Triple Inhibition of TGFb/BMP/GSK3 Signaling in Human Pluripotent Stem Cells Generates PAX6- Neural Progenitors with robust Self-renewal

ABSTRACT: In this report, we show that in addition to dual SMAD inhibition, blocking Glycogen synthase kinase 3(GSK3) signaling by adding CHIR99021 generated novel NPCs with significantly enhanced proliferation. By RNA-seq, we show that S/D/C NPCs and S/D NPCs display distinct expression profiles, as S/D/C triggered NPCs are Pax6- and express hindbrain genes while . S/D triggered NPCs are Pax6+ and highly express forebrain genes. Our data reveal that Pax6 labels distinct regionally specified hNPCs and manipulating GSK3 signaling could pattern hNPCs with positionally specified fate and different self-renewal capability.

Regulatory phosphorylation of eIF6 by GSK3

Project description:The overall goal of this project is to determine the key sites in the C-terminus of eIF6 that are recognized and phosphorylated by GSK3. Analysis of kinase reactions using the site-specific mutants as well as the C-terminus deletion mutants of eIF6 indicated that there are GSK3-specific motifs in the C-terminus that are phosphorylated by GSK3. The purpose of the Mass Spectrometry studies is to use MS as a targeted and secondary approach to validate and identify GSK3-specific sites of phosphorylation in the C-terminus of eIF6.

Polyubiquitination analysis upon GSK3 inhibition in HeLa cell extracts

Project description:HeLa cell extracts with or without GSK3 enzyme inhibition were assayed using protein microarrays in order to detect GSK3-dependent changes in protein polyubiquitination. HeLa lysates in triplicates were supplemented with ubiquitin and incubated on protein microarrays (ProtoArray 5.0; Invitrogen) in the presence or absence of the GSK3 inhibitor SB-216763. Polyubiquitination of the arrayed proteins was detected using specific antibodies. ProtoArray 5.0 contains over 9,000 full-length human proteins purified and arrayed in duplicate under native conditions to maximize functionality.

Human cortical organoids. Chronic treatment with GSK3 inhibitor CHIR99021. Bulk RNAseq.

Project description:Here we used human cortical brain organoids to probe the longitudinal impact of GSK3 inhibition through multiple developmental stages. Chronic GSK3 inhibition increased the proliferation of neural progenitors and caused massive derangement of cortical tissue architecture. Cortical organoids were differentiated as previously described (Paşca et al., 2015, doi: 10.1038/nmeth.3415.).Chronic GSK3 inhibition was performed by adding CHIR99021 (Merck SML1046) to the medium at day 0 (1 microM) and kept throughout the differentiation process until reaching the respective collection timepoints (day 18, day 50, day 100).
