A total of 11 micro-invasive and 32 early invasive OSCC cases were assessed for core features of EMT. The predominant feature defining EMT found was dense inflammatory infiltrate in both microinvasive (91%) and early invasive OSCC (88%) followed by cell individualization in 82% of microinvasive and 75% of early invasive OSCC, which was then followed by other features. Reporting EMT in histopathological reports on a daily basis can aid in early diagnosis of OSCC as well as understanding carcinogenesis in early stages.

After PRR11 was up-regulated, cell proliferation, invasion, migration and apoptosis were detected by the cell counting kit-8 method, Transwell, scratch, and flow cytometry. PRR11 is highly expressed in a variety of malignant tumors, including osteosarcoma tissue and cells, and has a significant impact on prognosis. Univariate Cox regression analysis revealed that PRR11 was an independent prognostic factor for osteosarcoma. The gene set enrichment analysis results showed that the differential genes were mainly enriched in the biological process of the cell cycle; the protein-protein interaction network mainly interacted with the regulatory genes of the cell cycle. PRR11 promotes the invasion, migration, and proliferation of osteosarcoma cells and inhibits their apoptosis. Comprehensive bioinformatics analysis revealed that PRR11 promotes the malignancy of osteosarcoma cells mainly by participating in cell cycle regulation, and has an important impact on osteosarcoma prognosis.
