Abstract
Abstract
Multiple myeloma (MM) is a clonal plasma cell (PC) cancer that is preceded by the benign conditions monoclonal gammopathy of undetermined significance (MGUS) and smoldering MM (SMM). While MGUS/SMM PCs are not proliferative, many of the oncogenes and chromosomal abnormalities in MM PCs are also present in MGUS/SMM. Since oncogenic stress is known to induce cellular senescence, we hypothesized that MGUS/SMM PCs may be in a senescent-like state. Our analysis of a published human dataset (GSE5900) revealed that compared to healthy PCs, MGUS/SMM PCs had significantly increased expression of senescence markers CDKN1A and GADD45A (FDR<0.05). Gene Set Enrichment Analysis (GSEA) showed significant enrichment in MGUS/SMM PCs of our customized senescence phenotyping gene sets (q<0.25). We next evaluated the KaLwRij MGUS mouse model. 10-mo-old female KaLwRij mice were treated with placebo or senolytics (dasatinib+quercetin, D+Q). D+Q treatment significantly reduced PCs compared to placebo, while restoring B cell number and functional gene expression. PCs isolated from D+Q-treated KaLwRij mice exhibited significant reductions in Myc and Il1b expression (p<0.05) versus placebo and a trend towards reduced Trp53 expression (p=0.13), supporting that senescent PCs are targeted by D+Q. Single-cell RNA-seq and single sample (ss)GSEA of 24-mo-old KaLwRij PCs revealed a PC subset enriched for the ‘Plasma Cell Senescence’ gene set, which included genes from our customized gene sets that were differentially expressed in the human PCs dataset GSE5900. Notably, PCs in this subset showed enrichment for ‘Inflammatory SASP’ (median: 15.26%) and ‘Interferon (IFN) SASP’ (39.36%) gene sets. The IFN-SASP is characteristic of late senescence, driven by the accumulation of transposable elements. In the GSE5900 dataset, we found significant enrichment of ‘IFN-SASP’ in SMM (q<0.25) but not MGUS PCs. Further, whole transcriptome RNA-sequencing showed that SMM PCs had increased expression of LINE1 retrotransposon L1HS in relation to normal PCs (FDR<0.1), but not MGUS (FDR=0.83) or MM (FDR=0.5) PCs. Immunostaining confirmed increased cytosolic DNA:RNA hybrids in SMM (median frequency of cells exceeding the intensity threshold = 33%) versus MGUS (16.4%), MM (4.4%), and healthy PCs (1.5%), which is consistent with cytosolic DNA-mediated activation of the IFN SASP in SMM PCs. When these same patients were redistributed according to disease progression, L1HS was higher in patients with progressing SMM and newly diagnosed MM (NDMM) (FDR<0.1) versus patients with stable MGUS (FDR=0.56) or advanced MM (FDR=0.38). Increased DNA:RNA staining was observed in progressing SMM PCs (median frequency = 41%), but the results for NDMM patients (4.4%) and advanced MM (3%) were comparable to healthy or stable patients (3.5%). These data demonstrate that MGUS and SMM PCs exhibit senescence features, suggest mechanisms that may contribute to MM tumorigenesis, and show that pharmacological ablation of senescent cells may prevent progression from MGUS/SMM to MM.

Abstract
Adipose tissue inflammation and dysfunction are associated with obesity-related insulin resistance and diabetes, but mechanisms underlying this relationship are unclear. Although senescent cells accumulate in adipose tissue of obese humans and rodents, a direct pathogenic role for these cells in the development of diabetes remains to be demonstrated. Here, we show that reducing senescent cell burden in obese mice, either by activating drug-inducible "suicide" genes driven by the p16Ink4a promoter or by treatment with senolytic agents, alleviates metabolic and adipose tissue dysfunction. These senolytic interventions improved glucose tolerance, enhanced insulin sensitivity, lowered circulating inflammatory mediators, and promoted adipogenesis in obese mice. Elimination of senescent cells also prevented the migration of transplanted monocytes into intra-abdominal adipose tissue and reduced the number of macrophages in this tissue. In addition, microalbuminuria, renal podocyte function, and cardiac diastolic function improved with senolytic therapy. Our results implicate cellular senescence as a causal factor in obesity-related inflammation and metabolic derangements and show that emerging senolytic agents hold promise for treating obesity-related metabolic dysfunction and its complications.

Abstract
Physical function declines in old age, portending disability, increased health expenditures, and mortality. Cellular senescence, leading to tissue dysfunction, may contribute to these consequences of aging, but whether senescence can directly drive age-related pathology and be therapeutically targeted is still unclear. Here we demonstrate that transplanting relatively small numbers of senescent cells into young mice is sufficient to cause persistent physical dysfunction, as well as to spread cellular senescence to host tissues. Transplanting even fewer senescent cells had the same effect in older recipients and was accompanied by reduced survival, indicating the potency of senescent cells in shortening health- and lifespan. The senolytic cocktail, dasatinib plus quercetin, which causes selective elimination of senescent cells, decreased the number of naturally occurring senescent cells and their secretion of frailty-related proinflammatory cytokines in explants of human adipose tissue. Moreover, intermittent oral administration of senolytics to both senescent cell-transplanted young mice and naturally aged mice alleviated physical dysfunction and increased post-treatment survival by 36% while reducing mortality hazard to 65%. Our study provides proof-of-concept evidence that senescent cells can cause physical dysfunction and decreased survival even in young mice, while senolytics can enhance remaining health- and lifespan in old mice.

Abstract
Although there has been extensive characterization of the Wnt signaling pathway in the osteoblast lineage, the effects of Wnt proteins on the osteoclast lineage are less well studied. We found that osteoclast lineage cells express canonical Wnt receptors. Wnt3a reduced osteoclast formation when applied to early bone-marrow macrophage (BMM) osteoclast differentiation cultures, whereas late addition did not suppress osteoclast formation. Early Wnt3a treatment inactivated the crucial transcription factor NFATc1 in osteoclast progenitors. Wnt3a led to the accumulation of nuclear β-catenin, confirming activation of canonical Wnt signaling. Reducing low-density lipoprotein receptor-related proteins (Lrp) 5 and Lrp6 protein expression prevented Wnt3a-induced inactivation of NFATc1; however, deletion of β-catenin did not block Wnt3a inactivation of NFATc1, suggesting that this effect was mediated by a noncanonical pathway. Wnt3a rapidly activated the cyclic adenosine monophosphate (cAMP)/protein kinase A (PKA) pathway and pharmacological stimulation of cAMP/PKA signaling suppressed osteoclast differentiation; Wnt3a-induced NFATc1 phosphorylation was blocked by inhibiting interactions between PKA and A-kinase anchoring proteins (AKAPs). These data indicate that Wnt3a directly suppresses osteoclast differentiation through both canonical (β-catenin) and noncanonical (cAMP/PKA) pathways in osteoclast precursors. In vivo reduction of Lrp5 and Lrp6 expressions in the early osteoclast lineage via Rank promoter Cre recombination reduced trabecular bone mass, whereas disruption of Lrp5/6 expression in late osteoclast precursors via cathepsin K (Ctsk) promoter Cre recombination did not alter the skeletal phenotype. Surprisingly, reduction of Lrp5/6 in the early osteoclast lineage decreased osteoclast numbers, as well as osteoblast numbers. Published studies have previously noted that β-catenin signaling is required for osteoclast progenitor proliferation. Our in vivo data suggest that Rank promoter Cre-mediated deletion of Lrp5/6 may similarly impair osteoclast progenitor proliferation.
