The aim of the current study was to investigate the correlation of cancer-associated fibroblasts (CAFs) with the migration and invasion abilities of gastric cancer cells. Gastric CAFs were grown in primary cultures. The in vitro model of interaction of SGC7901 gastric cancer cells with gastric CAFs was established by the use of Transwell co-culture cells to(More)
Ductal carcinoma in situ (DCIS) is the most common type of non-invasive breast cancer. The currently accepted step-wise model suggests that breast cancer progressed in the following manner: normal breast cell→usually ductal hyperplasia (UDH)→atypical ductal hyperplasia (ADH)→DCIS→invasive ductal carcinoma (IDC). Therefore, DCIS can serve as a good model to(More)
There is an unmet clinical need to identify biomarkers for breast cancer neoadjuvant chemotherapy. Here, using miRNA TaqMan Low-Density Arrays (TLDA), we analyzed the miRNA expression profile in pre-treatment needle aspiration tumor samples from patients who received taxane-anthracycline-based neoadjuvant chemotherapy. Although, in an unsupervised(More)
Invasive micropapillary carcinoma (IMPC) is an uncommon histological type of breast cancer. IMPC has a special growth pattern and a more aggressive behavior than invasive ductal carcinomas of no special types (IDC-NSTs). microRNAs are a large class of non-coding RNAs involved in the regulation of various biological processes. Here, we analyzed the small RNA(More)
St. Gallen 2005 expert consensus guideline modified its criteria for the risk category of breast cancer (BC) patients by integrating a combination of lymph nodes with metastasis (positive lymph nodes [PLNs]) and HER-2/neu status of tumor. Recently, some studies have shown that lymph node ratio (LNR), defined as the ratio of axillary lymph nodes with tumor(More)
BACKGROUND Pattern recognition receptor nucleotide-binding oligomerization domain 2 (NOD2) is well investigated in immunity, but its expression and function in platelets has never been explored. METHOD AND RESULTS Using reverse transcription polymerase chain reaction and Western blot, we show that both human and mouse platelets express NOD2, and its(More)
Skeletal muscle stem cells, called satellite cells, are a quiescent heterogeneous population. Their heterogeneity is influenced by Pax7, a well-defined transcriptional regulator of satellite cell functions that defines two subpopulations: Pax7(Hi) and Pax7(Lo). However, the mechanisms by which these subpopulations are established and maintained during(More)
Within the past several years, inhibition of the PARP1 activity has been emerged as one of the most exciting and promising strategies for triple-negative breast cancer (TNBC) therapy. The purpose of this study is to assess PARP1 expression in TNBCs and to evaluate the association between polymorphisms in PARP1 promoter or 3' untranslated region (3'UTR) and(More)
Obesity has been linked to many health problems, such as diabetes. However, there is no drug that effectively treats obesity. Here, we reveal that miR-378 transgenic mice display reduced fat mass, enhanced lipolysis, and increased energy expenditure. Notably, administering AgomiR-378 prevents and ameliorates obesity in mice. We also found that the energy(More)
