Spatiotemporal and quantitative analyses of phosphoinositides – fluorescent probe—and mass spectrometry‐based approaches

FEBS Letters, EarlyView.
Fluorescent probes allow dynamic visualization of phosphoinositides in living cells (left), whereas mass spectrometry provides high‐sensitivity, isomer‐resolved quantitation (right). Their synergistic use captures complementary aspects of lipid signaling. This review illustrates how these approaches reveal the spatiotemporal regulation and quantitative

Phosphatidylinositol 4‐kinase as a target of pathogens—friend or foe?

FEBS Letters, EarlyView.
This graphical summary illustrates the roles of phosphatidylinositol 4‐kinases (PI4Ks). PI4Ks regulate key cellular processes and can be hijacked by pathogens, such as viruses, bacteria and parasites, to support their intracellular replication. Their dual role as essential host enzymes and pathogen cofactors makes them promising drug targets.

Associating GWAS Information with the Notch Signaling Pathway Using Transcription Profiling

, 2011
Genome-wide association studies (GWAS) have identified SNPs associated with breast cancer. However, they offer limited insights about the biological mechanisms by which SNPs confer risk.

Regulation of the mTOR/S6K pathway by cellular energy [PDF]

, 2009
The mammalian target of rapamycin (mTOR) signaling pathway integrates positive and negative signals that control cellular growth, metabolism and survival. mTOR exists in two different complexes, mTOR Complex1 and mTOR Complex2.

TGF-β/Smad signaling pathway as a candidate for EMAST phenotype in colorectal cancer patients [PDF]

, 2020
Objective: Elevated microsatellite alteration at selected tetranucleotide repeats (EMAST) is a prognostic biomarker in colorectal cancer (CRC). EMAST phenotype appears to be linked to deficiency in DNA mismatch repair (MMR) proteins including MSH3.

Protein pyrophosphorylation by inositol pyrophosphates — detection, function, and regulation

FEBS Letters, EarlyView.
Protein pyrophosphorylation is an unusual signaling mechanism that was discovered two decades ago. It can be driven by inositol pyrophosphate messengers and influences various cellular processes. Herein, we summarize the research progress and challenges of this field, covering pathways found to be regulated by this posttranslational modification as ...

Adaptor SKAP-55 binds p21ras activating exchange factor RasGRP1 and negatively regulates the p21ras-ERK pathway in T-Cells [PDF]

, 2008
While the adaptor SKAP-55 mediates LFA-1 adhesion on T-cells, it is not known whether the adaptor regulates other aspects of signaling. SKAP-55 could potentially act as a node to coordinate the modulation of adhesion with downstream signaling.

Whole-genome resequencing with multidimensional annotation revealed pathogenic networks in sirenomelia

Italian Journal of Pediatrics
Background Sirenomelia is a rare and lethal congenital malformation representing the most severe form of caudal dysgenesis, with a stillbirth rate of up to 53%. The genetic basis of sirenomelia remains poorly understood.

Calpain small subunit homodimerization is robust and calcium‐independent

FEBS Letters, EarlyView.
Calpains dimerize via penta‐EF‐hand (PEF) domains. Using single‐molecule force spectroscopy, we measured the strength and kinetics of PEF–PEF homodimer binding. The interaction is robust, shows a transient conformational step before dissociation, and remains largely insensitive to Ca2+.

Gut microbiome and aging—A dynamic interplay of microbes, metabolites, and the immune system

FEBS Letters, EarlyView.
Age‐dependent shifts in microbial communities engender shifts in microbial metabolite profiles. These in turn drive shifts in barrier surface permeability of the gut and brain and induce immune activation. When paired with preexisting age‐related chronic inflammation this increases the risk of neuroinflammation and neurodegenerative diseases.
