plexDIA: sensitive proteomics with simultaneous deep coverage, high throughput, low missing data.

plexDIA: sensitive proteomics with simultaneous deep coverage, high throughput, low missing data.

Although current mass-spectrometry (MS) methods can separately achieve deep proteome coverage, low missing data, high throughput, or high sensitivity, simultaneous combination of these has remained challenging. Here Derks et al. …

CDK4/6 inhibitors: critical regulation of T-cell memory fate commitment in tumour microenvironment.

CDK4/6 inhibitors: critical regulation of T-cell memory fate commitment in tumour microenvironment.

Pharmacologic inhibitors of cyclin-dependent kinases 4 and 6 (CDK4/6) have well-defined tumour-intrinsic cytostatic mechanisms. They are an approved treatment for hormone receptor–positive breast cancer and currently under evaluation in numerous …

On chip: multiplexed low input TMT-labelled quantitative proteomics with digital microfluidics.

On chip: multiplexed low input TMT-labelled quantitative proteomics with digital microfluidics.

Digital microfluidics (DMF) technology facilitates miniaturised, automated, multiplexed liquid handling in multiple bioanalytical applications. However, in LC-MS-based proteomics its use has been limited to qualitative analysis, where the compatibility with …

‘Til death do us part: conformational change for MLKL, disengagement from RIPK3 in necroptosis.

‘Til death do us part: conformational change for MLKL, disengagement from RIPK3 in necroptosis.

Necroptosis is a lytic form of programmed cell death that is dysregulated in multiple human pathologies. Originating as a host defence mechanism against invading pathogens, necroptosis is triggered by various …

PP2A, CDK9 transcription checkpoint interplay? Check! Targetable tumorigenesis inhibitor? Check!

PP2A, CDK9 transcription checkpoint interplay? Check! Targetable tumorigenesis inhibitor? Check!

RNA polymerase II (RNAPII)-driven transcription is a highly conserved process with distinct checkpoints, each controlled by dedicated transcriptional cyclin-dependent kinases (CDKs). CDK9 controls the pause-release checkpoint following transcription initiation. CDK …

Cell surface proteomics reveals major new targets for regulation by MARCH proteins.

Cell surface proteomics reveals major new targets for regulation by MARCH proteins.

MARCH proteins are membrane-associated Ring-CH E3 ubiquitin ligases that ubiquitinate and regulate cell surface expression of major histocompatibility complexes I and II as well as T- and B-cell co-activation receptors, …

The truth about aging; proteomic characterisation of young and old mouse hematopoietic stem and progenitor cells.

The truth about aging; proteomic characterisation of young and old mouse hematopoietic stem and progenitor cells.

Haematopoietic stem cells (HSCs) are responsible for continuous renewal of blood and immune cells, capable of both self-renewal and differentiation into effector cells. The balance of these processes is critical …
