LITERATURE
immunofluorescence analysis of bovine oocytes and preimplantation embryos revealed the consistent expression of MAT2A (the catalytic subunit of the ubiquitously expressed-type of MAT isozyme) during this period
-
increased transcription level in cold treatment
MAT1A expression falls in hepatocytes and bile duct epithelial cells during chronic cholestasis and in human cholangiocarcinoma
MAT1A expression falls in hepatocytes and bile duct epithelial cells during chronic cholestasis and in murine cholangiocarcinoma
S-adenosylmethionine synthase is one of the genes highly expressed under salt stress. Expression increases to 4.5fold after 2 h and to 5.8fold after 24 h of salt stress
-
the enzyme expression in leaves is greatly induced by cold, abscisic acid, H2O2 and nitric oxide
the enzyme is inhibited by peroxides contaminating parenteral nutrition
-
transcripts for the isoform metK1-sp are induced as Streptomyces cells enter the decline phase
transcripts for the isoform metK1-sp are repressed as Streptomyces cells enter the decline phase
