In many biological systems mechanical forces regulate gene expression: in bacteria changes in turgor pressure cause a deformation of the membrane and induce the expression of osmoregulatory genes; in plants gravity regulates cell growth ('geotropism'); in mammals stretching a muscle induces hypertrophy which is accompanied by qualitative changes in protein synthesis. Consequently, the term 'mechanogenetic control' seems to be a suitable common name for all these processes. The mechanism by which mechanical factors modulate transcriptional activity is still unknown. The purpose of this review is to bring together data from different fields in order to obtain a better understanding of the mechanogenetic control of cell growth.

Background: Recent studies show that hyperactivation of mTOR (mammalian target of rapamycin) signaling plays a causal role in the development of thoracic aortic aneurysm and dissection. Modulation of PP2A (protein phosphatase 2A) activity has been shown to be of significant therapeutic value. In light of the effects that PP2A can exert on the mTOR pathway, we hypothesized that PP2A activation by small-molecule activators of PP2A could mitigate AA progression in Marfan syndrome (MFS).

Flotillin 1 and 2 are highly conserved and homologous members of the stomatin, prohibitin, flotillin, HflK/C (SPFH) family. These ubiquitous proteins assemble into hetero-oligomers at the cytoplasmic membrane in sphingolipid-enriched domains. Flotillins play crucial roles in various cellular processes, likely by concentrating sphingosine.

Single-atom catalysts (SACs) dispersed on support materials exhibit exceptional catalytic properties that can be fine-tuned through interactions between the single atoms and the support. However, selectively controlling the spatial location of single metal atoms while simultaneously harmonizing their coordination environment remains a significant challenge. Here, we present a phenolic-mediated interfacial anchoring (PIA) strategy to prepare SACs with Fe single atoms anchored on the surface of heteroatom-doped carbon nanospheres.
