Abstract
The FASTK family of proteins have been recently reported to play a key role in the post-transcriptional regulation of mitochondrial gene expression, including mRNA stability and translation. Accumulated studies have provided evidence that the expression of some FASTK genes is altered in certain types of cancer, in agreement with the central role of mitochondria in cancer development. Here, we obtained a pan-cancer overview of the genomic and transcriptomic alterations of FASTK genes. FASTK, FASTKD1, FASTKD3 and FASTKD5 showed the highest rates of genetic alterations. FASTK and FASTKD3 alterations consisted mainly of amplifications that were seen in more than 8% of ovarian and lung cancers, respectively. FASTKD1 and FASTKD5 were the most frequently mutated FASTK genes, and the mutations were identified in 5-7% of uterine cancers, as well as in 4% of melanomas. Our results also showed that the mRNA levels of all FASTK members were strongly upregulated in esophageal, stomach, liver and lung cancers. Finally, the protein-protein interaction network for FASTK proteins uncovers the interaction of FASTK, FASTKD2, FASTKD4 and FASTKD5 with cancer signaling pathways. These results serve as a starting point for future research into the potential of the FASTK family members as diagnostic and therapeutic targets for certain types of cancer.

Genetic ablation of fas-activated serine/threonine kinase ameliorates alcoholic liver disease through modulating HuR-SIRT1 mRNA complex stability. Free Radic Biol Med 2021; 166:201-211.

Abstract
Chronic alcoholism often causes liver injuries characterized by hepatic steatosis, inflammation as well as oxidative stress and finally leads to advanced cirrhosis and liver cancer. Fas-activated serine/threonine kinase (FASTK) and its homologs are gradually known as multifunctional proteins involved in various biological processes; however, the role of FASTK and its family members in alcoholic liver disease (ALD) is still unexplored. Here we found that, among FASTK family members, the expression of FASTK was specifically induced both in livers of mice received chronic ethanol ingestion and in ethanol-stimulated hepatocytes. Animal studies showed that genetic deletion of FASTK attenuated chronic ethanol ingestion-induced liver damage, steatosis, and inflammation. Moreover, FASTK deficiency was associated with improved oxidative/anti-oxidative system homeostasis and reduced reactive oxygen species (ROS) generation in livers upon chronic ethanol stimulation. Importantly, FASTK ablation preserved hepatic sirtuin-1 (SIRT1) expression/activity upon chronic ethanol ingestion and SIRT1 silencing via adenovirus-mediated small interfering RNA transfer diminished FASTK deletion-elicited beneficial effects on alcohol-associated hepatic steatosis, inflammation, and oxidative stress. Mechanistically, ethanol increased the phosphorylation of human antigen R (HuR, a RNA binding protein that stabilizes SIRT1 mRNA) and triggered the dissociation of HuR-SIRT1 mRNA complex, in turn promoting SIRT1 mRNA decay. Genetic deletion of FASTK diminished ethanol-induced HuR phosphorylation and HuR-SIRT1 mRNA complex dissociation, thereby enhancing SIRT1 mRNA stability. Collectively, these findings for the first time highlight a critical role of FASTK in the pathogenesis of ALD and implicate HuR-SIRT1 mRNA complex involves in this process.

The Mitochondrial Isoform of FASTK Modulates Nonopsonic Phagocytosis of Bacteria by Macrophages via Regulation of Respiratory Complex I. THE JOURNAL OF IMMUNOLOGY 2018; 201:2977-2985. [PMID: 30322967 DOI: 10.4049/jimmunol.1701075] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Subscribe] [Scholar Register] [Received: 07/25/2017] [Accepted: 09/10/2018] [Indexed: 12/18/2022]
Abstract
Phagocytosis is a pivotal process by which innate immune cells eliminate bacteria. In this study, we explore novel regulatory mechanisms of phagocytosis driven by the mitochondria. Fas-activated serine/threonine kinase (FASTK) is an RNA-binding protein with two isoforms, one localized to the mitochondria (mitoFASTK) and the other isoform to cytosol and nucleus. The mitoFASTK isoform has been reported to be necessary for the biogenesis of the mitochondrial ND6 mRNA, which encodes an essential subunit of mitochondrial respiratory complex I (CI, NADH:ubiquinone oxidoreductase). This study investigates the role and the mechanisms of action of FASTK in phagocytosis. Macrophages from FASTK─/─ mice exhibited a marked increase in nonopsonic phagocytosis of bacteria. As expected, CI activity was specifically reduced by almost 50% in those cells. To explore if decreased CI activity could underlie the phagocytic phenotype, we tested the effect of CI inhibition on phagocytosis. Indeed, treatment with CI inhibitor rotenone or short hairpin RNAs against two CI subunits (NDUFS3 and NDUFS4) resulted in a marked increase in nonopsonic phagocytosis of bacteria. Importantly, re-expression of mitoFASTK in FASTK-depleted macrophages was sufficient to rescue the phagocytic phenotype. In addition, we also report that the decrease in CI activity in FASTK─/─ macrophages is associated with an increase in phosphorylation of the energy sensor AMP-activated protein kinase (AMPK) and that its inhibition using Compound C reverted the phagocytosis phenotype. Taken together, our results clearly demonstrate for the first time, to our knowledge, that mitoFASTK plays a negative regulatory role on nonopsonic phagocytosis of bacteria in macrophages through its action on CI activity.
