This study was undertaken to elucidate the effect of diallyl disulfide from Allium sativum, an oil-soluble organosulfur compound found in garlic, in suppressing human non-small cell lung carcinoma H1299 cells. A potent increase in apoptotic cells has accompanied 1) a decrease in cell viability, 2) an increase of the fraction of G2/M-phase cells by up to(More)
p38 mitogen-activated protein kinase (MAPK) is of fundamental importance in a cell's response to environmental stresses, cytokines and DNA damage. p38 resides in the cytoplasm of resting cells, and translocates into the nucleus upon activation, yet the exact mechanisms remain largely unclear. We show here that the phosphorylation-dependent nuclear(More)
Activation of the stem cell transcriptional circuitry is an important event in cancer development. Although cancer cells demonstrate a stem cell-like gene expression signature, the epigenetic regulation of pluripotency-associated genes in cancers remains poorly understood. In this study, we characterized the epigenetic regulation of the(More)
Cancer was hypothesized to be driven by cancer stem cells (CSCs), but the metabolic determinants of CSC-like phenotype still remain elusive. Here, we present that hexosamine biosynthetic pathway (HBP) at least in part rescues cancer cell fate with inactivation of glycolysis. Firstly, metabolomic analysis profiled cellular metabolome in CSCs of(More)
p53 plays a fundamental role in the maintenance of genome integrity after DNA damage, deciding whether cells repair and live, or die. However, the rules that govern its choice are largely undiscovered. Here we show that the functional relationship between p38 and p53 is crucial in defining the cell fate after DNA damage. Upon low dose ultraviolet (UV)(More)
UNLABELLED Liver transplantation (LT) is a cure for many liver diseases. Blood chimerism of donor origin can develop after LT, which raises the possibility of the existence of hematopoietic stem/progenitor cells (HSPCs) in the liver. We characterized the blood chimerism in a large cohort of 249 LT patients and analyzed putative HSPCs in adult human livers.(More)
Previous studies have suggested that short-term exposure to ambient air pollution was associated with pediatric hospital admissions and emergency room visits for certain respiratory diseases; however, there is limited evidence on the association between short-term air pollution exposure and pediatric outpatient visits. Our aim was to quantitatively assess(More)
The DNA damage-mediated cell cycle checkpoint is an essential mechanism in the DNA damage response (DDR). During embryonic development, the characteristics of cell cycle and DNA damage checkpoint evolve from an extremely short G1 cell phase and lacking G1 checkpoint to lengthening G1 phase and the establishment of the G1 checkpoint. However, the regulatory(More)
