The mutated genes, including TET2, DNMT3A, ASXL1, TP53, JAK2, and SF3B1, are also recurrently mutated in myeloid malignancies. Individuals with CHIP have an increased risk of developing a hematologic cancer. Moreover, individuals with CHIP have an elevated risk of all-cause mortality that is significantly attributable to cardiovascular disease, independent of traditional risk factors. The mechanism for this increased risk is likely linked to increased inflammation driven by mutated macrophages, in part through inflammasome activation. This has broadened our understanding of how chronic diseases are influenced by CHIP and of the mechanistic role of inflammation in these disorders.

Bromodomain and extraterminal domain (BET) proteins are powerful transcriptional coregulators often found as part of oncogenic transcriptional programs. The bromodomain functionality of BET proteins is highly druggable, and several product candidates are in clinical testing. While initial clinical data created doubt about their benefit for cancer patients, more encouraging data recently reported in myelofibrosis patients may promote additional applications of BET inhibitors in oncology as monotherapy and in combination with other therapeutic agents. Moreover, a growing number of approaches to optimize the therapeutic window by tinkering with the property profiles of BET inhibitors may provide additional clinical opportunities. This review provides an update on the status of ongoing activities to exploit BET bromodomain inhibition as a mechanism for cancer therapy.

After initiation, cells acquire additional genetic and epigenetic alterations influenced by tumor-intrinsic and -extrinsic mechanisms, which increase intratumoral heterogeneity, reshape the cell's underlying gene regulatory network, and promote cancer evolution. Furthermore, environmental or therapeutic insults drive the selection of heterogeneous cell states, with implications for cancer initiation, maintenance, and drug resistance. The advancement of single-cell genomics has begun to uncover the full repertoire of chromatin and gene expression states (cell states) that exist within individual tumors. These single-cell analyses suggest that cells diversify in their regulatory states upon transformation by co-opting damage-induced and nonlineage regulatory programs that can lead to epigenomic plasticity. Here, we review these recent studies related to regulatory state changes in cancer progression and highlight the growing single-cell epigenomics toolkit poised to address unresolved questions in the field.

However, in most cases, it remains difficult to disentangle their active contribution to CRC from just a bystander role. This review focuses on the mechanisms described to date by which the CRC-associated microbiota could contribute to CRC. Bacteria like pks+ Escherichia coli, Fusobacterium nucleatum, or enterotoxigenic Bacteroides fragilis have been shown to induce mutagenesis, alter host epithelial signaling pathways, or reshape the tumor immune landscape in several experimental systems. The mechanistic roles of other bacteria, as well as newly identified fungi and viruses that are enriched in CRC, are only starting to be elucidated. Additionally, novel systems like organoids and organs-on-a-chip are emerging as powerful tools to study the direct effect of gut microbiota on healthy or tumor intestinal epithelium. Thus, the expanding knowledge of tumor-microbiota interactions holds promise for improved diagnosis and treatment of CRC.

A promising avenue may be to target the origin of childhood cancers. Here, we review recent advances in tracing the origins of pediatric tumors. Cancer-to-normal cell comparisons by single-cell mRNA sequencing reveal the fetal state of cancer cells, as well as their cell of origin. Recent phylogenetic analyses have uncovered large tissue-resident precursor clones to childhood cancers, which already possess key genomic alterations leading to tumor formation. Both the transcriptional fetalness and genomic status of the premalignant tissue bed provide further avenues for targeted therapy. Overall, these advances begin to describe the precise origins of pediatric tumors and pave the way for novel methods in detecting, treating, and perhaps even preventing childhood cancers.

In this review, we describe how viral oncogenes alter metabolism to increase the synthesis of macromolecules necessary for both viral replication and tumor growth. We then describe how understanding the specific metabolic requirements of virus-infected cells can help guide strategies to improve the efficacy of oncolytic viruses, and highlight immunometabolism and tumor microenvironment research that could also increase the therapeutic benefits of oncolytic viruses.

The tumor-suppressive function of telomeres relies on their ability to initiate DNA damage signaling pathways and downstream cellular events, ranging from cell cycle perturbation to inflammation and cell death. While the tumor-suppressor role of telomeres is undoubtable, recent advances have pointed to telomeres as a major source of many of the genomic aberrations found in both early- and late-stage cancers, including the most recently discovered mutational phenomenon of chromothripsis.

For example, both immune- and genetic-based targeted therapies for cancer underwent numerous failed attempts before biological understanding, improved targets, and optimized drug development matured to facilitate an arsenal of transformational drugs. Similarly, the concept of directly assessing drug sensitivity of primary tumor biopsies-and the use of this information to help direct therapeutic approaches-has a long history with a definitive learning curve.
