Figure 5. TPT1-AS1 promotes CRC progression via TPT1. (A) TPT1 expression was restored in TPT1-AS1 depletion cells via transfecting the pcDNA3.1-TPT1 plasmid. MTT (B) and clone formation assays (C) showed that ectopic expression of TPT1 could remarkably relieved the suppressive effects on cell viability and proliferation causing by TPT1-AS1 knockdown. (D) Restoring TPT1 expression could obviously attenuated the promotive effects on cell adhesion inducing by TPT1-AS1 depletion (magnification 200x). Wound scratch (magnification 100x) (E) and Transwell assays (magnification 200x) (F) showed that ectopic expression of TPT1 could obviously relieved the suppressive effects on cell migration and invasion causing by TPT1-AS1 knockdown. *P<0.05.
