ProteomicsCarrier protein-enabled host cell proteome analysis (CP-HCP) with integrated isobaric tag interference filtering
We have created a CP-HCP method to characterise the carrier proteome of a host cell expression system producing recombinant protein biotherapeutic, which can be compared with the testing sample mixture containing trace amounts of host cell proteins against high-background recombinant protein and als...

ProteomicsA Triple Knockout (TKO) Proteomics Standard for Diagnosing Ion Interference in Isobaric Labeling Experiments
Isobaric labeling is a powerful strategy for quantitative mass spectrometry-based proteomic investigations. A complication of such analyses has been the co-isolation of multiple analytes of similar mass-to-charge resulting in the distortion of relative protein abundance measurements across samples. ...

Proteomics29-Plex Tandem Mass Tag Mass Spectrometry Enabling Accurate Quantification by Interference Correction
Tandem mass tag (TMT) mass spectrometry is a mainstream isobaric chemical labeling strategy for profiling proteomes. Here we present a 29-plex TMT method to combine the 11-plex and 18-plex labeling strategies. The 29-plex method was examined with a pooled sample composed of 1x, 3x and 10x E. coli pe...

TranscriptomicsCooler temperatures destabilize RNA interference and increase susceptibility of disease vector mosquitoes to viral infection
The impact of global climate change on the transmission dynamics of infectious diseases is the subject of extensive debate. The transmission of mosquito-borne viral diseases is particularly complex, with climatic variables directly affecting many parameters associated with the prevalence of disease ...

ProteomicsCarrier protein-enabled host cell proteome analysis (CP-HCP) with integrated isobaric tag interference filtering
We added increasing amounts of E coli carrier proteome to BSA, our moch recombinant protein to model interference of high-background BSA peaks with smaller peaks of E coli HCPs, using MS2 and MS3 methods to show co-fragmentation and co-elution based on similar m/z ratio. We created an interference d...

We used TMT labelling to set up different experiment channels containing mixtures of the host cell carrier proteome (E coli) and mock biotherapeutic (BSA), to compare with interference detection channel to model and filter interference, a phenomenon where host cell proteins (HCPs) co-elute with high...

TranscriptomicsProfiling of circadian genes expressed in the uterus endometrial stromal cells of pregnant rats as revealed by DNA microarray coupled with RNA interference
The peripheral circadian oscillator plays an essential role in synchronizing local physiology to operate in a circadian manner via regulation of the expression of clock-controlled genes. In the murine uterus, the endometrial stromal cells undergo proliferation and differentiation into decidual cells...

ProteomicsCarrier protein-enabled host cell proteome analysis (CP-HCP) with integrated isobaric tag interference filtering.
Here, we proposed that the use of an HCP carrier proteome could enhance the acquisition of spectra from HCPs amidst a highly abundance therapeutic protein background to perform global HCP analysis. We provide proof of principle of this approach, which we term carrier proteome-HCP (CP-HCP) analysis, ...

P granules are germ-cell-specific cytoplasmic structures containing RNA and protein and required for proper germ cell development in C. elegans. A new P-granule-associated protein, DEPS-1, whose loss disrupts P granule structure and function was analysed in this study. Genome wide analysis of gene...
