ABSTRACT
Purpose: The progress of prostate cancer entails complex contemporaneous tumor developmental events in diverse stages that they are still yet to be clarified. miRNAs might accompany to balance between regulatory and cytotoxic T cells in tumors. Here, we investigated miRNAs and Regulatory T cell (Treg) marker FOXP3 expressions within prostate cancer spectrum. Methods: Thirty-eight prostate cancer patients enrolled within two groups to the study as having Gleason Score ≤ 7 (Group-1) and ≥ 8 (Group-2) that compared to 19 benign prostate hyperplasia controls. Twelve miRNAs expressions were analyzed by real time PCR from paraffin-embedded prostate tissue samples. Correlations between serum PSA levels, immunohistochemical staining of CD3, CD4, FOXP3 and miRNA expressions were analyzed. Results: In our study, hsa-let7c-3p significantly 1,52 (p=0.018) and 1,84 (p=0.0095) fold down- regulated whereas, miR-141-3p was significantly 2,36 (p=0.0006) and 2,24 (p=0.001) fold upregulated in the prostate cancer patients compared to benign prostate hyperplasia in group 1 and 2, respectively. Only CD4 (p=0.004) and PSA (p<0.001) have statistically significant differences among groups when compared to benign prostate hyperplasia. miR-143-p, miR-221-3p, hsa-let7c-3p and miR-17-3p expressions were significantly correlated with regulatory T cell marker FOXP3 expression. Conclusions: For the first time, we reported significantly altered expression levels of miRNAs (miR-let7c, miR221, miR-146a, miR-141, miR-143, miR17) and correlations between Treg marker FOXP3 in the aggressive prostate cancer patients suggesting that prostate cancer progression might be under the regulation of crosstalk between Tregs and miRNAs (AU)
RESUMEN
Propósito: El progreso del cáncer de próstata implicaeventos complejos de desarrollo tumoral contemporáneo endiversas etapas que aún no se han aclarado. Aquí, investigamos los MIRNAs y el marcador de células T reguladoras(Treg) FOXP3 expresiones dentro del espectro de cáncer depróstata.Métodos: Treinta y ocho pacientes con cáncer depróstata inscritos dentro de dos grupos para el estudio unapuntuación de Gleason ≤ 7 (Grupo-1) y ≥ 8(Grupo-2)que en comparación con 19 controles benignos de hiperplasia de próstata. Doce expresiones miRNAs fueron analizadas por PCR en tiempo real a partir demuestras detejidoprostático incrustado en parafina. Se analizaronlos nivelesde PSA séricos de correlaciónsetween, la tinción inmunohistoquímica de expresiones CD3, CD4, FOXP3 y miRNA.Resultados: En nuestro estudio, has-let7c-3p significativamente 1,52 (p-0.018) y 1,84 (p-0. 0095) plegarsehacia abajo, mientras que, miR-141-3p fue significativamente 2,36 (p-0.0006) y 2,24 (p-0. 001) plegarse reguladoen los pacientes con cáncer de próstata en comparación conla hiperplasia benigna de próstata en los grupos 1 y 2, respectivamente. Sólo CD4 (p-0.004) y PSA (p<0. 001)tienen diferencias estadísticamente significativas entre losgrupos en comparación con la hiperplasia benigna de próstata. las expresiones miR-143-p, miR-221-3p, has-let7c-3py miR-17-3p se correlacionaron significativamente conlaexpresión FOXP3 del marcador de celda T egulatorio r.Conclusiones: Fo laprimera vez,informamos denivelde expresión significativamente alterado demiRNAs (miR-let7c, miR221, miR-146a, miR-141, miR-143,miR17) y correlaciones entre el marcador Treg DE Treg33en los pacientes agresivos de cáncer de próstata sugiriendoque la progresión del cáncer de próstata podría estar bajo laregulación de la cruz entre Tregtalks y miR.
