Gastric cancer (GC) is one of the most common cancer worldwide. Specific and reliable molecular markers are limited; it is critical to identify new biomarkers for GC to aid in early diagnosis, treatment strategy, and prognosis evaluation. Microarray technology makes it possible to measure the expression levels of thousands of genes, and identifying meaningful and useful molecular targets from these large data.
Downregulation of ALDOB is associated with poor prognosis of patients with gastric cancer.

View SamplesThe alkylating agent N-methyl-N'-nitro-N-nitrosoguanidine (MNNG) is a direct mutagen and carcinogen, causing DNA damage and other comprehensive alterations that lead to chromosomal aberrations, mutations, tumor initiation, and cell death. Our previous study revealed that MNNG at different concentrations could induce extensive changes in gene expression at an early stage of exposure. To further understand the dynamic cellular responses and hazardous effects caused by this environmental carcinogen, we used a whole-genome time-course screening methods to find out the gene expression changes induced by a low concentration of MNNG in human normal amnion epithelial FL cells. The cells were exposed to 1.0 M MNNG, and differential gene expression profiles at 3, 12, and 24 h after MNNG treatment were obtained by use of Affymetrix HG-U133 Plus 2.0 oligonucleotide microarray technology, followed by quantitative real-time RT-PCR validation. The results showed that the low-dose MNNG exposure triggered extensive but moderate changes in gene expression at these three experiment time points after exposure. The responsive genes encode important proteins, including cell cycle regulators, transcription factors and signal transducers that determine cell cycle progression, cell fate and other activities associate with pro-oncogenic potentials. The differential gene expression profiles at the three time points varied greatly, and generally reflected a cellular responsive process from initiation to progression and to recovery after MNNG exposure. These results will aid our understanding of the complicated mechanisms of MNNG-induced cellular responses.

View SamplesXuesaitong injection (XST), a standardized patent Chinese medicine of Panax notoginseng roots (Sanqi in Chinese), has long been used for effective prevention and treatment of stroke in China. However, the mechanisms underlying its effects against ischemic stroke are still poorly understood. In this study, we focused on the polypharmacology of XST against ischemic stroke with a XST-regulated stroke network analysis.

View SamplesRecent advances highlight the power of small molecules for promoting cellular reprogramming. Yet, the full potential of such chemicals in cell fate manipulation and the underlying mechanisms needs further characterization. Through functional screening assays, we found that mouse embryonic fibroblast can be induced to trans-differentiate into a wide range of somatic lineages simultaneously by treatment with a combination of four chemicals. Genomic analysis of the process indicates activation of multi-lineage modules and relaxation of epigenetic silencing programs. In addition, we identify Sox2 as an important regulator within the induced network. Single cell analysis uncovers a priming state that enables transition from fibroblast cells to diverse somatic lineages. Finally, we demonstrate that modification of the culture system enables directional trans-differentiation towards cardiac, neuronal or adipocytic lineages. Our study describes a cell fate control system that may be harnessed for regenerative medicine.
