Neuropeptides PDF and DH31 hierarchically regulate free-running rhythmicity in Drosophila circadian locomotor activity.
Goda T, Umezaki Y, Alwattari F, Seo HW, Hamada FN. Goda T, et al. Sci Rep. 2019 Jan 29;9(1):838. doi: 10.1038/s41598-018-37107-3. Sci Rep. 2019. PMID: 30696873 Free PMC article.
We determined that Dh31 loss-of-function mutants (Dh31(#51)) showed normal rhythmicity, whereas Dh31(#51);Pdf(01) double mutants exhibited a severe arrhythmic phenotype compared to Pdf-null mutants (Pdf(01)). The expression of tethered-PDF or tethered- …

Novel peptidomimetic peptide deformylase (PDF) inhibitors of Mycobacterium tuberculosis.
Gokhale KM, Telvekar VN. Gokhale KM, et al. Chem Biol Drug Des. 2021 Jan;97(1):148-156. doi: 10.1111/cbdd.13769. Epub 2020 Aug 24. Chem Biol Drug Des. 2021. PMID: 32745362
In order to explore, identify and develop new anti-tubercular drugs, novel peptidomimetic series of Mtb-peptide deformylase (PDF) inhibitors was designed and synthesized. In vitro antimycobacterial potential of compounds was established by screening of compounds against My …

PDF and cAMP enhance PER stability in Drosophila clock neurons.
Li Y, Guo F, Shen J, Rosbash M. Li Y, et al. Proc Natl Acad Sci U S A. 2014 Apr 1;111(13):E1284-90. doi: 10.1073/pnas.1402562111. Epub 2014 Mar 18. Proc Natl Acad Sci U S A. 2014. PMID: 24707054 Free PMC article.
The neuropeptide PDF is important for Drosophila circadian rhythms: pdf(01) (pdf-null) animals are mostly arrhythmic or short period in constant darkness and have an advanced activity peak in light-dark conditions. ...PDF is known to increase cAMP leve …

PDF receptor signaling in Caenorhabditis elegans modulates locomotion and egg-laying.
Meelkop E, Temmerman L, Janssen T, Suetens N, Beets I, Van Rompay L, Shanmugam N, Husson SJ, Schoofs L. Meelkop E, et al. Mol Cell Endocrinol. 2012 Sep 25;361(1-2):232-40. doi: 10.1016/j.mce.2012.05.001. Epub 2012 May 11. Mol Cell Endocrinol. 2012. PMID: 22579613
We demonstrate that the pdfr-1 mutant phenocopies the defective locomotor behavior of the pdf-1 mutant and that pdf-1 and pdf-2 behave antagonistically. All three PDF receptor splice variants are involved in the regulation of locomotor behavior. ...We …

PDF text classification to leverage information extraction from publication reports.
Bui DD, Del Fiol G, Jonnalagadda S. Bui DD, et al. J Biomed Inform. 2016 Jun;61:141-8. doi: 10.1016/j.jbi.2016.03.026. Epub 2016 Apr 1. J Biomed Inform. 2016. PMID: 27044929 Free PMC article.
Our goal is to categorize PDF texts for strategic use by IE systems. METHODS: We used an open-source tool to extract raw texts from a PDF document and developed a text classification algorithm that follows a multi-pass sieve framework to automatically classify PD
