Crosstalk between tissue mechanics and BMP4 signaling regulates symmetry breaking in human gastrula models
Crosstalk between tissue mechanics and BMP4 signaling regulates symmetry breaking in human gastrula models
Brivanlou and colleagues used optogenetics to spatially control BMP4 expression in human stem cell models across different mechanical regimes. By combining these experiments with mathematical modeling, they dissected how biochemical signals and mechanical forces integrate to initiate symmetry breaking at the onset of gastrulation.

The goal of a PhD is not to learn some facts or read a few papers or learn a bunch of techniques. The goal of a PhD is to learn independence, problem solving, how to finish things you start, resilience, & gain the ability to adapt & think creatively. Learning these things is hard.

A redox switch in p21-CDK feedback during G2 phase controls the proliferation-cell cycle exit decision
A redox switch in p21-CDK feedback during G2 phase controls the proliferation-cell cycle exit decision
ROS oxidize cell cycle proteins and regulate cell proliferation. Vorhauser et al. show that oxidation of the cyclin-dependent kinase (CDK) inhibitor p21 at cysteine 41 (C41) during the G2 phase controls its stability. Loss of C41 oxidation increases p21 stability, impairs proliferation, and promotes senescence after irradiation.
