Effects of microRNA-708 on Epithelial-Mesenchymal Transition, Cell Proliferation and Apoptosis in Melanoma Cells by Targeting LEF1 through the Wnt Signaling Pathway.
This study was conducted in order to elucidate the role microRNA-708 (miR-708) plays between proliferation, invasion, migration, and epithelial-mesenchymal transition (EMT) involving melanoma cells by targeting using LEF1 through the Wnt signaling pathway. Male Kunming mice were selected and subsequently divided into normal and model groups to take part in this study. Following cell line selection, the B16 cells with the highest miR-708 expression were selected and assigned into the control, blank, negative control (NC), miR-708 mimic, miR-708 inhibitor, siRNA-LEF1, and miR-708 inhibitor + siRNA-LEF1 groups. A Bioinformati...

NOD2 and TLR2 Signal via TBK1 and PI31 to Direct Cross-Presentation and CD8 T Cell Responses
The objective of this study was to explore the role of NOD2 and TLR2 in cross-presentation in human dendritic cells undertaking an unbiased screen. We have used a quantitative phosphoproteomic analysis by liquid chromatography-tandem mass spectrometry (LC-MS/MS) followed by a computational analysis to identify the proteins as differentially abundant in response to NOD2 and TLR2 sensing. Validation of the phosphoproteomic analysis was performed by the detection of proteins in phosphoenriched lysates and detected by western blot. Techniques for the modulation of gene expression (shRNA and siRNA) were used to confirm the resu...

Detailed Dissection of UBE3A-Mediated DDI1 Ubiquitination
Discussion
Poly-ubiquitinated proteins targeted for degradation might be recognized directly by proteasomal receptors or by proteasomal shuttling proteins. The first shuttling proteins – Ddi1, Rad23 and Dsk2 – were identified and characterized in Saccharomyces cerevisiae (Lambertson et al., 1999; Kaplun et al., 2005). Proteasomal shuttles contain an N-terminal ubiquitin-like (UBL) domain that interacts with the 26S proteasome (Finley, 2009), and a C-terminal ubiquitin-binding domain domain (UBD) that binds to ubiquitin or poly-ubiquitin chains (Bertolaet et al., 2001). When ubiquitinated, substrates are capt...

Effect of Programmed Death-Ligand 1 in Cancer-Associated Fibroblasts on Advanced Laryngeal Squamous Cell Carcinoma
This study aimed to explore the effect of programmed death-ligand 1 (PD-L1) in cancer-associated fibroblasts (CAFs) on advanced laryngeal squamous cell carcinoma (LSCC). The expression of PD-L1 in advanced LSCC tumor tissues was observed in 83 patients with LSCC by immunofluorescence microscopy and compared with that in normal laryngeal mucosa. The CAFs of LSCC and normal fibroblasts (NFs) were isolated, cultured, purified, and examined by fluorescence. The expression of PD-L1 in purified CAFs and NFs was measured by flow cytometry. The expression of PD-L1 in CAFs was downregulated through small interferring RNA (siRNA) tr...

Knockdown of DEAD-box 51 inhibits tumor growth of esophageal squamous cell carcinoma < em > via < /em > the PI3K/AKT pathway
CONCLUSION: Our study suggests for the first time that DDX51 promotes cancer cell proliferation by regulating the PI3K/AKT pathway; thus, DDX51 might be a therapeutic target for ESCC.PMID:35125830 | PMC:PMC8790558 | DOI:10.3748/wjg.v28.i4.464
