Arabidopsis belongs to the Brassicaceae family and plays an important role as a model plant for which researchers have developed fine-tuned genome resources. Genome sequencing projects have been initiated for other members of the Brassicaceae family. Among these projects, research on Chinese cabbage (Brassica rapa subsp. pekinensis) started early because of(More)
Aplysiatoxin and debromoaplysiatoxin, a debrominated form of aplysiatoxin, have both been shown to be potent tumor promoters in a two-stage carcinogenesis experiment on mouse skin. However, debromoaplysiatoxin did not behave like aplysiatoxin in most of the biological assay systems using cultured cells. The discrepancy was supposed to be due to a factor in(More)
Mouse sarcoma 180 cells have a polypeptide that has the same molecular weight as actin but it is more acidic than alpha-actin. Its tryptic peptide pattern on reversed-phase HPLC was very similar to that of beta + gamma-actin, an actin sample prepared by affinity chromatography on DNase I-Sepharose contained the acidic polypeptide, and monoclonal anti-actin(More)
The changes of protein kinases (PKs) in the nuclear matrix of HL-60 cells during the differentiation by retinoic acid (RA) were examined by in situ assay after sodium dodecyl sulfate-polyacrylamide gel electrophoresis. In the nuclear matrix of HL-60, at least seven species of PKs (83, 63, 58, 46, 42, 38, and 31 kDa) were always detected. Among these PKs, 63(More)
