The effect and mechanism of miR-607/CANT1 axis in lung squamous carcinoma.

Lung squamous carcinoma (LUSC) is the second most frequent subtype of non-small cell lung cancer. Rarely gene alterations are identified in LUSC. Therefore, identifying LUSC-related genes to explain the relevant molecular mechanism is urgently needed.

Dicer1 dysfunction promotes stemness and aggression in endometrial carcinoma.

Endometrial carcinoma is one of the most common gynecological malignancies, but the molecular events involved in the development and progression of endometrial carcinoma remain unclear. Dicer1 and cancer stem cells play important roles in cell motility and survival. This study investigated the role of the let-7 family and Dicer1 in the stemness of endometrial carcinoma cells.

Mutant p53 induces EZH2 expression and promotes epithelial-mesenchymal transition by disrupting p68-Drosha complex assembly and attenuating miR-26a processing.

The tumor suppressor p53 and the transcriptional repressor Enhancer of Zeste Homolog 2 (EZH2) have both been implicated in the regulation of epithelial-mesenchymal transition (EMT) and tumor metastasis via their impacts on microRNA expression. Here, we report that mutant p53 (mutp53) promotes EMT in endometrial carcinoma (EC) by disrupting p68-Drosha complex assembly. Overexpression of mutp53 has the opposite effect of wild-type p53 (WTp53), repressing miR-26a expression by reducing pri-miR-26a-1 processing in p53-null EC cells.

[Use body fat determination instead of simple body composition parameters evaluate the risk of metabolic syndrome in Fuzhou adults].

Objective: To compare the application of two different definitions of MS (IDF2005 and ATPIII2001) in this study population. According to IDF2005, evaluate the impact of body fat content and its distribution for the risk of metabolic syndrome.

Methods: The sample of 818 subjects measure the simple anthropometric parameters including body mass index (BMI), waist circumference, waist-hip ratio (WHR), and so on.

[Application of real-time fluorescence quantitative PCR accompanied with comparison of Delta CT for diagnosis of Down's syndrome from a single cell].

Objective: To evaluate the use of real-time fluorescence quantitative PCR (FQ-PCR) accompanied with comparison of Delta CT as a method for diagnosis of Down's syndrome from a single cell.

Methods: Single lymphocyte was isolated from the peripheral or umbilical cord blood samples of 22 clinically diagnosed Down's syndrome patients or fetus and 40 normal controls by micromanipulation techniques. Primer extension preamplification (PEP) and real-time FQ-PCR were used to amplify the S100B and DCSR1 located on chromosome 21, and GAPDH located on chromosome 12.
