The Cripto-1 (CR-1) derived EGF-CFC family was overexpressed in tumor development enhancing proliferation, epithelial-mesenchymal transition (EMT) and migration of tumor cells. However, correlation between CR-1 and prostate cancer (PCa) remains still unclear. In the present study, we proved that CR-1 was expressed in PCa and its function was in the progression of PCa. Compared with benign prostatic hyperplasia (BPH) tissues, we confirmed that PCa tissues had high expression of CR-1 by immunohistochemistry and statistical data showed that CR-1 promoted properties of EMT in PCa tissues, including the downregulation of the cell adhesion molecules β-catenin (membrane) and E-cadherin while upregulating transcription factors β-catenin...

Yifei Chen, Yi Zhang, Jianhuai He, Ying Fu, Changwei Lin, Xiaorong Li
Downregulation of miR-133b has been reported in multiple types of malignancies including colorectal cancer (CRC). We previously confirmed that TAp63 actively translates microRNA-133b (miR-133b) transcripts. While the presence of miRNA mutations have frequently been described in CRC, most CRCs do not show any variation in the miR‑133b coding sequence. Therefore, it is important to elucidate the relationship between TAp63 and miR-133b, and identify other mediators of miR-133b downregulation in CRC. The expression of TAp63 was detected by RT-qPCR, western blotting, immunohistochemistry (IHC) and densitometric analysis using Image-Pro Plus 6...

Lung adenocarcinoma is the most common type of lung cancer and found in both smokers and non-smokers, but the treatment of lung cancer is limited. ITR-284 has been shown to be a potent carboxamide-derived anticancer agent and to induce apoptosis in leukemia and colon cancer cells. However, little is known whether ITR-284 has anticancer activity in human lung adenocarcinoma cells through induction of apoptosis and suppression of migration in vitro. We showed that ITR-284 inhibited human lung cancer A549 cells using the thiazolyl blue tetrazolium bromide (MTT) assay and evoked apoptosis via the cell cycle distribution at S phase arrest...

Prostatic carcinoma is the most aggressive tumor in adult men. Warburg effect is an important characteristic of tumor cell metabolism including prostate cancer cells, in which hexokinase 2 (HK2), a major rate-limiting enzyme involved in Warburg effect, is selectively upregulated. The lectin PCL is a mannose binding lectin which induces tumor cell apoptosis and autophagy. In the present study, we report that PCL could lower glucose consumption and lactate production, shift the Warburg effect by inhibiting the expression of HK2 in PC3 cells and the suppression of HK2 by siRNA reversed the effect of PCL on glucose consumption and lactate production...
