  Recently, clinical studies have revealed that smoking can contribute to the poor prognosis of colorectal cancer (CRC) and, additionally, can be a risk factor for pulmonary metastasis of CRC. However, there has been no basic research regarding the underlying molecular mechanism. The purpose of this study was to clarify the mechanism by which smoking causes pulmonary metastasis of CRC.
 
  First, pulmonary metastasis model mice inhaled cigarette smoke or air (control) for 1 h once a day for 3 weeks. We attempted to clarify the effect of smoking on the incidence of pulmonary metastasis. On the 15th day, CMT-93 cells were injected into the tail vein. At 6 and 8 weeks following injection, the extent of pulmonary metastasis was evaluated using in vivo micro CT. After the last CT examination, the mice were sacrificed, and the lungs were extracted for pathological examination.
 
  The number of mice with pulmonary metastases in the smoking group was significantly higher than in the control group. Three weeks of smoking induced mild inflammation in the lungs, as evidenced by increases in the levels of IL-6 and TNF-α in bronchoalveolar lavage. Moreover, the adhesion-related molecule ICAM-1 was overexpressed in pulmonary tissue, which allowed drained cancer cells to remain in the lung and contribute to the formation of pulmonary metastasis.
 
  Collectively, cigarette smoking may contribute to the pathogenesis and development of pulmonary metastasis in CRC through enhancement of adhesion and inflammation.

Aberrant miR-424 expression is found in several tumors where they can function as either oncogenes or tumor-suppressor genes. Meanwhile, miR-424 is also affected by the reorganization of many other non-coding RNAs such as lncRNA and cirRNA. Several studies have found that miR-424 participates in proliferation, differentiation, apoptosis, invasion, angiogenesis, and drug resistance, and plays an important role in the tumorigenesis and progression of tumors. This review will focus on the recent progress of research on miR-424 in tumors.
  EZH2 is the catalytic subunit of the polycomb repressive complex 2 (PRC2) and has been documented as an oncogene in breast cancer. The microRNA (miR)-101-3p can suppress breast cancer progression by targeting with EZH2. Syn-cal14.1a, a synthetic peptide derived from 
  (Cal14.1a), can decrease the cell viability and activate the cell apoptosis in cancer. In this study, we explored whether the synergy of miR-101-3p mimic and syn-cal14.1a could inhibit the expression of EZH2. We also investigated this binding treatment's effects on the suppression of breast cancer cells.
 
  MiR-101-3p mimic was transfected and syn-cal14.1a was added in SK-BR-3 and MCF-7 breast cancer cells. The expression of EZH2 protein level was determined. Then, cell proliferation, migration, invasion, and apoptosis were observed.
 
  MiR-101-3p and syn-cal14.1a, when applied together, exerted a synergistic anti-EZH2 expression in breast cancer cells.  https://www.selleckchem.com/products/sw-100.html  The combination of miR-101-3p and syn-cal14.1a synergistically suppressed the EZH2-induced breast cancer cell migration, invasion, and proliferation. In parallel, this synergy treatment was able to promote the apoptosis of breast cancer cells. To our knowledge, this is the first report describing inhibition of EZH2 in human breast cancer cell lines by syn-cal14.1a.
 
  The anti-EZH2 roles of miR-101-3p and/or syn-cal14.1a could provide an effective therapeutic strategy in breast cancer. These data provide significant insights into molecular mechanisms of breast cancer and may have benefits in clinical therapeutics for breast cancer.

  The tumor protein p53-inducible nuclear protein 2 (TP53INP2), an autophagy protein, is essential for autophagosome formation. The deregulation of autophagy is associated with multiple human diseases, including cancer. The present study aims to explore the role of TP53INP2 in bladder cancer.
 
  Quantitative real-time polymerase chain reaction was used to detect the mRNA level. Relative TP53INP2 protein expression was detected by immunohistochemistry and Western blot. The effect of TP53INP2 silencing on the proliferation, migration, and invasion of bladder cancer cells was investigated by CCK-8 detection kit and transwell assay. In addition, transfection and immunofluorescence were performed.
 
  In this study, we report that high expression of TP53INP2 is correlated with poor patient survival in bladder cancer. Results demonstrate that the depletion of TP53INP2 inhibits the migration, invasion, and epithelial-to-mesenchymal transition (EMT) of bladder cancer cells. The underlying mechanism was explored. Results show that the TP53INP2 knockdown suppresses EMT by inhibiting the active non-phosphorylated β-catenin and decreasing the Snail1 levels. Furthermore, the glycogen synthase kinase-3 beta (GSK-3β) inhibitor IM-12 abrogates the effect of TP53INP2 silencing. Interestingly, the induction of autophagy partially abrogates the TP53INP2 knockdown-induced decrease in active β-catenin and inhibition of migration and invasion in bladder cancer cells.
 
  In summary, our results show that the downregulation of TP53INP2 inhibits EMT via the GSK-3β/β-catenin/Snail1 pathway in bladder cancer. The findings of this study uncover the novel role of TP53INP2 and offer new insights into bladder cancer clinical therapy.
