The determination of cell membrane permeability and of the absorption and clearance rates is an important step in the pharmacokinetic profiling of a new drug candidate. In a similar way, research in cell biology relies on the development of cell penetratin ...
The use of micropatterns has transformed investigations of dynamic biological processes by enabling the reproducible analysis of live cells using time-lapse fluorescence microscopy. With micropatterns, thousands of individual cells can be efficiently image ...
Persistent cells, representing a small fraction of a bacterial population, are refractory to antibiotic therapy. It is a phenotypic transient state. The underlying mechanisms of persistence remain largely unknown, but even divergent hypotheses agree on a f ...
Sphingomyelin (SM) biosynthesis represents a complex, finely regulated process, mostly occurring in vertebrates. It is intimately linked to lipid transport and it is ultimately carried out by two enzymes, SM synthase 1 and 2, selectively localized in the G ...
Although cyclin-dependent kinase 2 (Cdk2) controls the G1/S transition and promotes DNA replication, it is dispensable for cell cycle progression due to redundancy with Cdk1. Yet Cdk2 also has non-redundant functions that can be revealed in certain genetic ...
Active segregation of bacterial chromosomes usually involves the action of ParB proteins, which bind in proximity of chromosomal origin (oriC) regions forming nucleoprotein complexes - segrosomes. Newly duplicated segrosomes are moved either uni- or bidire ...
Numerous diseases affecting living beings have as a cause a modification of gene expression resulting in anomalous expression of proteins in up- or down-regulated fashion, with altered functions or expression of proteins that are not present in the cell in ...
Mycobacteria possess a multi-layered cell wall that requires extensive remodelling during cell division. We investigated the role of an amidase_3 domain-containing N-acetylmuramyl-L-alanine amidase, a peptidoglycan remodelling enzyme implicated in cell div ...
Protein synthesis is an energy-demanding cellular process. Consequently, a well-timed, fine-tuned and plastic regulation of translation is needed to adjust and maintain cell states under dynamically changing environments. Genome-wide monitoring of translat ...
The roles of CDK4 in the cell cycle have been extensively studied, but less is known about the mechanisms underlying the metabolic regulation by CDK4. Here, we report that CDK4 promotes anaerobic glycolysis and represses fatty acid oxidation in mouse embry ...
