Introduction

NADPH-dependent oxidoreductase which catalyzes the reduction of dicarbonyl compounds. Displays reductase activity in vitro with 3,4-hexanedione, 2,3-heptanedione and 1-phenyl-1,2-propanedione as substrates (PubMed:16685466). May function as a dicarbonyl reductase in the enzymatic inactivation of reactive carbonyls involved in covalent modification of cellular components (PubMed:16685466). Also displays a minor hydroxysteroid dehydrogenase activity toward bile acids such as ursodeoxycholic acid (UDCA) and isoursodeoxycholic acid (isoUDCA), which makes it unlikely to control hormone levels (PubMed:16685466). Doesn't show any activity in vitro with retinoids and sugars as substrates (PubMed:16685466). Attenuates MDM2-mediated p53/TP53 degradation, leading to p53/TP53 stabilization and increased transcription activity, resulting in the accumulation of MDM2 and CDKN1A/p21 (PubMed:20547751). Reduces proliferation, migration and invasion of cancer cells and well as the production of ROS in cancer (PubMed:29106393).

AIMSVascular and endothelial aging are significant causes of chronic diseases among the elderly. This study investigated the specific mechanism by which sirtuin 3 (SIRT3) regulates vascular endothelial senescence and the beneficial role of Bazi Bushen capsule (BZBS) in preventing vascular aging.METHODSHuman umbilical vein endothelial cells and mouse aortic endothelial cells were cultured with D-galactose (D-gal) to induce aging and evaluate the beneficial effects of the SIRT3-dehydrogenase/reductase member 2 (DHRS2) axis on the inhibition of vascular endothelial aging. d-Gal was injected intraperitoneally into wild-type and Sirt3 knockout mice, while BZBS was administered orally. Histochemical staining, immunohistochemistry, and western blotting assays were used to explore the beneficial effects of BZBS against aging-associated vascular remodelling. Endothelial cell function assays were used to evaluate the role of BZBS in suppressing endothelial aging in vitro.RESULTSSIRT3 deacetylated DHRS2 and modulated the translation of DHRS2. The SIRT3-DHRS2 axis played an important role in preserving mitochondrial homeostasis and reducing reactive oxygen species generation through suppressing endothelial nitric oxide synthase (eNOS) translocating to mitochondria and eNOS-Thr495 phosphorylation mediated by protein kinase C δ (PKCδ). BZBS mitigated vascular remodelling and relieved endothelial oxidative stress via the SIRT3-DHRS2 axis.CONCLUSIONSIRT3 activates DHRS2-PKCδ to stop aging in endothelial cells by inhibiting uncoupled eNOS translocating to mitochondria. BZBS rescued vascular aging and endothelial dysfunction via the SIRT3-DHRS2 axis. Revealing a protective mechanism by which SIRT3 inhibits endothelial senescence, this study provides evidence for BZBS in delaying vascular aging.

Ectopic protein lysine methacrylation contributes to defects caused by loss of HIBCH or ECHS1

Article

Author: Wang, Junling ; Zhou, Caixia ; Xu, Chaolong ; Shang, Weina ; Tong, Chao ; Wang, Liquan ; Li, Zhirong ; Yang, Bing ; Liu, Yang ; Fang, Fang ; Liu, Zhimei ; Wu, Ting ; Li, Yaoyao ; Li, Yawen

The absence of HIBCH or ECHS1, two Leigh syndrome genes, in cultured cells results in abnormal mitochondrial morphology and respiratory defects. Fly eyes lacking either protein exhibit age-dependent degeneration. Elevated lysine methacrylation (Kmea) is observed in both HIBCH- and ECHS1-deficient cells and fly tissues. Quantitative mass spectrometry reveals that many proteins are ectopically modified by Kmea in these cells. Mimicking Kmea in proteins like CH60, FKBP4, BIP, LDHB, or DHRS2 replicates the mitochondrial morphology changes seen in HIBCH- or ECHS1-deficient cells. Reducing Kmea modification partially rescues mitochondrial morphology changes in cells and eye degeneration in flies. Fibroblasts from patients with HIBCH or ECHS1 mutations show similar mitochondrial changes and elevated Kmea, which are significantly reversed by administering N-acetyl-L-cysteine to reduce Kmea levels. We propose that ectopic Kmea modification mediates the defects caused by HIBCH- or ECHS1-deficiency. Reducing Kmea modification provides a new approach for treating HIBCH- or ECHS1-related Leigh syndrome.

BACKGROUNDDeregulation of lipid metabolism is one of the most prominent metabolic features in cancer. The activation of sphingolipid metabolic pathways affects the proliferation, invasion, angiogenesis, chemoresistance, and immune escape of tumors, including colorectal cancer (CRC). Dehydrogenase/reductase member 2 (DHRS2), which belongs to the short-chain dehydrogenase/reductase (SDR) family, has been reported to participate in the regulation of lipid metabolism and impact on cancer progression. Trichothecin (TCN) is a sesquiterpenoid metabolite originating from an endophytic fungus of the herbal plant Maytenus hookeri Loes. Studies have shown that TCN exerts a broad-spectrum antitumor activity.METHODSWe evaluated the proliferative ability of CRC cells by CCK8 and colony formation assays. A metabolite profiling using liquid chromatography coupled with mass spectrometry (LC/MS) was adopted to identify the proximal metabolite changes linked to DHRS2 overexpression. RNA stability assay and RNA immunoprecipitation (RIP) experiments were applied to determine the post-transcriptional regulation of SPHK1 expression by DHRS2. We used flow cytometry to detect changes in cell cycle and cell apoptosis of CRC cells in the absence or presence of TCN.RESULTSWe demonstrate that DHRS2 hampers the sphingosine kinases 1 (SPHK1)/sphingosine 1-phosphate (S1P) metabolic pathway to inhibit CRC cell growth. DHRS2 directly binds to SPHK1 mRNA to accelerate its degradation in a post-transcriptionally regulatory manner. Moreover, we illustrate that SPHK1 downregulation induced by DHRS2 contributes to TCN-induced growth inhibition of CRC.CONCLUSIONSThe present study provides a mechanistic connection among metabolic enzymes, metabolites, and the malignant progression of CRC. Moreover, TCN could be developed as a potential pharmacological tool against CRC by the induction of DHRS2 and targeting SPHK1/S1P metabolic pathway.
