LINC00261 triggers DNA damage via the miR-23a-3p/CELF2 axis to mitigate the malignant characteristics of I-resistant papillary thyroid carcinoma cells.

Background: Long-chain non-coding RNA (LINC00261) in the treatment of papillary thyroid carcinoma (PTC) with I is still unknown despite its proven anti-tumour effect in thyroid cancer (TC) and other types of cancer.

Methods: The database and RT-qPCR were used to analyze the expression level of LINC00261 in PTC and cell lines. PTC cells resistant to I (TPC-1/R) were created through ongoing exposure to a lethal dose of I, and a subcutaneous xenotransplantation model was developed using PTC mice.

An immunochromatographic test for serological diagnosis of scrub typhus.

A fluorescent immunochromatographic test (FM-ICT) was developed for rapid detection of anti-Orientia tsutsugamushi antibodies in serum samples. The FM-ICT was constructed based on the dual-antigen sandwich method. Truncated 56 kDa outer membrane protein of O.

NCAPH is negatively associated with Mcl‑1 in non‑small cell lung cancer.

Lung cancer has a high mortality rate worldwide. Non‑SMC condensin I complex subunit H (NCAPH) has been identified to be one of the regulatory subunits of the condensin I complex, which is essential for the correct packaging and segregation of chromosomes in eukaryotes. NCAPH is abnormally overexpressed in various types of cancer.

The role of lipid rafts in the early stage of Enterovirus 71 infection.

Background/aims: Although it has been widely accepted that Enterovirus 71 (EV71) enters permissive cells via receptor-mediated endocytosis, the details of entry mechanism for EV71 still need more exploration. This study aimed to investigate the role of lipid rafts in the early stage of EV71 Infection.

Methods: The effect of cholesterol depletion or addition of exogenous cholesterol was detected by immunofluorescence assays and quantitative real-time PCR.

Serologic assay for avian-origin influenza A (H7N9) virus in adults of Shanghai, Guangzhou and Yunnan, China.

Background And Objective: To investigate serologic status for novel avian influenza A (H7N9) virus in different areas in China, we examined serum samples collected in winter of 2011 from adult population of Shanghai (eastern China), Guangzhou (southern China) and Yunnan (southwest China) for the antibody responses to this virus.

Study Design: A total of 900 stored serum samples of adult outpatients (300 samples for each area) were subjected to anti-hemagglutinin (HA) antibodies assay using enzyme-linked immunosorbent assay (ELISA) and neutralizing antibodies assay using H7N9 pseudotyped particles (H7N9pp) and authentic H7N9 virus based neutralization test.

Results: Anti-H7 antibodies were detected in 164, 186 and 123 samples from three areas above, respectively.

Japanese encephalitis virus enters rat neuroblastoma cells via a pH-dependent, dynamin and caveola-mediated endocytosis pathway.

Japanese encephalitis virus (JEV) is a mosquito-borne flavivirus and one of the most common agents of viral encephalitis. The infectious entry process of JEV into host cells remains largely unknown. Here, we present a systemic study concerning the cellular entry mechanism of JEV to B104 rat neuroblastoma cells.

Application of HBx-induced anti-URGs as early warning biomarker of cirrhosis and HCC.

Background: Hepatitis B virus (HBV) carriers are at high risk for the development of hepatocellular carcinoma (HCC), but there are no reliable markers that will identify such high-risk patients. HBV up-regulates the expression of selected genes (URGs) in the liver during chronic infection. These aberrantly expressed proteins trigger corresponding antibodies (anti-URGs) that appear prior to the detection of HCC.
