Our laboratory has been concerned with the structure and function of the decapentaplegic gene complex (DPP-C) in Drosophila melanogaster. To define the boundaries of the complex, we have studied the genetics of mutations allelic to a previously discovered mutation shortvein (shv), known to reside near decapentaplegic. We found that shortvein resides distal to Hin-d and dpp within the same polyt...

The level of dipeptidyl peptidase-4 (DPP-4) of children with type 1 diabetes mellitus (T1DM) was observed to evaluate the improvement in function of the nutritional intervention. In total, 132 children with T1DM (T1DM group) and 132 healthy children (NC group) based on physical examination admitted to our hospital from September 2014 to June 2015 and were studied. General data of the two groups...

background: date palm pollen (dpp) and astragalus genus are used in some countries for the treatment of infertility. objective: this study was designed to investigate effects of dpp and astragalus ovinus (a.ovinus) on fertility in healthy adult male rats. materials and methods: thirty-six rats were divided into six groups (n=6) including control and five treatment groups. dpp (120, 240 and 360 ...

A series of triazole based uracil derivatives were designed and synthesized as novel DPP-4 inhibitors. Compound A01 was identified as a lead compound for SAR studies focused on the structural modification at the S2' subsite of DPP-4. The novel analogues A02-A25 were obtained by modifying the substituents at the phenyl group, and B01-B09, by introducing the carbonyl group. On screening in DPP-4,...

Early detection of leptospirosis with field-ready diagnostics may improve clinical management and mitigate outbreaks. We previously validated the point-of-care Dual Path Platform (DPP) for leptospirosis with sera in the laboratory. This prospective study compares the diagnostic accuracy and clinical utility of the DPP using finger stick blood (FSB) against the serum DPP, venous whole blood (VWB...

objective: druggability of a target protein depends on the interacting micro-environment between the target protein and drugs. therefore, a precise knowledge of the interacting micro-environment between the target protein and drugs is requisite for drug discovery process. to understand such micro-environment, we performed in silico interaction analysis between a human target protein, dipeptidyl...

Dentin phosphophoryn (DPP) is a dentin sialophosphoprotein gene product that has an RGD motif and repeat sequences of aspartic acid and phosphoserine. To date, the function of DPP in the early stage of reparative dentin formation still remains unclear. The objective of this study was to evaluate the effects of DPP on pulp cell migration and proliferation. DPP promoted cell migration in a concen...

The decapentaplegic (dpp) gene directs numerous developmental events in Drosophila melanogaster. dpp encodes a member of the Transforming Growth Factor-beta family of secreted signaling molecules. At this time, mechanisms of dpp signaling have not yet been fully described. Therefore we conducted a genetic screen for new dpp signaling pathway components. The screen exploited a transvection-depen...

In Drosophila, the imaginal discs are the primordia for adult appendages. Their proper formation is dependent upon the activation of the decapentaplegic (dpp) gene in a stripe of cells just anterior to the compartment boundary. In imaginal discs, the dpp gene has been shown to be activated by Hedgehog signal transduction. However, an initial analysis of its enhancer region suggests that its reg...

decapentaplegic (dpp) is a Transforming Growth Factor beta (TGF-beta)-related growth factor that controls multiple developmental processes in Drosophila. To identify components involved in dpp signaling, we carried out a genetic screen for dominant enhancer mutations of a hypomorphic allele of thick veins (tkv), a type I receptor for dpp. We recovered new alleles of tkv, punt, Mothers against d...
