ProteomicsComplementary peptides (cPEPs) modulate protein translation
MicroRNAs (miRNAs) are small regulatory RNAs that control plant and animal development by regulating post-transcriptional gene expression. Primary transcripts of miRNAs contain small ORFs that can be translated into small peptides (miPEPs). MiPEPs specifically enhance the expression of their cognate...

ProteomicsTMTPro Complementary Ion Quantification Increase Plexing and Sensitivity for Accurate Multiplexed Proteomics at the MS2 level
The ability of the TMTPro isobaric labeling reagents to form complementary ions for accurate multiplexed proteomics at the MS2 level was investigated. Human and yeast peptides were labeled in distinct ratios to analyze the effect of interference on the quantification accuracy. A method, TMTProC, was...

ProteomicsEnzyme and Chemical Assisted N-Terminal Blocked Peptides Analysis, ENCHANT, as a Selective Proteomics Approach Complementary to Conventional Shotgun Approach
Shotgun (bottom-up) approach has been widely applied in large-scale proteomics studies. The inherent shortages of shotgun approach lie in that the generated peptides often overwhelm the analytical capacity of current LC-MS/MS systems and that abundant proteins often hamper the identification of prot...

TranscriptomicsTranscription profiling by array of E. coli NCTC 9001 challenged with four different cationic antimicrobial peptides
Obtaining an in depth understanding of the arms races between peptides comprising the innate immune response and bacterial pathogens is of fundamental interest and will inform the development of new antibacterial therapeutics. Many cationic antimicrobial peptides (AMPs) share a range of structural a...

TranscriptomicsEffect of phenylalanine-rich peptide on growth and survival of Mycobacterium tuberculosis H37Rv (Mtb)
During our efforts to isolate potantial binding partners of Esat6, we isolated few peptides rich in phenylalanine residues that strongly interacted with Esat6. All peptides were less than fifty amino acids in length, One of them, Hcl1, when expressed in mycobacteria showed significant retardation in...

ProteomicsProteomics of treatment of Arabidopsis thaliana with peptides
Plants were treated with a cPEP for luciferase (PEP Luc) or a scrambled version of this peptide (4 biological replicates each). Leaves were snap frozen in liquid nitrogen and grounded into powder. The powder was resuspended in tris 50 mM and 5% SDS, sonicated and centrifuged at 14,000 g for 10 min. ...
