Analysis of previously reported BRD4 target genes related to mitochondrial function in senescent fibroblasts.

ABSTRACT: Because BRD4, a major target of ARV825, has been implicated in the regulation of mitochondrial gene expression in cardiomyocytes (DOI: 10.1161/CIRCULATIONAHA.120.047239), we examined whether ARV825-induced cell death in senescent cells is attributable to changes in the expression of mitochondria-related genes. Although senescent cells were eliminated within two days of ARV825 treatment, the mRNA expression levels of mitochondrial-related genes remained unchanged. In contrast, XRCC4— which functions together with DNA ligase IV in non-homologous end joining and has been reported to regulate senolysis (DOI: 10.1038/s41467-020-15719-6)— was downregulated, consistent with previous findings.

MS Annika: A new Cross-Linking Search Engine

Project description:A cross linking mass spectrometry search engine was developed and implemented into Thermo Proteome Discoverer. The search engine is capable to handle several linker types as well as data input formats. To demonstrate its ability processing Bruker -ion mobility data, synthetic peptides (Beveridge, et. al., Nat. Commun., 2020, doi: 10.1038/s41467-020-14608-2) were analyzed and the respective files are availible here.

Characteristics of senescent cells resistant to ABT263 and ARV825

Project description:ABT263 and ARV825 were identified as promising senolytic drugs based on our criteria. However, 20–30% of senescent cells survived treatment with these agents. To clarify why a subset of senescent cells remained resistant, we performed RNA-seq to characterize the surviving population. Several SASP factors were upregulated compared with untreated senescent cells, suggesting that incomplete senolysis may diminish therapeutic benefits and that more effective elimination of senescent cells is required. In addition, AKR1C1–3, which are involved in detoxifying reactive carbonyl species and reducing oxidative stress, were also upregulated. These results suggest that the surviving cells may overcome mitochondrial stress by preserving mitochondrial membrane potential and limiting ROS accumulation.

RNA sequencing analysis of ARV825 target genes in senescent cells

Project description:Although cellular senescence acts primarily as a tumor suppression mechanism, the accumulation of senescent cells in vivo eventually exerts deleterious side effects through inflammatory/tumor-promoting factor secretion. Thus, the development of new drugs that cause the specific elimination of senescent cells, termed senolysis, is anticipated. Here, by an unbiased high-throughput screening of chemical compounds and a bio-functional analysis, we identify ARV825 as a promising senolytic drug. ARV825 treatment eliminates senescent hepatic stellate cells in obese mouse livers, accompanied by the reduction of liver cancer development. Furthermore, the elimination of chemotherapy-induced senescent cells by ARV825 increases the efficacy of chemotherapy against xenograft tumors in immunocompromised mice. These results reveal the vulnerability of senescent cells and open up possibilities for its control.
