(the preferential inactivation of one of the two X chromosomes) may play a role in lupus. Another perspective considers XIST RNA and its protein interactors as potential targets for autoimmune responses, providing insight into the increased SLE propensity in individuals with extra XIST molecules, ...
Mechanical stimuli can also be replicated using PDMS chips, due to their relative flexibility, making it a good candidate for use in kidney-on-a-chip models (Leung et al. 2022). However, one of the main limitations of PDMS chips is their permeability to small hydrophobic molecules (Grant ...
