Relative expression of KLK5 to LEKTI is associated with aggressiveness of oral squamous cell carcinoma

Abstract: Highlights Approximately 650,000 people will be diagnosed this year with cancers of the oral cavity and pharynx worldwide. The absence of biomarkers for the disease early detection contributes to the late diagnosis. Despite some advances with regards to treatment, overall survival has not significantly improved in decades. We have shown that increased relative mRNA expression of KLK5 to LEKTI is associated with disease’s poor outcome. … Show more

“…Cal 27 are derived from a human tongue SCC [20]. Generation of Cal 27 KLK5 knockout cells was previously reported [21]. Both WT and KLK5 knockout Cal 27 cells were authenticated by STR profiling (DATAPEP-FMUSP, Sao Paulo, SP, Brazil) with the following results: TH01 6, 9.3; D5S818 11, 12; D13S317 10, 11; D7S820 10; D16S539 11, 12; CSF1PO 10, 12; vWA 14, 17; TPOX 8; Amelogenin X. HEK293T cells are from ATCC and were not further authenticated (Catalog# CRL-3216, Manassas, VA, USA).…”

“…The Scratch assay was performed as previously described 21 . Briefly, WT or KLK5 KO Cal 27 cells (2 × 10 5 cells) were cultured on glass coverslips, serum-starved for 16 h and treated or not with hrMatriptase.…”

“…As células silenciadas para KLK5 migravam e proliferavam-se menos, quando comparadas às células que expressavam KLK5. Além do mais, em xenotransplantes dessas células nos camundongos nude, a ausência de KLK5 contribuiu para a diminuição do crescimento dos tumores gerados, sugerindo que não apenas os níveis absolutos de KLK5, mas a expressão relativa de KLK5 para LEKTI, é que provavelmente está associada a um pior prognóstico do carcinoma de boca (ALVES; KODAMA; DA SILVA; GOMES et al, 2021).…”

“…Em conjunto estes resultados podem explicar, em parte, os dados contraditórios da expressão de KLK5 nos carcinomas que, em geral, é avaliada independentemente de LEKTI, de forma absoluta MILLER;LIU et al, 2016;LEUSINK;VAN DIEST;FRANK;BROEKHUIZEN et al, 2015;PETTUS;DAVIS et al, 2009). Além do mais, no estudo de ALVES; KODAMA; DA SILVA; GOMES et al (2021), foi feita uma análise de bioinformática em um banco de dados de 570 carcinomas de cabeça e pescoço, associando a expressão do mRNA de LEKTI e KLK5 à características clínicas provenientes destes tumores. Os resultados demonstraram que menores níveis de mRNA de LEKTI estão associados a uma menor sobrevida, o mesmo não acontece com o mRNA para KLK5.…”
