Knockdown OGT inhibits proliferation and tumorsphere formation of hepatoma cell through reducing eIF4E expression. A, Huh7 and PLC/PRF/5 cells were infected with control shRNA, OGT shRNA2 alone, or with wild‐type eIF4E lentivirus. The cell lysates were harvested for western blotting analysis using indicated antibodies. beta ‐actin expression was served as a loading control. B, Cell proliferation of Huh7 and PLC/PRF/5 cells infected with lentiviruses as in panel (A) were measured with CCK8 assay. (C‐H) Huh7 and PLC/PRF/5 cells infected with lentiviruses as in panel (A) were seeded into 96‐well plates. After 12 d, tumorsphere were counted and quantified. Representative images of sphere (scale bars, 100 μm) were shown (C, F). The diameter of sphere (D, G) and number of sphere (E, H) were count. Data represent mean ± SD of at least three independent experiments. The two‐tailed Student's t tests were used. **P < 0.01. I, Huh7 cells expressing either OGT shRNA2 alone or with wild‐type eIF4E lentivirus were incubated with PE‐labelled anti‐AC133 antibody. The percentages of CD133+ cells in graphs were analysed by flow cytometry. Black line, control IgG staining; red line, CD133 staining. J, Cell lysates were examined by western blotting with indicated antibodies. The right panel showcases relative protein amounts of different groups. Error bars represent ±SD of triplicate experiments. **P < 0.01; n.s, no significance. K, Huh7 cells were collected and subjected to immunoprecipitation with antibody against eIF4E or normal mouse IgG. Total RNAs were purified from immunocomplexes and subjected to RT‐PCR to measure Sox2, OCT4, and KLF4 mRNAs associated with eIF4E Image collected and cropped by CiteAb from the following publication (https://pubmed.ncbi.nlm.nih.gov/30677218), licensed under a CC-BY license.

Detection of Human Oct-3/4 by Immunocytochemistry/Immunofluorescence

Neural induction of hPSCs. (a) Both hPSC culture and neural differentiation were performed on LN521 substrate. Cortical neurons were induced with dual SMAD inhibition, expanded in the presence of FGF2, and matured with support by a selection of neurotrophic factors. Neural progenitor cells (NPCs) could be cryopreserved at day 21 and plated at day 32 for final experiments, including microelectrode array (MEA) measurements. (b) Three different hPSC lines (one hESC line, 08/023 and two hiPSC lines, 10212.EURCCs and IMR90-4) were characterized for their efficiency in producing neuroectodermal cells in response to 12-day neural induction by dual SMAD inhibition. Cells were stained for pluripotency marker Oct4 at the pluripotent stage and after 12 days of neural induction. The presence of early neuroectodermal markers was evaluated with Sox2, FoxG1 and Pax6 staining. (c) After 21 days of differentiation, the culture contained vimentin- and Pax6-positive NPCs that could be cryopreserved. Additionally, the first Tbr2- and MAP2-positive neurons were detected at this time point. (d) The percentages of Pax6-positive cells were quantified at four time points of differentiation (mean ± s.e.m., n = 5–14, data derived from 1–3 independent differentiations). Statistical analysis was performed with the Mann-Whitney U test to compare differences between day 12 and day 46 within each hPSC line, and significant p-values are presented in the image. The scale bar is 50 µm in all images. Image collected and cropped by CiteAb from the following publication (https://pubmed.ncbi.nlm.nih.gov/31748598), licensed under a CC-BY license.

Background: Oct-3/4

Oct-3/4, a member of POU transcription factors, was identified as a DNA-binding protein that activates gene transcription via a cis-element containing an octamer motif (1). It is expressed in totipotent embryonic stem and germ cells (2, 3). A critical amount of Oct-3/4 expressed is required to sustain stem cell self-renewal and pluripotency (4). When embryonic stem cells are induced to differentiate, Oct-3/4 is downregulated and this downregulation of Oct-3/4 has proven to be essential for proper and divergent developmental program (5). The Oct-3/4 molecule is not only a master regulator of pluripotency that controls the lineage commitment but also is the most recognized marker used for the identification of totipotent embryonic stem cells.
