    Figure Lengend Snippet: CDX2 acts as a transcriptional repressor of UPK1B and its high expression is associated with favorable prognosis of patients with GC. (A) Venn diagram showing overlapping predicted transcriptional regulators of UPK1B from ChEA and ChEA3 databases. (B) Knockdown of CDX2 in AGS cells resulted in increased UPK1B (C) mRNA and (D) protein expression. (E) Overexpression of CDX2 in MKN45 cells reduced UPK1B protein levels. Data from (F) The Cancer Genome Atlas Stomach Adenocarcinoma cohort and (G) the Kaplan-Meier plotter database indicated that high CDX2 expression was associated with improved prognosis of patients with GC. UPK1B, uroplakin 1B; GC, gastric cancer; si, small interfering RNA; NC, negative control; OE, overexpression; HR, hazard ratio; CDX2, caudal-related homeobox transcription factor 2; ChEA, ChIP-X Enrichment Analysis.

    Article Snippet: Cells were also transfected with small interfering RNAs (siRNAs) targeting CDX2 or PIK3IP1 , with a universal non-targeting scrambled siRNA (si-NC) as the negative control , obtained from GeneChem, Inc. For UPK1B and CDX2 overexpression, the p-TSB-CMV-UPK1B and p-TSB-CMV-CDX2 expression vectors [Shanghai Genomeditech Co., Ltd.] and the corresponding empty p-TSB-CMV vector (negative control) were used.

    UPK1B activates PI3K/AKT signaling by antagonizing the inhibitory regulator PIK3IP1 in gastric cancer cells. (A) Venn diagram showing that PIK3IP1 was identified as a putative UPK1B-interacting partner based on BioGRID and HIPPIE protein-protein interaction databases. (B) UPK1B and PIK3IP1 co-localized in the cytoplasm and plasma membrane of MKN45 cells. (C) Interaction between UPK1B and PIK3IP1 in MKN45 cells. (D) Knockdown of PIK3IP1 in MKN45 cells. (E) Silencing PIK3IP1 in UPK1B-knockdown MKN45 cells restored PI3K/AKT pathway activation. Knockdown of PIK3IP1 reversed the decrease in (F) migration/invasion and (G) wound-healing capacity in UPK1B-silenced MKN45 cells. UPK1B, uroplakin 1B; p-, phosphorylated; si, small interfering RNA; sh, short hairpin RNA; NC, negative control; PIK3IP1, PI3K inhibitor interacting protein 1; HIPPIE, Human Integrated Protein-Protein Interaction Reference; IP, immunoprecipitation.

    TCF7 regulates pro−caspase−8 expression in T lymphocytes and is significantly reduced in COPD. ( A ) Immunofluorescence co−staining of control human lung tissue displaying separate channels for DAPI (blue), caspase−8 (green), TCF7 (red), and the merged image. Scale bar is 50 μm. ( B ) Immunofluorescence co−staining of COPD human lung tissue displaying separate channels for DAPI (blue), caspase−8 (green), TCF7 (red), and the merged image. Note the marked reduction in both TCF7 and caspase−8 signals compared to the control. Scale bar is 50 μm.
