Figure Lengend Snippet: Figure 3. Experimental manipulation of Sox2 and Oct4 in SupM2 SORE6 clones. (A) FACS analysis showing the effect on SORE6 reporter activity of overexpressing Sox2 in single-cell clone 5-4 (SupM2 SORE6−). (B) FACS analysis showing the effect on SORE6 reporter activity of overexpressing shSox2 in single-cell clone 6-5 (SupM2 SORE6+). (C) FACS analysis showing the effect of Oct4 downregulation on SORE6 reporter activity in clone 5-4 (SupM2 SORE6−). (D) FACS analysis showing the effect of shOct4 transfection on SORE6 reporter activity in single-cell clone 6-5 (SupM2 SORE6+). All results shown are representative of three independent experiments and were also repeated in a second batch of single-cell clones. Side panels show the fold change of GFP in log scale (mean ± SEM). Bottom panels of each figure are the Western blots showing the effect of transient transfection with Sox2, Oct4, shSox2, and shOct4 plasmids. Empty vector (EV) was included as a negative control. ** p < 0.01, *** p < 0.001.

Article Snippet: The Oct4 expression vector (pLVEF1a-hOCT4-IRES-Neo) was purchased from BiOSETTIA (San Diego, CA, USA). shRNA for Sox2 (#26353) and the Sox2 expression vector (#16577) were purchased from Addgene (Watertown, MA, USA).

(A) The subcellular localization of Sox2, Oct4, and c-Myc in SORE6−and SORE6+ cells derived from SupM2, assessed by the nuclear cytoplasmic fractionation assay. (B) The DNA pull-down assay was performed to assess Sox2, Oct4, and c-Myc transcriptional activity in SORE6−and SORE6+ cells using a biotin-labeled SORE6 probe.

Article Title: Basal cells of the human airways acquire mesenchymal traits in idiopathic pulmonary fibrosis and in culture.

doi: 10.1038/labinvest.2015.114

Figure Lengend Snippet: Figure 1 Basal cell reactivity, hyperplasia and upregulation of EMT markers adjacent to fibroblastic foci. Epithelium adjacent to fibroblastic foci shows increased reactivity and mesenchymal phenotype. Sparse staining of CK14 is seen in control samples, whereas CK14 is strongly expressed in epithelium overlying fibroblastic foci. P63, a restricted transcription factor for basal cells is expressed in epithelial cells located both basally and in the top layer indicating formation of metaplasia in IPF samples. E-cadherin is abundant in epithelium both in control and IPF samples. In addition, E-cadherin is present in cells within the foci. N-cadherin is expressed in lower basal epithelial cells in IPF samples whereas control samples are negative. Vimentin is expressed in both epithelium and mesenchyme in IPF samples. Bar 100 μm.

Article Snippet: Lentiviral transduction was performed as previously described.28 In short, plasmids containing scrambled hairpin (pLKO.1 shSCR; Addgene plasmid 17920)29 or shRNA against p63 (shp63alpha pLKO.1 puro; Addgene plasmid 19120)30 were used with packaging plasmids (psPAX2 and pMD2.G) (Addgene plasmids 12260 and 12259, respectively) to generate viral titer in HEK-293 T cells using Arrest-in (Open Biosystems).

Figure Lengend Snippet: Figure 5 Knockdown (KD) of p63 abrogates UG-induced EMT of VA10 cells. p63 KD cells are unable to undergo UG-induced EMT. The expression of the mesenchymal markers N-cadherin and Thy-1 is abrogated in treated KD cells, whereas scrambled control cells show a division into two cellular sub-populations much like the mother cell line VA10. The expression of Vimentin can still be detected in treated KD cells, although to a lesser extent than in treated scrambled cells. Bars 100 μm.
