In the presence of NGF, PC12 cells extend neuronal processes, cease cell division, become electrically excitable, and undergo several biochemical changes that are detectable in developing sympathetic neurons. We investigated the expression pattern of the apoptosis-related genes at each stage of neuronal differentiation using a cDNA microarray containing 320 apoptosis-related rat genes. By compa...

Heat stress can cause immune organ dysfunction and apoptosis. Polysaccharide of Atractylodes macrocephala Koidz may have protective effects on immune organs. In this study, we established chicken models of Polysaccharide of Atractylodes macrocephala Koidz-heat stress interaction and detected the oxidative index, activities of mitochondrial complexes and ATPases as well as the ultrastructure in ...

The death receptor and endoplasmic reticulum (ER) are closely related to cell apoptosis, and it is worth studying whether the apoptosis pathways mediated by them are involved in liver regeneration. To understand the mechanism underlying death receptor- and ER-mediated apoptosis during rat liver regeneration, we used the Rat Genome 230 2.0 Array to determine the changes in gene expression. We th...

Insulin producing β-cells are exposed to hypoxic stress in the early period after islet transplantation. Although it has been suggested that hypoxia leads to islet loss, the underlying mechanisms are unclear. In this study, the early transcriptional profiles of b cell response to hypoxia were determined by using the Affymetrix Murine Genome Array U74Av2 GeneChip (about 12,422 genes). In additio...

We applied oligomicroarray analysis of 17086 genes to identify the genes related to lymph node metastasis in esophageal squamous cell carcinoma (ESCC). The samples of cancer and non-cancerous paired tissue were taken from 16 patients with ESCC who underwent esophagectomy with lymph node dissection. Total ribonucleic acid was extracted from the cancer cells obtained by using laser microdissectio...
