Authors: Ma Q, Shao Y, Chen W, Quan C, Zhu Y, Xu X, Zhou Z, Wang S Abstract Aim: To investigate whether cervical cancer (CC) and cervical intraepithelial neoplasia (CIN) can be screened by analyzing gene expression profiling of peripheral blood. Methods: RNA-sequencing analysis of blood was performed on 11 CC patients, 21 CIN patients and 19 healthy controls (H). Fifty-nine genes were validated by quantitative real-time PCR using blood samples from 46 H, 83 CC and 32 CIN patients. Results: There were significant differences in the expression levels of six genes between CC and H, five genes between CIN and H and fou...

Authors: Deng Z, Wu J, Xu S, Chen F, Zhang Z, Jin A, Wang J Abstract Exosomes have appeared as fundamental vehicle-modulated crosstalk among various cells in the tumor microenvironment. The systematic understanding of exosomes in gastric cancer (GC) enhances our comprehension about the tumor growth, metastasis, chemoresistance and diagnosis of cancers. The versatile functions of exosomes provide reasonable explanations about the propensity for GC metastasis. The selectively enriched components, especially some exosomal miRNAs, are potential noninvasive biomarkers for sensitive and specific GC diagnosis. Given the c...

This study aimed to quantitatively grasp the structure of support for balancing cancer treatment and work among occupational health nurses (OHNs) with the current implementation status. The anonymous questionnaire was designed based on the findings of our previous qualitative study and distributed to OHNs. The degrees of support implementation for workers with cancer, superiors and colleagues, and human resource managers were assessed for each item. Factor analysis of support items was conducted, and Wilcoxon signed-rank test was carried out to compare the support scores between the factors. Support for workers with cancer...

Publication date: Available online 19 February 2020Source: Mechanisms of Ageing and DevelopmentAuthor(s): Cui Chen, Min Zhou, Yuchen Ge, Xiaobo WangAbstractAging is a biological phenomenon in which the structure and function of organisms declining with the increasing of age. It has become a major risk factor of human diseases, including diabetes, cancers, cardiovascular diseases and neurodegenerative diseases. Silencing information regulator 2 related enzyme 1(sirtuin1, SIRT1) is an NAD+-dependent deacetylase, which has been reported to be involved in the regulation of cellular senescence and aging. The expression of SIRT1...

AbstractBackgroundThe proportion of elderly patients undergoing surgery for gastric cancer is increasing. However, limited number of therapeutic outcomes in the elderly has been reported. Here we examined the surgical results based on a nationwide survey of elderly patients who underwent surgery for Stage I gastric cancer.MethodsData from 68,353 Stage I patients who underwent gastrectomy between 2001 and 2007 were retrospectively collected. The accumulated data were reviewed and analyzed by the Japanese Gastric Cancer Association registration committee. We first classified the patients as those aged  ≤ 74&...

AbstractBackgroundLong non-coding RNAs (lncRNAs) have emerged as important roles in gastric cancer (GC). However, the role of the dysregulated lncRNAs in GC remained large unknown. We investigated the clinical significance, biological function and mechanism of CTC-497E21.4 in GC.MethodsFirstly, RTFQ-PCR was used to detect the expression of CTC-497E21.4 in GC. Furthermore, knockdown of CTC-497E21.4 was conducted to assess the effect of CTC-497E21.4 in vitro and vivo. Subcellular localization of CTC-497E21.4 was determined by nuclear plasmolysis PCR and FISH. We also predicted CTC-497E21.4 binding miRNAs and downstream targe...

AbstractThe biliary tract cancer (BTC) covers a range of carcinomas, including intrahepatic cholangiocarcinoma (ICC), cholangiolocellular carcinoma (CoCC), perihilar cholangiocarcinoma (perihilar CC), extrahepatic cholangiocarcinoma (ECC), and gallbladder cancer (GBC), defined according to the anatomical location. These adenocarcinomas mostly comprise biliary epithelial cell-derived malignant cells. In addition to anatomical differences, there are morphological and biological differences in BTC starting from embryonic development of the tissues extending to physiological differences. Fatty acid-binding proteins (FABPs) are...

Here, we successfully established organoid lines derived from intrahepatic cholangiocarcinoma, gallbladder cancer, and neuroendocrine carcinoma of the ampulla of Vater. These organoids derived from BTCs were cultured stably for>1 year and...

Abstract Human epidermal growth factor receptor 2 (HER2) amplification/overexpression is an effective therapeutic target in breast and gastric cancer. Although HER2 positivity has been reported in other malignancies, previous studies generally focused on one cancer type, making it challenging to compare HER2 positivity across studies/malignancies. Herein, we examined 37,992 patient samples for HER2 expression (+/− amplification) in a single laboratory. All 37,992 patients were tested by immunohistochemistry (IHC); 21,642 of them were also examined for HER2 amplification with either fluorescent in situ hybrid...
