“…Moreover, reverse transcriptase inhibitors reduced the amount of cytosolic DNA in old WT HSCs, rescuing their fitness compared with old Tet2 -deficient HSCs in vitro, although whether this approach can abrogate Tet2 -deficient HSPC expansion in vivo is unknown ( 83 ). Notably, others have suggested implementing reverse transcriptase inhibitors as rejuvenating treatments to correct aberrant expression of repetitive elements as well ( 148 ).…”

Clonal hematopoiesis of indeterminate potential (CHIP) is characterized by the selective expansion of hematopoietic stem and progenitor cells (HSPCs) carrying somatic mutations. While CHIP is typically asymptomatic, it has garnered substantial attention due to its association with the pathogenesis of multiple disease conditions, including cardiovascular disease (CVD) and hematological malignancies. In this Review, we will discuss seminal and recent studies that have advanced our understanding of mechanisms that drive selection for mutant HSPCs in the BM niche. Next, we will address recent studies evaluating potential relationships between the clonal dynamics of CHIP and hematopoietic development across the lifespan. Next, we will examine the roles of systemic factors that can influence hematopoietic stem cell (HSC) fitness, including inflammation, and exposures to cytotoxic agents in driving selection for CHIP clones. Furthermore, we will consider how — through their impact on the BM niche — lifestyle factors, including diet, exercise, and psychosocial stressors, might contribute to the process of somatic evolution in the BM that culminates in CHIP. Finally, we will review the role of old age as a major driver of selection in CHIP.
