RBM15 Promates the Proliferation, Migration and Invasion of Pancreatic Cancer Cell Lines

Simple Summary This article reports that RBM15 is correlated with pancreatic cancer progression and is an essential prognostic biomarker in pancreatic cancer patients and is correlated with progression by bioinformatic integrated analysis, clinical information statistical analysis and wet experiments. (1) Background: Pancreatic cancer is increasingly becoming the leading cause of cancer deaths worldwide. In eukaryotic cells, m6A is the most abundant mRNA methylation modification. (2) Methods: We performed a bioinformatic multidimensional analysis using files containing the clinical data of patients and m6A-related gene expression differences downloaded from web-based databases, and performed a statistical analysis and image mapping mainly using R-package. Next, we studied the RBM15 expression in cancer and paracancerous tissues. We then validated these findings in two cell lines by western blot, PCR, Transwell, CCK-8, and EDU animal models. (3) Results: We discovered that RBM15 was highly expressed in pancreatic cancer patients and that it is a significant cause of poor prognosis. Its association with lymphatic T cell family aggregation was established through immune infiltration analysis. A retrospective analysis of data from clinical patient specimens revealed that high expression of RBM15 in patients was closely and positively correlated with preoperative glucose values, gender, and lymphocyte counts. Results from cellular experiments and animal experiments indicated that when the RBM15 gene was silenced, cell proliferation, migration, and metastasis were inhibited. (4) Conclusions: We propose that RBM15 plays a key role in the progression of pancreatic cancer by promoting tumor proliferation, migration and metastasis.

Automated summary

This study found that RBM15 is correlated with pancreatic cancer progression and is an essential prognostic biomarker in pancreatic cancer patients. The high expression of RBM15 is associated with lymphatic T cell family aggregation. Cellular and animal experiments showed that silencing RBM15 gene can inhibit cell proliferation, migration, and metastasis.
