    Article Snippet: Glycosylated human proBDNF without C-terminal Myc-FLAG tags produced in HEK293F cells and nonglycosylated human proBDNF produced in E. coli (Alomone Labs, number B-257) were used to study the kinetic of cleavage by furin (R&D Systems, number 1503-SE-010).

    Techniques: Stable Transfection

    Extracted ion chromatograms (XIC) of (A) nonglycosylated, NYLDAANMSMR and (B) deglycosylated, NYLDAADMSMR glycopeptide of proBDNF secreted by HEK293F cells confirm site occupancy higher than 99%. C, tandem mass spectrum verifies deglycosylation of the proBDNF peptide under [18O]water.

    Techniques:

    Expression of wildtype (WT) proBDNF and its N121Q mutant (NQ) in stably transfected HEK293F cells. Protein expression was determined by Western blotting using an antibody, recognizing both BDNF and proBDNF, in the conditioned media (A) and cell lysates (B). Arrows point to (pro)BDNF forms: glycosylated proBDNF (black arrow), nonglycosylated proBDNF (white arrow), and mature BDNF (gray arrow). M indicates MagicMark molecular weight marker. Expression of mRNA was determined in WT and N121Q mutant by RT-PCR (C). ProBDNF/BDNF expression in cell lysates (D) or conditioned media (E) of HEK293F cells expressing N121Q mutant treated with proteasome inhibitor MG132 (MG), lysosomal inhibitor chloroquine (CQ), or chemical chaperone 4-phenylbutyric acid (PBA). The black arrow points to the position of nonglycosylated proBDNF.

    Kinetics of cleavage of glycosylated and nonglycosylated proBDNF by furin. Mass difference between glycosylated and nonglycosylated proBDNF enabled densitometric quantification of each proBDNF form: A, representative blot of the cleavage kinetic at the indicated time intervals; B, densitometric analysis of proBDNF intensities at the indicated time intervals. Results are expressed as percent of the proBDNF concentration (mean ± S.D., n = 3) at the beginning of the reaction. Note that proBDNF without C-terminal Myc-FLAG tag was used in the reaction as described under “Experimental procedures.”
