(Submitter supplied) Deficiency of deacetylase SIRT1 or its downstream target PRRX1 promotes breast cancer stemness and metastasis. To explore the mechnisms of SIRT1 and its downstream target PRRX1 in breast cancer, we analysed the gene expressions in breast cancer BT549 cells with SIRT1 knockout or PRRX1 knockout or not.

(Submitter supplied) The transcription factor nuclear factor-κB (NF-κB) has important roles for tumorigenesis, but how it regulates cancer stem cells (CSCs) remains largely unclear. We identified insulin-like growth factor 2 (IGF2) is a key target of NF-κB activated by HER2/HER3 signaling to form tumor spheres in breast cancer cells. The IGF2 receptor, IGF1 R, was expressed at high levels in CSC-enriched populations in primary breast cancer cells. more...

(Submitter supplied) To understand the role of the epithelial-to-mesenchymal transition (EMT) and its reverse MET dynamics between health and disease, the identification of epithelial (E)- and mesenchymal (M)-specific genes is essential. The aim of the study was to derive genes that are characteristic E and M phenotypes in breast-derived cells. Their identification can help to understand the functional meaning of their expression and dynamic changes of individual cells, whole cell populations, and tumors, and even patients. more...

(Submitter supplied) Cancer stem cell (CSC) identification relies on transplantation assays of cell sub-populations sorted from fresh tumor samples. Herein, we attempt to bypass limitations of abundant tumor source and predetermined immune selection by in-vivo propagating patient derived xenografts (PDX) from human malignant rhabdoid tumor (MRT), a rare and lethal pediatric neoplasm, to an advanced state in which most cells behave as CSCs. more...

(Submitter supplied) Pancreatic cancer is a common malignant tumor with poor prognosis. Accumulating evidence indicates that sirtuin 1 (SIRT1) exerts biological functions in various cancers.SIRT1 plays an important role in tumorigenesis, development, and drug resistance by blocking aging and apoptosis, also promoting cell growth and angiogenesis.However, how SIRT1 functions in the development of pancreatic cancer stem cells (CSCs) is currently poorly understood. more...

(Submitter supplied) To investigate functional associations between SIRT1 and CUL4B, we used ChIP-seq to analyze genome-wide SIRT1/CUL4B complex transcriptional targets. ChIP experiments were performed first in PANC-1 cells using antibodies against SIRT1 or CUL4B. Next, SIRT1- or CUL4B-associated DNA was amplified using non-biased conditions, labeled, and sequenced. Using Illumina HiSeq2000, we found lots of SIRT1- and CUL4B-specific binding peaks, respectively, representing the ChIP-seq peak. more...

(Submitter supplied) It is still unclear that how obesity increases the risk of breast cancer. To address this question, we used mRNA microarrays to characterize mouse breast tumor EO771 cells treated with mouse recombinant A-FABP protein and compared the data from their controls.
