Hyperosmotic stress‐induced redistribution of pre‐mRNA cleavage factor I subunits is associated with shifts in alternative polyadenylation

FEBS Open Bio, EarlyView.
Hyperosmotic stress triggers the relocation of the CFIm complex from the nucleus to the cytoplasm. This shift creates a nuclear ‘stoichiometric bottleneck’, limiting CFIm availability for mRNA processing. Consequently, specific mRNAs like NUDT21 and DICER1 undergo targeted 3′UTR shortening, demonstrating how spatial protein dynamics drive rapid ...

TRACE ELEMENTS AND BIOLOGICALLY ACTIVE COMPOUNDS OF PULMONARIA MOLLIS AND PULMONARIA OBSCURA

chemistry of plant raw material
The genus Pulmonaria plants are ephemeroids having characteristic distile reproduction system and so should be distinguished – generative shoot with flowers and vegetative rosette leaves as organs these plants. Phytomedicines made from them have different pharmacological action.
