Project description:Deglycosylated-leucine-rich α-2-glycoprotein1 (DG-LRG1) as well as LRG1 was discovered to promote angiogenesis under diabetes mellitus condition through TGF-β independent binding to endoglin. To examine the signaling pathways triggered by DG-LRG1, we subjected whole-cell protein lysates of control and DG-LRG1 treated HUVECs to a Phospho Explorer antibody array analysis using commercial antibody array assay kit (Full Moon Biosystems, Inc.). Samples were probed against 1318 site-specific and phospho-specific antibodies with two replicates per antibody printed on a coated glass microscope slide. Phospho Explorer antibody array experiments and analyses were performed as a custom service by E-Biogen (Ebiogen Inc., Seoul, Republic of Korea).
Project description:β-cell specific IFT88 knock-out mice recapitulate human diabetes with impaired insulin secretion and altered islet hormone paracrine regulation. To examine the signaling pathways regulating islet cell function, we subjected protein lysates of whole islets from control and IFT88 knockout mice to a commercial phospho-antibody array analysis (Full Moon Bio, Inc). Samples were probed against 1318 site-specific and phospho-specific antibodies with 2 replicates per antibody on 76 x 25 x 1mm glass slides.
Project description:To identify differentially phosphorylated proteins between wild-type and Pak1-deficient mouse breast cancer cells, we performed a comparative study by using phospho-antibody arrays.
Project description:To investigate the effect of LRG1 overexpression on gene expression of eWAT from db/db mice, we transduced 4-week-old db/db mice with AAV8-eGFP or AAV8-LRG1-FL and harvested eWAT at 7 weeks and 10 weeks of age. We then performed gene expression profiling analysis using data obtained from RNA-seq of eWAT from eGFP- and LRG1-overexpressing mice at two time points.
Project description:To comprehensively analyze the effects of mTORC1 inhibition on GSK3, we employed the use of a PI3K/mTOR-specific phospho-antibody microarray that analyzed the site-specific phosphorylation of over 130 kinases within the PI3K/mTOR pathway. The phosphorylation levels of different kinases in monocytes were measured when stimulated with LPS in the presence or absence of a kind of mTORC1 inhibitor, rapamycin More than 130 highly specific and characterized phospho-antibodies for the human mTOR signaling pathway were immobilized and replicated six times on glass slides. The same non-phosphorylated target antibodies were included to allow the determination of the relative level of phosphorylatioin
Project description:Leucine-rich-alpha-2-glycoprotein1 (LRG1), a highly conserved member of the leucine-rich repeat family of proteins, has been reported to be involved in several tumors. Previous studies showed that it has great importance in epithelial–mesenchymal transition in colorectal cancer and could promote glioma cell lines invasion and migration. Despite the intimate relationships between LRG1 and migration in cancer research, its role in wound repair or re-epithelialization has not been uncovered. So we dicided using keratinocytes to see its transcriptomes changing after LRG1 addition.
Project description:In this project, we aimed to explore the role of extracellular vesicles (EVs) in Zika virus (ZIKV) infection. We preferred antibody capture to ltracentrifugation for exosome isolation. The EVs derived from naive HUVEc cells or ZIKV-infected HUVEc cells were harvested and analyzed by mass spectrometry. The protein profile data understand the relationship between the ZIKV and EVs.
Project description:β-cell specific Mettl14 knock-out mice display reduced N6-methyladenosine (m6A) levels and recapitulate human Type II diabetes (T2D) islet phenotype with early diabetes onset and mortality secondary to decreased β-cell proliferation and insulin degranulation. To gain insights into the role of m6A in regulating the IGF1/insulin -> AKT - > PDX1 pathway and to dissect the signaling networks modulating AKT phosphorylation, we subjected freshly isolated islets from control and Mettl14 knock-out mice to phospho-antibody microarrays.
Project description:scRNA-seq analysis confirmed that increased LRG1 is limited to GECs in early diabetic kidneys. As anticipated, LRG1 loss significantly attenuated diabetic glomerulopathy including podocyte loss, and improved renal function. scRNA-seq analysis demonstrated that LRG1 loss was sufficient to reverse all significant molecular pathway changes in diabetic mouse GECs, which were also associated with the dampening of TGF-β-induced gene expression. Moreover, LRG1 loss also led to a significant attenuation of TGF-β-mediated gene expression in podocytes and mesangial cells of diabetic mice. These results indicate that increased LRG1 directly potentiates TGF-β signaling in glomerular cells in an autocrine and paracrine manner to promote DKD, and indirectly via glomerular cross-talk.
Project description:transcription profiles of two groups each containing 5 strains of Disseminated gonorrhoeae (DG) and Undisseminated (superficial) gonorrhoeae (UG) were compared. An additional set of comparisons was done between 4 strains from group one Disseminated gonorrhoeae (DG) and another 4 strains from the same group.
