Effect of 20-Hete and dietary restriction on murine kidneys

Project description:Transcriptomic dataset of 15 murine kidneys of 14-week-old male C57Bl6 mice. Mice were divided into 3 treatment groups four weeks prior to nephrectomy and 5 mice had ad libitum (AL) access to food and water, while another 10 mice received 30% food restriction (CR). Calorically restricted mice either received intraperitoneal supplementation of 20-HETE (HETE) or vehicle (Veh, EtOH in sodiumchloride 0.9%) for 8 days on a daily basis prior to nephrectomy. Ad libitum fed mice received vehicle injections for 8 days on a daily basis prior to nephrectomy.

Effects of Irg1-itaconate or Hemin on gene expression in macrophages [RNA-seq]

Project description:To investigate the role of Irg1-itaconate or Hemin in macrophages, bone marrow-derived macrophages (BMDMs) from WT mice and Irg1 KO mice were extracted and cultured. After 7 days of cells culture, the BMDMs from WT mice were treated 120 μM 4-octyl itaconate (4-OI) for 15 h, 15 μM Hemin for 12 h, and the BMDMs from Irg1 KO mice and WT mice were treated Vehicle for 12 h. We then performed gene expression profiling analysis using data obtained from RNA-seq of 4-OI, Hemin or vehicle treated WT BMDMs and Irg1 KO BMDMs.

Pla2g7 regulates bone homeostasis via Alox12/12-HETE/Gpr31 signaling axis

Project description:<p>Bone homeostasis mainly depends on the equilibrium of osteoclasts and osteoblasts, overactivated osteoclasts play a pivotal role in the progression of osteoporosis. Here, we revealed that Pla2g7 (phospholipase A2 group VII) was positively correlated with bone resorption in clinic. By single-cell RNA-seq data analysis, Pla2g7 was found highly enriched in osteoclasts along the developmental trajectory, which promoted osteoclast differentiation. Inhibition of Pla2g7 by Darapladib impaired both human and mice osteoclast differentiation, meanwhile, Pla2g7-deficient mice showed higher bone mass and restored the ovariectomy-induced bone loss. Mechanistically, we identified that Alox12 (arachidonate 12-lipoxygenase) mediated-arachidonic acid metabolism is a key determinant in Pla2g7 enhanced osteoclast differentiation. Its metabolite 12-HETE (12-hydroxyeicosatetraenoic acid) activated Gpr31 to regulate osteoclast formation via p38 MAPK pathway and mitochondrial energy metabolism. Collectively, our study uncovers an Alox12/12-HETE/Gpr31 axis that regulates Pla2g7-induced osteoclast differentiation, and provides a new insight for osteoporosis treatment.</p>

Identification of Or5v1/Olfr110 as an oxylipin receptor and anti-obesity target

Project description:For the phosphoproteomics study, hepatocytes isolated from WT and Olfr110-/- mice were serum-starved and stimulated with 1 μM 12(S)-HEPE or control vehicle for 10 min, washed with ice-cold PBS and lysed using 8M urea containing phosphatase and protease inhibitors.

A hypermethylated ALOX12 gene is highly susceptible to 5-azacytidine treatment in myelodysplastic syndromes

Project description:5-azacytidine (AZA) is widely used for treatment of myelodysplastic syndromes (MDS). However, identifying predictive factors for response to AZA remains challenging. The aim in present study was to identify the genes which are susceptible to AZA in MDS and investigate the possibility of the gene for predictor for response to AZA therapy. To identify AZA-susceptible genes, we compared the gene expression changes by AZA in MDS-L cells (AZA-sensitive) with those in MDS-L/CDA cells (AZA-resistant) in culture. Of 438 AZA-susceptible genes, we searched the genes which are hypermethylated in MDS patients as compared to healthy controls by analyzing public dataset GSE152710, and found ALOX12 gene. Analysis of public dataset GSE145733 and GSE58831 revealed that ALOX12 expression was suppressed in MDS classes with excess blasts but not in other classes, and were negatively and positively correlated with bone marrow blast counts and survival, respectively, in MDS patients. Analysis of public dataset GSE152710 revealed that the methylation level of ALOX12 gene was decreased in MDS patients with complete remission but not in those with partial response and progression disease after AZA therapy. Our retrospective clinical study in which nine AZA-treated patients were enrolled suggested that ALOX12 expression was increased in patients with favorable response, while decreased in patient with poor response after AZA therapy. In conclusion, ALOX12 gene could be tumor suppressive and promising marker for predicting the response to AZA therapy in MDS.
