Nomogram Incorporating the WNT/β-Catenin Signaling Pathway for Predicting the Survival of Cutaneous Melanoma.

Background: Accurate prediction of the survival of cutaneous melanoma (CM) permits the selection of the optimal treatment. Currently, the TNM stage has limitations in predicting the survival of CM. There is evidence that the WNT/β-catenin signaling pathway has the potential to predict the CM prognosis.

siRNA silencing EZH2 reverses cisplatin-resistance of human non-small cell lung and gastric cancer cells.

Clinical resistance to chemotherapeutic agents is one of the major hindrances in the treatment of human cancers. EHZ2 is involved in drug resistance and is overexpressed in drug-resistant cancer cell lines. In this study, we investigated the effects of EHZ2 on cisplatin -resistance in A549/DDP and AGS/DDP cells.

[Effects of STI571 combined with As₂O₃ on proliferation, apoptosis and caspase 3, Bcl-xL expression of K562 cells].

This study was aimed to explore the effects of STI571 alone or with As₂O₃ on proliferation, apoptosis and caspase 3, bcl-xL mRNA expression of K562 cells, and the molecular mechanism of As₂O₃ enhancing the anti-leukemia effect of STI571 so as to provide the scientific basis for clinical treatment of chronic myeloid leukemia. The effect of drugs on proliferation of K562 cells was assayed by MTT method, the apoptosis rate of K562 cells was detected by flow cytometry with Annexin V/PI double staining, the caspase 3, bcl-xL mRNA expressions of K562 cells were determined by real time quantitative PCR. The results showed that STI571 alone or with As₂O₃ both could inhibit the proliferation of K562 cells.
