B12-retro-riboswitches: guanosyl-induced constitutional switching of B12 coenzymes.
Complete B12 derivatives are natural "molecular switches" as a result of the coordinative switch ("base on" or "base off") of the natural nucleotide base. Certain predesigned B12-nucleotide conjugates were shown recently to behave as "retro riboswitches", in which the nucleotide environment modified the equilibrium between these two isomeric B12 structures. In contrast, the "reverse" situation ...
متن کاملاثر ویتامین B12 در مدل هیپرگلیسمی حاد ناشی از تزریق کتامین-گزیلازین در موش صحرایی
Background & Aims: Sympathetic nervous system thorough α-2 adrenoceptors and insulin have principal roles in blood glucose regulation. On the other hand, vitamin B12 participates in sympathetic system and insulin functions. In this study, the effect of vitamin B12 on acute hyperglycemia induced by ketamine-xylazine was investigated. In order to clarify the possible mechanism of the e...

Background and purpose: Myelin-producing oligodendrocytes play a key role in supporting normal neuronal function of the mammalian central nervous system (CNS). Formation of myelinating oligodendrocytes from their precursors requires activation and coordination of a set of stage-specific transcriptional regulators that are important for the biosynthesis of myelin components. Olig2 plays an impor...
