Additionally, both E. faecalis biofilm formation and the biomass of 1-day-old E. faecalis biofilms were significantly reduced by GH12 (P less then 0.05). Elimination of E. faecalis in biofilms from root canal walls was achieved through irrigation with 64.0 mg/L GH12 for 30 min. CLSM analysis revealed that GH12 at 64.0 mg/L was most effective in eliminating bacteria within dentinal tubules (P less then 0.05). CONCLUSION In a laboratory setting, and when used as an irrigant, GH12 suppressed E. faecalis, downregulated specific virulence and stress-associated genes, eliminated intracanal E. faecalis protected by biofilms and killed bacteria in dentinal tubules. These results emphasise the need for preclinical and clinical studies to explore the potential of GH12 as an antimicrobial agent in root canal treatment. This article is protected by copyright.

It is known that Bcl-x splicing is deregulated and is involved in multiple malignant cancer initiation and chemotherapy resistance, including CML. The aim of the present study was to correct the abnormal splicing of Bcl-x in CML and investigate the subsequent malignant phenotype changes, especially response to IM. The aberrant Bcl-x splicing in CML cells was effectively restored using vivo-Morpholino Antisense Oligomer (vMO). CCK-8 cell viability assay and flow cytometry showed that restoring of Bcl-x splicing increases IM-induced growth inhibition and apoptosis of K562 cells. Moreover, a more significant similar phenomenon was observed in imatinib-resistant CML cell lines K562/G01. Finally, establishment of CML xenograft model had also proved that correcting Bcl-x splicing in vivo can also enhance the anti-tumor effect of IM. Our findings sugges
