Project description:Poly(ADP-ribose) polymerases (PARPs) modify target proteins with ADP-ribose by using nicotinamide adenine dinucleotide as a substrate, and contribute to various signaling pathways. PARP14 is the largest member of PARP superfamily. Whole RNA-sequencing analysis was performed and analyzed by Lc. Biotech Co., Ltd. (Hangzhou, China). Primary mouse microglia from the Con + ACT-Con group, Con + ACT-PARP14 group, OGD + ACT-Con group, and OGD + ACT-Con group were collected in TRIzol. Total RNAs were extracted from Trizol. UMI technology was used to label each sequence fragment with sequence tags, which minimized the interference of duplication caused by PCR amplification on the quantitative accuracy of the transcriptome. RNA sequencing reads were aligned to the mouse genome (GRCh37/hg19) using the software Hisat2 (2.0.4). Transcript abundance was evaluated by calculating fragments per kilo base of exon per million fragments mapped (FPKM).

Project description:While immune checkpoint blockade therapy (ICBT) benefits cancer patients, many fail to maintain their response due to adaptive resistance mechanisms. IFNγ is critical for cellular immunity, but also promotes adaptive resistance to ICBT. We have established a role for PARP14 in mediating IFNγ-induced adaptive resistance. We confirm that chronic pre-treatment of tumour cells with IFNγ confers resistance to α-PD-1 antibodies in syngeneic mouse tumour models. We identified that PARP14 was consistently upregulated in cancer cells treated chronically with IFNγ as well as in IFNγ-high melanoma samples. Further, we showed that PARP14 knockdown or pharmacological inhibition restores sensitivity to α-PD-1 antibodies accompanied by increased immune cell infiltration into tumours but the decreased presence of regulatory T cells. RNA sequencing analysis of tumours and cultured cells treated with PARP14 inhibitor showed an upregulation of inflammatory-related pathways. In conclusion, PARP14 is an actionable target for reversing IFNγ-driven adaptive resistance to ICBT.

Project description:The variable clinical course of follicular lymphoma (FL) is determined by the molecular heterogeneity of tumor cells and complex interactions within the tumor microenvironment (TME). IL-4 producing follicular helper T cells (TFH) are critical components of the FL TME. Binding of IL-4 to IL-4R on FL cells activates JAK/STAT signaling. We identified STAT6 mutations (STAT6MUT) in 13% of FL (N = 33/258), all clustered within the DNA binding domain. Gene expression data and immunohistochemistry showed upregulation of IL-4/STAT6 target genes in STAT6MUT FL, including CCL17, CCL22, and FCER2 (CD23). Functionally, STAT6MUT was gain-of-function by serial replating phenotype in pre-B CFU assays. Expression of STAT6MUT enhanced IL-4 induced FCER2/CD23, CCL17 and CCL22 expression and was associated with nuclear accumulation of pSTAT6. RNA sequencing identified PARP14 -a transcriptional switch and co-activator of STAT6- among the top differentially upregulated genes in IL-4 stimulated STAT6MUT lymphoma cells and in STAT6MUT primary FL cells. Quantitative chromatin immunoprecipitation (qChIP) demonstrated binding of STAT6MUT but not STAT6WT to the PARP14 promotor. Reporter assays showed increased IL-4 induced transactivation activity of STAT6MUT at the PARP14 promotor, suggesting a self-reinforcing regulatory circuit. Knock-down of PARP14 or PARP-inhibition abrogated the STAT6MUT gain-of-function phenotype. Thus, our results identify PARP14 as a novel therapeutic target in STAT6MUT FL.

Project description:PARP14 is a mono-ADP-ribosyl transferase involved in the control of immunity, transcription and DNA replication stress management. However, little is known about the ADP-ribosylation activity of PARP14, including its substrate specificity or how PARP14-dependent ADP-ribosylation is reversed. Here we show that PARP14 is dual function enzyme with both ADP-ribosyl transferase and hydrolase activity acting on both protein and nucleic acid substrates. In particular, we show that the PARP14 macrodomain 1 is an active ADP-ribosyl hydrolase. We also demonstrate hydrolytic activity for the first macrodomain of PARP9. We reveal that expression of a PARP14 mutant with the inactivated macrodomain 1 results in a dramatic increase in mono(ADP-ribosyl)ation of proteins in human cells, including PARP14 itself and antiviral PARP13. Moreover, we demonstrate that the closely related hydrolytically active macrodomain of SARS2 Nsp3, Mac1, efficiently reverses PARP14 ADP-ribosylation in vitro and in cells, supporting the evolution of viral macrodomains to counteract PARP14-mediated antiviral response.

Project description:The enzymes of the poly-ADP-ribose polymerase (PARP) super-family control many relevant cellular processes, but a precise understanding of their activities in different physiological or disease contexts is largely incomplete. We found that transcription of several PARP genes was dynamically regulated upon macrophage activation by several inflammatory stimuli. Specifically, PARP14 was strongly induced by endotoxin stimulation and translocated to the nucleus in stimulated cells. Quantitative mass spectrometry analysis showed that PARP14 bound to a group of interferon-stimulated gene (ISG)-encoded proteins, most with an unknown function, and it was required for their nuclear accumulation. Moreover, PARP14 depletion attenuated transcription of primary antiviral response genes regulated by the transcription factor IRF3, including Ifnb1, thus reducing IFNβ production and activation of ISGs involved in the secondary antiviral response. Overall, these data hint at a role of PARP14 in the control of antimicrobial responses and specifically in nuclear activities of a subgroup of ISG-encoded proteins.
