ProteomicsIdentification of phosphatases that dephosphorylate Tom6 using synthetic trap-peptides
The identification of phosphatases that dephosphorylate specific sites in proteins remains a major challenge, particularly for the major class of serine/threonine-specific phosphatases, which function as holoenzymes. Here, we report the development of synthetic trap-peptides to identify phosphatases...

ProteomicsTrapping efficiency of peptides on particle-packed and micro-pillar trap columns for proteomics analyses
In current work, we compared the separation of HeLa samples using two different trap columns for sample trapping, desalting, and preconcentration. The two columns have different types of the C18 stationary phase: a) a conventional packed PepMap C18 trap-column (Thermo Fischer Scientific), and b) the...

MetabolomicsMulti-omic Molecular Characterization and Diagnostic Biomarkers for Occult Hepatitis B Infection and HBsAg-Positive Hepatitis B Infection

BACKGROUND: The pathological and physiological characteristics between HBsAg-positive HBV infection and occult hepatitis B infection (OBI) are currently unclear. This study aimed to explore the immune microenvironment in the peripheral circulation of OBI patients through integration of proteomic ...

TranscriptomicsExpression profiling of hemocytes from Anopheles gambiae after malaria parasite infection
Insect hemocytes mediate important cellular immune responses including phagocytosis and encapsulation, and also secrete immune factors such as opsonins, melanization factors, and antimicrobial peptides. In Anopheles, they contribute to the defense against malaria parasite invasion during the early s...
