Recent advances in the enzymology of transcription and chromatin regulation have led to the discovery of proteins that play a prominent role in cell differentiation and the maintenance of specialized cell functions. Knowledge about post-synthetic DNA and histone modifications as well as information about the rules that guide the formation of multimolecular chromatin-bound complexes have helped to delineate gene-regulating pathways and describe how these pathways are altered in various pathological conditions. The present review focuses on the emerging area of therapeutic interference with chromatin function for the purpose of cancer treatment and immunomodulation.

Historically considered downstream effects of tumorigenesis-arising from changes in DNA content or chromatin organization-nuclear alterations have long been seen as mere prognostic markers within a genome-centric model of cancer. However, recent findings have placed the nuclear envelope (NE) at the forefront of tumor progression, highlighting its active role in mediating cellular responses to mechanical forces. Despite significant progress, the precise interplay between NE components and cancer progression remains under debate.

The B lymphoma Mo-MLV insertion region 1 homolog (Bmi-1) protein of the polycomb complex is an essential mediator of the epigenetic transcriptional silencing by the chromatin structure. It has been reported to be crucial for homeostasis of the stem cells and tumorigenesis. Though years of investigation have clarified Bmi-1's transcriptional regulation, post-translational modifications, and functions in controlling cellular bioenergetics, pathologies, and DNA damage response, the full potential of this protein with so many diverse roles are still unfulfilled.

Nucleosomes, the chromatin building blocks, play an important role in controlling DNA and chromatin accessibility. Nucleosome remodeling and the incorporation of distinct histone variants confer unique structural and biochemical properties, influencing the targeting of multiple epigenetic pathways, particularly DNA methylation. This stable epigenetic mark suppresses transposable element expression in plants and mammals, serving as an additional layer of chromatin regulation.

Prostate cancer is a heterogeneous disease with a slow progression and a highly variable clinical outcome. The tumor suppressor genes PTEN and TP53 are frequently mutated in prostate cancer and are predictive of early metastatic dissemination and unfavorable patient outcomes. The progression of solid tumors to metastasis is often associated with increased cell plasticity, but the complex events underlying TP53-loss-induced disease aggressiveness remain incompletely understood.

Cancer is a leading cause of mortality worldwide. The evolving role of epigenetics and tumor microenvironments of cancer pose significant challenges to the management of cancer. Besides genetics, epigenetic changes play a crucial role in the alteration of cellular machinery, progression, metastasis, epithelial-mesenchymal transition, and chemoresistance.
