Abstract
The Yes-associated protein (YAP) oncoprotein has been linked to both metastases and resistance to targeted therapy of lung cancer cells. We aimed to investigate the effect of YAP pharmacological inhibition, using YAP/TEA domain (TEAD) transcription factor interaction inhibitors in chemo-resistant lung cancer cells. YAP subcellular localization, as a readout for YAP activation, cell migration, and TEAD transcription factor functional transcriptional activity were investigated in cancer cell lines with up-regulated YAP, with and without YAP/TEAD interaction inhibitors. Parental (A549) and paclitaxel-resistant (A549R) cell transcriptomes were analyzed. The half-maximal inhibitory concentration (IC50) of paclitaxel or trametinib, which are Mitogen-Activated protein kinase and Erk Kinase (MEK) inhibitors, combined with a YAP/TEAD inhibitor (IV#6), was determined. A three-dimensional (3D) microfluidic culture device enabled us to study the effect of IV#6/paclitaxel combination on cancer cells isolated from fresh resected lung cancer samples. YAP activity was significantly higher in paclitaxel-resistant cell lines. The YAP/TEAD inhibitor induced a decreased YAP activity in A549, PC9, and H2052 cells, with reduced YAP nuclear staining. Wound healing assays upon YAP inhibition revealed impaired cell motility of lung cancer A549 and mesothelioma H2052 cells. Combining YAP pharmacological inhibition with trametinib in K-Ras mutated A549 cells recapitulated synthetic lethality, thereby sensitizing these cells to MEK inhibition. The YAP/TEAD inhibitor lowered the IC50 of paclitaxel in A549R cells. Differential transcriptomic analysis of parental and A549R cells revealed an increased YAP/TEAD transcriptomic signature in resistant cells, downregulated upon YAP inhibition. The YAP/TEAD inhibitor restored paclitaxel sensitivity of A549R cells cultured in a 3D microfluidic system, with lung cancer cells from a fresh tumor efficiently killed by YAP/TEAD inhibitor/paclitaxel doublet. Evidence of the YAP/TEAD transcriptional program's role in chemotherapy resistance paves the way for YAP therapeutic targeting.

Abstract
Lysophosphatidic acid (LPA), a prototypical ligand for G protein coupled receptors, and Forkhead box protein M1 (FOXM1), a transcription factor that regulates expression of a wide array of genes involved in cancer initiation and progression, are two important oncogenic signaling molecules in human epithelial ovarian cancers (EOC). We conducted in vitro mechanistic studies using pharmacological inhibitors, genetic forms of the signaling molecules, and RNAi-mediated gene knock-down to uncover the molecular mechanisms of how these two molecules interact in EOC cells. Additionally, in vivo mouse studies were performed to confirm the functional involvement of FOXM1 in EOC tumor formation and progression. We show for the first time that LPA up-regulates expression of active FOXM1 splice variants in a time- and dose-dependent manner in the human EOC cell lines OVCA433, CAOV3, and OVCAR5. Gi-PI3K-AKT and G12/13-Rho-YAP signaling pathways were both involved in the LPA receptor (LPA1-3) mediated up-regulation of FOXM1 at the transcriptional level. In addition, down-regulation of FOXM1 in CAOV3 xenografts significantly reduced tumor and ascites formation, metastasis, and expression of FOXM1 target genes involved in cell proliferation, migration, or invasion. Collectively, our data link the oncolipid LPA, the oncogene YAP, and the central regulator of cell proliferation/mutagenesis FOXM1 in EOC cells. Moreover, these results provide further support for the importance of these pathways as potential therapeutic targets in EOC.

Abstract
PURPOSE To investigate biological impact of the downregulation of yes-associated protein (YAP) through RNA interference in the process of epithelial-mesenchymal transition in MHCC97H and MHCC97L. METHODS MHCC97H and MHCC97L cells were transiently transfected by YAP-siRNA. Furthermore, protein expressions and mRNA levels of characteristic markers of epithelial-mesenchymal transition (E-cadherin, N-cadherin) were examined by Western blotting and real-time polymerase chain reaction, and transwell invasion assay was used to detect changes of invasiveness of MHCC97H and MHCC97L cells. RESULTS The transfected group with YAP-siRNA in MHCC97H after 72 h by Western blotting showed obviously higher expression of E-cadherin compared with the control group (P < 0.05), and lower expression of N-cadherin (P < 0.05). In MHCC97L cells, the expression of E-cadherin was also significantly increased (P < 0.05); however, N-cadherin expression did not significantly change (P > 0.05). Moreover, compared with the control group, Transwell invasion assay showed that the number of the transfected groups was significantly decreased in MHCC97H and MHCC97L cell lines (both P < 0.05). The result of real-time polymerase chain reaction indicated that mRNA levels of E-cadherin increased (P < 0.05), but the mRNA levels of N-cadherin did not significantly change (P > 0.05) in these two cell lines, indicating some effects of post-transcriptional regulation mechanism after silencing YAP. CONCLUSIONS YAP expression in human hepatocellular carcinoma cell lines MHCC97H and MHCC97L is closely related with the characteristic markers of epithelial-mesenchymal transition, N-cadherin and E-cadherin expression.
