The oxidative processes and antioxidative system in cucumber (Cucumis sativus L.) fruit were determined during development and senescence. Four distinct developmental stages could be delineated during fruit maturation: immature (3–8 d after anthesis, DAA), mature (9–16 DAA), breaker (17–22 DAA), and yellow (35–40 DAA). The electrolyte leakage,(More)
Plant microRNAs (miRNAs) play important roles in regulating plant growth, development, and responses to abiotic stresses. In this study, 38 miRNAs (TaMIRs) from wheat (Triticum aestivum L.), 36 from the miRBase database, and two from our previous work were characterized and subjected to an expression pattern analysis under normal conditions and a drought(More)
Here we show that the transcription-repressor DREAM binds to the A20 promoter to repress the expression of A20, the deubiquitinase suppressing inflammatory NF-κB signaling. DREAM-deficient (Dream −/−) mice displayed persistent and unchecked A20 expression in response to endotoxin. DREAM functioned by transcriptionally repressing A20 through binding to(More)
Foxm1, a mammalian Forkhead Box M1 protein, is known as a typical proliferation-associated transcription factor. Here, we find that Foxm1 was essential for maintenance of hematopoietic stem cell (HSC) quiescence and self-renewal capacity in vivo in mice. Reducing expression of FOXM1 also decreased quiescence in human CD34 + HSCs and progenitor cells and its(More)
Lactate dehydrogenase C4 (LDH-C4) is considered to be a good target protein for the development of contraceptive drugs. To develop contraceptive rodenticide against pika (Ochotona curzoniae) LDH-C4, the pika LDH-C gene was cloned and expressed in Escherichia coli. The recombinant protein was purified and characterized. The cDNA of pika LDH-C gene was cloned(More)
