Krüppel-like Factor 6 Suppresses the Progression of Pancreatic Cancer by Upregulating Activating Transcription Factor 3
Background: As a member of the Krüppel-like factor (KLFs) family, Krüppel-like factor 6 (KLF6) plays a critical role in regulating key cellular functions. Presently, scholars have proved the important role of KLF6 in the tumorigenesis of certain cancers through a large number of experiments. However...

| description | Background: As a member of the Krüppel-like factor (KLFs) family, Krüppel-like factor 6 (KLF6) plays a critical role in regulating key cellular functions. Presently, scholars have proved the important role of KLF6 in the tumorigenesis of certain cancers through a large number of experiments. However, gaps still remain in our knowledge of the role of KLF6 in pancreatic cancer (PAAD). Therefore, this paper mainly investigates the role of KLF6 in the progression of pancreatic cancer. Methods: The expression pattern of KLF6 in pancreatic cancer was explored in pancreatic cancer tissues and cell lines. Then, we investigated the prognostic value of KLF6 in pancreatic cancer by immunohistochemical assays. Next, Cell Counting Kit-8 (CCK8) and clone information assays were employed to explore the proliferation of PAAD affected by KLF6. The metastasis and epithelial-mesenchymal transition (EMT) abilities affected by KLF6 were identified through transwell invasion as well as migration assays and western blots. Finally, the TRRUST tool was used to analyze the potential targeted genes of KLF6. The results were verified by Quantificational Real-time Polymerase Chain Reaction (qRT-PCR), western blot and rescue assays. Results: KLF6 expresses lowly in pancreatic cancer compared to corresponding normal tissues and relates to poor survival times. Overexpression of KLF6 inhibits the proliferation, metastasis, and EMT progression in pancreatic cancer cells. Further studies suggest that KLF6 could upregulate ATF3 in PAAD. Conclusions: Our results suggest that KLF6 can be a useful factor in predicting the prognosis of PAAD patients and that it inhibits the progression of pancreatic cancer by upregulating activating transcription factor 3 (ATF3). |
