AbstractLoss of apical-basal polarity and downregulation of cell-cell contacts is a critical step during the pathogenesis of cancer. Both processes are regulated by the scaffolding protein Pals1, however, it is unclear whether the expression of Pals1 is affected in cancer cells and whether Pals1 is implicated in the pathogenesis of the disease.Using mRNA expression data and immunostainings of cancer specimen, we show that Pals1 is frequently downregulated in colorectal cancer, correlating with poorer survival of patients. We further found that Pals1 prevents cancer cell metastasis by controlling Rac1-dependent cell migration through inhibition of Arf6, which is independent of the canonical binding partners of Pals1. Loss of Pals1 in colorectal cancer cells results in increased Arf6 and Rac1 activity, enhanced cell migration and invasion in vitro and increased metastasis of transplanted tumor cells in mice. Thus, our data reveal a new function of Pals1 as a key inhibitor of cell migration and metastasis of colorectal cancer cells. Notably, this new function is independent of the known role of Pals1 in tight junction formation and apical-basal polarity.

Accumulating evidence suggested that calcium release-activated calcium modulator 1(ORAI1), a key calcium channel pore-forming protein-mediated store-operated Ca2+ entry (SOCE), is associated with human cancer. However, its role in colorectal cancer (CRC) progression has not been well studied. Epithelial-mesenchymal transition (EMT) is a multistep process that occurs during the progression of cancers and is necessary for metastasis of epithelial cancer. Transforming growth factor-β (TGF-β) is a pleiotropic cytokine that has been shown to induce EMT. In this study, we are aimed at exploring the effects of ORAI1 on TGF-β1-induced EMT process in CRC cells. Herein, we confirmed ORAI1 expression was higher in CRC tissues than in adjacent non-cancerous tissues by using immunohistochemical staining and Western blot analysis. Higher ORAI1 expression was associated with more advanced clinical stage, higher incidence of metastasis and shorter overall survival. We compared ORAI1 expression in SW480 and SW620 cells, two CRC cell lines with the same genetic background, but different metastatic potential. We found ORAI1 expression was significantly higher in SW620 cells which exhibited higher EMT characteristics. Furthermore, knockdown of ORAI1 suppressed the EMT of SW620 Cells. After induced the EMT process in SW480 cells with TGF-β1, we found treatment of TGF-β1 showed a significant increase in cell migration along with the loss of E-cadherin and an increase in N-cadherin and Vimentin protein levels. Also, TGF-β1 treatment increased ORAI1 expression and was closely associated with the increase of SOCE. Silencing ORAI1 significantly suppressed Ca2+ entry, reversed the changes of EMT-relevant marks expression induced by TGF-β1, and inhibited TGF-β1-mediated calpain activation and cell migration. Finally, we blocked SOCE with 2-APB (2-Aminoethyl diphenylborinate), a pharmacological inhibitor. Interestingly, 2-APB and sh-ORAI1 both exhibited similar inhibition effects to the SW480 cells. In conclusion, our results demonstrated that ORAI1 could mediate TGF-β-Induced EMT by promoting Ca2+ entry and calpain activity in Colorectal Cancer Cells.

Hct 116

Colorectal cancer (CRC) is a vital cause of cancer morbidity and mortality. 50% of CRC patients suffer from an aggressive metastatic disease which ultimately fallout in death. In metastatic cancer, tumour cells migrate, invade, and finally colonise to the distant organ by degrading their attachments with the extracellular matrix. Parthenolide (PTL) is a secondary metabolite of feverfew (Tanacetum parthenium) plant. It shows its cytotoxic effect towards cancer cells via different cellular signalling pathways like inhibition of NF-κB, STAT3, MAPK, JNK pathways, activation of p53 etc. In the present study, we have assessed anti-cancer and anti-metastatic potential of PTL against human HCT-116 metastatic colorectal cancer cells. Analysis of cellular oxidative status (GSH/GSSG) of PTL treated HCT-116 cells showed a significant decrease (p<0.05) in GSH level while GSSG level was increased significantly (p<0.05) on PTL treatment. PTL also increased the amount of intracellular reactive oxygen species. The qRT-PCR analysis revealed that PTL down-regulates c-fos, c-jun and N-cadherin expression and up-regulates E-cadherin expression indicating inhibition of cell migration and metastasis by EMT pathway. PTL inhibited the MMP-9 expression in a dose-dependent fashion and inhibited cancer cell migration by regulating Wnt/β-catenin signalling through the up-regulation of DKK-1 protein expression indicating PTL has a promising anti-cancer potential against HCT-116 metastatic colorectal carcinoma cells.
