Upregulation of the interferon-inducible antiviral gene RSAD2 in neuroendocrine prostate cancer via PVT1 exon 9 dependent and independent pathways.

PVT1 exon 9 overexpression is a newly uncovered aberration in prostate cancer (PCa). We have previously demonstrated the exon 9 region of PVT1 is overexpressed in some patient PCa tissues and causes development of neuroendocrine prostate cancer (NEPC) in vitro and in vivo. In this study, we focused on elucidating downstream mechanisms induced by PVT1 exon 9 overexpression with the goal of further understanding its role in NEPC development.

Epigenetic modifications in solid tumor metastasis in people of African ancestry.

This review focuses on the critical role of epigenetic modifications in solid tumor metastasis, particularly in people of African ancestry. Epigenetic alterations, such as DNA methylation, histone modifications, alterations in non-coding RNAs, and mRNA methylation, significantly influence gene expression, contributing to cancer development and progression. Despite the primary focus on populations of European, American, and Asian descent in most cancer research, this work emphasizes the importance of studying the unique genetic and epigenetic landscapes of African populations for a more inclusive approach in understanding and treating cancer.
