ERG overexpression

HDAC7 promotes the growth of human and mouse AEL cells both in vitro and in vivo through its non-enzymatic functions. Our study provides experimental evidence that TP53 deficiency and ERG overexpression are necessary and sufficient for the development of AEL and highlights HDAC7 as a promising therapeutic target for this disease.

These results suggested that a certain threshold level of LDB1 expression enables FLI1 to block erythroid differentiation. Overall, FLI1 controlled the commitment of MEP to either erythroid or megakaryocytic lineage through an intricate regulation of GATA1/GATA2, LDB1 and ERG, exposing multiple targets for cell fate commitment and therapeutic intervention.

Statistical analysis was done with Statistica and R software. When analyzing the expression of miRNAs some differences could be seen, but after correction for multiple comparisons was applied, these were found to be non- significant.

Using a large, diverse, national cohort, we observed considerable variations in gene expression profiles across groups by race, age, Gleason grade group, and geographic region that can address the genomic underpinnings of sociodemographic and geographic variation in prostate cancer outcomes.

Overexpression of FABP4 could effectively block the inhibition role of NKX2-1-AS1 silencing in lymphangiogenesis in H441 and H661 cells. This study provided evidence that NKX2-1-AS1 regulated FABP4 transcription by binding to ERG to facilitate the proliferation and migration of LUAD cells and tube formation of HLECs, thus participating in lymphangiogenesis.

In conclusion, our results indicate that UF and MF PCa have relevant and consistent molecular differences. The analysis of an immunohistochemical panel, composed by PTEN, SPOP, SLC45A3, ETV1 and ERG, could be useful to predict outcome in MF cases.

In mice, prostate-specific Snd1 deletion reduces cancer growth and tumor burden in a prostate cancer model (PB-Cre/Pten/ERG mice), Moreover, we find a significant overlap between prostate transcriptional signatures of ERG and SND1. These findings highlight SND1's crucial role in prostate tumorigenesis, suggesting SND1 as a potential therapeutic target in prostate cancer.

Like the well-known disease genes GATA2 and RUNX1, ERG is also a member of the transcription factor heptad involved in HSC maintenance and differentiation. ERG adds to a growing list of genes whose unregulated expression contributes to HM and other cancers.Identification of causal germline ERG variants like those outlined in this study, has direct clinical implications for patient and family management including diagnosis, counselling, surveillance and treatment strategies such as selection of bone marrow transplant donors and potential for targeted therapies including gene and cell therapy.

This study indicates that miR-4482 and -3912 can suppress the ERG expression and its target genes, thereby, halt prostate cancer progression. These miRNAs may be employed as a potential therapeutic target for the miRNA-based therapy against prostate cancer.

Although, at some degree, ERG expression seems to be associated with the morphological features of prostate cancer, different studies reported controversial results. However, expression of PTEN is more clearly associated with the pathology and clinical course of the disease. More research is required to elucidate the role of these molecules in the molecular pathology of prostate cancer, as well as their potential use as therapeutic targets.

Nonetheless, our findings corroborate tissue-based molecular data demonstrating ERG is less overexpressed in AA men’s tumors. These data underscore the importance of considering race in the development of PCa biomarkers.
