HCC); however, the ones involved in early carcinogenesis have not yet been investigated. By examining the expression of 22 HCC-related miRNAs between precancerous and cancerous liver tissues, we found miR-216a and miR-224 were significantly up-regulated,(More)
Genetic tractability and easy manipulation make Caenorhabditis elegans a good model to study host-pathogen interactions. Dozens of different bacterial species can pathogenically infect C. elegans under laboratory conditions, and all of these microbes are extracellular pathogens to nematodes. Viruses, on the other hand, are obligate intracellular parasites,(More)
The hepatitis B virus (HBV) is a widespread human pathogen and chronic HBV infection is a major risk factor for hepatocellular carcinoma (HCC). The role of microRNA (miRNA) in the replication and pathogenesis was reviewed. So far none of HBV-encoded miRNA has been identified. Cellular miRNAs have shown able to regulate HBV at the transcription level either(More)
BACKGROUND Antiviral therapy by nucleoside/nucleotide analogues (NAs) effectively reduces HBV replication in chronic hepatitis B (CHB) patients. Because long-term NA treatments will eventually select for drug-resistant mutants, early detection of mutants and frequent monitoring of viral loads is crucial for successful NA therapy. Because no efficient test(More)
It is widely feared that outward FDI gradually hollows out domestic manufacturing and displaces local workers. We address this concern by drawing on exceptionally informative firm-specific data on Taiwanese multinationals in manufacturing. In particular, we assess whether repercussions at home depend on the size, location and type of outward FDI. We control(More)
The estrogen pathway has long been implicated as a tumor protector in female hepatitis B virus (HBV)-related hepatocellular carcinoma (HCC). Our previous study identified that estrogen receptor alpha (ERα) protein is downregulated in 60% of female HCC cases, via a miR-18a elevation mediated suppression of ERα translation. This study aims to delineate the(More)
A growing list of microRNAs (miRNAs) show aberrant expression patterns in hepatocellular carcinoma (HCC), but the regulatory mechanisms largely remain unclear. RNA editing catalyzed by members of the adenosine deaminase acting on the RNA (ADAR) family could target the miRNA precursors and affect the biogenesis process. Therefore, we investigate whether RNA(More)
Tumors expressing a transforming growth factor-beta type I receptor (TβRI) mutant with sequence deletions in a nine-alanine (9A) stretch of the signal peptide are reported to be highly associated with disease progression. Expression of this mutant could interfere with endogenous TGFβ signaling in the cell. However, little is known about the importance of(More)
Over the past decade the scale of higher education in China has expanded substantially. Regional development policies attempted to make use of the scale expansion as a tool to reduce the inequality of higher education among different regions with different development levels through providing the poor regions preferential treatment and support in this(More)
